Quizlet Pharmacology Questions for LPN Questions
Question 1 of 9
A primary care nurse practitioner (NP) prescribes a drug to an 80-year-old African-American woman. When selecting a drug and determining the correct dose, the NP should understand that the knowledge of how age, race, and gender may affect drug excretion is based on an understanding of:
Correct Answer: B
Rationale: The correct answer is B because pharmacokinetics studies how the body processes drugs, including excretion affected by age, race, and gender. Choice A is incorrect as bioavailability focuses on drug availability, not excretion. Choice C is wrong since pharmacodynamics studies drug effects, not excretion. Choice D is inaccurate as it’s too broad and not specific to drug processing.
Question 2 of 9
A primary care nurse practitioner (NP) prescribes a drug to an 80-year-old African-American woman. When selecting a drug and determining the correct dose, the NP should understand that the knowledge of how age, race, and gender may affect drug excretion is based on an understanding of:
Correct Answer: B
Rationale: The correct answer is B because pharmacokinetics studies how the body processes drugs, including excretion affected by age, race, and gender. Choice A is incorrect as bioavailability focuses on drug availability, not excretion. Choice C is wrong since pharmacodynamics studies drug effects, not excretion. Choice D is inaccurate as it’s too broad and not specific to drug processing.
Question 3 of 9
A primary care NP is aware that many patients in the community use herbal remedies to treat various conditions. The NP understands the importance of:
Correct Answer: A
Rationale: The correct answer is A because NPs need knowledge of herbal remedies to guide patients safely. Choice B is incorrect (prescribing lacks evidence base). Choice C is wrong (stopping not practical). Choice D is inaccurate (unregulated but not inherently unsafe).
Question 4 of 9
In deciding which of multiple drugs used to use to treat a condition, the NP chooses Drug A because it:
Correct Answer: C
Rationale: Choice C is correct because choosing a drug covered by insurance ensures affordability and adherence, a practical consideration in rational drug selection. Choice A is incorrect as serious side effects typically deter use unless benefits outweigh risks, especially for non-life-threatening conditions. Choice B is wrong because dosing and location are secondary to efficacy and cost. Choice D is incorrect since insurance coverage is a valid factor.
Question 5 of 9
A patient who has HIV frequently expresses concerns about the costs of treatment. The primary care NP should:
Correct Answer: A
Rationale: The correct answer is A because underdosing risks resistance, worse than no treatment. Choice B is incorrect (half doses dangerous). Choice C is wrong (three agents needed). Choice D is inaccurate (holidays not recommended).
Question 6 of 9
A primary care NP is aware that many patients in the community use herbal remedies to treat various conditions. The NP understands the importance of:
Correct Answer: A
Rationale: The correct answer is A because NPs need knowledge of herbal remedies to guide patients safely. Choice B is incorrect (prescribing lacks evidence base). Choice C is wrong (stopping not practical). Choice D is inaccurate (unregulated but not inherently unsafe).
Question 7 of 9
Improper storage of drugs may lead to:
Correct Answer: D
Rationale: Choice D is correct because improper storage can reduce potency (degradation), increase toxicity (chemical changes), and alter appearance (e.g., discoloration), per pharmacology principles. Choice A is incorrect alone as it's one effect. Choice B is wrong by itself because toxicity is just part. Choice C is incorrect solo since appearance is only one outcome.
Question 8 of 9
A woman who is pregnant and is planning to breastfeed tells the primary care NP that she has never had chickenpox. The NP should:
Correct Answer: C
Rationale: The correct answer is C because live vaccines like Varivax are contraindicated in pregnancy but safe post-delivery during breastfeeding. Choice A is incorrect (pregnancy risk). Choice B is wrong (globulin not for prevention). Choice D is inaccurate (delaying unnecessary).
Question 9 of 9
Risks of off-label drug use include:
Correct Answer: D
Rationale: Choice D is correct because off-label use lacks FDA approval (unregulated indication), risks ADRs (untested context), and may have limited evidence, per pharmacology concerns. Choice A is incorrect alone as it's one risk. Choice B is wrong by itself because ADRs are just part. Choice C is incorrect solo since evidence is only one issue.
