This free Med-Surg certification study guide walks through everything the medical-surgical nursing exam tests, organized into the same five practice domains the uses to build the exam.[1]
“Med-Surg certification” is the everyday name for the credential most med-surg nurses pursue — the CMSRN. This guide teaches to that blueprint. It is interactive, not a wall of text: every domain has worked clinical scenarios, high-yield drug, lab, and electrolyte tables, labeled diagrams, and built-in flashcards, so you learn by doing.
Because most clinical disease and pharmacology content is tested inside , we also include a dedicated body-systems module so the clinical depth is taught fully.
Read it domain by domain, then round out your prep with our Med-Surg practice test and flashcards. If you specifically want the dedicated CMSRN study system, we also maintain a full CMSRN hub — the same exam, the same standard, with its own practice, guide, and flashcards.

How the Med-Surg Exam Works
The Med-Surg (CMSRN) exam is a 150-item multiple-choice test — 125 scored items plus 25 unscored pretest items mixed in that you cannot identify — delivered in a single 3-hour session at a Pearson VUE test center or by OnVUE remote proctoring.[1] It is built to the level of an RN with roughly two years and 2,000 hours of med-surg practice.
Scoring is : you are measured against a fixed standard, not against other candidates. The passing standard — a scaled score of 95, about 71% of scored items correct — is set with subject-matter experts and psychometricians, and your pass/fail result appears immediately when you finish.[1] A detailed score report is posted to your certification portal.
Eligibility requires an active, unencumbered RN license plus 2,000 medical-surgical practice hours within the past 3 years. The credential is valid for 5 years and is renewed by contact hours or by re-examination.[1][3] Always confirm current fees and policies on msncb.org before you register.[2]
A life-threatening ABC problem is always first — an obstructed airway beats everything.
Oxygen, fluids, elimination, and safety come before comfort, esteem, or teaching.
Falls, infection, and medication safety outrank routine, non-urgent needs.
See the unstable, acute, actual, unexpected patient before the stable, chronic, 'risk-for,' expected one.
When data are incomplete, gather more — except in a true ABC emergency, where you intervene first.
Patient/Care Management
Patient/Care Management is the single largest domain at 32% of scored items — about 40 questions.[1] It covers how the med-surg nurse keeps patients safe across patient safety, infection prevention, medication management, pain management, surgical and procedural nursing, and nutrition and skin integrity. Most of the exam’s clinical disease and pharmacology content lives here.
Patient Safety
Safety is tested as a systems competency. The master rule is assess before you act — except in a true airway, breathing, or circulation emergency, where you intervene first and reassess after.
For falls, screen with a validated tool, apply universal precautions to everyone (bed low and locked, call light in reach, non-skid footwear, hourly rounding), and after a fall assess for injury first, then notify, document, and file an incident report.[12] For pressure injuries, screen with the , reposition at least every 2 hours, offload heels, and optimize nutrition.[16]
The exam loves safety-culture and improvement-method distinctions. A separates honest error from reckless behavior and encourages non-punitive reporting.
