Correct Answer: B

Rationale: The correct action for the nurse to take when preparing to perform postmortem care is to remove the client's IV lines. This step is essential to help maintain the dignity and appearance of the body. Placing the client's dentures in a labeled container (Choice A) is not a priority during postmortem care as the focus is on the body's preparation. While positioning the body in a semi-fowler's position (Choice C) or lowering the client's head of the bed (Choice D) are common practices for living clients to prevent aspiration, they are not necessary after death. Therefore, the immediate action of removing IV lines is most appropriate in this situation.

Correct Answer: C

Rationale: The correct action for the nurse to take is to limit IV exposure to light. Nitroprusside is light-sensitive, and exposure to light can lead to its degradation, potentially reducing its efficacy in treating severe hypertension. Keeping calcium gluconate at the bedside (Choice A) is not directly related to managing nitroprusside infusion. While monitoring blood pressure every 2 hours (Choice B) is important in managing hypertension, it is not the immediate action required to ensure medication efficacy. Attaching an inline filter to the IV tubing (Choice D) may help filter particles but does not address the critical concern of light sensitivity associated with nitroprusside administration.

Correct Answer: B

Rationale: Cheddar cheese is a rich source of calcium and should be recommended to clients with osteoporosis. While broccoli and almonds also contain calcium, cheddar cheese provides a higher amount per serving. Fortified orange juice may contain added calcium, but it is not as concentrated a source as cheddar cheese. Therefore, the best choice for a client with osteoporosis seeking a high calcium food is cheddar cheese.

Correct Answer: B

Rationale: The correct action for the nurse to take is to administer sodium polystyrene sulfonate. This medication promotes potassium excretion and helps lower serum potassium levels in clients with hyperkalemia, which is indicated by a high potassium level. Sodium bicarbonate (choice A) is not used to treat hyperkalemia. Calcium gluconate (choice C) and calcium carbonate (choice D) are used to manage hyperkalemia by stabilizing cell membranes but are not the initial treatment choice for lowering potassium levels.
