Lisinopril (an ACE inhibitor), Amlodipine (a calcium channel blocker), and Furosemide 'a loop diuretic' are used to manage hypertension and heart failure but do not specifically prevent stroke in atrial fibrillation like Warfarin does.
- Which medication is considered a first-line treatment for heart failure with reduced ejection fraction (HFrEF)?
- Digoxin
- Furosemide
- Enalapril
- Atenolol
Correct answer: Enalapril
Correct answer: Enalapril. Explanation: Enalapril, an ACE inhibitor, is considered a first-line treatment for heart failure with reduced ejection fraction (HFrEF) due to its proven benefit in reducing mortality and morbidity. While Digoxin and Furosemide are used in heart failure management, they are not considered first-line treatments. Atenolol, a beta-blocker, may be used in heart failure but is not as commonly indicated as ACE inhibitors for HFrEF.
- What is the mechanism of action of Allopurinol in the treatment of gout?
- Increases uric acid excretion
- Inhibits xanthine oxidase
- Blocks tubular reabsorption of uric acid
- Inhibits cyclooxygenase
Correct answer: Inhibits xanthine oxidase
Correct answer: Inhibits xanthine oxidase. Explanation: Allopurinol works by inhibiting xanthine oxidase, an enzyme involved in the conversion of hypoxanthine to xanthine to uric acid, thereby reducing uric acid production. This mechanism differs from increasing uric acid excretion or blocking its reabsorption, which are actions of other types of gout medications. It also does not inhibit cyclooxygenase, which is the action of NSAIDs.

- Biguanide
Correct answer: Biguanide
Metformin is a biguanide. It lowers blood glucose primarily by decreasing hepatic glucose production and improving insulin sensitivity, and it does not typically cause hypoglycemia on its own. Sulfonylureas (such as glipizide) stimulate insulin release, thiazolidinediones (such as pioglitazone) improve insulin sensitivity through a different mechanism, and DPP-4 inhibitors (such as sitagliptin) increase incretin levels.
- Lisinopril is widely prescribed for hypertension and heart failure. Which drug class does it belong to?
- Angiotensin receptor blocker
- Calcium channel blocker
- ACE inhibitor
- Beta blocker
Correct answer: ACE inhibitor
Lisinopril is an ACE inhibitor (angiotensin-converting enzyme inhibitor). The -pril suffix is the recognized stem for ACE inhibitors, which lower blood pressure by blocking the conversion of angiotensin I to angiotensin II. Angiotensin receptor blockers carry the -sartan stem, calcium channel blockers such as amlodipine end in -dipine, and beta blockers end in -olol.
- Generic drug names often share a common suffix, or stem, that signals the drug class. Medications ending in the suffix '-statin' belong to which class?
- Antiplatelet agents
- HMG-CoA reductase inhibitors
- Loop diuretics
- Proton pump inhibitors
Correct answer: HMG-CoA reductase inhibitors
The -statin suffix identifies HMG-CoA reductase inhibitors, the cholesterol-lowering 'statins' such as atorvastatin, simvastatin, and rosuvastatin. They block the enzyme HMG-CoA reductase to reduce LDL cholesterol synthesis. Proton pump inhibitors use the -prazole stem, while loop diuretics and antiplatelet agents do not share the -statin stem.
- Drugs such as metoprolol, atenolol, and carvedilol are used for cardiovascular conditions. The shared suffix '-olol' identifies which drug class?
- ACE inhibitors
- Calcium channel blockers
- Alpha blockers
- Beta-adrenergic blockers
Correct answer: Beta-adrenergic blockers
The -olol suffix identifies beta-adrenergic blockers (beta blockers). Metoprolol, atenolol, propranolol, and others share this stem and reduce heart rate and blood pressure by blocking beta receptors. Calcium channel blockers end in -dipine, alpha blockers such as doxazosin end in -zosin, and ACE inhibitors end in -pril.
- A pharmacy technician is explaining the difference between brand name and generic name drugs to a trainee. Which statement accurately describes this distinction?
- The generic name changes with each manufacturer while the brand name stays the same across companies
- The generic name is always longer and assigned by the marketing company
- The brand name is the trademarked proprietary name and the generic name is the nonproprietary chemical name shared by all manufacturers
- Brand and generic versions must contain different active ingredients
Correct answer: The brand name is the trademarked proprietary name and the generic name is the nonproprietary chemical name shared by all manufacturers
The brand name is the trademarked, proprietary name owned by one company, while the generic name is the single nonproprietary name shared by all manufacturers of that active ingredient. For example, atorvastatin (generic) is sold as Lipitor (brand). Generic and brand versions contain the same active ingredient, and the generic name does not vary by manufacturer.
- A patient is prescribed insulin lispro to take with meals. Compared with insulin glargine, how does the onset and duration of rapid-acting insulin lispro differ?
- Lispro has a faster onset (about 15 minutes) and shorter duration (about 3 to 5 hours) than glargine
- Lispro has no peak while glargine peaks sharply at 1 hour
- Lispro has a slower onset and longer duration than glargine
- Lispro and glargine have identical onset and duration
Correct answer: Lispro has a faster onset (about 15 minutes) and shorter duration (about 3 to 5 hours) than glargine
Rapid-acting insulin lispro has a fast onset of about 15 minutes and a short duration of roughly 3 to 5 hours, so it is dosed with meals to cover post-meal glucose spikes. Insulin glargine is a long-acting basal insulin with an onset of 1 to 2 hours, no pronounced peak, and a duration of about 24 hours, making it the opposite profile.
- A pharmacist asks the technician to flag a narrow therapeutic index (NTI) drug during refill review. What best defines a narrow therapeutic index drug?
- A drug that has no known drug interactions
- A drug that requires refrigeration during storage
- A drug that is only available as a brand name product
- A drug for which small differences in dose or blood concentration can cause therapeutic failure or serious toxicity
Correct answer: A drug for which small differences in dose or blood concentration can cause therapeutic failure or serious toxicity
A narrow therapeutic index drug is one for which small differences in dose or blood concentration can lead to therapeutic failure or serious, sometimes life-threatening, toxicity. Examples include warfarin, digoxin, lithium, levothyroxine, and phenytoin, all of which require careful monitoring. The definition has nothing to do with brand-only availability, refrigeration, or the absence of interactions.
- Which of the following medications is classified as a narrow therapeutic index drug that typically requires routine blood-level or lab monitoring?
- Warfarin
- Acetaminophen
- Docusate sodium
- Loratadine
Correct answer: Warfarin
Warfarin is a narrow therapeutic index anticoagulant that requires routine INR monitoring because small dose changes can cause bleeding (if too high) or clotting (if too low). Acetaminophen, loratadine, and docusate sodium have wide safety margins and do not require routine therapeutic blood-level monitoring.
- A study resource lists the top 200 drugs by brand and generic name. Which brand-and-generic pairing is correct?
- Zofran = granisetron
- Zoloft = sertraline
- Nexium = omeprazole
- Norvasc = metoprolol
Correct answer: Zoloft = sertraline
Zoloft is the brand name for sertraline, an SSRI antidepressant. Nexium is esomeprazole (omeprazole is Prilosec), and Norvasc is amlodipine (not metoprolol). Zofran is ondansetron, not granisetron, so that pairing is also incorrect.
- A patient brings in prescriptions for warfarin and aspirin from two different prescribers. Why is this combination a common drug interaction concern the technician should flag?
- Aspirin reverses the anticoagulant action of warfarin
- The combination causes dangerously high blood pressure
- The two drugs cancel out each other's effect entirely
- Both increase bleeding risk, so taking them together raises the chance of hemorrhage
Correct answer: Both increase bleeding risk, so taking them together raises the chance of hemorrhage
Combining warfarin and aspirin increases bleeding risk because both interfere with normal clotting (warfarin inhibits clotting factor synthesis and aspirin inhibits platelet aggregation). Together they raise the chance of serious hemorrhage, which is why the interaction should be flagged for the pharmacist. Aspirin does not reverse warfarin, and the concern is bleeding, not hypertension.
- A technician is reviewing potential interactions. Which combination represents a clinically significant interaction that should be flagged because it can dangerously increase serum potassium?
- Amoxicillin and cephalexin
- Acetaminophen and ibuprofen
- Loratadine and pseudoephedrine
- Lisinopril and potassium chloride supplement
Correct answer: Lisinopril and potassium chloride supplement
Lisinopril taken with a potassium chloride supplement can cause hyperkalemia because ACE inhibitors reduce potassium excretion, and adding potassium compounds the effect. This combination should be flagged for the pharmacist. The other pairings do not pose a significant hyperkalemia risk.
- Under the federal Controlled Substances Act, hydrocodone-containing combination products are classified in which DEA schedule following their 2014 rescheduling?
- Schedule II
- Schedule V
- Schedule IV
- Schedule III
Correct answer: Schedule II
Hydrocodone combination products are Schedule II (CII) controlled substances. The DEA moved hydrocodone combination products from Schedule III to Schedule II effective October 6, 2014, due to their high abuse and dependence potential. Schedule III, IV, and V substances have progressively lower abuse potential.
- Pregabalin is dispensed at the pharmacy under federal controlled-substance rules. Which DEA schedule applies to pregabalin?
- Schedule IV
- Schedule V
- Schedule III
- Schedule II
Correct answer: Schedule V
Pregabalin (Lyrica) is a Schedule V (CV) controlled substance, the schedule reserved for drugs with the lowest abuse potential among controlled substances. It is not Schedule II, III, or IV. Cough preparations with limited codeine amounts are other examples of Schedule V products.
- During order processing, a technician encounters two products that are 'look-alike, sound-alike' (LASA). Which pairing is a recognized LASA pair that increases the risk of a dispensing error?
- Amoxicillin and acetaminophen
- Hydroxyzine and hydralazine
- Loratadine and cetirizine
- Ibuprofen and naproxen
Correct answer: Hydroxyzine and hydralazine
Hydroxyzine and hydralazine are a recognized look-alike, sound-alike (LASA) pair: hydroxyzine is an antihistamine while hydralazine is an antihypertensive, yet their similar spelling and pronunciation invite mix-ups. The Institute for Safe Medication Practices recommends tall man lettering (hydrOXYzine vs. hydrALAZINE) to reduce this error. The other pairs are not classic LASA confusions.
- To reduce medication errors, ISMP recommends using 'tall man lettering' for certain drug names. What is the purpose of tall man lettering?
- To show the expiration date in bold
- To mark a drug that must be refrigerated
- To indicate a drug is a controlled substance
- To use mixed-case letters that highlight the differences between look-alike drug names
Correct answer: To use mixed-case letters that highlight the differences between look-alike drug names
Tall man lettering uses uppercase letters within a drug name to emphasize the parts that differ between look-alike, sound-alike products, such as predniSONE versus prednisoLONE. This error-prevention strategy helps staff visually distinguish confusable names. It is not used to flag controlled status, expiration dates, or storage requirements.
- A prescription reads 'instill 1 gtt OD QID.' Which interpretation of the sig codes is correct?
- Instill 1 tablet by mouth four times daily
- Instill 1 drop in the right eye four times daily
- Instill 1 drop in both eyes once daily
- Instill 1 drop in the left eye four times daily
Correct answer: Instill 1 drop in the right eye four times daily
Instill 1 drop in the right eye four times daily is correct: 'gtt' means drop, 'OD' means right eye (oculus dexter), and 'QID' means four times daily. 'OS' would be the left eye and 'OU' both eyes, while 'gtt' refers to a drop rather than a tablet.
- An insulin glargine vial contains 10 mL of U-100 insulin. If a patient injects 25 units once daily, how many days will one vial last (ignoring waste)?
- 30 days
- 50 days
- 40 days
- 20 days
Correct answer: 40 days
40 days is correct. U-100 means 100 units per mL, so a 10 mL vial contains 1,000 units. Dividing 1,000 units by 25 units per day gives 40 days. The other options do not match the recomputed total.
- An ophthalmic solution is dispensed in a 30 mL bottle. The patient instills 2 drops in each eye twice daily. If there are 20 drops per mL, approximately how many days will the bottle last?
- 60 days
- 90 days
- 100 days
- 75 days
Correct answer: 75 days
75 days is correct. Two drops in each of two eyes equals 4 drops per dose, and twice daily equals 8 drops per day. A 30 mL bottle at 20 drops per mL holds 600 drops; 600 divided by 8 equals 75 days.
- A child weighing 40 kg is prescribed an antibiotic at 25 mg/kg/day divided into two equal doses every 12 hours. How many milligrams are in each dose?
- 1000 mg
- 400 mg
- 250 mg
- 500 mg
Correct answer: 500 mg
500 mg per dose is correct. The daily dose is 25 mg/kg×40 kg=1,000 mg per day. Divided into two equal doses, each dose is 1,000÷2=500 mg. The 1,000 mg figure is the full daily amount, not a single dose.
- An order requires 1,000 mL of IV fluid to infuse over 8 hours using tubing with a drop factor of 15 gtt/mL. What is the flow rate in drops per minute (rounded to the nearest whole drop)?
- 21 gtt/min
- 42 gtt/min
- 31 gtt/min
- 60 gtt/min
Correct answer: 31 gtt/min
31 gtt/min is correct. The rate is 1,000 mL÷8 hr=125 mL/hr. Multiplying 125 mL/hr×15 gtt/mL=1,875 gtt/hr; dividing by 60 minutes yields 31.25, which rounds to 31 gtt/min.
- A topical preparation contains 2.5 g of active ingredient in 50 mL of solution. What is the percentage strength (% w/v) of this solution?
Correct answer: 5%
5% w/v is correct. Percent weight-in-volume equals grams of drug per 100 mL. With 2.5 g in 50 mL, the proportion is 502.5=0.05, or 5 g per 100 mL =5%. The other values do not match the recomputed ratio.
- A medication's package insert directs that the product be 'protected from light' and stored at controlled room temperature. Which storage practice best follows these instructions?
- Refrigerate at 2 to 8 C in a clear bag
- Keep in its original light-resistant container at approximately 20 to 25 C
- Store in the freezer at -20 C
- Store on an open shelf in direct sunlight
Correct answer: Keep in its original light-resistant container at approximately 20 to 25 C
Keeping the product in its original light-resistant container at approximately 20 to 25 C correctly follows 'protect from light' and controlled room temperature instructions. Controlled room temperature is defined as about 20 to 25 C. Freezing, refrigerating in a clear bag, or leaving the product in direct sunlight would violate the storage and light-protection requirements.
- Under the Drug Supply Chain Security Act (DSCSA), pharmacy technicians help verify product as it moves through the supply chain. What is the technician's role when a suspect or illegitimate product is identified?
- Immediately dispense the product to avoid waste
- Relabel the product with a new lot number
- Quarantine the suspect product and notify the pharmacist so it can be investigated and reported
- Return it directly to the patient
Correct answer: Quarantine the suspect product and notify the pharmacist so it can be investigated and reported
Quarantining the suspect product and notifying the pharmacist for investigation and reporting is the correct DSCSA response. Suspect or illegitimate product must be segregated from dispensable stock and not used until cleared, with the proper notifications made to authorities and trading partners. Dispensing, relabeling, or returning it to a patient would be unsafe and noncompliant.
- A patient requests the generic name for Coumadin, an anticoagulant. Which generic name should the technician provide?
- Heparin
- Warfarin
- Enoxaparin
- Rivaroxaban
Correct answer: Warfarin
Warfarin is the generic name for Coumadin, an oral vitamin K antagonist anticoagulant. Heparin and enoxaparin are injectable anticoagulants, and rivaroxaban (Xarelto) is a direct oral factor Xa inhibitor, so none of those is the generic for Coumadin.
- A patient picks up Glucophage for type 2 diabetes and asks what the generic name is. What should the technician say?
- Glipizide
- Metformin
- Sitagliptin
- Pioglitazone
Correct answer: Metformin
Metformin is the generic name for Glucophage, a biguanide used as first-line therapy for type 2 diabetes. Glipizide is a sulfonylurea (Glucotrol), pioglitazone is a thiazolidinedione (Actos), and sitagliptin is a DPP-4 inhibitor (Januvia), all of which are different brand and generic pairings.
- Which brand-name product corresponds to the generic drug escitalopram, an antidepressant?
Correct answer: Lexapro
Lexapro is the brand name for escitalopram, an SSRI antidepressant. Celexa is citalopram, Prozac is fluoxetine, and Paxil is paroxetine, so those brands correspond to different SSRIs.
- Albuterol is dispensed as a metered-dose inhaler for asthma. To which drug class does albuterol belong?
- Long-acting muscarinic antagonist
- Short-acting beta-2 agonist
- Leukotriene receptor antagonist
- Inhaled corticosteroid
Correct answer: Short-acting beta-2 agonist
Albuterol is a short-acting beta-2 agonist (SABA) that relaxes airway smooth muscle for quick relief of bronchospasm, which is why it is often called a rescue inhaler. Inhaled corticosteroids such as fluticasone control inflammation, long-acting muscarinic antagonists such as tiotropium are maintenance bronchodilators, and montelukast is a leukotriene receptor antagonist.
- Omeprazole is used to reduce stomach acid in conditions such as GERD. What is its mechanism of action?
- Neutralizes existing stomach acid chemically
- Irreversibly inhibits the H+/K+ ATPase proton pump
- Coats and protects the stomach lining
- Blocks histamine H2 receptors on parietal cells
Correct answer: Irreversibly inhibits the H+/K+ ATPase proton pump
Omeprazole is a proton pump inhibitor that irreversibly blocks the H+/K+ ATPase (proton pump) in gastric parietal cells, sharply reducing acid secretion. Antacids chemically neutralize acid, H2 blockers such as ranitidine block histamine H2 receptors, and sucralfate coats the stomach lining, so those describe different acid-related drugs.
- Amlodipine is widely prescribed for hypertension. Which drug class does amlodipine belong to?
- Angiotensin receptor blocker
- Dihydropyridine calcium channel blocker
- Thiazide diuretic
- ACE inhibitor
Correct answer: Dihydropyridine calcium channel blocker
Amlodipine is a dihydropyridine calcium channel blocker, identified by the -dipine stem, and it lowers blood pressure by relaxing vascular smooth muscle. ACE inhibitors carry the -pril stem, ARBs carry the -sartan stem, and thiazide diuretics such as hydrochlorothiazide work on the kidney rather than calcium channels.
- A patient is counseled that omeprazole should be taken before a meal. Drugs whose generic names end in '-prazole' belong to which class?
- Antacids
- Proton pump inhibitors
- Prokinetic agents
- H2 receptor antagonists
Correct answer: Proton pump inhibitors
The -prazole stem identifies proton pump inhibitors such as omeprazole, esomeprazole, pantoprazole, and lansoprazole, which suppress gastric acid by blocking the proton pump. H2 antagonists end in -tidine, while antacids and prokinetic agents do not share the -prazole stem.
- A patient taking metronidazole asks whether they can have a glass of wine with dinner. What is the most appropriate counseling point?
- Alcohol only matters if taken with food
- Alcohol should be avoided during therapy and for about 3 days after, because it can cause a disulfiram-like reaction
- Alcohol increases the antibiotic's effectiveness
- Alcohol may be consumed freely with this medication
Correct answer: Alcohol should be avoided during therapy and for about 3 days after, because it can cause a disulfiram-like reaction
Patients taking metronidazole should avoid alcohol during therapy and for about 3 days after finishing, because the combination can trigger a disulfiram-like reaction with flushing, nausea, vomiting, and cramping. This counseling also extends to alcohol-containing products such as some mouthwashes and liquid medications. Alcohol does not enhance the drug's effectiveness.
- A patient on simvastatin should be cautioned about consuming large amounts of which food, due to a clinically important drug-food interaction?
- Bananas
- Cranberry juice
- Grapefruit juice
- Dairy products
Correct answer: Grapefruit juice
Grapefruit juice inhibits the CYP3A4 enzyme that metabolizes simvastatin, raising drug levels and increasing the risk of muscle toxicity such as myopathy and rhabdomyolysis. Cranberry juice is more associated with warfarin concerns, bananas matter for potassium-affecting drugs, and dairy is a concern with certain antibiotics rather than statins.
- A patient taking warfarin asks about diet. Which dietary component should they keep consistent because it can reduce warfarin's anticoagulant effect?
- Iron
- Calcium
- Vitamin C
- Vitamin K
Correct answer: Vitamin K
Vitamin K counteracts warfarin, so large or inconsistent intake of vitamin K-rich foods such as leafy green vegetables can reduce its anticoagulant effect and lower the INR. Patients are advised to keep their vitamin K intake consistent rather than eliminate it. Vitamin C, calcium, and iron do not have this direct antagonistic relationship with warfarin.
- Levothyroxine has specific administration instructions to maximize absorption. How should it typically be taken?
- Immediately after taking calcium or iron supplements
- On an empty stomach, about 30 to 60 minutes before breakfast
- With a high-fat meal at bedtime
- Crushed and mixed into milk
Correct answer: On an empty stomach, about 30 to 60 minutes before breakfast
Levothyroxine is best taken on an empty stomach about 30 to 60 minutes before breakfast to ensure consistent absorption. Calcium, iron, and certain foods can bind levothyroxine and reduce absorption, so they should be separated by several hours. Taking it with a high-fat meal or with milk interferes with absorption.
- A patient receives lisinopril and reports a persistent dry cough that started after beginning the drug. This is a recognized side effect of which drug class?
- ACE inhibitors
- Beta blockers
- Calcium channel blockers
- Loop diuretics
Correct answer: ACE inhibitors
A persistent dry cough is a well-known side effect of ACE inhibitors such as lisinopril, caused by the buildup of bradykinin. Patients who cannot tolerate the cough are often switched to an angiotensin receptor blocker, which does not typically cause it. Beta blockers, calcium channel blockers, and loop diuretics are not characteristically associated with this dry cough.
- Spironolactone is used for heart failure and resistant hypertension. To which drug class does it belong?
- Potassium-sparing diuretic
- Carbonic anhydrase inhibitor
- Loop diuretic
- Thiazide diuretic
Correct answer: Potassium-sparing diuretic
Spironolactone is a potassium-sparing diuretic that works by blocking the aldosterone receptor, which causes the body to retain potassium while excreting sodium and water. Because it raises potassium, combining it with ACE inhibitors or potassium supplements increases the risk of hyperkalemia. Loop and thiazide diuretics tend to lower potassium, and carbonic anhydrase inhibitors act by a different mechanism.
- A patient is prescribed ciprofloxacin and also takes calcium carbonate antacids. Why should the technician flag this combination?
- The antacid increases the risk of ciprofloxacin toxicity
- The combination causes dangerously low blood pressure
- The antacid converts ciprofloxacin into an inactive controlled substance
- Calcium can bind the fluoroquinolone and reduce its absorption and effectiveness
Correct answer: Calcium can bind the fluoroquinolone and reduce its absorption and effectiveness
Calcium and other polyvalent cations such as magnesium, aluminum, and iron chelate (bind) fluoroquinolones like ciprofloxacin, reducing their absorption and antibiotic effectiveness. Patients should separate the antacid and the antibiotic by several hours. The interaction reduces efficacy rather than causing toxicity or hypotension.
- A patient asks why their amoxicillin oral suspension must be kept in the refrigerator after the pharmacy mixes it. What is the best explanation?
- Once reconstituted, the suspension is more stable when refrigerated and typically must be discarded after about 14 days
- Refrigeration is required by law for all antibiotics
- Cold temperatures increase the antibiotic potency
- It prevents the medication from becoming a controlled substance
Correct answer: Once reconstituted, the suspension is more stable when refrigerated and typically must be discarded after about 14 days
Reconstituted amoxicillin suspension is more chemically stable when refrigerated and is usually discarded after about 14 days, since the active drug degrades once water is added. Not all antibiotics require refrigeration, and cold storage maintains rather than increases potency. Storage requirements are unrelated to controlled-substance status.
- Insulin that has not yet been opened should be stored under which condition before its first use?
- On a sunny windowsill at room temperature
- Refrigerated at about 2 to 8 degrees Celsius
- In a hot water bath to keep it warm
- In the freezer until needed
Correct answer: Refrigerated at about 2 to 8 degrees Celsius
Unopened insulin should be refrigerated at about 2 to 8 degrees Celsius (36 to 46 degrees Fahrenheit) to remain stable until its expiration date. Insulin must never be frozen, as freezing destroys it, and it should be protected from direct sunlight and heat. Once in use, many insulins can be kept at room temperature for about 28 days.