A (death or serious harm) triggers a , which is reactive (“why did this happen?”), while a Failure Mode and Effects Analysis is proactive (“what could go wrong?”).[12] For pressure injuries, remember that an injury’s depth cannot be judged until the slough or eschar is removed.[16]
Infection Prevention
apply to every patient, all the time — treat all blood and body fluids (except sweat), non-intact skin, and mucous membranes as potentially infectious. Hand hygiene is the single most effective measure; use soap and water when hands are visibly soiled and for C. difficile and norovirus, because alcohol does not kill spores.[9]
are added on top of standard precautions and are a frequent matrix-item task — match each patient to the right type.[8]
| Type | PPE & room | Examples |
|---|---|---|
| Contact | Gown + gloves; private room or cohort; dedicated equipment | MRSA, VRE, C. difficile, RSV, scabies |
| Droplet | Surgical mask within ~6 ft; private room | Influenza, pertussis, meningococcus, mumps |
| Airborne | N95 respirator; negative-pressure room, door closed | Tuberculosis, measles, varicella, disseminated zoster |
Medication Management
Verify the for every dose — right patient (two identifiers), drug, dose, route, and time, plus documentation, reason, response, education, and the right to refuse. Do three label checks, use barcode scanning, and never give a medication you did not prepare.[10]
carry a heightened risk of serious harm. The ISMP list includes anticoagulants (heparin, warfarin, DOACs), all insulins, opioids, neuromuscular blockers, chemotherapy, and concentrated electrolytes — especially potassium chloride, which is never given IV push. These require an independent double-check.[10]
For anticoagulants: heparin is monitored by aPTT (antidote protamine; watch platelets for ), and warfarin by INR 2.0–3.0 (antidote vitamin K; teach consistent, not zero, vitamin-K intake).[11]
| Agent | Lab monitored | Antidote / reversal |
|---|---|---|
| Heparin (unfractionated) | aPTT or anti-Xa; platelets for HIT | Protamine sulfate |
| Enoxaparin (LMWH) | Anti-Xa (not routine) | Protamine (partial) |
| Warfarin | INR/PT (target 2.0–3.0) | Vitamin K; urgent: 4-factor PCC |
| Dabigatran | None routine | Idarucizumab |
| Apixaban / rivaroxaban | None routine | Andexanet alfa (or PCC) |
Pain Management
Pain is whatever the patient says it is — believe self-report regardless of appearance. Match the assessment tool to the patient (a 0–10 numeric scale for verbal adults, FLACC for young or nonverbal children, PAINAD for nonverbal dementia, CPOT for the critically ill), and always reassess after intervention.
The evidence-based standard is — build on non-opioids and add opioids and adjuvants to maximize relief while minimizing the opioid dose, with a bowel regimen. The YMYL core is opioid safety: sedation precedes respiratory depression, so monitor sedation and respiratory rate; naloxone is titrated to respirations.[10]
Surgical & Procedural Nursing
Know the consent boundary: the provider explains the procedure and obtains ; the nurse witnesses the signature, confirms understanding, and verifies it is voluntary. The Universal Protocol prevents wrong-site surgery through verification, site marking, and a time-out before incision — anyone can stop the line.[12]
In the PACU, priorities are ABCs first (patent airway, gag reflex), then circulation and bleeding, then pain and nausea. For /, cover with sterile saline-soaked gauze, position low-Fowler’s with knees flexed, keep NPO, and notify the surgeon — never push the organs back in.
| Complication | Key recognition | First nursing action |
|---|---|---|
| Atelectasis | Diminished breath sounds, low fever POD 1–2 | Incentive spirometry, ambulate, splinted cough |
| DVT → PE | Unilateral calf swelling; PE = sudden dyspnea | Early ambulation/SCDs; for PE, oxygen + rapid response (do not massage) |
| Hemorrhage/shock | Rising HR, falling BP, saturated dressing | Apply pressure, reinforce dressing, notify surgeon, fluids/blood |
| Evisceration | Organs protrude through the wound | Sterile saline gauze, low-Fowler's knees flexed, NPO, call surgeon |
| Urinary retention | No void in ~6–8 h, distended bladder | Bladder scan first, then intermittent catheterization if needed |
Nutrition & Skin Integrity
Screen for malnutrition on admission and match the diet to the disease (sodium/fluid limits for heart failure, carbohydrate consistency for diabetes, protein/potassium/phosphorus limits for renal patients). Before oral intake in a stroke or neuro patient, screen for dysphagia and keep NPO until the swallow screen passes.
For enteral nutrition, an X-ray is the gold standard before first use of a blind tube, keep the head of the bed at 30–45°, and remember that auscultating an air “whoosh” does not verify placement.[18] Skin integrity is a nursing-sensitive outcome: stage pressure injuries with the system, and treat an injury as a wound whose depth is hidden by eschar.[16]
Checkpoint · Patient/Care Management
Question 1 of 9
A nurse reports an event in which a patient suffered unanticipated death unrelated to the natural course of illness. This type of event is best classified as which of the following?
