- A. Acetaminophen
- B. Pseudoephedrine
- C. Ibuprofen

Correct Answer: B
Rationale: Choice B is correct because pseudoephedrine, a decongestant, raises blood pressure via vasoconstriction, risky in hypertension, per guidelines. Choice A is incorrect as acetaminophen doesn't affect BP. Choice C is wrong because ibuprofen's BP effect is milder and not absolute avoidance. Choice D is incorrect since only pseudoephedrine is key.

Genetic testing prior to prescribing which drug could prevent serious adverse drug reactions?
- A. Acetaminophen
- B. Codeine
- C. Albuterol
- D. All of the above
Correct Answer: B
Rationale: Choice B is correct because genetic testing for CYP2D6 variants can prevent ADRs with codeine; poor metabolizers get no pain relief, while ultrarapid metabolizers risk morphine toxicity. Choice A is incorrect as acetaminophen metabolism isn't strongly tied to genetic variants causing serious ADRs. Choice C is wrong because albuterol's inhaled use has minimal genetic metabolism risks. Choice D is incorrect since only codeine benefits significantly from pre-prescribing genetic testing.
An NP is caring for a 70-year-old patient who reports having seasonal allergies with severe rhinorrhea. Using the Beers criteria, which of the following medications should the NP recommend for this patient?
- A. Loratadine (Claritin)
- B. Hydroxyzine (Vistaril)
- C. Diphenhydramine (Benadryl)
- D. Chlorpheniramine maleate (Chlorphen 12)

- A. Registers manufacturers and prescribers of controlled substances
- B. Regulates NP prescribing at the state level
- C. Sanctions providers who prescribe drugs off-label
- D. Provides prescribers with a number they can use for insurance billing
Correct Answer: A
Rationale: Choice A is correct because the DEA registers those handling controlled substances, issuing numbers for tracking and prescribing, its primary role. Choice B is incorrect as state boards, not the DEA, regulate NP prescribing. Choice C is wrong because off-label prescribing isn't DEA-regulated. Choice D is incorrect since the DEA number is for controlled substances, not insurance billing.
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.
Drugs that may interact with vaccines include:
- A. Immunosuppressants
- B. Antibiotics
- C. Antihistamines
- D. All of the above
Correct Answer: A
Rationale: Choice A is correct because immunosuppressants (e.g., prednisone) reduce vaccine efficacy by weakening immune response, per CDC guidelines. Choice B is incorrect as antibiotics don't typically affect vaccines. Choice C is wrong because antihistamines lack vaccine interactions. Choice D is incorrect since only immunosuppressants apply.
