Croup is characterized by the classic barking cough, inspiratory stridor, and low-grade fever in young children.

Question 2

A 4-year-old presents with sudden onset of choking, unilateral wheezing, and decreased breath sounds on the right. What is the priority intervention?

Accepted Answer

Prepare for bronchoscopy

Answer

Sudden unilateral wheezing with decreased breath sounds strongly suggests foreign body aspiration, requiring bronchoscopy for removal.

Question 3

Which oxygen delivery method provides the highest inspired oxygen concentration for a spontaneously breathing, critically ill pediatric patient?

Accepted Answer

Non-rebreather mask

Answer

A non-rebreather mask with a reservoir bag and one-way valves can deliver up to 90–95% oxygen concentration.

Accepted Answer

Ipratropium bromide plus systemic corticosteroids

Answer

Ipratropium bromide combined with systemic corticosteroids is standard adjunct therapy for moderate asthma exacerbations not resolved by albuterol alone.
