Question: 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 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 mmHg and glucose is 30 mg/dL. You administer 100%
oxygen via face mask and start an IV. Which treatment is the
most appropriate for this infant?
a) Administer D50W 0.45% NaCl 20 mL/kg bolus over 15
minutes
b) Administer LR solution 20 mL/kg over 60 minutes
c) Administer a bolus of isotonic crystalloid 20 mL/kg over 5 to
20 minutes and also give D25W 2 to 4 mL/kg IV
d) Administer D10W 20 mL/kg over 5 minutes
Answer: c) Administer a bolus of isotonic crystalloid 20 mL/kg over 5 to 20 minutes and also
give
D25W 2 to 4 mL/kg
Question: 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) The drug dose used is lower than the intravenous dose
d) It is the least desirable route of administration
Answer: d) It is the least desirable route of administration
Question: Which statement is correct about the effects of epinephrine
during attempted resuscitation?
a) Epi decreases peripheral vascular resistance and reduces
myocardial afterload
b) Epi stimulates spontaneous contractions when asystole is
present
c) Epi decreases myocardial oxygen consumption
d) Epi is contraindicated in VFib
Answer: Epinephrine stimulates spontaneous contractions when asystole is present
, Question: Which oxygen delivery system most reliably delivers a high
(90% or greater) concentration of inspired oxygen to a 7yo
child?
a) nasal cannula
b) simple oxygen mask
c) nonrebreather face mask
d) face tent
Answer: c) nonrebreathing face mask
Question: 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 POx is 92%. Which
medication do you prepare to give to this patient?
a) Albuterol
b) Adenosine
c) Amiodarone
d) Procainamide
Answer: a) Albuterol
Question: You are part of team attempting to resuscitate a child with
ventricular fibrillation cardiac arrest. You deliver 2
unsynchronized shocks. A team member established IO
access, so you give a dose of epi, 0.01 mg/kg IO. At the next
rhythm check, persistent ventricular fibrillation is present. You
administer a 4-J/kg shock ad 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
Answer: d) Amiodarone 5 mg/kg IO