Clinical Med-Surg by Body System
The Med-Surg exam tests clinical disease, pharmacology, and lab content chiefly within Patient/Care Management.[1] This module teaches that depth by body system so you can recognize cues and choose the safe action across the conditions a med-surg nurse manages every shift.
Cardiovascular
For acute coronary syndrome, obtain a 12-lead ECG within 10 minutes; troponin is the most specific marker, and a STEMI demands reperfusion (door-to-balloon PCI within 90 minutes). Give aspirin and nitroglycerin, but hold nitro if systolic BP is below 90 or in a right-ventricular/inferior MI.[15]
Distinguish left-sided heart failure (pulmonary congestion: crackles, orthopnea) from right-sided (systemic congestion: jugular venous distention, peripheral edema). The key teaching is daily weights — report a gain over 2–3 lb in a day or 5 lb in a week. Digoxin toxicity (worsened by hypokalemia) shows nausea, yellow-green halos, and bradycardia; hold for an apical pulse below 60.[15]
Respiratory & Acid-Base
Interpret arterial blood gases with — Respiratory Opposite, Metabolic Equal. For COPD, titrate oxygen to an SpO2 of about 88–92% to avoid suppressing the hypoxic drive, and teach pursed-lip breathing.[15]
For asthma, an ominous sign is a silent chest with diminishing wheezing — impending respiratory failure. Chest tubes are high-yield: keep the system below the chest, expect tidaling, and treat continuous bubbling as an air leak; if the tube is pulled out, cover the site with an occlusive dressing taped on three sides.
| Disorder | pH | PaCO2 | HCO3 | Common causes |
|---|---|---|---|---|
| Respiratory acidosis | Low | High | Normal/high | Hypoventilation, COPD, opioids |
| Respiratory alkalosis | High | Low | Normal/low | Hyperventilation, anxiety, PE, pain |
| Metabolic acidosis | Low | Normal/low | Low | DKA, lactic acidosis, diarrhea, renal failure |
| Metabolic alkalosis | High | Normal/high | High | Vomiting/NG suction, diuretics |
GI, Renal & Endocrine
For GI bleeding, assess hemodynamics first — tachycardia and hypotension precede a measurable hemoglobin drop. Pancreatitis shows epigastric pain radiating to the back with an elevated lipase; keep NPO to rest the pancreas.
In acute kidney injury and chronic kidney disease, hyperkalemia is the most life-threatening complication; protect the AV fistula (no BP or venipuncture in that arm; check the thrill and bruit).[18] For DKA, the management order is the exam favorite: IV fluids first, then a regular-insulin infusion, with potassium replacement (hold insulin if K is below 3.3), and add dextrose when glucose reaches about 200 mg/dL.[14]
| Insulin | Onset | Peak | Duration |
|---|---|---|---|
| Rapid (lispro, aspart) | ~15 min | ~1 h | 3–5 h |
| Short / Regular (only IV insulin) | ~30 min | 2–3 h | 5–8 h |
| Intermediate NPH (cloudy) | 1–2 h | 4–12 h | 12–18 h |
| Long-acting (glargine, detemir) | 1–2 h | No pronounced peak | Up to 24 h |
Neuro, MSK & Heme-Onc
For ischemic stroke, “time is brain” — get an immediate non-contrast CT to rule out a bleed before tPA. With increased intracranial pressure, the earliest sign is a change in level of consciousness, while is late and ominous; keep the head of the bed at 30° and midline.
After a fracture, do neurovascular checks; compartment syndrome’s early sign is pain out of proportion and pain on passive stretch — do not elevate above heart level. For heme-onc, any means stop the transfusion first, then keep the line open with normal saline through new tubing — an acute hemolytic (ABO-mismatch) reaction is the most dangerous.
Fluids, Electrolytes & Sepsis
Potassium (3.5–5.0 mEq/L) is the highest-yield safety topic. Hypokalemia causes flat T waves, U waves, weakness, and worsened digoxin toxicity — replace it diluted by pump, never IV push. Hyperkalemia causes peaked T waves progressing to a widened QRS; the treatment order is a three-step sequence.[18]
is tested through the Surviving Sepsis hour-1 bundle: measure lactate, draw blood cultures before antibiotics, give broad-spectrum antibiotics, give 30 mL/kg crystalloid for hypotension or lactate ≥ 4, and add vasopressors (norepinephrine first-line) to keep the mean arterial pressure at or above 65.[17]
IV calcium gluconate protects the myocardium from the peaked T waves and widening QRS — it does NOT lower potassium.
