PALS Precourse Test Questions And Answers 2022 PALS Precourse Test Questions And Answers 2022
Parents of a 1-year-old female phoned EMS when they picked
... [Show More] up their daughter from
the babysitter. Paramedics perform an initial impression revealing an obtunded infant
with irregular breathing, bruises over the abdomen, abdominal distension, and cyanosis.
Assisted bag-mask ventilation with 100% oxygen is initiated. On primary assessment
heart rate is 36/min, peripheral pulses cannot be palpated, and central pulses are barely
palpable. Cardiac monitor shows sinus bradycardia. Chest compressions are started at
15:2. In the ED the infant is intubated and ventilated, and IV access is established. The
heart rate is now up to 150/min, but there are weak central pulses and no distal pulses.
Systolic BP is 74. Of the following, which would be most useful in management of this
infant?
A. Synchronized cardioversion
B. Epinephrine 0.01 mg/kg (0.1 mL/kg of 1:10,000 dilution) IV
C. Rapid bolus of 20 mL/kg of isotonic crystalloid
D. Atropine 0.02 mg/kg IV - Answer - C
You enter a room to perform an initial impression of a previously stable 10-year-old male
and find him unresponsive and apneic. A code is called and bag-mask ventilation is
performed with 100% oxygen. The cardiac monitor shows a wide-complex tachycardia.
The boy has no detectable pulses so compressions and ventilations are provided. As
soon as the defibrillator arrives you deliver an unsynchronized shock with 2 J/kg. The
rhythm check after 2 minutes of CPR reveals VF. You then deliver a shock of 4 J/kg and
resume immediate CPR beginning with compressions. A team member has established
IO access, so you give a dose of epi, 0.01 mg/kg (0.1 mL/kg of 1:10,000 dilution) IO
after second shock. At the next rhythm check, persistent VF is present. You administer
another 4 J/kg shock and resume CPR. Based on the PALS Pulseless Arrest Algorithm,
what is the next drug and dose to administer when CPR is restarted?
A. Magnesium sulfate 25-50 mg/kg IO
B. Atropine 0.02 mg/kg IO
C. Epinephrine 0.1 mg/kg of 1:10,000 dilution IO
D. Amiodarone 5 mg/kg IO - Answer - D
Which of the following statements about calcium is true?
A. Calcium chloride 10% has the same bioavailability of elemental calcium as calcium
gluconate in critically ill children
B. The recommended dose is 1-2 mg/kg of calcium chloride. [Show Less]
