문제
A 6-year-old child with HIV infection is admitted to the pediatric unit with fever, cough, and difficulty breathing. The child's CD4+ count is 180 cells/mm³. Which nursing intervention should be the priority?
2Place the child in protective isolation and monitor respiratory status closely✓ 정답
3Obtain blood cultures and start broad-spectrum antibiotics
4Encourage increased fluid intake and provide humidified oxygen
해설
Children with HIV and low CD4+ counts (180 cells/mm³) are severely immunocompromised and at high risk for opportunistic infections like PCP. Protective isolation prevents exposure to pathogens, and close respiratory monitoring allows early detection of deterioration. Other interventions are important but secondary to safety.

Core Nursing ExplanationKey Concept Analysis: This question assesses the priority nursing intervention for a severely immunocompromised pediatric patient presenting with respiratory symptoms. The core theme is Infection Control and Airway Management in the context of HIV (Human Immunodeficiency Virus) and Opportunistic Infections. A CD4+ count of 180 cells/mm³ indicates severe immunosuppression (Normal for a child is typically >500 cells/mm³). Fever, cough, and dyspnea are classic signs of Pneumocystis jirovecii pneumonia (PCP), a life-threatening opportunistic infection. The immediate priority is to protect the patient from further harm and closely monitor the primary threat to life: respiratory compromise.
Answer Rationale: Key Point! The priority is safety and prevention of further infection while monitoring for deterioration. Option ②, "Place the child in protective isolation and monitor respiratory status closely," directly addresses both the Risk for Infection and the Impaired Gas Exchange nursing diagnoses. Protective isolation (also called neutropenic precautions) is critical to prevent exposure to new pathogens in a child with a severely weakened immune system. Simultaneous, close monitoring of respiratory status (rate, effort, oxygen saturation, breath sounds) is the top clinical priority to detect early signs of respiratory failure, which is the most immediate threat to life.
Distractor Analysis:
Option ① (Administer antiretroviral medications): While antiretroviral therapy (ART) is the cornerstone of long-term HIV management, it is not the immediate priority for an acute, life-threatening respiratory infection. ART manages the underlying virus but does not treat an active opportunistic infection like PCP. This intervention is important but not the first action.
Option ③ (Obtain blood cultures and start antibiotics): This is a correct medical intervention for a suspected infection, but it is a dependent nursing action (requires a physician's order). The nurse's independent, priority action is to first ensure patient safety (isolation) and establish ongoing assessment (respiratory monitoring) to provide data for those medical decisions. Jumping to procedures before securing the environment and baseline assessment is not the best first step.
Option ④ (Encourage fluids and provide humidified O2): These are supportive measures for respiratory distress. However, administering oxygen is a dependent action. More importantly, before providing any treatment, the nurse must first implement precautions to protect the child and establish a monitoring plan. This option addresses comfort and support but misses the critical safety and assessment components that come first.
Related Concepts: The nursing process dictates that assessment and safety (the first steps of ADPIE) come before implementation of specific treatments. In immunocompromised patients, the risk for infection is a constant, high-priority concern. For pediatric patients, respiratory status is always a top assessment priority due to smaller airways and rapid potential for decompensation.

