Food or drink that should be avoided when taking a prescription for simvastatin includes:
- A. Milk
- B. Orange juice
- C. Grapefruit juice
- D. Green leafy vegetables
Correct Answer: C
Rationale: Choice C is correct because grapefruit juice inhibits CYP3A4, which metabolizes simvastatin, increasing drug levels and rhabdomyolysis risk, so it's to be avoided. Choice A is incorrect as milk doesn't affect simvastatin significantly. Choice B is wrong because orange juice has no notable interaction. Choice D is incorrect since green leafy vegetables don't impact simvastatin metabolism.

Michael calls the clinic to ask about taking fish oil supplements with his simvastatin prescription. The NP's response is:
- A. Avoid fish oil as it will increase your risk of bleeding.
- B. There are no known interactions; it is safe to take fish oil with simvastatin.
- C. Avoid fish oil as it will decrease the effectiveness of the simvastatin.
- D. Fish oil should only be taken with simvastatin if prescribed by your cardiologist.
Correct Answer: B
Rationale: Choice B is correct because fish oil (omega-3s) and simvastatin both lower triglycerides with no significant interactions; studies show they're safe together, enhancing lipid benefits. Choice A is incorrect as fish oil's bleeding risk is minimal and not amplified by simvastatin. Choice C is wrong because fish oil doesn't reduce simvastatin's efficacy—they're complementary. Choice D is incorrect since no prescription is needed for this safe combination.
When determining drug treatment, the NP prescriber should:
- A. Always use evidence-based guidelines
- B. Individualize the drug choice for the specific patient
- C. Rely on his or her experience when prescribing for complex patients
- D. Use the newest drug on the market for the condition being treated
Correct Answer: B
Rationale: Choice B is correct because tailoring treatment to the patient's unique factors—age, comorbidities, preferences—optimizes efficacy and safety. Choice A is incorrect as guidelines inform but don't dictate every case. Choice C is wrong because experience alone may lack evidence support. Choice D is incorrect since newest drugs aren't always best—evidence and patient fit matter more.
Strategies to avoid counterfeit drugs include:
- A. Purchasing from licensed pharmacies
- B. Checking drug packaging
- C. Avoiding online purchases from unverified sources
- D. All of the above
Correct Answer: D
Rationale: Choice D is correct because using licensed pharmacies (regulated supply), checking packaging (authenticity cues), and avoiding unverified online sources (high-risk) all prevent counterfeit drug use, per FDA advice. Choice A is incorrect alone as it's one strategy. Choice B is wrong by itself because packaging is just part. Choice C is incorrect solo since online avoidance is only one method.
A patient develops hepatotoxicity from chronic acetaminophen use. The primary care NP may recommend:
- A. milk thistle.
- B. chondroitin.
- C. coenzyme Q.
- D. glucosamine.
Correct Answer: A
Rationale: The correct answer is A because milk thistle protects the liver from hepatotoxins like acetaminophen. Choices B, C, and D are incorrect as they lack this hepatoprotective effect.
The healthcare provider assesses a client who has been prescribed furosemide (Lasix) for cardiac disease. Which electrocardiographic change would be a concern for a client taking a diuretic?
- A. Tall, spiked T waves
- B. A prolonged QT interval
- C. A widening QRS complex
- D. Presence of a U wave
Correct Answer: D
Rationale: The presence of a U wave is often associated with hypokalemia, a possible side effect of diuretic therapy like furosemide. Hypokalemia can lead to U wave formation on an electrocardiogram, making the presence of U waves a concerning finding in clients taking diuretics. Tall, spiked T waves are typically seen in hyperkalemia, not hypokalemia. A prolonged QT interval is more commonly associated with conditions like Long QT syndrome or certain medications, not specifically with diuretics. A widening QRS complex is usually seen in conditions affecting the conduction system of the heart, such as bundle branch blocks, rather than being directly related to diuretic use.
