A nurse is caring for a client with acute lymphoblastic leukemia (ALL) who has been receiving chemotherapy for 2 weeks. Which assessment finding would be the priority concern requiring immediate nursing intervention?

## 보기

1. Temperature of 101.2°F (38.4°C) with chills and diaphoresis **✔ 정답**
2. Platelet count of 45,000/mm³ with petechiae on the arms
3. Hemoglobin level of 8.2 g/dL with reports of fatigue
4. White blood cell count of 2,500/mm³ with no other symptoms

**정답: 1**

## 해설

Fever with chills and diaphoresis in a neutropenic client indicates potential infection, which is a life-threatening emergency requiring immediate intervention. Other findings (thrombocytopenia, anemia, leukopenia) are concerning but less urgent.

Clinical Context and Priority Setting

This question presents a client with acute lymphoblastic leukemia (ALL) undergoing chemotherapy. The core of the question is recognizing the most life-threatening complication of chemotherapy-induced myelosuppression. While all the assessment findings represent expected or concerning consequences of bone marrow suppression, one finding signals a condition with the highest and most immediate mortality risk if intervention is delayed.

Understanding the Pathophysiology

Cytotoxic chemotherapy targets rapidly dividing cells, which includes not only leukemic blasts but also healthy hematopoietic stem cells in the bone marrow. This leads to pancytopenia. The absolute neutrophil count (ANC) is critically affected because neutrophils have the shortest lifespan in circulation. When the ANC drops below a critical threshold, the body's primary defense against bacterial and fungal organisms is lost. Endogenous flora from the gut and skin can translocate and cause a rapidly progressive, systemic infection. In the absence of neutrophils, the classic signs of inflammation—such as pus formation or localized erythema—may be absent, making fever the single most important and often the only initial sign of a life-threatening infection.

Analysis of Assessment Findings

1.  Temperature of 101.2°F (38.4°C) with chills and diaphoresis

This finding is the priority. In a patient with chemotherapy-induced neutropenia, a single oral temperature of ≥38.3°C (101°F) or a sustained temperature of ≥38.0°C (100.4°F) over one hour defines febrile neutropenia. This is a medical emergency. The presence of chills and diaphoresis strongly suggests the patient is already mounting a systemic inflammatory response to a bloodstream infection (bacteremia). Immediate intervention, including obtaining blood cultures and initiating broad-spectrum intravenous antibiotics within one hour of presentation, is the standard of care to prevent progression to septic shock and death. A nursing risk prediction model for febrile neutropenia highlights that timely recognition and intervention are critical nursing-led actions to reduce mortality [3].

2.  Platelet count of 45,000/mm³ with petechiae on the arms

A platelet count of 45,000/mm³ indicates moderate thrombocytopenia and a risk of bleeding. The presence of petechiae confirms platelet dysfunction. However, the risk of spontaneous, life-threatening hemorrhage (e.g., intracranial) generally becomes a more immediate concern when the platelet count drops below 10,000-20,000/mm³. While this requires careful monitoring and implementation of bleeding precautions, the immediate threat to life is less acute than the potential for overwhelming sepsis signaled by the fever.

3.  Hemoglobin level of 8.2 g/dL with reports of fatigue

This hemoglobin level reflects mild to moderate anemia, which is an expected cumulative effect of chemotherapy. The resulting fatigue is a significant quality-of-life concern and can impair functional status, but it does not represent an immediately life-threatening emergency. The body can physiologically compensate for a gradual decline in hemoglobin through increased cardiac output and shifts in the oxygen-hemoglobin dissociation curve.

4.  White blood cell count of 2,500/mm³ with no other symptoms

This finding indicates leukopenia, which is a precursor to neutropenia. The total white blood cell count alone is not as clinically significant as the absolute neutrophil count (ANC). More importantly, the absence of fever or any infectious symptoms places this patient in a lower-risk category for immediate intervention compared to the febrile patient. The focus here is on neutropenic precautions and vigilant monitoring, not emergency intervention.

Connecting Evidence to Clinical Practice

The rationale for prioritizing fever is strongly supported by the clinical consequences of prolonged and profound myelosuppression. A meta-analysis on treatment duration in acute leukemia highlights that prolonged cytopenias are directly associated with increased infection risks, making the management of febrile episodes a central challenge in leukemia care . The development of standardized management pathways for chemotherapy-induced neutropenia is specifically aimed at preventing the cascade from neutropenia to febrile neutropenia, which leads to dose reductions, treatment delays, and increased mortality . The nursing priority is to intercept this cascade at the earliest sign of decompensation. The assessment finding of a fever with chills is the most critical signal that the patient has transitioned from a state of risk (neutropenia) to a state of active, life-threatening complication (febrile neutropenia). The immediate nursing intervention is not simply to report the temperature, but to initiate the sepsis protocol: obtaining blood cultures from a central line and a peripheral site, administering the first dose of a prescribed broad-spectrum antibiotic, and supporting hemodynamic stability with fluid resuscitation as ordered.References (research sources)

Neutropenic Fever ManagementOncologic Emergency in Chemotherapy Patients
In a neutropenic patient, a single temperature of ≥38.3°C (101°F) or a sustained temperature of ≥38.0°C (100.4°F) over 1 hour is an oncologic emergency.

Immediate intervention includes obtaining blood cultures (peripheral and central line if present) and administering broad-spectrum IV antibiotics within 60 minutes of presentation to prevent septic shock.

CautionClassic signs of infection (pus, erythema, localized warmth) are often absent in severe neutropenia. Fever may be the only initial indicator of a life-threatening infection.

## 핵심 개념

- **Neutropenic Fever** — A single oral temperature ≥38.3°C (101°F) or ≥38.0°C (100.4°F) sustained over 1 hour in a patient with an absolute neutrophil count (ANC)
- **Myelosuppression** — A common side effect of chemotherapy where bone marrow activity is decreased, leading to pancytopenia (anemia, thrombocytopenia, leukopenia).
- **Absolute Neutrophil Count (ANC)** — A measure of the number of neutrophil granulocytes present in the blood, calculated by WBC × (% neutrophils + % bands), used to assess infection risk.
- **Febrile Neutropenia** — Fever in the setting of a critically low neutrophil count, requiring immediate broad-spectrum antibiotic administration and diagnostic workup.