Regular insulin with dextrose (and often a nebulized beta-agonist such as albuterol) drives potassium intracellularly within minutes.
Loop diuretics, a potassium-binding resin, or dialysis — the only steps that actually lower total-body potassium.
| Hypokalemia (below 3.5) | Hyperkalemia (above 5.0) | |
|---|---|---|
| Causes | Diuretics, vomiting, NG suction | Renal failure, acidosis, tumor lysis, ACE inhibitors |
| ECG | Flat T waves, U waves | Peaked T waves → wide QRS → sine wave |
| Treatment | Dilute K by pump (never IV push); oral KCl with food | Calcium gluconate → insulin + dextrose/albuterol → remove (diuretics/binders/dialysis) |
Checkpoint · Clinical Med-Surg by Body System
Question 1 of 9
A nurse reviews a routine ECG on a patient with chronic kidney disease and notes tall, narrow, peaked ("tented") T waves as a new finding. Which electrolyte abnormality does this most likely reflect?
Holistic Patient Care
Holistic Patient Care is 15% of the exam — about 19 items.[1] It treats the patient as a whole person across patient-centered care, culture and spirituality, patient and family education, and advance directives and end-of-life care.
Patient-Centered Care
Patient-centered care makes the patient the locus of control: care respects and responds to individual preferences, needs, and values. The nurse uses active listening and sets mutual, patient-driven goals because they improve adherence and satisfaction. When a patient or family complains, the first action is to listen and acknowledge feelings, then apologize for the experience, act to resolve it, and escalate or document — never defend the staff first.[1]
Culture, Spirituality & Diversity
The goal is culturally and spiritually appropriate, equitable care. The single highest-yield rule is interpreter use: a qualified medical interpreter must be used for any patient with limited English proficiency or who is deaf — never family members, friends, children, or untrained staff, for accuracy, confidentiality, and legal reasons. Recognize implicit bias, assess each patient’s actual cultural, religious, and spiritual needs, and accommodate rituals and chaplain or spiritual-care requests within the plan of care.[1]
Patient & Family Education
Effective teaching is assessed, individualized, and evaluated. First assess readiness to learn — manage pain or anxiety before teaching — and address barriers (language, literacy, sensory deficits).
Use plain language at about a 5th–6th-grade level for low health literacy, and confirm understanding with — have the patient explain in their own words. A nodding “yes” to “do you understand?” is never adequate evidence of learning.
Advance Directives & End-of-Life Care
Honor and document and code status. A states which treatments a patient does or does not want; a names a proxy to decide once capacity is lost — and a competent patient’s current wishes always govern over either document.
A means resuscitation will not be attempted, not “do not treat”; comfort care continues. Distinguish (symptom relief at any stage, alongside curative care) from (comfort-only for a prognosis of about six months or less): all hospice care is palliative, but not all palliative care is hospice.
| Feature | Palliative care | Hospice care |
|---|---|---|
| Goal | Relieve symptoms, improve quality of life | Comfort and dignity at end of life |
| Timing | Any stage of serious illness | Prognosis generally 6 months or less |
| Curative treatment | Can run alongside curative care | Curative treatment stopped; comfort only |
| Eligibility | No prognosis requirement | Certification of terminal illness |
Checkpoint · Holistic Patient Care
Question 1 of 9
A nurse provides care that respects the patient's values, includes the patient in decisions, and tailors the plan to the patient's personal goals. Which principle of patient-centered care is the nurse demonstrating?
Elements of Interprofessional Care
Elements of Interprofessional Care is 17% of the exam — about 21 items.[1] It covers the nursing process and clinical judgment, collaboration, care coordination and transitions, and documentation and informatics.
