Which is most important for the nurse to implement for a patient after renal transplant surgery?

The most important action for a nurse to implement after a renal transplant surgery is to remove the indwelling catheter as soon as possible. In the postoperative context, urinary catheters are often used to facilitate urine drainage and monitor output. However, they can significantly increase the risk of urinary tract infections (UTIs), which is a concerning complication in transplant patients who are already immunocompromised due to their use of immunosuppressive medications to prevent organ rejection.

Removing the indwelling catheter promptly helps reduce this risk by minimizing the invasive access to the urinary tract, promoting normal voiding, and allowing for better bladder function. It's critical to monitor the patient's urinary output, but this can generally be done through other means once the catheter is out, such as using portable urinals or bedpans.

In contrast, flushing a peritoneal dialysis catheter, monitoring magnesium levels, or placing a patient on contact isolation may have their own importance based on individual patient needs or underlying conditions, but they do not hold the same immediacy or relevance following a renal transplant surgery as the management of indwelling catheters does.
