## 문제

A 6-year-old child diagnosed with influenza is being cared for at home. The child has a fever of 101.5°F (38.6°C), cough, and mild dehydration signs. The parents ask the nurse about appropriate interventions to manage their child's symptoms. Which nursing intervention should the nurse prioritize?

## 보기

1. Administer aspirin every 4 hours for fever and pain relief
2. Encourage the child to return to school once fever subsides for 12 hours
3. Ensure adequate fluid intake and rest **✔ 정답**
4. Apply cool compresses to the forehead continuously until fever breaks

**정답: 3**

## 해설

The priority intervention is ensuring adequate fluid intake and rest while monitoring for complications, as this supports hydration, energy conservation, and safety. Other options are unsafe (aspirin risk) or premature (school return).

## 심화 해설

Clinical Context and Priority Setting

In the home management of a pediatric patient with influenza, the nurse must prioritize interventions that address the most immediate physiological risks while avoiding harmful practices. Influenza in children commonly presents with fever, cough, and the potential for dehydration, which can lead to more serious complications if not managed appropriately. The clinical practice guideline on outpatient management of fever emphasizes that the primary goals are comfort and prevention of dehydration, rather than aggressive fever reduction itself . A case report on influenza-associated necrotizing pneumonia illustrates how a seemingly typical viral illness can rapidly progress to a life-threatening condition, underscoring the importance of vigilant supportive care and monitoring even in the home setting .

Analysis of Correct Answer (Option 3)

Ensuring adequate fluid intake and rest is the foundational, evidence-based priority. Fever increases insensible water loss through the skin and respiratory tract, and coupled with reduced oral intake, a child is at high risk for developing significant dehydration. The guideline identifies the maintenance of hydration as a key supportive measure in febrile children . Rest reduces metabolic demand and supports the immune system's ability to combat the viral infection. This intervention directly addresses the presenting sign of mild dehydration and prevents its progression, which is a higher physiological priority than treating the fever itself.

Analysis of Incorrect Options

**Option 1:** Administering aspirin to a child with a viral illness like influenza is strictly contraindicated due to the established link with Reye's syndrome, a rare but severe condition causing acute encephalopathy and liver failure. The fever management guideline explicitly advises against the use of acetylsalicylic acid (aspirin) as an antipyretic in children . This makes the option not just a lower priority, but a dangerous intervention.

**Option 2:** Encouraging a return to school once the fever subsides for 12 hours is incorrect from an infection control perspective. Children with influenza are typically considered contagious for a longer period, and returning to a communal setting too soon facilitates the spread of the virus. Epidemiological data on pediatric infectious diseases highlight the importance of understanding transmission patterns to implement effective prevention strategies, which includes appropriate isolation during the infectious period . The priority is community health safety, not just the individual's symptom resolution.

**Option 4:** Applying cool compresses continuously is an external cooling method that can cause shivering and peripheral vasoconstriction. Shivering actually generates heat, raising the body's core temperature and working against the goal of fever reduction. This method also causes significant discomfort. The guideline notes that external cooling is not recommended as a routine antipyretic measure because it can induce thermoregulatory stress without treating the underlying febrile process .

Pathophysiology and Clinical Reasoning

Fever is a regulated elevation of the hypothalamic set-point, primarily mediated by pyrogens released during an immune response to the influenza virus. The body actively works to maintain this new, higher temperature. Interventions like external cooling fight the body's own physiological mechanism, leading to discomfort and compensatory heat production. In contrast, ensuring fluid intake supports the circulatory volume, which is compromised by increased losses. The case of the child who developed necrotizing pneumonia demonstrates that even in previously healthy children, influenza can cause severe epithelial damage and a hyperinflammatory response, making supportive care like hydration and rest critical for preventing secondary deterioration . While that case occurred in a hospital setting, the underlying principle of meticulous supportive care begins at home. The use of respiratory pathogen panels in febrile pediatric patients, as studied in oncology populations, confirms that identifying a specific virus like influenza helps guide management, but the cornerstone of care remains supportive .

## 임상 시나리오

Home Management of Pediatric InfluenzaPrioritizing Supportive Care for Fever and Dehydration
The primary goals in managing a child with influenza are comfort and prevention of dehydration, not aggressive fever reduction. Fever increases insensible water loss, making hydration a critical intervention.

Ensure the child receives adequate fluid intake (e.g., water, oral rehydration solutions) and gets plenty of rest. Monitor for signs of worsening dehydration such as decreased urine output, dry mucous membranes, or lethargy.

CautionNever administer aspirin to a child with a viral illness due to the risk of Reye's syndrome. The child should remain isolated from others until they are fever-free for at least 24 hours without the use of antipyretics.

## 핵심 개념

- **Reye's syndrome** — A rare but serious condition causing liver and brain swelling, linked to aspirin use in children with viral infections.
- **Insensible water loss** — Fluid loss not perceived by the individual, occurring through the skin and respiratory tract, increased by fever.
- **Antipyretics** — Medications such as acetaminophen or ibuprofen used to reduce fever.
- **Tepid sponging** — The application of lukewarm water to the skin to lower body temperature, no longer routinely recommended due to discomfort and shivering.
