Correct Answer: A

Rationale: The correct answer is A, Hyperlipidemia. Hyperlipidemia, characterized by high levels of lipids in the blood, is a well-established risk factor for the development of angina. Elevated lipid levels can lead to atherosclerosis, which narrows the arteries supplying the heart muscle with oxygenated blood, increasing the risk of angina. Choices B, C, and D are incorrect because COPD, seizure disorder, and hyponatremia are not directly associated with an increased risk of angina.

Correct Answer: B

Rationale: Applying a fetal heart rate monitor is the priority action in this scenario as it helps assess the well-being of the fetus during labor. This monitoring is crucial to detect any signs of fetal distress and guide interventions. Inserting an indwelling urinary catheter (Choice A) is not a priority at this time unless there are specific indications. Initiating fundal massage (Choice C) is not necessary in this situation as the focus should be on fetal assessment. Initiating an oxytocin IV infusion (Choice D) is not indicated until the stage of labor and the progress of labor are determined.

Correct Answer: B

Rationale: The correct answer is B. When taking ferrous sulfate, clients should expect their stools to turn black, which is a normal side effect due to the iron content. Choice A is incorrect because ferrous sulfate should not be taken with milk as it can decrease its absorption. Choice C is incorrect because vitamin C-rich foods like oranges can actually enhance the absorption of iron. Choice D is incorrect because ferrous sulfate is usually recommended to be taken on an empty stomach for better absorption.

Correct Answer: C

Rationale: The correct answer is C because propylthiouracil (PTU) can increase the risk of infection. Therefore, the client should be aware that this medication may compromise their immune system, making them more susceptible to infections. Reporting any signs of infection promptly to the provider is crucial for timely intervention and management. Choices A, B, and D are incorrect because reporting a sore throat, assuming lifelong medication intake, or experiencing decreased appetite are not directly related to the medication's side effects or risks.

Correct Answer: C

Rationale: The correct instruction for a client prescribed metoprolol is to monitor their heart rate before taking the medication. Metoprolol is a beta-blocker that can cause bradycardia (slow heart rate), so it is essential for clients to check their heart rate before each dose. Choice A is incorrect because abruptly stopping metoprolol can lead to adverse effects, so it should not be discontinued suddenly. Choice B is incorrect because there is no specific recommendation to take metoprolol at night to reduce falls. Choice D is incorrect because grapefruit juice can interact with metoprolol, affecting its absorption, and should be avoided.
