Correct Answer: C

Rationale: The correct action that the nurse should include in the plan for a client receiving hemodialysis is to check the vascular access site for bleeding after dialysis. This is important to prevent complications such as infection or excessive bleeding. Withholding all medications until after dialysis (Choice A) is not necessary unless specific medications need to be avoided due to the dialysis process. Rehydrating with dextrose 5% in water for orthostatic hypotension (Choice B) is not directly related to post-dialysis care. Giving an antibiotic 30 minutes before dialysis (Choice D) is not a standard practice unless there is a specific clinical indication.

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: D

Rationale: A serum creatinine level of 3.0 mg/dL indicates impaired kidney function, which is a concern when prescribing spironolactone as it can further affect renal function. Elevated serum creatinine levels may suggest decreased renal clearance of spironolactone, leading to potential toxicity. Potassium, calcium, and magnesium levels are within normal ranges and not directly related to spironolactone therapy. Therefore, the nurse should report the elevated serum creatinine level to the provider for further evaluation and possible dosage adjustment.

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: Furosemide can cause low potassium levels, and clients should be advised to rise slowly to prevent dizziness.
