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
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?
A. Atropine
B. Dopamine
C. Adenosine
D. Epinephrine (Correct)
Which statement is correct about endotracheal drug
administration during resuscitative efforts for
pediatric patients?
A. The intravenous drug dose should be used
B. It is the preferred route of drug administration
C. It is the least desirable route of administration
(Correct)
D. The drug dose used is lower than the intravenous
dose
Which statement is correct about the use of calcium
chloride in pediatric patients?
A. It has the same bioavailability of elemental
calcium as calcium gluconate
B. The recommended dose is 1 to 2 mg/kg
C. Routine administration is not indicated
during cardiac arrest (Correct)
D. It is indicated for hypercalcemia, hypokalemia,
and hypomagnesemia
A previously healthy infant with a history of
vomiting and diarrhea is brought to the emergency
department by her parents. During your assessment,
you find that the infant responds only to painful
stimulation. The infant’s respiratory rate is 40
breaths per minute, and central pulses are rapid and
weak. The infant has good bilateral breath sounds,
cool extremities, and a capillary refill time of more
than 5 seconds. The infant’s blood pressure is 85/65
mm Hg, and glucose is 30 mg/dL (1.65 mmol/L).
You administer 100% oxygen via face mask and
start an IV. Which treatment is the most appropriate
for this infant?
A. Administer a bolus of isotonic crystalloid 20
mL/kg over 5 to 20 minutes, and also give D25W
2 to 4 mL/kg IV (Correct)
B. Administer lactated Ringer’s solution 20 mL/kg
over 60 minutes
C. Administer D50W 0.45% sodium chloride 20
mL/kg bolus over 15 minutes
D. Administer D10W 20 mL/kg bolus over 5
minutes
Initial impression of a 2-year-old 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
