A child is seen in the emergency department. The nurse hears a high-pitched squeal every time the child inhales. The parent states that the child’s fever is very high and, in addition, the child is gasping for breath and sitting in the tripod position. Which of the following actions would be appropriate for the nurse to perform at this time?

Croupis a viral infection that causes inflammation and swelling of the upper airway structures, especially the larynx, trachea, and sometimes bronchi, resulting in the characteristic barking cough and respiratory symptoms.

Rationale for correct answer:

3. “The cough is caused by inflammation and swelling in the trachea and the bronchi, leading to airway narrowing.”The hallmark barking coughof croup occurs because inflammation narrows the airway, causing turbulent airflow and irritation that triggers the cough reflex. This swelling reduces the airway diameter, producing the distinctive "seal-like" sound and respiratory distress.

Rationale for incorrect answers:

1. “The cough indicates a severe allergic reaction that is causing the airways to constrict rapidly.”While allergic reactions can cause airway constriction, the croup cough is not due to an allergic process but an inflammatory viral infection.

2. “The cough is a reflex to clear mucus and other secretions from the lungs in children with a respiratory illness.”The cough in croup is primarily due to upper airway narrowing, not just mucus clearance from the lungs.

4. “The child is making this sound due to anxiety and distress about their condition.”Anxiety may worsen respiratory symptoms but is not the cause of the characteristic barking cough.

Take home points

• The barking cough in croup is caused by inflammation and swelling of the upper airway leading to narrowing.
• Understanding this helps caregivers appreciate the importance of treatment to reduce airway edema.
• Reassure parents that the cough is a sign of the body’s response to airway irritation, not anxiety or allergy.

A nighttime cough in a young child without fever often indicates mild upper respiratory irritation or postnasal drip. Non-pharmacologic comfort measures can help reduce coughing and promote better sleep without unnecessary medication.

Rationale for correct answer:

3. Raising the head of the baby’s crib can help reduce coughingby promoting drainage of nasal secretions and reducing postnasal drip that irritates the throat. This simple intervention is safe, non-invasive, and can improve the child’s comfort and sleep quality.

Rationale for incorrect answers:

1. Steam vaporizersplaced too close can cause burns or be a safety hazard. Cold mist humidifiers used properly can help, but the placement should be safe and not directly next to the child’s face or crib.

2. Nonprescription cough and cold medicinesare not recommended for children under 2 years due to lack of efficacy and potential serious side effects. The FDA advises against their use in infants and toddlers.

4. Antibioticsare not appropriate without signs of bacterial infection such as fever or purulent symptoms. Most coughs in toddlers are viral and self-limiting.

Take home points

• For mild nighttime cough without fever in toddlers, non-pharmacologic measures like elevating the head of the crib can improve comfort.
• Avoid over-the-counter cough and cold medicines in children under 2 due to safety concerns.
• Antibiotics should not be prescribed unless bacterial infection is clearly suspected.
