How many questions are on the ANCC FNP exam and how long is it?

The ANCC FNP-BC exam has 175 questions and a 3.5-hour time limit. Of those, 150 are scored and 25 are unscored pretest items used to evaluate questions for future exams. Most items are multiple choice, with some alternate formats such as drag-and-drop and hotspot questions.

What score do I need to pass the FNP-BC exam?

You need a scaled score of 350 out of 500. Raw scores from the 150 scored questions are converted to a scaled score so candidates taking different exam forms are evaluated fairly. A preliminary pass/fail result appears on screen at the test center immediately after you finish.

What are the five ANCC FNP exam domains and their weights?

The blueprint follows the nursing process: Implementation (29%), Assessment (19%), Planning (19%), Diagnosis (17%), and Evaluation (15%). Implementation is the most heavily weighted domain because ANCC integrates clinical care with professional role, ethics, legal/regulatory issues, and healthcare systems.

How is the ANCC FNP exam different from the AANP FNP exam?

Both certify family nurse practitioners, but ANCC's FNP-BC has five domains and includes professional-role, ethics, legal/regulatory, and healthcare-systems content, while the AANP FNP exam has four domains (Assessment, Diagnosis, Planning, Evaluation) and focuses purely on clinical knowledge. ANCC has 175 questions (150 scored) in 3.5 hours; AANP has 150 questions (135 scored) in 3 hours.

Can I retake the FNP-BC exam if I fail, and is there a waiting period?

Yes. ANCC lets you retest, but you must wait at least 60 days between attempts and you may take the same exam no more than three times in any 12-month period. You submit a new application and pay the exam fee again for each retake. Use the score report from your failed attempt to target the domains where you fell short before testing again.

What is the best way to study for the ANCC FNP-BC exam?

Map your study to the five-domain blueprint and put the most time into Implementation, the largest section, along with the professional-role, ethics, legal/regulatory, and healthcare-systems content that distinguishes ANCC from AANP. Take full-length, domain-weighted practice tests to surface weak areas, then drill them and read every rationale to build clinical judgment rather than rote recall. Most candidates prepare over several focused weeks until they consistently score above the passing threshold on practice exams.