- Sublingual nitroglycerin tablets used for angina have special storage needs. How should they be stored to preserve potency?
- Loose in a pocket for quick access
- In a weekly pill organizer for convenience
- In their original amber glass container, tightly closed, away from light, heat, and moisture
- In the refrigerator inside a clear plastic bag
Correct answer: In their original amber glass container, tightly closed, away from light, heat, and moisture
Sublingual nitroglycerin tablets should be kept in their original amber glass container with the cap tightly closed, protected from light, heat, and moisture, because the drug is volatile and degrades easily. Transferring them to a pill organizer or plastic bag, or exposing them to body heat in a pocket, can cause loss of potency. They are stored at controlled room temperature, not refrigerated.
- Sertraline is commonly dispensed for depression and anxiety. Which drug class does sertraline belong to?
- Selective serotonin reuptake inhibitor
- Tricyclic antidepressant
- Monoamine oxidase inhibitor
- Benzodiazepine
Correct answer: Selective serotonin reuptake inhibitor
Sertraline (Zoloft) is a selective serotonin reuptake inhibitor (SSRI) that increases serotonin levels by blocking its reuptake. Tricyclic antidepressants such as amitriptyline and MAO inhibitors such as phenelzine are older antidepressant classes, and benzodiazepines such as lorazepam are anti-anxiety sedatives rather than antidepressants.
- A patient on an SSRI is started on tramadol for pain. Why might the technician flag this combination for the pharmacist?
- Together they increase the risk of serotonin syndrome
- The two drugs cancel each other out
- Tramadol blocks the absorption of the SSRI
- The combination causes severe constipation only
Correct answer: Together they increase the risk of serotonin syndrome
Combining an SSRI with tramadol increases the risk of serotonin syndrome because both raise serotonin activity, which can cause agitation, rapid heart rate, high temperature, and muscle rigidity. This interaction should be flagged for the pharmacist to evaluate. The drugs do not cancel each other out, and tramadol does not block SSRI absorption.
- Montelukast is prescribed for asthma and allergic rhinitis. What is its mechanism of action?
- It is a leukotriene receptor antagonist that blocks leukotriene-mediated bronchoconstriction
- It is a beta-2 agonist that relaxes airway smooth muscle
- It is an inhaled corticosteroid that reduces airway inflammation directly
- It is an anticholinergic that dries secretions
Correct answer: It is a leukotriene receptor antagonist that blocks leukotriene-mediated bronchoconstriction
Montelukast (Singulair) is a leukotriene receptor antagonist taken orally to block leukotrienes, which contribute to bronchoconstriction and inflammation in asthma and allergic rhinitis. It is not an inhaled corticosteroid, a beta-2 agonist, or an anticholinergic, which work through different mechanisms.
- A patient asks the technician for the generic name of Plavix, an antiplatelet drug used after stent placement. What is the correct generic name?
- Clopidogrel
- Prasugrel
- Dipyridamole
- Ticagrelor
Correct answer: Clopidogrel
Clopidogrel is the generic name for Plavix, an antiplatelet agent that inhibits the P2Y12 receptor to prevent clot formation. Ticagrelor (Brilinta), prasugrel (Effient), and dipyridamole are other antiplatelet drugs sold under different names, so they are not the generic for Plavix.
- Hydrochlorothiazide is frequently prescribed for hypertension. A common metabolic side effect of this thiazide diuretic is which of the following?
- Hyperkalemia
- Hypokalemia
- Vitamin K deficiency
- Hyperglycemia is impossible with this drug
Correct answer: Hypokalemia
Hydrochlorothiazide, a thiazide diuretic, commonly causes hypokalemia (low potassium) because it increases potassium loss in the urine. This contrasts with potassium-sparing diuretics such as spironolactone, which can raise potassium. Thiazides can also raise blood glucose, so it is not impossible, and they do not cause vitamin K deficiency.
- A patient is prescribed amoxicillin but has a documented severe penicillin allergy. Why should the technician alert the pharmacist before dispensing?
- Amoxicillin is a controlled substance requiring a new prescription
- Amoxicillin is a penicillin-class antibiotic and is contraindicated in true penicillin allergy
- Amoxicillin requires refrigeration that the patient cannot provide
- Amoxicillin interacts with the patient's diet
Correct answer: Amoxicillin is a penicillin-class antibiotic and is contraindicated in true penicillin allergy
Amoxicillin is a penicillin-class (aminopenicillin) antibiotic, so it is contraindicated in patients with a true penicillin allergy due to the risk of a cross-reactive allergic or anaphylactic reaction. The pharmacist should be alerted so an alternative can be considered. The concern here is the documented allergy, not storage, scheduling, or diet.
- Furosemide is used to manage edema and heart failure. To which class of diuretics does furosemide belong?
- Loop diuretic
- Potassium-sparing diuretic
- Thiazide diuretic
- Osmotic diuretic
Correct answer: Loop diuretic
Furosemide (Lasix) is a loop diuretic that acts on the loop of Henle to produce strong diuresis, making it useful for edema and heart failure. Like other loop diuretics it can lower potassium. Thiazides act at the distal tubule, potassium-sparing diuretics block aldosterone, and osmotic diuretics such as mannitol work by a different mechanism.
- Pseudoephedrine is found in some decongestant products. Which patient condition makes pseudoephedrine a contraindication or strong caution the technician should flag?
- Lactose intolerance
- A history of eczema
- Mild seasonal allergies
- Uncontrolled hypertension
Correct answer: Uncontrolled hypertension
Pseudoephedrine is a sympathomimetic decongestant that can raise blood pressure and heart rate, so it should be used with caution or avoided in patients with uncontrolled hypertension. Mild allergies, eczema, and lactose intolerance are not contraindications to pseudoephedrine. Such concerns should be referred to the pharmacist.
- A patient asks the technician what type of drug ibuprofen is. Ibuprofen belongs to which medication class?
- Corticosteroid
- Nonsteroidal anti-inflammatory drug
- Opioid analgesic
- Muscle relaxant
Correct answer: Nonsteroidal anti-inflammatory drug
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that reduces pain, inflammation, and fever by inhibiting cyclooxygenase (COX) enzymes. It is not an opioid, a corticosteroid, or a muscle relaxant. NSAIDs can irritate the stomach and affect the kidneys, especially with long-term use.
- A patient taking lisinopril is also prescribed ibuprofen for chronic pain. Why might this combination be flagged?
- Ibuprofen requires the lisinopril to be refrigerated
- Ibuprofen makes lisinopril a controlled substance
- The two drugs must be taken at exactly the same time
- NSAIDs can reduce the blood-pressure-lowering effect of the ACE inhibitor and stress the kidneys
Correct answer: NSAIDs can reduce the blood-pressure-lowering effect of the ACE inhibitor and stress the kidneys
NSAIDs such as ibuprofen can blunt the antihypertensive effect of ACE inhibitors like lisinopril and, when combined, may impair kidney function, especially in older or volume-depleted patients. This pharmacodynamic interaction should be flagged for the pharmacist. It has nothing to do with controlled-substance status, timing rules, or refrigeration.
- Atorvastatin and ezetimibe are sometimes used together for cholesterol management. Atorvastatin lowers LDL by inhibiting which enzyme?
- Xanthine oxidase
- Cyclooxygenase
- Acetylcholinesterase
- HMG-CoA reductase
Correct answer: HMG-CoA reductase
Atorvastatin lowers LDL cholesterol by inhibiting HMG-CoA reductase, the rate-limiting enzyme in cholesterol synthesis in the liver. Cyclooxygenase is the target of NSAIDs, acetylcholinesterase is inhibited by certain Alzheimer drugs, and xanthine oxidase is the target of allopurinol, so those are unrelated to statins.
- Two products are described as therapeutically equivalent and rated AB in the FDA Orange Book. What does therapeutic equivalence mean?
- The products are pharmaceutically equivalent and bioequivalent, so they can be expected to have the same clinical effect and safety profile
- The products differ in active ingredient strength but share a brand name
- The products are both brand-name only and cannot be substituted
- The products have completely different active ingredients but similar effects
Correct answer: The products are pharmaceutically equivalent and bioequivalent, so they can be expected to have the same clinical effect and safety profile
Therapeutically equivalent products are pharmaceutically equivalent (same active ingredient, strength, dosage form, and route) and bioequivalent, so they are expected to produce the same clinical effect and safety profile and can be substituted. The FDA assigns AB ratings in the Orange Book to identify such products. Therapeutic equivalence does not apply to products with different active ingredients or strengths.
- Gabapentin is frequently prescribed for nerve-related conditions. Which of the following is a recognized indication for gabapentin?
- Neuropathic pain and seizures
- Bacterial pneumonia
- High cholesterol
- Acid reflux
Correct answer: Neuropathic pain and seizures
Gabapentin is indicated for neuropathic pain, such as postherpetic neuralgia, and as an adjunct for partial seizures. It is not an antibiotic, a lipid-lowering agent, or an acid-reducing drug. A common side effect counseled to patients is drowsiness or dizziness, especially when starting therapy.
- A patient asks why oxycodone, a Schedule II controlled substance, is regulated more strictly than cough syrups containing codeine. What characteristic defines a Schedule II controlled substance under the federal Controlled Substances Act?
- A potential for abuse less than Schedule III with accepted medical use, limited to small amounts of narcotics
- No currently accepted medical use in the United States and a high potential for abuse
- A low potential for abuse relative to other scheduled drugs and accepted medical use
- A high potential for abuse with a currently accepted medical use, where abuse may lead to severe psychological or physical dependence
Correct answer: A high potential for abuse with a currently accepted medical use, where abuse may lead to severe psychological or physical dependence
A Schedule II controlled substance has a high potential for abuse along with a currently accepted medical use, and its abuse may lead to severe psychological or physical dependence. This is what separates it from Schedule I, which has no accepted medical use, and from lower schedules where abuse potential and dependence risk decline. Drugs such as oxycodone, hydromorphone, fentanyl, and amphetamine fall in Schedule II.
- A new prescription arrives with the DEA number AP1234563 for a prescriber whose last name is Patel. Using the standard check-digit method, what is the calculated check digit, and is the number valid?
- Check digit is 1; the number is invalid
- Check digit is 7; the number is invalid
- Check digit is 5; the number is valid
- Check digit is 3; the number is valid
Correct answer: Check digit is 3; the number is valid
The check digit is 3, which matches the final digit of AP1234563, so the number is valid. Using the digits 1234563, add the 1st, 3rd, and 5th digits (1+3+5=9); add the 2nd, 4th, and 6th digits and multiply by two ((2+4+6)×2=24); then add those results (9+24=33). The last digit of that sum, 3, must equal the seventh digit of the DEA number. The first letter should also be a valid registrant type and the second letter should match the first letter of the registrant's last name.
- Which two-step screening should a pharmacy technician perform first when visually verifying that a prescriber's DEA number is legitimate, before applying the check-digit math?
- Confirm the first letter is a valid registrant-type letter and the second letter matches the first letter of the prescriber's last name
- Confirm the number matches the patient's insurance BIN and PCN
- Confirm the number begins with the letters US and ends in an even number
- Confirm the number has exactly nine digits and no letters
Correct answer: Confirm the first letter is a valid registrant-type letter and the second letter matches the first letter of the prescriber's last name
Verifying a DEA number begins by confirming the first letter identifies a valid registrant type (such as A, B, F, or G for practitioners and hospitals, or M for a mid-level practitioner) and that the second letter matches the first letter of the registrant's last name. After that visual check, the technician applies the check-digit formula. A DEA number is always two letters followed by seven digits, so a nine-digit, all-numeric format would itself be invalid.
- A community pharmacy needs to place an order for a Schedule II controlled substance from its wholesaler using paper records rather than the electronic system. Which DEA form is required for this order?
- DEA Form 106
- DEA Form 224
- DEA Form 222
- DEA Form 41
Correct answer: DEA Form 222
DEA Form 222 is the order form required for the purchase or transfer of Schedule I and Schedule II controlled substances when a paper process is used. Form 224 is the pharmacy's registration application, Form 106 reports theft or significant loss, and Form 41 documents the destruction of controlled substances. Form 222 is specifically the procurement record for the most tightly controlled schedules.
- A pharmacy wants to order Schedule II controlled substances electronically instead of using paper Form 222. What system, and what security technology, makes this possible?
- The National Provider Identifier (NPI) registry, which uses a username and password
- The Prescription Drug Monitoring Program (PDMP), which uses a shared state database login
- MedWatch, which uses an FDA-issued electronic submission portal
- The Controlled Substance Ordering System (CSOS), which uses a digital certificate and Public Key Infrastructure
Correct answer: The Controlled Substance Ordering System (CSOS), which uses a digital certificate and Public Key Infrastructure
The Controlled Substance Ordering System (CSOS) lets registrants order Schedule I and II controlled substances electronically as an equivalent to paper Form 222. CSOS relies on a DEA-issued digital certificate and Public Key Infrastructure (PKI) technology, with each order signed using a digital signature. Paper Form 222 remains an available option, so CSOS use is optional rather than mandatory.
- A prescriber writes a Schedule II prescription that notes 'may be refilled twice.' How should the pharmacy technician handle the refill instruction?
- Enter two refills exactly as written since the prescriber authorized them
- Disregard the refill note because federal law prohibits refills on Schedule II prescriptions
- Allow refills only if the patient pays cash for each fill
- Allow up to five refills within six months like Schedule III drugs
Correct answer: Disregard the refill note because federal law prohibits refills on Schedule II prescriptions
Federal law prohibits any refills on a Schedule II prescription, so the refill note cannot be honored and each new supply requires a new prescription. This is a key difference from Schedule III, IV, and V drugs, which may be refilled. A prescriber may instead issue multiple sequential Schedule II prescriptions with 'do not fill until' dates, but a standard refill authorization is never valid for a Schedule II drug.
- How does a Schedule III controlled substance prescription differ from a Schedule II prescription with respect to refills under federal law?
- A Schedule III prescription may be refilled up to five times within six months, while a Schedule II prescription may not be refilled at all
- Both may be refilled up to five times within six months
- A Schedule III prescription may be refilled an unlimited number of times within one year
- A Schedule III prescription may not be refilled, while a Schedule II prescription may be refilled twice
Correct answer: A Schedule III prescription may be refilled up to five times within six months, while a Schedule II prescription may not be refilled at all
A Schedule III controlled substance prescription may be refilled up to five times within six months of the issue date, whereas a Schedule II prescription cannot be refilled at all. After five refills or six months, whichever comes first, a Schedule III prescription requires a new authorization. Schedule IV substances follow the same five-refills-in-six-months rule as Schedule III.
- Over a 30-day period a customer has already purchased 7.5 grams of pseudoephedrine base at a retail pharmacy. They now want to buy another 2 grams. Under the Combat Methamphetamine Epidemic Act, what is the maximum they may purchase, and may this sale proceed?
- The 30-day limit is 7.5 grams, so no further sale is allowed
- The 30-day retail limit is 9 grams, so only an additional 1.5 grams may be sold and the 2-gram request must be reduced or refused
- The 30-day limit is 3.6 grams, so the sale must be refused
- The 30-day limit is 9 grams, so the full 2 grams may be sold
Correct answer: The 30-day retail limit is 9 grams, so only an additional 1.5 grams may be sold and the 2-gram request must be reduced or refused
The federal 30-day limit for retail pseudoephedrine purchases is 9 grams of base per purchaser. With 7.5 grams already purchased, only 1.5 grams remain available in the 30-day window, so a 2-gram request cannot be filled in full. The lower 7.5-gram figure applies specifically to mail-order and mobile-vendor sales, not standard retail.
- The FDA announces a recall of a sterile injectable that was distributed contaminated, with a reasonable probability that its use will cause serious adverse health consequences or death. Which recall classification does this represent?
- Class II recall
- Market withdrawal
- Class I recall
- Class III recall
Correct answer: Class I recall
This is a Class I recall, the most serious category, defined as a situation in which there is a reasonable probability that use of or exposure to the product will cause serious adverse health consequences or death. A Class II recall involves temporary or medically reversible effects with remote risk of serious harm, and a Class III recall involves products unlikely to cause adverse health effects but that violate labeling or manufacturing rules.
- A pharmacy receives two FDA recall notices. One is for an oral tablet that is slightly under its labeled strength but is not used for a life-threatening condition; the other is for a product whose label has a minor printing error unlikely to cause any harm. How are these recalls classified?
- The under-strength non-critical product is a Class II recall and the harmless labeling error is a Class III recall
- Both are Class III recalls
- Both are Class I recalls
- The under-strength product is Class III and the labeling error is Class II
Correct answer: The under-strength non-critical product is a Class II recall and the harmless labeling error is a Class III recall
The under-strength tablet that is not used to treat a life-threatening condition is a Class II recall, because it may cause temporary or medically reversible effects with only a remote chance of serious harm. The minor labeling error unlikely to cause any adverse health consequence is a Class III recall. Class I is reserved for products that could cause serious harm or death.
- A pharmacy technician identifies an unexpected serious adverse drug reaction in a patient and the pharmacist wants to report it directly to the FDA. Which FDA program is used for this voluntary reporting of adverse events and product problems?
Correct answer: MedWatch
MedWatch is the FDA's safety information and adverse event reporting program used by health professionals and consumers to voluntarily report serious adverse events, product quality problems, and medication errors. REMS is a risk-management requirement attached to certain high-risk drugs, CSOS is the electronic ordering system for controlled substances, and the PDMP tracks dispensed controlled substances at the state level.
- A high-risk medication can only be dispensed after the prescriber, pharmacy, and patient complete specific enrollment and monitoring steps required by the FDA to ensure the drug's benefits outweigh its risks. What is this FDA-mandated requirement called?
- A black box warning
- A New Drug Application (NDA)
- A Risk Evaluation and Mitigation Strategy (REMS)
- A package insert monograph
Correct answer: A Risk Evaluation and Mitigation Strategy (REMS)
A Risk Evaluation and Mitigation Strategy (REMS) is an FDA-required safety program for certain medications with serious safety concerns, designed to ensure the benefits of the drug outweigh its risks. A REMS may include a medication guide, a communication plan, and Elements to Assure Safe Use (ETASU) such as prescriber certification, pharmacy enrollment, and patient monitoring or registry requirements. A black box warning conveys risk information but does not impose enrollment or dispensing controls.
- In the context of preventing medication errors, what is the primary purpose of writing drug names using tall man (mixed-case) lettering, such as hydrOXYzine and hydrALAZINE?
- To draw attention to the dissimilar portions of look-alike drug names and reduce name confusion
- To indicate that a drug is a controlled substance requiring extra documentation
- To show that a medication is on the high-alert list maintained by ISMP
- To shorten long drug names so they fit on prescription labels
Correct answer: To draw attention to the dissimilar portions of look-alike drug names and reduce name confusion
Tall man lettering uppercases and bolds the differing letters within similar drug names so the dissimilar parts stand out, which helps prevent selecting the wrong product among look-alike names. It is a name-differentiation strategy maintained by ISMP and the FDA, not a labeling shorthand, a controlled-substance flag, or a high-alert designation.
- A patient safety committee defines a category of drugs as those that carry a heightened risk of causing significant patient harm when used in error. Which term best describes this category?
- High-alert medications
- Legend drugs
- Sentinel drugs
- Orphan drugs
Correct answer: High-alert medications
High-alert medications are drugs that bear a heightened risk of causing significant patient harm when they are used in error, even though mistakes with them may or may not be more common than with other drugs. Legend drugs simply means prescription-only drugs, orphan drugs treat rare diseases, and 'sentinel drugs' is not a recognized safety category.
- Which of the following is the best description of USP General Chapter <797>?
- Standards for the labeling and storage of controlled substances
- Standards for sterile compounding intended to prevent microbial contamination of compounded sterile preparations
- Standards for nonsterile compounding of creams, capsules, and oral liquids
- Standards for handling hazardous drugs to protect healthcare workers
Correct answer: Standards for sterile compounding intended to prevent microbial contamination of compounded sterile preparations
USP <797> establishes the minimum standards for compounding sterile preparations to minimize the risk of microbial, particulate, and chemical contamination and protect patients. Hazardous-drug handling is the focus of USP <800>, nonsterile compounding is covered by USP <795>, and controlled-substance handling is governed by DEA regulations.
- Which of the following best states the primary purpose of USP General Chapter <800>?
- To regulate the recordkeeping of Schedule II controlled substances
- To define beyond-use dates for nonsterile creams and ointments
- To set sterility standards for IV admixtures
- To protect healthcare personnel, patients, and the environment when handling hazardous drugs
Correct answer: To protect healthcare personnel, patients, and the environment when handling hazardous drugs
USP <800> describes practice and quality standards for handling hazardous drugs to promote patient safety, worker safety, and environmental protection, and it applies to both sterile and nonsterile hazardous-drug handling. Sterility of admixtures falls under <797>, nonsterile BUDs fall under <795>, and controlled-substance recordkeeping is a DEA matter.
- A pharmacy is implementing a multi-pronged strategy to reduce dispensing errors. Which combination of measures is most consistent with recognized error-prevention practice?
- Storing all medications alphabetically by brand name regardless of look-alike risk
- Relying on a single experienced technician to verify all prescriptions without interruption checks
- Using tall man lettering, bar-code scanning at the point of dispensing, and independent double checks on high-alert drugs
- Increasing the font size on labels and asking technicians to work faster during peak hours
Correct answer: Using tall man lettering, bar-code scanning at the point of dispensing, and independent double checks on high-alert drugs
Layering independent safeguards such as tall man lettering, bar-code verification, and independent double checks for high-alert medications builds redundancy so that a single slip is more likely to be caught before it reaches the patient. Working faster, relying on one unchecked verifier, or shelving look-alike products together all increase rather than decrease error risk.
- Which of the following best describes USP General Chapter <795>?
- It governs only the handling of antineoplastic hazardous drugs
- It governs nonsterile compounding, including creams, ointments, capsules, and oral liquids
- It governs the storage temperatures of refrigerated vaccines
- It governs the sterile compounding of injectable products
Correct answer: It governs nonsterile compounding, including creams, ointments, capsules, and oral liquids
USP <795> sets the standards for compounding nonsterile preparations such as topical creams, ointments, capsules, and oral liquids, including the assignment of beyond-use dates. Sterile injectables fall under <797>, hazardous drugs under <800>, and vaccine storage under separate cold-chain and manufacturer guidance.
- Within compounding standards, what does the term 'beyond-use date' (BUD) refer to?
- The date or time after which a compounded preparation should not be used, stored, or transported
- The date a commercial drug was manufactured
- The manufacturer's expiration date printed on a stock bottle
- The date a controlled substance must be reported to the DEA
Correct answer: The date or time after which a compounded preparation should not be used, stored, or transported
A beyond-use date is the date or time beyond which a compounded preparation must not be used, stored, or transported, and it is assigned by the pharmacy based on USP standards. It differs from a manufacturer's expiration date, which applies to commercially manufactured products under stability testing, and it has nothing to do with a manufacturing or DEA reporting date.
- Which of the following medication classes is most consistently included on ISMP's list of high-alert medications used in acute care settings?
- Insulin
- Topical hydrocortisone cream
- Over-the-counter antacids
- Oral acetaminophen tablets
Correct answer: Insulin
Insulin is a classic high-alert medication because dosing errors can cause severe hypoglycemia and significant patient harm. The ISMP high-alert list also includes classes such as anticoagulants, opioids, and concentrated electrolytes, whereas oral acetaminophen, topical hydrocortisone, and OTC antacids carry comparatively low risk of catastrophic harm from a single error.
- A technician is comparing USP <797> and USP <795>. Which statement correctly distinguishes the two chapters?
- <797> covers sterile compounding while <795> covers nonsterile compounding
- <797> covers controlled substances while <795> covers vaccines
- <797> covers nonsterile compounding while <795> covers sterile compounding
- Both chapters cover only hazardous drug handling
Correct answer: <797> covers sterile compounding while <795> covers nonsterile compounding
USP <797> addresses sterile compounding to prevent microbial contamination of injectables and other sterile products, while USP <795> addresses nonsterile compounding such as creams, ointments, and oral liquids. Hazardous-drug handling is the domain of <800>, and neither chapter governs controlled substances or vaccine cold chain.
