Correct Answer: C

Rationale: The correct answer is C: Serum potassium. Spironolactone is a potassium-sparing diuretic, meaning it helps the body retain potassium. Therefore, the nurse should monitor the client's serum potassium levels to prevent hyperkalemia, which can be a potential side effect of spironolactone. Monitoring total bilirubin levels (A) is not specifically required for clients taking spironolactone. Urine ketones (B) are not directly influenced by spironolactone use. Platelet count (D) is not typically monitored in clients taking spironolactone.

Correct Answer: A

Rationale: The correct answer is A because Type 1 diabetes necessitates insulin therapy, whereas Type 2 diabetes is managed with lifestyle modifications and oral agents. Choice B is incorrect because Type 1 diabetes does not use oral agents as a primary treatment. Choice C is incorrect as it describes the pathophysiology of diabetes types rather than their treatments. Choice D is incorrect because Type 2 diabetes management involves more than just insulin and includes lifestyle changes and oral medications.

Correct Answer: C

Rationale: The correct action for the nurse to take is to pour warm water over the client's perineum. This intervention helps stimulate urination after catheter removal by providing warmth and promoting relaxation of the muscles. Assessing for bladder distention after 2 hours (Choice A) is not the initial intervention to facilitate voiding. Encouraging the client to try urinating in a sitting position (Choice B) may be uncomfortable if the client is struggling to void. Restricting the client's fluid intake (Choice D) is not appropriate as it can further exacerbate the issue by concentrating the urine.

Correct Answer: A

Rationale: The correct nursing interventions for a patient with neutropenia include monitoring for signs of infection and administering antibiotics. Neutropenia is characterized by a low neutrophil count, which increases the risk of infections. Monitoring for signs of infection allows for early detection and prompt treatment, while administering antibiotics helps prevent or treat any infections that may occur. Isolating the patient and providing a low-microbial diet (Choice B) are not necessary unless the patient develops an active infection. Monitoring vital signs and avoiding unnecessary invasive procedures (Choice C) are important but do not specifically address the increased infection risk in neutropenic patients. Encouraging the patient to engage in social activities (Choice D) is not appropriate for a neutropenic patient due to the risk of exposure to infectious agents.

Correct Answer: B

Rationale: The correct position for a lumbar puncture is the lateral recumbent position. This position allows the spine to curve naturally, widening the spaces between the vertebrae, making it easier and safer to perform the procedure. Supine with head elevated (Choice A) would not provide the proper positioning for a lumbar puncture as it does not allow for proper access to the lumbar area. Prone with arms at sides (Choice C) would not be suitable as it would not facilitate the procedure. Sitting with back rounded (Choice D) is also incorrect as it does not allow for the proper alignment of the spine needed for a lumbar puncture.
