Explanation lettering: C = shown as A · D = shown as B · A = shown as C · B = shown as D
C is correct. Stridor at rest with marked retractions is moderate-to-severe croup: dexamethasone treats the inflammation and nebulized epinephrine provides rapid temporary relief, requiring observation for recurrence. D treats neither upper-airway edema nor typical viral croup. E relies on ineffective mist and misreads oxygen saturation. A may agitate and worsen obstruction. B is unsafe and delays treatment. Failure to improve or atypical features require airway and alternative-diagnosis reassessment.
