해설
Children with Hodgkin's disease receiving chemotherapy are severely immunocompromised due to the disease process and treatment effects. Preventing infection is the top nursing priority.
Chemotherapy drugs destroy rapidly dividing cells, including healthy white blood cells essential for immune function. This leads to neutropenia, severely impairing the child's ability to fight infection. Neutropenia is defined as an absolute neutrophil count below 1,500/μL, with counts below 500/μL posing a risk for serious infection.
Strict hand hygiene is the single most effective measure to prevent healthcare-associated infections. All healthcare staff, family members, and visitors must perform thorough hand hygiene before and after patient contact. Protective isolation precautions include restricting visitors, screening for signs of illness, using personal protective equipment when necessary, and maintaining a clean environment.
The immunosuppressed state of pediatric oncology patients makes them vulnerable to opportunistic infections that typically do not affect healthy children. Common pathogens include bacteria, viruses, fungi, and protozoa. Even minor infections can rapidly progress to life-threatening sepsis in these patients.
Nursing interventions should focus on creating barriers to infection transmission while maintaining the child's developmental and psychosocial needs. This includes educating families on infection prevention measures, monitoring for early signs of infection, and implementing appropriate isolation precautions based on the child's neutrophil count and institutional protocols.
Correct Answer 1. Implement strict hand hygiene and use protective isolation precautions
Rationale
For a pediatric patient with Hodgkin's disease undergoing chemotherapy, the most critical nursing intervention to prevent infection is the implementation of strict hand hygiene and protective isolation precautions. Chemotherapy induces bone marrow suppression, leading to a state of neutropenia, typically defined as an absolute neutrophil count (ANC) below 1,500 cells/μL. Neutrophils are the body's primary defense against bacterial and fungal infections; therefore, a deficiency dramatically increases the risk of life-threatening systemic infection from both exogenous and endogenous sources [1].
The evidence-based approach to managing neutropenic patients centers on rigorous infection control as a foundational element of clinical management. This involves a multi-faceted strategy where strict hand hygiene is the single most effective measure to prevent the transmission of pathogens. Protective isolation precautions build upon this by controlling the patient's environment to minimize exposure to opportunistic pathogens, such as Aspergillus spores, which can be fatal in an immunocompromised host [1]. This principle is supported by research evaluating structured nursing interventions, where a personalized nursing pathway that emphasized comprehensive infection prevention measures—including environmental management and strict aseptic techniques—was applied to reduce hospital-acquired infections in hematology patients [2].
Analysis of Incorrect Options
2. Encourage the child to participate in group activities with other patients
This intervention is contraindicated during the nadir period post-chemotherapy. Group activities increase the child's exposure to potential pathogens from other individuals, including hospital staff and visitors, significantly elevating the risk of infection when neutrophil counts are critically low. The priority is source control and minimizing exposure, which is the opposite of encouraging group gatherings [1].
3. Allow fresh flowers and plants in the patient's room for emotional support
While psychosocial support is a vital component of holistic care for oncology patients, fresh flowers and plants are strictly prohibited in the rooms of neutropenic patients. Standing water in plant vases and the soil itself serve as reservoirs for gram-negative bacteria and fungi, particularly Aspergillus species. Inhalation of fungal spores from these sources can lead to invasive pulmonary aspergillosis, a severe and often fatal complication in a profoundly neutropenic host. Emotional support must be provided through alternative, safe means [1].
4. Maintain the child's regular vaccination schedule during treatment
Maintaining a regular vaccination schedule is not safe during active chemotherapy. Live attenuated vaccines (e.g., MMR, varicella, intranasal influenza) are absolutely contraindicated in immunocompromised patients due to the risk of causing an uncontrolled, disseminated infection from the vaccine strain itself. While inactivated vaccines may be given, their efficacy is significantly reduced during immunosuppression, and they do not take precedence over the immediate, critical need for infection prevention through environmental and behavioral controls [1].

Neutropenic Precautions in Pediatric ChemotherapyProtecting the Immunocompromised Child from Infection
The primary goal for a child with an absolute neutrophil count (ANC) below 1,500 cells/μL is preventing infection. The single most effective intervention is strict hand hygiene for all staff, visitors, and the patient.
Implement protective isolation precautions. This includes a private room with positive-pressure airflow and HEPA filtration to minimize exposure to airborne fungal spores like Aspergillus.
Caution
Absolutely no fresh flowers, plants, or raw foods. Avoid rectal procedures and live vaccines. Any fever of 38.0°C (100.4°F) or higher is a medical emergency requiring immediate blood cultures and broad-spectrum antibiotics.