What is the most appropriate initial test to evaluate a patient for possible acute myocardial infarction (AMI)?
- Electrocardiogram (ECG)
- Chest X-ray
- Complete metabolic panel
- Troponin I levels
Correct answer: Electrocardiogram (ECG)
Correct answer: Electrocardiogram (ECG). Explanation: An ECG is the most appropriate initial test for evaluating a patient with suspected AMI because it can quickly identify ischemic changes or infarct that indicate coronary artery blockages.
When assessing a patient with suspected pelvic inflammatory disease, which diagnostic procedure is considered the most definitive?
- Transvaginal ultrasound
- Endometrial biopsy
- Pelvic examination
- Laparoscopy
Correct answer: Laparoscopy
Correct answer: Laparoscopy. Explanation: Laparoscopy is considered the most definitive procedure for diagnosing pelvic inflammatory disease as it allows direct visualization of the pelvic organs.
In evaluating a patient with suspected celiac disease, which of the following tests is considered most specific for diagnosing this condition?
- Total IgA
- Tissue Transglutaminase IgA
- Complete blood count
- Stool fat content
Correct answer: Tissue Transglutaminase IgA
Correct answer: Tissue Transglutaminase IgA. Explanation: Tissue Transglutaminase IgA is highly specific for celiac disease and is used primarily in its diagnosis, making it an essential test for patients presenting with symptoms suggestive of this condition.
For a patient experiencing symptoms of a urinary tract infection, which of the following is the most appropriate initial diagnostic test?
- Urine culture
- Urinalysis
- Cystoscopy
- Blood urea nitrogen (BUN)
Correct answer: Urinalysis
Correct answer: Urinalysis. Explanation: Urinalysis is the most appropriate initial diagnostic test for a suspected urinary tract infection as it can quickly identify the presence of leukocytes, nitrites, and bacteria.
Which diagnostic test is most useful for initially evaluating a patient with suspected congestive heart failure?
- Echocardiogram
- Electrocardiogram (ECG)
- Chest X-ray
- Serum electrolytes
Correct answer: Echocardiogram
Correct answer: Echocardiogram. Explanation: An echocardiogram is the most useful initial test for evaluating a patient with suspected congestive heart failure because it provides detailed images of the heart's structure and function, helping to assess ventricular performance and fluid status.
In the evaluation of a patient with severe abdominal pain, which diagnostic test is essential to differentiate between acute pancreatitis and other causes of abdominal pain?
- Abdominal ultrasound
- Lipase level
- Lactate dehydrogenase (LDH)
- Serum amylase
Correct answer: Lipase level
Correct answer: Lipase level. Explanation: Lipase levels are more specific than amylase for acute pancreatitis and remain elevated longer during the course of the disease, making it an essential test for differentiating this condition from other causes of abdominal pain.
For a patient presenting with new neurological symptoms, which imaging study is most appropriate to evaluate for potential multiple sclerosis?
- CT Scan of the head
- MRI of the brain and spinal cord
- X-ray of the spine
- PET scan
Correct answer: MRI of the brain and spinal cord
Correct answer: MRI of the brain and spinal cord. Explanation: MRI of the brain and spinal cord is the most appropriate and sensitive imaging study for detecting the characteristic lesions of multiple sclerosis and assessing the extent of neurological involvement.
In evaluating a patient with chronic cough and weight loss, which test is critical for diagnosing tuberculosis?
- Chest X-ray
- Sputum culture for Mycobacterium tuberculosis
- Pulmonary function test
- CT scan of the chest
Correct answer: Sputum culture for Mycobacterium tuberculosis
Correct answer: Sputum culture for Mycobacterium tuberculosis. Explanation: Sputum culture for Mycobacterium tuberculosis is critical for confirming the diagnosis of tuberculosis, as it provides a definitive identification of the presence of the TB bacteria.
A patient with suspected peripheral arterial disease 'PAD' has intermittent claudication. Which test is most appropriate to confirm the diagnosis?
- Ankle-brachial index (ABI)
- Doppler ultrasound of the lower extremities
- Arteriography
- Treadmill exercise test
Correct answer: Ankle-brachial index (ABI)
Correct answer: Ankle-brachial index (ABI). Explanation: The ankle-brachial index (ABI) is a simple, non-invasive test that measures the ratio of the blood pressure in the lower legs to the blood pressure in the arms, which is most indicative of PAD.
What is the most appropriate test to evaluate a patient with suspected acute glomerulonephritis?
- Renal biopsy
- Urine protein
- Serum creatinine
- 24-hour urine collection for protein
Correct answer: Renal biopsy
Correct answer: Renal biopsy. Explanation: Renal biopsy is the most definitive test for diagnosing glomerulonephritis, allowing direct visualization and assessment of glomerular damage.
For evaluating a child with suspected growth hormone deficiency, which test provides the most definitive information?
- Serum growth hormone level
- Bone age X-ray
- Growth hormone stimulation test
- Insulin-like growth factor 1 (IGF-1) level
Correct answer: Growth hormone stimulation test
Correct answer: Growth hormone stimulation test. Explanation: The growth hormone stimulation test, which measures the response of the pituitary gland to provocation, provides the most definitive information on growth hormone production status.
When assessing a patient with suspected preeclampsia, which diagnostic measure is most critical?
- Blood pressure measurement
- Urine protein quantification
- Liver function tests
- Complete blood count (CBC)
Correct answer: Urine protein quantification
Correct answer: Urine protein quantification. Explanation: Urine protein quantification is critical for the diagnosis of preeclampsia, as significant proteinuria is a hallmark feature of this condition, alongside high blood pressure.
In the evaluation of a patient with new-onset ascites, which diagnostic test is essential to determine the cause?
- Liver function tests
- Abdominal ultrasound
- Paracentesis
- Serum-ascites albumin gradient (SAAG)
Correct answer: Paracentesis
Correct answer: Paracentesis. Explanation: Paracentesis, the extraction of fluid from the abdomen, is essential for analyzing ascitic fluid to determine the cause of ascites, whether due to liver disease, infection, or malignancy.
A nurse is caring for a patient undergoing treatment for tuberculosis. What is the most important instruction to give to ensure effective treatment?
- Complete the full course of antibiotics, even if symptoms improve
- Take antibiotics only when experiencing coughing fits
- Discontinue medication as soon as the test results are negative
- Use antibiotics intermittently to prevent resistance
Correct answer: Complete the full course of antibiotics, even if symptoms improve
Correct answer: Complete the full course of antibiotics, even if symptoms improve. Explanation: Completing the full course of prescribed antibiotics is critical to prevent the development of drug-resistant tuberculosis and ensure the infection is fully eradicated.
When planning care for a patient with acute pancreatitis, what nursing intervention is essential to manage pain and prevent complications?
- Encourage frequent, heavy meals to assess digestive function
- Administer analgesics and maintain NPO status as prescribed
- Recommend alcohol consumption to stimulate pancreatic activity
- Increase activity level to enhance metabolic rate
Correct answer: Administer analgesics and maintain NPO status as prescribed
Correct answer: Administer analgesics and maintain NPO status as prescribed. Explanation: Managing pain with analgesics and minimizing pancreatic stimulation through NPO (nothing by mouth) status are key to managing acute pancreatitis and preventing further complications.
For a patient with severe allergic rhinitis, what is the best nursing practice to reduce symptom severity during peak allergy season?
- Recommend keeping windows open to ensure fresh air circulation
- Advise the patient to avoid known allergens and use air purifiers
- Encourage outdoor exercise to boost immune response
- Suggest discontinuing any use of antihistamines to prevent dependency
Correct answer: Advise the patient to avoid known allergens and use air purifiers
Correct answer: Advise the patient to avoid known allergens and use air purifiers. Explanation: Avoiding exposure to allergens and using air purifiers can significantly reduce the severity of symptoms in patients with severe allergic rhinitis.
A 46-year-old man with no personal or family history of colorectal disease presents to establish primary care. He has never been screened for colorectal cancer. According to the current USPSTF recommendation, which action is most appropriate?
- Defer screening until age 50, then offer colonoscopy
- Begin colorectal cancer screening now, because routine screening is recommended for average-risk adults starting at age 45
- Screen only if he develops rectal bleeding or a change in bowel habits
- Order a single carcinoembryonic antigen (CEA) level as a screening test
Correct answer: Begin colorectal cancer screening now, because routine screening is recommended for average-risk adults starting at age 45
Beginning colorectal cancer screening now is correct because the USPSTF recommends routine screening for average-risk adults beginning at age 45 and continuing through age 75 (the starting age was lowered from 50 to 45 in 2021 due to rising incidence in younger adults). Waiting until 50 reflects the outdated threshold. Screening is a preventive measure for asymptomatic patients, so it should not be delayed until symptoms appear, and CEA is a tumor marker for monitoring, not a screening test.
When counseling an average-risk 45-year-old about colorectal cancer screening options, the patient prefers a noninvasive stool-based test done at home. Which option best fits this request while remaining an acceptable screening modality?
- Flexible sigmoidoscopy performed in the office today
- Abdominal CT scan without contrast
- Fecal immunochemical test (FIT) performed annually
- Serum carcinoembryonic antigen drawn at the next visit
Correct answer: Fecal immunochemical test (FIT) performed annually
An annual fecal immunochemical test (FIT) is correct because it is a USPSTF-endorsed noninvasive, home-collected stool test that detects human hemoglobin and is recommended yearly for average-risk screening. The FIT does not require bowel prep or dietary restriction. Flexible sigmoidoscopy is invasive and office-based, abdominal CT without contrast is not a colorectal screening test, and CEA is a monitoring marker rather than a screening tool.
A 50-year-old asks the nurse practitioner when a colonoscopy is the appropriate screening interval for someone at average risk with a normal prior exam. Which interval is correct?
- Every 10 years
- Every 3 years
- Every 20 years
- Every year
Correct answer: Every 10 years
Every 10 years is correct because for average-risk adults a normal screening colonoscopy is repeated at 10-year intervals, the longest interval among the recommended modalities because of its high sensitivity and ability to remove polyps. Stool-based FIT is annual and stool DNA testing is every 1 to 3 years, but those shorter intervals apply to those tests, not to a normal colonoscopy.
A healthy 24-year-old woman who is sexually active with a new partner presents for an annual visit. She has no symptoms. According to CDC and USPSTF guidance, which screening should the nurse practitioner recommend?
- Annual screening for chlamydia and gonorrhea using a nucleic acid amplification test
- No STI screening because she is asymptomatic
- Herpes simplex virus serology as routine screening
- Screening only if she requests it after symptoms develop
Correct answer: Annual screening for chlamydia and gonorrhea using a nucleic acid amplification test
Annual chlamydia and gonorrhea screening with a nucleic acid amplification test (NAAT) is correct because the CDC and USPSTF recommend yearly screening for all sexually active women younger than 25, and for those 25 and older with risk factors such as a new partner. A vaginal swab or first-catch urine NAAT is the preferred method. Screening is recommended precisely because most infections are asymptomatic, so waiting for symptoms misses cases, and routine HSV serology is not recommended in asymptomatic people.
Which patient population does the CDC identify for routine annual screening for both chlamydia and gonorrhea regardless of symptoms?
- Only men who report dysuria
- All sexually active women younger than 25 years
- Only women older than 40 years
- Only pregnant women in the third trimester
Correct answer: All sexually active women younger than 25 years
All sexually active women younger than 25 years is correct because CDC STI screening recommendations call for annual NAAT screening for chlamydia and gonorrhea in this group, who carry the highest infection burden. Women 25 and older are screened when at increased risk. Routine annual screening is not limited to women over 40 or to symptomatic men, and pregnant women are screened at the first prenatal visit rather than only in the third trimester.
An average-risk 22-year-old woman has never had a Pap test. She asks when cervical cancer screening should begin. Which response reflects current guidance?
- Screening should have started at first intercourse regardless of age
- Screening begins at age 18 with annual Pap tests
- Screening begins at age 21, with cytology (Pap test) every 3 years for ages 21 to 29
- Screening is not needed until age 30 if she feels well
Correct answer: Screening begins at age 21, with cytology (Pap test) every 3 years for ages 21 to 29
Beginning screening at age 21 with cytology every 3 years for ages 21 to 29 is correct because guidelines recommend against screening anyone younger than 21 and call for Pap-only testing every 3 years in the 21-to-29 group. Screening is not initiated at sexual debut or at age 18 because cervical cancer is rare before 21 and earlier screening leads to unnecessary procedures. Waiting until 30 would leave women 21 to 29 unscreened.
A 40-year-old woman at average risk for breast cancer asks the nurse practitioner when she should begin mammography. Based on the current USPSTF recommendation, which answer is correct?
- Mammography is recommended only after a breast lump is found
- Wait until age 50 to start screening
- Begin biennial screening mammography at age 40 and continue every 2 years through age 74
- Begin annual mammography at age 30
Correct answer: Begin biennial screening mammography at age 40 and continue every 2 years through age 74
Beginning biennial screening mammography at age 40 through age 74 is correct because the USPSTF updated its recommendation in 2024 to start screening at 40 (lowered from 50) every other year for average-risk women. Starting at 30 is too early for average risk, deferring to 50 reflects the prior guidance, and mammography is a screening test for asymptomatic women rather than a test reserved for after a palpable lump.
A 38-year-old woman reports several weeks of fatigue, cold intolerance, and constipation. The nurse practitioner orders thyroid studies and finds an elevated TSH with a low free T4. How should these results be interpreted?
- Secondary (central) hypothyroidism
- Hyperthyroidism (thyrotoxicosis)
- Primary hypothyroidism
- Euthyroid sick syndrome with normal thyroid function
Correct answer: Primary hypothyroidism
Primary hypothyroidism is correct because a high TSH with a low free T4 indicates the thyroid gland is failing to produce adequate hormone while the pituitary appropriately raises TSH in compensation. In hyperthyroidism the TSH is suppressed and free T4 is high. Secondary (central) hypothyroidism shows a low or inappropriately normal TSH with a low free T4 because the pituitary is the problem, which is the opposite TSH pattern.
A nurse practitioner reviews a complete blood count showing a hemoglobin of 9.8 g/dL with a mean corpuscular volume (MCV) of 72 fL. Which classification best describes this anemia and what is the most likely cause?
- Hemolytic anemia from G6PD deficiency
- Macrocytic anemia, most commonly from B12 deficiency
- Normocytic anemia of acute blood loss
- Microcytic anemia, most commonly from iron deficiency
Correct answer: Microcytic anemia, most commonly from iron deficiency
Microcytic anemia most commonly from iron deficiency is correct because an MCV below about 80 fL defines microcytosis, and iron deficiency is the most common cause in primary care. Macrocytic anemia (B12 or folate deficiency) shows an MCV above roughly 100 fL, and normocytic anemia has an MCV in the normal range, so neither fits an MCV of 72. Interpreting the CBC starts with the hemoglobin to confirm anemia, then the MCV to size the red cells.
A 30-year-old presents with fatigue and is found to be anemic with a low MCV. To complete the anemia workup and confirm iron deficiency, which laboratory finding pattern would be expected?
- Normal ferritin with elevated B12
- Low ferritin with elevated total iron-binding capacity (TIBC)
- Elevated MCV with low reticulocyte count
- High ferritin with low TIBC
Correct answer: Low ferritin with elevated total iron-binding capacity (TIBC)
Low ferritin with an elevated total iron-binding capacity is correct because depleted iron stores lower ferritin while the body upregulates transferrin, raising TIBC, the classic iron-deficiency pattern. Ferritin is the single most useful test for confirming iron deficiency. A high ferritin with low TIBC suggests anemia of chronic disease, and an elevated MCV points to a macrocytic process rather than iron deficiency.
A 28-year-old reports three months of persistent fatigue without an obvious cause on history. Which initial laboratory panel is the most appropriate evidence-based starting point?
- Brain MRI and lumbar puncture
- Serum heavy-metal screen and Lyme Western blot as first-line tests
- Antinuclear antibody and rheumatoid factor only
- Complete blood count, thyroid-stimulating hormone, and a basic metabolic panel
Correct answer: Complete blood count, thyroid-stimulating hormone, and a basic metabolic panel
Ordering a CBC, TSH, and basic metabolic panel is correct because the most common reversible causes of unexplained fatigue (anemia, thyroid dysfunction, and electrolyte or glucose abnormalities) are captured by these inexpensive first-line tests. Advanced imaging, autoimmune serologies, and specialized exposure panels are not indicated initially without specific clinical findings to direct them and would represent low-value testing.
A 55-year-old man with diabetes and a 30-pack-year smoking history reports calf pain with walking that resolves with rest. The nurse practitioner performs an ankle-brachial index (ABI) and obtains a value of 0.78. How should this result be interpreted?
- Normal arterial flow requiring no further action
- Peripheral artery disease (an ABI below 0.90 is abnormal)
- Noncompressible, calcified vessels
- Borderline result that is within the normal range
Correct answer: Peripheral artery disease (an ABI below 0.90 is abnormal)
Peripheral artery disease is correct because an ABI of 0.90 or less is diagnostic of PAD, and a value of 0.78 fits mild-to-moderate disease in a patient whose claudication and risk factors already raise suspicion. A normal ABI is roughly 1.00 to 1.40, a borderline result is 0.91 to 0.99, and values above 1.40 suggest noncompressible calcified vessels seen in diabetes, none of which apply to 0.78.
A 19-year-old presents with a sore throat. The nurse practitioner applies the modified Centor (McIsaac) score to estimate the likelihood of group A streptococcal pharyngitis. Which set of findings is part of that scoring tool?
- Blood pressure, heart rate, respiratory rate, and oxygen saturation
- Presence of cough, rhinorrhea, conjunctivitis, and hoarseness
- White blood cell count, C-reactive protein, and procalcitonin level
- Fever over 38 C, tonsillar exudate, tender anterior cervical nodes, absence of cough, and age
Correct answer: Fever over 38 C, tonsillar exudate, tender anterior cervical nodes, absence of cough, and age
Fever over 38 C, tonsillar exudate, tender anterior cervical lymphadenopathy, absence of cough, and age adjustment is correct because these are the components of the modified Centor (McIsaac) score, which estimates the probability of group A strep and guides testing decisions. Cough, rhinorrhea, and conjunctivitis suggest a viral cause and the absence of cough actually adds a point. Inflammatory labs and vital-sign panels are not part of the Centor criteria.
During a wellness visit, a 45-year-old screens positive on a PHQ-2. The nurse practitioner administers the full PHQ-9, and the patient scores 16. How should this score be interpreted?
- A normal result that rules out depression
- Minimal symptoms requiring no follow-up
- Severe anxiety requiring benzodiazepine therapy
- Moderately severe depressive symptoms warranting further evaluation and treatment discussion
Correct answer: Moderately severe depressive symptoms warranting further evaluation and treatment discussion
Moderately severe depressive symptoms is correct because PHQ-9 scores of 15 to 19 fall in the moderately severe range, and a score of 16 should prompt evaluation for major depression and a discussion of treatment. The cutoffs are 5 to 9 mild, 10 to 14 moderate, 15 to 19 moderately severe, and 20 or higher severe, so 16 is neither minimal nor normal. The PHQ-9 measures depression, not anxiety.
A 33-year-old reports several weeks of excessive worry, restlessness, and difficulty relaxing. The nurse practitioner chooses a validated brief instrument to screen for generalized anxiety disorder. Which tool is most appropriate?
- GAD-7
- Morse Fall Scale
- CAGE questionnaire
- Mini-Mental State Examination
Correct answer: GAD-7
The GAD-7 is correct because it is a validated 7-item screening instrument for generalized anxiety disorder, with scores of 5, 10, and 15 marking mild, moderate, and severe anxiety. The Mini-Mental State Examination assesses cognition, the CAGE questionnaire screens for alcohol use disorder, and the Morse Fall Scale predicts fall risk, so none of those address anxiety symptoms.
A parent brings a 9-month-old for a well-child visit. The nurse practitioner wants to use a standardized tool to evaluate whether the infant is meeting developmental milestones across multiple domains. Which instrument is designed for this purpose?
- Braden Scale
- Wong-Baker FACES pain rating scale
- Denver Developmental Screening Test (Denver II)
- Glasgow Coma Scale
Correct answer: Denver Developmental Screening Test (Denver II)
The Denver Developmental Screening Test (Denver II) is correct because it is a standardized screening tool that assesses gross motor, fine motor, language, and personal-social development in children from birth to about 6 years. The Glasgow Coma Scale measures level of consciousness, the Braden Scale predicts pressure-injury risk, and the Wong-Baker FACES scale rates pain, so none assess developmental milestones.
At a well-child visit, a healthy 12-month-old is being assessed. Which finding represents an expected developmental milestone for this age?
- Riding a tricycle and copying a circle
- Walking up stairs independently and speaking in three-word sentences
- Rolling over for the first time and tracking to midline only
- Pulling to stand, saying one or two words, and using a pincer grasp
Correct answer: Pulling to stand, saying one or two words, and using a pincer grasp
Pulling to stand, saying one or two words, and using a pincer grasp is correct because these are typical 12-month milestones spanning gross motor, language, and fine motor domains. Walking up stairs and three-word sentences are closer to 2 to 3 years, rolling over and tracking to midline are early-infant skills around 4 months, and riding a tricycle and copying a circle are roughly 3-year skills. Assessing milestones means matching observed skills to age-expected norms across each developmental domain.
A 4-year-old has a soft, grade II systolic murmur heard best at the left lower sternal border. The child is asymptomatic, growing normally, and the murmur softens when she stands. Which feature most supports classifying this as an innocent (functional) murmur?
- A harsh holosystolic murmur radiating to the axilla
- A soft, grade I to II systolic murmur in an asymptomatic child that changes with position
- A continuous murmur with an associated thrill
- A diastolic murmur heard at the apex
Correct answer: A soft, grade I to II systolic murmur in an asymptomatic child that changes with position
A soft, grade I to II systolic murmur that changes with position in an asymptomatic, normally growing child is correct because innocent murmurs are low-grade, systolic, vary with positioning or activity, and occur without symptoms or other cardiac findings. Diastolic murmurs, continuous murmurs, harsh holosystolic murmurs, and any murmur with a palpable thrill (grade IV or higher) are pathologic features that require cardiology evaluation rather than reassurance.
During a skin examination, a nurse practitioner evaluates a pigmented lesion on a patient's back using the ABCDE rule. Which set of features best reflects what this rule prompts the clinician to assess for possible melanoma?
- Asymmetry, border irregularity, color variation, diameter over 6 mm, and evolution over time
- Annular shape, blistering, central clearing, dryness, and erythema
- Age, body mass index, cholesterol, diabetes, and exercise habits
- Atrophy, bruising, crusting, dimpling, and edema
Correct answer: Asymmetry, border irregularity, color variation, diameter over 6 mm, and evolution over time
Asymmetry, border irregularity, color variation, diameter greater than 6 mm, and evolution is correct because the ABCDE rule is the standard mnemonic for identifying melanoma warning signs during a skin assessment, with the E (evolving lesion) being a particularly important red flag. The other groupings describe unrelated dermatologic or general-health features and do not correspond to the melanoma screening mnemonic, which is meant to flag suspicious lesions for biopsy or referral.
While palpating the right upper quadrant of a patient with suspected acute cholecystitis, the nurse practitioner asks the patient to take a deep breath. The patient abruptly stops inspiration because of pain as the inflamed gallbladder descends against the examining fingers. What is this elicited finding called?
- Rovsing's sign
- Murphy's sign
- McBurney's point tenderness
- Cullen's sign
Correct answer: Murphy's sign
Murphy's sign is the correct finding. It is elicited by palpating beneath the right costal margin while the patient inhales; an inspiratory arrest from pain as the inflamed gallbladder meets the fingers indicates the sign is positive and supports gallbladder inflammation. McBurney's point tenderness localizes to the right lower quadrant and points toward appendiceal inflammation, not the gallbladder. Rovsing's sign refers to right lower quadrant pain provoked by palpating the left lower quadrant, again an appendicitis maneuver. Cullen's sign is periumbilical bruising associated with intraperitoneal or retroperitoneal hemorrhage, such as in hemorrhagic pancreatitis, and is unrelated to this respiratory-arrest maneuver.
A patient reports decreased hearing in the left ear. The nurse practitioner places a vibrating 512 Hz tuning fork on the midline of the forehead, and the patient reports the sound is louder in the left (affected) ear. How should this Weber test result be interpreted?
- Sensorineural hearing loss in the left ear
- Sensorineural hearing loss in the right ear
- Conductive hearing loss in the left ear
- Normal hearing bilaterally
Conductive hearing loss in the left ear is the correct interpretation. In the Weber test, sound lateralizes toward the ear with a conductive deficit because that ear is shielded from competing ambient noise and transmits bone-conducted sound more efficiently, so louder perception in the affected ear indicates conduction loss on that side. Sensorineural loss in the left ear would cause the sound to lateralize away from the affected side, toward the right. Normal hearing produces a midline sound heard equally in both ears, not lateralization. Sensorineural loss in the right ear would also lateralize the tone to the left, but it would be paired with a Rinne test showing air conduction greater than bone conduction in the better-hearing pattern, which does not fit a left-sided complaint with left lateralization.
A patient presents with abdominal pain. To structure a thorough symptom history, the nurse practitioner uses the OLDCARTS mnemonic. Which element of this mnemonic specifically captures what makes the pain better or worse?
- Aggravating and alleviating factors
- Timing
- Onset
- Radiation
Aggravating and alleviating factors is correct. Within OLDCARTS the 'A' captures what worsens or relieves the symptom, such as eating, movement, or position, which helps differentiate causes of abdominal pain. Onset records when the symptom began and how suddenly, not what modifies it. Radiation describes where the pain travels, such as to the back or shoulder, rather than provoking or relieving influences. Timing addresses the pattern and duration over time, including whether it is constant or intermittent, and likewise does not capture aggravating or relieving factors.
A patient with headache, fever, and neck stiffness is being assessed for meningeal irritation. The nurse practitioner passively flexes the patient's neck and observes that this causes involuntary flexion of the patient's hips and knees. Which physical examination sign does this maneuver demonstrate?
- Babinski sign
- Romberg sign
- Kernig sign
- Brudzinski sign
Brudzinski sign is correct. It is positive when passive neck flexion provokes involuntary flexion of the hips and knees, a response to meningeal irritation. Kernig sign is a different meningeal maneuver in which extending the knee while the hip is flexed produces pain and resistance, not reflexive hip and knee flexion from neck movement. Babinski sign is an upper motor neuron finding elicited by stroking the sole, producing dorsiflexion of the great toe, and has nothing to do with neck flexion. Romberg sign assesses proprioception and balance by having the patient stand with eyes closed, unrelated to meningeal testing.
During a dilated fundoscopic examination of a patient with poorly controlled diabetes, the nurse practitioner notes small, fluffy, white-gray patches with indistinct edges on the retina. These represent microinfarcts of the retinal nerve fiber layer. What are these findings called?
- Drusen
- Hard exudates
- Cotton-wool spots
- Roth spots
Cotton-wool spots is correct. They are soft, fluffy, white-gray retinal lesions with blurred margins caused by microinfarction of the nerve fiber layer and are seen in diabetic and hypertensive retinopathy. Drusen are discrete yellow deposits beneath the retina associated with age-related macular degeneration, and they have sharper borders than cotton-wool spots. Hard exudates are well-defined, waxy yellow lipid deposits, distinct from the soft, indistinct appearance described. Roth spots are retinal hemorrhages with pale centers classically linked to infective endocarditis, not the diffuse fluffy microinfarcts characteristic of this patient.
On cardiac auscultation of a 58-year-old with exertional dyspnea, the nurse practitioner hears a low-pitched extra heart sound just after S2, best heard at the apex with the bell while the patient lies in the left lateral decubitus position. In an adult, this sound most likely reflects which underlying problem?
- Stiff, noncompliant ventricle resisting late atrial filling
- Stenosis of the aortic valve restricting outflow
- Pericardial inflammation with a friction component
- Elevated left ventricular filling pressure and volume overload
Elevated left ventricular filling pressure and volume overload is correct. The sound described is an S3 gallop, a low-pitched early-diastolic sound following S2 that in adults signals increased ventricular filling pressures and is associated with systolic heart failure and volume overload. A stiff, noncompliant ventricle resisting late atrial filling produces an S4, which occurs just before S1, not after S2. Aortic valve stenosis produces a systolic ejection murmur rather than a diastolic gallop. Pericardial inflammation produces a scratchy three-component friction rub heard throughout the cardiac cycle, not a discrete low-pitched post-S2 sound.
A patient with a large pericardial effusion is being evaluated for cardiac tamponade. The nurse practitioner uses a blood pressure cuff to measure the difference in systolic pressure between expiration and inspiration. An exaggerated drop in systolic blood pressure greater than 10 mmHg during inspiration is identified. What is this finding called?
- Pulsus paradoxus
- Water-hammer pulse
- Pulsus bisferiens
- Pulsus alternans
Pulsus paradoxus is correct. It is an exaggerated fall in systolic blood pressure of more than 10 mmHg during inspiration, classically measured with a manual cuff and associated with cardiac tamponade, severe asthma, and constrictive physiology. Pulsus alternans is a beat-to-beat alternation in pulse amplitude seen in severe left ventricular dysfunction, not a respiratory-phase pressure drop. A water-hammer (Corrigan) pulse is a bounding, rapidly collapsing pulse typical of aortic regurgitation. Pulsus bisferiens is a double-peaked pulse found in conditions such as hypertrophic obstructive cardiomyopathy or mixed aortic valve disease, distinct from the inspiratory pressure drop described.
During a well-adolescent visit, the nurse practitioner assesses pubertal development in a 13-year-old. Which standardized assessment framework is used to stage the physical progression of secondary sexual characteristics?
- Braden scale
- Apgar scoring
- Glasgow Coma Scale
- Tanner staging (sexual maturity rating)
Tanner staging, also called the sexual maturity rating, is correct. It is the standard framework for classifying the physical progression of secondary sexual characteristics such as breast, genital, and pubic hair development across adolescence. Apgar scoring evaluates newborn status immediately after birth using heart rate, respiration, tone, reflex, and color, not pubertal progression. The Glasgow Coma Scale grades level of consciousness after neurologic injury. The Braden scale predicts pressure injury risk, none of which assess sexual maturity.
A nurse practitioner is assessing peripheral perfusion in a toddler with vomiting and reduced oral intake. After pressing on the child's fingertip until the skin blanches and then releasing, color returns in about 4 seconds. How should this capillary refill finding be interpreted?
- An expected response to a warm ambient environment
- A finding specific to congenital heart disease
- Prolonged capillary refill, suggesting hypovolemia or poor perfusion
- Normal capillary refill for a child
Prolonged capillary refill suggesting hypovolemia or poor perfusion is correct. Normal capillary refill is under 2 seconds, so a return of color taking about 4 seconds is delayed and, in a child with vomiting and decreased intake, points toward dehydration and reduced peripheral perfusion. Calling it normal for a child is incorrect because the expected threshold is less than 2 seconds. The finding is not specific to congenital heart disease; delayed refill reflects perfusion broadly rather than a single cardiac diagnosis. A warm ambient environment tends to speed, not slow, capillary refill, so it does not explain the prolonged time.
An adult patient has no symptoms of hyperglycemia. Which single result, when confirmed by repeat testing on a separate day, establishes a diagnosis of diabetes mellitus per the 2026 ADA Standards of Care?
- 2-hour OGTT plasma glucose of 170 mg/dL
- Random plasma glucose of 160 mg/dL
- Hemoglobin A1c of 6.5 percent or higher
- Fasting plasma glucose of 110 mg/dL
Correct answer: Hemoglobin A1c of 6.5 percent or higher
