Question 1 of 5
Which laboratory test is an indirect measure of atherosclerotic plaque?
Correct Answer: B
Rationale: The correct answer is B: C-reactive protein (CRP). CRP is an inflammatory marker that increases in response to inflammation associated with atherosclerosis. Elevated CRP levels indicate increased risk of atherosclerotic plaque formation. Homocysteine (A) is a marker for cardiovascular disease but not specific to atherosclerosis. LDL (C) is a direct measure of cholesterol levels, not plaque. ESR (D) is a non-specific marker for inflammation and does not directly indicate atherosclerotic plaque.
Question 2 of 5
Which hepatitis virus is most commonly known to be sexually transmitted?
Correct Answer: C
Rationale: The correct answer is C (Hepatitis B) because it is the most commonly known hepatitis virus to be sexually transmitted due to its presence in blood, semen, and other bodily fluids. Hepatitis A is primarily transmitted through contaminated food or water. Hepatitis C is mainly transmitted through blood contact, not commonly through sexual activity. Hepatitis D is only seen in individuals already infected with Hepatitis B. Therefore, Hepatitis B is the most likely to be transmitted sexually compared to the other options.
Question 3 of 5
Which of the following terms best describes the mechanism of action of metoprolol?
Correct Answer: B
Rationale: The correct answer is B: Beta one selective. Metoprolol is a beta-blocker that selectively targets beta-1 receptors in the heart, reducing heart rate and blood pressure. This specificity minimizes side effects compared to nonselective beta-blockers. Choice A is incorrect because metoprolol does not primarily act as an A1 antagonist. Choice C is incorrect as metoprolol is not nonselective and does not block alpha receptors. Choice D is incorrect because metoprolol does not block alpha receptors at all.
Question 4 of 5
Mild acne may be initially treated with:
Correct Answer: A
Rationale: The correct answer is A: OTC benzoyl peroxide. Initially treating mild acne with OTC benzoyl peroxide is effective as it helps to kill acne-causing bacteria, reduce inflammation, and unclog pores. It is a common first-line treatment for mild acne due to its efficacy and accessibility. Minocycline (B) is an oral antibiotic usually reserved for moderate to severe acne. Topical combined antibiotic (C) and topical retinoid (D) are also effective treatments, but typically prescribed for more moderate to severe cases of acne. Benzoyl peroxide is a safe and cost-effective option for mild acne, making it the best choice for initial treatment.
Question 5 of 5
VT has a history of subtherapeutic anticoagulation on warfarin (due to poor adherence) until the administration time was changed from evening to morning. The patient also frequently skips meals and takes antacids for reflux. The patient wants to take all medications at the same time of day. Select the statin that is optimal for this patient wanting to take medications in the morning.
Correct Answer: D
Rationale: The correct answer is D: Atorvastatin (Lipitor). Atorvastatin has a long half-life and can be taken at any time of day, making it suitable for this patient who wants to take all medications in the morning. Lovastatin, Fluvastatin, and Pravastatin have shorter half-lives and are typically recommended to be taken in the evening for optimal efficacy. Therefore, they are not ideal for this patient who wants to consolidate medication administration in the morning.
