Drugs that may cause increased adverse effects in women include:
- A. Lipid-soluble drugs
- B. Water-soluble drugs
- C. Drugs that are highly protein bound
- D. All of the above
Correct Answer: B
Rationale: Choice B is correct because women's lower lean mass reduces the volume of distribution for water-soluble drugs, increasing concentrations and ADR risk. Choice A is incorrect as lipid-soluble drugs distribute more in fat, not necessarily causing more ADRs. Choice C is wrong because protein binding isn't sex-specific enough here. Choice D is incorrect since only water-soluble drugs align.

The primary care NP sees a 4-year-old child who has received four doses of PCV 7 in the first 15 months of life. The NP should administer:
- A. PCV 7.
- B. PCV 13.
- C. PPV 23.
- D. no PCV.
Correct Answer: B
Rationale: The correct answer is B because children under 5 with PCV 7 series should get one PCV 13 dose. Choice A is incorrect (PCV 7 outdated). Choice C is wrong (PPV 23 not for this age). Choice D is inaccurate (vaccine needed).
Drugs that are Pregnancy Category C:
- A. Have known fetal risks that outweigh the benefits
- B. Have no adequate studies in pregnant women
- C. Are proven safe in pregnancy
- D. All of the above
Correct Answer: B
Rationale: Choice B is correct because Category C drugs lack sufficient human studies, with animal studies showing risk or no data, used only if benefits justify, per FDA. Choice A is incorrect as that defines Category X, not C. Choice C is wrong because Category B, not C, indicates safety. Choice D is incorrect since only B fits Category C.
Pharmacokinetic changes in the elderly that affect drug dosing include:
- A. Decreased renal function
- B. Increased liver metabolism
- C. Decreased body fat
- D. All of the above
Correct Answer: A
Rationale: Choice A is correct because decreased renal function in the elderly slows drug excretion, requiring dose adjustments to prevent accumulation, per geriatric pharmacology. Choice B is incorrect as liver metabolism decreases, not increases. Choice C is wrong because body fat increases, not decreases. Choice D is incorrect since only A is accurate.
Strategies to improve adherence to medication regimes include:
- A. Assuming that the patient understands the directions on the prescription bottle
- B. Using pictograms or illustrations to explain how to take the medication
- C. Assuming that the patient's health literacy level is the same as their general literacy
- D. Using the patient's preferred language when there is a language barrier
Correct Answer: B
Rationale: Choice B is correct because pictograms clarify instructions visually, aiding comprehension and adherence, especially for low-literacy patients. Choice A is incorrect as assuming understanding can lead to errors. Choice C is wrong because health literacy varies from general literacy, needing specific attention. Choice D is incorrect here as it's a good strategy but not listed in this question's options correctly—B fits best.
Upregulation or hypersensitization may lead to:
- A. Increased response to a drug
- B. Decreased response to a drug
- C. An exaggerated response if the drug is withdrawn
- D. Refractoriness or complete lack of response
Correct Answer: C
Rationale: Choice C is correct because upregulation (more receptors) or hypersensitization from chronic antagonist use can cause an exaggerated rebound response if withdrawn, as seen with beta blockers. Choice A is incorrect as increased response occurs during use, not withdrawal. Choice B is wrong because decreased response isn't typical of upregulation. Choice D is incorrect since refractoriness relates to agonists, not this scenario.