A hemoglobin A1c of 6.5 percent or higher meets the diagnostic threshold for diabetes. The 2026 ADA criteria define diabetes by any of: A1c 6.5 percent or higher, fasting plasma glucose 126 mg/dL or higher, 2-hour OGTT value 200 mg/dL or higher, or a random glucose 200 mg/dL or higher with classic symptoms. Because this patient has no symptoms, a confirmatory repeat test is required, and the fasting glucose of 110 mg/dL and OGTT of 170 mg/dL fall in the prediabetes/impaired range rather than the diabetes range.
A 52-year-old patient with classic polyuria, polydipsia, and unexplained weight loss has a single random plasma glucose of 268 mg/dL. Which statement about diagnosing type 2 diabetes in this patient is correct?
- An A1c below 6.5 percent would rule out the diagnosis
- The diagnosis can be made now without a repeat test
- An oral glucose tolerance test must be performed first
- A second confirmatory test on another day is required before diagnosis
Correct answer: The diagnosis can be made now without a repeat test
The diagnosis of diabetes can be made now without a repeat test. Per the 2026 ADA criteria, classic hyperglycemic symptoms plus a random plasma glucose of 200 mg/dL or higher is diagnostic on its own, so confirmatory testing is not needed in a symptomatic patient. Repeat or confirmatory testing is reserved for asymptomatic patients diagnosed on the basis of laboratory values alone, and a normal A1c would not override an unequivocally elevated symptomatic glucose.
A 58-year-old asymptomatic patient has an average office blood pressure of 134/82 mm Hg confirmed on two separate visits with proper technique. Using the 2017 ACC/AHA guideline, how is this best classified?
- Stage 2 hypertension
- Elevated blood pressure
- Stage 1 hypertension
- Normal blood pressure
Correct answer: Stage 1 hypertension
This is stage 1 hypertension. The 2017 ACC/AHA thresholds define normal as below 120/80, elevated as 120 to 129 systolic and below 80 diastolic, stage 1 as 130 to 139 systolic or 80 to 89 diastolic, and stage 2 as 140/90 or higher. A reading of 134/82 falls in the stage 1 range, and diagnosis requires an average of at least two readings on at least two occasions.
A 60-year-old smoker reports chronic productive cough and exertional dyspnea. Which spirometry finding is required to confirm a diagnosis of COPD per the GOLD 2026 strategy?
- Pre-bronchodilator FEV1 less than 80 percent predicted
- A 12 percent increase in FEV1 after bronchodilator
- Total lung capacity above 120 percent predicted
- Post-bronchodilator FEV1/FVC ratio less than 0.70
Correct answer: Post-bronchodilator FEV1/FVC ratio less than 0.70
A post-bronchodilator FEV1/FVC ratio less than 0.70 is required to confirm COPD. GOLD 2026 mandates spirometry, and the diagnosis depends on persistent airflow limitation demonstrated by this fixed ratio after a bronchodilator. A significant bronchodilator response suggests an asthmatic component and is not the COPD-defining criterion, and FEV1 percent predicted is used to grade severity once obstruction is confirmed, not to establish the diagnosis.
Under the GOLD framework, after a patient meets the spirometric definition of COPD, the post-bronchodilator FEV1 percent predicted is used primarily to do what?
- Grade the severity of airflow limitation
- Determine the need for spirometry
- Confirm the presence of airflow obstruction
- Rule out asthma as a comorbidity
Correct answer: Grade the severity of airflow limitation
The post-bronchodilator FEV1 percent predicted is used to grade the severity of airflow limitation once COPD is confirmed. GOLD classifies severity as GOLD 1 (mild, FEV1 80 percent or more), GOLD 2 (moderate, 50 to 79 percent), GOLD 3 (severe, 30 to 49 percent), and GOLD 4 (very severe, below 30 percent). The FEV1/FVC ratio below 0.70, not the FEV1 percentage, is what confirms the obstruction.
A 26-year-old has recurrent episodic wheezing, chest tightness, and cough worse at night and with exercise. Which objective test best confirms a diagnosis of asthma?
- Chest radiograph showing hyperinflation
- Elevated serum total IgE level
- Single peak flow reading below predicted
- Spirometry showing reversible airflow obstruction after a bronchodilator
Correct answer: Spirometry showing reversible airflow obstruction after a bronchodilator
Spirometry showing reversible airflow obstruction confirms asthma, classically a 12 percent or greater and 200 mL increase in FEV1 after a bronchodilator. Variable expiratory airflow limitation that is reversible distinguishes asthma from fixed obstruction. A chest film and IgE level are nonspecific, and a single low peak flow value lacks the demonstration of variability or reversibility needed for diagnosis.
A 30-year-old woman reports dysuria, urinary frequency, and urgency without fever, flank pain, or vaginal discharge. Which finding best supports a diagnosis of acute uncomplicated cystitis?
- Positive leukocyte esterase and nitrites on urinalysis
- Costovertebral angle tenderness
- Hematuria with proteinuria on dipstick
- White blood cell casts in the urine sediment
Correct answer: Positive leukocyte esterase and nitrites on urinalysis
Positive leukocyte esterase and nitrites best support acute uncomplicated cystitis. In a woman with classic dysuria, frequency, and urgency and no upper-tract or systemic features, these dipstick markers of pyuria and Enterobacteriaceae make a urinary tract infection likely enough to treat empirically. Costovertebral angle tenderness and white blood cell casts point to pyelonephritis rather than simple cystitis.
A nurse practitioner reviews an asymptomatic woman's screening urine culture growing 100,000 colony-forming units per mL with pyuria; the patient denies dysuria, frequency, urgency, or suprapubic discomfort. What is the most accurate diagnostic interpretation?
- Interstitial cystitis
- Acute cystitis requiring antibiotics
- Asymptomatic bacteriuria
- Pyelonephritis
Correct answer: Asymptomatic bacteriuria
This is asymptomatic bacteriuria, defined by significant bacteriuria (at least 100,000 colony-forming units per mL) without urinary symptoms. A urinary tract infection requires both significant bacteriuria and compatible symptoms such as dysuria, frequency, urgency, or suprapubic pain. Diagnosing cystitis or pyelonephritis here would mislabel a finding that, outside pregnancy and certain procedures, does not warrant antibiotics.
A 45-year-old woman has fatigue, cold intolerance, constipation, and weight gain. Which laboratory pattern confirms primary hypothyroidism?
- Normal TSH with low free T4
- Elevated TSH with low free T4
- Low TSH with low free T4
- Low TSH with high free T4
Correct answer: Elevated TSH with low free T4
Elevated TSH with low free T4 confirms primary hypothyroidism. When the thyroid gland fails, the pituitary increases TSH output while circulating free T4 falls. Low TSH with high free T4 indicates hyperthyroidism, and a low TSH with low free T4 suggests central (pituitary or hypothalamic) hypothyroidism rather than a primary gland problem.
A 50-year-old has minimal symptoms; labs show a TSH of 7.8 mIU/L with a normal free T4. Antithyroid antibodies are pending. What is the most accurate diagnosis?
- Overt primary hypothyroidism
- Subclinical hypothyroidism
- Central hypothyroidism
- Euthyroid sick syndrome
Correct answer: Subclinical hypothyroidism
A mildly elevated TSH (commonly 4.5 to 10 mIU/L) with a normal free T4 and few or no symptoms defines subclinical hypothyroidism. Overt hypothyroidism requires a low free T4, and central hypothyroidism shows a low or inappropriately normal TSH with low free T4. Thyroid peroxidase antibody positivity raises the likelihood of progression to overt disease.
A 40-year-old reports heartburn and acid regurgitation several times weekly for two months, without dysphagia, weight loss, anemia, or GI bleeding. What is the most appropriate diagnostic approach?
- Obtain ambulatory pH monitoring as the first step
- Order upper endoscopy before any treatment
- Order a barium swallow to confirm reflux
- Make a clinical diagnosis of GERD based on typical symptoms
Correct answer: Make a clinical diagnosis of GERD based on typical symptoms
A clinical diagnosis of GERD can be made based on typical heartburn and regurgitation in the absence of alarm features. An empiric trial of acid suppression is both diagnostic and therapeutic in this setting. Endoscopy is reserved for alarm symptoms such as dysphagia, weight loss, bleeding, or anemia, and pH monitoring is used when the diagnosis remains uncertain or before anti-reflux surgery.
A 7-year-old presents with sudden fever, sore throat, tender anterior cervical lymph nodes, and tonsillar exudates, with no cough or rhinorrhea. Which step best confirms group A streptococcal pharyngitis before prescribing antibiotics?
- Rapid antigen detection test, with throat culture if negative
- A monospot heterophile antibody test
- Serum C-reactive protein level
- Empiric antibiotics based on clinical features alone
Correct answer: Rapid antigen detection test, with throat culture if negative
A rapid antigen detection test, with a backup throat culture if negative, best confirms group A streptococcal pharyngitis in a child. Clinical features overlap with viral causes, so testing is required; in children and adolescents a negative rapid test should be confirmed by culture because of the higher disease prevalence and rheumatic fever risk. A monospot screens for mononucleosis, not strep.
A nurse practitioner applies the modified Centor (McIsaac) score to a patient with sore throat. Which set of features each contributes a point toward the likelihood of group A streptococcal pharyngitis?
- Oral ulcers, drooling, trismus, muffled voice
- Tonsillar exudate, tender anterior cervical nodes, fever, absence of cough
- Cough, rhinorrhea, conjunctivitis, hoarseness
- Posterior cervical adenopathy, splenomegaly, fatigue, rash
Correct answer: Tonsillar exudate, tender anterior cervical nodes, fever, absence of cough
Tonsillar exudate, tender anterior cervical lymph nodes, fever, and absence of cough each add a point in the Centor/McIsaac scoring, with age adjustment added in the modified version. These criteria identify patients more likely to have group A strep and therefore most appropriate for testing. Cough, rhinorrhea, and conjunctivitis instead suggest a viral cause, and posterior adenopathy with splenomegaly points toward mononucleosis.
A 4-year-old has ear pain and fever. Which otoscopic finding most strongly confirms acute otitis media rather than otitis media with effusion?
- A retracted tympanic membrane with a normal light reflex
- An air-fluid level behind a translucent, mobile drum
- A bulging, opacified tympanic membrane with impaired mobility
- Cerumen impaction obscuring the canal
Correct answer: A bulging, opacified tympanic membrane with impaired mobility
A bulging, opacified tympanic membrane with impaired mobility most strongly confirms acute otitis media, reflecting middle-ear inflammation and purulent effusion under pressure. An air-fluid level behind a translucent, mobile drum indicates otitis media with effusion without acute infection, and a retracted membrane with a normal light reflex is not diagnostic of acute disease. Bulging is the single most reliable sign of acute otitis media.
A 55-year-old presents with fever, productive cough, pleuritic chest pain, and focal crackles with bronchial breath sounds at the right base. Which test best confirms community-acquired pneumonia in the outpatient setting?
- Resting pulse oximetry alone
- Procalcitonin level alone
- Sputum Gram stain alone
- Chest radiograph demonstrating a new infiltrate
Correct answer: Chest radiograph demonstrating a new infiltrate
A chest radiograph demonstrating a new pulmonary infiltrate best confirms community-acquired pneumonia, providing the radiographic evidence that, combined with compatible signs and symptoms, establishes the diagnosis. Pulse oximetry assesses severity but not the presence of consolidation, and sputum studies and procalcitonin support but do not by themselves confirm pneumonia.
A 68-year-old has an estimated glomerular filtration rate of 38 mL/min/1.73 m2 confirmed on repeat testing three months apart. Using KDIGO GFR categories, which stage of chronic kidney disease does this represent?
- G3a
- G3b
- G2
- G4
Correct answer: G3b
An eGFR of 38 mL/min/1.73 m2 corresponds to category G3b (30 to 44). KDIGO defines G1 as 90 or higher, G2 as 60 to 89, G3a as 45 to 59, G3b as 30 to 44, G4 as 15 to 29, and G5 as below 15. Chronic kidney disease requires that the abnormality persist for at least three months, which this case satisfies.
When staging chronic kidney disease, KDIGO classifies a patient by cause, GFR category, and a third dimension. Which finding defines that third dimension?
- Blood pressure category
- Serum potassium level
- Hemoglobin concentration
- Urine albumin-to-creatinine ratio
Correct answer: Urine albumin-to-creatinine ratio
The urine albumin-to-creatinine ratio defines the albuminuria dimension of the KDIGO CGA staging, with A1 below 30 mg/g, A2 30 to 300 mg/g, and A3 above 300 mg/g. Combining cause, GFR category, and albuminuria category refines prognosis better than GFR alone. Potassium, blood pressure, and hemoglobin reflect complications or comorbidities rather than the staging axes themselves.
A microcytic anemia workup returns a low serum ferritin, low serum iron, high total iron-binding capacity, and low transferrin saturation. Which diagnosis do these iron studies best support?
- Anemia of chronic disease
- Thalassemia minor
- Sideroblastic anemia
- Iron deficiency anemia
Correct answer: Iron deficiency anemia
Iron deficiency anemia is supported by low ferritin, low serum iron, high total iron-binding capacity, and low transferrin saturation. Depleted stores drive ferritin down and raise TIBC as the body upregulates transferrin to capture scarce iron. Anemia of chronic disease classically shows normal-to-high ferritin with a low or normal TIBC, the opposite of this iron-deficient pattern.
Two patients have microcytic anemia. Which laboratory contrast best distinguishes iron deficiency anemia from anemia of chronic disease?
- Positive direct Coombs in iron deficiency versus negative in anemia of chronic disease
- High reticulocyte count in iron deficiency versus low in anemia of chronic disease
- Elevated bilirubin in iron deficiency versus normal in anemia of chronic disease
- Low ferritin with high TIBC in iron deficiency versus normal-to-high ferritin with low TIBC in anemia of chronic disease
Correct answer: Low ferritin with high TIBC in iron deficiency versus normal-to-high ferritin with low TIBC in anemia of chronic disease
The best distinguishing contrast is low ferritin with high TIBC in iron deficiency versus normal-to-high ferritin with low TIBC in anemia of chronic disease. In chronic inflammation, hepcidin traps iron in stores, raising ferritin while reducing iron availability and TIBC. Reticulocyte counts are typically low in both, and Coombs positivity and elevated bilirubin point toward hemolysis rather than either microcytic anemia.
A 48-year-old reports several weeks of intermittent right-upper-quadrant pain after fatty meals, with no jaundice or fever. When building a differential diagnosis for this abdominal pain, which condition is the most likely leading consideration?
- Symptomatic cholelithiasis (biliary colic)
- Acute appendicitis
- Renal colic
- Diverticulitis
Correct answer: Symptomatic cholelithiasis (biliary colic)
Symptomatic cholelithiasis, or biliary colic, is the most likely leading consideration for postprandial right-upper-quadrant pain triggered by fatty meals without fever or jaundice. Localizing pain to the right upper quadrant and relating it to fatty meals helps prioritize the differential. Appendicitis and diverticulitis typically cause lower-quadrant pain, and renal colic radiates to the flank and groin with hematuria.
A previously healthy 35-year-old has a dry cough for 6 days with rhinorrhea and a low-grade fever, and a clear chest exam. Which is the most likely diagnosis when forming a differential for this acute cough?
- Community-acquired pneumonia
- Chronic obstructive pulmonary disease
- Congestive heart failure
- Acute viral upper respiratory infection
Correct answer: Acute viral upper respiratory infection
An acute viral upper respiratory infection is the most likely diagnosis for a cough lasting under three weeks with coryza, low-grade fever, and a clear chest exam. Acute cough is most often self-limited and viral. Pneumonia would more often produce focal findings and higher fever, while COPD and heart failure cause chronic or recurrent cough with other characteristic features.
A nonsmoking 50-year-old with no ACE inhibitor use has a cough persisting more than 8 weeks, a normal chest radiograph, and no red-flag features. Which three conditions represent the most common causes to prioritize in the differential for chronic cough?
- Heart failure, pericarditis, and aortic dissection
- Lung cancer, tuberculosis, and sarcoidosis
- Pulmonary embolism, pneumothorax, and pleural effusion
- Upper airway cough syndrome, asthma, and gastroesophageal reflux disease
Correct answer: Upper airway cough syndrome, asthma, and gastroesophageal reflux disease
Upper airway cough syndrome, asthma, and gastroesophageal reflux disease are the most common causes of chronic cough in a nonsmoker with a normal chest film and no red flags, so they head the differential. These three account for the large majority of such cases. Malignancy, infection, and cardiovascular causes are considered when red flags or abnormal imaging are present.
A 60-year-old with diabetes and hypertension reports substernal chest pressure radiating to the left arm with exertion, relieved by rest. When prioritizing the differential diagnosis for chest pain, which life-threatening cause should be evaluated first?
- Acute coronary syndrome
- Costochondritis
- Gastroesophageal reflux disease
- Anxiety-related chest pain
Correct answer: Acute coronary syndrome
Acute coronary syndrome should be evaluated first because it is the most immediately life-threatening cause of exertional chest pressure radiating to the arm in a patient with cardiac risk factors. Prioritizing differentials means ruling out the most dangerous and probable diagnoses before benign ones. Costochondritis, reflux, and anxiety are considered only after a cardiac emergency is excluded.
A 28-year-old has a unilateral throbbing headache with photophobia, nausea, and an aura of flashing lights lasting under an hour, with a normal neurologic exam. Which diagnosis best fits when developing the differential for this headache?
- Cluster headache
- Subarachnoid hemorrhage
- Bacterial meningitis
- Migraine with aura
Correct answer: Migraine with aura
Migraine with aura best fits a recurrent unilateral throbbing headache with photophobia, nausea, and a brief reversible visual aura in a patient with a normal exam. Recognizing the classic pattern lets the clinician prioritize the most likely benign diagnosis while remaining alert for red flags. A thunderclap onset would raise concern for subarachnoid hemorrhage, and fever with neck stiffness would suggest meningitis.
When a nurse practitioner develops and prioritizes a differential diagnosis after gathering the history and exam, which principle best guides ordering the list?
- List only the single most statistically common condition
- Order the list alphabetically to avoid bias
- Rank diagnoses by both likelihood and the danger of missing them
- Prioritize the diagnosis the patient suspects
Correct answer: Rank diagnoses by both likelihood and the danger of missing them
The differential should be ranked by both the likelihood of each diagnosis and the consequences of missing a dangerous one, so high-risk conditions are excluded even when less probable. This balances probability with safety, the core of building a useful differential. Listing only the most common condition or relying on the patient's suspicion risks overlooking serious, treatable disease.
A 48-year-old man with no prior cardiovascular disease has a fasting lipid panel showing total cholesterol 248 mg/dL, triglycerides 180 mg/dL, and HDL 40 mg/dL. The nurse practitioner wants to record the value most useful for capturing all atherogenic, apolipoprotein-B-containing lipoproteins when triglycerides are elevated. Which calculated value should be documented?
- Total-cholesterol-to-HDL ratio of 6.2
- Non-HDL cholesterol of 208 mg/dL
- LDL cholesterol estimated by the Friedewald equation only
- VLDL cholesterol of 36 mg/dL
Non-HDL cholesterol of 208 mg/dL is the value to document. Non-HDL is calculated simply as total cholesterol minus HDL (248 minus 40), so it requires no fasting state and stays accurate when triglycerides are high, capturing every atherogenic apolipoprotein-B particle including LDL, VLDL, and remnants. Friedewald-estimated LDL becomes unreliable as triglycerides rise and underestimates risk, the cholesterol ratio is a derived index rather than a measured atherogenic burden, and isolated VLDL does not represent the full atherogenic pool. Current ACC/AHA cholesterol guidance specifically favors non-HDL as a robust secondary diagnostic marker of cardiovascular risk.
A 29-year-old woman at 26 weeks of gestation has no diabetes history and undergoes a one-step 75-gram oral glucose tolerance test after an overnight fast. Her values are fasting 96 mg/dL, one-hour 188 mg/dL, and two-hour 145 mg/dL. Using current ADA diagnostic thresholds, which interpretation is correct?
- Only overt diabetes can be diagnosed in pregnancy, so this test is not interpretable
- Gestational diabetes is excluded because the fasting value is below 100 mg/dL
- Two abnormal values are required, so this result is normal
- Gestational diabetes is diagnosed because the one-hour value meets or exceeds 180 mg/dL
Gestational diabetes is diagnosed because the one-hour value meets or exceeds 180 mg/dL. On the one-step 75-gram test, the ADA thresholds are fasting 92 mg/dL or higher, one-hour 180 mg/dL or higher, and two-hour 153 mg/dL or higher, and a single value at or above any cutoff establishes the diagnosis. This patient's one-hour 188 mg/dL exceeds the threshold even though her fasting and two-hour values are below their cutoffs. The fasting value being under 100 is irrelevant since the cutoff is 92, gestational diabetes is a valid diagnosis distinct from overt diabetes, and only one abnormal value is needed on the one-step approach.
A 67-year-old with progressive exertional dyspnea, orthopnea, and bilateral ankle edema has clear suspicion of heart failure. The nurse practitioner orders a natriuretic peptide and an echocardiogram. The NT-proBNP returns at 1,850 pg/mL and the ejection fraction is 55 percent with evidence of impaired relaxation. Which diagnosis is best supported?
- The elevated peptide rules out any cardiac cause
- Heart failure with preserved ejection fraction
- Pulmonary embolism rather than heart failure
- Heart failure with reduced ejection fraction
Heart failure with preserved ejection fraction is best supported. The clinical syndrome plus a clearly elevated NT-proBNP confirms heart failure, and an ejection fraction of 55 percent (50 percent or higher) with diastolic dysfunction defines the preserved-ejection-fraction phenotype. A reduced-ejection-fraction diagnosis would require an EF of 40 percent or less, the typical congestive findings and echo point to a cardiac cause rather than pulmonary embolism, and a high natriuretic peptide supports rather than excludes heart failure. Combining the natriuretic peptide with echocardiographic EF is the standard approach to establishing the heart failure subtype.
A 72-year-old reports palpitations and lightheadedness. The 12-lead EKG shows an irregularly irregular rhythm with absent discrete P waves and a fibrillatory baseline at a ventricular rate of 128. Which diagnosis does this tracing establish?
- Atrial flutter with fixed 2:1 conduction
- Atrial fibrillation with rapid ventricular response
- Third-degree atrioventricular block
- Sinus tachycardia
Atrial fibrillation with rapid ventricular response is the diagnosis. The hallmark EKG findings are an irregularly irregular ventricular rhythm, the absence of organized P waves, and a chaotic fibrillatory baseline, exactly as described, with the rate above 100 defining the rapid ventricular response. Atrial flutter produces a regular sawtooth pattern, sinus tachycardia has upright P waves before every regular QRS complex, and complete heart block shows P waves marching independently of the QRS with a slow escape rhythm. Recognizing the irregularly irregular rhythm without P waves is the key to diagnosing atrial fibrillation.
A 58-year-old with crushing substernal chest pain has a 12-lead EKG demonstrating ST-segment elevation of 2 mm in leads II, III, and aVF. Troponin is pending. Which diagnosis and territory are correctly identified?
- Non-ST-elevation myocardial infarction of the lateral wall
- Anterior ST-elevation myocardial infarction
- Pericarditis with diffuse ST elevation
- Inferior ST-elevation myocardial infarction
Inferior ST-elevation myocardial infarction is correctly identified. ST elevation localized to leads II, III, and aVF reflects injury to the inferior wall, and meeting the ST-elevation threshold establishes a STEMI regardless of the pending troponin because the diagnosis is electrocardiographic and time-critical. Anterior STEMI shows elevation in the precordial V leads, NSTEMI by definition lacks persistent ST elevation, and pericarditis produces diffuse rather than regionally localized ST elevation often with PR depression. Mapping ST elevation to a contiguous lead group is the essential skill for diagnosing and localizing a STEMI.
A 19-year-old college student has one week of severe sore throat, marked fatigue, fever, and tender posterior cervical lymphadenopathy, and the exam reveals splenomegaly. A rapid streptococcal test is negative. Which test best confirms the suspected diagnosis?
- Antinuclear antibody panel
- Throat culture for group A streptococcus
- Heterophile (monospot) antibody test
- Chest radiograph
The heterophile (monospot) antibody test best confirms the diagnosis. Posterior cervical lymphadenopathy, profound fatigue, pharyngitis, and splenomegaly in a young adult point to infectious mononucleosis from Epstein-Barr virus, and the heterophile antibody test is the standard confirmatory study, supported when needed by a lymphocyte-predominant complete blood count with atypical lymphocytes. A throat culture targets a different pathogen already made unlikely by the negative rapid test and the mononucleosis picture, antinuclear antibodies screen for autoimmune disease, and a chest film does not address pharyngitis. Pairing the clinical syndrome with the heterophile test is how mononucleosis is established.
A 34-year-old recent immigrant with no symptoms and a normal chest radiograph is screened for tuberculosis. The interferon-gamma release assay is positive. Which diagnosis does this result support?
- Active pulmonary tuberculosis requiring isolation
- Latent tuberculosis infection
- Prior BCG vaccination reaction with no infection
- A false result that must be confirmed with sputum smear
Latent tuberculosis infection is supported. A positive interferon-gamma release assay indicates infection with Mycobacterium tuberculosis, and when the person is asymptomatic with a normal chest radiograph, the diagnosis is the latent rather than active form. Active disease requires symptoms or radiographic or microbiologic evidence of disease, which are absent here, so isolation and sputum testing are not indicated by this picture. The interferon-gamma assay is unaffected by prior BCG vaccination, which is one of its advantages over the skin test. Distinguishing latent from active infection by combining the immunologic test with symptoms and imaging is the core diagnostic step.
An asymptomatic 40-year-old has hepatitis B serologies showing a positive surface antibody, a positive core antibody, and a negative surface antigen. Which interpretation is correct?
- Acute hepatitis B infection
- Resolved past hepatitis B infection with immunity
- Chronic active hepatitis B infection
- Immunity from vaccination only
Resolved past hepatitis B infection with immunity is correct. A positive surface antibody indicates immunity, the positive core antibody indicates prior natural exposure to the virus, and a negative surface antigen shows the virus is no longer present, a pattern that defines a resolved infection. Acute and chronic infection both require a positive surface antigen, which is absent here. Vaccine-derived immunity produces a positive surface antibody with a negative core antibody, because the vaccine contains only surface antigen. Reading the surface antigen, surface antibody, and core antibody together is the standard way to interpret hepatitis B status.
A 26-year-old woman reports vaginal discharge. Examination shows a thin, off-white homogeneous discharge with a vaginal pH of 5.0, a positive whiff test on adding potassium hydroxide, and clue cells on microscopy. Which diagnosis do these findings establish?
- Trichomoniasis
- Bacterial vaginosis
- Atrophic vaginitis
- Vulvovaginal candidiasis
Bacterial vaginosis is established. The Amsel criteria diagnose bacterial vaginosis when at least three of four features are present, and this patient has a thin homogeneous discharge, a vaginal pH above 4.5, a positive whiff test, and clue cells, satisfying all four. Candidiasis typically causes a thick white discharge with a normal pH and pruritus, trichomoniasis produces a frothy discharge with motile trichomonads and often a higher pH but no clue cells, and atrophic vaginitis occurs with estrogen deficiency and lacks clue cells and a positive whiff test. Applying the Amsel criteria is the standard office method for diagnosing bacterial vaginosis.
A 65-year-old postmenopausal woman with no fragility fractures undergoes a dual-energy X-ray absorptiometry scan that reports a femoral neck T-score of negative 2.6. Which diagnosis does this measurement establish?
- Osteoporosis
- Osteomalacia
- Osteopenia (low bone mass)
- Normal bone density
Osteoporosis is established. By World Health Organization densitometric criteria, a T-score of negative 2.5 or lower at the spine, total hip, or femoral neck defines osteoporosis, and this patient's negative 2.6 meets that cutoff. Osteopenia corresponds to a T-score between negative 1.0 and negative 2.5, a normal result is negative 1.0 or higher, and osteomalacia is a defect in bone mineralization usually from vitamin D deficiency that is diagnosed clinically and biochemically rather than by a T-score. Reading the T-score against the standardized thresholds is how a densitometric osteoporosis diagnosis is made.
A 35-year-old with palpitations, heat intolerance, unintentional weight loss, and a fine tremor has a suppressed TSH with an elevated free T4. Which additional finding would most specifically confirm Graves disease as the cause of the hyperthyroidism?
- A positive heterophile antibody test
- An elevated total cholesterol level
- A low radioactive iodine uptake scan
- Positive thyroid-stimulating immunoglobulin (TSH receptor antibody)
A positive thyroid-stimulating immunoglobulin, a TSH receptor antibody, would most specifically confirm Graves disease. The biochemical pattern of a suppressed TSH with an elevated free T4 confirms primary hyperthyroidism, and a positive TSH receptor antibody identifies the autoimmune Graves mechanism that drives the gland. Elevated cholesterol is associated with hypothyroidism, not hyperthyroidism, a low radioactive iodine uptake would suggest thyroiditis rather than Graves, which shows high diffuse uptake, and a heterophile antibody test screens for mononucleosis. Adding the receptor antibody to the thyroid function panel is the key step in establishing Graves disease.
A 7-year-old has two weeks of clear watery rhinorrhea, sneezing, itchy watery eyes, and nasal congestion that recur every spring, with no fever. Examination shows pale, boggy nasal turbinates and a transverse nasal crease. Which diagnosis best fits this presentation?
- Choanal atresia
- Allergic rhinitis
- Acute bacterial sinusitis
- Acute viral upper respiratory infection
Allergic rhinitis best fits. The combination of seasonal recurrence, ocular and nasal itching, sneezing, an absence of fever, pale boggy turbinates, and a transverse nasal crease from chronic upward rubbing is characteristic of an allergic rather than infectious process. A viral upper respiratory infection is self-limited over about a week and often has a low-grade fever and sore throat rather than seasonal pruritus, bacterial sinusitis features purulent discharge with facial pain and persistent or worsening symptoms, and choanal atresia presents in infancy with obstruction. Recognizing the itch, seasonality, and boggy pale mucosa is how allergic rhinitis is diagnosed clinically.
A nurse practitioner is developing a plan of care for a 58-year-old patient with newly diagnosed hypertension. Which step best reflects a patient-centered approach to creating the plan?
- Eliciting the patient's daily routine, values, and treatment preferences before setting blood pressure goals together
- Providing a printed low-sodium diet handout and ending the visit
- Prescribing a thiazide diuretic and scheduling a 3-month recheck before any discussion
- Referring the patient to a cardiologist to determine the plan
Correct answer: Eliciting the patient's daily routine, values, and treatment preferences before setting blood pressure goals together
Eliciting the patient's daily routine, values, and preferences before mutually setting goals is the hallmark of a patient-centered plan of care. Patient-centered planning means goals and interventions are negotiated WITH the patient rather than dictated to them, which improves adherence and outcomes. Simply prescribing or handing out a diet sheet without shared goal-setting is provider-driven, not patient-centered.
During care planning for a 45-year-old man whose 10-year ASCVD risk is 14% and whose blood pressure is consistently 134/84 mm Hg, which planned intervention aligns with the 2017 ACC/AHA hypertension guideline?
- Initiating antihypertensive pharmacotherapy in addition to lifestyle modification
- Recommending only home blood pressure monitoring without any intervention
- Lifestyle modification alone with recheck in 6 months
- Deferring all treatment until blood pressure reaches 140/90 mm Hg
Correct answer: Initiating antihypertensive pharmacotherapy in addition to lifestyle modification
Initiating antihypertensive pharmacotherapy along with lifestyle modification is correct for stage 1 hypertension (130-139/80-89 mm Hg) when the 10-year ASCVD risk is 10% or greater. The ACC/AHA guideline reserves lifestyle-only management for stage 1 patients with ASCVD risk below 10%; at 14% risk, drug therapy is indicated. Waiting for 140/90 applies only to low-risk patients.
A nurse practitioner is planning preventive care for an average-risk 46-year-old patient with no symptoms and no family history of colon cancer. Which screening should be scheduled per current USPSTF recommendations?
- Colorectal cancer screening should be initiated now
- No colorectal screening is indicated until age 50
- Colonoscopy every 2 years starting immediately
- Colorectal screening only if the patient develops symptoms
Correct answer: Colorectal cancer screening should be initiated now
Colorectal cancer screening should be initiated now, because the USPSTF recommends average-risk screening begin at age 45 (Grade B). A 46-year-old who has never been screened is overdue. Modeling showed benefits outweigh harms for average-risk adults beginning at 45, so deferring to 50 or waiting for symptoms is outdated.
When developing a care plan, a nurse practitioner writes the goal 'Patient will walk 20 minutes daily, 5 days per week, and lose 5 pounds within 8 weeks.' This goal best demonstrates which planning principle?
- A medical diagnosis rather than a planning outcome
- A goal written in nursing rather than patient terms
- An outcome that belongs in the evaluation phase only
- A SMART goal that is specific, measurable, and time-bound
Correct answer: A SMART goal that is specific, measurable, and time-bound
This is a SMART goal: specific (walk 20 minutes), measurable (5 days/week, 5 pounds), and time-bound (8 weeks). Effective planning translates broad aims into measurable, time-limited outcomes so progress can be evaluated objectively. A vague aim such as 'patient will exercise more' could not be measured at follow-up.
