Correct Answer: A

Rationale: The correct answer is to monitor potassium levels. Spironolactone is a potassium-sparing diuretic, which means it helps the body retain potassium and excrete sodium. Monitoring potassium levels closely is essential because spironolactone can cause hyperkalemia (high potassium levels). Sodium levels are not typically affected by spironolactone. Calcium and magnesium levels are also not directly impacted by spironolactone, making choices B, C, and D incorrect.

Correct Answer: D

Rationale: Verifying the blood type with another nurse is critical before starting a blood transfusion to prevent a potentially life-threatening transfusion reaction. This step ensures that the client receives the correct blood product. Administering pre-transfusion medication, ensuring adequate fluid intake, and monitoring vital signs are important steps during the transfusion process, but verifying the blood type is the most crucial step to ensure patient safety.

Correct Answer: B

Rationale: In hyperthyroidism, there is an increase in metabolism, leading to symptoms such as increased appetite, weight loss, and heat intolerance. Therefore, the nurse should expect an increased appetite in a client with hyperthyroidism. Choices A, C, and D are incorrect because decreased heart rate and cold intolerance are more commonly associated with hypothyroidism, while weight gain is not typically seen in hyperthyroidism.

Correct Answer: C

Rationale: The correct answer is C: Pasta with marinara sauce. Clients with renal disease following a low-protein diet should opt for lower-protein options. Pasta with marinara sauce is a suitable choice as it is lower in protein compared to grilled chicken, tofu, or salmon. Grilled chicken, tofu, and salmon are higher in protein content and are not ideal for individuals following a low-protein diet for renal disease as they may strain the kidneys.

Correct Answer: A

Rationale: The correct answer is to evaluate the client's swallowing ability. Osmotic demyelination can cause dysphagia, putting the client at risk for aspiration. Assessing swallowing function is crucial to prevent complications such as aspiration pneumonia. Reorienting the client frequently (Choice B) is more suitable for confusion related to conditions like delirium. Patching one eye (Choice C) is a technique used for diplopia or double vision, not specifically indicated for osmotic demyelination. Performing range of motion exercises (Choice D) may be beneficial for preventing complications of immobility but is not the priority intervention for osmotic demyelination.
