## 문제

A nurse is caring for a client receiving chemotherapy who develops severe neutropenia with an absolute neutrophil count (ANC) of 450 cells/mm³. Which nursing intervention should be the highest priority?

## 보기

1. Place the client in a private room and initiate neutropenic precautions immediately **✔ 정답**
2. Administer the prescribed antiemetic medication to prevent nausea and vomiting
3. Encourage increased fluid intake to prevent dehydration from chemotherapy
4. Monitor the client's platelet count for signs of thrombocytopenia

**정답: 1**

## 해설

Severe neutropenia (ANC < 500 cells/mm³) requires immediate neutropenic precautions, including private room placement, to prevent life-threatening infections. Other interventions are important but secondary to infection prevention.

Understanding the Priority: Infection Risk in Severe Neutropenia

The client's absolute neutrophil count (ANC) of 450 cells/mm³ defines a state of severe neutropenia. Neutrophils are the primary defense against bacterial and fungal infections. When the ANC falls below 500 cells/mm³, the risk of life-threatening infection escalates dramatically because the body has lost its ability to mount an effective inflammatory response [1]. In this immunocompromised state, a typical sign of infection like pus or localized redness may be absent; the only indicator of a severe infection might be fever, which constitutes a febrile neutropenia (FN) emergency .

Why Neutropenic Precautions Are the Highest Priority

Placing the client in a private room and initiating neutropenic precautions is the highest priority because it directly addresses the most immediate and lethal threat: the acquisition of a healthcare-associated or environmental infection. Evidence-based nursing strategies for neutropenic patients emphasize strict infection control as a foundational element of clinical management to prevent serious complications and worsening treatment outcomes [1]. A structured nursing intervention approach that prioritizes protective isolation has been shown to significantly reduce infection rates and complication-related morbidity in immunocompromised patients undergoing intensive treatment [3]. The core principle is to create a protective environment that minimizes the client's exposure to pathogens, including bacteria, viruses, and fungi, when their immune system is at its nadir.

Analysis of Other Options

While the other interventions are important aspects of care for a client receiving chemotherapy, they do not address the most immediate, life-threatening risk.

- Administering antiemetics (Option 2) is important for comfort and preventing fluid/electrolyte imbalances, but nausea and vomiting are not immediately life-threatening in the same way a fulminant infection is for a severely neutropenic client.

- Encouraging fluid intake (Option 3) is a supportive measure to manage chemotherapy side effects, but it is a lower priority than establishing a protective environment against a lethal infectious threat.

- Monitoring platelet count (Option 4) is crucial for assessing bleeding risk related to thrombocytopenia, another chemotherapy side effect. However, the client's presented critical lab value is the ANC, which signals an imminent risk of infection. Infection prevention takes precedence as the first line of defense.

Clinical Decision-Making and Risk Stratification

The urgency is underscored by the fact that FN is one of the most serious yet potentially preventable complications of systemic chemotherapy . A proactive nursing-led approach to risk stratification and immediate implementation of preventive actions, such as initiating neutropenic precautions, is essential. This intervention is not merely a passive placement but an active, multifaceted nursing strategy that includes strict hand hygiene, restriction of visitors who are ill, avoidance of fresh flowers and standing water, and meticulous client monitoring for subtle signs of infection. A structured oncology nursing intervention program focusing on such early assessment and supportive care has been shown to effectively manage chemotherapy-related toxicities and reduce hospital readmissions . Therefore, the nurse's immediate priority is to protect the client from the highest-risk complication by controlling their environment.References (research sources)

## 임상 시나리오

Managing Severe NeutropeniaImmediate Infection Prevention Protocols
An ANC below 500 cells/mm³ constitutes severe neutropenia, placing the patient at extreme risk for life-threatening infections. The highest priority is immediate placement in a private room with strict protective isolation.

Monitor for febrile neutropenia, which is a single temperature of ≥38.3°C (101°F). Classic signs of infection like pus or redness are often absent; fever may be the only indicator of sepsis.

CautionDo not delay isolation for comfort measures. Ensure no fresh flowers, raw fruits/vegetables, or standing water are in the room. Immediate blood cultures and broad-spectrum antibiotics are required if fever develops.

## 핵심 개념

- **Severe Neutropenia** — An absolute neutrophil count (ANC) less than 500 cells/mm³, indicating a critically high risk for life-threatening infections.
- **Febrile Neutropenia** — A medical emergency defined by a single oral temperature of ≥38.3°C (101°F) or a sustained temperature of ≥38°C (100.4°F) over 1 hour in a neutropenic patient.
- **Neutropenic Precautions** — Protective isolation protocols including a private room, strict hand hygiene, avoidance of fresh flowers/raw foods, and visitor screening to minimize infection risk.
- **Absolute Neutrophil Count (ANC)** — Calculated as WBC × (% neutrophils + % bands); a key indicator of a patient's ability to fight bacterial and fungal infections.