A nurse practitioner is prioritizing problems in the care plan for a patient who presents with poorly controlled asthma, mild eczema, and an overdue tetanus booster. Which problem should the plan address first?
- The mild eczema
- The overdue tetanus booster
- All three problems should be deferred to the next visit
- The poorly controlled asthma
Correct answer: The poorly controlled asthma
The poorly controlled asthma should be prioritized first because it poses the greatest threat to airway, breathing, and immediate safety. Care planning uses prioritization frameworks (such as the ABCs and Maslow's hierarchy) so that the most physiologically urgent or life-threatening problem is addressed before lower-acuity or routine preventive items.
A nurse practitioner managing a 62-year-old with type 2 diabetes and established atherosclerotic cardiovascular disease is planning pharmacotherapy. Per the ADA Standards of Care, which agent should be incorporated into the plan independent of the A1C?
- A second-generation basal insulin
- An SGLT2 inhibitor or GLP-1 receptor agonist with proven cardiovascular benefit
- A DPP-4 inhibitor
- A sulfonylurea
Correct answer: An SGLT2 inhibitor or GLP-1 receptor agonist with proven cardiovascular benefit
An SGLT2 inhibitor or GLP-1 receptor agonist with demonstrated cardiovascular benefit should be included in the plan independent of A1C and independent of metformin use for patients with type 2 diabetes and established ASCVD. The ADA bases this on cardiovascular and kidney outcome benefits rather than glycemic control. Sulfonylureas and DPP-4 inhibitors lack these proven cardiovascular benefits.
A nurse practitioner sees a 4-month-old at a well-child visit and is planning the immunization schedule. According to the CDC childhood schedule, which vaccines are due at the 4-month visit for an on-schedule infant?
- MMR, varicella, and hepatitis A
- Tdap and HPV
- DTaP, IPV, Hib, PCV, and rotavirus
- Influenza and meningococcal ACWY only
Correct answer: DTaP, IPV, Hib, PCV, and rotavirus
DTaP, IPV, Hib, PCV, and rotavirus are the vaccines due at the 4-month visit on the CDC childhood immunization schedule. MMR, varicella, and hepatitis A are not given until 12-15 months, and HPV/Tdap/meningococcal ACWY belong to the adolescent schedule. Accurate scheduling is a core planning function in pediatric primary care.
A nurse practitioner identifies that a patient with rheumatoid arthritis has progressive joint deformity and an active inflammatory flare despite maximal first-line therapy. Which planning decision is most appropriate?
- Discontinue all medications and reassess in 1 year
- Refer the patient to a rheumatologist for advanced disease-modifying therapy
- Refer only to physical therapy without specialist involvement
- Continue the current regimen unchanged for another 6 months
Correct answer: Refer the patient to a rheumatologist for advanced disease-modifying therapy
Referral to a rheumatologist for advanced disease-modifying therapy is appropriate because the disease is progressing despite maximal first-line management and falls outside routine primary-care scope. Knowing when to refer to a specialist is a planning competency: refer when the condition exceeds the NP's scope, fails standard therapy, or requires specialized diagnostics or treatment.
While planning care for a 30-year-old woman who wants to become pregnant in the next year, which intervention should the nurse practitioner prioritize in preconception planning?
- Recommending an annual chest radiograph
- Initiating statin therapy for primary prevention
- Starting 400 to 800 micrograms of folic acid daily
- Scheduling a screening colonoscopy
Correct answer: Starting 400 to 800 micrograms of folic acid daily
Starting 400 to 800 micrograms of folic acid daily is the priority in preconception planning to reduce the risk of fetal neural tube defects, which form in the first weeks of pregnancy before many women know they are pregnant. The USPSTF gives daily folic acid supplementation a Grade A recommendation for those planning or capable of pregnancy. Statins are contraindicated in pregnancy.
A nurse practitioner is planning a smoking-cessation strategy for a motivated 50-year-old patient. Which approach reflects evidence-based planning?
- Combining behavioral counseling with FDA-approved pharmacotherapy such as varenicline or nicotine replacement
- Recommending e-cigarettes as the sole long-term cessation method
- Advising the patient to quit abruptly without any support
- Delaying any intervention until the patient develops symptoms
Correct answer: Combining behavioral counseling with FDA-approved pharmacotherapy such as varenicline or nicotine replacement
Combining behavioral counseling with FDA-approved pharmacotherapy such as varenicline or nicotine replacement is the evidence-based plan, as the combination produces higher quit rates than either alone. The USPSTF recommends both behavioral and pharmacologic interventions for adults who use tobacco. E-cigarettes are not an FDA-approved cessation aid.
A nurse practitioner plans annual lung cancer screening for an appropriate patient. Which 55-year-old patient meets the USPSTF criteria for low-dose CT screening?
- A never-smoker with a family history of lung cancer
- A patient with a 25 pack-year history who quit 8 years ago
- A patient with a 10 pack-year history who currently smokes
- A patient with a 20 pack-year history who quit 20 years ago
Correct answer: A patient with a 25 pack-year history who quit 8 years ago
The patient with a 25 pack-year history who quit 8 years ago meets the USPSTF criteria: age 50 to 80, at least a 20 pack-year history, and currently smoking or having quit within the past 15 years. The never-smoker and the 10 pack-year smoker fall short of the pack-year threshold, and the patient who quit 20 years ago is beyond the 15-year window.
When co-creating a care plan with a patient who has limited health literacy, which planning strategy best supports comprehension and shared decision-making?
- Limiting the plan to a single medication with no explanation
- Providing a detailed written plan at a college reading level
- Asking a family member to make decisions on the patient's behalf
- Using teach-back and plain language to confirm the patient understands the agreed plan
Correct answer: Using teach-back and plain language to confirm the patient understands the agreed plan
Using teach-back and plain language to confirm understanding best supports a patient-centered plan for someone with limited health literacy. Teach-back asks the patient to restate the plan in their own words, verifying comprehension and surfacing misunderstandings before the visit ends. Materials written above the patient's reading level undermine shared decision-making.
A nurse practitioner is planning follow-up intervals for a 68-year-old patient with stable, well-controlled hypertension on a single agent. Which monitoring plan is most appropriate?
- No further follow-up once blood pressure is controlled
- Annual visits only, with no home monitoring
- Office visits every week indefinitely
- A follow-up visit in 3 to 6 months with interval home blood pressure monitoring
Correct answer: A follow-up visit in 3 to 6 months with interval home blood pressure monitoring
A follow-up visit in 3 to 6 months with interval home blood pressure monitoring is appropriate for stable, controlled hypertension. Planning includes establishing a realistic monitoring cadence that balances safety with patient burden; weekly visits are excessive and stopping follow-up risks missing loss of control.
A nurse practitioner is planning the management of a 7-year-old with newly diagnosed mild intermittent asthma. According to stepwise asthma guidelines, which is the appropriate controller plan?
- Daily oral corticosteroids
- A daily medium-dose inhaled corticosteroid
- A long-acting beta-agonist used alone
- A short-acting beta-agonist as needed for symptoms, with no daily controller
Correct answer: A short-acting beta-agonist as needed for symptoms, with no daily controller
A short-acting beta-agonist as needed, without a daily controller, is the correct plan for mild intermittent asthma (Step 1). Stepwise planning matches therapy intensity to severity; daily inhaled corticosteroids are reserved for persistent asthma, and a long-acting beta-agonist must never be used as monotherapy because of safety risk.
A nurse practitioner evaluates a 40-year-old with a suspicious 8 mm asymmetric pigmented skin lesion that has changed in color and border. What is the appropriate planning decision?
- Prescribe a topical antifungal and reassess in 2 weeks
- Refer to dermatology for biopsy and evaluation
- Plan cryotherapy in the office at this visit
- Reassure the patient and recheck in 1 year
Correct answer: Refer to dermatology for biopsy and evaluation
Referral to dermatology for biopsy and evaluation is appropriate because a changing, asymmetric pigmented lesion raises concern for melanoma, which requires specialist diagnosis and definitive tissue sampling. Recognizing when a finding exceeds primary-care scope and warrants timely specialist referral is a key planning skill; delaying or empirically treating could allow a malignancy to progress.
A nurse practitioner is establishing goals of care with a 79-year-old with multiple chronic conditions and limited life expectancy. Which planning approach is most appropriate?
- Aligning goals with the patient's stated priorities and quality-of-life preferences
- Focusing exclusively on cancer screening tests
- Applying every disease-specific guideline target aggressively
- Deferring all decisions to the patient's adult children
Correct answer: Aligning goals with the patient's stated priorities and quality-of-life preferences
Aligning goals with the patient's stated priorities and quality-of-life preferences is most appropriate for an older adult with limited life expectancy. Patient-centered planning in geriatrics often means deintensifying tight disease targets and aggressive screening in favor of comfort, function, and what matters most to the patient. Rigidly applying every guideline target can cause harm in this population.
A nurse practitioner is planning care for a 25-year-old woman starting a combined oral contraceptive. Which baseline assessment is essential to include in the plan before prescribing?
- A baseline electrocardiogram for all patients
- A fasting lipid panel and liver biopsy
- A bone density scan
- Blood pressure measurement and a focused history for thromboembolic risk factors
Correct answer: Blood pressure measurement and a focused history for thromboembolic risk factors
Blood pressure measurement and a focused history for thromboembolic risk factors are essential before prescribing a combined oral contraceptive. Estrogen-containing contraceptives raise venous thromboembolism risk and are contraindicated with uncontrolled hypertension or migraine with aura, so the plan must screen for these. Routine ECG, bone density, or liver biopsy are not required.
A nurse practitioner is planning the depression treatment for an adult who meets DSM-5-TR criteria for major depressive disorder, moderate severity, with no suicidal ideation. Which evidence-based plan is most appropriate as first-line?
- Plan no treatment and recheck in 6 months
- Begin an SSRI and/or evidence-based psychotherapy with a follow-up to assess response
- Immediately refer for electroconvulsive therapy
- Prescribe a benzodiazepine as monotherapy
Correct answer: Begin an SSRI and/or evidence-based psychotherapy with a follow-up to assess response
Beginning an SSRI and/or evidence-based psychotherapy with planned follow-up is the appropriate first-line plan for moderate major depressive disorder. SSRIs and psychotherapy are first-line per practice guidelines, and follow-up within a few weeks is planned to assess response and suicidality. ECT is reserved for severe or refractory cases, and benzodiazepine monotherapy is not a treatment for depression.
A nurse practitioner plans an immunization update for a 65-year-old adult presenting for an annual visit. Which vaccine should the plan include specifically because of the patient's age?
- Pneumococcal vaccination per the current ACIP schedule
- A second dose of MMR
- Rotavirus vaccine
- A booster of the childhood DTaP formulation
Correct answer: Pneumococcal vaccination per the current ACIP schedule
Pneumococcal vaccination per the current ACIP schedule should be planned, as it is recommended for all adults at age 65 and older. MMR is not boosted routinely at this age, rotavirus is an infant vaccine, and adults receive Tdap (not the pediatric DTaP) for tetanus boosting. Age-appropriate immunization scheduling is a core planning task.
A nurse practitioner is developing a care plan for a 12-year-old with obesity (BMI at the 97th percentile). Which goal best reflects appropriate, family-centered planning?
- A rapid weight-loss goal of 2 pounds per week through caloric restriction
- Prescription of an appetite suppressant as the primary intervention
- Gradual improvement in eating and activity habits with family involvement and BMI tracking over time
- Immediate referral for bariatric surgery
Correct answer: Gradual improvement in eating and activity habits with family involvement and BMI tracking over time
Gradual improvement in eating and activity habits with family involvement and BMI tracking is the appropriate plan for pediatric obesity. Family-centered behavioral change is first-line; rapid weight-loss targets are unsafe in growing children, and surgery or pharmacotherapy are reserved for specific severe cases after lifestyle intervention. Involving the family is essential because children depend on the home food environment.
A nurse practitioner is planning anticoagulation for a 70-year-old with newly diagnosed nonvalvular atrial fibrillation. Which tool should guide the planning decision about anticoagulation?
- The MELD score
- The Wells score for pulmonary embolism
- The CHA2DS2-VASc score to estimate stroke risk
- The CURB-65 score
Correct answer: The CHA2DS2-VASc score to estimate stroke risk
The CHA2DS2-VASc score should guide anticoagulation planning in nonvalvular atrial fibrillation by estimating annual stroke risk to determine whether anticoagulation is warranted. Risk-stratification tools are integral to evidence-based planning. The MELD, Wells, and CURB-65 scores apply to liver disease, pulmonary embolism, and pneumonia respectively, not atrial fibrillation stroke risk.
A nurse practitioner is planning care for a patient with newly diagnosed chronic kidney disease whose estimated GFR has rapidly declined and who has refractory hyperkalemia. What is the most appropriate referral decision?
- Defer referral until the patient requires dialysis
- Refer to nephrology for co-management
- Continue routine primary-care management without referral
- Refer to cardiology
Correct answer: Refer to nephrology for co-management
Referral to nephrology for co-management is appropriate given the rapidly declining GFR and refractory hyperkalemia, both of which signal complex disease beyond routine primary-care management. Planning includes recognizing red flags that warrant specialist co-management early; waiting until dialysis is needed delays interventions that could slow progression and manage complications.
A nurse practitioner is planning gestational diabetes screening for a healthy pregnant patient with no risk factors. At what point in pregnancy should routine screening be planned?
- Between 24 and 28 weeks of gestation
- At 36 weeks of gestation
- Only if the patient develops symptoms of hyperglycemia
- At the first prenatal visit only
Correct answer: Between 24 and 28 weeks of gestation
Routine gestational diabetes screening should be planned between 24 and 28 weeks of gestation for patients without risk factors, when placental hormones most strongly affect glucose tolerance. Early first-trimester screening is reserved for those with risk factors such as obesity or prior gestational diabetes. Scheduling screening at the correct window is a prenatal planning competency.
A nurse practitioner is planning therapy for a patient with stage 1 hypertension and a comorbid diagnosis of type 2 diabetes with albuminuria. Which antihypertensive class should the plan favor?
- A peripheral alpha-blocker
- A beta-blocker
- A nondihydropyridine calcium channel blocker
- An ACE inhibitor or angiotensin receptor blocker
Correct answer: An ACE inhibitor or angiotensin receptor blocker
An ACE inhibitor or angiotensin receptor blocker should be favored because these agents provide renal protection and reduce albuminuria progression in diabetic kidney disease. Compelling-indication planning matches the drug class to comorbidities; beta-blockers and alpha-blockers are not first-line for this profile. Choosing a class with an evidence-based compelling indication is a planning skill.
A nurse practitioner is establishing the plan of care for a patient who disagrees with the NP's recommended statin therapy and prefers to try lifestyle change first. What is the most patient-centered planning response?
- Discharge the patient from the practice for nonadherence
- Prescribe the statin anyway without the patient's agreement
- Document the shared decision, agree on a lifestyle trial with a defined recheck point, and revisit pharmacotherapy then
- Refuse to continue care unless the patient accepts the statin
Correct answer: Document the shared decision, agree on a lifestyle trial with a defined recheck point, and revisit pharmacotherapy then
Documenting the shared decision and agreeing on a lifestyle trial with a defined recheck point reflects patient-centered planning that respects autonomy while keeping a safety follow-up. Shared decision-making negotiates a plan the patient will actually follow and builds in a checkpoint to reassess. Coercing or dismissing the patient violates patient-centered principles.
A nurse practitioner is planning osteoporosis screening. Which patient should have bone mineral density (DXA) testing scheduled per USPSTF recommendations?
- A 30-year-old man
- A 66-year-old woman
- A 67-year-old man with no risk factors
- A 45-year-old woman with no risk factors
Correct answer: A 66-year-old woman
A 66-year-old woman should have DXA scheduled, because the USPSTF recommends bone density screening for osteoporosis in women aged 65 and older. Routine screening of men and of younger women without risk factors is not recommended. Knowing the age-based screening trigger is essential for accurate preventive-care planning.
A nurse practitioner is planning care for a child whose immunizations are behind because the family missed several visits. What is the most appropriate planning approach?
- Administer only the influenza vaccine and defer the rest indefinitely
- Restart the entire vaccine series from the beginning
- Use the CDC catch-up immunization schedule to resume from where the child left off
- Wait until the next well-child visit to address it
Correct answer: Use the CDC catch-up immunization schedule to resume from where the child left off
Using the CDC catch-up immunization schedule to resume from where the child left off is correct; interrupted series do not need to be restarted. The catch-up schedule specifies minimum intervals to bring a child up to date efficiently. Restarting series wastes doses and delays protection, and deferring leaves the child unprotected.
A nurse practitioner is planning care for a 55-year-old with newly diagnosed stable angina and a positive stress test indicating multivessel disease. What referral plan is appropriate?
- Manage entirely in primary care with medication titration
- Refer to pulmonology
- Refer to cardiology for further evaluation and possible revascularization
- No referral; reassess symptoms in 1 year
Correct answer: Refer to cardiology for further evaluation and possible revascularization
Referral to cardiology for further evaluation and possible revascularization is appropriate because multivessel disease on stress testing requires specialized assessment and intervention beyond primary-care scope. Planning includes recognizing high-risk findings that warrant prompt specialist referral; delaying could risk a cardiac event.
A nurse practitioner is planning lipid management for a 60-year-old with clinical ASCVD. According to the ACC/AHA cholesterol guideline, what should the plan prioritize?
- A low-intensity statin
- A bile acid sequestrant as monotherapy
- No statin because the patient already has ASCVD
- High-intensity statin therapy
Correct answer: High-intensity statin therapy
High-intensity statin therapy should be prioritized for a patient with established clinical ASCVD, because secondary-prevention guidelines call for the greatest LDL lowering in this highest-risk group. Low-intensity statins or non-statin monotherapy do not achieve the recommended risk reduction. Matching statin intensity to the patient's risk category is an evidence-based planning decision.
A nurse practitioner is creating a plan of care and wants to ensure goals are realistic for a patient with a busy work schedule and financial constraints. Which planning action best individualizes the plan?
- Omitting goal-setting because the patient is too busy
- Tailoring goals and interventions to the patient's resources, schedule, and barriers
- Choosing the most aggressive regimen regardless of cost
- Setting the same standardized goals used for every patient
Correct answer: Tailoring goals and interventions to the patient's resources, schedule, and barriers
Tailoring goals and interventions to the patient's resources, schedule, and barriers individualizes the plan and improves the likelihood of adherence. Patient-centered planning accounts for real-world constraints such as cost and time so that the plan is achievable. Standardized or maximally aggressive plans that ignore the patient's context often fail.
A nurse practitioner is planning cervical cancer screening for a healthy 30-year-old woman with no prior abnormal results. Which schedule aligns with current guidelines?
- No screening until age 40
- Pap cytology every year
- Primary HPV testing, or co-testing, or cytology at the recommended interval for her age group
- Colposcopy every 3 years
Correct answer: Primary HPV testing, or co-testing, or cytology at the recommended interval for her age group
Primary HPV testing, or co-testing, or cytology at the guideline interval is the appropriate plan for a 30-year-old; for ages 30 to 65 acceptable options include HPV testing every 5 years, co-testing every 5 years, or cytology every 3 years. Annual cytology is no longer recommended, and colposcopy is a diagnostic, not screening, procedure.
A nurse practitioner is planning care for an 80-year-old taking nine medications, several of which are on the Beers Criteria list. Which planning intervention is most appropriate?
- Continue all medications since the patient is stable
- Plan a structured medication review and deprescribing of potentially inappropriate medications
- Add additional medications to treat side effects
- Refer to a specialist for each individual medication
Correct answer: Plan a structured medication review and deprescribing of potentially inappropriate medications
Planning a structured medication review and deprescribing of potentially inappropriate medications is appropriate for an older adult with polypharmacy and Beers Criteria medications. Deprescribing reduces adverse drug events, falls, and interactions. Adding more drugs to treat side effects creates a prescribing cascade and worsens polypharmacy.
A nurse practitioner is planning the prenatal visit schedule for a patient with an uncomplicated pregnancy. Which schedule reflects standard prenatal care planning?
- Weekly visits throughout the entire pregnancy
- Visits roughly every 4 weeks until 28 weeks, every 2 weeks until 36 weeks, then weekly until delivery
- Visits only in the third trimester
- A single visit at the start and one at delivery
Correct answer: Visits roughly every 4 weeks until 28 weeks, every 2 weeks until 36 weeks, then weekly until delivery
Visits roughly every 4 weeks until 28 weeks, every 2 weeks until 36 weeks, then weekly until delivery is the standard prenatal schedule for an uncomplicated pregnancy. This cadence intensifies monitoring as risks rise near term. Scheduling appropriate visit intervals is a core prenatal planning function.
A nurse practitioner is planning care for a patient with a chief complaint of fatigue and is constructing measurable outcomes. Which is an appropriately written patient outcome for the plan?
- Fatigue secondary to iron deficiency anemia
- Administer a complete blood count
- Patient will report improved energy and resume usual activities within 4 weeks of treatment
- Educate the patient about iron-rich foods
Correct answer: Patient will report improved energy and resume usual activities within 4 weeks of treatment
'Patient will report improved energy and resume usual activities within 4 weeks of treatment' is an appropriately written outcome because it is patient-centered, measurable, and time-bound. Ordering a CBC and providing education are interventions, and the anemia statement is a diagnosis. Planning distinguishes outcomes (what the patient will achieve) from interventions and diagnoses.
A nurse practitioner is planning management for a patient with type 2 diabetes whose individualized A1C goal needs to be set. Which factor most appropriately leads to a less stringent A1C target (such as below 8 percent)?
- A young, healthy patient newly diagnosed
- Advanced age with significant comorbidities and a history of severe hypoglycemia
- Long life expectancy with no complications
- Strong patient motivation and low hypoglycemia risk
Correct answer: Advanced age with significant comorbidities and a history of severe hypoglycemia
Advanced age with significant comorbidities and a history of severe hypoglycemia appropriately leads to a less stringent A1C target. The ADA individualizes glycemic goals: tighter targets for healthy patients with long life expectancy, and looser targets when the risks of intensive control (especially hypoglycemia) outweigh benefits. Individualizing the goal is a planning competency.
A nurse practitioner is planning care for a patient who screens positive for unhealthy alcohol use on the AUDIT-C. What is the most appropriate next planning step in primary care?
- Prescribing disulfiram at the same visit without further assessment
- Brief intervention with motivational counseling and a follow-up plan
- No action unless the patient requests help
- Immediate inpatient detoxification for all positive screens
Correct answer: Brief intervention with motivational counseling and a follow-up plan
Brief intervention with motivational counseling and a planned follow-up is the appropriate next step after a positive AUDIT-C in primary care. The USPSTF supports screening and brief behavioral counseling for unhealthy alcohol use. Not every positive screen requires inpatient detox, and pharmacotherapy is planned after assessment of severity and patient goals.
A nurse practitioner is planning care for a 6-year-old with a peanut allergy who has had anaphylaxis. Which element is essential to include in the management plan?
- Daily prophylactic antihistamines as the only intervention
- A plan that avoids any written documentation to reduce anxiety
- An anaphylaxis action plan and a prescription for epinephrine auto-injectors
- Reintroducing small amounts of peanut at home without supervision
Correct answer: An anaphylaxis action plan and a prescription for epinephrine auto-injectors
An anaphylaxis action plan plus a prescription for epinephrine auto-injectors is essential for a child with a history of anaphylaxis. The plan must equip caregivers and school to recognize and treat anaphylaxis immediately. Antihistamines alone do not treat anaphylaxis, and unsupervised home reintroduction of the allergen is dangerous.
A nurse practitioner is planning a fall-prevention strategy for a community-dwelling 78-year-old who reports two falls in the past year. Which evidence-based intervention should the plan prioritize?
- Bed rest to prevent further falls
- A structured exercise program targeting strength and balance, plus a medication and home-hazard review
- Avoiding any physical activity
- Routine wheelchair use for all mobility
Correct answer: A structured exercise program targeting strength and balance, plus a medication and home-hazard review
A structured exercise program targeting strength and balance, combined with a medication and home-hazard review, is the evidence-based fall-prevention plan for an older adult with recurrent falls. Exercise and multifactorial risk reduction reduce fall rates. Bed rest and immobility accelerate deconditioning and actually increase fall risk.
A nurse practitioner is planning depression follow-up using a measurement-based approach. Which tool should be incorporated into the plan to track treatment response over time?
- The Braden Scale
- The APGAR score
- The PHQ-9 administered at follow-up visits
- The Glasgow Coma Scale
Correct answer: The PHQ-9 administered at follow-up visits
The PHQ-9 administered at follow-up visits should be incorporated to track depression treatment response in a measurement-based-care plan. Repeating a validated symptom scale objectively quantifies improvement or worsening and guides treatment adjustments. The Glasgow Coma Scale, Braden Scale, and APGAR score assess consciousness, pressure-injury risk, and newborn status respectively.
A nurse practitioner is planning care for a patient with newly diagnosed hypothyroidism. Which monitoring plan is appropriate after starting levothyroxine?
- Recheck TSH in 1 week
- Recheck TSH only if symptoms recur
- Recheck TSH in approximately 6 to 8 weeks and titrate the dose based on results
- Recheck free T4 daily until normalized
Correct answer: Recheck TSH in approximately 6 to 8 weeks and titrate the dose based on results
Rechecking TSH in approximately 6 to 8 weeks and titrating accordingly is the appropriate plan after starting levothyroxine, because TSH takes that long to reach a new steady state. Checking at 1 week or daily is too soon to reflect the dose change, and waiting for symptoms misses subclinical undertreatment. Scheduling the correct monitoring interval is a planning skill.
A nurse practitioner is planning interprofessional care for a patient with poorly controlled diabetes, depression, and food insecurity. Which planning action best addresses the patient's needs holistically?
- Referring the patient elsewhere and ending involvement
- Managing all issues alone to avoid fragmenting care
- Coordinating referrals to a dietitian, behavioral health, and social work as part of a team-based plan
- Addressing only the diabetes and ignoring the social factors
Correct answer: Coordinating referrals to a dietitian, behavioral health, and social work as part of a team-based plan
Coordinating referrals to a dietitian, behavioral health, and social work as part of a team-based plan best addresses the patient's intertwined medical and social needs. Interprofessional, team-based planning leverages each discipline's expertise and addresses social determinants of health. Ignoring social factors or attempting to manage everything alone leaves key drivers of poor control unaddressed.
A nurse practitioner is planning care for a pregnant patient at 16 weeks whose blood pressure is newly elevated at 150/95 mm Hg with proteinuria. What is the appropriate planning decision?
- Start a routine over-the-counter analgesic and recheck in 2 months
- Refer to maternal-fetal medicine or obstetrics for evaluation of a hypertensive disorder of pregnancy
- Discontinue all prenatal vitamins
- Reassure the patient and continue routine prenatal visits
Correct answer: Refer to maternal-fetal medicine or obstetrics for evaluation of a hypertensive disorder of pregnancy
Referral to maternal-fetal medicine or obstetrics is appropriate because new hypertension with proteinuria in pregnancy raises concern for a hypertensive disorder requiring specialized monitoring and management. Recognizing pregnancy red flags that exceed primary-care scope and arranging timely referral is an essential planning competency; routine follow-up alone would be unsafe.
A nurse practitioner is planning care for an adult presenting for a routine visit who is overdue for several preventive services. Which planning principle helps determine which services to prioritize at this visit?
- Use evidence-based, age- and risk-appropriate guidelines (such as USPSTF) to prioritize high-impact preventive services
- Order every available screening test regardless of indication
- Defer all preventive care to specialists
- Address only the service the patient asks about
Correct answer: Use evidence-based, age- and risk-appropriate guidelines (such as USPSTF) to prioritize high-impact preventive services
Using evidence-based, age- and risk-appropriate guidelines such as the USPSTF to prioritize high-impact preventive services is the correct planning principle. This ensures recommended screenings and immunizations are scheduled based on benefit, not on patient request alone or indiscriminate testing. Ordering everything risks harm and low-value care, while deferring all prevention abandons a core primary-care role.
A nurse practitioner is planning care for a 3-year-old presenting for a well-child visit and wants to incorporate developmental surveillance. According to current guidelines, which planning action is appropriate at this visit?
- Defer all developmental assessment until kindergarten entry
- Refer every child to developmental pediatrics regardless of findings
- Skip developmental screening because the child appears well
- Administer a validated developmental screening tool at the recommended well-child intervals
Correct answer: Administer a validated developmental screening tool at the recommended well-child intervals
Administering a validated developmental screening tool at the recommended well-child intervals is the appropriate plan; standardized developmental screening is recommended at specific well-child visits to detect delays early. Relying on general appearance misses subtle delays, and waiting until kindergarten forfeits early-intervention windows. Building age-appropriate screening into the visit plan is a pediatric planning competency.
A previously healthy 34-year-old woman is diagnosed with stage 2 hypertension (BP 152/96 mmHg confirmed on repeat readings) and has no compelling indications such as diabetes or chronic kidney disease. According to current ACC/AHA guidance, which class of agent is an appropriate first-line pharmacologic choice for her initial therapy?
- An alpha-1 blocker such as doxazosin
- A loop diuretic such as furosemide
- A thiazide or thiazide-like diuretic
- A central alpha-2 agonist such as clonidine
Correct answer: A thiazide or thiazide-like diuretic
A thiazide or thiazide-like diuretic is an appropriate first-line antihypertensive. ACC/AHA guidance lists four first-line classes for primary hypertension without compelling indications: thiazide/thiazide-like diuretics, ACE inhibitors, ARBs, and dihydropyridine calcium channel blockers. Alpha-1 blockers, loop diuretics, and central agonists are not first-line for uncomplicated hypertension because of weaker outcome data or side-effect burden.
A 58-year-old man with newly diagnosed hypertension also has stage 3 chronic kidney disease with albuminuria. When implementing antihypertensive therapy, which agent class is preferred to provide both blood pressure control and renal protection?
- A beta-blocker
- An ACE inhibitor or ARB
- A thiazide diuretic alone
- A dihydropyridine calcium channel blocker alone
Correct answer: An ACE inhibitor or ARB
An ACE inhibitor or ARB is preferred when hypertension coexists with chronic kidney disease and albuminuria. These agents reduce intraglomerular pressure and slow progression of albuminuric kidney disease, making them the compelling-indication choice. A calcium channel blocker or thiazide alone controls pressure but does not provide the same renoprotective albuminuria reduction.
When deciding between an ACE inhibitor and an ARB for a patient with hypertension, which clinical factor most appropriately favors choosing the ARB?
- The patient has developed a persistent dry cough on the ACE inhibitor