- In a 'tech-check-tech' (TCT) program, what activity is a qualified, specially trained pharmacy technician permitted to perform?
- Perform the final verification of another technician's filling or restocking work in approved settings
- Make a clinical decision to change a prescribed dose
- Diagnose a patient's condition before dispensing
- Counsel a patient on a new prescription's side effects
Correct answer: Perform the final verification of another technician's filling or restocking work in approved settings
In a tech-check-tech model, an appropriately trained and verified technician checks the accuracy of another technician's product-filling or cart-fill/restocking work, typically under defined state-board rules and pharmacist oversight. It does not authorize patient counseling, clinical dose changes, or diagnosis, all of which remain professional responsibilities of the pharmacist.
- Under USP <795>, a pharmacy compounds a nonaqueous oral liquid and has no stability information specific to the formulation. Which default maximum beyond-use date applies?
- 14 days
- 30 days
- 180 days
- 90 days
Correct answer: 90 days
For a nonaqueous oral liquid compounded under USP <795> without supporting stability data, the default maximum beyond-use date is 90 days. Nonpreserved aqueous preparations default to a much shorter BUD, while other nonaqueous dosage forms may default up to 180 days, so neither 14 nor 180 days fits an oral liquid.
- Which of the following pairs is the clearest example of look-alike/sound-alike (LASA) drug names that warrant extra error-prevention safeguards?
- Lisinopril and furosemide
- Amoxicillin and ibuprofen
- Hydroxyzine and hydralazine
- Aspirin and metformin
Correct answer: Hydroxyzine and hydralazine
Hydroxyzine and hydralazine are a well-known look-alike/sound-alike pair because their names appear and sound similar yet they are entirely different drugs, making them a frequent mix-up risk. The other pairs share little orthographic or phonetic similarity, so they are not classic LASA examples and do not carry the same confusion risk.
- In sterile compounding, what does the abbreviation CSP stand for?
- Clinical safety protocol
- Controlled substance prescription
- Certified sterile product
- Compounded sterile preparation
Correct answer: Compounded sterile preparation
CSP stands for compounded sterile preparation, the term USP <797> uses for products such as IV admixtures and injectables made under sterile conditions. It is not a controlled-substance prescription, a clinical safety protocol, or a manufacturer's certified product.
- How is a medication error best defined for patient-safety purposes?
- Any preventable event that may cause or lead to inappropriate medication use or patient harm while the medication is in the control of a provider, pharmacy, or patient
- Only an event in which a patient is hospitalized as a result of a drug
- Any side effect that occurs even when a drug is used correctly
- Only an error that is reported to the FDA
Correct answer: Any preventable event that may cause or lead to inappropriate medication use or patient harm while the medication is in the control of a provider, pharmacy, or patient
A medication error is any preventable event that may cause or lead to inappropriate medication use or patient harm while the medication is in the control of a healthcare professional, patient, or consumer. This definition captures errors at any stage and whether or not harm actually reaches the patient, distinguishing it from an adverse drug reaction that occurs with correct use, and it is not limited to hospitalizations or reported events.
- Under USP <797>, a Category 1 compounded sterile preparation is prepared in a segregated compounding area. What is the maximum beyond-use date when the preparation is stored at controlled room temperature?
- 4 days
- 24 hours
- 60 days
- 12 hours
Correct answer: 12 hours
A Category 1 CSP under USP <797> has a maximum beyond-use date of 12 hours at controlled room temperature and 24 hours refrigerated, reflecting the more limited environmental controls of a segregated compounding area. The 4-day and 60-day limits apply to Category 2 CSPs prepared under greater facility controls.
- A pharmacy stores concentrated potassium chloride injection, a high-alert medication, in the same bin as a similar-looking diluent. Which corrective action most directly reduces the risk associated with this high-alert drug?
- Increase the order quantity so the product is always in stock
- Move the product to an unlabeled overflow shelf to save space
- Train staff to dispense the product more quickly during busy periods
- Separate and clearly label the storage location and apply auxiliary warnings and an independent double check before dispensing
Correct answer: Separate and clearly label the storage location and apply auxiliary warnings and an independent double check before dispensing
Physically separating the high-alert product, adding distinct labeling and warnings, and requiring an independent double check directly target the storage and selection risks that make concentrated electrolytes dangerous. Stocking more units, hiding it on an unlabeled shelf, or pushing for faster dispensing would leave the underlying error risk unaddressed or worsen it.
- A technician must understand which USP chapter applies when a hazardous antineoplastic drug is compounded as a nonsterile oral suspension. Which chapter primarily governs the worker-protection requirements for handling that hazardous drug?
- USP <71>
- USP <795> only
- USP <797> only
- USP <800>
Correct answer: USP <800>
USP <800> governs the safe handling of hazardous drugs to protect personnel and the environment, and it applies whether the hazardous drug is compounded as a sterile or a nonsterile preparation. While <795> would address the nonsterile compounding quality aspects, the hazardous-drug containment and worker-protection requirements come from <800>; <797> covers sterile work and <71> addresses sterility testing.
- A pharmacy wants to reduce the chance that a technician selects the wrong product when two strengths of the same high-alert anticoagulant sit side by side. Which combination of strategies best addresses this risk?
- Allowing only verbal confirmation of strength between two technicians
- Removing all labels so staff memorize bin locations
- Shelf separation, tall man or bold strength differentiation, and bar-code verification at selection
- Keeping both strengths in one unlabeled bin to save space
Correct answer: Shelf separation, tall man or bold strength differentiation, and bar-code verification at selection
Separating the products, visually differentiating the strengths with bold or tall man style cues, and verifying with bar-code scanning at the point of selection layer independent defenses against picking the wrong strength of a high-alert anticoagulant. Removing labels, relying on memory or verbal-only checks, or combining strengths in one unlabeled bin all defeat these safeguards.
- A prescription is written with the sig "1 tab PO bid." How should this be translated for the patient label?
- Take 1 tablet by mouth at bedtime
- Take 1 tablet by mouth three times daily
- Take 1 tablet under the tongue twice daily
- Take 1 tablet by mouth twice daily
Correct answer: Take 1 tablet by mouth twice daily
Take 1 tablet by mouth twice daily is correct. In pharmacy sig codes, "PO" is the abbreviation for the Latin per os, meaning "by mouth," and "bid" (bis in die) means twice a day. "At bedtime" would be hs, "under the tongue" is SL (sublingual), and three times daily is tid, so those translations do not match this sig.
- A pharmacy technician reads the sig "ii gtt OD qid." What does the "qid" portion of this sig direct?
- Four times a day
- Once daily
- Every other day
- Every 4 hours
Correct answer: Four times a day
Four times a day is correct. The sig abbreviation "qid" stands for the Latin quater in die, meaning four times daily. It is distinct from "qod" (every other day, now discouraged), "qd"/daily (once a day), and "q4h" (every 4 hours). In this sig, "ii gtt OD qid" means instill 2 drops in the right eye four times a day.
- A prescriber writes "1 cap PO tid with meals." In standard medical and pharmacy abbreviation, how often is the dose taken?
- At bedtime only
- Three times a day
- Once a day
- Twice a day
Correct answer: Three times a day
Three times a day is correct. The abbreviation "tid" comes from the Latin ter in die, meaning three times a day. It should not be confused with "bid" (twice daily) or "qd"/daily (once daily). When tid is paired with "with meals," doses are commonly spaced around breakfast, lunch, and dinner.
- A prescription sig reads "1 tab PO q6h prn pain." What does the abbreviation "prn" tell the technician about how the medication is taken?
- The medication is taken only as needed
- The medication must be taken before meals
- The medication is taken at bedtime
- The medication is taken on a fixed schedule regardless of symptoms
Correct answer: The medication is taken only as needed
Taken only as needed is correct. On a prescription, "prn" stands for the Latin pro re nata, meaning "as needed" or "as the situation arises." Here the full sig directs 1 tablet by mouth every 6 hours as needed for pain, so the patient takes it only when pain is present rather than on a fixed schedule.
- A sig states "1 tab PO ac." Using standard pharmacy abbreviations, when should the patient take this dose?
- Every morning
- Before meals
- At bedtime
- After meals
Correct answer: Before meals
Before meals is correct. The pharmacy abbreviation "ac" comes from the Latin ante cibum, meaning "before meals." Its counterpart "pc" (post cibum) means "after meals," "hs" means at bedtime, and "qam" means every morning. Distinguishing ac from pc is important for medications whose absorption or effect depends on timing relative to food.
- While interpreting a handwritten sig, a technician sees the Roman numeral "iss" for the quantity to dispense per dose. What number does "iss" represent?
- One
- One and one-half
- Five
- Two
Correct answer: One and one-half
One and one-half is correct. In the Roman numeral system used in pharmacy, the suffix "ss" denotes one-half, so "iss" equals 1+21=1.5. By comparison, i is 1, ii is 2, and v is 5. Recognizing apothecary-style Roman numerals is essential when reading older or handwritten prescription sigs.
- A pharmacy technician is verifying the 11-digit National Drug Code printed on a manufacturer's stock bottle. Which three segments make up an NDC, in order?
- Labeler code, product code, package code
- DEA number, product code, package code
- Therapeutic class, strength code, package code
- Manufacturer lot, expiration date, package size
Correct answer: Labeler code, product code, package code
Labeler code, product code, and package code is correct. The National Drug Code (NDC) is a unique identifier assigned to each drug product, divided into three segments: the labeler code (assigned by the FDA to the manufacturer or distributor), the product code (drug, strength, and dosage form), and the package code (package size and type). Lot numbers, expiration dates, and DEA numbers are separate identifiers and are not part of the NDC.
- An 11-digit NDC always follows which numeric segment pattern?
Correct answer: 5-4-2
5-4-2 is correct. The standardized 11-digit NDC format used for billing follows a 5-4-2 pattern: a 5-digit labeler code, a 4-digit product code, and a 2-digit package code. Manufacturer labels may print a 10-digit NDC in 4-4-2, 5-3-2, or 5-4-1 patterns, but each of those is converted to the uniform 5-4-2 format by inserting a leading zero into the appropriate segment.
- A stock bottle lists the NDC as 12345-678-90, a 5-3-2 format. What is the correct 11-digit (5-4-2) NDC?
- 01234-5678-90
- 12345-0678-90
- 12345-678-090
- 12345-6780-90
Correct answer: 12345-0678-90
12345-0678-90 is correct. A 10-digit NDC in 5-3-2 format is converted to 11 digits by adding a leading zero to the middle (product) segment, turning the 3-digit "678" into the 4-digit "0678." The result is 12345-0678-90, which now follows the standard 5-4-2 pattern. Adding the zero to the first segment would apply only to a 4-4-2 format, and adding it to the last segment applies only to a 5-4-1 format.
- A physician orders 1500 mL of normal saline to infuse over 12 hours by infusion pump. What flow rate in mL/hr should the technician help set?
- 150 mL/hr
- 125 mL/hr
- 75 mL/hr
- 100 mL/hr
Correct answer: 125 mL/hr
125 mL/hr is correct. IV flow rate in milliliters per hour equals the total volume divided by the total time in hours: 1500 mL÷12 hr=125 mL/hr. An infusion pump is programmed in mL/hr, so no drop factor is needed for this calculation.
- An order calls for 1000 mL of D5W to infuse over 8 hours using tubing with a drop factor of 15 gtt/mL. What is the drip rate in drops per minute (rounded to the nearest whole drop)?
- 31 gtt/min
- 42 gtt/min
- 21 gtt/min
- 15 gtt/min
Correct answer: 31 gtt/min
31 gtt/min is correct. The drip rate formula is (total volume in mL multiplied by the drop factor in gtt/mL) divided by the total time in minutes. Here that is (1000 mL×15 gtt/mL)÷480 min (8 hours × 60), which equals 15000÷480=31.25, rounded to 31 gtt/min. The drop factor printed on the tubing package is required because gravity tubing is counted in drops, not mL/hr.
- A technician selects IV tubing labeled "microdrip" for a precise pediatric infusion. What drop factor does microdrip tubing deliver?
- 20 gtt/mL
- 10 gtt/mL
- 15 gtt/mL
- 60 gtt/mL
Correct answer: 60 gtt/mL
60 gtt/mL is correct. Microdrip (microbore) tubing delivers 60 drops per milliliter and is used for small or precise volumes such as pediatric and neonatal infusions. Macrodrip tubing delivers larger drops, typically 10, 15, or 20 gtt/mL, for routine adult infusions. A useful check: with 60 gtt/mL microdrip tubing, the gtt/min value equals the mL/hr value.
- A prescription reads "levothyroxine 0.5 mg PO daily." To select the correct tablet strength, the technician converts the dose to micrograms-compatible units. How many milligrams is 0.5 g, and how many mg is 500 micrograms?
- 0.5 g equals 5000 mg; 500 mcg equals 0.05 mg
- 0.5 g equals 50 mg; 500 mcg equals 5 mg
- 0.5 g equals 5 mg; 500 mcg equals 50 mg
- 0.5 g equals 500 mg; 500 mcg equals 0.5 mg
Correct answer: 0.5 g equals 500 mg; 500 mcg equals 0.5 mg
0.5 g equals 500 mg and 500 mcg equals 0.5 mg is correct. In the metric system each step is a factor of 1000: to convert grams to milligrams you multiply by 1000, so 0.5 g x 1000 equals 500 mg. To convert micrograms to milligrams you divide by 1000, so 500 mcg divided by 1000 equals 0.5 mg. Keeping these 1000-fold relationships straight prevents serious dosing errors.
- A patient picks up a 10 mL vial of U-100 insulin and injects 35 units once daily. Approximately how many days will one vial last?
- 100 days
- 10 days
- 35 days
- 28 days
Correct answer: 28 days
28 days is correct. A U-100 insulin product contains 100 units per mL, so a 10 mL vial holds 10×100=1000 units. Dividing 1000÷35=28.57, which is truncated to a 28-day supply because you cannot bill for a partial day. Days supply for insulin always starts from total units in the vial, not the milliliter volume.
- A prescription for an ophthalmic solution directs "2 gtt in each eye twice daily" and is dispensed in a 30 mL bottle. Using the standard estimate of 20 drops per mL, what days supply should be entered?
- 60 days
- 30 days
- 15 days
- 75 days
Correct answer: 75 days
75 days is correct. The bottle contains 30 mL×20 gtt/mL=600 drops. The patient uses 2 drops per eye, both eyes, twice daily: 2×2×2=8 drops per day. Dividing 600÷8=75-day supply. Drops-per-mL conversion is essential for billing days supply on eye drops.
- A maintenance prescription reads "metformin 500 mg, 1 tablet PO tid, dispense 90 tablets." What days supply should be entered?
- 30 days
- 45 days
- 60 days
- 90 days
Correct answer: 30 days
30 days is correct. "Tid" means three times a day, so the patient takes 3 tablets per day. Dividing the dispensed quantity 90÷3=30-day supply. Entering the wrong frequency (for example treating tid as once daily) would overstate the days supply and could delay a legitimate refill.
- A 240 mL volume of a flavored syrup weighs 300 g. What is the specific gravity of the syrup?
Correct answer: 1.25
1.25 is correct. Specific gravity is the weight of a substance divided by the weight of an equal volume of water, and because 1 mL of water weighs 1 g, it equals grams divided by milliliters for aqueous liquids. Here 300 g divided by 240 mL equals 1.25. A specific gravity greater than 1 indicates the syrup is denser than water, which is typical of high-sugar vehicles.
- A topical preparation contains 15 g of active drug in a total of 500 mL of solution. What is the percentage strength (weight/volume)?
Correct answer: 3%
3% is correct. Weight/volume percentage strength equals grams of solute per 100 mL of solution. Here 50015×100=3%, meaning 3 g per 100 mL. Percentage strength lets technicians compare concentrations and is the basis for many compounding and dilution calculations.
- An order specifies an epinephrine solution of 1:200 strength. Expressed as a percentage strength, what does 1:200 equal?
Correct answer: 0.5%
0.5% is correct. A ratio strength of 1:200 means 1 g in 200 mL (for a solid in liquid). To convert ratio strength to percentage strength, set up 200 mL1 g=100 mLx g, giving x=0.5 g per 100 mL, or 0.5%. Equivalently, 2001×100=0.5%.
- A compound is labeled 0.5% w/v. Expressed as a ratio strength, this concentration equals:
Correct answer: 1:200
1:200 is correct. A 0.5% w/v solution contains 0.5 g per 100 mL. To express this as a ratio strength of 1 g in x mL, 100÷0.5=200, so the strength is 1:200. Ratio strength is conventionally written so the first number is 1, and a larger second number means a more dilute preparation.
- A technician must prepare 500 g of a 40% ointment by mixing a 70% ointment with a 20% ointment using the alligation method. How many grams of each base are needed?
- 200 g of 70% and 300 g of 20%
- 150 g of 70% and 350 g of 20%
- 300 g of 70% and 200 g of 20%
- 250 g of 70% and 250 g of 20%
Correct answer: 200 g of 70% and 300 g of 20%
200 g of the 70% and 300 g of the 20% is correct. In alligation, the parts of each component are found by the difference across the desired strength: the 70% contributes 40−20=20 parts, and the 20% contributes 70−40=30 parts, for 50 total parts. For 500 g, the 70% is 5020×500=200 g and the 20% is 5030×500=300 g. Alligation is the standard method for blending two strengths to reach a target in between.
- A dry-powder antibiotic, when reconstituted, yields a final volume of 100 mL after adding 80 mL of sterile water as the diluent. What is the powder volume (the space the dry drug occupies)?
Correct answer: 20 mL
20 mL is correct. Powder volume is the difference between the final reconstituted volume and the volume of diluent added: 100 mL−80 mL=20 mL. Knowing the powder volume is important so the correct amount of diluent is added to hit the labeled final volume and concentration; adding the full final volume as diluent would overdilute the product.
- A patient requests the generic name for Nexium, a proton pump inhibitor used for GERD. Which generic name should the technician provide?
- Esomeprazole
- Pantoprazole
- Lansoprazole
- Famotidine

- A technician is asked for the generic name of Lasix, a loop diuretic. Which generic name should be provided?
- Furosemide
- Hydrochlorothiazide
- Spironolactone
- Bumetanide
Correct answer: Furosemide
Furosemide is the generic name for Lasix, a loop diuretic that works at the loop of Henle. Hydrochlorothiazide is a thiazide diuretic, spironolactone is a potassium-sparing diuretic, and bumetanide (Bumex) is a different loop diuretic.
- Which brand-name product corresponds to the generic drug duloxetine, used for depression and neuropathic pain?
- Effexor
- Cymbalta
- Wellbutrin
- Lexapro
Correct answer: Cymbalta
Cymbalta is the brand name for duloxetine, a serotonin-norepinephrine reuptake inhibitor (SNRI). Effexor is venlafaxine, Wellbutrin is bupropion, and Lexapro is escitalopram.
- A patient asks the technician for the generic name of Crestor, a cholesterol-lowering statin. Which generic name is correct?
- Pravastatin
- Simvastatin
- Rosuvastatin
- Lovastatin
Correct answer: Rosuvastatin
Rosuvastatin is the generic name for Crestor, an HMG-CoA reductase inhibitor (statin). Pravastatin (Pravachol), simvastatin (Zocor), and lovastatin (Mevacor) are other statins with different brand names.
- Losartan is prescribed for hypertension. Drugs whose generic names end in the suffix '-sartan' belong to which class?
- ACE inhibitors
- Beta-blockers
- Calcium channel blockers
- Angiotensin II receptor blockers (ARBs)
Correct answer: Angiotensin II receptor blockers (ARBs)
Angiotensin II receptor blockers (ARBs) is correct because the '-sartan' stem identifies this class, which includes losartan, valsartan, and olmesartan. ARBs block the angiotensin II receptor, whereas the '-pril' stem (lisinopril) identifies ACE inhibitors.
- Pantoprazole is dispensed to reduce gastric acid. Which drug class does pantoprazole belong to?
- Proton pump inhibitor
- H2-receptor antagonist
- Antacid
- Prokinetic agent
Correct answer: Proton pump inhibitor
Pantoprazole is a proton pump inhibitor (PPI); the '-prazole' suffix signals this class, which blocks the H+/K+ ATPase proton pump in gastric parietal cells. H2-receptor antagonists end in '-tidine' (famotidine), and antacids neutralize acid directly.
- Clonazepam is used for seizures and anxiety. Drugs whose generic names end in '-azepam' or '-azolam' generally belong to which class?
- Barbiturates
- Benzodiazepines
- SSRIs
- Antipsychotics
Correct answer: Benzodiazepines
Benzodiazepines is correct because the '-azepam' and '-azolam' stems identify this class, which includes clonazepam, lorazepam, and alprazolam. Benzodiazepines enhance GABA activity and are scheduled controlled substances.
- Ondansetron is given to prevent nausea and vomiting. Which mechanism of action best describes ondansetron?
- Dopamine D2 receptor antagonist
- Histamine H1 receptor antagonist
- Serotonin 5-HT3 receptor antagonist
- Substance P/NK1 antagonist
Correct answer: Serotonin 5-HT3 receptor antagonist
Ondansetron is a serotonin 5-HT3 receptor antagonist (the '-setron' stem signals this class), blocking serotonin at receptors in the gut and CNS to prevent nausea. Aprepitant is an NK1 antagonist, and promethazine works on H1 and dopamine receptors.
- Cephalexin is dispensed for a bacterial infection. To which class of antibiotics does cephalexin belong?
- Macrolides
- Fluoroquinolones
- Tetracyclines
- Cephalosporins
Correct answer: Cephalosporins
Cephalexin is a cephalosporin antibiotic; the 'cef-' or 'ceph-' stem identifies this beta-lactam class. Macrolides end in '-mycin' (azithromycin), fluoroquinolones end in '-floxacin', and tetracyclines end in '-cycline'.
- Pravastatin lowers cholesterol. Drugs ending in the suffix '-statin' inhibit which enzyme?
- HMG-CoA reductase
- Phosphodiesterase
- Cyclooxygenase
- Xanthine oxidase
Correct answer: HMG-CoA reductase
Statins inhibit HMG-CoA reductase, the rate-limiting enzyme in cholesterol synthesis; the '-statin' stem identifies this class. Xanthine oxidase is inhibited by allopurinol, and cyclooxygenase is inhibited by NSAIDs.
- Metformin is first-line therapy for type 2 diabetes. What is its primary mechanism of action?
- Stimulates insulin secretion from the pancreas
- Decreases hepatic glucose production and improves insulin sensitivity
- Blocks glucose reabsorption in the kidney
- Slows carbohydrate absorption in the gut
Correct answer: Decreases hepatic glucose production and improves insulin sensitivity
Metformin works by decreasing hepatic glucose production and improving peripheral insulin sensitivity, which is why it does not typically cause hypoglycemia on its own. Sulfonylureas stimulate insulin secretion, SGLT2 inhibitors block renal glucose reabsorption, and alpha-glucosidase inhibitors slow gut carbohydrate absorption.
- Warfarin is an oral anticoagulant. What is its mechanism of action?
- Directly inhibits thrombin
- Inhibits factor Xa directly
- Inhibits vitamin K-dependent clotting factor synthesis
- Activates antithrombin III
Correct answer: Inhibits vitamin K-dependent clotting factor synthesis
Warfarin inhibits the synthesis of vitamin K-dependent clotting factors (II, VII, IX, and X) by blocking vitamin K epoxide reductase. Dabigatran directly inhibits thrombin, apixaban directly inhibits factor Xa, and heparin activates antithrombin III.
- Sumatriptan is used for acute migraine. What is its mechanism of action?
- Dopamine receptor antagonist
- NMDA receptor antagonist
- Beta-adrenergic agonist
- Serotonin 5-HT1 receptor agonist causing vasoconstriction
Correct answer: Serotonin 5-HT1 receptor agonist causing vasoconstriction
Sumatriptan is a serotonin 5-HT1 receptor agonist that causes cranial vasoconstriction and reduces neurogenic inflammation to abort migraines; the '-triptan' stem identifies this class. It is not a dopamine antagonist or beta-agonist.
- Allopurinol is used for chronic gout management. By what mechanism does it lower uric acid?
