Below question: don't know the correct combination. Below is what was picked but incorrect. When prescribing medication to infants, it is important for the provider to consider which fact? (Select all that apply)

Correct Answer: A

Rationale: The correct answer is A: Oral medications are contraindicated in infants. This is correct because infants have immature gastrointestinal systems, leading to reduced absorption and unpredictable drug levels when given orally. Choices B, C, and D are incorrect. B is incorrect as breastfeeding does not necessarily increase toxicity, it depends on the specific drug. C is incorrect because infants do have immature liver function but this affects drug metabolism, not contraindicating oral medications. D is incorrect as immature renal function does not mean excretion is less efficient, but rather can affect drug elimination speed.

Correct Answer: A

Rationale: The correct answer is A because CYP2D6 enzyme metabolizes tamoxifen into its active form, endoxifen. Poor metabolizers of tamoxifen may have reduced efficacy and increased risk of therapeutic failure. Testing for CYP2D6 variants can help identify these individuals. Choice B is incorrect because adverse drug reactions are not directly related to CYP2D6 metabolism. Choice C is incorrect as CYP2D6 testing does not assess for drug interactions. Choice D is incorrect as poor metabolizers may experience therapeutic failure due to reduced metabolism, not increased likelihood.

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.

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.

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.