Nursing Process & Clinical Judgment
The nursing process, , is the backbone of RN practice — a continuous cycle in which assessment is always first and evaluation closes the loop. The NCSBN model makes the thinking inside ADPIE explicit through six steps — recognize cues, analyze cues, prioritize hypotheses, generate solutions, take action, evaluate outcomes. When an item presents new data, recognize and analyze the cues before taking action, except in a true ABC or safety emergency.[6]
Interprofessional Collaboration
The RN is often the care coordinator who synthesizes input from medicine, pharmacy, PT/OT, respiratory therapy, dietitians, and social work. The high-yield teamwork framework is TeamSTEPPS (AHRQ): leadership, situation monitoring, mutual support, and communication. The most-tested behavior: a nurse whose safety concern is ignored applies the and escalates with CUS language (“I’m Concerned, I’m Uncomfortable, this is a Safety issue”) — never stays silent and never complies with an unsafe order.[13]
Care Coordination & Transitions
Transitions of care are high-risk for error and readmission. Discharge planning starts on admission.
The single most-tested transition-safety action is medication reconciliation— comparing the patient’s current medications to new orders at every transition to catch omissions, duplications, and interactions; it is a Joint Commission National Patient Safety Goal.[12] Screen for social determinants of health and refer to close the gaps that drive readmission.
Documentation & Informatics
Documentation must be accurate, timely, objective, and factual — “if it wasn’t documented, it wasn’t done.” Chart facts, not opinions, use only approved abbreviations, and never chart that an incident report was filed. During an EHR outage, initiate downtime procedures and document on paper, then enter the care when systems return.[12] With technology, assess the patient before the device when an alarm sounds, and remember that clinical decision support and telehealth support but never replace nursing judgment.
| Clinical-judgment step | What the nurse does | Maps to ADPIE |
|---|---|---|
| Recognize cues | Identify relevant data; separate expected from unexpected | Assessment |
| Analyze cues | Connect cues to the condition; interpret meaning | Assessment / Diagnosis |
| Prioritize hypotheses | Rank explanations by likelihood and urgency | Diagnosis |
| Generate solutions | Identify expected outcomes and interventions | Planning |
| Take action | Implement the highest-priority intervention | Implementation |
| Evaluate outcomes | Compare observed vs. expected; judge effectiveness | Evaluation |

Question 1 of 9
A patient with congestive heart failure is being discharged. Which of the following would be the most appropriate discharge instruction to reduce the risk of fluid overload?
Professional Concepts
Professional Concepts is 15% of the exam — about 19 items.[1] It covers ethics and advocacy, legal and regulatory standards, quality and safety management, and evidence-based practice and research.
Ethics & Advocacy
The is the profession’s nonnegotiable ethical standard, organized into nine provisions.[7] The principles are heavily tested: a competent patient’s (informed refusal) outweighs ; is “do no harm”; and disclosing an error to the patient is . — acting to protect the patient’s rights and best interests — is the thread that runs through end-of-life care, informed consent, and speaking up about unsafe care.[7]
Legal & Regulatory Standards
Scope of practice is defined by the state Nurse Practice Act and Board of Nursing — the nursing process and nursing judgment cannot be delegated. Know (protected health information may be used for treatment, payment, and operations on a minimum-necessary basis), EMTALA (screen and stabilize regardless of ability to pay), and the nurse’s status as a mandatory reporter of suspected abuse — report a reasonable suspicion to the proper authority even without proof.[7]
| Principle | Definition | Clinical example |
|---|---|---|
| Autonomy | Right to self-determination | Honoring a competent patient's informed refusal |
| Beneficence | Doing good / best interest | Providing pain relief |
| Nonmaleficence | 'Do no harm' | Reporting unsafe practice; avoiding undue risk |
| Justice | Fairness / equitable resources | Equal care regardless of ability to pay |
| Fidelity | Keeping promises; loyalty | Following through on what you told the patient |
| Veracity | Truthfulness | Honest disclosure of a diagnosis or an error |
Quality & Safety Management
(NDNQI) measure outcomes shaped by nursing care — falls, pressure injuries, CAUTI, CLABSI. Improvement methods include the Plan-Do-Study-Act (PDSA) cycle, Lean, and Six Sigma; remember that a looks back while a Failure Mode and Effects Analysis looks forward. In a , the nurse files a non-punitive incident or near-miss report so the system can be improved.[13]
Evidence-Based Practice & Research
integrates the best evidence, clinical expertise, and patient values; frame the question with and rank studies by the levels of evidence — a systematic review or meta-analysis of randomized controlled trials is the strongest. Before changing practice, appraise the evidence for quality and applicability to your patient population. The most-tested distinction: research generates new knowledge, EBP applies existing evidence, and quality improvement refines a local process; human-subjects research requires informed consent and IRB review.[7]
Checkpoint · Professional Concepts
Question 1 of 9
A medical-surgical nurse is participating in a research study. Which of the following actions is most critical to maintaining ethical standards in clinical research?
