- correct answer -Ventricular fibrillation
, - correct answer -Sinus tachycardia
Administer a bolus of isotonic crystalloid 20 ml/kg over 5-20 minutes, and also give D25W 2-4
ml/kg IV - correct answer -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?
Albuterol (duh) - correct answer -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?
Rapid bolus of 20ml/kg of isotonic crystalloid - correct answer -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?
Epinephrine - correct answer -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?
