NCLEX PN Questions on Pharmacology Questions
Question 1 of 9
A prescription needs to be written for:
Correct Answer: D
Rationale: Choice D is correct because prescriptions are required for legend drugs (FDA-approved prescription drugs), most controlled drugs (DEA-regulated), and certain medical devices, covering all categories listed. Choice A is incorrect alone as it excludes controlled drugs and devices. Choice B is wrong by itself because it misses legend drugs and devices. Choice C is incorrect solo since it omits drugs entirely.
Question 2 of 9
The primary care NP sees a 12-month-old infant who needs the MMR, Varivax, influenza, and hepatitis A vaccines. The child's mother tells the NP that she is pregnant. The NP should:
Correct Answer: A
Rationale: The correct answer is A because live vaccines (MMR, Varivax) are safe for children despite maternal pregnancy. Choice B is incorrect (excludes MMR, Varivax). Choice C is wrong (excludes MMR). Choice D is inaccurate (withholding unnecessary).
Question 3 of 9
Resources that provide information about drugs in breast milk include:
Correct Answer: D
Rationale: Choice D is correct because LactMed specializes in breastfeeding drug data, Medline offers research, and PDR includes manufacturer info—all provide relevant details. Choice A is incorrect alone as it's one source. Choice B is wrong by itself because it's research-focused, not comprehensive. Choice C is incorrect solo since PDR is limited to labels.
Question 4 of 9
The disadvantage of e-prescribing includes:
Correct Answer: A
Rationale: Choice A is correct because computer downtime or outages disrupt e-prescribing, delaying care, a known limitation. Choice B is incorrect as improved legibility is an advantage, not a disadvantage. Choice C is wrong because reduced errors are a benefit. Choice D is incorrect since confidentiality is enhanced, not a drawback.
Question 5 of 9
The primary care NP sees a 12-month-old infant who needs the MMR, Varivax, influenza, and hepatitis A vaccines. The child's mother tells the NP that she is pregnant. The NP should:
Correct Answer: A
Rationale: The correct answer is A because live vaccines (MMR, Varivax) are safe for children despite maternal pregnancy. Choice B is incorrect (excludes MMR, Varivax). Choice C is wrong (excludes MMR). Choice D is inaccurate (withholding unnecessary).
Question 6 of 9
Drugs that may increase the risk of falls in the elderly include:
Correct Answer: B
Rationale: Choice B is correct because benzodiazepines increase fall risk in the elderly by causing sedation and impaired coordination, per Beers Criteria. Choice A is incorrect as acetaminophen doesn't affect balance. Choice C is wrong because amoxicillin lacks fall-related ADRs. Choice D is incorrect since only benzodiazepines apply.
Question 7 of 9
CRNAs in most states:
Correct Answer: C
Rationale: The correct answer is C because CRNAs in most states can order and administer controlled substances without full prescriptive authority, as they dispense directly. Choice A is incorrect since a DEA number isn’t required without prescriptive authority. Choice B is wrong as only five states grant full authority. Choice D is inaccurate as supervision isn’t always required.
Question 8 of 9
James has hypothalamic-pituitary-adrenal axis suppression from chronic prednisone (a corticosteroid) use. He is at risk for what type of adverse drug reaction?
Correct Answer: B
Rationale: Choice B is correct because hypothalamic-pituitary-adrenal suppression from chronic prednisone is a type C ADR, linked to long-term use causing cumulative effects on endocrine function. Choice A is incorrect as type B is idiosyncratic, not chronic. Choice C (type E) is wrong because type E involves withdrawal effects, not ongoing suppression. Choice D (type F) is incorrect as type F is dose reduction failure, not applicable here.
Question 9 of 9
Drugs that should be avoided in transgender women receiving estrogen therapy include:
Correct Answer: A
Rationale: Choice A is correct because testosterone opposes estrogen's feminizing effects in transgender women, undermining therapy goals, so it's avoided. Choice B is incorrect as progestins may complement estrogen, not always avoided. Choice C is wrong because anticholinergics aren't contraindicated with estrogen. Choice D is incorrect since only testosterone fits.
