You are called to help treat an infant with severe symptomatic bradycardia (heart rate 66/min) associated with respiratory distress. The bradycardia persists despite establishment of an effective airway, oxygenation, and ventilation. There is no heart block present. Which is the first drug you should administer? Correct Answer-Epinephrine Initial impression of a 2yo girl shows her to be alert with mild breathing difficulty during inspiration and pale skin color. On primary assessment, she makes high-pitched inspiratory sounds (mild stridor) when agitated; otherwise, her breathing is quiet. Her spO2 is 92% on room air, and she has mild inspiratory intercostal retractions. Lung auscultation reveals transmitted upper airway sounds with adequate distal breath sounds bilaterally.