- The patient prefers a once-daily medication
- The patient has a serum potassium of 3.2 mEq/L
- The patient has no history of angioedema
Correct answer: The patient has developed a persistent dry cough on the ACE inhibitor
A persistent dry cough on an ACE inhibitor is the classic reason to switch to an ARB. ACE inhibitor cough results from bradykinin accumulation, which ARBs do not cause, so ARBs are preferred when cough or ACE-inhibitor-related angioedema occurs. Both classes are otherwise similarly effective and both can raise potassium, so hypokalemia and dosing frequency do not drive the choice.
A 47-year-old woman is newly diagnosed with type 2 diabetes (A1c 7.8%) and has an eGFR of 78 mL/min/1.73 m2 with no contraindications. In the absence of established cardiovascular or kidney disease, which first-line oral agent should the nurse practitioner initiate along with lifestyle changes?
- Metformin
- Glipizide
- Sitagliptin
- Pioglitazone
Correct answer: Metformin
Metformin is the first-line pharmacologic agent for most patients with type 2 diabetes, alongside lifestyle modification. It is favored for its glucose-lowering efficacy, weight neutrality, low hypoglycemia risk, and cost. Sulfonylureas, thiazolidinediones, and DPP-4 inhibitors are reserved for add-on or alternative use when metformin is contraindicated or insufficient.
Before initiating metformin in a patient with type 2 diabetes, which finding represents a contraindication that requires choosing an alternative agent?
- An eGFR of 24 mL/min/1.73 m2
- An A1c of 8.2%
- A body mass index of 31 kg/m2
- A fasting glucose of 168 mg/dL
Correct answer: An eGFR of 24 mL/min/1.73 m2
An eGFR of 24 mL/min/1.73 m2 contraindicates metformin. Metformin should not be started when eGFR is below 30 mL/min/1.73 m2 because of the increased risk of lactic acidosis, and continuation requires caution between 30 and 45. Obesity, an elevated A1c, and an elevated fasting glucose are reasons to treat, not contraindications.
A 62-year-old man with type 2 diabetes is being started on metformin. Which laboratory value should the nurse practitioner verify is acceptable before prescribing it?
- Serum amylase
- Total bilirubin
- Serum uric acid
- Renal function (eGFR or serum creatinine)
Correct answer: Renal function (eGFR or serum creatinine)
Renal function must be verified before starting metformin because it is cleared by the kidneys and accumulates in renal impairment, raising lactic acidosis risk. eGFR below 30 is a contraindication and the 30 to 45 range requires dose reduction. Amylase, uric acid, and bilirubin are not part of routine pre-metformin screening.
A 55-year-old woman is diagnosed with primary hypothyroidism (TSH 12 mIU/L) and has no cardiac disease. She weighs 70 kg. Using full weight-based replacement at about 1.6 mcg/kg/day, which initial daily levothyroxine dose is most appropriate?
- 112 mcg
- 300 mcg
- 25 mcg
- 50 mcg
Correct answer: 112 mcg
112 mcg daily is the appropriate full-replacement starting dose. At roughly 1.6 mcg/kg/day, a 70 kg patient needs about 112 mcg, and a commercially available 112 mcg tablet matches this. Doses of 25 to 50 mcg are reserved for older adults or those with cardiac disease, while 300 mcg far exceeds typical replacement needs.
A 74-year-old man with coronary artery disease is newly diagnosed with hypothyroidism. How should the nurse practitioner implement levothyroxine therapy in this patient?
- Withhold treatment until cardiac symptoms resolve
- Start full weight-based replacement immediately
- Start a low dose such as 25 to 50 mcg daily and titrate gradually
- Begin liothyronine instead of levothyroxine
Correct answer: Start a low dose such as 25 to 50 mcg daily and titrate gradually
Starting a low dose of about 25 to 50 mcg daily with gradual titration is correct for older adults and those with cardiac disease. A low, slow approach avoids precipitating angina, arrhythmia, or myocardial ischemia that abrupt full replacement could trigger. Full immediate replacement and routine liothyronine use are inappropriate here, and treatment should not be withheld.
After starting or adjusting levothyroxine for a patient with primary hypothyroidism, when should the nurse practitioner recheck the TSH to guide further dose titration?
- In 3 to 5 days
- In 1 week
- In 12 months
- In 6 to 8 weeks
Correct answer: In 6 to 8 weeks
TSH should be rechecked in about 6 to 8 weeks after starting or changing the dose. This interval allows the thyroid axis to reach a new steady state given levothyroxine's roughly 7-day half-life. Checking after only days or a week is too early to reflect equilibrium, and waiting a full year delays needed titration.
A patient is prescribed levothyroxine for hypothyroidism. Which administration instruction best ensures consistent absorption?
- Take it together with the morning calcium supplement
- Take it on an empty stomach with water, 30 to 60 minutes before breakfast
- Take it at bedtime immediately after a large meal
- Take it with a high-fiber breakfast
Correct answer: Take it on an empty stomach with water, 30 to 60 minutes before breakfast
Taking levothyroxine on an empty stomach with water 30 to 60 minutes before breakfast ensures consistent absorption. Food, fiber, and especially calcium or iron supplements bind the drug and reduce absorption, so separation in time is essential. Taking it with calcium or right after a large meal lowers and varies bioavailability.
A healthy 19-year-old presents with a sore throat, fever, tonsillar exudates, tender anterior cervical nodes, and no cough, and a rapid antigen test confirms group A streptococcal pharyngitis. She has no drug allergies. Which antibiotic is the recommended first-line treatment?
- Penicillin V or amoxicillin
- Azithromycin
- Ciprofloxacin
- Clindamycin
Correct answer: Penicillin V or amoxicillin
Penicillin V or amoxicillin is the first-line antibiotic for group A strep pharyngitis in a patient without penicillin allergy. These narrow-spectrum agents remain fully effective against group A strep, are inexpensive, and have low adverse-event rates. Macrolides, fluoroquinolones, and clindamycin are reserved for allergy or special circumstances and carry resistance concerns.
A patient with confirmed group A streptococcal pharyngitis reports a history of anaphylaxis to penicillin. Which oral antibiotic is an appropriate first-line alternative?
- Amoxicillin-clavulanate
- Azithromycin or clindamycin
- Cephalexin
- High-dose amoxicillin
Correct answer: Azithromycin or clindamycin
Azithromycin or clindamycin is appropriate for strep pharyngitis when the patient has anaphylaxis to penicillin. First-generation cephalosporins such as cephalexin should be avoided after an immediate-type penicillin reaction because of cross-reactivity, and amoxicillin-based regimens are contraindicated in penicillin allergy. Local macrolide resistance should be considered when azithromycin is chosen.
A 2-year-old child weighing 12 kg is diagnosed with acute otitis media and has no penicillin allergy or recent antibiotic use. Which first-line regimen and dose is most appropriate?
- Oral cephalexin 25 mg/kg/day
- High-dose amoxicillin 80 to 90 mg/kg/day in divided doses
- Standard-dose amoxicillin 20 mg/kg/day
- Azithromycin 5 mg/kg/day for 5 days
Correct answer: High-dose amoxicillin 80 to 90 mg/kg/day in divided doses
High-dose amoxicillin at 80 to 90 mg/kg/day in divided doses is first-line for uncomplicated acute otitis media in a child without recent antibiotics or penicillin allergy. The high dose overcomes intermediate penicillin resistance in Streptococcus pneumoniae. Macrolides and cephalexin are not preferred, and standard low-dose amoxicillin is inadequate against resistant pneumococcus.
A 3-year-old with acute otitis media received amoxicillin two weeks ago and now has purulent conjunctivitis along with the ear infection. Which antibiotic should the nurse practitioner select?
- Amoxicillin-clavulanate at high dose
- Nitrofurantoin
- Doxycycline
- Standard amoxicillin
Correct answer: Amoxicillin-clavulanate at high dose
High-dose amoxicillin-clavulanate is preferred here because recent amoxicillin use and concurrent purulent conjunctivitis suggest beta-lactamase-producing organisms such as Haemophilus influenzae and Moraxella catarrhalis. The clavulanate adds coverage these factors require. Plain amoxicillin would likely fail, and nitrofurantoin and doxycycline are not used for pediatric otitis media.
A previously healthy 45-year-old nonsmoker with no comorbidities is diagnosed with outpatient community-acquired pneumonia and can be managed at home. Which oral regimen is an appropriate first-line empiric choice?
- Nitrofurantoin
- Levofloxacin plus vancomycin
- Intravenous ceftriaxone
- High-dose amoxicillin or doxycycline
Correct answer: High-dose amoxicillin or doxycycline
High-dose amoxicillin or doxycycline is first-line for an otherwise healthy outpatient with community-acquired pneumonia. Current ATS/IDSA guidance recommends amoxicillin or doxycycline for low-risk patients without comorbidities. Combination broad-spectrum or intravenous regimens are reserved for patients with comorbidities, recent antibiotics, or severe disease, and nitrofurantoin treats urinary, not respiratory, infections.
An otherwise healthy nonpregnant 28-year-old woman has acute uncomplicated cystitis with dysuria and frequency and no fever or flank pain. Local resistance to trimethoprim-sulfamethoxazole exceeds 20 percent. Which first-line oral agent is most appropriate?
- Trimethoprim-sulfamethoxazole for 3 days
- Amoxicillin for 7 days
- Nitrofurantoin monohydrate/macrocrystals 100 mg twice daily for 5 days
- Ciprofloxacin for 7 days
Correct answer: Nitrofurantoin monohydrate/macrocrystals 100 mg twice daily for 5 days
Nitrofurantoin 100 mg twice daily for 5 days is an appropriate first-line agent for acute uncomplicated cystitis, especially where TMP-SMX resistance exceeds 20 percent. Nitrofurantoin has low resistance and minimal collateral damage. TMP-SMX is avoided when local resistance is high, fluoroquinolones are reserved due to toxicity, and amoxicillin has poor empiric efficacy.
A 30-year-old woman with acute uncomplicated cystitis has an eGFR of 25 mL/min/1.73 m2, which makes nitrofurantoin a poor choice. Which alternative single-dose first-line option is appropriate?
- A 14-day course of amoxicillin
- Ciprofloxacin for 10 days
- Doxycycline for 7 days
- Fosfomycin 3 g as a single dose
Correct answer: Fosfomycin 3 g as a single dose
Fosfomycin 3 g as a single dose is an appropriate first-line alternative for uncomplicated cystitis when reduced renal function makes nitrofurantoin unsuitable. Nitrofurantoin loses efficacy and accumulates with low eGFR, while fosfomycin provides convenient single-dose therapy. Prolonged amoxicillin, fluoroquinolone, or doxycycline courses are not preferred empiric choices.
A 24-year-old man presents with an acute productive cough for 6 days, low-grade symptoms, normal vital signs, and a clear chest exam without signs of pneumonia. He is diagnosed with acute bronchitis. What is the most appropriate management?
- Supportive care and symptom relief without routine antibiotics
- Oral prednisone taper
- Empiric azithromycin
- High-dose amoxicillin
Correct answer: Supportive care and symptom relief without routine antibiotics
Supportive care without routine antibiotics is correct for acute bronchitis, which is almost always viral. Education on expected cough duration, fluids, rest, and symptom relief is the standard, and antibiotics do not shorten illness while promoting resistance. Routine antibiotics and systemic steroids are not indicated when pneumonia and asthma are absent.
A patient with newly diagnosed mild persistent asthma asks what controller therapy will best reduce long-term inflammation and exacerbations. According to current guidance, which is the preferred first-line controller approach?
- An oral leukotriene receptor antagonist alone
- An inhaled corticosteroid (often combined with formoterol as needed)
- A short-acting beta-agonist used alone as needed
- Daily oral corticosteroids
Correct answer: An inhaled corticosteroid (often combined with formoterol as needed)
An inhaled corticosteroid, frequently paired with as-needed formoterol, is the preferred first-line controller for persistent asthma. ICS-containing therapy addresses underlying airway inflammation and reduces exacerbations and mortality. Reliever-only SABA therapy is no longer recommended as a stand-alone strategy, and chronic oral steroids are reserved for severe refractory disease.
A patient with COPD has persistent dyspnea and a low exacerbation risk despite intermittent short-acting bronchodilator use. According to GOLD guidance, which is the preferred first-line maintenance therapy?
- Long-term daily oral prednisone
- A long-acting bronchodilator (LABA and/or LAMA)
- A daily inhaled corticosteroid alone
- Chronic oral azithromycin
Correct answer: A long-acting bronchodilator (LABA and/or LAMA)
A long-acting bronchodilator (LABA, LAMA, or both) is the preferred first-line maintenance therapy for symptomatic COPD with low exacerbation risk. Long-acting bronchodilators improve symptoms and lung function and are the foundation of maintenance therapy. Inhaled steroids are added based on exacerbations and eosinophils, and chronic systemic steroids or routine antibiotics are not first-line maintenance.
A 52-year-old man has a 10-year ASCVD risk of 12 percent, LDL of 150 mg/dL, and no diabetes or established cardiovascular disease. According to ACC/AHA guidance, what is the recommended first-line pharmacologic therapy for his hyperlipidemia?
- Niacin
- A fibrate such as gemfibrozil
- Ezetimibe monotherapy
- A moderate- to high-intensity statin
Correct answer: A moderate- to high-intensity statin
A moderate- to high-intensity statin is first-line for hyperlipidemia in a patient with intermediate ASCVD risk. Statins have the strongest outcome evidence for reducing cardiovascular events. Ezetimibe is an add-on when statins are insufficient or not tolerated, and fibrates and niacin are not first-line for LDL-driven risk reduction.
A 44-year-old man with type 2 diabetes and an LDL of 110 mg/dL has no symptoms of cardiovascular disease. Based on current guidance, when should statin therapy be started in patients with diabetes?
- Statins are contraindicated in diabetes
- Only after a documented myocardial infarction
- Only if the LDL exceeds 190 mg/dL
- Most adults aged 40 to 75 with diabetes should receive at least moderate-intensity statin therapy
Correct answer: Most adults aged 40 to 75 with diabetes should receive at least moderate-intensity statin therapy
Most adults aged 40 to 75 with diabetes should receive at least a moderate-intensity statin regardless of baseline LDL. Diabetes is a major risk enhancer, so statin therapy is recommended in this age range without waiting for an event. Reserving statins only for those with prior infarction or very high LDL would undertreat this group, and statins are not contraindicated in diabetes.
During a wellness visit, a 40-year-old patient asks at what point statin therapy should be considered for primary prevention. Which scenario most clearly warrants initiating a statin?
- A total cholesterol of 180 mg/dL
- An LDL cholesterol of 95 mg/dL with no risk factors
- An HDL of 60 mg/dL alone
- An LDL cholesterol of 190 mg/dL or higher
Correct answer: An LDL cholesterol of 190 mg/dL or higher
An LDL cholesterol of 190 mg/dL or higher clearly warrants statin therapy. Severe LDL elevation, often reflecting familial hypercholesterolemia, is one of the four statin benefit groups and merits high-intensity treatment regardless of calculated risk. A normal LDL with no risk factors, a normal total cholesterol, or a protective HDL alone does not trigger statin initiation.
A 30-year-old presents with facial pain, purulent nasal discharge, and congestion that began 3 days ago and is improving. The clinical picture is consistent with acute viral rhinosinusitis. When is it appropriate to prescribe an antibiotic?
- Never, regardless of duration
- Only if the patient requests one
- Immediately for any sinus symptoms
- When symptoms persist beyond 10 days without improvement, are severe at onset, or worsen after initial improvement
Correct answer: When symptoms persist beyond 10 days without improvement, are severe at onset, or worsen after initial improvement
Antibiotics for sinusitis are appropriate when symptoms persist beyond 10 days without improvement, are severe at onset (high fever plus purulent discharge for several days), or worsen after initial improvement (double-worsening). Most acute rhinosinusitis is viral and self-limited, so early or automatic antibiotics are inappropriate, but bacterial sinusitis identified by these criteria does warrant treatment.
A 6-year-old presents with rapidly spreading warmth, redness, swelling, and tenderness of the lower leg without abscess or systemic toxicity, consistent with nonpurulent cellulitis. When implementing outpatient treatment, which empiric oral antibiotic class is appropriate?
- A beta-lactam active against streptococci, such as cephalexin
- Fluconazole
- Nitrofurantoin
- Metronidazole alone
Correct answer: A beta-lactam active against streptococci, such as cephalexin
A beta-lactam such as cephalexin is appropriate empiric therapy for nonpurulent cellulitis, which is most often caused by beta-hemolytic streptococci. Coverage targeting streptococci is the priority when there is no purulence or abscess. Nitrofurantoin treats urinary infection, metronidazole covers anaerobes, and fluconazole is an antifungal, none of which target this organism.
A nurse practitioner is treating a patient with cellulitis of the forearm. Which intervention best supports resolution alongside antibiotics?
- Incising the area at the first sign of redness
- Applying ice packs continuously to the area
- Elevating the affected limb and marking the borders of erythema to monitor progression
- Restricting all fluid intake
Correct answer: Elevating the affected limb and marking the borders of erythema to monitor progression
Elevating the limb and marking the erythema borders best supports cellulitis management. Elevation reduces edema and promotes drainage, and outlining the redness lets the clinician objectively track response or progression. Continuous ice, premature incision of nonpurulent cellulitis, and fluid restriction are not appropriate interventions.
A parent asks the nurse practitioner why the childhood immunization schedule spaces certain vaccines and at what age key shots are due. Which statement accurately reflects the routine childhood immunization schedule?
- Hepatitis B is first given at 5 years of age
- DTaP is a single one-time dose
- The first dose of MMR is given at birth
- The first dose of MMR is recommended at 12 to 15 months of age
Correct answer: The first dose of MMR is recommended at 12 to 15 months of age
The first MMR dose is recommended at 12 to 15 months. Live MMR is delayed until this age because maternal antibodies can interfere with the response earlier, and a second dose follows at 4 to 6 years. DTaP requires a multi-dose primary series, and the first hepatitis B dose is given at birth, not at age 5.
A 12-year-old presents for routine care and has never received HPV vaccine. At what age does the routine HPV vaccination series begin, and when can it be started early?
- Routinely recommended at 11 to 12 years and may be started as early as age 9
- Routinely started at age 5
- Only recommended after age 18
- Given only to females
Correct answer: Routinely recommended at 11 to 12 years and may be started as early as age 9
HPV vaccination is routinely recommended at 11 to 12 years and may begin as early as age 9. Starting before sexual exposure maximizes protection, and vaccination is recommended for all adolescents regardless of sex. It is not restricted to those over 18 or to females, and it is not given to young children at age 5.
A 9-year-old presents whose parents wish to begin HPV vaccination early after a clinician recommendation. For a child who starts the HPV series before the 15th birthday, how many doses are required?
- A single one-time dose only
- Two doses given 6 to 12 months apart
- Five doses in the first year
- Four doses over 2 years
Correct answer: Two doses given 6 to 12 months apart
A child who starts the HPV series before age 15 needs two doses given 6 to 12 months apart. The two-dose schedule applies to immunocompetent adolescents starting young, whereas those who begin at 15 or older or who are immunocompromised require three doses. Single-dose, four-dose, and five-dose schedules are not the standard immunocompetent regimens.
A nurse practitioner is administering an intramuscular vaccine to a healthy 9-month-old infant. Which site is the preferred location for intramuscular injection at this age?
- The ventrogluteal region only
- The vastus lateralis (anterolateral thigh)
- The dorsogluteal region
- The deltoid muscle
Correct answer: The vastus lateralis (anterolateral thigh)
The vastus lateralis of the anterolateral thigh is the preferred intramuscular site for infants. It has adequate muscle mass and avoids major nerves and vessels. The deltoid is too small until toddlers and older children, and the dorsogluteal site is avoided in young children because of sciatic nerve injury risk.
A 26-year-old woman seeks contraception counseling and wants the most effective reversible method. When implementing patient-centered counseling, which statement is accurate about long-acting reversible contraception (LARC)?
- LARC methods are less effective than condoms
- Intrauterine devices and the contraceptive implant are the most effective reversible methods and are appropriate first-tier options
- LARC requires daily user action to remain effective
- LARC permanently sterilizes the patient
Correct answer: Intrauterine devices and the contraceptive implant are the most effective reversible methods and are appropriate first-tier options
Intrauterine devices and the contraceptive implant are the most effective reversible methods and are appropriate first-tier options to offer. Because they do not depend on daily adherence, their typical-use failure rates are very low. They are far more effective than condoms, require no daily action, and are fully reversible rather than sterilizing.
During contraception counseling, a 32-year-old woman who smokes more than 15 cigarettes daily and is over 35 asks about combined oral contraceptives. How should the nurse practitioner respond?
- She cannot use any form of contraception
- Combined estrogen-containing contraceptives are generally contraindicated, so offer a progestin-only or nonhormonal method
- Only emergency contraception is appropriate for her
- Combined pills are the safest choice for her
Correct answer: Combined estrogen-containing contraceptives are generally contraindicated, so offer a progestin-only or nonhormonal method
For a woman over 35 who smokes 15 or more cigarettes daily, combined estrogen-containing contraceptives are generally contraindicated due to elevated thromboembolic and cardiovascular risk, so progestin-only or nonhormonal options should be offered. This reflects standard medical eligibility criteria. She can safely use several methods, so it is incorrect to say no contraception or only emergency contraception is appropriate.
A 50-year-old patient who smokes one pack daily expresses willingness to quit. When implementing evidence-based smoking cessation counseling, which approach is most effective?
- Recommend abrupt cessation without any support
- Combine behavioral counseling with pharmacotherapy such as varenicline or nicotine replacement
- Advise willpower alone without medication
- Suggest only switching to low-tar cigarettes
Correct answer: Combine behavioral counseling with pharmacotherapy such as varenicline or nicotine replacement
Combining behavioral counseling with pharmacotherapy such as varenicline or nicotine replacement is the most effective cessation strategy. The combination roughly doubles quit rates compared with either alone. Willpower without support, unstructured abrupt quitting, and switching cigarette types are far less effective and not recommended.
When counseling a patient on smoking cessation using a brief structured framework, which set of steps reflects the recommended approach used in primary care?
- Restrict, Reprimand, and Refer
- Observe and wait until the patient quits independently
- Ask, Advise, Assess, Assist, and Arrange follow-up
- Diagnose, Discharge, and Document only
Correct answer: Ask, Advise, Assess, Assist, and Arrange follow-up
The Ask, Advise, Assess, Assist, Arrange (the 5 A's) framework is the recommended brief intervention for smoking cessation. It systematically identifies smokers, advises quitting, gauges readiness, provides support and pharmacotherapy, and ensures follow-up. Reprimanding, passive waiting, or documentation alone are not evidence-based counseling strategies.
A nurse practitioner is teaching a newly diagnosed patient with type 2 diabetes how to use a glucometer at home. Which teaching technique best confirms the patient can perform the skill correctly?
- Use teach-back by having the patient demonstrate the procedure and restate the steps
- Provide a written pamphlet and end the visit
- Assume understanding if the patient nods
- Tell the patient to watch online videos later
Correct answer: Use teach-back by having the patient demonstrate the procedure and restate the steps
Teach-back, in which the patient demonstrates the procedure and restates the steps, best confirms skill mastery. It verifies understanding rather than assuming it and allows correction of errors in real time. Handing over a pamphlet, deferring to videos, or relying on nodding does not confirm comprehension.
When providing patient education to an adult with limited health literacy, which strategy most improves understanding and retention?
- Provide only highly technical written handouts
- Deliver all instructions verbally in a single long session
- Use detailed medical terminology to be precise
- Use plain language, limit to a few key points, and confirm with teach-back
Correct answer: Use plain language, limit to a few key points, and confirm with teach-back
Using plain language, limiting to a few key points, and confirming with teach-back most improves understanding for patients with limited health literacy. Simplifying vocabulary, chunking information, and verifying comprehension are core health-literacy strategies. Heavy jargon, information overload, and technical-only handouts impair rather than aid learning.
Before performing an in-office incision and drainage of an abscess, the nurse practitioner reviews the procedure, risks, benefits, and alternatives with the patient and answers questions. This process of obtaining informed consent in primary care primarily ensures which element is met?
- The patient has the capacity to make a voluntary, informed decision and agrees to proceed
- The procedure is billed at the highest code
- Consent can be assumed because the patient came to the visit
- The clinician is protected from all liability
Correct answer: The patient has the capacity to make a voluntary, informed decision and agrees to proceed
Informed consent ensures the patient has decision-making capacity and makes a voluntary, informed choice to proceed. Disclosing the nature, risks, benefits, and alternatives and confirming understanding fulfills this ethical and legal requirement to implement a procedure. Consent is not about billing, does not eliminate all liability, and cannot be merely assumed from attendance.
A nurse practitioner plans a minor office procedure for an alert adult patient. Which situation would allow proceeding without formal informed consent?
- The procedure is routine and commonly performed
- A true emergency in which the patient is unable to consent and delay would cause serious harm
- The clinician believes the patient will agree anyway
- The patient seems hurried and impatient
Correct answer: A true emergency in which the patient is unable to consent and delay would cause serious harm
A true emergency in which the patient cannot consent and delay would cause serious harm permits proceeding under implied (emergency) consent. The presumption is that a reasonable person would consent to life- or limb-saving care. A patient being hurried, a clinician's assumption of agreement, or a procedure's routine nature do not waive the consent requirement.
A patient asks whether a nurse practitioner is allowed to prescribe medications and manage chronic conditions independently. Which statement best describes the scope of practice for nurse practitioners?
- Nurse practitioners can never prescribe any medication
- Scope of practice, including prescriptive authority, is defined by state law and the NP's certification and varies by state
- Nurse practitioners may practice only under direct physician supervision everywhere
- Scope of practice is identical in every state
Correct answer: Scope of practice, including prescriptive authority, is defined by state law and the NP's certification and varies by state
Nurse practitioner scope of practice, including prescriptive authority, is defined by state law and certification and varies by state. Some states grant full practice authority while others require collaboration or supervision. It is incorrect that NPs can never prescribe, that scope is uniform nationwide, or that physician supervision is universally required.
A nurse practitioner identifies a patient problem that falls clearly outside the NP's training, certification, and legal scope of practice. What is the most appropriate action when implementing care?
- Document that nothing can be done
- Refer or consult with the appropriate specialist or provider
- Proceed anyway since the patient is already present
- Decline to address the issue and offer no alternative
Correct answer: Refer or consult with the appropriate specialist or provider
Referring or consulting the appropriate specialist is correct when a problem falls outside the NP's scope of practice. Recognizing limits and arranging the right level of care protects patient safety and meets professional and legal standards. Proceeding beyond competence, abandoning the patient without options, or dismissively documenting inaction are all inappropriate.
A nurse practitioner is implementing first-line therapy for a 60-year-old man with stage 1 hypertension who is Black and has no chronic kidney disease or heart failure. Which initial single-agent choice is supported by current evidence for this patient?
- A thiazide-type diuretic or a dihydropyridine calcium channel blocker
- An ACE inhibitor as the sole preferred agent
- A beta-blocker as first-line monotherapy
- An alpha-blocker as first-line monotherapy
Correct answer: A thiazide-type diuretic or a dihydropyridine calcium channel blocker
For Black adults without chronic kidney disease or heart failure, initial therapy with a thiazide-type diuretic or a dihydropyridine calcium channel blocker is supported by evidence showing greater blood-pressure response than ACE inhibitor monotherapy in this group. ACE inhibitors remain appropriate when there is a compelling indication, but beta-blockers and alpha-blockers are not first-line for uncomplicated hypertension.
A nurse practitioner is teaching a child's caregiver how to correctly administer a metered-dose inhaler with a spacer for asthma controller therapy. Which instruction is most important for effective drug delivery?
- Have the child exhale forcefully into the spacer right after each puff
- Shake the inhaler, attach the spacer, and have the child take slow deep breaths after actuation
- Actuate two puffs simultaneously into the spacer before inhaling
- Discard the spacer and inhale directly for better delivery
Correct answer: Shake the inhaler, attach the spacer, and have the child take slow deep breaths after actuation
Shaking the inhaler, attaching the spacer, and having the child take slow deep breaths after a single actuation gives the best drug delivery. The spacer reduces the need for precise coordination and improves lung deposition in children. Firing multiple puffs at once, exhaling into the spacer after actuation, or skipping the spacer all reduce delivered dose.
A nurse practitioner is initiating an inhaled corticosteroid for a patient with persistent asthma. Which patient education point helps prevent a common local adverse effect?
- Take the inhaler only when symptomatic
- Double the dose if a dose is missed
- Hold the breath for less than one second after inhaling
- Rinse the mouth with water and spit after each use to prevent oral candidiasis
Correct answer: Rinse the mouth with water and spit after each use to prevent oral candidiasis
Rinsing the mouth with water and spitting after each inhaled corticosteroid dose prevents oral candidiasis (thrush), a common local side effect from residual steroid in the oropharynx. Controller ICS must be used regularly rather than only when symptomatic, doses should not be doubled after a miss, and a brief breath-hold improves deposition.
A patient with chronic kidney disease and uncomplicated stage 2 hypertension is started on an ACE inhibitor. Which monitoring step should the nurse practitioner implement shortly after initiation?
- Order liver function tests every 3 days
- Check serum calcium daily
- Recheck serum creatinine and potassium within 1 to 2 weeks
- Recheck a complete blood count weekly
Correct answer: Recheck serum creatinine and potassium within 1 to 2 weeks
Rechecking serum creatinine and potassium within 1 to 2 weeks after starting an ACE inhibitor is the correct monitoring step. ACE inhibitors can raise potassium and transiently increase creatinine, particularly in chronic kidney disease, so early labs detect significant changes. Routine weekly CBCs, frequent liver tests, and daily calcium checks are not indicated for ACE inhibitor initiation.
A nurse practitioner is implementing a thiazide diuretic for a 65-year-old woman with uncomplicated primary hypertension. Which monitoring and education step is most important during the first weeks of therapy?
- Monitor for hypokalemia and hyponatremia and counsel on signs of dehydration
- Advise the patient to take it at bedtime to reduce daytime urination
- Check creatinine kinase weekly for myopathy
- Restrict all dietary sodium to zero
Correct answer: Monitor for hypokalemia and hyponatremia and counsel on signs of dehydration
Monitoring for hypokalemia and hyponatremia and counseling on dehydration signs is most important when implementing thiazide therapy. Thiazides commonly cause electrolyte loss, so checking potassium and sodium and educating the patient detects problems early. A zero-sodium diet is not advised, creatine kinase monitoring is for statin myopathy, and thiazides are taken in the morning to avoid nocturia.
A 4-month-old infant who was not protected by maternal RSV vaccination during pregnancy presents in late October for a well-child visit. According to the 2026 immunization schedule, which preventive product should the nurse practitioner offer to reduce severe RSV disease?
- The live attenuated intranasal RSV vaccine
- A single dose of nirsevimab (or clesrovimab) monoclonal antibody
- A two-dose primary series of inactivated RSV vaccine
- No RSV prophylaxis until the infant reaches 12 months
Correct answer: A single dose of nirsevimab (or clesrovimab) monoclonal antibody
A single dose of nirsevimab or clesrovimab monoclonal antibody is recommended for infants younger than 8 months entering or born during their first RSV season when the mother was not effectively vaccinated with the maternal RSV vaccine during pregnancy. These long-acting monoclonal antibodies provide passive immunization; there is no live intranasal or multi-dose inactivated RSV vaccine routinely given to young infants, so those choices are incorrect.
A nurse practitioner is reviewing the catch-up schedule for an unvaccinated 7-year-old. Which vaccine should the NP recognize is no longer indicated once a child has passed the upper age limit for its routine series?
- Rotavirus vaccine
- Inactivated poliovirus vaccine
- Hepatitis B vaccine
- Measles-mumps-rubella vaccine
Correct answer: Rotavirus vaccine
Rotavirus vaccine is not given to a 7-year-old because the maximum age to start the series is 14 weeks 6 days and the final dose must be by 8 months 0 days; once a child exceeds these limits, rotavirus is never administered. Inactivated poliovirus, MMR, and hepatitis B can all be caught up at age 7, so they remain indicated.
