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.

Drugs that may cause sedation in the elderly include:
- A. Benzodiazepines
- B. Antihistamines
- C. Opioids
- D. All of the above
Correct Answer: D
Rationale: Choice D is correct because benzodiazepines (e.g., lorazepam), antihistamines (e.g., diphenhydramine), and opioids (e.g., oxycodone) all cause sedation, increasing fall risk in the elderly, per Beers Criteria. Choice A is incorrect alone as it's one class. Choice B is wrong by itself because antihistamines are just part. Choice C is incorrect solo since opioids are only one group.
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.
Drugs that require refrigeration include:
- A. Insulin
- B. Amoxicillin suspension
- C. Vaccines
- D. All of the above
Correct Answer: D
Rationale: Choice D is correct because insulin (protein stability), amoxicillin suspension (post-reconstitution), and vaccines (biological potency) require refrigeration to maintain efficacy, per storage guidelines. Choice A is incorrect alone as it's one drug. Choice B is wrong by itself because amoxicillin is just part. Choice C is incorrect solo since vaccines are only one group.
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.
A 4-month-old infant has a viral illness with high fever and cough. The infant's parent asks the NP about what to give the infant to help with symptoms. The NP should prescribe which of the following?
- A. Aspirin to treat the fever
- B. Acetaminophen as needed
- C. Dextromethorphan for coughing
- D. An antibiotic to prevent increased infection
Correct Answer: B
Rationale: The correct answer is B because acetaminophen is safe for infants to reduce fever. Choice A is incorrect (aspirin risks Reye’s syndrome). Choice C is wrong (dextromethorphan risks respiratory depression). Choice D is inaccurate (antibiotics don’t treat viral illness).