- Inhibits xanthine oxidase to reduce uric acid production
- Increases renal excretion of uric acid
- Breaks down existing uric acid crystals
- Blocks reabsorption of urate in the tubule
Correct answer: Inhibits xanthine oxidase to reduce uric acid production
Allopurinol inhibits xanthine oxidase, the enzyme that converts purines into uric acid, thereby reducing uric acid production. Probenecid increases renal excretion of uric acid (uricosuric), and pegloticase enzymatically breaks down existing uric acid.
- Lisinopril is prescribed for hypertension and heart failure. What is its primary mechanism of action?
- Blocks angiotensin II receptors
- Inhibits angiotensin-converting enzyme (ACE)
- Blocks calcium channels
- Antagonizes aldosterone receptors
Correct answer: Inhibits angiotensin-converting enzyme (ACE)
Lisinopril inhibits angiotensin-converting enzyme (ACE), reducing the conversion of angiotensin I to angiotensin II and lowering blood pressure. ARBs (such as losartan) block angiotensin II receptors, which is a distinct mechanism.
- Albuterol provides quick relief of bronchospasm in asthma. What is its mechanism of action?
- Muscarinic receptor antagonist
- Leukotriene receptor antagonist
- Beta-2 adrenergic receptor agonist
- Corticosteroid
Correct answer: Beta-2 adrenergic receptor agonist
Albuterol is a short-acting beta-2 adrenergic receptor agonist (SABA) that relaxes bronchial smooth muscle to provide rapid bronchodilation. Ipratropium is a muscarinic antagonist, montelukast is a leukotriene antagonist, and inhaled corticosteroids reduce inflammation.
- Famotidine is used to reduce stomach acid. What is its mechanism of action?
- Blocks the proton pump in parietal cells
- Neutralizes existing gastric acid
- Forms a protective barrier over ulcers
- Antagonizes histamine H2 receptors on parietal cells
Correct answer: Antagonizes histamine H2 receptors on parietal cells
Famotidine antagonizes histamine H2 receptors on gastric parietal cells, decreasing acid secretion; the '-tidine' stem identifies H2 blockers. Proton pump inhibitors block the proton pump directly, and antacids chemically neutralize acid already present.
- A patient on warfarin is started on an antibiotic. Why should the technician flag concurrent use with trimethoprim-sulfamethoxazole?
- It can potentiate warfarin and increase bleeding risk
- It decreases warfarin's effect, raising clot risk
- It chelates warfarin in the gut
- It causes a disulfiram-like reaction
Correct answer: It can potentiate warfarin and increase bleeding risk
Trimethoprim-sulfamethoxazole can potentiate warfarin's anticoagulant effect by inhibiting its metabolism, increasing INR and bleeding risk. This is a clinically significant interaction that warrants pharmacist review, not a chelation or disulfiram-type effect.
- A patient taking digoxin is also prescribed a loop diuretic. Why is this combination flagged for monitoring?
- The diuretic raises digoxin levels directly
- Diuretic-induced hypokalemia increases digoxin toxicity risk
- The combination causes serotonin syndrome
- It chelates digoxin and reduces absorption
Correct answer: Diuretic-induced hypokalemia increases digoxin toxicity risk
Loop diuretics can cause hypokalemia, and low potassium increases the risk of digoxin toxicity because digoxin and potassium compete at the Na+/K+ ATPase pump. This is why potassium levels are monitored when these drugs are combined.
- A patient on a monoamine oxidase inhibitor (MAOI) asks about taking an over-the-counter decongestant. Why should the technician flag pseudoephedrine?
- It blocks the MAOI from working
- It reduces the decongestant effect
- It can cause a hypertensive crisis with MAOIs
- It causes excessive sedation
Correct answer: It can cause a hypertensive crisis with MAOIs
Combining pseudoephedrine with an MAOI can precipitate a hypertensive crisis because MAOIs increase available catecholamines and pseudoephedrine is a sympathomimetic. This dangerous interaction requires pharmacist intervention.
- A patient takes levothyroxine and is dispensed calcium carbonate for heartburn. Why should the technician counsel on timing?
- Calcium increases levothyroxine absorption
- The two cause serotonin syndrome
- Calcium inactivates the thyroid hormone permanently
- Calcium can decrease levothyroxine absorption if taken together
Correct answer: Calcium can decrease levothyroxine absorption if taken together
Calcium carbonate can decrease levothyroxine absorption when taken at the same time, so the doses should be separated by at least four hours. The interaction reduces, rather than increases, the thyroid medication's effectiveness.
- A patient on clopidogrel (an antiplatelet drug) is prescribed omeprazole. Why might this combination be flagged?
- Omeprazole may reduce clopidogrel's activation and effectiveness
- Omeprazole increases clopidogrel's antiplatelet effect
- The combination causes hyperkalemia
- It leads to a disulfiram reaction
Correct answer: Omeprazole may reduce clopidogrel's activation and effectiveness
Omeprazole inhibits CYP2C19, the enzyme that converts clopidogrel into its active form, which may reduce clopidogrel's antiplatelet effectiveness. Pantoprazole is often preferred because it has less effect on this enzyme.
- Two CNS depressants, an opioid and a benzodiazepine, are prescribed together. Why does this combination carry an FDA boxed warning?
- It causes excessive stimulation
- Additive CNS and respiratory depression can be fatal
- The benzodiazepine blocks the opioid
- It causes serotonin syndrome
Correct answer: Additive CNS and respiratory depression can be fatal
Combining opioids with benzodiazepines produces additive central nervous system and respiratory depression that can be fatal, which is why the FDA requires a boxed warning. The risk is sedation and respiratory failure, not stimulation.
- A patient starting amlodipine should be counseled about which common side effect?
- Persistent dry cough
- Hyperkalemia
- Peripheral edema (ankle swelling)
- Photosensitivity
Correct answer: Peripheral edema (ankle swelling)
Peripheral edema, particularly ankle swelling, is a common side effect of amlodipine and other dihydropyridine calcium channel blockers due to vasodilation. A dry cough is characteristic of ACE inhibitors, not calcium channel blockers.
- A patient on long-term prednisone should be monitored for which common adverse effect?
- Hypoglycemia
- Bradycardia
- Hypotension
- Hyperglycemia and increased infection risk
Correct answer: Hyperglycemia and increased infection risk
Long-term corticosteroids like prednisone can cause hyperglycemia and increase infection risk due to immunosuppression. Other effects include osteoporosis, weight gain, and adrenal suppression; corticosteroids tend to raise, not lower, blood glucose.
- A patient starting tamsulosin for benign prostatic hyperplasia should be counseled about which side effect?
- Orthostatic hypotension and dizziness
- Severe constipation
- Hyperkalemia
- Photosensitivity
Correct answer: Orthostatic hypotension and dizziness
Tamsulosin, an alpha-1 blocker, can cause orthostatic hypotension and dizziness because of vasodilation, especially with the first dose. Patients should rise slowly from sitting or lying positions to avoid falls.
- A patient is prescribed an opioid such as oxycodone for pain. Which preventive counseling point should the technician relay regarding a common side effect?
- Take a stimulant before each dose
- A stool softener or laxative may be needed to prevent constipation
- Avoid all fluids
- Take it only on an empty stomach
Correct answer: A stool softener or laxative may be needed to prevent constipation
Opioids commonly cause constipation, so a stool softener or laxative may be recommended to prevent it because opioid-induced constipation does not resolve with tolerance. This is standard counseling for opioid therapy.
- A patient taking metronidazole asks about the most common counseling point. Besides alcohol avoidance, which side effect should be mentioned?
- Bright red urine
- Permanent tooth staining
- A metallic taste in the mouth
- Blue-green vision
Correct answer: A metallic taste in the mouth
A metallic taste in the mouth is a recognized side effect of metronidazole, along with the well-known need to avoid alcohol due to a disulfiram-like reaction. Tooth staining is associated with tetracyclines in children, not metronidazole.
- Reconstituted amoxicillin-clavulanate (Augmentin) oral suspension should be stored under which condition after mixing?
- Frozen
- Room temperature only
- In a warm location
- Refrigerated
Correct answer: Refrigerated
Reconstituted amoxicillin-clavulanate suspension should be refrigerated to maintain stability and is discarded after the labeled period (typically 10 days). Freezing is not recommended because it can affect the product's consistency.
- Most insulin vials and pens that are unopened (not yet in use) should be stored under which condition?
- Refrigerated
- Frozen solid
- At room temperature only
- In direct sunlight
Correct answer: Refrigerated
Unopened insulin should be refrigerated until first use to preserve potency, and it must never be frozen because freezing denatures the protein. Once in use, many insulins can be kept at room temperature for a limited period.
- A medication label states 'Store at controlled room temperature.' Which temperature range does this typically refer to per USP standards?
- 2 to 8 degrees Celsius
- Below 0 degrees Celsius
- 20 to 25 degrees Celsius
- 30 to 40 degrees Celsius
Correct answer: 20 to 25 degrees Celsius
Controlled room temperature is defined by USP as approximately 20 to 25 degrees Celsius (68 to 77 degrees Fahrenheit). Refrigeration is 2 to 8 degrees Celsius, and freezing is below 0 degrees Celsius.
- Which of the following is considered a narrow therapeutic index (NTI) drug requiring close monitoring?
- Amoxicillin
- Loratadine
- Acetaminophen
- Lithium
Correct answer: Lithium
Lithium is a classic narrow therapeutic index drug requiring routine blood-level monitoring because the gap between therapeutic and toxic concentrations is small. Amoxicillin, loratadine, and standard acetaminophen dosing have wide safety margins.
- A prescription is written for a medication available as an enteric-coated tablet. What is the primary purpose of the enteric coating?
- To protect the drug from stomach acid and delay release until the intestine
- To mask an unpleasant taste only
- To allow the tablet to be crushed easily
- To make the tablet dissolve faster in the mouth
Correct answer: To protect the drug from stomach acid and delay release until the intestine
An enteric coating protects an acid-sensitive drug from stomach acid and delays dissolution until the tablet reaches the more alkaline intestine. Because of this, enteric-coated tablets should not be crushed or chewed, as that would defeat the coating.
- Insulin lispro is taken with meals, while insulin glargine is given once daily. How does insulin lispro differ from insulin glargine?
- Lispro is long-acting; glargine is rapid-acting
- Lispro is rapid-acting; glargine is long-acting (basal)
- Both are rapid-acting
- Both are intermediate-acting
Correct answer: Lispro is rapid-acting; glargine is long-acting (basal)
Insulin lispro is a rapid-acting insulin taken at mealtimes to cover glucose from food, whereas insulin glargine is a long-acting (basal) insulin providing steady background coverage. Their onset and duration profiles are intentionally different.
- A patient with a documented sulfa allergy is prescribed a new medication. Which of the following should the technician flag for pharmacist review?
- Amoxicillin
- Azithromycin
- Sulfamethoxazole-trimethoprim
- Doxycycline
Correct answer: Sulfamethoxazole-trimethoprim
Sulfamethoxazole-trimethoprim contains a sulfonamide and should be flagged for a patient with a documented sulfa allergy. Amoxicillin (a penicillin), azithromycin (a macrolide), and doxycycline (a tetracycline) are not sulfonamides.
- A patient asks which OTC analgesic is safest for occasional pain if they have a history of gastric ulcers and are advised to avoid NSAIDs. Which agent is typically recommended?
- Ibuprofen
- Naproxen
- Aspirin
- Acetaminophen
Correct answer: Acetaminophen
Acetaminophen is generally recommended for patients who must avoid NSAIDs because it does not have the gastric irritation and bleeding risk associated with NSAIDs such as ibuprofen, naproxen, and aspirin. Acetaminophen works centrally and is not an NSAID.
- A patient asks the technician for the generic name of Nexium, a proton pump inhibitor used for GERD. Which generic name should the technician provide?
- Omeprazole
- Esomeprazole
- Pantoprazole
- Lansoprazole
Correct answer: Esomeprazole
Correct answer: Esomeprazole. Esomeprazole is the generic name for the brand Nexium, a proton pump inhibitor. Omeprazole is Prilosec, pantoprazole is Protonix, and lansoprazole is Prevacid; all are PPIs but correspond to different brand names.
- Which auxiliary label is most appropriate for a prescription of doxycycline, a tetracycline antibiotic?
- Avoid prolonged exposure to sunlight
- Take on an empty stomach only
- May cause discoloration of urine
- Shake well before using
Correct answer: Avoid prolonged exposure to sunlight
Correct answer: Avoid prolonged exposure to sunlight. Doxycycline can cause photosensitivity, so a 'sun-sensitivity' auxiliary label is appropriate. It may be taken with food to reduce GI upset, so an empty-stomach-only label is not required, and it is not associated with the other listed warnings as a primary counseling point.
- A prescriber orders amoxicillin/clavulanate. What is the role of the clavulanate component?
- It is a beta-lactamase inhibitor that protects amoxicillin from degradation
- It increases renal excretion of amoxicillin
- It is a second antibiotic targeting gram-negative rods
- It masks the bitter taste of amoxicillin
Correct answer: It is a beta-lactamase inhibitor that protects amoxicillin from degradation
Correct answer: It is a beta-lactamase inhibitor that protects amoxicillin from degradation. Clavulanate (clavulanic acid) inhibits bacterial beta-lactamase enzymes, preventing them from breaking down amoxicillin and extending its spectrum. It does not affect renal excretion, is not itself an antibacterial agent, and does not function as a flavoring.
- Which controlled-substance schedule applies to alprazolam, a benzodiazepine used for anxiety?
- Schedule II
- Schedule IV
- Schedule III
- Schedule V
Correct answer: Schedule IV
Correct answer: Schedule IV. Alprazolam (Xanax) is a Schedule IV controlled substance, the category that includes most benzodiazepines. Schedule II contains drugs like oxycodone, Schedule III includes products such as certain testosterone formulations, and Schedule V includes low-strength codeine cough preparations.
- A patient is prescribed a fentanyl transdermal patch for chronic pain. What is the most appropriate counseling point regarding application?
- Cut the patch in half to adjust the dose if needed
- Apply heat over the patch to speed absorption
- Apply to clean, dry, non-irritated skin and rotate the application site
- Apply the patch only to the soles of the feet
Correct answer: Apply to clean, dry, non-irritated skin and rotate the application site
Correct answer: Apply to clean, dry, non-irritated skin and rotate the application site. Fentanyl patches should be placed on intact, clean, dry skin with site rotation to reduce irritation. Patches must never be cut, and applying external heat increases absorption and risk of overdose; the soles of the feet are not an appropriate site.
- Which dosage form is described as a solid form intended to dissolve slowly in the mouth to release medication locally to the throat?
- Enteric-coated tablet
- Sublingual tablet
- Troche or lozenge
- Caplet
Correct answer: Troche or lozenge
Correct answer: Troche or lozenge. A troche (lozenge) is a solid dosage form designed to dissolve slowly in the mouth, releasing drug locally. An enteric-coated tablet is swallowed and dissolves in the intestine, a sublingual tablet dissolves quickly under the tongue for systemic effect, and a caplet is simply a capsule-shaped swallowed tablet.
- A patient brings in a prescription for the brand drug Eliquis. What is its generic name?
- Rivaroxaban
- Dabigatran
- Edoxaban
- Apixaban
Correct answer: Apixaban
Correct answer: Apixaban. Apixaban is the generic name for Eliquis, a direct oral anticoagulant (factor Xa inhibitor). Rivaroxaban is Xarelto, dabigatran is Pradaxa (a direct thrombin inhibitor), and edoxaban is Savaysa; all are anticoagulants but correspond to different brands.
- Levothyroxine tablets are available in many strengths that are color-coded by the manufacturer. Why is this color coding clinically useful?
- It helps reduce dispensing errors among the many available strengths
- It indicates the drug's expiration date
- It shows whether the tablet is a brand or generic product
- It signals the controlled-substance schedule
Correct answer: It helps reduce dispensing errors among the many available strengths
Correct answer: It helps reduce dispensing errors among the many available strengths. Levothyroxine comes in numerous closely spaced strengths, and manufacturer color coding helps technicians and pharmacists distinguish them to prevent strength selection errors. Color does not convey expiration, brand/generic status, or any scheduling information.
- Which of the following insulin products is classified as a long-acting (basal) insulin?
- Insulin glargine
- Insulin aspart
- Insulin lispro
- Regular insulin
Correct answer: Insulin glargine
Correct answer: Insulin glargine. Insulin glargine (Lantus, Basaglar) is a long-acting basal insulin providing a relatively flat, prolonged effect. Insulin aspart and insulin lispro are rapid-acting mealtime insulins, and regular insulin is short-acting.
- Which look-alike/sound-alike (LASA) pair is correctly matched and represents a recognized medication safety concern?
- Metformin and metronidazole
- Hydralazine and hydroxyzine
- Lisinopril and levothyroxine
- Amoxicillin and amlodipine
Correct answer: Hydralazine and hydroxyzine
Correct answer: Hydralazine and hydroxyzine. Hydralazine (an antihypertensive) and hydroxyzine (an antihistamine) are a well-known look-alike/sound-alike pair due to similar spelling and pronunciation. The other listed pairs are not recognized LASA pairs and treat unrelated conditions.
- A pharmacy receives an order for an enteric-coated aspirin tablet. What is the purpose of the enteric coating?
- To make the tablet dissolve faster in the mouth
- To allow the tablet to be crushed for feeding tubes
- To increase the controlled-substance schedule
- To delay drug release until the tablet reaches the small intestine, reducing stomach irritation
Correct answer: To delay drug release until the tablet reaches the small intestine, reducing stomach irritation
Correct answer: To delay drug release until the tablet reaches the small intestine, reducing stomach irritation. Enteric coatings resist stomach acid so the drug is released in the intestine, decreasing gastric irritation. Such tablets dissolve more slowly, should not be crushed, and coating has nothing to do with scheduling.
- Which of the following medications is available over the counter (OTC) at a nonprescription strength?
- Loratadine 10 mg
- Atorvastatin 10 mg
- Metformin 500 mg
- Lisinopril 10 mg
Correct answer: Loratadine 10 mg
Correct answer: Loratadine 10 mg. Loratadine, a second-generation antihistamine, is available OTC. Atorvastatin, metformin, and lisinopril are prescription-only medications and are not sold over the counter.
- A patient is prescribed sumatriptan for acute migraine. To which drug class does sumatriptan belong?
- Ergot alkaloid
- NSAID
- Serotonin (5-HT1) receptor agonist (triptan)
- Beta-blocker
Correct answer: Serotonin (5-HT1) receptor agonist (triptan)
Correct answer: Serotonin (5-HT1) receptor agonist (triptan). Sumatriptan is a triptan that activates 5-HT1 receptors to abort migraine attacks. Ergot alkaloids are a separate older migraine class, NSAIDs reduce inflammation, and beta-blockers are used for migraine prophylaxis rather than acute treatment.
- Which route of administration is indicated by the abbreviation 'SL' on a prescription?
- Subcutaneous
- Sublimaze
- Slow IV push
- Sublingual
Correct answer: Sublingual
Correct answer: Sublingual. The abbreviation 'SL' means sublingual, meaning the medication is placed under the tongue. Subcutaneous is abbreviated 'SubQ' or 'SC', Sublimaze is a brand name for fentanyl, and slow IV push is not what 'SL' designates.
- A patient receives a prescription for clindamycin and reports a history of diarrhea with prior antibiotics. Which serious adverse effect should be associated with clindamycin?
- Photosensitivity rash
- Tendon rupture
- Cinchonism
- Clostridioides difficile-associated diarrhea/colitis
Correct answer: Clostridioides difficile-associated diarrhea/colitis
Correct answer: Clostridioides difficile-associated diarrhea/colitis. Clindamycin is strongly associated with C. difficile infection and pseudomembranous colitis. Photosensitivity is linked to tetracyclines/fluoroquinolones, tendon rupture to fluoroquinolones, and cinchonism to quinine, not clindamycin.
- Which of the following is the correct generic name for the brand drug Zofran, an antiemetic?
- Ondansetron
- Promethazine
- Metoclopramide
- Prochlorperazine
Correct answer: Ondansetron
Correct answer: Ondansetron. Ondansetron is the generic name for Zofran, a 5-HT3 antagonist antiemetic. Promethazine (Phenergan), metoclopramide (Reglan), and prochlorperazine (Compazine) are other antiemetics but correspond to different brand names.
- A patient is prescribed prednisone for an inflammatory condition. Which counseling point is most appropriate?
- Take with food to reduce stomach upset and do not stop abruptly if used long term
- Take only on an empty stomach at bedtime
- Avoid all dairy products while taking it
- It is safe to double the dose if a dose is missed
Correct answer: Take with food to reduce stomach upset and do not stop abruptly if used long term
Correct answer: Take with food to reduce stomach upset and do not stop abruptly if used long term. Prednisone, a corticosteroid, should be taken with food to limit GI irritation and tapered rather than stopped suddenly after prolonged use to avoid adrenal insufficiency. The other statements are inaccurate counseling.
- Which medication class does the suffix '-pril' identify, as in lisinopril and enalapril?
- ACE inhibitors
- Angiotensin receptor blockers
- Calcium channel blockers
- Beta-blockers
Correct answer: ACE inhibitors
Correct answer: ACE inhibitors. The stem '-pril' identifies angiotensin-converting enzyme (ACE) inhibitors such as lisinopril and enalapril. ARBs use the '-sartan' stem, calcium channel blockers commonly end in '-dipine', and beta-blockers end in '-olol'.
- A reconstituted oral antibiotic suspension is labeled to be discarded after 10 days. What does this 'discard after' date most directly represent?
- The manufacturer's original expiration date
- The date the prescription was written
- The beyond-use date (BUD) after reconstitution
- The earliest refill date
Correct answer: The beyond-use date (BUD) after reconstitution
Correct answer: The beyond-use date (BUD) after reconstitution. Once a powder is reconstituted into a suspension, its stability changes, so a beyond-use date is assigned, often shorter than the manufacturer expiration. It is not the original expiration, the prescribing date, or a refill date.
- Which of the following medications belongs to the angiotensin receptor blocker (ARB) class?
- Lisinopril
- Losartan
- Metoprolol
- Amlodipine
Correct answer: Losartan
Correct answer: Losartan. Losartan is an ARB, identified by the '-sartan' stem, used for hypertension. Lisinopril is an ACE inhibitor, metoprolol is a beta-blocker, and amlodipine is a calcium channel blocker.
- A patient picks up a prescription for the brand drug Lyrica. What is its generic name?
- Pregabalin
- Gabapentin
- Duloxetine
- Topiramate
Correct answer: Pregabalin
Correct answer: Pregabalin. Pregabalin is the generic name for Lyrica, used for neuropathic pain and seizures. Gabapentin (Neurontin), duloxetine (Cymbalta), and topiramate (Topamax) are used for related conditions but correspond to different brands.
- Which statement best describes the difference between a suspension and a solution as liquid dosage forms?
- A solution must always be refrigerated, while a suspension never requires refrigeration
- A suspension is always sterile, while a solution is always nonsterile
- A solution must be shaken well before each use, while a suspension does not
- A suspension contains undissolved particles and must be shaken before use; a solution is a fully dissolved mixture
Correct answer: A suspension contains undissolved particles and must be shaken before use; a solution is a fully dissolved mixture
Correct answer: A suspension contains undissolved particles and must be shaken before use; a solution is a fully dissolved mixture. Suspensions have particles that settle and require shaking, whereas solutions are homogeneous with the drug fully dissolved. Refrigeration, sterility, and shaking requirements depend on the specific product, not the dosage-form definitions given in the distractors.
- Sublingual nitroglycerin is prescribed for acute angina. How quickly is it generally expected to begin relieving chest pain?
- After 24 hours of continuous use
- Within a few minutes
- Only after 2 to 3 days
- It does not act until taken with food
Correct answer: Within a few minutes
Correct answer: Within a few minutes. Sublingual nitroglycerin dissolves under the tongue and is absorbed rapidly, typically relieving angina within minutes. It is not a delayed-onset or food-dependent product, which makes the other choices incorrect.
- Which of the following medications is classified as a Schedule II controlled substance?
- Diazepam
- Pregabalin
- Oxycodone
- Codeine-containing cough syrup (low strength)
Correct answer: Oxycodone
Correct answer: Oxycodone. Oxycodone is a Schedule II controlled substance with high abuse potential and an accepted medical use. Diazepam is Schedule IV, pregabalin is Schedule V, and certain low-strength codeine cough preparations are Schedule V.
