## 문제

A 9-month-old infant is admitted to the pediatric unit with a diagnosis of respiratory syncytial virus (RSV) bronchiolitis. The infant is experiencing moderate respiratory distress with nasal flaring, intercostal retractions, and oxygen saturation of 88% on room air. Which nursing intervention should be the priority?

## 보기

1. Administer bronchodilators as prescribed to improve airway patency

3. Encourage increased fluid intake to prevent dehydration
4. Perform chest physiotherapy to mobilize secretions

**정답: 2**

## 해설

Positioning and supplemental oxygen are priorities to address hypoxia and improve breathing mechanics in infants with RSV bronchiolitis. Other options like bronchodilators or fluids are supportive but not immediate for respiratory distress.

## 심화 해설

Correct Answer

2. Position the infant in a semi-Fowler's position and provide supplemental oxygen

Rationale

The priority nursing intervention for an infant with moderate respiratory syncytial virus (RSV) bronchiolitis who presents with significant respiratory distress (nasal flaring, intercostal retractions) and hypoxemia (oxygen saturation of 88% on room air) is to address the immediate threat to oxygenation and ventilation. Positioning the infant in a semi-Fowler's position optimizes lung expansion by reducing pressure from the abdominal organs on the diaphragm, while administering supplemental oxygen directly corrects the life-threatening hypoxemia. This approach aligns with the foundational Airway, Breathing, Circulation (ABC) framework used in nursing prioritization.

The evidence-based guidelines for bronchiolitis management consistently emphasize that the mainstay of treatment is supportive care, which fundamentally includes respiratory support and maintenance of adequate oxygenation and hydration [2]. A clinical audit on optimizing pediatric bronchiolitis management reinforced that adherence to these guidelines focuses on providing supportive interventions rather than unproven pharmacological or physical therapies [2]. The immediate clinical presentation of an oxygen saturation of 88% signals a critical impairment in gas exchange at the alveolar-capillary level, secondary to inflammation and mucous plugging of the bronchioles. The nurse's priority is to correct this hypoxemia to prevent further decompensation and potential respiratory failure.

Why the Other Options Are Not the Priority

Option 1: Administer bronchodilators as prescribed to improve airway patency.

While bronchodilators may be prescribed, current international guidelines do not recommend their routine use in the management of bronchiolitis. The pathophysiology of RSV bronchiolitis involves necrotic debris and edema causing airway obstruction, not primarily bronchospasm as seen in asthma. Clinical audits have shown that reducing the use of avoidable interventions like bronchodilators is a key target for improving evidence-based practice and reducing potential patient harm [2]. Therefore, this pharmacological intervention is not the first-line priority over immediate oxygenation and positioning.

Option 3: Encourage increased fluid intake to prevent dehydration.

Maintaining hydration is a critical component of supportive care for bronchiolitis [2]. However, in an infant with moderate to severe respiratory distress, the work of breathing is significantly elevated. A tachypneic infant with a respiratory rate that may be dangerously high is at extreme risk for aspiration if oral intake is encouraged. The immediate priority is to stabilize the respiratory status; once the infant’s breathing effort is reduced and oxygenation is stabilized, hydration can be carefully managed, often through intravenous or nasogastric routes if the respiratory rate remains too high for safe oral feeding.

Option 4: Perform chest physiotherapy to mobilize secretions.

Chest physiotherapy is not recommended in the routine management of bronchiolitis. The obstruction in the small airways is due to inflammation, edema, and debris within the lumen, not loose secretions in large airways that can be mobilized by percussion or vibration. Evidence-based audits aim to eliminate such avoidable and non-beneficial interventions from clinical practice [2]. Performing chest physiotherapy would not address the critical hypoxemia and could potentially increase the infant’s distress and oxygen consumption, making it a non-priority and potentially harmful action in this acute scenario.

Clinical Application of Advanced Nursing Practice

The decision-making process for a nurse at the bedside mirrors the advanced triage and stabilization principles used in specialized pediatric transport teams. When managing an infant with moderate-to-severe bronchiolitis, the initial assessment must rapidly identify and intervene on the most life-threatening elements. A study on inter-hospital transfer of these patients highlights that the critical interventions during the initial stabilization phase are focused on securing the airway and providing adequate respiratory support before any transport or further treatment occurs . The nurse’s role is to execute these same immediate priorities: optimize the infant’s position to reduce work of breathing and apply supplemental oxygen to reverse hypoxemia, thereby stabilizing the patient for subsequent diagnostic or therapeutic procedures.References (research sources)

## 임상 시나리오

Clinical Scenario

A 9-month-old infant with RSV bronchiolitis presents with moderate respiratory distress: nasal flaring, intercostal retractions, and an oxygen saturation of 88% on room air. The immediate priority is to correct the life-threatening hypoxemia and support ventilation.

Priority Nursing Actions

- **Positioning:** Place the infant in a semi-Fowler's position (head of bed elevated 30-45 degrees) to reduce abdominal pressure on the diaphragm and optimize lung expansion.

- **Oxygen Therapy:** Administer supplemental oxygen via a nasal cannula or face mask to maintain oxygen saturation above 90-92%, titrating the flow rate based on continuous pulse oximetry.

- **Continuous Monitoring:** Closely monitor respiratory rate, heart rate, oxygen saturation, and work of breathing (retractions, nasal flaring, grunting) to detect deterioration early.

Supportive Care Guidelines

- **Suctioning:** Perform gentle nasal suctioning with a bulb syringe or catheter before feedings and as needed to clear secretions, as infants are obligate nose breathers.

- **Hydration:** Offer small, frequent feedings. Monitor for signs of dehydration (decreased wet diapers, dry mucous membranes). IV fluids may be necessary if oral intake is poor.

- **Minimize Stimulation:** Cluster care activities to reduce oxygen consumption and allow for rest periods, as excessive handling can worsen respiratory distress.

Interventions to Avoid

- **Bronchodilators:** Not routinely recommended for RSV bronchiolitis as evidence shows limited benefit unless there is a clear history of asthma or atopy.

- **Chest Physiotherapy:** Ineffective in mobilizing secretions in bronchiolitis and may increase infant distress and oxygen demand.

- **Routine Corticosteroids:** Not indicated for first-time wheezing associated with RSV bronchiolitis per current clinical practice guidelines.

## 핵심 개념

- **Respiratory Syncytial Virus (RSV) Bronchiolitis** — A common lower respiratory tract infection in infants causing inflammation and mucus plugging of the bronchioles, leading to respiratory distress and impaired gas exchange.
- **Semi-Fowler's Position** — A position where the head of the bed is elevated to approximately 30-45 degrees, which optimizes lung expansion by reducing abdominal pressure on the diaphragm.
- **ABC Prioritization** — A nursing framework that prioritizes interventions based on Airway, Breathing, and Circulation, addressing the most life-threatening issues first.
- **Hypoxemia** — An abnormally low concentration of oxygen in the arterial blood, indicated by an oxygen saturation of 88% on room air, requiring immediate correction.
- **Intercostal Retractions** — Visible sinking of the tissues between the ribs during inspiration, a sign of increased work of breathing and moderate to severe respiratory distress.