A 15-year-old who received a single dose of HPV vaccine at age 13 returns for care. The nurse practitioner notes the first dose was given before the 15th birthday. How many additional HPV doses are needed to complete the routine series?
- No additional doses; one dose is sufficient
- Three additional doses for a four-dose series total
- One additional dose for a two-dose series total
- Two additional doses for a three-dose series total
Correct answer: One additional dose for a two-dose series total
One additional dose completes the series because a person who begins HPV vaccination before the 15th birthday needs only two total doses spaced at least 6 to 12 months apart. A three-dose schedule applies only when the series is started at age 15 or older or when there is immunocompromise, so two additional doses would be incorrect here.
A 28-year-old woman with primary hypothyroidism becomes pregnant and reports she takes levothyroxine 100 mcg daily. What is the most appropriate immediate action regarding her levothyroxine dose?
- Continue the same dose with no change throughout pregnancy
- Switch her to liothyronine for better fetal absorption
- Stop levothyroxine until the second trimester
- Increase the levothyroxine dose by approximately 20 to 30 percent and recheck TSH promptly
Correct answer: Increase the levothyroxine dose by approximately 20 to 30 percent and recheck TSH promptly
Increasing the levothyroxine dose by roughly 20 to 30 percent as soon as pregnancy is confirmed is correct because thyroid hormone requirements rise early in gestation to support fetal neurodevelopment, and TSH should be rechecked within about 4 weeks. Stopping the drug or keeping the dose unchanged risks maternal hypothyroidism, and liothyronine is not used in pregnancy.
A nurse practitioner is implementing therapy for a 62-year-old with type 2 diabetes who also has heart failure with reduced ejection fraction. Which medication class should be prioritized to provide cardiovascular and kidney benefit?
- A dipeptidyl peptidase-4 (DPP-4) inhibitor
- A sulfonylurea
- A thiazolidinedione
- An SGLT2 inhibitor
Correct answer: An SGLT2 inhibitor
An SGLT2 inhibitor with demonstrated benefit is prioritized for type 2 diabetes with heart failure because current standards recommend it independent of A1c and background metformin to reduce heart failure hospitalization and slow kidney disease. Sulfonylureas and DPP-4 inhibitors lack this cardioprotective evidence, and thiazolidinediones can worsen fluid retention and heart failure.
A nurse practitioner starts a high-dose statin for a 60-year-old with established coronary artery disease. Which baseline laboratory test is most appropriate to obtain before initiating therapy?
- A coagulation panel with INR
- A fasting or non-fasting lipid panel and a baseline ALT
- A serum creatine kinase on every patient regardless of symptoms
- A thyroid-stimulating hormone weekly for the first month
Correct answer: A fasting or non-fasting lipid panel and a baseline ALT
A lipid panel and a baseline ALT (hepatic transaminase) are appropriate before starting a statin to document the starting LDL for monitoring response and to establish liver function. Routine creatine kinase is checked only if the patient has muscle symptoms or risk factors, weekly TSH is unnecessary, and coagulation testing is not part of statin initiation.
A 6-month-old is due for routine vaccines. The nurse practitioner plans an intramuscular injection. Which site is preferred for an infant of this age?
- The vastus lateralis (anterolateral thigh)
- The ventrogluteal hip region
- The dorsogluteal (upper outer buttock)
- The deltoid muscle of the upper arm
Correct answer: The vastus lateralis (anterolateral thigh)
The vastus lateralis of the anterolateral thigh is the preferred intramuscular site for infants under 12 months because it has the largest muscle mass at that age. The deltoid is too small until toddlerhood, and gluteal sites are avoided in infants because of the risk of sciatic nerve injury and reduced immune response.
A 35-year-old man is diagnosed with acute uncomplicated sinusitis and has had purulent discharge and facial pain for 8 days that has not improved. Which first-line antibiotic should the nurse practitioner implement if he has no penicillin allergy?
- Amoxicillin-clavulanate
- Trimethoprim-sulfamethoxazole
- Levofloxacin
- Azithromycin
Correct answer: Amoxicillin-clavulanate
Amoxicillin-clavulanate is the recommended first-line antibiotic for acute bacterial sinusitis when treatment is warranted after symptoms persist 10 days or worsen, because it covers common pathogens including beta-lactamase producing strains. Macrolides and trimethoprim-sulfamethoxazole have high pneumococcal resistance, and respiratory fluoroquinolones are reserved for penicillin allergy or treatment failure.
A nurse practitioner manages a 50-year-old with uncomplicated stage 1 hypertension and a 10-year ASCVD risk above 10 percent. Which thiazide-type agent is generally preferred for its longer duration and stronger outcome evidence?
- Furosemide
- Chlorthalidone
- Spironolactone
- Hydrochlorothiazide 12.5 mg
Correct answer: Chlorthalidone
Chlorthalidone is often preferred among thiazide-type diuretics because it has a longer half-life and stronger cardiovascular outcome data than hydrochlorothiazide. Furosemide is a loop diuretic not used for routine hypertension, and spironolactone is a potassium-sparing agent reserved for resistant hypertension rather than first-line monotherapy.
A nurse practitioner prescribes nitrofurantoin for a 30-year-old woman with acute uncomplicated cystitis. Which counseling point about administration is most important to ensure efficacy?
- Take each dose with food to improve absorption and reduce stomach upset
- Take it on an empty stomach at least 1 hour before meals
- Restrict all fluids while taking the medication
- Crush the capsule and dissolve it in juice
Correct answer: Take each dose with food to improve absorption and reduce stomach upset
Taking nitrofurantoin with food is correct because food enhances absorption and decreases gastrointestinal irritation. Fluid restriction is wrong since adequate hydration supports recovery, and the capsule should be swallowed whole; nitrofurantoin is not the agent to take on an empty stomach.
A nurse practitioner is implementing treatment for a 5-year-old, 20 kg child with severe acute otitis media and no penicillin allergy or recent antibiotic use. What is the most appropriate amoxicillin regimen?
- Azithromycin 10 mg/kg as a single dose
- Standard-dose amoxicillin 40 mg/kg/day for 3 days
- Amoxicillin 90 mg/kg/day for 5 days
- High-dose amoxicillin 80 to 90 mg/kg/day divided twice daily for 10 days
Correct answer: High-dose amoxicillin 80 to 90 mg/kg/day divided twice daily for 10 days
High-dose amoxicillin at 80 to 90 mg/kg/day divided twice daily is first-line for acute otitis media, and a 10-day course is recommended for children with severe symptoms. A 5-day course is reserved for older children with mild disease, standard low-dose therapy is inadequate against resistant pneumococcus, and azithromycin is not first-line because of resistance.
A 22-year-old woman with confirmed group A streptococcal pharyngitis and a documented penicillin allergy without anaphylaxis is being treated. Which oral antibiotic is an appropriate first-line alternative?
- Metronidazole
- Ciprofloxacin
- A first-generation cephalosporin such as cephalexin
- Doxycycline
Correct answer: A first-generation cephalosporin such as cephalexin
A narrow-spectrum first-generation cephalosporin like cephalexin is an appropriate alternative for strep throat in patients with non-anaphylactic penicillin allergy because cross-reactivity is low. Doxycycline and metronidazole do not reliably cover group A streptococcus, and fluoroquinolones are not indicated for routine pharyngitis.
A nurse practitioner provides discharge education to a patient newly started on warfarin. Which symptom should the NP instruct the patient to report immediately as a sign of bleeding complication?
- Increased daytime sleepiness
- A metallic taste in the mouth
- Mild transient nausea after the first dose
- Black, tarry stools or blood in the urine
Correct answer: Black, tarry stools or blood in the urine
Black tarry stools or blood in the urine signal gastrointestinal or urinary bleeding and must be reported immediately when a patient is on warfarin. Mild nausea, taste changes, and sleepiness are not specific warning signs of the major hemorrhagic complications that warfarin can cause.
A nurse practitioner is implementing first-line pharmacologic therapy for a 38-year-old with newly diagnosed mild persistent asthma. According to current stepwise guidance, which regimen is preferred?
- A long-acting beta-agonist used alone daily
- An oral leukotriene receptor antagonist as monotherapy first-line
- A low-dose inhaled corticosteroid-formoterol used as both controller and reliever
- A short-acting beta-agonist alone used as needed
Correct answer: A low-dose inhaled corticosteroid-formoterol used as both controller and reliever
Low-dose inhaled corticosteroid combined with formoterol used as both maintenance and reliever therapy is the preferred approach because it reduces exacerbations more than reliever monotherapy. A short-acting beta-agonist alone does not treat underlying inflammation, a long-acting beta-agonist alone is unsafe in asthma, and leukotriene antagonists are not preferred first-line.
A nurse practitioner counsels a 45-year-old patient ready to quit smoking and discusses pharmacotherapy. Which first-line medication has the highest single-agent efficacy for smoking cessation?
- Bupropion combined with a benzodiazepine
- Varenicline
- Clonidine
- A short course of an inhaled corticosteroid
Correct answer: Varenicline
Varenicline is the most effective single first-line pharmacotherapy for smoking cessation because it partially agonizes nicotinic receptors to reduce craving and withdrawal. Clonidine is only second-line, inhaled corticosteroids have no role in cessation, and benzodiazepines are not part of standard cessation regimens.
A 70-year-old with GOLD group E COPD has frequent exacerbations despite dual long-acting bronchodilator therapy and an elevated blood eosinophil count. Which addition to the regimen is most appropriate?
- An antitussive at bedtime
- An inhaled corticosteroid to form triple therapy
- A long-term oral corticosteroid taper
- Daily prophylactic short-acting beta-agonist scheduled around the clock
Correct answer: An inhaled corticosteroid to form triple therapy
Adding an inhaled corticosteroid to dual bronchodilator therapy (triple therapy) is appropriate for COPD patients with frequent exacerbations and elevated blood eosinophils. Chronic oral steroids cause systemic toxicity and are avoided, scheduled short-acting beta-agonists do not prevent exacerbations, and antitussives do not modify disease.
A nurse practitioner manages a 58-year-old with newly diagnosed primary hypertension and comorbid type 2 diabetes with albuminuria. Which antihypertensive class should be implemented preferentially?
- A nondihydropyridine calcium channel blocker
- A beta-blocker
- An ACE inhibitor or ARB
- An alpha-blocker
Correct answer: An ACE inhibitor or ARB
An ACE inhibitor or ARB is preferred for hypertension when albuminuria is present because these agents reduce intraglomerular pressure and slow progression of diabetic kidney disease. Beta-blockers and alpha-blockers are not first-line for uncomplicated hypertension, and calcium channel blockers lack the same renal-protective albuminuria benefit.
During contraception counseling, a 35-year-old healthy nonsmoker asks for a method that also reduces menstrual bleeding and dysmenorrhea. Which option best meets both goals?
- Male condoms used consistently
- A copper intrauterine device
- Fertility awareness-based methods
- A levonorgestrel-releasing intrauterine system
Correct answer: A levonorgestrel-releasing intrauterine system
The levonorgestrel-releasing intrauterine system is highly effective contraception that also reduces menstrual blood loss and dysmenorrhea through local progestin effects on the endometrium. The copper IUD often increases bleeding and cramping, and condoms and fertility awareness do not improve bleeding patterns.
A nurse practitioner is starting therapy for a 65-year-old with COPD who has persistent breathlessness and a low exacerbation history. Which maintenance regimen is most appropriate to begin?
- A long-acting bronchodilator (LAMA or LABA)
- An as-needed short-acting beta-agonist with no maintenance therapy
- Daily oral theophylline
- An inhaled corticosteroid as monotherapy
Correct answer: A long-acting bronchodilator (LAMA or LABA)
A single long-acting bronchodilator (a long-acting muscarinic antagonist or long-acting beta-agonist) is the appropriate initial maintenance therapy for symptomatic COPD with low exacerbation risk. Inhaled corticosteroid monotherapy is not recommended in COPD, theophylline has a narrow therapeutic window, and relying on a reliever alone undertreats persistent symptoms.
A nurse practitioner provides medication teaching to a parent administering high-dose amoxicillin suspension to a toddler. Which instruction best ensures a complete and effective course?
- Double the next dose if one is missed by several hours
- Give every dose for the full prescribed duration even if the child seems better
- Save remaining medication for the next ear infection
- Stop the antibiotic as soon as the fever resolves
Correct answer: Give every dose for the full prescribed duration even if the child seems better
Completing the full prescribed course even after symptoms improve is essential to eradicate the pathogen and prevent recurrence or resistance. Stopping early, saving leftovers, and doubling doses all promote treatment failure, resistance, or toxicity and are incorrect counseling.
A 48-year-old man is diagnosed with outpatient community-acquired pneumonia and has comorbid diabetes and COPD but no recent antibiotics. Which oral regimen is appropriate first-line implementation?
- Nitrofurantoin
- Trimethoprim-sulfamethoxazole alone
- Amoxicillin monotherapy
- Amoxicillin-clavulanate plus a macrolide, or a respiratory fluoroquinolone
Correct answer: Amoxicillin-clavulanate plus a macrolide, or a respiratory fluoroquinolone
For outpatient pneumonia with comorbidities, beta-lactam (such as amoxicillin-clavulanate) plus a macrolide or a respiratory fluoroquinolone monotherapy is recommended to cover resistant pneumococcus and atypical organisms. Amoxicillin monotherapy is reserved for healthy patients without comorbidities, and the other agents do not adequately treat pneumonia.
A 19-year-old presents with an acute cough productive of clear sputum for 7 days, no fever, normal vital signs, and a clear chest exam. Which intervention is most appropriate for this likely acute bronchitis?
- An oral corticosteroid burst
- Azithromycin for 5 days
- Amoxicillin-clavulanate for 10 days
- Supportive care and symptom education without antibiotics
Correct answer: Supportive care and symptom education without antibiotics
Supportive care without antibiotics is correct because acute bronchitis in an otherwise healthy adult is almost always viral and self-limited, so antibiotics offer no benefit and add harm. Routine antibiotics and systemic corticosteroids are not indicated for uncomplicated acute bronchitis.
A nurse practitioner is initiating levothyroxine for an otherwise healthy 40-year-old with overt hypothyroidism. Which administration instruction supports consistent absorption?
- Take it on an empty stomach with water 30 to 60 minutes before breakfast
- Take it with coffee each morning
- Take it with a calcium supplement to improve absorption
- Take it at bedtime immediately after a high-fat snack
Correct answer: Take it on an empty stomach with water 30 to 60 minutes before breakfast
Taking levothyroxine on an empty stomach with water 30 to 60 minutes before breakfast maximizes and standardizes absorption. Calcium, iron, and food including coffee all bind levothyroxine and reduce absorption, so co-administration with these is incorrect.
A nurse practitioner manages a previously healthy 6-year-old with nonpurulent cellulitis of the lower leg, no abscess, and no systemic toxicity. Which empiric oral antibiotic targets the most likely pathogen?
- Cephalexin (targeting beta-hemolytic streptococci)
- Metronidazole
- Trimethoprim-sulfamethoxazole alone
- Nitrofurantoin
Correct answer: Cephalexin (targeting beta-hemolytic streptococci)
Cephalexin is appropriate for nonpurulent cellulitis because beta-hemolytic streptococci are the predominant cause and cephalexin provides reliable coverage. Trimethoprim-sulfamethoxazole targets MRSA and is added mainly for purulent infections; metronidazole and nitrofurantoin do not cover skin streptococci.
A 55-year-old man without diabetes or known cardiovascular disease has an LDL of 175 mg/dL. The nurse practitioner is deciding on lipid management. What is the most appropriate first step in implementing therapy?
- Begin a bile acid sequestrant alone
- Start a fibrate as initial monotherapy
- Defer all therapy and recheck lipids in 5 years
- Begin a moderate- to high-intensity statin along with lifestyle changes
Correct answer: Begin a moderate- to high-intensity statin along with lifestyle changes
A statin combined with lifestyle change is the most appropriate first step because an LDL of 175 mg/dL falls in the 160 to 189 range, and after estimating 10-year ASCVD risk a statin is the most effective LDL-lowering therapy for this patient. Fibrates and bile acid sequestrants are not first-line for primary LDL reduction, and deferring care leaves an elevated LDL untreated.
A nurse practitioner obtains informed consent before placing a contraceptive implant in a competent adult. Which element is essential to a valid informed consent discussion?
- Having the patient sign the form before any explanation is given
- Documenting that the procedure is routine so details can be omitted
- Disclosing the risks, benefits, and reasonable alternatives so the patient can make a voluntary decision
- Obtaining consent only from a family member present at the visit
Correct answer: Disclosing the risks, benefits, and reasonable alternatives so the patient can make a voluntary decision
Valid informed consent requires disclosing the risks, benefits, and reasonable alternatives to a patient with decision-making capacity so the choice is voluntary and informed. Signing before explanation, substituting a family member for a capable adult, or omitting details because a procedure is routine all violate the standard.
A nurse practitioner caring for a 3-year-old with acute otitis media chooses observation rather than immediate antibiotics. Which condition makes the watchful-waiting approach appropriate?
- A nonsevere unilateral infection with reliable follow-up and shared decision-making
- Severe ear pain lasting more than 48 hours in an ill-appearing child
- Otorrhea from a ruptured tympanic membrane
- Bilateral disease with a temperature of 39.5 degrees Celsius
Correct answer: A nonsevere unilateral infection with reliable follow-up and shared decision-making
Observation with a safety-net plan is appropriate for a child 24 months or older with nonsevere unilateral acute otitis media when reliable follow-up and shared decision-making are assured. Bilateral disease with high fever, otorrhea, or severe persistent pain warrants antibiotics, so those scenarios are not candidates for watchful waiting.
A nurse practitioner is teaching a patient newly diagnosed with type 2 diabetes who is starting metformin. Which counseling point helps the patient anticipate the most common early side effect and improve tolerance?
- Take it on an empty stomach to speed its effect
- Take metformin with meals and expect gastrointestinal upset that often eases over time
- Expect frequent hypoglycemia and carry glucose tablets at all times
- Anticipate significant weight gain in the first month
Correct answer: Take metformin with meals and expect gastrointestinal upset that often eases over time
Taking metformin with meals and being prepared for transient gastrointestinal upset that usually improves with time supports adherence, and starting low and titrating slowly helps further. Metformin alone rarely causes hypoglycemia and tends to be weight-neutral, and taking it on an empty stomach worsens stomach upset.
A patient with non-valvular atrial fibrillation has been on warfarin for three months. The most recent INR is 2.6, and the patient reports no bleeding or new bruising. How should the nurse practitioner evaluate this result?
- The INR is subtherapeutic and the warfarin dose should be increased
- The INR shows the patient should be switched off warfarin entirely
- The INR is supratherapeutic and warfarin should be held for two days
- The INR is within the target range and the current dose should be continued
Correct answer: The INR is within the target range and the current dose should be continued
An INR of 2.6 is within the target range for non-valvular atrial fibrillation, so the current dose should be continued. The goal INR for non-valvular AF is 2.5 (range 2.0 to 3.0); a value of 2.6 sits squarely in range, indicating effective and safe anticoagulation. Once the INR is stable and in range, monitoring can be extended to roughly every four weeks rather than weekly.
A nurse practitioner is teaching a patient how warfarin therapy will be monitored. Which laboratory test should be described as the test used to evaluate the therapeutic effect and guide dosing?
- Anti-Xa level
- Platelet count
- Activated partial thromboplastin time (aPTT)
- International normalized ratio (INR) derived from the prothrombin time
Correct answer: International normalized ratio (INR) derived from the prothrombin time
The international normalized ratio (INR), derived from the prothrombin time, is the test used to monitor warfarin and guide dose adjustments. Warfarin inhibits vitamin K-dependent clotting factors, prolonging the prothrombin time, which is standardized as the INR. The aPTT monitors unfractionated heparin, and anti-Xa levels monitor low-molecular-weight heparin or direct Xa inhibitors, not warfarin.
A patient with a bileaflet mechanical mitral valve returns for warfarin follow-up with an INR of 2.2. The patient is asymptomatic. How should the nurse practitioner evaluate and respond to this finding?
- The INR is below the target range for a mechanical mitral valve and the dose should be increased
- The INR indicates the patient no longer needs anticoagulation
- The INR is dangerously high and warfarin should be discontinued
- The INR is therapeutic for this valve and no change is needed
Correct answer: The INR is below the target range for a mechanical mitral valve and the dose should be increased
An INR of 2.2 is below the target range for a mechanical mitral valve, so the warfarin dose should be increased and the INR rechecked. Mechanical mitral valves require a higher target INR of 3.0 (range 2.5 to 3.5) because of greater thrombogenic risk in the mitral position. A value of 2.2 leaves the patient inadequately protected from valve thrombosis and embolic stroke.
A patient started on warfarin three days ago calls reporting that home INR is 1.3. How should the nurse practitioner interpret this early result?
- The medication has failed and should be changed to a different anticoagulant
- The patient is overdosed and warfarin must be held immediately
- The INR confirms the target has been reached and monitoring can move to monthly
- This is an expected early value because full anticoagulant effect takes several days, and dosing continues with frequent INR checks
Correct answer: This is an expected early value because full anticoagulant effect takes several days, and dosing continues with frequent INR checks
An INR of 1.3 three days into therapy is an expected early value because warfarin's full anticoagulant effect takes about five to seven days to develop. Evaluation of warfarin response must account for the delayed depletion of existing clotting factors; INR should be checked at least weekly during initiation and the dose titrated toward the target before extending intervals. It does not represent treatment failure.
A patient on stable warfarin therapy presents with an INR of 5.8 but no signs of bleeding. According to standard evaluation of an over-anticoagulated patient, what is the most appropriate next step?
- Transfuse fresh frozen plasma
- Administer intravenous vitamin K immediately
- Hold one or two warfarin doses and recheck the INR, adjusting the maintenance dose
- Continue the current dose because there is no bleeding
Correct answer: Hold one or two warfarin doses and recheck the INR, adjusting the maintenance dose
For an INR of 5.8 without bleeding, the appropriate response is to hold one or two warfarin doses, recheck the INR, and reduce the maintenance dose. An elevated INR without hemorrhage is managed by interrupting the drug and letting the INR drift down; routine vitamin K or plasma is reserved for higher INRs with bleeding or urgent reversal needs. Simply continuing the dose leaves the patient at high bleeding risk.
A nurse practitioner wants to systematically evaluate whether a patient's treatment plan is working. Which approach best reflects evaluation of treatment plan effectiveness?
- Documenting the patient's adherence without reviewing clinical outcomes
- Comparing the patient's current measurable outcomes against the goals established in the plan
- Asking only whether the patient took the prescribed medication
- Reordering all baseline diagnostic tests regardless of the goals set
Correct answer: Comparing the patient's current measurable outcomes against the goals established in the plan
Evaluating treatment plan effectiveness means comparing the patient's current measurable outcomes against the goals that were established in the plan. The evaluation step of the nursing process determines the degree to which expected outcomes were met, using objective data such as lab values, vital signs, and symptom resolution. Adherence is relevant but is only one input; the central question is whether the stated goals were achieved.
A nurse practitioner reviews a patient whose goal was a pain score below 4 within two weeks; the patient now reports a pain score of 2. How should this outcome be documented in the evaluation step?
- Outcome met, with the current plan continued and monitored
- Outcome unmet, requiring a completely new plan
- Outcome unable to be evaluated
- Outcome irrelevant because pain is subjective
Correct answer: Outcome met, with the current plan continued and monitored
Because the patient's pain score of 2 falls below the target of 4 within the time frame, the outcome is met and the current plan should be continued and monitored. Evaluation compares actual results to the specific, measurable goal that was set; when the criterion is satisfied, the plan is judged effective. A new plan is reserved for outcomes that are not met.
During evaluation of a care plan, a patient has not reached the expected outcome despite full adherence and adequate time on therapy. What is the most appropriate conclusion?
- The plan requires reassessment and modification of interventions
- The patient is non-compliant and should be discharged
- Evaluation should be postponed indefinitely
- The original diagnosis is automatically wrong
Correct answer: The plan requires reassessment and modification of interventions
When an outcome is not met despite adherence and adequate time, the plan should be reassessed and the interventions modified. The evaluation step feeds back into the nursing process: an unmet outcome triggers reassessment of the patient, possible revision of the diagnosis or goals, and adjustment of interventions. Labeling the patient non-compliant ignores that adherence was confirmed.
A patient with type 2 diabetes started metformin three months ago. The baseline A1C was 8.4% and the repeat A1C is now 7.6%. According to current evaluation of glycemic response, what is the appropriate interpretation?
- The A1C has improved but remains above target, so therapy should be intensified
- The A1C indicates metformin should be stopped
- The A1C result should be ignored until six months have passed
- The A1C is at goal and no further action is needed
Correct answer: The A1C has improved but remains above target, so therapy should be intensified
The A1C has improved from 8.4% to 7.6% but remains above the general target of under 7%, so therapy should be intensified. Current standards evaluate A1C every three months while therapy is being adjusted; a value of 7.5% or higher signals the need to reinforce lifestyle measures and add or intensify medication. Stopping an effective agent or ignoring the result would both be inappropriate.
A nurse practitioner explains how a patient's response to diabetes treatment will be tracked over time. Which test best reflects average glucose control over the preceding two to three months?
- Hemoglobin A1C
- Fasting plasma glucose
- Urine ketones
- Random capillary glucose
Correct answer: Hemoglobin A1C
Hemoglobin A1C best reflects average glucose control over the preceding two to three months because it measures the percentage of glycated hemoglobin, which mirrors the lifespan of red blood cells. This makes A1C the standard test for evaluating the response to a diabetes treatment plan. Fasting and random glucose capture only a single moment, and urine ketones assess for diabetic ketoacidosis, not chronic control.
A patient on stable diabetes therapy has had two consecutive A1C values at 6.6% over the past year. How often should the A1C now be evaluated according to current monitoring intervals?
- Every six months
- Every month
- Every three months
- Only when symptoms appear
Correct answer: Every six months
For a patient who is at goal and stable on unchanging therapy, A1C should be evaluated every six months. The recommended interval is every three to six months until stable, then every six months once goals are met and therapy is not changing. Monthly testing is unnecessary and A1C reflects months of glycemia, so symptom-triggered testing alone is inadequate for chronic monitoring.
A patient with hypertension has been on lifestyle modification and a single antihypertensive for three months. Average home blood pressure is now 138/86 mmHg. Based on current targets, how should the nurse practitioner evaluate and modify the plan?
- Blood pressure remains above target, so the regimen should be intensified by increasing the dose or adding a second agent
- No change is needed until the patient reaches 160/100 mmHg
- The plan is meeting goal and should continue unchanged
- Antihypertensive therapy should be stopped because the patient feels well
Correct answer: Blood pressure remains above target, so the regimen should be intensified by increasing the dose or adding a second agent
Because the average blood pressure of 138/86 mmHg remains above the target of less than 130/80 mmHg, the regimen should be intensified by increasing the dose or adding a second agent from a different class. Current guidelines set a universal goal under 130/80 mmHg and recommend modifying therapy when that goal is not met after an adequate trial. Stopping therapy or waiting for a much higher reading would leave the patient under-treated.
A nurse practitioner is teaching a clinic team about when to modify a hypertension treatment plan. Which scenario most clearly indicates the plan should be changed?
- Blood pressure has dropped to 118/76 mmHg with no symptoms
- Home readings consistently confirm blood pressure at or above 130/80 mmHg despite adherence to the current regimen
- The patient reports occasional missed doses and readings are at goal
- A single elevated office reading in an otherwise controlled patient
Correct answer: Home readings consistently confirm blood pressure at or above 130/80 mmHg despite adherence to the current regimen
Consistently elevated home readings at or above 130/80 mmHg despite adherence indicate the plan should be modified. Treatment modification is driven by confirmed out-of-goal blood pressure, not by an isolated office reading or by occasional missed doses when readings are at goal. A reading of 118/76 mmHg without symptoms reflects good control, not a reason to change therapy.
A patient was started on lisinopril for hypertension. At follow-up, blood pressure is improved but the patient reports a persistent dry cough. How should the nurse practitioner evaluate this response and modify the plan?
- Continue lisinopril and reassure the patient the cough is unrelated
- Recognize the cough as a likely adverse effect of the ACE inhibitor and consider switching to an ARB
- Stop all antihypertensive therapy
- Add a second antihypertensive to mask the cough
Correct answer: Recognize the cough as a likely adverse effect of the ACE inhibitor and consider switching to an ARB
The persistent dry cough should be recognized as a likely adverse effect of the ACE inhibitor, prompting a switch to an angiotensin receptor blocker. Evaluation of a treatment plan includes assessing tolerability, not just efficacy; ACE-inhibitor cough is a well-known class effect that resolves after switching to an ARB, which provides comparable blood pressure control without the cough.
A patient with heart failure with reduced ejection fraction returns two weeks after starting a loop diuretic. The patient reports less dyspnea and has lost 4 pounds, with reduced ankle edema. How should the nurse practitioner evaluate this response?
- The patient is responding appropriately, and the plan should continue with ongoing monitoring of weight, symptoms, and renal function
- The patient should immediately double the diuretic dose
- The diuretic is ineffective and should be discontinued
- The improvement is unrelated to the diuretic
Correct answer: The patient is responding appropriately, and the plan should continue with ongoing monitoring of weight, symptoms, and renal function
Reduced dyspnea, weight loss, and decreased edema indicate the patient is responding appropriately to the diuretic, so the plan should continue with monitoring of daily weight, symptoms, electrolytes, and renal function. Evaluation in heart failure relies on these congestion markers; favorable trends confirm effectiveness. Doubling the dose without a clear need risks volume depletion and electrolyte disturbance.
A patient with persistent asthma using a low-dose inhaled corticosteroid completes an Asthma Control Test with a score of 16. How should the nurse practitioner evaluate control and adjust the plan?
- Asthma is well controlled and therapy can be stepped down
- Asthma is not adequately controlled, so adherence and technique should be reviewed and therapy stepped up
- The score is meaningless for evaluating control
- Therapy should be stopped because the patient is using a controller
Correct answer: Asthma is not adequately controlled, so adherence and technique should be reviewed and therapy stepped up
An Asthma Control Test score of 16 indicates asthma is not adequately controlled, so inhaler technique and adherence should be reviewed and controller therapy stepped up. A total score of 19 or less signals inadequate control; evaluation should first confirm correct technique and adherence before escalating treatment. Stepping down or stopping therapy would worsen control.
A patient treated for community-acquired pneumonia returns after 72 hours of oral antibiotics still febrile, with worsening dyspnea and no improvement. How should the nurse practitioner evaluate this clinical response?
- The patient should simply take more of the same antibiotic
- This represents inadequate response to therapy and warrants reassessment, including possible resistant organism, complication, or alternative diagnosis
- The treatment is working and the patient should finish the course
- Antibiotics always take two weeks to work, so no action is needed
Correct answer: This represents inadequate response to therapy and warrants reassessment, including possible resistant organism, complication, or alternative diagnosis
