LPN Pharmacology Multiple Choice Questions Questions
Question 1 of 9
Drugs that may increase bleeding risk in the elderly include:
Correct Answer: D
Rationale: Choice D is correct because aspirin (antiplatelet), warfarin (anticoagulant), and ibuprofen (NSAID) all increase bleeding risk, especially in the elderly with fragile vessels, per studies. Choice A is incorrect alone as it's one drug. Choice B is wrong by itself because warfarin is just part. Choice C is incorrect solo since ibuprofen is only one agent.
Question 2 of 9
Requirements for generic drugs include:
Correct Answer: A
Rationale: Choice A is correct because the FDA mandates generics have the same active ingredient, dosage, and route as brand-name drugs for bioequivalence. Choice B is incorrect as cost isn't a requirement—it varies. Choice C is wrong because color isn't regulated. Choice D is incorrect since only A is required.
Question 3 of 9
Drug antagonism is best defined as an effect of a drug that:
Correct Answer: B
Rationale: Choice B is correct because drug antagonism occurs when one drug's effect is altered (usually reduced) by another, a classic interaction like beta blockers countering adrenaline. Choice A is incorrect as dependence isn't antagonism. Choice C is wrong because metabolism timing isn't the definition. Choice D is incorrect since it's a consequence, not the defining feature.
Question 4 of 9
Strategies to reduce polypharmacy include:
Correct Answer: D
Rationale: Choice D is correct because reconciliation (reviewing meds), deprescribing (stopping unneeded drugs), and education (improving adherence) all reduce polypharmacy risks, per clinical guidelines. Choice A is incorrect alone as it's one strategy. Choice B is wrong by itself because deprescribing is just part. Choice C is incorrect solo since education is only one approach.
Question 5 of 9
A primary care NP provides primary care for a woman who has HIV. The woman asks the NP if she will ever be able to have children. The NP should tell her:
Correct Answer: D
Rationale: The correct answer is D because therapy reduces, but doesn’t eliminate, fetal transmission risk. Choice A is incorrect (some are safe). Choice B is wrong (lactation not recommended). Choice C is inaccurate (risk remains).
Question 6 of 9
Drugs that may increase bleeding risk in the elderly include:
Correct Answer: D
Rationale: Choice D is correct because aspirin (antiplatelet), warfarin (anticoagulant), and ibuprofen (NSAID) all increase bleeding risk, especially in the elderly with fragile vessels, per studies. Choice A is incorrect alone as it's one drug. Choice B is wrong by itself because warfarin is just part. Choice C is incorrect solo since ibuprofen is only one agent.
Question 7 of 9
An NP orders an inhaled corticosteroid 2 puffs twice daily and an albuterol metered-dose inhaler 2 puffs every 4 hours as needed for cough or wheezing for a 65-year-old patient with recent onset of reactive airways disease who reports symptoms occurring every 1 or 2 weeks. At a follow-up appointment several months later, the patient reports no change in frequency of symptoms. The NP's initial action should be to:
Correct Answer: C
Rationale: The correct answer is C because assessing medication use ensures compliance and correct technique before further interventions. Choice A is incorrect as spirometry isn’t the first step. Choice B is wrong since systemic steroids aren’t initial. Choice D is inaccurate as education follows compliance check.
Question 8 of 9
An NP would prescribe the liquid form of ibuprofen for a 6-year-old child because:
Correct Answer: B
Rationale: Choice B is correct because a 6-year-old may struggle to swallow pills, making liquid ibuprofen easier to administer and ensuring compliance. Choice A is incorrect as liquid forms aren't inherently less irritating—irritation depends on the drug. Choice C is wrong because liquids still undergo first-pass metabolism when swallowed. Choice D is incorrect since dosing frequency depends on pharmacokinetics, not form.
Question 9 of 9
Drugs that are contraindicated in men with benign prostatic hyperplasia include:
Correct Answer: B
Rationale: Choice B is correct because anticholinergics worsen urinary retention in BPH by relaxing bladder muscles, contraindicated per urology guidelines. Choice A is incorrect as testosterone's role is debated, not absolute. Choice C is wrong because alpha blockers treat BPH. Choice D is incorrect since only anticholinergics apply.
