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 mmHg, and glucose is 30 mg/dL (1.65 mmol/L) - correct
, answer. Administer a bolus of isotonic crystalloid 20 ml/kg over 5-20 minutes, and
also give D25W 2-4 ml/kg IV
A 9yo 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 med do
you prepare to give to this patient? - correct answer. Albuterol (duh)
Paramedics are called to the home of a 1yo child. Their initial assessment reveals a
child who responds only to painful stimuli and has irregular breathing, faint central
pulses, bruises over the abdomen, abdominal distention, and cyanosis. Bag-mask
ventilation with 100% oxygen is initiated. The child's heart rate is 36/min. Peripheral
pulses cannot be palpated, and central pulses are barely palpable. The cardiac monitor
shows sinus bradycardia. Two-rescuer CPR is started. Upon arrival to the em - correct
answer. Rapid bolus of 20ml/kg of isotonic crystalloid
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
Which statement is correct about the use of calcium chloride in pediatric patients? -
correct answer. Routine administration is not indicated during cardiac arrest
Which statement is correct about endotracheal drug administration during resuscitative
efforts for pediatric patients? - correct answer. It is the least desirable route of
administration
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 - correct 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? - correct answer.
Amiodarone 5 mg/kg IO
