A nurse is caring for a 38-year-old client who received a kidney transplant 3 months ago and is taking tacrolimus, mycophenolate, and prednisone. Which nursing intervention is the highest priority to prevent transplant rejection?

Preventing infection is highest priority because immunosuppressive therapy increases infection risk, which can trigger rejection. Other interventions (e.g., medication adherence) are important but secondary.

Understanding the Priority: Infection vs. Rejection in the Stable Transplant Recipient

This question tests your ability to differentiate immediate life-threatening risks in a post-kidney transplant client. While preventing organ rejection is the ultimate goal of transplantation, the pharmacodynamics of the maintenance immunosuppressive regimen create a more pressing daily threat: infection. The client is 6 months post-transplant and on a triple-drug regimen consisting of tacrolimus (a calcineurin inhibitor), mycophenolate (an antimetabolite), and prednisone (a corticosteroid). This combination induces a profound state of generalized immunosuppression, particularly impairing T-cell and B-cell function, which significantly heightens susceptibility to bacterial, viral, and fungal pathogens.

Analysis of the Correct Answer (Option 1)

Monitoring for signs and symptoms of infection and teaching proper hand hygiene is the highest priority. The provided evidence underscores that immunosuppressed patient populations, such as those in intensive care or post-transplant, are exceptionally vulnerable to infections, including those caused by multi-drug-resistant organisms (MDROs) ^[3]. The systematic review protocol on neutropenic diets highlights the substantial early infectious risk associated with immunosuppression, which extends beyond the immediate post-operative period . In the outpatient setting, the client's primary defense against environmental pathogens is meticulous hand hygiene. A seemingly minor infection can rapidly escalate to sepsis in an immunocompromised host because the blunted immune response may mask classic signs like fever or purulent drainage, delaying diagnosis and treatment.

Analysis of the Incorrect Answers

Option 2: Encouraging a high-protein diet is beneficial for overall wound healing and nutritional status, but it does not directly prevent transplant rejection or address the most immediate threat to life. Furthermore, dietary modifications must be carefully considered, as the meta-analysis protocol notes that restrictive diets like the neutropenic diet can sometimes negatively impact nutritional intake and the gut microbiota, which plays a role in immune recovery . The priority is not macronutrient adjustment but preventing pathogen entry.

Option 3: Assessing for signs of acute rejection, such as decreased urine output and an elevated creatinine level, is a critical nursing function. However, at 6 months post-transplant with a stable clinical presentation for a routine follow-up, the risk of acute rejection is generally lower than the constant, daily risk of opportunistic infection. This assessment is important but does not constitute the highest priority intervention for preventing a complication; it is a surveillance measure for detecting a complication that may or may not be occurring.

Option 4: Educating the client about strict adherence to the immunosuppressive regimen is fundamental to preventing late graft rejection. While non-adherence is a leading cause of late rejection, the question asks for the highest priority nursing intervention. In a stable client, reinforcing medication education is a standard part of the visit. However, the immediate action of screening for an active, life-threatening infection and proactively teaching a preventive technique like hand hygiene takes precedence. A severe infection can not only cause sepsis but can also trigger a cytokine storm that may precipitate acute rejection, making infection prevention a dual-purpose intervention. The perioperative nursing review confirms that nursing-driven surveillance and education are cornerstones of preventing healthcare-associated infections, a principle that translates directly to protecting the immunocompromised transplant recipient in the community .