Persistent fever and worsening dyspnea after 72 hours indicate an inadequate response to therapy, warranting reassessment for a resistant organism, a complication such as empyema, or an alternative diagnosis. Most patients with community-acquired pneumonia show clinical improvement within 48 to 72 hours; failure to improve triggers re-evaluation of the plan rather than continuing an ineffective regimen.
A patient started on levothyroxine for hypothyroidism six weeks ago returns for evaluation. Which laboratory result best indicates the adequacy of the replacement dose?
- Total T4 only
- Reverse T3
- Thyroid-stimulating hormone (TSH)
- Thyroid peroxidase antibodies
Correct answer: Thyroid-stimulating hormone (TSH)
Thyroid-stimulating hormone (TSH) best indicates the adequacy of levothyroxine replacement and is the primary test for monitoring response, typically rechecked about six to eight weeks after a dose change. A normalized TSH confirms the dose is appropriate; antibody titers diagnose the cause of disease but do not guide dosing, and reverse T3 is not used for routine monitoring.
A patient on a statin returns for follow-up lipid evaluation. Baseline LDL was 168 mg/dL and the repeat LDL is now 95 mg/dL, with no muscle symptoms. How should the nurse practitioner evaluate this response?
- The patient is responding well, with a meaningful LDL reduction and no adverse effects, so the regimen should continue
- A fibrate should immediately replace the statin
- The statin has failed and should be stopped
- The LDL change is too small to matter
Correct answer: The patient is responding well, with a meaningful LDL reduction and no adverse effects, so the regimen should continue
A drop in LDL from 168 to 95 mg/dL with no muscle symptoms shows the patient is responding well, so the statin regimen should continue. Evaluation of lipid-lowering therapy assesses both the magnitude of LDL reduction and tolerability; a substantial reduction without myalgia indicates an effective, well-tolerated plan. Stopping or switching therapy is unwarranted.
A patient treated for major depressive disorder has been on an SSRI for two weeks and reports no improvement in mood. How should the nurse practitioner evaluate this finding?
- The patient should stop the medication abruptly
- This is an expected early time point because antidepressants typically take four to six weeks for full effect, so the plan should continue with monitoring
- The diagnosis must be incorrect
- The medication has failed and must be switched today
Correct answer: This is an expected early time point because antidepressants typically take four to six weeks for full effect, so the plan should continue with monitoring
Two weeks without mood improvement is an expected early time point because SSRIs typically require four to six weeks for full therapeutic effect, so the plan should continue with monitoring and support. Evaluation must account for the expected onset of action before judging an antidepressant a failure; abrupt discontinuation can cause withdrawal symptoms and is inappropriate.
A patient with chronic kidney disease started on an ACE inhibitor returns for evaluation. The serum creatinine has risen from 1.2 to 1.4 mg/dL, a 17% increase, and potassium is normal. How should the nurse practitioner evaluate this change?
- The creatinine change confirms the drug is ineffective
- The kidney function is improving
- This is an unacceptable rise requiring immediate discontinuation
- This degree of creatinine rise is acceptable and the ACE inhibitor can be continued with continued monitoring
Correct answer: This degree of creatinine rise is acceptable and the ACE inhibitor can be continued with continued monitoring
A creatinine rise of about 17% with normal potassium is acceptable, so the ACE inhibitor can be continued with monitoring. A rise of up to roughly 30% from baseline that stabilizes is expected with ACE inhibitors and reflects hemodynamic effects, not nephrotoxicity. Evaluation considers the magnitude of change and potassium before deciding whether to continue or stop the drug.
A patient with iron deficiency anemia has been taking oral ferrous sulfate for four weeks. Which finding best indicates an early, appropriate response to therapy?
- A decrease in mean corpuscular volume below normal
- No change in hemoglobin is expected ever
- A rise in the reticulocyte count
- An immediate normalization of ferritin within days
Correct answer: A rise in the reticulocyte count
A rise in the reticulocyte count is the earliest indicator of an appropriate response to oral iron, usually appearing within the first one to two weeks as the marrow ramps up red cell production. Hemoglobin then rises over several weeks and ferritin replenishes more slowly. Evaluation of iron therapy looks for this reticulocyte response first, followed by hemoglobin recovery.
A child treated for acute otitis media with amoxicillin returns after three days with continued fever and ear pain. How should the nurse practitioner evaluate this response and modify the plan?
- Add a decongestant and continue the same antibiotic indefinitely
- Stop all antibiotics and observe
- Recognize treatment failure and change to a beta-lactamase-stable agent such as amoxicillin-clavulanate
- Continue the same antibiotic because three days is too soon to judge
Correct answer: Recognize treatment failure and change to a beta-lactamase-stable agent such as amoxicillin-clavulanate
Persistent fever and ear pain after 48 to 72 hours of amoxicillin indicate treatment failure, so therapy should be changed to a beta-lactamase-stable agent such as amoxicillin-clavulanate. Evaluation of antibiotic response uses the expected window of clinical improvement; lack of improvement signals a likely resistant organism and warrants modifying the antibiotic.
A patient on long-term inhaled corticosteroid therapy for asthma is being evaluated for adverse effects. Which monitoring action is most appropriate to assess a recognized local side effect?
- Ordering routine chest CT scans
- Checking serum potassium at every visit
- Measuring 24-hour urine cortisol monthly
- Inspecting the oropharynx for oral candidiasis
Correct answer: Inspecting the oropharynx for oral candidiasis
Inspecting the oropharynx for oral candidiasis is the most appropriate action because oral thrush is a recognized local adverse effect of inhaled corticosteroids. Evaluation of therapy includes monitoring for predictable side effects; reinforcing spacer use and mouth rinsing after dosing helps prevent it. Routine serum potassium, chest CT, and monthly urine cortisol are not standard for this purpose.
A patient started on a thiazide diuretic for hypertension returns in three weeks. Blood pressure is improved, but serum potassium is now 3.1 mEq/L. How should the nurse practitioner evaluate and respond?
- Stop monitoring electrolytes going forward
- Double the thiazide dose
- Ignore the potassium because blood pressure improved
- Recognize thiazide-induced hypokalemia and modify the plan with potassium repletion or a potassium-sparing strategy
Correct answer: Recognize thiazide-induced hypokalemia and modify the plan with potassium repletion or a potassium-sparing strategy
A potassium of 3.1 mEq/L reflects thiazide-induced hypokalemia, so the plan should be modified with potassium repletion or a potassium-sparing approach. Evaluating a treatment plan includes monitoring for metabolic adverse effects; thiazides commonly lower potassium, and uncorrected hypokalemia raises arrhythmia risk. Ignoring the value or increasing the dose would worsen the imbalance.
A patient with hypertension on amlodipine returns reporting new bilateral ankle edema but otherwise good blood pressure control. How should the nurse practitioner evaluate this finding?
- The patient should restrict all fluids permanently
- The edema is a recognized dose-related adverse effect of the calcium channel blocker, prompting consideration of dose reduction or an alternative agent
- The edema is unrelated to any medication
- The edema indicates heart failure and the drug should continue unchanged
Correct answer: The edema is a recognized dose-related adverse effect of the calcium channel blocker, prompting consideration of dose reduction or an alternative agent
Bilateral ankle edema with otherwise good control is a recognized dose-related adverse effect of dihydropyridine calcium channel blockers like amlodipine, prompting consideration of a lower dose or an alternative agent. Evaluation weighs efficacy against tolerability; the edema is peripheral and not a sign of heart failure, so the plan can be adjusted to improve tolerability while maintaining control.
A patient with type 2 diabetes started on an SGLT2 inhibitor returns for evaluation reporting recurrent genital yeast infections. How should the nurse practitioner evaluate this development?
- It means the diabetes is now cured
- It is an unexpected reaction unrelated to the drug class
- It requires immediate hospitalization
- It is a recognized adverse effect of SGLT2 inhibitors that should be weighed against glycemic benefit when deciding whether to continue
Correct answer: It is a recognized adverse effect of SGLT2 inhibitors that should be weighed against glycemic benefit when deciding whether to continue
Recurrent genital yeast infections are a recognized adverse effect of SGLT2 inhibitors due to glucosuria, and evaluation involves weighing this against the glycemic and cardiorenal benefits when deciding whether to continue. Mycotic infections are common but usually manageable; the finding is expected for the class and informs shared decision-making, not hospitalization.
A patient on chronic warfarin therapy reports starting a new course of an antibiotic last week and now has an INR of 4.5. How should the nurse practitioner evaluate this change?
- The antibiotic could not affect the INR
- Warfarin should be permanently stopped
- The INR is at the desired target
- A drug interaction likely potentiated warfarin, so the dose should be held or reduced and the INR rechecked
Correct answer: A drug interaction likely potentiated warfarin, so the dose should be held or reduced and the INR rechecked
A jump to an INR of 4.5 after starting an antibiotic likely reflects a drug interaction that potentiated warfarin, so the dose should be held or reduced and the INR rechecked. Many antibiotics inhibit warfarin metabolism or disrupt gut vitamin K, raising the INR. Evaluation of anticoagulation must consider recent medication changes; permanent discontinuation is not indicated for a transient interaction.
A patient with gout was started on allopurinol three months ago for urate-lowering therapy. Which laboratory value best indicates the therapy is meeting its goal?
- Elevated serum creatinine
- Elevated erythrocyte sedimentation rate
- Serum uric acid below 6 mg/dL
- Normal random glucose
Correct answer: Serum uric acid below 6 mg/dL
A serum uric acid below 6 mg/dL best indicates allopurinol is meeting its urate-lowering goal. Evaluation of urate-lowering therapy targets a serum urate under 6 mg/dL to dissolve crystal deposits and reduce flares over time. The sedimentation rate, glucose, and creatinine do not measure the success of urate lowering.
A nurse practitioner evaluates a hypertensive patient whose blood pressure is now well controlled at 124/78 mmHg on two agents, with no adverse effects. What is the appropriate evaluation outcome?
- The blood pressure is too low and a dose must be halved
- Therapy should be stopped because the goal was reached
- The goal is met and the current regimen should be maintained with routine follow-up
- The patient should add a third agent for safety
Correct answer: The goal is met and the current regimen should be maintained with routine follow-up
With blood pressure controlled at 124/78 mmHg and no adverse effects, the goal is met and the current regimen should be maintained with routine follow-up. The target is under 130/80 mmHg, getting as close to 120/80 as tolerated; a value of 124/78 reflects success. Adding or removing therapy is unnecessary, and 124/78 is not too low in an asymptomatic patient.
A patient with type 2 diabetes started on a regimen three months ago has an A1C that increased from 7.2% to 8.1%. The patient admits to frequently missing doses. How should the nurse practitioner evaluate this result before modifying medication?
- Conclude the medication is ineffective and discontinue it
- Evaluate adherence and barriers first, because the worsening A1C may reflect missed doses rather than an ineffective regimen
- Repeat the A1C the next day
- Immediately add a new injectable medication without further discussion
Correct answer: Evaluate adherence and barriers first, because the worsening A1C may reflect missed doses rather than an ineffective regimen
Because the patient reports frequently missing doses, adherence and barriers should be evaluated first, since the rising A1C may reflect missed doses rather than an ineffective regimen. Proper evaluation distinguishes true treatment failure from non-adherence before escalating therapy. Repeating A1C the next day is pointless, as it reflects months of glycemia, and adding medication without addressing adherence may not help.
A patient with COPD on long-acting bronchodilator therapy returns reporting two exacerbations requiring oral steroids in the past year despite good adherence. How should the nurse practitioner evaluate this and modify the plan?
- Recognize that frequent exacerbations indicate inadequate control, warranting step-up of therapy per current guidelines
- Continue the same therapy because the patient is adherent
- Tell the patient exacerbations cannot be reduced
- Stop all inhalers
Correct answer: Recognize that frequent exacerbations indicate inadequate control, warranting step-up of therapy per current guidelines
Two exacerbations requiring oral steroids in a year despite adherence indicate inadequate control, warranting a step-up in maintenance therapy. Evaluation of COPD management uses exacerbation frequency as a key outcome; a high exacerbation burden signals the plan should be escalated, for example by adding an inhaled corticosteroid in appropriate patients. Continuing unchanged therapy ignores the unmet goal.
A patient with hypothyroidism on levothyroxine returns with a TSH of 0.1 mIU/L and reports palpitations and insomnia. How should the nurse practitioner evaluate and modify the plan?
- The TSH result should be ignored
- A second thyroid medication should be added
- The patient is over-replaced, indicating the levothyroxine dose should be reduced
- The dose is appropriate and should continue
Correct answer: The patient is over-replaced, indicating the levothyroxine dose should be reduced
A suppressed TSH of 0.1 mIU/L with palpitations and insomnia indicates over-replacement, so the levothyroxine dose should be reduced. Evaluation of thyroid replacement uses TSH plus symptoms; a low TSH with hyperthyroid symptoms means the dose is too high, which risks atrial fibrillation and bone loss. Adding another agent or ignoring the value would be unsafe.
A pregnant patient with gestational diabetes has been following medical nutrition therapy. Her fasting glucose logs remain above target on most days over two weeks. How should the nurse practitioner evaluate this and modify the plan?
- Advise the patient to skip meals to lower glucose
- Recognize that nutrition therapy has not met glycemic goals, warranting initiation of pharmacologic therapy such as insulin
- Stop monitoring glucose
- Continue nutrition therapy alone indefinitely
Correct answer: Recognize that nutrition therapy has not met glycemic goals, warranting initiation of pharmacologic therapy such as insulin
Persistently elevated fasting glucose despite two weeks of nutrition therapy shows the lifestyle plan has not met glycemic goals, warranting pharmacologic therapy such as insulin. Evaluation in gestational diabetes uses home glucose logs against targets; failure to reach goals with nutrition alone is the trigger to add medication. Skipping meals is unsafe and does not address the underlying need for treatment.
A patient completed 12 weeks of direct-acting antiviral therapy for chronic hepatitis C. The nurse practitioner wants to confirm that the treatment cured the infection. Which result, obtained at least 12 weeks after the end of therapy, best confirms a successful response?
- An undetectable HCV RNA (sustained virologic response)
- A normal alanine aminotransferase (ALT) level
- A negative HCV antibody test
- A FibroScan showing no fibrosis
Correct answer: An undetectable HCV RNA (sustained virologic response)
An undetectable HCV RNA measured 12 or more weeks after completing therapy defines sustained virologic response (SVR12), the accepted marker of cure for hepatitis C. A normal ALT can occur even with persistent virus and does not prove eradication. The HCV antibody stays positive for life after exposure and reflects prior infection rather than active virus or cure, so it cannot be used to judge treatment response.
A patient with HIV started antiretroviral therapy four months ago. At the follow-up visit, which laboratory result most directly indicates that the regimen is working as intended?
- A normalized complete blood count
- A rising CD4 count alone
- An undetectable plasma HIV-1 viral load
- A negative HIV antibody/antigen screening test
Correct answer: An undetectable plasma HIV-1 viral load
An undetectable plasma HIV-1 viral load (viral suppression) is the primary measure of antiretroviral effectiveness, because the central treatment goal is to suppress replication below the limit of detection. The CD4 count is a marker of immune recovery and tends to lag behind viral suppression, so it is not the most direct early indicator. The HIV antibody/antigen test remains positive after seroconversion and never reverts with successful treatment.
A patient with COPD classified in GOLD Group E on LABA plus LAMA therapy returns after experiencing two moderate exacerbations in the past year. The blood eosinophil count is 340 cells/microliter. Based on current GOLD guidance, this evaluation most appropriately supports which change?
- Switching to a short-acting bronchodilator as needed only
- Adding an inhaled corticosteroid to the regimen
- Stopping all inhalers and starting oral theophylline
- De-escalating to a single long-acting bronchodilator
Correct answer: Adding an inhaled corticosteroid to the regimen
Adding an inhaled corticosteroid is supported because continued exacerbations on dual bronchodilator therapy combined with a blood eosinophil count of 300 cells/microliter or higher predicts corticosteroid responsiveness in current GOLD guidance. De-escalating therapy would be inappropriate when exacerbations persist. Eosinophil-guided evaluation, not symptom relief alone, drives this escalation decision.
A nurse practitioner evaluates a postmenopausal woman who has taken alendronate for two years for osteoporosis. Which finding best demonstrates that the bisphosphonate therapy is producing the intended effect?
- A stable or increased bone mineral density on follow-up DXA with no new fractures
- Resolution of chronic low back pain
- A reported increase in dietary calcium intake
- A serum calcium that has risen into the upper normal range
Correct answer: A stable or increased bone mineral density on follow-up DXA with no new fractures
A stable or increased bone mineral density on a repeat DXA scan together with the absence of new fragility fractures is the objective measure that osteoporosis treatment is working, since the goal is to preserve bone mass and prevent fractures. Back pain relief is nonspecific and not a reliable treatment endpoint. A rising serum calcium is not an expected or desired marker of bisphosphonate response.
A patient with chronic kidney disease has been on an ACE inhibitor and improved blood pressure control for one year. The nurse practitioner is evaluating whether kidney function is being preserved. Which trend over serial visits best indicates the plan is meeting its goal?
- A gradual rise in serum creatinine of 40 percent from baseline
- A stable estimated glomerular filtration rate with reduced albuminuria
- A serum potassium trending toward the low-normal range
- A urine albumin-to-creatinine ratio that is rising over time
Correct answer: A stable estimated glomerular filtration rate with reduced albuminuria
A stable estimated glomerular filtration rate combined with reduced albuminuria shows the renoprotective plan is achieving its aims of slowing decline and lowering protein loss. Rising albuminuria signals worsening kidney damage. A creatinine rise of 40 percent exceeds the acceptable early bump and indicates the regimen needs reassessment rather than confirming success.
A patient treated for gastroesophageal reflux disease has taken a once-daily proton pump inhibitor for eight weeks. At the evaluation visit, which patient-reported outcome best indicates the treatment plan has met its goal?
- Symptom-free days with resolution of heartburn and regurgitation
- The patient has switched to taking the PPI after meals
- Antacid use has increased to twice daily
- Heartburn now occurs only after large meals
Correct answer: Symptom-free days with resolution of heartburn and regurgitation
Resolution of heartburn and regurgitation with symptom-free days is the expected outcome of an adequate PPI course and confirms the plan is working. Persistent heartburn after meals and increased antacid use both signal an incomplete response that warrants reassessment of adherence, timing, or dosing. The goal of GERD therapy is symptom control and mucosal healing, not partial relief.
A patient diagnosed with major depressive disorder was started on an antidepressant and now returns at eight weeks. The baseline PHQ-9 score was 18 and is now 4. How should the nurse practitioner interpret this evaluation result?
- The patient has not responded and the medication should be stopped
- The patient requires immediate hospitalization
- The patient has achieved remission and the plan is effective
- The score is unreliable and should be disregarded
Correct answer: The patient has achieved remission and the plan is effective
A PHQ-9 score that has fallen from 18 to 4 indicates the depression is now in remission, since a score below 5 reflects minimal symptoms and confirms the antidepressant plan is effective. This is not treatment failure; failure would be little or no change in the score after an adequate trial. Using a validated symptom scale to track change over time is the standard way to evaluate response in depression.
A 6-year-old child was started on stimulant medication for ADHD. At the follow-up evaluation, which source of information most appropriately determines whether the treatment plan is meeting its functional goals?
- A single in-office observation of the child sitting still
- The child's self-report of feeling calmer
- The pharmacy refill date for the prescription
- Standardized teacher and parent behavior rating scales completed before and after treatment
Correct answer: Standardized teacher and parent behavior rating scales completed before and after treatment
Standardized teacher and parent rating scales compared before and after treatment provide the most valid evaluation of an ADHD response, because they capture behavior across the settings where impairment occurs. A brief office observation samples only one moment and can be misleading. Refill dates and a child's self-report do not reliably measure functional improvement in school and home performance.
A pregnant patient at 28 weeks who screened positive for anemia was started on oral iron supplementation. Which laboratory change at the follow-up visit best confirms an appropriate response to therapy?
- A rising hemoglobin and reticulocyte count
- An increased mean corpuscular volume above the normal range
- A falling serum ferritin
- A decreased transferrin saturation
Correct answer: A rising hemoglobin and reticulocyte count
A rising hemoglobin accompanied by an increased reticulocyte count confirms that iron supplementation is stimulating effective red blood cell production, the expected response in iron deficiency anemia. A falling ferritin or decreasing transferrin saturation would indicate continued iron depletion rather than recovery. Reticulocytosis is an early, reassuring sign that the marrow is responding before hemoglobin fully normalizes.
A toddler at the 18-month visit is being evaluated after dietary counseling for poor weight gain. The nurse practitioner reviews the growth chart. Which finding best indicates the intervention is succeeding?
- The parent reports the child eats only one meal a day
- The child has crossed upward toward a consistent weight-for-age percentile channel
- The head circumference has stopped increasing
- The child's weight percentile has dropped two major channels
Correct answer: The child has crossed upward toward a consistent weight-for-age percentile channel
A child moving upward toward and then tracking along a consistent weight-for-age percentile channel demonstrates catch-up growth and confirms the nutritional plan is effective. Dropping two major percentile channels indicates failure to thrive is worsening. Serial plotting on a standardized growth chart, not a single weight, is how growth response is evaluated over time.
A patient with persistent allergic rhinitis was started on a daily intranasal corticosteroid four weeks ago. At the evaluation visit, which outcome best demonstrates the treatment is working as intended?
- An increase in oral antihistamine use
- A negative skin-prick test panel
- A normal serum total IgE level
- Improved nasal congestion, sneezing, and rhinorrhea reported by the patient
Correct answer: Improved nasal congestion, sneezing, and rhinorrhea reported by the patient
Improvement in the patient's reported nasal congestion, sneezing, and runny nose is the appropriate measure of response to an intranasal corticosteroid, because symptom relief is the treatment goal for allergic rhinitis. Total IgE and skin-prick results reflect sensitization and do not change to gauge response. Rising antihistamine use would suggest inadequate control rather than success.
A patient with newly treated primary hypertension returns and home and office readings now average 124/78 mmHg on a single agent without adverse effects. According to current ACC/AHA guidance, how should the nurse practitioner evaluate this result?
- The medication should be stopped because the pressure is too low
- A second antihypertensive should be added because control is inadequate
- The reading should be ignored as a white-coat effect
- The blood pressure goal is met and the current plan should be continued
Correct answer: The blood pressure goal is met and the current plan should be continued
A consistent blood pressure below 130/80 mmHg meets the current ACC/AHA target for most adults, so the plan is effective and should be continued with ongoing monitoring. Adding a second agent is unnecessary when the goal is already achieved without side effects. A reading of 124/78 mmHg is well within the safe target range and does not justify stopping therapy.
A patient on warfarin is transitioned to a direct oral anticoagulant (apixaban) for atrial fibrillation. At the evaluation visit, what is the most appropriate way to confirm the regimen is being managed correctly?
- Check the INR and adjust the dose to a target of 2 to 3
- Order weekly prothrombin times
- Measure the eosinophil count to gauge response
- Assess adherence, renal function, and bleeding signs rather than routine INR
Correct answer: Assess adherence, renal function, and bleeding signs rather than routine INR
For a direct oral anticoagulant such as apixaban, evaluation centers on adherence, periodic renal function, and monitoring for bleeding, because these drugs do not require or respond to routine INR monitoring. Checking an INR to a target of 2 to 3 applies only to warfarin and is not a valid measure of apixaban therapy. Confusing the two monitoring strategies is a common error to avoid.
An older adult on five chronic medications returns for a periodic medication review. Which evaluation finding most strongly indicates the regimen needs modification rather than continuation?
- All prescriptions were refilled on time
- The patient reports no new symptoms since the last visit
- A medication is no longer matched to an active indication or is causing a new adverse effect
- The patient prefers once-daily dosing
Correct answer: A medication is no longer matched to an active indication or is causing a new adverse effect
Identifying a medication that no longer has an active indication or that is producing a new adverse effect is the key evaluation trigger for deprescribing or modification, especially in older adults at risk for polypharmacy harms. Timely refills and patient dosing preferences do not by themselves justify a change. A structured review compares each drug against its current indication, benefit, and risk.
A child who completed the recommended hepatitis B vaccine series as part of an evaluation for healthcare training needs documented immunity. Which laboratory result confirms an adequate response to the vaccine?
- A positive hepatitis B core antibody (anti-HBc)
- A normal serum alanine aminotransferase
- A positive hepatitis B surface antigen (HBsAg)
- A hepatitis B surface antibody (anti-HBs) level of 10 mIU/mL or greater
Correct answer: A hepatitis B surface antibody (anti-HBs) level of 10 mIU/mL or greater
A hepatitis B surface antibody (anti-HBs) level of at least 10 mIU/mL confirms a protective immune response to the vaccine series. A positive surface antigen indicates active infection, not vaccine response, and a positive core antibody reflects natural infection rather than immunization. A normal liver enzyme says nothing about whether protective immunity was achieved.
A patient with newly diagnosed primary open-angle glaucoma was started on a topical prostaglandin analog eye drop. At the follow-up visit, which objective measurement best determines whether the eye drop is achieving its therapeutic goal?
- A reduction in intraocular pressure compared with the pretreatment baseline
- An improvement in distance visual acuity on the eye chart
- The patient's report that the eye no longer feels irritated
- The absence of redness when the eye is inspected
Correct answer: A reduction in intraocular pressure compared with the pretreatment baseline
A reduction in intraocular pressure from the pretreatment baseline is the measure that confirms the prostaglandin analog is working, because lowering intraocular pressure is the central goal of glaucoma therapy and the only modifiable risk factor that slows optic nerve damage. Visual acuity often stays stable in early glaucoma and does not track treatment response, and comfort or absence of redness reflects tolerability rather than pressure control. Evaluation therefore relies on serial tonometry against the established target pressure.
A patient with epilepsy maintained on phenytoin returns for evaluation reporting two breakthrough seizures this month, and the trough phenytoin level is 6 mcg/mL. How should the nurse practitioner interpret and act on this evaluation finding?
- The level is below the therapeutic range, supporting a dose increase with repeat level monitoring
- The level is toxic, so the next several doses should be held
- The level is therapeutic, so the seizures must be unrelated to the medication
- The level is irrelevant because seizure frequency alone guides dosing
Correct answer: The level is below the therapeutic range, supporting a dose increase with repeat level monitoring
A trough phenytoin level of 6 mcg/mL falls below the usual therapeutic range of 10 to 20 mcg/mL, which explains the breakthrough seizures and supports increasing the dose with a repeat level afterward. Evaluating an antiepileptic plan combines the clinical outcome, seizure frequency, with the serum drug concentration, because subtherapeutic levels are a common and correctable cause of recurrent seizures. The level is not toxic and is highly relevant, so simply attributing the seizures elsewhere or holding doses would be inappropriate.
A patient with severe hypertriglyceridemia was started on fenofibrate to reduce pancreatitis risk. At the follow-up lipid evaluation, which result most directly indicates the therapy is meeting its primary goal?
- A reduction in the hemoglobin A1C
- An increase in the total cholesterol level
- A rise in the LDL cholesterol level
- A substantial fall in the serum triglyceride level
Correct answer: A substantial fall in the serum triglyceride level
A substantial fall in the serum triglyceride level is the result that confirms fenofibrate is meeting its primary goal, because fibrates are prescribed mainly to lower very high triglycerides and reduce the risk of acute pancreatitis. Evaluation of this plan focuses on the triglyceride trend rather than LDL, since fibrates can modestly raise LDL and that change does not signal failure of the intended effect. Total cholesterol and A1C are not the targets of fibrate therapy and do not measure its success.
A patient hospitalized and then discharged for heart failure with reduced ejection fraction returns for evaluation after dose optimization of guideline-directed therapy. Serial NT-proBNP values have fallen markedly from the level measured during the acute decompensation. How should the nurse practitioner interpret this trend?
- The falling NT-proBNP suggests reduced cardiac wall stress and a favorable response to therapy
- The falling NT-proBNP indicates worsening heart failure requiring hospitalization
- The falling NT-proBNP means the heart failure diagnosis was incorrect
- The NT-proBNP trend cannot be used to evaluate heart failure therapy
Correct answer: The falling NT-proBNP suggests reduced cardiac wall stress and a favorable response to therapy
A marked downward trend in NT-proBNP reflects reduced ventricular wall stress and indicates a favorable response to optimized heart failure therapy. Natriuretic peptides rise with the cardiac stretch of decompensation and fall as congestion and filling pressures improve, so a declining serial value, interpreted alongside symptoms and weight, supports that the plan is working. A falling level signals improvement rather than worsening and does not call the original diagnosis into question.
A patient on long-term suppressive therapy with tenofovir for chronic hepatitis B returns for an evaluation visit. Which laboratory result best demonstrates that the antiviral therapy is achieving viral suppression?
- An undetectable or markedly reduced serum hepatitis B virus DNA level
- A positive hepatitis B surface antibody
- A normal serum alanine aminotransferase alone
- A negative hepatitis B core antibody
Correct answer: An undetectable or markedly reduced serum hepatitis B virus DNA level
An undetectable or markedly reduced serum hepatitis B virus DNA level best demonstrates that antiviral therapy is suppressing viral replication, which is the central goal of treating chronic hepatitis B. A normalized alanine aminotransferase is supportive but can be normal even with ongoing replication, so it is not the most direct marker of virologic response. Surface antibody and core antibody describe immune status and prior exposure rather than the response of active infection to therapy.
A patient with frequent migraine was started on a daily preventive medication and asked to keep a headache diary. At the three-month evaluation, which finding best indicates the preventive plan is effective?
- A clinically meaningful reduction in the number of monthly headache days from baseline
- A change in the location of the headache pain
- A faster response of acute attacks to as-needed triptan therapy
- An increase in the number of rescue medication doses used per week
Correct answer: A clinically meaningful reduction in the number of monthly headache days from baseline
A clinically meaningful reduction in the number of monthly headache days compared with the pretreatment baseline is the standard measure that migraine prevention is working, since the goal of prophylaxis is to lower attack frequency over time. Evaluation relies on the headache diary to compare monthly headache days before and after starting therapy, typically judged after an adequate two-to-three-month trial. Faster acute relief reflects abortive treatment rather than prevention, and rising rescue use signals inadequate, not effective, prophylaxis.