- A patient is dispensed warfarin and asks why their tablets are different colors at different strengths. What is the best explanation?
- The color indicates the manufacturer's profit margin
- Color shows how close the tablet is to expiring
- Each warfarin strength is a distinct color to help identify the dose and prevent errors
- Different colors mean different active ingredients
Correct answer: Each warfarin strength is a distinct color to help identify the dose and prevent errors
Correct answer: Each warfarin strength is a distinct color to help identify the dose and prevent errors. Warfarin uses standardized color coding by strength to reduce the chance of dosing mistakes for this narrow therapeutic index drug. Color does not reflect cost, expiration, or a change in active ingredient.
- Which medication is an inhaled short-acting beta-2 agonist (SABA) used as a rescue inhaler for acute asthma symptoms?
- Fluticasone
- Tiotropium
- Albuterol
- Montelukast
Correct answer: Albuterol
Correct answer: Albuterol. Albuterol is a short-acting beta-2 agonist used as a quick-relief rescue inhaler. Fluticasone is an inhaled corticosteroid (controller), tiotropium is a long-acting anticholinergic, and montelukast is an oral leukotriene receptor antagonist.
- A prescription reads 'apply BID.' How should the technician interpret 'BID' for the directions?
- Three times daily
- Every other day
- Twice daily
- At bedtime
Correct answer: Twice daily
Correct answer: Twice daily. The abbreviation 'BID' means twice a day. Three times daily is 'TID', every other day is 'QOD', and at bedtime is 'HS', which makes the other interpretations incorrect.
- Which medication is a biguanide commonly used as first-line therapy for type 2 diabetes and carries a boxed warning for lactic acidosis?
- Glipizide
- Metformin
- Sitagliptin
- Pioglitazone
Correct answer: Metformin
Correct answer: Metformin. Metformin is a biguanide and the usual first-line agent for type 2 diabetes; it carries a boxed warning for rare lactic acidosis. Glipizide is a sulfonylurea, sitagliptin is a DPP-4 inhibitor, and pioglitazone is a thiazolidinedione.
- A patient is prescribed the brand drug Advair, used for asthma and COPD. What two-drug combination does it contain?
- Two short-acting beta agonists
- An antibiotic plus a decongestant
- An antihistamine plus a leukotriene blocker
- An inhaled corticosteroid plus a long-acting beta agonist
Correct answer: An inhaled corticosteroid plus a long-acting beta agonist
Correct answer: An inhaled corticosteroid plus a long-acting beta agonist. Advair combines fluticasone (an inhaled corticosteroid) with salmeterol (a long-acting beta agonist) for maintenance therapy. It is not a combination of two SABAs, an antibiotic/decongestant, or an antihistamine/leukotriene product.
- Which auxiliary label should accompany a dispensed bottle of liquid amoxicillin suspension prepared in the pharmacy?
- Take on an empty stomach only
- May discolor tears and contact lenses
- Avoid sunlight exposure
- Shake well before using; refrigerate
Correct answer: Shake well before using; refrigerate
Correct answer: Shake well before using; refrigerate. A reconstituted amoxicillin suspension contains settling particles and is typically refrigerated, so a 'shake well' and 'refrigerate' label is appropriate. It may be taken without regard to meals, and the tear-discoloration and photosensitivity warnings apply to other drugs such as rifampin and tetracyclines.
- Which of the following is the generic name for the brand drug Tylenol?
- Acetaminophen
- Ibuprofen
- Naproxen
- Aspirin
Correct answer: Acetaminophen
Correct answer: Acetaminophen. Acetaminophen is the generic name for Tylenol, an analgesic/antipyretic. Ibuprofen (Advil/Motrin), naproxen (Aleve), and aspirin are separate analgesics with different brand names and mechanisms.
- A patient on long-term proton pump inhibitor therapy should be counseled about a potential reduction in the absorption of which nutrient?
- Vitamin C
- Vitamin K
- Vitamin B12
- Niacin
Correct answer: Vitamin B12
Correct answer: Vitamin B12. Long-term PPI use can reduce gastric acid needed to release and absorb vitamin B12, potentially leading to deficiency. PPIs are not specifically associated with impaired absorption of vitamin C, vitamin K, or niacin in the same way.
- Which medication is a selective serotonin reuptake inhibitor (SSRI) used for depression and anxiety, available as the brand Lexapro?
- Bupropion
- Venlafaxine
- Amitriptyline
- Escitalopram
Correct answer: Escitalopram
Correct answer: Escitalopram. Escitalopram is an SSRI marketed as Lexapro. Bupropion is an atypical antidepressant (NDRI), venlafaxine is an SNRI, and amitriptyline is a tricyclic antidepressant, so they belong to different antidepressant classes.
- A vial of insulin currently in use is generally assigned a beyond-use date of how long at appropriate storage once opened, per common manufacturer guidance?
- About 3 days
- About 28 days
- About 6 months
- It never expires once opened
Correct answer: About 28 days
Correct answer: About 28 days. Many insulin products in use are assigned a beyond-use date of approximately 28 days after first use, after which they should be discarded even if some remains. The other intervals do not reflect typical insulin in-use stability guidance.
- Which of the following describes the correct meaning of the abbreviation 'PRN' in prescription directions?
- Before meals
- As needed
- By mouth
- Right eye
Correct answer: As needed
Correct answer: As needed. 'PRN' means the medication is taken as needed. Before meals is 'AC', by mouth is 'PO', and right eye is 'OD', which makes the other interpretations incorrect.
- A retail pharmacy is logging a sale of a pseudoephedrine product in its electronic logbook. Which piece of information is NOT required to be recorded under the Combat Methamphetamine Epidemic Act?
- The purchaser's date of birth
- The purchaser's name and address
- The product name and quantity sold
- The date and time of the transaction
Correct answer: The purchaser's date of birth
Correct answer: The purchaser's date of birth. The Combat Methamphetamine Epidemic Act requires the logbook to capture the product name, quantity, the purchaser's name and address, and the date and time of the sale, plus the purchaser's signature. The buyer's date of birth is verified from a photo ID at the point of sale but is not a mandated logbook field, which is why it is the correct answer to this exception question.
- Under federal law, what is the maximum length of time after the issue date that a Schedule III, IV, or V prescription remains valid for refills?
- 30 days
- Six months
- One year
- 90 days
Correct answer: Six months
Correct answer: Six months. Federal law allows Schedule III, IV, and V prescriptions to be filled or refilled for up to six months from the date the prescription was written, with a limit of five refills during that window. After six months elapse, the prescription expires regardless of remaining refills, distinguishing it from the one-year validity often allowed for many non-controlled prescriptions under state law.
- A pharmacy must keep records of controlled substance transactions available for inspection by the DEA. For how many years does federal law require these records to be retained?
- Three years
- Five years
- Two years
- Seven years
Correct answer: Two years
Correct answer: Two years. The federal Controlled Substances Act requires pharmacies to retain all controlled substance records, including inventories, receiving documents, and dispensing records, for a minimum of two years and to make them available for DEA inspection. Some states impose longer retention periods, but the federal minimum is two years.
- Under federal law, how often must a pharmacy take a complete inventory of all controlled substances on hand?
- Every six months
- Every year
- Every three months
- Every two years
Correct answer: Every two years
Correct answer: Every two years. The DEA requires each registrant to conduct a complete and accurate biennial (every two years) inventory of all controlled substances on hand, in addition to the initial inventory taken when first engaging in controlled substance activity. State boards of pharmacy may require more frequent counts, but federal law sets the biennial standard.
- When a pharmacy conducts its controlled substance inventory, how must Schedule II substances be counted compared with Schedule III through V substances?
- Schedule II must be an exact count; Schedule III-V may be estimated
- All schedules may be estimated
- All schedules must be exactly counted
- Schedule II may be estimated; Schedule III-V must be exact
Correct answer: Schedule II must be an exact count; Schedule III-V may be estimated
Correct answer: Schedule II must be an exact count; Schedule III-V may be estimated. Federal regulations require an exact physical count of all Schedule II substances during inventory. For Schedule III, IV, and V substances, an estimated count is permitted unless the container holds more than 1,000 dosage units, in which case an exact count is required.
- A patient brings in a prescription for a Schedule II medication, but the prescriber accidentally wrote the wrong patient's address. Under DEA guidance, which information on a Schedule II prescription may a pharmacist NEVER change after consulting the prescriber?
- The patient's address
- The prescriber's signature
- The dosage form
- The drug quantity
Correct answer: The prescriber's signature
Correct answer: The prescriber's signature. DEA policy permits pharmacists, after consultation with the prescriber, to add or change certain items on a Schedule II prescription such as the patient's address, drug strength, dosage form, or quantity. However, the pharmacist may never change the prescriber's signature, the name of the patient, the name of the drug (except a generic substitution per state law), or the date issued.
- Federal law allows a partial fill of a Schedule II prescription. If a pharmacy partially fills a Schedule II prescription at a patient's request, within how many days must the remaining quantity be dispensed?
- 72 hours
- Six months
- 30 days
- Seven days
Correct answer: 30 days
Correct answer: 30 days. Under the SUPPORT Act amendments to federal law, a Schedule II prescription may be partially filled at the request of the patient or prescriber, and the remaining portions may be dispensed within 30 days of the date the prescription was written. This differs from the older 72-hour rule that still applies to certain emergency and long-term-care situations.
- In a bona fide emergency, a prescriber may issue an oral order for a Schedule II controlled substance. Within how many days must the prescriber furnish a written, signed prescription to the pharmacy to cover that emergency dispensing?
- 72 hours (7 days)
- 48 hours
- 24 hours
- 7 days
Correct answer: 7 days
Correct answer: 7 days. Federal law permits oral emergency dispensing of a Schedule II drug limited to the amount needed to treat the emergency. The prescriber must then deliver a written, signed prescription to the pharmacy within 7 days. The pharmacist must note 'Authorization for Emergency Dispensing' on the oral order and notify the DEA if the written cover prescription is not received.
- A pharmacist receives a prescription for a controlled substance from a prescriber located in a different state. Under federal law, what determines whether the pharmacist may fill it?
- The prescriber must have a valid DEA registration and the prescription must comply with the laws of both states
- It may never be filled across state lines
- Only Schedule V drugs may cross state lines
- Federal law alone, ignoring state requirements
Correct answer: The prescriber must have a valid DEA registration and the prescription must comply with the laws of both states
Correct answer: The prescriber must have a valid DEA registration and the prescription must comply with the laws of both states. Federal law does not prohibit out-of-state controlled substance prescriptions, but the prescriber must hold a valid DEA registration and be acting within the usual course of professional practice. The pharmacy must also satisfy the controlled substance laws of both the prescriber's and the pharmacy's states.
- On DEA Form 222 or the electronic CSOS system, which schedules of controlled substances require this special ordering process?
- Schedule III, IV, and V
- Schedule I and II
- All schedules
- Schedule V only
Correct answer: Schedule I and II
Correct answer: Schedule I and II. The DEA Form 222 (and its electronic equivalent, the Controlled Substance Ordering System, or CSOS) is required for ordering and transferring Schedule I and II controlled substances. Schedule III through V substances may be ordered using ordinary invoices and do not require Form 222 or CSOS.
- How long must a pharmacy retain a completed DEA Form 222 and its associated records?
- One year
- Five years
- Two years
- Indefinitely
Correct answer: Two years
Correct answer: Two years. Records associated with DEA Form 222, like other controlled substance records, must be retained for a minimum of two years and kept available for DEA inspection. The form documents the transfer of Schedule II substances and must be maintained separately from other business records.
- Federal law requires that records of Schedule II controlled substances be maintained in what manner relative to other records?
- Combined with all prescription records
- Only in electronic form
- Combined with Schedule III-V records but separate from non-controlled records
- Separately from all other records
Correct answer: Separately from all other records
Correct answer: Separately from all other records. The DEA requires that all Schedule II controlled substance records be kept separate from all other records of the pharmacy. Schedule III through V records may either be kept separately or maintained in a readily retrievable form within other records, but Schedule II must always stand alone.
- Under the federal Health Insurance Portability and Accountability Act (HIPAA), the minimum necessary standard requires a pharmacy to do what?
- Limit use and disclosure of protected health information to the least amount needed for the purpose
- Disclose all available patient information when requested
- Obtain written consent before every dispensing
- Retain records for the patient's lifetime
Correct answer: Limit use and disclosure of protected health information to the least amount needed for the purpose
Correct answer: Limit use and disclosure of protected health information to the least amount needed for the purpose. HIPAA's minimum necessary standard requires covered entities like pharmacies to make reasonable efforts to limit the use, disclosure, and requests for protected health information to the minimum amount needed to accomplish the intended task, rather than sharing a patient's full record.
- Under HIPAA, what document must a pharmacy provide to patients describing how their protected health information may be used and disclosed?
- A Material Safety Data Sheet
- A Notice of Privacy Practices
- A patient package insert
- A Medication Guide
Correct answer: A Notice of Privacy Practices
Correct answer: A Notice of Privacy Practices. HIPAA requires covered entities such as pharmacies to provide each patient with a Notice of Privacy Practices that explains how the patient's protected health information may be used and disclosed and describes the patient's rights regarding that information. This is distinct from clinical documents like Medication Guides or package inserts.
- Federal law (OBRA '90) requires pharmacists to offer what service to Medicaid patients receiving new prescriptions?
- A free home delivery option
- A generic substitution
- Counseling on their medication (an offer to counsel)
- A 90-day supply
Correct answer: Counseling on their medication (an offer to counsel)
Correct answer: Counseling on their medication (an offer to counsel). The Omnibus Budget Reconciliation Act of 1990 (OBRA '90) requires pharmacists to offer counseling to Medicaid patients, a requirement most states have extended to all patients. It also mandates prospective drug utilization review and the maintenance of patient records, strengthening the pharmacist's clinical role.
- Which schedule of controlled substances has no accepted medical use in the United States and cannot be prescribed?
- Schedule II
- Schedule III
- Schedule V
- Schedule I
Correct answer: Schedule I
Correct answer: Schedule I. Schedule I substances, such as heroin and LSD, have a high potential for abuse and no currently accepted medical use in treatment in the United States, so they cannot be prescribed or dispensed by a pharmacy. Schedules II through V all contain drugs that have accepted medical uses and may be prescribed under appropriate controls.
- Among the controlled substance schedules, which schedule generally contains drugs with the LOWEST potential for abuse that still have accepted medical use?
- Schedule V
- Schedule II
- Schedule III
- Schedule IV
Correct answer: Schedule V
Correct answer: Schedule V. Among the schedules of drugs with accepted medical uses (II through V), Schedule V contains substances with the lowest potential for abuse, such as certain cough preparations with limited codeine and antidiarrheals like diphenoxylate/atropine. Abuse potential increases as the schedule number decreases, with Schedule II being the most tightly controlled.
- Certain Schedule V products, such as low-dose codeine cough syrups, may be sold without a prescription in some states. Which requirement applies to such a sale under federal law?
- Any cashier may complete the sale
- The sale must be made by or under the supervision of a pharmacist and recorded with purchaser information
- No record is required
- Only a physician may authorize the sale
Correct answer: The sale must be made by or under the supervision of a pharmacist and recorded with purchaser information
Correct answer: The sale must be made by or under the supervision of a pharmacist and recorded with purchaser information. Federal law permits limited over-the-counter sale of certain Schedule V products where state law allows, but the sale must be made by or under the supervision of a pharmacist, limited in quantity, and recorded in a bound book noting the purchaser's name and address, the product, the date, and the dispensing pharmacist.
- A pharmacy is destroying expired controlled substances on-site. Which DEA form is used to document the destruction of controlled substances?
- DEA Form 222
- DEA Form 224
- DEA Form 41
- DEA Form 106
Correct answer: DEA Form 41
Correct answer: DEA Form 41. The DEA Form 41 (Registrant Record of Controlled Substances Destroyed) is used to document the destruction of controlled substances. Form 222 orders Schedule II drugs, Form 224 is the pharmacy's registration application, and Form 106 reports theft or significant loss.
- Which DEA form must a pharmacy complete to apply for or renew its registration as a dispenser of controlled substances?
- DEA Form 363
- DEA Form 510
- DEA Form 225
- DEA Form 224
Correct answer: DEA Form 224
Correct answer: DEA Form 224. The DEA Form 224 is used by retail pharmacies, hospitals, and practitioners to apply for and renew their DEA registration to dispense controlled substances. Form 225 is for manufacturers and distributors, Form 363 is for narcotic treatment programs, and Form 510 relates to List I chemical registrants.
- How frequently must a pharmacy renew its DEA registration?
- Every three years
- Every year
- Every two years
- Every five years
Correct answer: Every three years
Correct answer: Every three years. A pharmacy's DEA registration must be renewed every three years using DEA Form 224a. This differs from the biennial (two-year) controlled substance inventory requirement, so it is important not to confuse the registration renewal cycle with the inventory cycle.
- Under federal law, the transfer of refill information for a controlled substance prescription between two pharmacies (one-time transfer) is permitted for which schedules?
- Schedule II only
- Schedule III, IV, and V
- All schedules including II
- Schedule V only
Correct answer: Schedule III, IV, and V
Correct answer: Schedule III, IV, and V. Federal law permits a one-time transfer of original prescription information for refill purposes for Schedule III, IV, and V controlled substances between pharmacies, provided both pharmacies share a real-time online database (in which case transfers up to the maximum refills are allowed). Schedule II prescriptions cannot be refilled and therefore cannot be transferred for refill.
- A controlled substance prescription must contain certain elements to be valid under federal law. Which of the following is a required element?
- The patient's insurance ID
- The pharmacy's NPI number
- The prescriber's DEA registration number
- The patient's Social Security number
Correct answer: The prescriber's DEA registration number
Correct answer: The prescriber's DEA registration number. A valid controlled substance prescription must include the prescriber's DEA registration number along with the date of issue, patient name and address, drug name, strength, dosage form, quantity, directions for use, and the prescriber's signature. Insurance IDs and Social Security numbers are not federal validity requirements.
- Under the federal Food, Drug, and Cosmetic Act, what term describes a drug whose strength, quality, or purity differs from what it is represented to possess, or that was prepared under unsanitary conditions?
- Misbranded
- Counterfeit
- Investigational
- Adulterated
Correct answer: Adulterated
Correct answer: Adulterated. The FD&C Act defines an adulterated drug as one whose strength, quality, or purity differs from the official standard, that contains a filthy or decomposed substance, or that was prepared, packed, or held under unsanitary conditions. Misbranding, by contrast, refers to false or misleading labeling rather than the physical quality of the product.
- Under the federal Food, Drug, and Cosmetic Act, a drug with false or misleading labeling, or labeling that lacks required information, is considered what?
- Misbranded
- Adulterated
- Recalled
- Exempt
Correct answer: Misbranded
Correct answer: Misbranded. The FD&C Act classifies a drug as misbranded if its labeling is false or misleading, fails to bear required information such as adequate directions for use, or is not labeled in accordance with the law. This is distinct from adulteration, which concerns the physical quality, purity, or manufacturing conditions of the product itself.
- The Durham-Humphrey Amendment of 1951 established which key distinction in drug regulation?
- The schedules of controlled substances
- The difference between prescription (legend) and over-the-counter drugs
- Child-resistant packaging requirements
- Orphan drug incentives
Correct answer: The difference between prescription (legend) and over-the-counter drugs
Correct answer: The difference between prescription (legend) and over-the-counter drugs. The Durham-Humphrey Amendment created the legal distinction between prescription drugs (which require the legend 'Rx only' and a practitioner's authorization) and over-the-counter drugs that may be sold directly to consumers. It also authorized oral prescriptions and refills for legend drugs.
- The Kefauver-Harris Amendment of 1962 was enacted largely in response to the thalidomide tragedy. What major requirement did it add for drug approval?
- Child-resistant packaging
- Tamper-evident packaging
- Proof of efficacy in addition to safety
- Generic substitution
Correct answer: Proof of efficacy in addition to safety
Correct answer: Proof of efficacy in addition to safety. The Kefauver-Harris Amendment of 1962, prompted by the thalidomide birth-defect tragedy, required drug manufacturers to prove that a drug was effective for its intended use, not merely safe, before it could be marketed. It also strengthened FDA oversight of clinical testing and adverse event reporting.
- Which federal agency is primarily responsible for approving new drugs and regulating drug labeling and manufacturing standards?
- The Drug Enforcement Administration (DEA)
- The Centers for Disease Control and Prevention (CDC)
- The Centers for Medicare and Medicaid Services (CMS)
- The Food and Drug Administration (FDA)
Correct answer: The Food and Drug Administration (FDA)
Correct answer: The Food and Drug Administration (FDA). The FDA approves new drugs, regulates labeling, sets manufacturing standards, and oversees drug safety and efficacy. The DEA enforces controlled substance laws, the CDC focuses on disease prevention, and CMS administers Medicare and Medicaid programs.
- Which federal agency administers and enforces the Controlled Substances Act, including registration of pharmacies that handle controlled substances?
- The DEA
- The FDA
- The FTC
- OSHA
Correct answer: The DEA
Correct answer: The DEA. The Drug Enforcement Administration administers and enforces the Controlled Substances Act, including registering manufacturers, distributors, pharmacies, and practitioners who handle controlled substances and investigating diversion. The FDA handles drug approval and labeling, while the FTC regulates trade practices and OSHA addresses workplace safety.
- A controlled substance prescription is electronically transmitted. Under DEA rules for electronic prescriptions for controlled substances (EPCS), what authentication is required of the prescriber at the time of signing?
- A single password only
- Two-factor authentication
- A faxed cover sheet
- A notarized signature
Correct answer: Two-factor authentication
Correct answer: Two-factor authentication. DEA regulations for electronic prescriptions for controlled substances require the prescriber to complete two-factor authentication at the time of signing, combining two of the following: something the prescriber knows (password), something they have (a token or smartphone app), or something they are (a biometric). This security safeguard protects against unauthorized prescribing.
- Under the Drug Supply Chain Security Act (DSCSA), what is transaction history (TH) intended to document?
- The patient's prescription refill history
- The pharmacy's controlled substance inventory
- The chain of ownership of a product from the manufacturer through each subsequent sale
- The prescriber's DEA registration history
Correct answer: The chain of ownership of a product from the manufacturer through each subsequent sale
Correct answer: The chain of ownership of a product from the manufacturer through each subsequent sale. Under the DSCSA, transaction history is a statement documenting each prior transaction back to the manufacturer, accompanying transaction information and a transaction statement. Together these elements allow the supply chain to trace a product and detect suspect or illegitimate drugs.
- A pharmacy technician notices that a manufacturer's drug package lacks a National Drug Code (NDC) number. What does the NDC identify?
- The controlled substance schedule
- The patient and prescriber
- The wholesaler's account number
- The manufacturer, product, and package size
Correct answer: The manufacturer, product, and package size
Correct answer: The manufacturer, product, and package size. The National Drug Code is a unique, three-segment number that identifies the labeler/manufacturer, the specific product (strength, dosage form, formulation), and the package size. It is required on drug packaging and is used for billing, inventory, and recall identification.
- Under federal law, who bears ultimate responsibility for the accuracy of a prescription dispensed by a pharmacy technician?
- The supervising pharmacist
- The pharmacy technician
- The prescriber
- The drug wholesaler
Correct answer: The supervising pharmacist
Correct answer: The supervising pharmacist. Although pharmacy technicians perform many tasks in filling prescriptions, the supervising pharmacist holds ultimate legal responsibility for the accuracy and appropriateness of the dispensed medication, including the final verification. This is why a pharmacist must check the technician's work before dispensing.
- Under the Poison Prevention Packaging Act, which professional or party may request that a prescription be dispensed in non-child-resistant packaging?
- Only the manufacturer
- Only the FDA
- The patient or the prescriber
- Only the wholesaler
Correct answer: The patient or the prescriber
Correct answer: The patient or the prescriber. The Poison Prevention Packaging Act allows a patient to request, or a prescriber to direct, that a medication be dispensed without child-resistant packaging, often for convenience or because of physical limitations. The prescriber may authorize this for a single prescription, while a patient may give a blanket waiver request.
- Sublingual nitroglycerin tablets are a noted exception to the Poison Prevention Packaging Act's child-resistant container requirement. What is the primary rationale for this exemption?