Nursing Teamwork & Collaboration
Nursing Teamwork and Collaboration is the second-largest domain at 21% of the exam — about 26 items.[1] It covers delegation and supervision, communication and escalation, and leadership, conflict, and professional development.
Delegation & Supervision
Delegation transfers the authority to perform a task while the RN retains accountability for the outcome.[5] Apply the — right task, circumstance, person, direction/communication, and supervision/evaluation.
The RN never delegates assessment, diagnosis, planning, evaluation, the initial teaching, triage, or the care of an unstable patient. may do ADLs, vital signs on stable patients, intake and output, and routine specimen collection — but a task like feeding a patient at risk for aspiration stays with the nurse because it needs ongoing judgment.[5]
Distinguish : assignment shifts tasks already within someone’s job role, while delegation transfers a task normally within the RN’s scope.
- ·Initial & ongoing assessment
- ·Nursing diagnosis & care plan
- ·Initial patient teaching
- ·Evaluate care effectiveness
- ·Unstable / acutely changing patients
- ·IV push meds, blood, triage
- ·Reinforce teaching the RN started
- ·Care for stable, predictable patients
- ·Most routine PO / IM / SubQ meds (state-dependent)
- ·Dressing changes & focused data
- ·Not the initial assessment or care plan
- ·Not the unstable patient (most states)
- ·ADLs: bathe, feed, ambulate, hygiene
- ·Vital signs on STABLE patients
- ·Intake & output, daily weights
- ·Routine specimen collection
- ·Transfers & positioning
- ·Never anything requiring judgment
Communication & Escalation
Communication failures are the most common root cause of sentinel events, so the exam tests structured, escalating communication. Use for nurse-to-provider escalation and for verbal orders and critical values.
When a safety concern is unresolved, follow the — keep escalating up until the patient is safe. For deterioration, activate the rapid response team before arrest.[13]
Leadership, Conflict & Development
Choose transformational leadership for change and engagement (autocratic only in a true emergency), and resolve conflict by addressing it directly and collaboratively, focused on the shared goal of patient safety.
Three developmental roles are routinely confused: a guides long-term career growth, a coach builds a specific skill, and a guides the clinical orientation of a new nurse. A daily safety huddle establishes a shared mental model and proactively surfaces risks. Team nursing is the most common med-surg care-delivery model.[13]
| Role | Can do | Cannot do (stays with RN) |
|---|---|---|
| RN | Full nursing process, initial teaching, unstable patients, IV push, blood, triage | Cannot exceed the state Nurse Practice Act |
| LPN/LVN | Reinforce teaching, stable-patient care, routine meds (state-dependent), dressing changes | Initial assessment, care plan, initial teaching, evaluation, unstable patients |
| UAP | ADLs, vital signs on stable patients, intake & output, routine specimens, transfers | Anything requiring assessment, teaching, evaluation, or judgment |
- 1
Step 1
Is the task routine, standardized, and predictable (the right task)? If it needs nursing judgment, the RN keeps it.
- 2
Step 2
Is the patient stable (the right circumstance)? Unstable or rapidly changing patients stay with the RN.
- 3
Step 3
Is the delegatee competent and within scope for this task and patient (the right person)?
- 4
Step 4
Give clear direction and communication — what to do, limits, and what/when to report back.
