NCLEX PN Pharmacology Questions Questions
Question 1 of 9
The Beers Criteria are used to:
Correct Answer: B
Rationale: Choice B is correct because the Beers Criteria, by the American Geriatrics Society, identify drugs with high ADR risk in the elderly, guiding safer prescribing. Choice A is incorrect as it's not antibiotic-specific. Choice C is wrong because it doesn't set doses. Choice D is incorrect since only B applies.
Question 2 of 9
The U.S. Food and Drug Administration regulates:
Correct Answer: B
Rationale: Choice B is correct because the FDA regulates drug labeling, ensuring safety and efficacy information is accurate for all prescription and OTC drugs. Choice A is incorrect as prescribing is governed by state boards, not the FDA. Choice C is wrong because off-label use is allowed but not regulated by the FDA. Choice D is incorrect since educational offerings fall under other entities, not FDA control.
Question 3 of 9
Drugs that are receptor antagonists, such as beta blockers, demonstrate what property?
Correct Answer: C
Rationale: Choice C is correct because receptor antagonists, like beta blockers, block agonist effects, partially inhibiting their action without activating the receptor themselves. Choice A is incorrect as downregulation isn't typical; antagonists may cause upregulation. Choice B is wrong because abrupt discontinuation may cause rebound effects, but it's not their defining property. Choice D is incorrect since antagonists reduce, not exaggerate, responses to agonists.
Question 4 of 9
Drugs that may cause dependence include:
Correct Answer: D
Rationale: Choice D is correct because benzodiazepines (sedative dependence), opioids (physical addiction), and nicotine (psychological craving) all lead to dependence, per DSM-5 criteria. Choice A is incorrect alone as it's one class. Choice B is wrong by itself because opioids are just part. Choice C is incorrect solo since nicotine is only one substance.
Question 5 of 9
A patient who has HIV is being treated with Emtriva. The patient develops hepatitis B. The primary care NP should contact the patient's infectious disease specialist to discuss:
Correct Answer: B
Rationale: The correct answer is B because Truvada (Emtriva + tenofovir) treats both HIV and hepatitis B effectively. Choice A is incorrect (zidovudine not for hepatitis B). Choice C is wrong (tenofovir alone insufficient). Choice D is inaccurate (Combivir unnecessary).
Question 6 of 9
The Beers Criteria are used to:
Correct Answer: B
Rationale: Choice B is correct because the Beers Criteria, by the American Geriatrics Society, identify drugs with high ADR risk in the elderly, guiding safer prescribing. Choice A is incorrect as it's not antibiotic-specific. Choice C is wrong because it doesn't set doses. Choice D is incorrect since only B applies.
Question 7 of 9
Schedule IV drugs are characterized by:
Correct Answer: C
Rationale: Choice C is correct because Schedule IV drugs (e.g., diazepam) have low abuse potential compared to higher schedules, with accepted use, per DEA. Choice A is incorrect as high potential is Schedule II. Choice B is wrong because moderate is Schedule III. Choice D is incorrect since only C applies.
Question 8 of 9
A 40-year-old woman asks the primary care NP what she can do to minimize her risk of osteoporosis. She takes 800 mg of calcium and drinks 2 cups of skim milk each day. The NP should recommend that she:
Correct Answer: B
Rationale: The correct answer is B because high caffeine reduces calcium absorption, increasing osteoporosis risk. Choice A is incorrect (fat aids absorption). Choice C is wrong (high protein reduces absorption). Choice D is inaccurate (all sodas reduce calcium).
Question 9 of 9
A patient asks a primary care NP why herbal supplements are not regulated by the FDA. The nurse practitioner should tell the patient these products are not regulated by the FDA because they are:
Correct Answer: B
Rationale: The correct answer is B because herbal supplements avoid FDA regulation by not claiming to treat or cure diseases. Choice A is incorrect (natural status isn’t the reason). Choice C is wrong (DSHEA defines, doesn’t regulate directly). Choice D is inaccurate (Hatch-Richardson misstated).
