Correct Answer: B

Rationale: The correct answer is B: Tyramine. Tyramine can interact with monoamine oxidase inhibitors, leading to hypertensive crises. Folate (choice A) is not contraindicated with monoamine oxidase inhibitors. Potassium (choice C) is an essential mineral and not specifically contraindicated with these medications. Vitamin K (choice D) is not a concern for interactions with monoamine oxidase inhibitors.

Correct Answer: A

Rationale: The correct answer is to discuss the importance of tapering medications when discontinuing medication. Tapering glucocorticoids is crucial to prevent adrenal insufficiency, which can occur if the medication is stopped abruptly. Choice B is incorrect because it focuses on adjustments during stress or infection, not discontinuation. Choice C is unrelated to the management of glucocorticoids. Choice D is important for emergency identification but is not directly related to medication management.

Correct Answer: A

Rationale: The correct answer is A. Roast beef is high in heme iron, which is best absorbed and helps treat iron deficiency anemia. Choices B, C, and D do not contain significant amounts of heme iron or other iron-rich foods that would be beneficial in managing iron deficiency anemia. Cheese pizza, scrambled eggs, bacon, white toast, corn flakes, and whole wheat toast do not provide the necessary heme iron needed to address the client's condition.

Correct Answer: C

Rationale: The correct answer is C because an audible S3 in a client with mitral valve prolapse could indicate heart failure, which requires immediate assessment. Choice A is less urgent as occasional unifocal PVCs are common. Choice B is important but can be addressed after the client with an audible S3. Choice D, a client with pericarditis in normal sinus rhythm, is stable compared to a client with potential heart failure symptoms.

Correct Answer: D

Rationale: The correct answer is Vitamin K. Prolonged antibiotic use can disrupt the gut flora, which is responsible for synthesizing Vitamin K. This disruption can lead to a Vitamin K deficiency and an increased risk of bleeding. Vitamin A, B6, and C deficiencies are not typically associated with prolonged antibiotic use.