- 5
Step 5
Supervise and evaluate: monitor, stay available, intervene, and judge the outcome — accountability stays with you.

How to Use This Study Guide
Work through the guide one domain at a time. After each domain, check it off in the contents to raise your exam-readiness score, then drill the same content in our free practice test and flashcards — active recall and timed practice are what move knowledge into exam-day performance.
- Weight your time by the blueprint. Patient/Care Management (32%) and Teamwork & Collaboration (21%) are more than half the exam — start there.
- Master delegation and prioritization. A large share of items hinge on the five rights of delegation, RN-vs-LPN-vs-UAP scope, and “who do you see first.”
- Memorize the high-frequency safety facts. Isolation precautions, the rights of medication administration, electrolyte signs, and antidotes appear again and again.
- Study the clinical module deeply. The body-systems content is tested within Patient/Care Management, so the disease, drug, and lab depth is worth real time.
- Want the dedicated CMSRN set? This is the same exam — our CMSRN hub has its own practice, guide, and flashcards if you prefer to study under that name.
Common questions med-surg nurses search and get asked — each answered briefly and backed by an official source (NCSBN, CDC, ISMP, FDA, ANA, AHRQ, ADA, NHLBI, or the Surviving Sepsis Campaign). Tap any card to test yourself.

- evidence-based practice
- Integrating the best available evidence with clinical expertise and patient values to guide care decisions.
- PICOT
- Population, Intervention, Comparison, Outcome, and Time — the framework for an answerable evidence-based-practice question.
- nursing-sensitive indicators

- five rights of delegation
- NCSBN's framework for safe delegation: right task, right circumstance, right person, right direction/communication, and right supervision/evaluation.
- UAP
- Unlicensed assistive personnel — a nursing assistant or technician who may perform ADLs, vital signs on stable patients, and routine tasks, but never assessment, teaching, or judgment.

- mentor
- An experienced nurse who guides another's longer-term professional and career development.
Med-Surg Study Guide FAQ
The Med-Surg certification recognizes an RN's expertise in medical-surgical nursing. The most widely held med-surg credential is the CMSRN (Certified Medical-Surgical Registered Nurse), awarded by the Medical-Surgical Nursing Certification Board (MSNCB), the credentialing arm of the Academy of Medical-Surgical Nurses (AMSN).
The CMSRN exam has 150 multiple-choice questions — 125 scored items plus 25 unscored pretest items that look identical. You have 3 hours (180 minutes) at a Pearson VUE test center or by OnVUE remote proctoring. Answer every question, since you cannot tell the pretest items apart.
The CMSRN is criterion-referenced and reported as a scaled score; the passing standard is a scaled score of 95, which corresponds to roughly 71% of the 125 scored items answered correctly. The result is pass/fail and is shown immediately at the end of the exam.
Five domains of med-surg nursing practice: Patient/Care Management (32%), Nursing Teamwork and Collaboration (21%), Elements of Interprofessional Care (17%), Holistic Patient Care (15%), and Professional Concepts (15%). Most clinical disease, pharmacology, and lab content is tested within Patient/Care Management.
You need a current, active, unencumbered RN license (U.S., its territories, or Canada) plus 2,000 hours of medical-surgical nursing practice within the past 3 years. The exam is written to the level of an RN with about two years of med-surg experience.
They are the same thing for most nurses — "Med-Surg certification" is the everyday name for the CMSRN credential. This guide teaches the CMSRN blueprint. If you want the dedicated CMSRN study system, use our CMSRN practice test, study guide, and flashcards in the nursing section.
The CMSRN credential is valid for 5 years. You recertify by completing continuing-education and professional-development requirements (with med-surg practice hours during the period) or by retaking the exam, while keeping your RN license unencumbered.
Work through it by domain, weighting your time toward Patient/Care Management (32%) and Nursing Teamwork and Collaboration (21%). Study the body-systems module for clinical depth, then drill each area with our free practice test and flashcards, focusing on delegation, precautions, medications, and electrolytes.
Yes — the full guide, the glossary, the concept questions, the practice test, and the flashcards are 100% free with no account required.