FNP Question of the DayNew daily

1 of 380+ free questions — a new one every day

When assessing for appendicitis, which sign is most indicative of the condition?

Pick an answer to see the explanation

Click Start Test above to launch a full-length FNP practice test weighted exactly like the real ANCC exam, or drill a single domain — Assessment, Diagnosis, Planning, Implementation, or Evaluation. Every question includes a clear rationale so you learn the clinical reasoning, not just the answer.

The FNP-BC exam — officially the Family Nurse Practitioner-Board Certified exam — is administered by the American Nurses Credentialing Center (ANCC) and earns you the FNP-BC credential.^[1] These free FNP practice questions and test prep mirror the current ANCC blueprint so you practice the way the real exam is built.^[4] For deeper review, pair these with our free study guide, flashcards.

What Is on the FNP-BC Exam?

The ANCC FNP-BC exam covers five domains that follow the nursing process: Implementation (29%), Assessment (19%), Planning (19%), Diagnosis (17%), and Evaluation (15%).^[2]

Implementation is by far the largest because ANCC integrates clinical care with professional role, ethics, legal/regulatory issues, and healthcare systems. Our full practice test is weighted to match:

Assessment19% · ≈28 Qs

Practice Questions by Domain

Use Start Test for a full weighted FNP-BC simulation, or open the hub and pick a single domain to drill your weak area. After each full exam, your results show a per-domain breakdown so you know exactly where to focus — most candidates need the most reps on Implementation and the professional-role content that distinguishes ANCC from AANP.

What Are the Requirements to Take the FNP-BC Exam?

To take the FNP-BC exam, you need a current, active, unencumbered RN license in a U.S. state or territory plus a completed FNP-focused master’s (MSN), post-graduate certificate, or doctorate (DNP) from a CCNE- or ACEN-accredited program.^[1]

The program must include at least 500 faculty-supervised primary-care clinical hours and separate graduate courses in advanced pathophysiology, pharmacology, and health assessment. Effective January 1, 2026, you must pass the exam within 5 years of completing your program.

How Do You Register for the FNP-BC Exam?

You register for the FNP-BC exam online through the ANCC certification portal at nursingworld.org, submitting proof of RN licensure plus official transcripts.^[2]

Once ANCC verifies eligibility, you receive an Authorization to Test and schedule the exam at a Prometric center (or remote proctoring where offered) within your 90-day window. The standard fee is $395, reduced to $295 for ANA members and $340 for AANP or GAPNA members.

What Is the Passing Score for the FNP-BC?

The passing score for the FNP-BC exam is a scaled score of 350 on ANCC’s 100 to 500 range.^[3] Only the 150 scored questions count toward your result; the other 25 are unscored pretest items.

A modified Angoff process adjusts for slight differences in difficulty across exam forms, so the raw number correct needed to pass varies by version. A preliminary pass/fail result appears on screen immediately.

How Hard Is the FNP-BC? (Pass Rate)

The FNP-BC is a rigorous entry-level competency exam — ANCC reported a first-time pass rate of about 82% in 2025.^[1] The clinical content is broad, and the heavy Implementation weighting means many questions test professional role, ethics, legal and regulatory issues, and healthcare systems rather than pure clinical recall.

The takeaway: drill until you’re consistently scoring above target on full-length practice — especially Implementation and professional-role content — before you book.

What to Expect on Exam Day

Arrive at your Prometric test center at least 30 minutes early to check in — bring a valid, unexpired government-issued photo ID whose name matches your ANCC application.

^[1] You’ll store phones and personal items in a locker; no notes are allowed, but you’re given an erasable note board and an on-screen calculator.

A short tutorial precedes the exam, then you have 3.5 hours to answer 175 questions, including multiple-choice and alternate-format items like drag-and-drop and hotspot. If you test via remote proctoring, expect a similar room scan and ID check.

A preliminary pass/fail result appears on screen immediately, with the official report following shortly after. Having simulated the full timing with practice tests makes that clock feel routine.
