A nurse is reviewing the BUN result of a client who is taking cyclosporine following a kidney transplant. Which of the following laboratory studies should the nurse recognize as another renal function study that should be monitored?

Choice A reason: A client with a sealed radiation implant requires strict precautions and monitoring to prevent radiation exposure to others. Early discharge is unsafe due to ongoing treatment needs, so this client is not suitable, making this incorrect.
Choice B reason: A COPD client with a respiratory rate of 24 breaths/min indicates potential instability, requiring monitoring for exacerbation. Early discharge risks decompensation without ensured stability, so this client is not appropriate, making this incorrect.
Choice C reason: A client receiving heparin for DVT needs continuous anticoagulation and monitoring to prevent embolism. Discharging early risks clotting complications, so this client requires ongoing hospital care, making this incorrect for early discharge.
Choice D reason: A client 1 day post-cholecystectomy, if stable, is often ready for discharge, as this surgery is routine with quick recovery. Freeing this bed supports disaster response, aligning with triage principles, making this the correct choice.

Choice A reason: Restricting fluids to 1,200 mL per day is not indicated post-hernia repair unless specific conditions like heart failure exist. Adequate hydration supports recovery and prevents complications like constipation. This restriction is arbitrary and potentially harmful, making it an incorrect plan component.
Choice B reason: Encouraging deep breathing exercises every 2 hours prevents pulmonary complications like atelectasis or pneumonia, common risks post-hernia repair due to anesthesia and pain-limited breathing. This promotes lung expansion and oxygenation, aligning with evidence-based postoperative care, making it the correct intervention.
Choice C reason: Applying a warm compress to the surgical site is not recommended, as it may increase swelling or risk infection in the early postoperative period. Cool compresses, if needed, reduce edema. This intervention lacks evidence and could harm healing, making it inappropriate.
Choice D reason: Limiting ambulation for 48 hours delays recovery, as early mobility post-hernia repair reduces complications like thromboembolism and promotes healing. Patients are typically encouraged to walk within hours, making this restriction counterproductive and against standard postoperative protocols, thus incorrect.
