QUESTIONS AND SOLUTIONS GRADED A+
●● 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. Which is the most appropriate initial
intervention for this child?.
Answer: Humidified oxygen as tolerated
●● You are part of a team attempting to resuscitate a child with
ventricular fibrillation cardiac arrest. You delivered 2 unsynchronized
shocks. A team member established IO access, so you give a dose of
epinephrine, 0.01 mg/kg IO. At the next rhythm check, persistent
ventricular fibrillation is present. You administer a 4 J/kg shock and
resume CPR. Which drug and dose should be administered next?.
Answer: Amiodarone 5 mg/kg IO
●● Which statement is correct about the effects of epinephrine during
