A client presents to the emergency department with burns covering 20% of their total body surface area. How will the nurse determine that fluid resuscitation in this client has been effective?

Autonomic dysreflexia is a life-threatening condition that occurs in clients with spinal cord injuries at or above T6 due to an exaggerated autonomic response to a noxious stimulus below the level of injury. It is commonly triggered by bladder distention, bowel impaction, or other irritants. This leads to sudden hypertension, pounding headache, bradycardia, and diaphoresis above the level of injury. Immediate identification and removal of the triggering stimulus is the priority to prevent complications such as stroke or seizures.

Rationale:
A. Administering an antihypertensive medication is not the first action because the priority is to identify and eliminate the underlying cause of the autonomic dysreflexia. While medications may be needed if symptoms persist, treating the trigger (often bladder or bowel-related) is the most immediate and effective intervention. Giving medication without removing the stimulus does not resolve the root cause of the crisis.

B. Placing the client in a supine position is incorrect because it can worsen hypertension by increasing venous return and intracranial pressure. The recommended position is to elevate the head of the bed to reduce blood pressure and promote orthostatic pooling of blood in the lower extremities. Positioning alone, however, is not sufficient without addressing the triggering stimulus.

C. Checking the urinary catheter for kinks is the priority action because bladder distention is the most common cause of autonomic dysreflexia. An obstructed catheter can lead to rapid bladder filling, triggering the autonomic response. Immediate assessment and relief of urinary retention help reduce blood pressure and resolve symptoms quickly.

D. Performing digital rectal stimulation is contraindicated as an initial intervention because it may worsen the episode if a bowel impaction is present and has not been properly prepared for disimpaction. Additionally, rectal stimulation can further increase autonomic stimulation and elevate blood pressure. It should only be done after stabilizing the client and addressing more urgent causes such as bladder obstruction.

Post–kidney transplant clients require lifelong immunosuppression to prevent organ rejection. Cyclosporine is commonly used to suppress T-cell activation and reduce the risk of graft rejection. However, it has a narrow therapeutic window and is known for significant nephrotoxicity. Careful monitoring of renal function is essential to detect early signs of toxicity and preserve graft function.

Rationale:
A. Monitoring BUN and creatinine levels regularly is the priority because cyclosporine is highly nephrotoxic and can cause dose-dependent kidney damage. Rising creatinine and BUN levels may indicate impaired renal perfusion or direct tubular toxicity. Early detection allows for dose adjustment or medication changes to prevent irreversible graft injury.

B. Advising the client to consume grapefruit juice is unsafe because grapefruit inhibits cytochrome P450 enzymes, specifically CYP3A4, which metabolizes cyclosporine. This leads to increased drug levels and a higher risk of toxicity, including nephrotoxicity and neurotoxicity. Therefore, grapefruit juice should be strictly avoided rather than encouraged.

C. Instructing the client to take cyclosporine with food to reduce gastrointestinal irritation is not the priority intervention for toxicity prevention. While taking the medication consistently with or without food may improve absorption consistency, food intake does not significantly reduce its toxic effects. The primary concern remains monitoring blood levels and renal function.

D. Encouraging increased fluid intake does not directly prevent cyclosporine toxicity. Although adequate hydration supports kidney perfusion, it does not counteract the drug’s nephrotoxic effects or prevent accumulation in the body. The most effective strategy is ongoing laboratory monitoring to detect early renal impairment.
