A 7-year-old child with acute lymphoblastic leukemia (ALL) is receiving chemotherapy and has developed severe neutropenia with an absolute neutrophil count (ANC) of 200/mm³. The child develops a fever of 101.5°F (38.6°C). Which nursing intervention should be the highest priority?

## 보기

1. Administer acetaminophen to reduce the fever and monitor temperature every 2 hours
2. Obtain blood cultures from all lumens of the central venous catheter and peripheral sites
3. Place the child in protective isolation and restrict all visitors except immediate family
4. Immediately notify the oncologist and prepare for prompt administration of broad-spectrum antibiotic **✔ 정답**

**정답: 4**

## 해설

Febrile neutropenia in pediatric oncology patients is a medical emergency requiring immediate intervention. The combination of fever and severe neutropenia (ANC < 500/mm³) indicates high risk for sepsis, necessitating prompt antibiotic administration. Other options are supportive but not emergent priorities.

Understanding Febrile Neutropenia in Pediatric Oncology

In a child undergoing chemotherapy for acute lymphoblastic leukemia (ALL), an absolute neutrophil count (ANC) of 200/mm³ represents severe neutropenia. Neutrophils are the body's primary defense against bacterial and fungal infections. With a count this low, the child has virtually no innate immune capability to contain an infection. A fever of 101.5°F (38.6°C) in this context is a medical emergency defined as febrile neutropenia (FN). The fever is often the only initial sign of a rapidly progressing, life-threatening bloodstream infection because the body cannot mount a typical inflammatory response (pus, swelling, localized pain).

Why Immediate Antibiotic Administration is the Priority

The highest priority intervention is to immediately notify the oncologist and prepare for the prompt administration of broad-spectrum antibiotics. The rationale is rooted in the pathophysiology of sepsis and the time-dependent nature of effective treatment. In a profoundly neutropenic host, bacteria from the gut or a central venous catheter entry site can translocate into the bloodstream and multiply unchecked. Without neutrophils to phagocytize the pathogens, the infection can progress to septic shock and death within hours. The clinical standard, supported by quality improvement initiatives, is to administer empiric broad-spectrum antibiotics within 60 minutes of documented fever [2]. Delays beyond this "golden hour" are directly associated with increased mortality. A comparative analysis of pediatric FN treatment protocols demonstrated that adapting standard operating procedures to specifically reduce the time-to-antibiotic (TTA) is a critical factor in improving patient prognosis [1]. Therefore, every nursing action must be streamlined to achieve this goal, making the preparation for antibiotic infusion the most urgent task.

Analysis of Other Options

While the other interventions are important components of care, they are secondary to the initiation of antibiotic therapy. The rationale for their lower priority is as follows:

Option 1: Administer acetaminophen. Administering an antipyretic like acetaminophen can mask a new or worsening fever, which is a critical clinical sign used to monitor the patient's response to antibiotics and the evolution of the infection. Furthermore, it does nothing to treat the underlying infectious cause and introduces a non-essential delay to definitive therapy. Temperature monitoring is important but is a monitoring activity, not a therapeutic intervention.

Option 2: Obtain blood cultures. Obtaining blood cultures from all lumens of a central venous catheter and a peripheral site is a standard and essential diagnostic step before starting antibiotics. However, it is a sequential step that should be performed rapidly and efficiently in preparation for antibiotic administration, not as an end in itself. The goal is to get cultures and then immediately hang the antibiotic. The culture procurement process should never delay the start of the first antibiotic dose beyond the 60-minute target [2].

Option 3: Place the child in protective isolation. Placing the child in protective (reverse) isolation is a cornerstone of infection prevention for neutropenic patients, as outlined in evidence-based nursing strategies for clinical management . This protects the child from exposure to new pathogens from visitors or staff. However, this is an environmental safety measure. The immediate threat is the infection that is already present and causing the fever. Addressing the existing, life-threatening infection with antibiotics takes absolute priority over preventing a new one.

Clinical Reasoning and Nursing Synthesis

The nurse's clinical judgment must synthesize the pathophysiological urgency with the evidence-based standard of care. The sequence of nursing actions for a febrile neutropenic patient is critical: recognize the emergency, notify the provider, obtain cultures swiftly, and administer the prescribed broad-spectrum antibiotic within 60 minutes. The evidence shows that many hospitals fail to meet this benchmark despite its known benefits, making the nurse's role as a patient advocate and efficient coordinator of care paramount [2]. The holistic framework for neutropenic care confirms that strict infection control and clinical management are foundational, but during an acute FN event, the clinical management domain—specifically the rapid delivery of targeted drug therapy—is the immediate priority . The nurse must prepare the infusion, verify the order, and be ready to administer the antibiotic as soon as it arrives, understanding that each minute of delay increases the risk of mortality from overwhelming sepsis [1].
