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.

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.
Schedule II drugs are characterized by:
- A. High potential for abuse
- B. Low potential for abuse
- C. No accepted medical use
- D. All of the above
Correct Answer: A
Rationale: Choice A is correct because Schedule II drugs (e.g., oxycodone) have a high abuse potential with accepted medical use, per DEA rules. Choice B is incorrect as low potential is Schedule IV/V. Choice C is wrong because no medical use is Schedule I. Choice D is incorrect since only A applies.
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.

Clinical judgment in prescribing includes:
- A. Factoring in the cost to the patient of the medication prescribed
- B. Always prescribing the newest medication available for the disease process
- C. Handing out drug samples to poor patients
- D. Prescribing all generic medications to cut costs
Correct Answer: S
Rationale: Choice A is correct because clinical judgment involves balancing efficacy, safety, and cost to ensure patients can afford and adhere to treatment, which is critical for successful outcomes. Choice B is incorrect as always choosing the newest medication ignores evidence-based practice; newer drugs may lack long-term data or be unnecessarily expensive. Choice C is wrong because distributing samples isn't a sustainable prescribing strategy and may not meet ongoing needs. Choice D is also incorrect since mandating generics could compromise efficacy if a brand-name drug is clinically necessary.
