## 문제

A 4-year-old child with pneumonia is admitted to the pediatric unit. The child has a temperature of 102.8°F (39.3°C), respiratory rate of 40 breaths/minute, and oxygen saturation of 88% on room air. Which nursing intervention should be the priority?

## 보기

1. Administer acetaminophen for fever reduction
2. Provide emotional support to the anxious parents
3. Encourage increased fluid intake to prevent dehydration
4. Initiate oxygen therapy to improve oxygenation **✔ 정답**

**정답: 4**

## 해설

Priority is oxygen therapy to address hypoxemia (SpO2 88%), which is life-threatening. Fever reduction, parental support, and hydration are secondary interventions.

Priority Intervention for a Child with Pneumonia and Hypoxemia

The correct answer is Initiate oxygen therapy to improve oxygenation.

When analyzing this clinical scenario, the priority is determined by applying the Airway, Breathing, Circulation (ABC) framework, a fundamental principle for NCLEX-RN prioritization questions. The child's oxygen saturation is 88% on room air, which indicates significant hypoxemia. In the hierarchy of physiological needs, oxygenation is the most immediate and critical concern because hypoxemia can rapidly lead to cellular dysfunction, tissue damage, and life-threatening deterioration.

The pathophysiology of pneumonia involves inflammation and fluid accumulation within the alveoli, which impairs gas exchange. This ventilation-perfusion mismatch prevents oxygen from effectively diffusing into the pulmonary capillaries, leading to a drop in arterial oxygen saturation. A respiratory rate of 40 breaths/minute is the child's compensatory mechanism for this hypoxemia, an attempt to increase minute ventilation. However, this increased work of breathing is not sustainable and signals impending respiratory distress. The provided evidence underscores the critical nature of respiratory support in severe pediatric pneumonia, as the study by Ijaz et al. (2026) specifically investigated the implementation and safety of bubble continuous positive airway pressure (bCPAP), a low-cost respiratory support device, for children with severe pneumonia [1]. The very existence and study of such devices highlight that correcting hypoxemia is the cornerstone of initial stabilization and management.

The other options are not the immediate priority. Administering acetaminophen addresses the fever of 102.8°F (39.3°C), which increases metabolic rate and oxygen consumption. While reducing fever is beneficial, it is a secondary intervention that does not directly correct the life-threatening hypoxemia. Providing emotional support to anxious parents is an essential component of family-centered care but is a psychosocial need that is deferred until physiological stability is achieved. Encouraging increased fluid intake helps prevent dehydration and can mobilize secretions, but this intervention is contraindicated in a child with significant tachypnea and hypoxemia due to the risk of aspiration, and it does not address the immediate oxygen deficit. The airway and breathing take absolute precedence. The study's focus on implementation fidelity, including patient monitoring, reinforces that the first step in a safe care pathway is ensuring adequate respiratory support [1].References (research sources)

## 임상 시나리오

Pediatric Pneumonia: Oxygen Therapy PriorityImmediate Intervention for Hypoxemic Respiratory Distress
Apply the ABC framework strictly: an SpO2 of 88% on room air indicates critical hypoxemia requiring immediate oxygen therapy to prevent cellular dysfunction and deterioration.

A respiratory rate of 40 breaths/min in a 4-year-old with pneumonia is a compensatory tachypnea for ventilation-perfusion mismatch, signaling unsustainable increased work of breathing.

CautionDo not delay respiratory support for secondary interventions like antipyretics or hydration. Hypoxemia is the most immediate life threat; administer oxygen first, then reassess.

## 핵심 개념

- **Hypoxemia** — An abnormally low concentration of oxygen in the arterial blood, indicated by an SpO2 below the normal range, which can lead to tissue hypoxia.
- **ABC Framework** — A prioritization model in nursing (Airway, Breathing, Circulation) used to identify and manage the most life-threatening client needs first.
- **Ventilation-Perfusion Mismatch** — An imbalance in the lung where air sacs receive oxygen but not enough blood flow, or vice versa, commonly caused by fluid-filled alveoli in pneumonia.
- **Tachypnea** — An abnormally rapid respiratory rate, often a compensatory mechanism to increase minute ventilation in response to hypoxemia or fever.
- **Minute Ventilation** — The total volume of gas entering or leaving the lungs per minute, calculated by multiplying tidal volume by respiratory rate.