- The drug is non-toxic to children
- It is sold over the counter
- It is a controlled substance
- Patients need rapid, unimpeded access during an acute cardiac event
Correct answer: Patients need rapid, unimpeded access during an acute cardiac event
Correct answer: Patients need rapid, unimpeded access during an acute cardiac event. Sublingual nitroglycerin is exempt from child-resistant packaging because patients experiencing angina must be able to open the container quickly during a cardiac emergency. The exemption reflects a balance between child safety and the urgent therapeutic need for immediate access.
- Federal law requires the legend 'Rx only' on a prescription drug's manufacturer label. What does this legend indicate?
- The drug may be dispensed only on a valid prescription
- The drug is a controlled substance
- The drug is for veterinary use
- The drug is an investigational product
Correct answer: The drug may be dispensed only on a valid prescription
Correct answer: The drug may be dispensed only on a valid prescription. The 'Rx only' legend (formerly the federal legend statement) indicates that a drug is a prescription drug that may be dispensed only upon authorization from a licensed prescriber. It does not by itself indicate controlled substance status, which is shown separately by a schedule designation.
- Which federal program requires drug manufacturers to provide rebates and discounted pricing on outpatient drugs to eligible safety-net providers serving low-income populations?
- The Orphan Drug Program
- The 340B Drug Pricing Program
- REMS
- The DSCSA
Correct answer: The 340B Drug Pricing Program
Correct answer: The 340B Drug Pricing Program. The 340B Drug Pricing Program requires drug manufacturers participating in Medicaid to provide outpatient drugs at significantly reduced prices to eligible health care organizations (covered entities) that serve uninsured and low-income patients. It is distinct from safety programs like REMS and supply-chain laws like the DSCSA.
- Under the federal Controlled Substances Act, which entity assigns the actual schedule classification of a substance and may reschedule it?
- The pharmacy board alone
- The manufacturer
- The DEA, in coordination with the FDA/HHS
- The prescribing physician
Correct answer: The DEA, in coordination with the FDA/HHS
Correct answer: The DEA, in coordination with the FDA/HHS. The DEA, working with the FDA and the Department of Health and Human Services, determines and assigns the schedule classification of a controlled substance and may add, remove, or reschedule a substance based on its abuse potential and medical use. Individual pharmacies, manufacturers, and prescribers cannot change a drug's schedule.
- Under the Combat Methamphetamine Epidemic Act (CMEA), how long must a pharmacy retain the written or electronic logbook of pseudoephedrine sales after the date of the last entry?
- 2 years
- 6 months
- 5 years
- 10 years
Correct answer: 2 years
A retention period of 2 years is correct. The Combat Methamphetamine Epidemic Act (CMEA) requires pharmacies that sell scheduled listed chemical products containing pseudoephedrine, ephedrine, or phenylpropanolamine to keep the sales logbook for at least two years after the last entry. The logbook records the purchaser's name and address, product, quantity, date and time of sale, and the purchaser's signature, and these records must be available to enforcement officials.
- Which DEA form must a pharmacy complete to document the destruction (disposal) of unusable controlled substances from its inventory?
- DEA Form 222
- DEA Form 41
- DEA Form 106
- DEA Form 224
Correct answer: DEA Form 41
DEA Form 41 is correct. DEA Form 41 is the Registrant Record of Controlled Substances Destroyed, used to document the destruction of expired, damaged, or otherwise unusable controlled substances. DEA Form 222 is used to order Schedule II substances, Form 106 reports theft or significant loss, and Form 224 is the application for a pharmacy's DEA registration.
- Under the Omnibus Budget Reconciliation Act of 1990 (OBRA '90), what must a pharmacy do for Medicaid patients receiving new prescriptions?
- Provide mandatory counseling that the patient cannot decline
- Require the patient to sign a controlled-substance agreement
- Make an offer to counsel and conduct a prospective drug use review
- Report each prescription to the state board of pharmacy
Correct answer: Make an offer to counsel and conduct a prospective drug use review
The correct answer is that the pharmacy must make an offer to counsel the patient and conduct a prospective drug use review. OBRA '90 requires pharmacies to perform a prospective drug utilization review (screening for interactions, duplications, and other problems) and to offer counseling to Medicaid patients; many states extended these requirements to all patients. The offer to counsel is the standard, so the patient may decline it.
- Under federal law, when a Schedule II controlled substance is dispensed in an emergency on a prescriber's oral order, within how many days must the prescriber furnish a written, signed prescription to the pharmacy?
- 14 days
- 72 hours
- 24 hours
- 7 days
Correct answer: 7 days
7 days is correct. Federal law permits emergency oral prescribing of a Schedule II controlled substance limited to the amount needed for the emergency period, but the prescriber must deliver a written, signed prescription to the pharmacy within 7 days. If the prescription is not received, the pharmacist must notify the DEA. The 72-hour figure is a distractor associated with state partial-fill rules, not the emergency Schedule II requirement.
- Under the HIPAA Privacy Rule, what does the 'minimum necessary' standard require of a pharmacy technician?
- Give patients at least the minimum required counseling time
- Access or share only the minimum amount of protected health information needed to perform a task
- Have a minimum of two staff members verify each prescription
- Keep records for a minimum period set by federal law
Correct answer: Access or share only the minimum amount of protected health information needed to perform a task
The correct answer is to access or share only the minimum amount of protected health information (PHI) needed to perform a task. The HIPAA Privacy Rule's minimum necessary standard limits PHI use and disclosure to what is reasonably required for the intended purpose, so a technician should not access patient information beyond what the job task demands. The standard does not apply to disclosures made for treatment purposes between providers.
- Under federal regulations, a prescription for a Schedule III, IV, or V controlled substance is valid for refills for a maximum of how long after the date it was issued?
- 3 months
- 12 months
- 6 months
- 30 days
Correct answer: 6 months
6 months is correct. Federal law allows prescriptions for Schedule III, IV, and V controlled substances to be refilled up to five times within six months of the issue date, whichever limit is reached first. After six months or five refills, a new prescription is required. Schedule II prescriptions, by contrast, may not be refilled at all.
- According to ISMP, why should a trailing zero never be used after a whole number on a medication order (for example, writing '1.0 mg' instead of '1 mg')?
- It prevents the pharmacy software from accepting the order
- It violates federal labeling requirements for tablets
- If the decimal point is missed, the dose could be read as ten times the intended amount
- It makes the dose appear smaller than intended
Correct answer: If the decimal point is missed, the dose could be read as ten times the intended amount
Correct answer: If the decimal point is missed, the dose could be read as ten times the intended amount. ISMP lists trailing zeros as error-prone because '1.0 mg' can be misread as '10 mg' if the decimal point is overlooked, causing a tenfold overdose. The safe practice is to omit trailing zeros after a whole number.
- ISMP recommends always using a leading zero before a decimal expression of less than one (for example, '0.5 mg' rather than '.5 mg'). What is the primary safety reason?
- It is required by the DEA for controlled substances only
- A naked decimal point may be missed, causing the dose to be read as a tenfold overdose
- It standardizes the font size on the label
- It speeds up data entry in the pharmacy system
Correct answer: A naked decimal point may be missed, causing the dose to be read as a tenfold overdose
Correct answer: A naked decimal point may be missed, causing the dose to be read as a tenfold overdose. Without a leading zero, '.5 mg' can be misread as '5 mg' if the decimal is overlooked. Adding the leading zero ('0.5 mg') draws attention to the decimal and prevents a tenfold error.
- The abbreviation 'U' for units appears on the ISMP List of Error-Prone Abbreviations. What error is it most associated with?
- Being mistaken for the number zero, four, or 'cc', leading to overdoses
- Being read as a route of administration
- Being mistaken for milligrams
- Being confused with the patient's chart number
Correct answer: Being mistaken for the number zero, four, or 'cc', leading to overdoses
Correct answer: Being mistaken for the number zero, four, or 'cc', leading to overdoses. ISMP recommends writing out 'unit' because a handwritten 'U' can look like a 0 (making 4U read as 40) or a 4, dramatically overstating insulin and other unit-dosed drugs. The corrected practice is to spell out 'unit.'
- Why does the ISMP error-prone abbreviation list advise spelling out 'daily' instead of using 'QD', and 'every other day' instead of 'QOD'?
- They are Latin terms no longer recognized
- They imply intravenous administration
- QD and QOD can be mistaken for each other or for 'QID', changing the dosing frequency
- They are reserved for hospital use only
Correct answer: QD and QOD can be mistaken for each other or for 'QID', changing the dosing frequency
Correct answer: QD and QOD can be mistaken for each other or for 'QID', changing the dosing frequency. The period or tail of the 'Q' can make QD look like QOD or QID, altering how often a drug is given. Spelling out 'daily' and 'every other day' eliminates this ambiguity.
- The abbreviation 'MS' or 'MSO4' is flagged by ISMP because it can stand for two different drugs. Which two?
- Methotrexate and morphine sulfate
- Methadone and magnesium sulfate
- Morphine sulfate and methylprednisolone
- Morphine sulfate and magnesium sulfate
Correct answer: Morphine sulfate and magnesium sulfate
Correct answer: Morphine sulfate and magnesium sulfate. 'MS', 'MSO4', and 'MgSO4' are easily confused for one another, and these are very different drugs with very different effects. ISMP recommends writing the full drug names to prevent mix-ups.
- Under the NCC MERP medication-error index, how is a 'Category A' event classified?
- An error that resulted in the patient's death
- Circumstances or events that have the capacity to cause an error, but no error occurred
- An error that reached the patient and caused permanent harm
- An error requiring hospitalization
Correct answer: Circumstances or events that have the capacity to cause an error, but no error occurred
Correct answer: Circumstances or events that have the capacity to cause an error, but no error occurred. In the NCC MERP index, Category A represents a hazardous condition with the potential for error but where no actual error happened, making it the lowest severity tier on the scale.
- On the NCC MERP index, which category describes an error that occurred and reached the patient but did not cause harm?
- Category I
- Category C
- Category A
- Category G
Correct answer: Category C
Correct answer: Category C. In the NCC MERP severity index, Category C is an error that reached the patient but did not cause harm. Category A is a near-miss potential, while higher letters (G, H, I) denote permanent harm or death.
- MedWatch is a program operated by which agency for voluntary reporting of adverse events and product problems?
- The Institute for Safe Medication Practices (ISMP)
- The Food and Drug Administration (FDA)
- The Centers for Disease Control and Prevention (CDC)
- The Drug Enforcement Administration (DEA)
Correct answer: The Food and Drug Administration (FDA)
Correct answer: The Food and Drug Administration (FDA). MedWatch is the FDA's safety information and adverse event reporting program, used to report serious adverse events, product quality problems, and medication errors for FDA-regulated products.
- The ISMP National Medication Errors Reporting Program (ISMP MERP) primarily serves what function?
- It collects voluntarily reported errors and near misses to share lessons learned and prevention strategies
- It approves new drugs for market
- It licenses pharmacy technicians nationally
- It enforces fines against pharmacies that make errors
Correct answer: It collects voluntarily reported errors and near misses to share lessons learned and prevention strategies
Correct answer: It collects voluntarily reported errors and near misses to share lessons learned and prevention strategies. ISMP MERP is a confidential, voluntary national reporting program; the data drive alerts and best-practice recommendations rather than punitive enforcement.
- A Class I drug recall, as defined by the FDA, indicates which level of risk?
- A temporary or medically reversible adverse health consequence
- A minor labeling discrepancy only
- A situation with little likelihood of adverse health consequences
- A reasonable probability that use of the product will cause serious adverse health consequences or death
Correct answer: A reasonable probability that use of the product will cause serious adverse health consequences or death
Correct answer: A reasonable probability that use of the product will cause serious adverse health consequences or death. An FDA Class I recall is the most serious classification, reserved for products that could cause serious harm or death; Class II is reversible/temporary harm and Class III is unlikely to cause harm.
- When a Class II drug recall is issued, what does that classification mean?
- The product may cause death
- Use may cause temporary or medically reversible adverse health consequences, with a remote chance of serious harm
- The recall is voluntary and informational only
- The product poses no health risk
Correct answer: Use may cause temporary or medically reversible adverse health consequences, with a remote chance of serious harm
Correct answer: Use may cause temporary or medically reversible adverse health consequences, with a remote chance of serious harm. An FDA Class II recall sits between Class I (serious/death) and Class III (unlikely to cause harm), covering reversible effects with only a remote chance of serious consequences.
- A Risk Evaluation and Mitigation Strategy (REMS) is required by the FDA for certain drugs primarily to:
- Ensure that the benefits of a drug outweigh its serious risks
- Lower the wholesale cost of the drug
- Speed the drug's approval process
- Guarantee insurance coverage for the drug
Correct answer: Ensure that the benefits of a drug outweigh its serious risks
Correct answer: Ensure that the benefits of a drug outweigh its serious risks. A REMS is an FDA-required risk-management program (which may include medication guides, communication plans, or restricted distribution) used when extra safety measures are needed to keep a drug's benefits above its risks.
- A drug that carries a REMS with Elements to Assure Safe Use (ETASU) may require which of the following?
- That the drug be dispensed without a prescription
- Special prescriber certification, pharmacy enrollment, or documented safe-use conditions before dispensing
- That the drug be sold over the counter
- Only that the patient pays a higher copay
Correct answer: Special prescriber certification, pharmacy enrollment, or documented safe-use conditions before dispensing
Correct answer: Special prescriber certification, pharmacy enrollment, or documented safe-use conditions before dispensing. ETASU are the most restrictive REMS components and can mandate certified prescribers, enrolled/certified pharmacies, patient enrollment, or proof of safe-use conditions prior to dispensing.
- A Safety Data Sheet (SDS) must be readily accessible in the pharmacy primarily to provide information about:
- Patient adherence rates
- The hazards, safe handling, storage, and emergency procedures for a chemical or drug
- Insurance billing codes for hazardous drugs
- The retail price of each product
Correct answer: The hazards, safe handling, storage, and emergency procedures for a chemical or drug
Correct answer: The hazards, safe handling, storage, and emergency procedures for a chemical or drug. Under OSHA's Hazard Communication Standard, the SDS (formerly MSDS) gives staff details on physical/health hazards, protective measures, spill response, and first aid for hazardous substances.
- If a hazardous drug is spilled in the pharmacy, the first appropriate response using a chemotherapy spill kit is to:
- Mop the area with regular water and a paper towel
- Leave the spill and wait for the next shift
- Pour the spilled drug back into its original container
- Don appropriate PPE (such as chemo gloves and gown) and isolate the area before containing the spill
Correct answer: Don appropriate PPE (such as chemo gloves and gown) and isolate the area before containing the spill
Correct answer: Don appropriate PPE (such as chemo gloves and gown) and isolate the area before containing the spill. Hazardous-drug spill response begins with protecting the responder and restricting access, then containing and cleaning the spill with kit materials and disposing of waste appropriately.
- Used vials, gloves, and gowns contaminated with antineoplastic (chemotherapy) hazardous drug residue should be discarded into which container?
- Designated hazardous (chemotherapy) waste containers, typically yellow
- Red biohazard sharps containers only
- Regular trash
- The recycling bin
Correct answer: Designated hazardous (chemotherapy) waste containers, typically yellow
Correct answer: Designated hazardous (chemotherapy) waste containers, typically yellow. Trace chemotherapy waste must be segregated into specially labeled hazardous-waste containers (commonly yellow) to protect workers and meet environmental regulations, not placed in regular or ordinary biohazard trash.
- The 'five rights' of medication safety are most commonly listed as right patient, right drug, right dose, right route, and:
- Right insurance
- Right pharmacy
- Right manufacturer
- Right time
Correct answer: Right time
Correct answer: Right time. The classic five rights of medication administration are right patient, right drug, right dose, right route, and right time, providing a structured check that helps prevent medication errors at the point of dispensing or administration.
- During final verification, comparing the National Drug Code (NDC) number on the stock bottle to the NDC on the prescription label primarily helps prevent:
- Expired patient profiles
- Insurance rejections
- Incorrect store hours being printed
- Dispensing the wrong drug, strength, or dosage form
Correct answer: Dispensing the wrong drug, strength, or dosage form
Correct answer: Dispensing the wrong drug, strength, or dosage form. The NDC uniquely identifies the manufacturer, product, and package size, so matching the NDC on the source bottle to the filled label is a key safety check against selecting the wrong product or strength.
- A prospective drug utilization review (DUR) performed before dispensing is designed primarily to detect:
- The expiration date of the store license
- Potential drug interactions, duplications, allergies, or dosing problems
- The pharmacy's daily prescription volume
- Whether the patient paid the copay
Correct answer: Potential drug interactions, duplications, allergies, or dosing problems
Correct answer: Potential drug interactions, duplications, allergies, or dosing problems. A prospective DUR screens a new order against the patient's profile before the drug is dispensed, flagging interactions, therapeutic duplications, allergies, contraindications, and inappropriate dosing to protect patient safety.
- Storing concentrated electrolytes and other high-alert medications using auxiliary warning labels and physical separation is an example of which safety strategy?
- Benchmarking
- Increasing inventory turnover
- Adding constraints and reminders to reduce the chance of error
- Outsourcing dispensing
Correct answer: Adding constraints and reminders to reduce the chance of error
Correct answer: Adding constraints and reminders to reduce the chance of error. Warning labels and physical separation are forcing functions/constraints layered into the medication-use process so that a high-alert product is harder to select or administer incorrectly, reducing the likelihood and severity of errors.
- Independent double-checks for high-alert medications such as insulin or heparin are most effective when:
- The same technician checks the order twice
- One person checks the work and then asks the other to agree quickly
- The check is skipped to save time during busy periods
- Two qualified individuals separately verify the medication without influencing each other
Correct answer: Two qualified individuals separately verify the medication without influencing each other
Correct answer: Two qualified individuals separately verify the medication without influencing each other. A true independent double-check has each person review the product, dose, and calculation on their own before comparing results, which catches errors a single or collaborative check would miss.
- Cold-chain medications such as many vaccines must typically be stored in a refrigerator at which temperature range?
- -25 to -10 degrees Celsius
- 15 to 25 degrees Celsius
- 2 to 8 degrees Celsius
- 30 to 40 degrees Celsius
Correct answer: 2 to 8 degrees Celsius
Correct answer: 2 to 8 degrees Celsius. USP-defined refrigerated storage is 2 to 8 degrees Celsius (about 36 to 46 degrees Fahrenheit). Maintaining this cold-chain range preserves potency and protects patients from receiving ineffective refrigerated products such as vaccines and insulin.
- USP defines 'controlled room temperature' for medication storage as approximately:
- 20 to 25 degrees Celsius (with allowable excursions)
- 30 to 40 degrees Celsius
- -20 degrees Celsius
- 2 to 8 degrees Celsius
Correct answer: 20 to 25 degrees Celsius (with allowable excursions)
Correct answer: 20 to 25 degrees Celsius (with allowable excursions). USP controlled room temperature is defined as 20 to 25 degrees Celsius (68 to 77 degrees Fahrenheit), with permitted brief excursions. Storing drugs within this range maintains stability and prevents potency loss that could harm patients.
- A pharmacy uses temperature-logging and continuous monitoring of its drug refrigerator primarily to ensure:
- That stored medications remain within safe, effective temperature ranges
- That inventory counts match the schedule
- That the electric bill is minimized
- That billing is accurate
Correct answer: That stored medications remain within safe, effective temperature ranges
Correct answer: That stored medications remain within safe, effective temperature ranges. Continuous temperature monitoring and logging detect excursions promptly so compromised drugs can be quarantined, protecting patients from receiving products that may have lost potency or become unsafe.
- Under USP <797>, a primary engineering control (PEC) such as a laminar airflow workbench provides what level of air quality at the direct compounding area?
- ISO Class 8
- Unclassified room air
- ISO Class 5
- ISO Class 7
Correct answer: ISO Class 5
Correct answer: ISO Class 5. A primary engineering control (such as a laminar airflow workbench or biological safety cabinet) provides an ISO Class 5 environment at the critical compounding site, the cleanest air classification required to protect sterile preparations from contamination.
- When compounding a hazardous sterile drug under USP <800>, which type of primary engineering control is appropriate to protect both the product and the worker?
- An open countertop
- A standard fume-free clean bench
- A Class II biological safety cabinet or compounding aseptic containment isolator
- A horizontal laminar airflow workbench
Correct answer: A Class II biological safety cabinet or compounding aseptic containment isolator
Correct answer: A Class II biological safety cabinet or compounding aseptic containment isolator. For hazardous sterile compounding, USP <800> requires a containment primary engineering control such as a Class II BSC or CACI, which provides both ISO Class 5 air for the product and inward airflow/containment to protect personnel.
- During aseptic technique, in what general order should garbing be performed to maintain a clean-to-dirty progression?
- Sterile gloves first, then shoe covers and mask
- Gown first, then enter the cleanroom, then wash hands
- From dirtiest activities to cleanest: shoe covers/hair cover/mask, then hand hygiene, then gown, then sterile gloves
- Order does not matter as long as all items are worn
Correct answer: From dirtiest activities to cleanest: shoe covers/hair cover/mask, then hand hygiene, then gown, then sterile gloves
Correct answer: From dirtiest activities to cleanest: shoe covers/hair cover/mask, then hand hygiene, then gown, then sterile gloves. USP <797> garbing follows a dirtiest-to-cleanest sequence so that the most contaminated items are donned first and sterile gloves last, minimizing introduction of contaminants into the compounding area.
- Disinfecting the rubber stopper of a vial with sterile 70% isopropyl alcohol before needle entry primarily serves to:
- Reduce surface microbial contamination of the critical site
- Extend the manufacturer expiration date
- Dissolve the drug faster
- Improve the vial's appearance
Correct answer: Reduce surface microbial contamination of the critical site
Correct answer: Reduce surface microbial contamination of the critical site. Swabbing the vial septum with sterile 70% IPA and allowing it to dry disinfects the critical entry site, lowering the risk of introducing microorganisms into a sterile preparation and protecting the patient from infection.
- In a horizontal laminar airflow workbench, why must a technician avoid placing objects between the HEPA filter and the sterile product (avoiding 'shadowing')?
- It blocks the technician's view of the label
- It increases the drug's expiration date
- It makes the hood louder
- It disrupts the first-air, allowing contamination to reach the critical site
Correct answer: It disrupts the first-air, allowing contamination to reach the critical site
Correct answer: It disrupts the first-air, allowing contamination to reach the critical site. Objects placed upstream interrupt the unidirectional 'first air' coming directly from the HEPA filter, creating turbulence and shadowing that can carry contaminants onto critical sites, compromising the sterility of the preparation.
- Hand hygiene before compounding and dispensing is emphasized in pharmacy safety primarily because it:
- Reduces transmission of microorganisms that could contaminate products or harm patients
- Replaces the need for gloves entirely
- Is required only for controlled substances
- Speeds up the workflow
Correct answer: Reduces transmission of microorganisms that could contaminate products or harm patients
Correct answer: Reduces transmission of microorganisms that could contaminate products or harm patients. Proper hand hygiene is a foundational infection-control measure that lowers the microbial bioburden on staff hands, reducing contamination of preparations and the spread of pathogens in the pharmacy.
- A continuous quality improvement (CQI) program in a pharmacy is best characterized by:
- An ongoing, systematic effort to analyze processes and reduce errors over time
- A one-time inspection performed annually
- Only correcting errors that patients complain about
- Punishing individual staff after each error
Correct answer: An ongoing, systematic effort to analyze processes and reduce errors over time
Correct answer: An ongoing, systematic effort to analyze processes and reduce errors over time. CQI is a continuous, data-driven approach that examines workflow and outcomes to identify improvement opportunities and reduce errors, rather than a punitive or one-time activity.
- The Plan-Do-Study-Act (PDSA) cycle is used in pharmacy quality improvement to:
- Calculate insurance reimbursement
- Test and refine a change on a small scale before broader implementation
- Schedule employee shifts
- Track controlled-substance inventory
Correct answer: Test and refine a change on a small scale before broader implementation
Correct answer: Test and refine a change on a small scale before broader implementation. PDSA is an iterative improvement method: plan a change, do (try) it on a small scale, study the results, and act to adopt, adapt, or abandon it, allowing safe testing before wide rollout.
