해설
During neutropenia, the child's immune system is severely compromised, making infection prevention the highest priority. Strict hand hygiene and protective isolation are fundamental interventions to reduce exposure to pathogens.
In pediatric patients receiving chemotherapy for Hodgkin lymphoma, neutropenia is one of the fatal side effects. Neutropenia refers to a condition where the absolute neutrophil count (ANC) drops to 1,500/mm³ or below, and when it falls below 500/mm³, the risk of life-threatening infection increases dramatically.
Since neutrophils are the body's primary defense cells against bacterial and fungal infections, infection prevention becomes the most important nursing goal during neutropenia. Strict hand hygiene and protective isolation measures are the most critical nursing interventions.
Hand hygiene is the single most effective method for preventing healthcare-associated infections. Since hands are the main vehicle for transmitting pathogens, all healthcare staff, family members, and visitors must perform thorough hand hygiene before and after patient contact. Protective isolation includes using a private room, restricting visitors, allowing only healthy visitors, wearing personal protective equipment when necessary, and maintaining a clean environment.
Additional nursing interventions include monitoring for early signs of infection (fever may be the only initial symptom), assessing for systemic infection signs, maintaining skin integrity, meticulous oral care, providing adequate nutrition while avoiding high-risk foods, and family education. In neutropenic patients, sepsis can progress rapidly without an appropriate immune response, so early detection and prompt treatment are crucial.
Understanding Neutropenia in Pediatric Chemotherapy
Neutropenia, defined as an absolute neutrophil count (ANC) below 1,500 cells/μL, is a common and serious consequence of chemotherapy for conditions like Hodgkin's lymphoma . Neutrophils are the body's primary defense against bacterial and fungal infections. During the neutropenic phase, a child's immune system is profoundly compromised, making even normal body flora or common environmental pathogens capable of causing life-threatening sepsis. The primary goal of nursing care shifts to protecting the patient from potential sources of infection until their bone marrow recovers and the ANC rises to a safer level.
Analysis of Correct and Incorrect Options
The correct answer is to implement strict hand hygiene and use protective isolation precautions. This intervention is the cornerstone of infection prevention for a neutropenic patient. Evidence-based nursing strategies for this population emphasize strict infection control as a primary domain of clinical management . Hand hygiene is the single most effective measure to interrupt the transmission of pathogens. Protective isolation, which includes measures such as a private room, limiting exposure to individuals with contagious illnesses, and possibly positive-pressure airflow, creates a physical barrier to reduce the patient's exposure to environmental microbes.
The other options are incorrect because they introduce significant infection risks or are not universally recommended first-line nursing actions:
- Encouraging fresh fruits and vegetables is contraindicated. These foods can harbor bacteria and fungi (e.g., Pseudomonas, Aspergillus) that are harmless to an immunocompetent person but can cause overwhelming infection in a neutropenic patient. A neutropenic diet, which typically excludes fresh, uncooked produce, is often implemented to reduce the risk of foodborne sepsis, although its overall efficacy on mortality remains under investigation [1].
- Allowing unrestricted visitation is unsafe. While psychosocial support is critical for a child's well-being, it must be balanced with safety. Visitors, even those who are asymptomatic, can carry transmissible viruses. Nursing strategies must carefully screen and limit visitors to protect the patient, making free visitation an unacceptable practice during the nadir of neutropenia .
- Administering prophylactic antibiotics is not a standard nursing-initiated intervention for all neutropenic patients. Current pediatric oncology guidelines do not recommend routine antibacterial prophylaxis for all children receiving chemotherapy . The decision to use prophylaxis is a complex medical one, reserved for specific high-risk scenarios and guided by local resistance patterns and antibiotic stewardship principles to prevent the emergence of multidrug-resistant organisms . A nurse's independent role is to monitor for signs of infection and implement infection prevention measures, not to initiate prophylaxis.

Neutropenic Precautions in Pediatric ChemotherapyProtecting the Immunocompromised Child from Infection
The cornerstone of care is strict hand hygiene and protective isolation. This creates a physical barrier against pathogens when the absolute neutrophil count (ANC) is critically low, often below 500 cells/μL.
Implement a low-microbial diet by excluding fresh fruits, raw vegetables, and unpasteurized products. Ensure all visitors are screened for illness and perform hand hygiene before entering the private, positive-pressure room.
Caution
A single fever of 38.0°C (100.4°F) or higher in a neutropenic patient is a medical emergency requiring immediate blood cultures and broad-spectrum antibiotics. Do not delay notification.
