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). You
administer 100% oxygen via face mask and start an IV. Which treatment is most appropriate for this
infant? - (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? - (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 emergency
department, the child is intubated and ventilated with 100% oxygen, and IV access is established. The
heart rate is now 150/min with weak central pulses but no distal pulses. Systolic blood pressure is 74
mmHg. Which intervention should be provided next? - (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? - (ANSWER)Epinephrine
Which statement is correct about the use of calcium chloride in pediatric patients? - (ANSWER)Routine
administration is not indicated during cardiac arrest