Key Takeaway
HIV in Pediatrics
Manifests similarly to adults but progression can be faster. Opportunistic infections are a major cause of morbidity/mortality.
CD4+ Count
Marker of immune function. 500). Then, the priority might shift to a full respiratory assessment and supportive care, as the risk for an opportunistic infection is lower.
It might ask for patient education topics. For a child with HIV and a low CD4+, the priority education would be about infection prevention (hand hygiene, avoiding sick contacts, recognizing signs of infection).
임상 시나리오
Nursing Clinical Practice GuideClinical Scenario: You are the nurse receiving 6-year-old "Leo," who is known to have perinatally-acquired HIV. He is lethargic, tachypneic with nasal flaring, and has an SpO2 of 92% on room air. His mother reports he has had a fever and worsening cough for three days.
Nursing Intervention Strategy:
Immediate Action (First 5 minutes):
Don appropriate PPE (gloves, gown, mask as per facility policy for neutropenic precautions).
Escort Leo and his mother directly to a private, negative pressure room if available, or a private room. This is your Key Point! first action.
Perform a focused respiratory assessment: Count respiratory rate, observe work of breathing (retractions, grunting), auscultate lung sounds (often clear initially in PCP, then may have fine crackles), and apply pulse oximetry for continuous monitoring.
Place a "Protective Precautions" sign on the door.
Obtain a full set of vital signs and a more detailed history from the mother.
Notify the physician/provider immediately with your assessment findings, emphasizing the low CD4+ count and respiratory symptoms.
Anticipate and prepare for orders: Chest X-ray, arterial blood gas (ABG), blood cultures, and administration of supplemental oxygen (humidified) and IV antibiotics (likely TMP-SMX).
Comprehensive Care & Education:
Administer medications as ordered, monitoring for adverse effects (e.g., rash, bone marrow suppression with TMP-SMX).
Encourage small, frequent sips of fluids if tolerated to thin secretions.
Provide emotional support to Leo and his family, explaining all procedures in age-appropriate terms.
Educate the family on the purpose of protective isolation: "We're putting Leo in this special room to keep him safe from other germs while his immune system is weak."
Patient Safety and Precautions:
Isolation Compliance: All staff and visitors must perform meticulous hand hygiene before and after entering the room. Visitors should be screened for illness.
Medication Safety: Antiretroviral medications are often complex regimens. Verify the home regimen and ensure no interruptions, but remember treating the acute OI is the immediate focus.
Monitoring: Deterioration can be rapid. Watch for increasing oxygen requirements, fatigue, and signs of respiratory acidosis (headache, confusion, decreased level of consciousness).
Nursing Procedure & Medication FlowProtective Isolation Setup:
1. Assign private room.
2. Place appropriate signage.
3. Ensure dedicated patient care equipment (stethoscope, BP cuff) remains in the room.
4. Instruct on strict hand hygiene for everyone.
5. Limit fresh fruits/flowers (risk of fungal spores).
Medication: Trimethoprim-Sulfamethoxazole (TMP-SMX) IV:
* Action: Bactericidal; inhibits folic acid synthesis in bacteria and Pneumocystis.
* Nursing Considerations:
* Infuse over 60-90 minutes. Monitor for infusion reactions.
* Major Side Effects: Stevens-Johnson syndrome (SJS) - monitor for rash; Bone marrow suppression - monitor CBC; Hyperkalemia - monitor potassium levels.
* Ensure adequate hydration to prevent crystalluria (cloudy urine).
A Word from Your Senior Nurse
"In pediatrics, seeing a child struggle to breathe is one of the most heart-wrenching scenes. Your calm, swift action to create a safe space (isolation) and your sharp eyes on their breathing can make all the difference. Remember, with immunocompromised patients, you are their shield. The isolation room isn't about alienation; it's about creating a fortress against invisible threats. On the NCLEX and in practice, always ask yourself: 'What is the greatest immediate threat to my patient's life or safety?' In this case, it's infection + airway. Address that first, and the rest of the care plan will follow logically. You've got this!"

HIV (Human Immunodeficiency Virus) — A virus that attacks the body's immune system, specifically CD4 cells (T cells), weakening the ability to fight infections and disease.
CD4+ Count — A measure of the number of CD4 T-lymphocytes in a blood sample; the primary indicator of immune function in HIV infection.
Pneumocystis jirovecii Pneumonia — A life-threatening fungal pneumonia and a common opportunistic infection in immunocompromised individuals, especially those with HIV/AIDS and low CD4+ counts.
Protective Isolation (Neutropenic Precautions) — Infection control practices used to protect a patient who is immunocompromised (has a low white blood cell count) from exposure to infectious organisms.
Opportunistic Infection — An infection caused by pathogens that take advantage of a host's weakened immune system (e.g., from HIV, chemotherapy). Examples include PCP, candidiasis, and toxoplasmosis.
