Question 1 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 2 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 3 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.
Question 4 of 5
Which classification of oral hypoglycemic drugs decreases hepatic glucose production and increases insulin sensitivity and peripheral glucose uptake?
Correct Answer: C
Rationale: The correct answer is C: Biguanide (metformin). Metformin decreases hepatic glucose production by inhibiting gluconeogenesis and increases insulin sensitivity in peripheral tissues, which enhances glucose uptake. Sulfonylureas and meglitinides stimulate insulin secretion from the pancreas. Alpha-glycosidase inhibitors delay carbohydrate absorption in the gut. Metformin's dual mechanism of action makes it the correct choice for decreasing hepatic glucose production and increasing insulin sensitivity and peripheral glucose uptake.
Question 5 of 5
Metoclopramide (Reglan) carries a black box warning that it can cause tardive dyskinesia with long-term therapy.
Correct Answer: A
Rationale: The correct answer is A (TRUE). Metoclopramide (Reglan) does carry a black box warning due to the risk of tardive dyskinesia with long-term use. Tardive dyskinesia is characterized by involuntary movements of the face and body and can be irreversible. The warning emphasizes the importance of using metoclopramide for the shortest duration possible to minimize this risk. The other choices (B, C, D) are incorrect because the black box warning for tardive dyskinesia associated with metoclopramide is a well-documented fact supported by clinical evidence and regulatory agencies.
