A nurse is caring for a client who received a kidney transplant 2 years ago. Which assessment finding would be the MOST concerning and require immediate intervention?

## 보기

1. Blood pressure of 150/90 mmHg
2. Serum creatinine level of 1.8 mg/dL
3. Temperature of 101.2°F (38.4°C) with chills **✔ 정답**
4. Weight gain of 3 pounds over the past week

**정답: 3**

## 해설

Fever with chills in an immunosuppressed transplant patient indicates potential infection, which is life-threatening and requires immediate intervention. Other findings like hypertension, mild creatinine elevation, or weight gain are less urgent.

Understanding the Priority: Infection in the Immunocompromised Host

This question requires you to apply the nursing process and prioritize care based on the most life-threatening condition. The client is a kidney transplant recipient, which means they are on lifelong immunosuppressive therapy to prevent organ rejection. While all the listed assessment findings are abnormal and concerning, you must identify which one signals a potential emergency requiring immediate intervention.

Let’s analyze the options through the lens of pathophysiology and the clinical risks specific to solid organ transplant recipients.

Analysis of Options

Option 1: Blood pressure of 150/90 mmHg

Hypertension is an extremely common finding in kidney transplant recipients, often resulting from the effects of immunosuppressant medications like calcineurin inhibitors (e.g., tacrolimus, cyclosporine) and corticosteroids. While a blood pressure of 150/90 mmHg requires ongoing management and medication adjustment to protect the graft and cardiovascular system, it represents a chronic, not acutely life-threatening, issue. This is an important but non-urgent finding that can be addressed through routine clinical follow-up.

Option 2: Serum creatinine level of 1.8 mg/dL

An elevated serum creatinine is a critical marker for kidney function and can indicate acute rejection, calcineurin inhibitor toxicity, or dehydration. In a transplant recipient, this finding is highly concerning and demands prompt investigation. However, it is a biochemical marker that requires diagnostic workup (e.g., renal ultrasound, biopsy, medication level checks) rather than an immediate bedside intervention. The process of diagnosing the cause of a creatinine rise, while urgent, does not carry the same minute-to-minute threat as a systemic infection.

Option 3: Temperature of 101.2°F (38.4°C) with chills

This is the most concerning finding. Fever and rigors (chills) in an immunosuppressed transplant recipient are a medical emergency until proven otherwise. The immunosuppressive medications blunt the normal inflammatory response, meaning a seemingly mild fever can be the only initial sign of a rapidly progressing, life-threatening infection. The presence of chills is particularly ominous, as it strongly suggests bacteremia, viremia, or fungemia. The referenced case reports powerfully illustrate this danger. One report describes a patient who developed a drug-resistant tuberculosis infection post-transplant, highlighting the diagnostic challenges and severe consequences of infections in this population [2]. Another case details a renal transplant recipient who presented with a heart failure exacerbation that was ultimately triggered by Cytomegalovirus (CMV) viremia, demonstrating how systemic infections can present with atypical, severe manifestations [4]. Immediate intervention—obtaining blood cultures, initiating empiric broad-spectrum antibiotics/antivirals, and notifying the transplant team—is required to prevent sepsis and death.

Option 4: Weight gain of 3 pounds over the past week

A rapid weight gain of 3 pounds (approximately 1.4 kg) in a week is a classic sign of fluid retention. In a kidney transplant patient, this could indicate worsening graft function, heart failure, or medication side effects. While this finding necessitates a thorough assessment (lung sounds, edema, intake and output) and medical follow-up, it does not represent the same level of immediate danger as a systemic infection. Fluid overload is a process that develops over days and can be managed with diuretics and fluid restriction, whereas sepsis from an untreated infection can be fatal within hours.

Synthesis and Clinical Reasoning

The core of this question is the prioritization framework of airway, breathing, and circulation (ABCs) combined with the unique vulnerability of the transplant population. While all options are abnormal, only a fever with chills points directly to a systemic process—sepsis—that can cause rapid hemodynamic instability and death. The case reports in the provided literature reinforce that infections in these patients are often atypical, aggressive, and caused by opportunistic pathogens like CMV or drug-resistant bacteria [2, 4]. The long-term immunosuppression that prevents graft rejection simultaneously cripples the body's defense system, making a fever the single most important vital sign abnormality to act upon immediately.References (research sources)

## 임상 시나리오

Post-Transplant Fever: Emergency TriageInfection is a top priority in the immunosuppressed patient
In any solid organ transplant recipient, a new fever (e.g., temperature of 101.2°F / 38.4°C) with chills is a medical emergency until proven otherwise. This presentation is highly suspicious for sepsis due to their pharmacologically suppressed immune system.

Immediate interventions include obtaining blood cultures, initiating a septic workup (urinalysis, chest X-ray), and notifying the transplant team. Do not delay care to manage less acute issues like mild hypertension or gradual weight gain.

CautionA low threshold for suspicion is critical; a seemingly minor temperature elevation can rapidly progress to septic shock in an immunocompromised host. Classic signs of infection may be masked.

## 핵심 개념

- **Immunosuppression** — A state of reduced immune system function, often drug-induced in transplant recipients to prevent organ rejection, which increases susceptibility to severe infections.
- **Calcineurin Inhibitors** — A class of immunosuppressant drugs (e.g., tacrolimus, cyclosporine) that are nephrotoxic and can cause hypertension; they inhibit T-cell activation.
- **Acute Rejection** — An immune response by the recipient's body against the transplanted organ, often indicated by rising serum creatinine levels in kidney transplants.
- **Systemic Inflammatory Response Syndrome (SIRS)** — A clinical syndrome characterized by fever, tachycardia, and tachypnea, which can be triggered by infection (sepsis) and is a medical emergency.
