An example of a first-dose reaction that may occur includes:
- A. Orthostatic hypotension that does not occur with repeated doses
- B. Purple glove syndrome with phenytoin use
- C. Hemolytic anemia from ceftriaxone use
- D. Contact dermatitis from neomycin use
Correct Answer: A
Rationale: Choice A is correct because orthostatic hypotension can occur with a first dose of drugs like antihypertensives, subsiding as the body adjusts, a classic first-dose reaction. Choice B is incorrect as purple glove syndrome is a rare phenytoin effect, not first-dose specific. Choice C is wrong because hemolytic anemia is a type II reaction, not first-dose. Choice D is incorrect since contact dermatitis is a delayed, not first-dose, reaction.

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.
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.
Signs of controlled substance misuse include:
- A. Requesting early refills
- B. Reporting lost prescriptions
- C. Using multiple prescribers
- D. All of the above
Correct Answer: D
Rationale: Choice D is correct because early refills, lost prescription claims, and multiple prescribers are classic misuse signs, per DEA and clinical red flags. Choice A is incorrect alone as it's one sign. Choice B is wrong by itself because lost reports are just part. Choice C is incorrect solo since multiple prescribers is only one indicator.
Herbal products that may increase INR include:
- A. Ginkgo biloba
- B. St John's wort
- C. Valerian root
- D. All of the above
Correct Answer: A
Rationale: Choice A is correct because ginkgo biloba can increase INR by enhancing warfarin's effect through antiplatelet activity, risking bleeding. Choice B is incorrect as St John's wort induces CYP2C9, decreasing INR and warfarin efficacy. Choice C is wrong because valerian root doesn't significantly alter INR. Choice D is incorrect since only ginkgo biloba increases INR.
Risks associated with polypharmacy include:
- A. Increased adverse drug reactions
- B. Drug-drug interactions
- C. Nonadherence
- D. All of the above
Correct Answer: D
Rationale: Choice D is correct because polypharmacy raises ADR risk (more drugs, more side effects), interactions (competing metabolism), and nonadherence (complex regimens), per geriatric studies. Choice A is incorrect alone as it's one risk. Choice B is wrong by itself because interactions are just part. Choice C is incorrect solo since nonadherence is only one issue.
