NCLEX PN Pharmacology Practice Questions Questions
Question 1 of 9
Risks to the breastfeeding infant include:
Correct Answer: A
Rationale: Choice A is correct because sedating drugs (e.g., opioids) in breast milk can cause infant drowsiness or respiratory depression, a primary risk. Choice B is incorrect as no drugs typically ‘stimulate growth' in this context—growth is natural. Choice C is wrong because acetaminophen is safe, with minimal risk. Choice D is incorrect since only A is a significant concern.
Question 2 of 9
Sarah developed a rash after using a topical medication. This is a type __ allergic drug reaction.
Correct Answer: D
Rationale: Choice D is correct because a rash from topical medication is typically a type IV allergic reaction, a delayed hypersensitivity mediated by T-cells, common in skin responses. Choice A is incorrect as type I is immediate, like anaphylaxis, not a rash. Choice B is wrong because type II is cytotoxic, not skin-based. Choice C is incorrect since type III involves immune complexes, not topical rashes.
Question 3 of 9
The Vaccine Adverse Events Reporting System is:
Correct Answer: B
Rationale: Choice B is correct because VAERS is a voluntary system for providers and consumers to report vaccine ADRs, aiding safety monitoring without mandate. Choice A is incorrect as reporting isn't mandatory. Choice C is wrong because VAERS collects data, not sends alerts. Choice D is incorrect since it's not activated by proven effects—it's ongoing surveillance.
Question 4 of 9
Risks to the breastfeeding infant include:
Correct Answer: A
Rationale: Choice A is correct because sedating drugs (e.g., opioids) in breast milk can cause infant drowsiness or respiratory depression, a primary risk. Choice B is incorrect as no drugs typically ‘stimulate growth' in this context—growth is natural. Choice C is wrong because acetaminophen is safe, with minimal risk. Choice D is incorrect since only A is a significant concern.
Question 5 of 9
As patients age, it becomes particularly important to increase their intake of:
Correct Answer: D
Rationale: The correct answer is D because elderly are prone to B vitamin deficiencies due to poor intake. Choice A is incorrect (iron less critical). Choice B is wrong (omega-3 not primary). Choice C is inaccurate (vitamin C not highlighted).
Question 6 of 9
Drugs that should be avoided in patients who are CYP2D6 ultrarapid metabolizers include:
Correct Answer: B
Rationale: Choice B is correct because CYP2D6 ultrarapid metabolizers convert codeine to morphine too quickly, risking overdose and toxicity, so it should be avoided. Choice A is incorrect as acetaminophen's metabolism isn't significantly CYP2D6-dependent, posing less risk. Choice C is wrong because ibuprofen isn't metabolized by CYP2D6, so ultrarapid status is irrelevant. Choice D is incorrect since only codeine poses a specific danger here.
Question 7 of 9
The major reason for not crushing a sustained-release capsule is that, if crushed, the coated beads of the drugs could possibly result in:
Correct Answer: B
Rationale: Choice B is correct because crushing a sustained-release capsule releases all drug at once, bypassing controlled release, which can lead to toxic levels quickly. Choice A is incorrect as disintegration isn't harmful itself, just alters release. Choice C is wrong because malabsorption isn't the primary risk—overdose is. Choice D is incorrect since deterioration implies drug degradation, not the immediate danger of crushing.
Question 8 of 9
A patient has begun treatment for HIV. The primary care NP should monitor the patient's complete blood count (CBC) at least every __ months.
Correct Answer: B
Rationale: The correct answer is B because CBC monitoring every 3-6 months checks for toxicity, more if values are low. Choices A, C, and D are incorrect (outside standard range).
Question 9 of 9
Drugs that may cause increased adverse effects in children include:
Correct Answer: B
Rationale: Choice B is correct because tetracycline causes tooth discoloration and bone growth issues in children under 8, a significant ADR, unlike others. Choice A is incorrect as acetaminophen is safe at proper doses with minimal ADRs. Choice C is wrong because amoxicillin's ADRs (e.g., rash) are mild and manageable. Choice D is incorrect since only tetracycline poses a notable risk.