- A 'sentinel event' in patient safety is best described as:
- An unexpected occurrence involving death or serious physical or psychological injury, or the risk thereof
- A routine prescription transfer
- A minor typo on a label corrected before dispensing
- A scheduled inventory audit
Correct answer: An unexpected occurrence involving death or serious physical or psychological injury, or the risk thereof
Correct answer: An unexpected occurrence involving death or serious physical or psychological injury, or the risk thereof. A sentinel event is a serious, unexpected safety event signaling the need for immediate investigation (such as a root cause analysis) and response to prevent recurrence.
- An adverse drug event (ADE) differs from an adverse drug reaction (ADR) in that an ADE:
- Is always caused by an allergy
- Only occurs with over-the-counter products
- Cannot be prevented
- Includes harm from medication errors and misuse, not just inherent drug reactions
Correct answer: Includes harm from medication errors and misuse, not just inherent drug reactions
Correct answer: Includes harm from medication errors and misuse, not just inherent drug reactions. An ADE is any harm associated with medication use, encompassing preventable causes such as errors and misuse, whereas an ADR specifically refers to harm from the drug itself at normal doses; many ADEs are therefore preventable.
- Why does ISMP recommend writing out 'microgram' or using 'mcg' instead of the Greek letter abbreviation for micrograms?
- It cannot be entered into the computer
- It is shorter to write
- The symbol can be misread as 'mg' (milligrams), causing a 1000-fold dosing error
- It is required only in veterinary pharmacy
Correct answer: The symbol can be misread as 'mg' (milligrams), causing a 1000-fold dosing error
Correct answer: The symbol can be misread as 'mg' (milligrams), causing a 1000-fold dosing error. The micro symbol can be mistaken for 'mg', and since a milligram is 1000 micrograms, the mix-up could cause a thousandfold overdose. ISMP advises using 'mcg' to eliminate this risk.
- Smart infusion pumps with dose-error reduction software improve safety primarily by:
- Automatically billing the patient
- Reducing the cost of IV fluids
- Eliminating the need for a prescription
- Alerting staff when a programmed dose falls outside preset safe limits
Correct answer: Alerting staff when a programmed dose falls outside preset safe limits
Correct answer: Alerting staff when a programmed dose falls outside preset safe limits. Smart pumps contain drug libraries with hard and soft limits, and dose-error reduction software warns or blocks programming that exceeds safe parameters, helping intercept IV medication errors before they reach the patient.
- Performing a physical inventory and routinely checking shelves for expired products on the shelf supports patient safety by:
- Reducing the pharmacy's tax burden
- Preventing dispensing of expired, degraded, or sub-potent medications
- Speeding insurance adjudication
- Increasing the number of brand-name drugs stocked
Correct answer: Preventing dispensing of expired, degraded, or sub-potent medications
Correct answer: Preventing dispensing of expired, degraded, or sub-potent medications. Regularly identifying and removing outdated stock ensures patients receive medications that are still potent and safe, since expired products may have reduced effectiveness or altered stability.
- When a manufacturer recall notice is received, the pharmacy's appropriate first step for patient safety is to:
- Discard all unrelated inventory
- Ignore the notice if no complaints have been received
- Identify and quarantine the affected lot numbers so they are not dispensed
- Continue dispensing the product until it sells out
Correct answer: Identify and quarantine the affected lot numbers so they are not dispensed
Correct answer: Identify and quarantine the affected lot numbers so they are not dispensed. The pharmacy must check stock against the recall's specific lot/NDC information, remove and segregate (quarantine) affected product to prevent dispensing, and follow the recall instructions for return or disposal.
- Reporting a 'near miss' (an error caught before reaching the patient) is encouraged in a strong safety culture because it:
- Increases the pharmacy's prescription count
- Identifies which employee to terminate
- Reveals system weaknesses so corrections can prevent future actual errors
- Is required only when a patient is harmed
Correct answer: Reveals system weaknesses so corrections can prevent future actual errors
Correct answer: Reveals system weaknesses so corrections can prevent future actual errors. Near-miss reporting surfaces latent process flaws before they cause harm, allowing proactive system fixes; a non-punitive culture encourages staff to report these valuable warning signs.
- Counseling and using the 'teach-back' method with a patient at the point of sale primarily improves safety by:
- Confirming the patient understands how to take the medication correctly
- Reducing the pharmacy's workload
- Increasing the price of the prescription
- Replacing the need for a label
Correct answer: Confirming the patient understands how to take the medication correctly
Correct answer: Confirming the patient understands how to take the medication correctly. With teach-back, the patient restates the directions in their own words, letting staff verify comprehension and correct misunderstandings, which reduces administration errors and improves safe, effective use at home.
- Tracking and trending reported medication errors over time is valuable for quality assurance because it:
- Eliminates the need for double-checks
- Identifies a single guilty employee
- Reveals patterns and recurring causes that targeted system changes can address
- Guarantees no future errors
Correct answer: Reveals patterns and recurring causes that targeted system changes can address
Correct answer: Reveals patterns and recurring causes that targeted system changes can address. Aggregating and trending error data exposes systemic patterns (such as a recurring LASA mix-up), enabling focused interventions and measuring whether improvements actually reduce errors over time.
- Within a 'Just Culture' framework, an employee who makes an honest slip while following proper procedures should generally be:
- Disciplined harshly to deter others
- Reported to law enforcement
- Immediately terminated
- Consoled and supported, with focus placed on fixing the system
Correct answer: Consoled and supported, with focus placed on fixing the system
Correct answer: Consoled and supported, with focus placed on fixing the system. Just Culture distinguishes human error (console and fix the system) from at-risk behavior (coach) and reckless behavior (discipline). An honest slip is treated as human error, encouraging reporting and system improvement rather than blame.
- Verifying a patient's allergy information and updating the patient profile before dispensing is a safety step that primarily prevents:
- Insurance fraud
- Dispensing a drug to which the patient has a documented allergy or cross-sensitivity
- Pricing errors
- Inventory shortages
Correct answer: Dispensing a drug to which the patient has a documented allergy or cross-sensitivity
Correct answer: Dispensing a drug to which the patient has a documented allergy or cross-sensitivity. Confirming and maintaining accurate allergy data lets the system and staff flag drugs the patient cannot safely take, preventing potentially serious allergic or cross-reactive adverse events.
- Closed-system drug-transfer devices (CSTDs) are used with hazardous drugs primarily to:
- Increase the drug's shelf life
- Mechanically prohibit the escape of hazardous drug or vapor and protect personnel from exposure
- Reduce the cost of compounding
- Speed up the compounding process
Correct answer: Mechanically prohibit the escape of hazardous drug or vapor and protect personnel from exposure
Correct answer: Mechanically prohibit the escape of hazardous drug or vapor and protect personnel from exposure. A CSTD prevents the transfer of environmental contaminants into the system and the escape of hazardous drug or vapor out of the system, reducing occupational exposure during hazardous-drug compounding and administration as emphasized by USP <800>.
- Why should a pharmacy avoid storing different strengths of the same medication directly next to each other on the shelf?
- It violates copyright on the labels
- It looks disorganized to customers
- It slows down inventory counts
- It increases the risk of selecting the wrong strength during filling
Correct answer: It increases the risk of selecting the wrong strength during filling
Correct answer: It increases the risk of selecting the wrong strength during filling. Adjacent placement of similar-looking different strengths invites selection errors; separating them, adding shelf alerts, or using tall man lettering reduces the chance of grabbing the wrong product during dispensing.
- Scanning the product barcode against the prescription during the fill process is a safety technology that primarily verifies:
- That the correct drug and strength have been selected for the order
- The pharmacist's license number
- The patient's insurance eligibility
- The store's hours of operation
Correct answer: That the correct drug and strength have been selected for the order
Correct answer: That the correct drug and strength have been selected for the order. Barcode scanning electronically confirms the NDC of the selected stock matches what the order requires, intercepting wrong-drug and wrong-strength selection errors before the product reaches the verification or patient stage.
- According to ISMP and The Joint Commission, which of the following is on the official list of error-prone abbreviations that should never be used because it is frequently mistaken for another term?
- U for unit
- Mg for milligram
- mL for milliliter
- Kg for kilogram
Correct answer: U for unit
Correct answer: U for unit. The abbreviation 'U' appears on the ISMP List of Error-Prone Abbreviations and The Joint Commission 'Do Not Use' list because a handwritten 'U' is easily mistaken for a zero, a four, or 'cc', which can cause a dangerous overdose; the word 'unit' must be spelled out. By contrast, mg, mL, and kg are standard accepted metric abbreviations that are not on the do-not-use list.
- To prevent a tenfold dosing error, ISMP recommends a specific rule regarding zeros in numeric doses. Which practice should be followed?
- Use a trailing zero after a whole number, such as 5.0 mg
- Use a leading zero before a decimal point for doses less than one, such as 0.5 mg
- Omit the leading zero for doses less than one, such as .5 mg
- Always express doses as fractions rather than decimals
Correct answer: Use a leading zero before a decimal point for doses less than one, such as 0.5 mg
Correct answer: Use a leading zero before a decimal point for doses less than one, such as 0.5 mg. A leading zero ensures the decimal point is not missed, preventing a tenfold overdose (reading .5 as 5). Conversely, a trailing zero (5.0 mg) is prohibited because if the decimal is overlooked the dose appears as 50 mg, also causing a tenfold error.
- The 'Swiss cheese model' is frequently cited in pharmacy patient-safety training. What does this model illustrate about how medication errors reach the patient?
- A single individual is almost always to blame for an error
- Errors occur only when equipment fails rather than when people fail
- An error reaches the patient when gaps in multiple successive safeguards happen to line up
- Errors can be completely eliminated by adding enough rules
Correct answer: An error reaches the patient when gaps in multiple successive safeguards happen to line up
Correct answer: An error reaches the patient when gaps in multiple successive safeguards happen to line up. The Swiss cheese model depicts layered defenses as slices of cheese, each with holes (weaknesses); harm reaches the patient only when the holes in successive layers align, allowing the error to pass through every barrier. It emphasizes system-based failures rather than blaming one person, and recognizes that no single layer is perfect.
- Under The Joint Commission's definitions, a 'sentinel event' is best described as:
- Any prescribing error caught before the drug leaves the pharmacy
- A routine inventory discrepancy discovered during a cycle count
- A documented allergy that was correctly avoided
- A patient-safety event that results in death, permanent harm, or severe temporary harm requiring intervention to sustain life
Correct answer: A patient-safety event that results in death, permanent harm, or severe temporary harm requiring intervention to sustain life
Correct answer: A patient-safety event that results in death, permanent harm, or severe temporary harm requiring intervention to sustain life. The Joint Commission defines a sentinel event as a serious, often unexpected event signaling the need for immediate investigation and response; it is unrelated to the natural course of the patient's illness. An intercepted error, an inventory discrepancy, or a correctly avoided allergy do not meet this severe-harm threshold.
- Which federal entity publishes the list of antineoplastic and other hazardous drugs that pharmacies use to determine special handling requirements?
- The National Institute for Occupational Safety and Health (NIOSH)
- The Drug Enforcement Administration (DEA)
- The Federal Trade Commission (FTC)
- The Centers for Medicare and Medicaid Services (CMS)
Correct answer: The National Institute for Occupational Safety and Health (NIOSH)
Correct answer: The National Institute for Occupational Safety and Health (NIOSH). NIOSH maintains the periodically updated list of hazardous drugs that USP General Chapter <800> references for safe handling; pharmacies use it to identify which products require special containment, PPE, and storage. The DEA regulates controlled substances, the FTC handles trade practices, and CMS administers Medicare and Medicaid reimbursement.
- A pharmacy preparing a high-alert intravenous medication requires that a second qualified staff member verify the drug, concentration, and pump settings before administration. This safeguard is known as:
- A formulary substitution
- An independent double check
- A prospective utilization review
- A therapeutic interchange
Correct answer: An independent double check
Correct answer: An independent double check. An independent double check has a second qualified person separately verify a high-alert preparation without being influenced by the first person's work, catching errors before they reach the patient. A formulary substitution and therapeutic interchange involve switching products, and a prospective utilization review evaluates appropriateness of therapy rather than verifying a single preparation.
- The MedWatch program is the primary mechanism for reporting which type of safety information to the FDA?
- Controlled substance theft and loss
- Pharmacy licensure renewals
- Suspected adverse events and product quality problems with drugs and medical devices
- Insurance reimbursement disputes
Correct answer: Suspected adverse events and product quality problems with drugs and medical devices
Correct answer: Suspected adverse events and product quality problems with drugs and medical devices. MedWatch is the FDA's voluntary safety reporting system used to report serious adverse reactions, product defects, and quality problems so the agency can monitor postmarket safety. Controlled substance losses are reported to the DEA on Form 106, licensure is handled by state boards, and reimbursement disputes are not safety reports.
- When a drug recall is announced, what is the most appropriate immediate action for pharmacy staff regarding the affected stock on the shelf?
- Dispense remaining stock quickly before it expires
- Repackage the product into unit-dose containers
- Leave the product on the shelf until the manufacturer arrives
- Physically segregate and quarantine the product so it cannot be dispensed
Correct answer: Physically segregate and quarantine the product so it cannot be dispensed
Correct answer: Physically segregate and quarantine the product so it cannot be dispensed. Recalled stock must be removed from active inventory and quarantined in a clearly marked, separate area to prevent accidental dispensing while it awaits return or destruction. Continuing to dispense, repackaging, or leaving the recalled product accessible all risk patient harm and violate recall procedures.
- To maintain the cold chain and ensure product integrity, refrigerated pharmacy medications should generally be stored within which temperature range?
- 2 to 8 degrees Celsius (36 to 46 degrees Fahrenheit)
- Minus 20 to minus 10 degrees Celsius
- 15 to 30 degrees Celsius
- 30 to 40 degrees Celsius
Correct answer: 2 to 8 degrees Celsius (36 to 46 degrees Fahrenheit)
Correct answer: 2 to 8 degrees Celsius (36 to 46 degrees Fahrenheit). USP-defined refrigerated storage is 2 to 8 degrees Celsius, and pharmacies must log and monitor refrigerator temperatures to keep heat-sensitive products such as many vaccines and insulins within this range. The minus 20 range is freezer storage, and the 15 to 30 degree range is controlled room temperature, not refrigeration.
- When entering a sterile compounding cleanroom, hand hygiene and garbing must be performed in a specific order. Which sequence best reflects USP <797> practice?
- Don sterile gloves first, then wash hands and put on the gown
- Remove visible jewelry, don gown and other garb in the anteroom, then perform hand hygiene and don sterile gloves last inside the buffer area
- Put on the gown, gloves, and mask before removing any jewelry
- Apply alcohol-based gloves before donning shoe covers
Correct answer: Remove visible jewelry, don gown and other garb in the anteroom, then perform hand hygiene and don sterile gloves last inside the buffer area
Correct answer: Remove visible jewelry, don gown and other garb in the anteroom, then perform hand hygiene and don sterile gloves last inside the buffer area. Garbing proceeds from dirtiest to cleanest activity, with sterile gloves applied last after hand antisepsis so the gloves are not contaminated during dressing. Donning gloves first or before hand hygiene defeats the purpose and is not permitted.
- A pharmacy keeps a spill kit readily available primarily for which patient- and worker-safety purpose?
- To repackage bulk medications into unit doses
- To calibrate the balance used in nonsterile compounding
- To safely contain and clean up hazardous drug spills and protect personnel from exposure
- To document controlled substance inventory
Correct answer: To safely contain and clean up hazardous drug spills and protect personnel from exposure
Correct answer: To safely contain and clean up hazardous drug spills and protect personnel from exposure. A spill kit contains PPE and absorbent and containment materials so staff can manage hazardous drug spills without being exposed to toxic substances, consistent with USP <800> requirements. Repackaging, balance calibration, and controlled substance documentation are unrelated functions.
- Under the NCC MERP index used to categorize medication errors, which of the following describes a Category A event?
- An error that reached the patient and caused permanent harm
- An error that contributed to or resulted in the patient's death
- An error requiring hospitalization to treat the harm
- Circumstances or events that have the capacity to cause error, but no error has yet occurred
Correct answer: Circumstances or events that have the capacity to cause error, but no error has yet occurred
Correct answer: Circumstances or events that have the capacity to cause error, but no error has yet occurred. In the National Coordinating Council for Medication Error Reporting and Prevention index, Category A is the lowest level, describing hazardous conditions with the potential to cause an error before any error happens. The higher categories describe errors that reach the patient and progressively more serious harm, up to death at Category I.
- Barcode verification scanning during the dispensing process most directly reduces which type of error?
- Selecting the wrong drug product or strength from the shelf
- Incorrectly calculating an insurance copay
- Failing to counsel the patient
- Storing a medication at the wrong temperature
Correct answer: Selecting the wrong drug product or strength from the shelf
Correct answer: Selecting the wrong drug product or strength from the shelf. Barcode scanning at the point of dispensing matches the National Drug Code of the product in hand against the order, catching wrong-drug and wrong-strength selection errors before the prescription is filled. It does not address copay calculation, patient counseling, or storage temperature, which are governed by other processes.
- Many institutions program 'smart' infusion pumps with dose error reduction software (DERS). The chief safety benefit of these built-in dose limits is that they:
- Eliminate the need for any pharmacist verification
- Alert the user when a programmed dose or rate falls outside preset safe limits, helping prevent IV overdoses
- Automatically bill the patient's insurance
- Replace the need to label IV bags
Correct answer: Alert the user when a programmed dose or rate falls outside preset safe limits, helping prevent IV overdoses
Correct answer: Alert the user when a programmed dose or rate falls outside preset safe limits, helping prevent IV overdoses. Smart pumps use drug libraries with soft and hard dose limits, so when a clinician enters a dose or rate outside the safe range the pump warns or stops, intercepting potentially fatal IV errors. They do not eliminate pharmacist verification, handle billing, or remove labeling requirements.
- A prospective drug utilization review (DUR) performed before dispensing primarily protects patient safety by:
- Auditing past claims for fraud after dispensing
- Counting controlled substance inventory at month end
- Screening for drug interactions, duplications, allergies, and dosing problems before the medication is given
- Negotiating drug prices with wholesalers
Correct answer: Screening for drug interactions, duplications, allergies, and dosing problems before the medication is given
Correct answer: Screening for drug interactions, duplications, allergies, and dosing problems before the medication is given. A prospective DUR evaluates the prescription against the patient's profile in real time, flagging interactions, therapeutic duplication, allergies, and inappropriate doses so problems are resolved before dispensing. Retrospective claim audits, inventory counts, and price negotiation are separate activities that do not screen therapy before it reaches the patient.
- A pharmacy technician notices a computerized alert warning of a serious drug interaction and the pharmacist must decide whether to override it. To preserve patient safety, override functions should be:
- Disabled entirely so no alert can ever be bypassed
- Used routinely to keep workflow moving quickly
- Performed only by pharmacy technicians
- Documented with the reason and limited to clinically appropriate situations to avoid alert fatigue while preventing inappropriate bypassing
Correct answer: Documented with the reason and limited to clinically appropriate situations to avoid alert fatigue while preventing inappropriate bypassing
Correct answer: Documented with the reason and limited to clinically appropriate situations to avoid alert fatigue while preventing inappropriate bypassing. Safe override practice records why an alert was bypassed and reserves overrides for genuinely appropriate clinical cases, balancing the danger of alert fatigue against the danger of ignoring real warnings. Disabling alerts removes protection, routine overriding undermines the safeguard, and the pharmacist, not the technician, makes the clinical override decision.
- The 'five rights' of medication use are a foundational safety check. Which of the following is one of the traditional five rights?
- Right route of administration
- Right insurance plan
- Right manufacturer
- Right copay amount
Correct answer: Right route of administration
Correct answer: Right route of administration. The traditional five rights are the right patient, right drug, right dose, right route, and right time, and verifying the route helps ensure a medication is given by the intended method. Insurance plan, manufacturer, and copay are administrative or financial details, not part of the clinical five rights safety check.
- Continuous quality improvement (CQI) programs in pharmacy commonly use the PDSA cycle. The letters PDSA stand for:
- Prepare, Dispense, Stock, Audit
- Plan, Do, Study, Act
- Prescribe, Deliver, Sign, Approve
- Process, Document, Submit, Archive
Correct answer: Plan, Do, Study, Act
Correct answer: Plan, Do, Study, Act. The PDSA cycle is an iterative quality-improvement method in which teams Plan a change, Do (implement it on a small scale), Study the results, and Act to adopt, adjust, or abandon the change. The other expansions are fabricated and do not represent the recognized continuous quality improvement framework.
- Why does ISMP recommend that the trailing zero be eliminated when expressing a whole-number dose (for example, writing '5 mg' rather than '5.0 mg')?
- It makes the label easier to print
- Trailing zeros are required only for liquids
- If the decimal point is missed, '5.0' could be read as '50', causing a tenfold overdose
- It allows the dose to be billed at a higher rate
Correct answer: If the decimal point is missed, '5.0' could be read as '50', causing a tenfold overdose
Correct answer: If the decimal point is missed, '5.0' could be read as '50', causing a tenfold overdose. A trailing zero adds no value to a whole number and creates a serious hazard because an overlooked decimal point turns 5.0 mg into 50 mg. Eliminating the trailing zero removes that risk; the practice is a safety measure, not a printing, formatting, or billing convenience.
- Within a sterile compounding facility, the primary engineering control (PEC), such as a laminar airflow workbench or biological safety cabinet, contributes to patient safety mainly by:
- Heating the compounding ingredients to sterilize them
- Automatically labeling the finished product
- Recording the beyond-use date in the computer system
- Providing an ISO Class 5 environment that minimizes airborne contamination of the compounded sterile preparation
Correct answer: Providing an ISO Class 5 environment that minimizes airborne contamination of the compounded sterile preparation
Correct answer: Providing an ISO Class 5 environment that minimizes airborne contamination of the compounded sterile preparation. A primary engineering control supplies the critical ISO Class 5 air (the direct compounding area) where sterile products are prepared, reducing the risk of microbial and particulate contamination that could harm patients. It does not sterilize ingredients with heat, generate labels, or record beyond-use dates.
- A sig reads 'ii tabs PO bid x 10 days.' How many tablets should be dispensed to complete the full course?
- 20 tablets
- 40 tablets
- 10 tablets
- 30 tablets
Correct answer: 40 tablets
The correct answer is 40 tablets. The sig directs 2 tablets twice daily, which is 4 tablets per day; over 10 days that totals 4×10=40 tablets.
- A prescription is written for amoxicillin 250 mg/5 mL, 1 teaspoonful PO tid for 10 days. What total volume should be dispensed?
Correct answer: 150 mL
The correct answer is 150 mL. One teaspoonful equals 5 mL, given three times daily equals 15 mL/day; over 10 days that is 15×10=150 mL.
- When entering a new prescription, a technician notices the prescriber wrote 'QD' for the dosing frequency. Why is this abbreviation on the ISMP error-prone list?
- It can be mistaken for 'every other day'
- It indicates an unapproved route
- It can be mistaken for 'four times daily' or 'OD' (right eye)
- It is only valid for controlled substances
Correct answer: It can be mistaken for 'four times daily' or 'OD' (right eye)
The correct answer is that QD can be mistaken for 'four times daily' (qid) or 'OD' (right eye). ISMP recommends writing out 'daily' to prevent misinterpretation of the period or tail of the Q.
- A prescriber writes a dose as '.5 mg.' According to ISMP safe practices, why should this be flagged during order entry?
- A naked decimal point can be missed, causing a tenfold overdose
- Doses must always be in micrograms
- Leading zeros are prohibited on labels
- The unit should be expressed as a ratio
Correct answer: A naked decimal point can be missed, causing a tenfold overdose
The correct answer is that a naked decimal point can be missed, causing a tenfold overdose. ISMP requires a leading zero before a decimal (0.5 mg) so the dose is not read as 5 mg.
- A prescription reads 'Lasix 40 mg, i tab PO daily.' During entry, which entry is the correct generic name to verify against the brand?
- Furosemide
- Finasteride
- Fluoxetine
- Famotidine
Correct answer: Furosemide
The correct answer is furosemide, the generic name for Lasix. Verifying the brand-to-generic match during order entry prevents dispensing the wrong drug.
- A sig reads '1 supp PR hs.' How should the route and timing be translated for the label?
