## 문제

A 2-year-old toddler is admitted to the pediatric unit with a diagnosis of pertussis (whooping cough). The toddler has been experiencing severe paroxysmal coughing episodes followed by inspiratory whooping sounds. Which nursing intervention should be the priority for this toddler?

## 보기

1. Administer prescribed antibiotics on schedule to reduce bacterial load
2. Position the infant prone or side-lying to facilitate drainage of secretions **✔ 정답**
3. Provide frequent small feedings to maintain adequate nutrition
4. Monitor oxygen saturation continuously with pulse oximetry

**정답: 2**

## 해설

Positioning prone or side-lying is the priority to prevent aspiration and facilitate secretion drainage during coughing episodes. Other interventions like antibiotics, nutrition, and monitoring are important but secondary to airway safety.

## 심화 해설

Understanding the Priority in Pertussis Care

The correct answer is Position the infant prone or side-lying to facilitate drainage of secretions. For a 2-year-old toddler with pertussis, the immediate threat to life during a paroxysmal coughing episode is a compromised airway. The severe, rapid coughing fits can produce thick, tenacious secretions that the child cannot clear effectively, leading to airway obstruction, apnea, and hypoxia. The inspiratory "whoop" sound itself is a sign of a narrowed, partially obstructed airway as the child forcefully inhales against a closed glottis. Therefore, the priority nursing intervention is rooted in the Airway, Breathing, Circulation (ABC) framework. Positioning the child to promote gravity-assisted drainage of these secretions is a direct, non-invasive method to maintain airway patency. This action helps prevent pooling of mucus in the oropharynx and trachea, which can trigger further coughing spasms or complete obstruction.

Analyzing the Incorrect Options

While all other options are important components of holistic care for a child with pertussis, they do not address the most immediate life-threatening risk.

- Option 1: Administering prescribed antibiotics is crucial for eliminating Bordetella pertussis and reducing infectivity. However, its effect is not immediate. Antibiotics primarily limit the spread of infection and can shorten the disease course if given early, but they do not reverse the existing damage to the respiratory cilia or immediately halt the paroxysmal stage. The airway clearance issue remains a more urgent, moment-to-moment concern.

- Option 3: Providing frequent small feedings is an important strategy to maintain nutrition and prevent dehydration, as large meals can trigger coughing fits and lead to vomiting. This addresses a long-term physiological need but is not the priority during an acute crisis of airway compromise.

- Option 4: Monitoring oxygen saturation continuously with pulse oximetry is a valuable assessment tool to detect hypoxemia early. However, it is a passive monitoring intervention, not an action that actively prevents or resolves the airway obstruction. A nurse would not simply monitor a dropping oxygen saturation without first implementing an intervention to correct the underlying problem, which is the secretion-filled airway.

Clinical Reasoning and Application

The nursing process dictates that assessment and intervention for the most critical physiological need come first. In the context of pertussis, the paroxysmal stage is characterized by a cycle of uncontrollable coughing, a struggle to inhale, and potential post-tussive emesis or apnea. The primary nursing action is to be prepared for these episodes and intervene to protect the airway. Placing the child in a prone or side-lying position with the head slightly lowered is an evidence-based practice to use gravity to drain secretions away from the airway. This is a direct application of airway management principles, which is the foundation of pediatric emergency care. The nurse must also be prepared with suction equipment and emergency respiratory support, but the first physical action is optimal positioning to facilitate natural drainage and maintain a clear airway.

Clinical Practice Guide: Airway Management in Pertussis

For a toddler with pertussis, the priority during a paroxysmal coughing episode is to maintain a patent airway. Position the child prone or side-lying to use gravity to drain thick secretions from the oropharynx and trachea, preventing obstruction and reducing coughing spasm triggers. This aligns with the ABC framework, where airway clearance takes precedence over medication administration, feeding, or monitoring. Have suction equipment ready at the bedside, and avoid supine positioning which can worsen secretion pooling. Educate caregivers on recognizing signs of airway compromise, such as apnea or cyanosis, and the importance of this positioning technique at home.

## 핵심 개념

- **Pertussis (Whooping Cough)** — A highly contagious respiratory infection caused by Bordetella pertussis, characterized by severe paroxysmal coughing fits followed by an inspiratory whooping sound, posing a high risk of airway obstruction in toddlers.
- **Paroxysmal Coughing** — Sudden, uncontrollable episodes of rapid coughing that can lead to hypoxia, apnea, and difficulty clearing thick respiratory secretions, requiring immediate airway management.
- **ABC Priority Framework** — A systematic approach in emergency and critical care that prioritizes Airway, Breathing, and Circulation, guiding nurses to first address immediate threats to airway patency.
