Which instruction should a nurse give the parents of a 2-year-old child who wakes in the night with a barking cough?
Provide humidified air for the child to breath.
Call for an ambulance immediately.
Place the child in a warm, dry room.
Begin rescue breathing at once.
The Correct Answer is A
Acute spasmodic laryngitis (“midnight croup”) is a sudden-onset, viral upper airway infection that typically affects children aged 6 months to 3 years. It presents with barking, seal-like cough, inspiratory stridor, mild to moderate respiratory distress. It often occurs at night and worsens suddenly. Most episodes are self-limiting and can be managed safely at home with supportive care unless distress becomes severe.
Rationale for correct answer:
1. Cool, humidified air from a humidifier, cool mist vaporizer, or stepping outside into cool night air, reduces laryngeal swelling, eases breathing, and relieves the barking cough. This is the first-line, noninvasive intervention for nighttime croup episodes at home. Parents should remain calm, keep the child upright, and observe for worsening symptoms.
Rationale for incorrect answers:
2. Most mild croup episodes are not emergencies. Emergency services are needed only if the child shows severe distress such as stridor at rest, retractions, cyanosis, or lethargy.
3. Warm, dry air can increase airway inflammation and worsen symptoms. Cool, humid air is more effective for reducing airway swelling.
4. Rescue breathing is not indicated for mild croup. Only if the child stops breathing or becomes unresponsive should emergency measures like CPR be initiated.
Take home points
- Midnight croup is usually mild and self-limiting.
- Cool, humidified air is the most effective first-line intervention at home.
- Keep the child calm and upright; agitation can worsen airway obstruction.
- Seek emergency care if stridor occurs at rest, retractions worsen, or the child becomes cyanotic, lethargic, or unable to swallow fluids.

Correct Answer is B
Explanation
Acute epiglottitisis a medical emergencymost often caused by Haemophilus influenzae type B (Hib). It results in rapid swelling of the epiglottis, leading to airway obstruction. Typical presentation includes sudden onset of high fever, drooling, severe sore throat, dysphagia, muffled voice, stridor, tripod positioning, absence of cough, anxiety and restlessness due to respiratory distress.
Rationale for correct answer:
2. The child is in the tripod position and has diminished breath sounds and a muffled cough: This finding indicates severe airway obstruction and impending respiratory failure. Tripod position and muffled cough are hallmark signs of epiglottitis. Diminished breath soundssignal that air movement is critically reduced, a life-threatening emergency requiring immediate airway management and preparation for intubation. The child should not be examined or agitated; emergency airway equipment should be ready, and the provider notified immediately.
Rationale for incorrect answers:
1. The child is lying down and has moderate retractions, low-grade fever, and nasal congestion: This is consistent with nasopharyngitis (common cold) or mild upper respiratory infection, not an emergency. The airway is patent.
3. The child is sitting up and has coarse breath sounds, coughing, and fussiness: These findings are more consistent with bronchiolitis or viral croup, which cause airway inflammation but typically have a characteristic cough and coarse sounds, not a muffled voice or tripod positioning.
4. The child is restless and crying, has bilateral wheezes, and is feeding poorly: This presentation suggests asthma or reactive airway disease, not epiglottitis. While concerning, wheezing indicates air is still moving, unlike the silent chest seen in impending obstruction from epiglottitis.
Take home points
- Tripod position, muffled voice, and diminished breath sounds signify airway emergency.
- Do not attempt throat inspection or use a tongue blade since this can trigger complete obstruction.
- Keep emergency intubation and tracheostomy equipment ready at the bedside.
- Calm the child, avoid unnecessary interventions, and notify the provider immediately.
Correct Answer is D
Explanation
Croup (laryngotracheobronchitis)severity varies based on age, airway size, and immune response. Children under 3 years have smaller, more pliable airways, which are easily obstructed by inflammation and edema. Their immune systems are still developing, which may contribute to more pronounced symptoms and higher risk of respiratory distress compared with older children.
Rationale for correct answer:
4. “Children younger than 3 years usually exhibit worse symptoms because their immune systems are not as developed.”This response is factually correct and helps the parent understand why severity varies among children. It reassures the parent that the child’s hospitalization is based on age-related risk and airway safety, not neglect or unusual illness. Provides education and context without blaming the parent.
Rationale for incorrect answers:
1. “Some children just react differently to viruses. It is best to treat each child as an individual.”While partially true, it is too vague and does not explain why younger children are at higher risk for severe croup.
2. “Younger children have wider airways that make it easier for bacteria to enter and colonize.”Younger children have narrower, not wider, airways, which contributes to obstruction, not bacterial colonization. Croup is viral, not bacterial in most cases.
3. “Younger children have short and wide eustachian tubes, making them more susceptible to respiratory infections.”This is true for otitis media, but not relevant to croup, which affects the larynx and trachea, not the middle ear.
Take home points
- Age <3 years is a major risk factor for severe croup due to small, easily obstructed airways and immature immune systems.
- Parents should understand that hospitalization is for airway safety and monitoring, not necessarily because the virus is more severe.
- Education and reassurance help reduce parental anxiety and improve adherence to care recommendations.
