Correct Answer: A

Rationale: Administering analgesics as prescribed is the appropriate intervention for managing perineal pain in a postpartum client. Analgesics help to alleviate discomfort and promote the client's recovery. Applying a warm compress (choice B) may provide some relief, but it does not address the pain as effectively as analgesics. Encouraging ambulation (choice C) and positioning the client with the head elevated (choice D) are not directly related to addressing perineal pain.

Correct Answer: A

Rationale: The correct answer is A: Creatinine. Gentamicin can cause nephrotoxicity, leading to impaired kidney function. Monitoring creatinine levels helps the nurse detect any potential kidney damage. Choice B, Aspartate aminotransferase (AST), is not typically affected by gentamicin. Choice C, White blood cell count, is not directly related to gentamicin adverse effects. Choice D, Serum glucose, is not specifically monitored for gentamicin adverse effects.

Correct Answer: C

Rationale: The correct position for a client immediately postoperative following a hip arthroplasty is the lateral position with an abduction pillow between the legs. This position helps prevent dislocation of the hip prosthesis and maintains proper alignment of the hip joint. Supine position with legs extended (Choice A) may put stress on the hip joint, Semi-Fowler's position with legs bent (Choice B) may not provide adequate support and alignment, and prone position with legs elevated (Choice D) is not recommended after hip arthroplasty as it can compromise the surgical site and increase the risk of complications.

Correct Answer: C

Rationale: The correct answer is C. Levothyroxine is a lifelong medication for clients with hypothyroidism, and it should be taken as prescribed. Choice A is incorrect because levothyroxine should be taken on an empty stomach. Choice B is incorrect because levothyroxine is usually taken in the morning on an empty stomach. Choice D is incorrect because stopping the medication abruptly can have adverse effects on thyroid function.

Correct Answer: C

Rationale: The correct action the nurse should include in the plan of care for a client receiving hemodialysis is to check the vascular access site for bleeding after dialysis. This is crucial to detect any bleeding complications and ensure prompt intervention if necessary. Withholding all medications until after dialysis (Choice A) is not appropriate as some medications may need to be administered during dialysis. Rehydrating with dextrose 5% in water for orthostatic hypotension (Choice B) is not directly related to the immediate post-dialysis care. Giving an antibiotic 30 minutes before dialysis (Choice D) is not recommended as timing of medication administration should be based on the specific antibiotic and its pharmacokinetics.