- Take 1 tablet by mouth half-strength
- Place 1 suppository under the tongue every hour
- Insert 1 suppository vaginally in the morning
- Insert 1 suppository rectally at bedtime
Correct answer: Insert 1 suppository rectally at bedtime
The correct answer is insert 1 suppository rectally at bedtime. 'PR' means per rectum and 'hs' (hora somni) means at bedtime.
- A maintenance medication is written 'metoprolol 50 mg, 1 tab PO q12h, dispense 30-day supply.' How many tablets equal a 30-day supply?
- 60 tablets
- 30 tablets
- 90 tablets
- 45 tablets
Correct answer: 60 tablets
The correct answer is 60 tablets. One tablet every 12 hours equals 2 tablets per day; over 30 days that is 2×30=60 tablets.
- When processing a third-party insurance claim, a 'rejection' returns the code 'refill too soon.' What does this typically indicate?
- The patient still has medication remaining based on the last fill date
- The drug is not on the formulary
- The prescriber DEA number is invalid
- The quantity exceeds the day supply maximum
Correct answer: The patient still has medication remaining based on the last fill date
The correct answer is that the patient still has medication remaining based on the last fill date. A 'refill too soon' rejection means the previous supply has not been exhausted under the plan's day-supply calculation.
- During adjudication, a claim rejects with 'NDC not covered.' What is an appropriate next step for the technician?
- Dispense the medication without billing
- Check for a covered alternative NDC or therapeutic equivalent on the formulary
- Increase the quantity dispensed
- Change the patient's date of birth
Correct answer: Check for a covered alternative NDC or therapeutic equivalent on the formulary
The correct answer is to check for a covered alternative NDC or therapeutic equivalent on the formulary. The plan does not cover that specific product, so a covered alternative or prior authorization may be needed.
- A claim is rejected for 'prior authorization required.' What does this mean for processing the prescription?
- The prescriber must obtain approval from the plan before it will pay
- The drug can never be dispensed
- The patient must pay cash and cannot be reimbursed
- The pharmacy must reduce the quantity
Correct answer: The prescriber must obtain approval from the plan before it will pay
The correct answer is that the prescriber must obtain approval from the plan before it will pay. Prior authorization requires the prescriber to justify medical necessity to the insurer before the claim is covered.
- The 'DAW' field is set to code 1 on a processed claim. What does DAW 1 indicate?
- Substitution is allowed
- No product selection indicated
- The patient requested the generic
- The prescriber requires the brand-name product (dispense as written)
Correct answer: The prescriber requires the brand-name product (dispense as written)
The correct answer is that the prescriber requires the brand-name product (dispense as written). DAW 1 is a prescriber-mandated brand, and the system must bill and dispense the brand accordingly.
- On a processed insurance claim, the amount the patient owes at the counter is best described as the:
- Average wholesale price
- Maximum allowable cost
- Copay or cost-share
- Usual and customary charge
Correct answer: Copay or cost-share
The correct answer is the copay or cost-share. After adjudication, the copay is the portion of the cost the patient is responsible for paying at pickup.
- A prescription quantity is written as 'disp #30, refills x5.' How many total dispensing events (including the original fill) does this authorize?
Correct answer: 6
The correct answer is 6. The original fill plus 5 authorized refills equals 6 total dispensing events.
- While entering a prescription, the technician must determine the days' supply for an inhaler delivering 200 metered doses, used as '2 puffs bid.' What is the days' supply?
- 25 days
- 200 days
- 100 days
- 50 days
Correct answer: 50 days
The correct answer is 50 days. Two puffs twice daily equals 4 puffs per day; 200÷4=50 days.
- A prescription for insulin reads 'inject 20 units SC qAM.' A U-100 vial contains 10 mL. What days' supply should be entered?
- 25 days
- 100 days
- 50 days
- 20 days
Correct answer: 50 days
The correct answer is 50 days. A 10 mL U-100 vial contains 1,000 units (100 units/mL×10 mL); 1,000÷20=50 days.
- When entering patient information for a new profile, which identifier is most important to confirm to ensure age-appropriate dosing and avoid duplicate records?
- The patient's email address
- The patient's date of birth
- The patient's preferred pharmacy hours
- The patient's marital status
Correct answer: The patient's date of birth
The correct answer is the patient's date of birth. Date of birth confirms identity, prevents duplicate or mismatched profiles, and supports age-appropriate dose checking.
- A technician processes a sig 'gtt ii AU bid.' What does 'AU' indicate?
- Both eyes
- Right eye
- Both ears
- Left ear
Correct answer: Both ears
The correct answer is both ears. 'AU' (auris uterque) means both ears, so two drops are instilled in each ear twice daily.
- A prescriber's sig states 'SL prn chest pain.' What route is 'SL'?
- Sublingual
- Subcutaneous
- Subdermal
- Sublabial irrigation
Correct answer: Sublingual
The correct answer is sublingual. 'SL' means the dose is placed under the tongue, a route commonly used for fast-acting nitroglycerin for chest pain.
- When processing a prescription that calls for a 90-day supply, what is the primary benefit recognized by many insurance plans?
- It eliminates the need for a prescriber signature
- It exempts the drug from DUR checks
- It removes all copays
- It can lower the per-day cost and improve adherence with fewer refills
Correct answer: It can lower the per-day cost and improve adherence with fewer refills
The correct answer is that it can lower the per-day cost and improve adherence with fewer refills. Many plans incentivize 90-day fills for maintenance medications to support adherence.
- During order entry the system flags a 'drug-drug interaction' alert between warfarin and a new antibiotic. What is the appropriate technician action?
- Override the alert silently and dispense
- Forward the alert to the pharmacist for clinical review
- Delete the warfarin from the profile
- Reduce the antibiotic dose automatically
Correct answer: Forward the alert to the pharmacist for clinical review
The correct answer is to forward the alert to the pharmacist for clinical review. Interaction alerts require professional judgment; the pharmacist resolves clinical DUR flags before dispensing.
- A prescription reads 'one tablespoonful PO daily.' How many milliliters equal one tablespoonful for label conversion?
Correct answer: 15 mL
The correct answer is 15 mL. One tablespoonful equals 15 mL, whereas one teaspoonful equals 5 mL.
- A liquid prescription is written for 240 mL with the sig '15 mL PO bid.' What is the days' supply?
- 4 days
- 16 days
- 12 days
- 8 days
Correct answer: 8 days
The correct answer is 8 days. Fifteen mL twice daily is 30 mL/day; 240÷30=8 days.
- When verifying an electronic prescription (e-prescription) during entry, what is a key advantage over a handwritten order?
- It eliminates handwriting misinterpretation and reduces transcription errors
- It removes the need for any DUR check
- It allows refills on Schedule II drugs
- It does not require patient information
Correct answer: It eliminates handwriting misinterpretation and reduces transcription errors
The correct answer is that it eliminates handwriting misinterpretation and reduces transcription errors. E-prescriptions transmit legible, structured data directly into the pharmacy system.
- A prescription is received as a fax. Which type of medication generally CANNOT be dispensed from a faxed prescription alone (with limited exceptions)?
- Oral antihistamines
- Over-the-counter antacids
- Topical antibiotic creams
- Most Schedule II controlled substances
Correct answer: Most Schedule II controlled substances
The correct answer is most Schedule II controlled substances. Faxed C-II prescriptions generally require the original signed prescription before dispensing, aside from specific federal exceptions.
- A sig reads '1 patch transdermally q72h.' How many patches are needed for a 30-day supply?
- 30 patches
- 10 patches
- 15 patches
- 20 patches
Correct answer: 10 patches
The correct answer is 10 patches. One patch every 72 hours equals one patch every 3 days; 30÷3=10 patches.
- During processing, a technician sees the sig 'i cap PO q AM and ii caps PO q PM.' How many capsules are used per day?
- 2 capsules
- 4 capsules
- 3 capsules
- 1 capsule
Correct answer: 3 capsules
The correct answer is 3 capsules. One capsule in the morning plus two capsules in the evening equals 3 capsules per day.
- A claim rejects with 'invalid prescriber ID.' Which prescriber identifier most commonly needs verification to resolve this?
- The prescriber's NPI or DEA number
- The patient's group number
- The pharmacy's BIN
- The drug's NDC
Correct answer: The prescriber's NPI or DEA number
The correct answer is the prescriber's NPI or DEA number. An invalid prescriber ID rejection usually means the NPI (or DEA for controlled substances) on file must be corrected.
- Which combination of fields on an insurance card is used to route a claim to the correct processor during adjudication?
- NDC and lot number
- Allergy list and diagnosis
- BIN and PCN
- Sig and quantity
Correct answer: BIN and PCN
The correct answer is BIN and PCN. The Bank Identification Number and Processor Control Number route the electronic claim to the proper third-party payer.
- A prescription sig reads 'ii gtt OS q4h.' Into which site and how often is the medication instilled?
- Two drops in the left ear at bedtime
- Two drops in the right eye every 4 days
- Two drops in both eyes once daily
- Two drops in the left eye every 4 hours
Correct answer: Two drops in the left eye every 4 hours
The correct answer is two drops in the left eye every 4 hours. 'OS' (oculus sinister) is the left eye and 'q4h' means every 4 hours.
- When entering a compounded prescription order, why must each ingredient's quantity and the final total quantity be recorded in the system?
- To set the retail markup only
- To ensure accurate beyond-use dating, pricing, and dispensing records
- Because compounds never require labels
- To avoid needing a prescriber signature
Correct answer: To ensure accurate beyond-use dating, pricing, and dispensing records
The correct answer is to ensure accurate beyond-use dating, pricing, and dispensing records. Documenting each ingredient and the total quantity supports correct labeling, billing, and traceability of the compound.
- A prescription reads 'prednisone taper: 4 tabs day 1-3, 3 tabs day 4-6, 2 tabs day 7-9, 1 tab day 10-12.' How many total tablets should be dispensed?
- 20 tablets
- 40 tablets
- 30 tablets
- 24 tablets
Correct answer: 30 tablets
The correct answer is 30 tablets. The taper is (4×3)+(3×3)+(2×3)+(1×3)=12+9+6+3=30 tablets.
- During order entry, the system performs a 'duplicate therapy' check. What does this DUR check identify?
- Two drugs from the same therapeutic class on the profile
- Whether the patient has insurance
- The drug's expiration date
- The pharmacy's inventory level
Correct answer: Two drugs from the same therapeutic class on the profile
The correct answer is two drugs from the same therapeutic class on the profile. A duplicate therapy alert flags overlapping medications to prevent additive effects or unnecessary duplication.
- A sig reads '1 tab PO qod.' How is this frequency translated for the patient label?
- Take 1 tablet by mouth daily
- Take 1 tablet by mouth four times a day
- Take 1 tablet by mouth every other day
- Take 1 tablet by mouth as needed
Correct answer: Take 1 tablet by mouth every other day
The correct answer is take 1 tablet by mouth every other day. 'Qod' means every other day, though ISMP recommends spelling it out because it is error-prone.
- When the technician selects 'workflow status: ready for verification' after entry, what is the next step in standard prescription processing?
- The patient picks up immediately without review
- The pharmacist performs the final clinical and product verification
- The drug is returned to stock
- The claim is reversed
Correct answer: The pharmacist performs the final clinical and product verification
The correct answer is that the pharmacist performs the final clinical and product verification. After data entry and filling, the pharmacist must verify the prescription before it is dispensed to the patient.
- A prescription quantity field reads 'dispense QS for 30 days.' What does 'QS' direct the technician to do?
- Dispense quickly within seconds
- Dispense a quantity sufficient to last 30 days
- Dispense the quarterly stock
- Dispense a quality-sample only
Correct answer: Dispense a quantity sufficient to last 30 days
The correct answer is dispense a quantity sufficient to last 30 days. 'QS' (quantum sufficit) means provide the amount needed to cover the stated supply duration.
- A prescription reads 'cefdinir 250 mg/5 mL, 7 mL PO bid x 10 days.' What total volume should be dispensed?
Correct answer: 140 mL
The correct answer is 140 mL. Seven mL twice daily equals 14 mL/day; over 10 days that is 14×10=140 mL.
- A prescription is written for 'amoxicillin 250 mg/5 mL, 1 tsp PO TID x 10 days.' How many milliliters should be dispensed to complete the full course?
Correct answer: 150 mL
The correct quantity is 150 mL. One teaspoon equals 5 mL, so each dose is 5 mL. Taken three times daily (TID) gives 15 mL per day, and over 10 days that totals 150 mL (15 mL x 10 days). Converting the household teaspoon measure to metric before multiplying by frequency and duration is the key order-entry step.
- When a new prescription is entered, the pharmacy system flags that the patient's third-party insurance has returned a 'refill too soon' rejection. What does this rejection most directly indicate?
- The medication's NDC has been discontinued by the manufacturer
- The remaining days' supply from the previous fill has not yet elapsed enough to allow a new claim
- The prescriber's DEA number is invalid for this drug
- The patient has exceeded the plan's annual deductible
Correct answer: The remaining days' supply from the previous fill has not yet elapsed enough to allow a new claim
The correct interpretation is that not enough days have passed since the prior fill. A 'refill too soon' rejection means the patient is requesting the medication before the insurer's percentage of the previous days' supply has been used, so the claim is denied until the allowable refill date. It is not related to a discontinued NDC, an invalid DEA number, or the deductible.
- A prescription directs 'apply topically to affected area BID' for a 30 g tube of cream that lasts the patient exactly 15 days. What is the calculated days' supply the technician should enter if a 60 g tube is dispensed instead?
- 15 days
- 45 days
- 30 days
- 60 days
Correct answer: 30 days
The correct days' supply is 30 days. If a 30 g tube lasts 15 days at the same BID usage rate, then doubling the quantity to 60 g doubles the duration to 30 days. Days' supply for topical products scales proportionally with the amount dispensed when the application rate is unchanged.
- During order entry, a technician notices the prescriber wrote the drug name using a sound-alike abbreviation on the ISMP error-prone abbreviation list. What is the most appropriate action before processing?
- Select whichever drug appears first alphabetically in the system
- Dispense the lower-cost option of the two possible drugs
- Enter both medications and let the pharmacist choose at verification
- Contact the prescriber to clarify the intended medication rather than assuming
Correct answer: Contact the prescriber to clarify the intended medication rather than assuming
The correct action is to contact the prescriber for clarification. Error-prone and sound-alike abbreviations create ambiguity that can cause the wrong drug to be dispensed, so the order should never be processed on assumption, cost, alphabetical order, or by entering duplicate entries. Clarifying the prescriber's intent during order entry prevents a medication error downstream.
- A sig reads 'ii gtt AU q8h.' How should this be translated for the patient-facing label?
- Instill 2 drops in both eyes every 8 hours
- Instill 2 drops in both ears every 8 hours
- Instill 2 drops in the right ear every 8 hours
- Take 2 tablets by mouth every 8 hours
Correct answer: Instill 2 drops in both ears every 8 hours
The correct translation is 2 drops in both ears every 8 hours. 'Gtt' means drops, 'AU' is the abbreviation for both (each) ears, and 'q8h' means every 8 hours. 'AU' refers to ears, not eyes (which would use 'OU'), and the route is otic, not oral.
- A claim is submitted and the insurer returns a paid response showing a copay of $35 but the usual cash price is $22. What should the technician do during processing?
- Automatically charge the insurance copay because a claim was submitted
- Reverse the claim and refuse to fill the prescription
- Inform the patient that the cash price is lower so they can choose the less expensive option
- Split the difference and charge the patient $28.50
Correct answer: Inform the patient that the cash price is lower so they can choose the less expensive option
The correct action is to inform the patient that the cash price is lower so they can choose. When the adjudicated copay exceeds the cash price, the patient benefits from paying cash, and clawback gag clauses that previously prevented disclosure are no longer permitted. The technician should not default to the higher copay, refuse the fill, or invent an averaged price.
- An order requires preparing 250 mL of a 1/2-strength solution from a stock 10% solution. How many milliliters of the 10% stock are needed (the final solution should be 5%)?
- 250 mL
- 62.5 mL
- 100 mL
- 125 mL
Correct answer: 125 mL
The correct volume is 125 mL of the 10% stock. Using C1V1=C2V2: (10%)(V1)=(5%)(250 mL), so V1=105×250=125 mL. The remaining 125 mL of diluent is added to reach the final 250 mL volume of 5% solution.
- While entering a controlled substance prescription, the technician sees the prescriber's DEA number listed as 'BW1234563.' Using the DEA checksum, is the number valid?
- Valid - the sum (1+3+5)+2×(2+4+6)=9+24=33 ends in 3, matching the last digit
- Invalid - the first letter must always be 'A'
- Invalid - DEA numbers cannot contain a checksum digit
- Valid - because it contains exactly nine characters
Correct answer: Valid - the sum (1+3+5)+2×(2+4+6)=9+24=33 ends in 3, matching the last digit
The correct answer is that the number is valid by the checksum. Adding the 1st, 3rd, and 5th digits (1+3+5=9), then twice the sum of the 2nd, 4th, and 6th digits (2×[2+4+6]=24), gives 33, whose last digit (3) matches the seventh digit of the number. Mere character count or a required leading 'A' does not establish validity.
- A prescription for warfarin is entered and the system generates a drug-drug interaction alert with a concurrent NSAID. What is the correct order-processing response for the technician?
- Override the alert because warfarin is a commonly filled medication
- Delete the warfarin order to remove the interaction
- Forward the alert to the pharmacist for clinical review rather than overriding it independently
- Reduce the warfarin dose entered to half the prescribed amount
Correct answer: Forward the alert to the pharmacist for clinical review rather than overriding it independently
The correct response is to forward the alert to the pharmacist for clinical review. Interpreting and resolving drug-drug interaction alerts is a clinical judgment that falls within the pharmacist's scope, so the technician should not override, delete, or alter the dose. Routing the alert ensures the interaction is properly evaluated before dispensing.
- A prescription reads 'phenytoin 100 mg, take 1 capsule PO TID, dispense #90.' What days' supply should be entered for the third-party claim?
- 90 days
- 45 days
- 10 days
- 30 days
Correct answer: 30 days
The correct days' supply is 30 days. Taking 1 capsule three times daily (TID) means 3 capsules are used per day, so 90 capsules divided by 3 capsules per day equals 30 days. Dividing the total quantity dispensed by the number of units consumed daily yields the days' supply.
- During order entry the technician must select the correct product, and the system lists two entries with NDCs differing only in the middle segment. What does the middle segment of an NDC identify?
- The specific drug, strength, and dosage form (product code)
- The manufacturer or labeler
- The package size and type
- The therapeutic equivalence rating
Correct answer: The specific drug, strength, and dosage form (product code)
The correct answer is the product code, which identifies the specific drug, strength, and dosage form. In a National Drug Code, the first segment is the labeler/manufacturer, the second (middle) segment is the product code, and the third segment is the package code. A difference in the middle segment therefore signals a different strength or dosage form.
- A prescriber transmits an e-prescription for a Schedule II medication. Before processing, what is a required feature of a valid electronic prescription for controlled substances (EPCS)?
- The prescription was faxed as a backup to the electronic copy
- The prescriber used two-factor authentication to sign the prescription through a DEA-certified system
- The patient verbally confirmed the order over the phone
- The prescription omits the prescriber's DEA number to protect privacy
Correct answer: The prescriber used two-factor authentication to sign the prescription through a DEA-certified system
The correct requirement is that the prescriber signed via two-factor authentication through a DEA-certified EPCS system. Federal rules require identity proofing and two-factor authentication for electronically prescribing controlled substances. A fax backup, a verbal patient confirmation, or omitting the DEA number does not satisfy EPCS validity requirements.
- A patient taking lisinopril for hypertension is also prescribed spironolactone for heart failure. Why should the technician flag this combination for the pharmacist?
- Both drugs can raise serum potassium, so combining an ACE inhibitor with a potassium-sparing diuretic increases the risk of hyperkalemia.
- Both drugs lower potassium, increasing the risk of dangerous hypokalemia.
- Spironolactone deactivates lisinopril, making the blood pressure medication ineffective.
- The combination causes the two tablets to bind together in the stomach and block absorption.
Correct answer: Both drugs can raise serum potassium, so combining an ACE inhibitor with a potassium-sparing diuretic increases the risk of hyperkalemia.
The combination should be flagged because both drugs raise serum potassium: ACE inhibitors such as lisinopril reduce aldosterone-driven potassium excretion, and spironolactone is a potassium-sparing diuretic, so together they increase the risk of hyperkalemia and may warrant potassium monitoring.
- Generic drug names often share a stem that signals the drug class. Antibiotics whose generic names end in the suffix '-floxacin', such as ciprofloxacin and levofloxacin, belong to which class?
- Fluoroquinolones
- Macrolides
- Aminoglycosides
- Sulfonamides
Correct answer: Fluoroquinolones
Drugs ending in '-floxacin' are fluoroquinolones; ciprofloxacin and levofloxacin are broad-spectrum fluoroquinolone antibiotics, a class distinct from macrolides, aminoglycosides, and sulfonamides.
- A patient picks up a prescription for the brand drug Zithromax, an antibiotic, and asks the technician for its generic name. What is the correct generic name?
- Azithromycin
- Amoxicillin
- Cephalexin
- Ciprofloxacin
Correct answer: Azithromycin
The generic name of Zithromax is azithromycin, a macrolide antibiotic; amoxicillin, cephalexin, and ciprofloxacin are different antibiotics from other classes.
- A patient is dispensed ferrous sulfate for iron-deficiency anemia and asks how to take it for best absorption. Which counseling point is most appropriate?
- Take it on an empty stomach when tolerated, and taking it with vitamin C (or orange juice) can enhance iron absorption.
- Always take it together with an antacid or a calcium supplement to improve absorption.
- Take it with a large glass of milk to maximize how much iron is absorbed.
- Crush it and mix it into a high-fiber bran cereal to speed up absorption.
Correct answer: Take it on an empty stomach when tolerated, and taking it with vitamin C (or orange juice) can enhance iron absorption.
Ferrous sulfate is best absorbed on an empty stomach, and vitamin C (such as orange juice) enhances iron absorption; antacids, calcium, milk (calcium), and high-fiber foods all reduce iron absorption and should be separated from the dose.
- Metoclopramide is dispensed to a patient for nausea and to improve gastric emptying. To which drug class and use category does metoclopramide primarily belong?
- It is a prokinetic agent and antiemetic that increases gastrointestinal motility.
- It is a proton pump inhibitor that blocks acid secretion in the stomach.
- It is a bulk-forming laxative used to relieve constipation.
- It is an H2-receptor antagonist used to heal ulcers.
Correct answer: It is a prokinetic agent and antiemetic that increases gastrointestinal motility.
Metoclopramide is a prokinetic agent and antiemetic that increases gastrointestinal motility and accelerates gastric emptying; it is not a proton pump inhibitor, a laxative, or an H2-receptor antagonist.
- A technician is preparing to fill an order for an extended-release (ER) tablet for a patient who has difficulty swallowing. Why is it a patient-safety concern to crush an extended-release tablet?
- Crushing an extended-release tablet can destroy the controlled-release mechanism and cause the entire dose to be released at once, risking toxicity.
- Crushing an extended-release tablet has no clinical effect and is always acceptable for any patient.
- Crushing the tablet causes it to lose all of its active ingredient before it reaches the patient.
- Crushing the tablet converts the medication into a controlled substance requiring a new prescription.
Correct answer: Crushing an extended-release tablet can destroy the controlled-release mechanism and cause the entire dose to be released at once, risking toxicity.
Crushing an extended-release tablet is a safety concern because it can destroy the controlled-release design and dump the full dose immediately (dose dumping), risking toxicity; the technician should alert the pharmacist rather than assume an ER product can be crushed.
- Before handing a completed prescription to a patient at the point of sale, using two patient identifiers (such as full name and date of birth) is recommended primarily because it:
- Confirms the medication is going to the correct patient and helps prevent wrong-patient dispensing errors.
- Is required only to comply with insurance billing rules and has no safety purpose.
- Speeds up the transaction by skipping the need to verify the prescription label.
- Eliminates the need for the pharmacist to perform a final verification of the prescription.
Correct answer: Confirms the medication is going to the correct patient and helps prevent wrong-patient dispensing errors.
Verifying two patient identifiers such as name and date of birth confirms the prescription is being given to the correct patient and helps prevent wrong-patient errors; it does not replace pharmacist verification or exist solely for billing.
