A 9-year-old boy is agitated and leaning forward on the bed in obvious respiratory distress. The
patient is speaking in short phrases and tells you that he has asthma but does not carry an inhaler.
He has nasal flaring, severe suprasternal and intercostal retractions, and decreased air movement
with prolonged expiratory time and wheezing. You administer 100% oxygen by a nonrebreathing
mask. His SpO2 is 92%. Which medication do you prepare to give to this patient?
A. Adenosine
B. Procainamide
C. Amiodarone
D. Albuterol (Correct)
Which oxygen delivery system most reliably delivers a high (90% or greater) concentration of
inspired oxygen to a 7-year-old child?
A. Face tent
B. Simple oxygen mask
C. Nonrebreathing face mask (Correct)
D. Nasal cannula
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?
A. Magnesium sulfate 25 to 50 mg/kg IO
B. Epinephrine 0.1 mg/kg IO
C. Atropine 0.02 mg/kg IO
D. Amiodarone 5 mg/kg IO (Correct)
Which statement is correct about the effects of epinephrine during attempted resuscitation?
A. Epinephrine decreases myocardial oxygen consumption
B. Epinephrine is contraindicated in ventricular fibrillation
C. Epinephrine stimulates spontaneous contractions when asystole is present (Correct)
D. Epinephrine decreases peripheral vascular resistance and reduces myocardial afterload
