PALS Precourse Test Questions And Verified DetailedAnswers Latest Update
Parents of a 1-year-old female call EMS after picking up their daughter from the
babysitter. In the initial impression, the paramedics find an obtunded infant who is
breathing irregularly, with bruises over the abdomen, abdominal distension, and
cyanosis. They start assisted bag-mask ventilation with 100% oxygen. On the primary
assessment, the heart rate is 36/min, peripheral pulses cannot be palpated and central
pulses are barely palpable. The cardiac monitor shows sinus bradycardia. Chest
compressions are begun 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. 20 mL/kg rapid bolus of isotonic crystalloid
D. 0.02 mg/kg atropine IV

You enter a room to do an initial impression on a previously stable 10-year-old male and
find him unresponsive and apneic. You call a code and perform bag-mask ventilation
with 100% oxygen. The cardiac monitor shows you a wide-complex tachycardia. He has
no detectable pulses so compressions and ventilations are given. 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. On the next rhythm check, you have VF still present. You deliver another
4 J/kg shock and reinstate CPR. According to the PALS Pulseless Arrest Algorithm, the
next drug and dose due after restarting CPR is?
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
D
The best answer is D.
Which of the following statements regarding calcium is correct?
A. Calcium chloride 10% has equivalent bioavailability of elemental calcium to calcium
gluconate in critically ill children
B. The dose is 1-2 mg/kg of calcium chloride.
C. Indications for the use of calcium include hypercalcemia, hypokalemia and
hypomagnesemia.
D. Calcium should not be routinely given during cardiac arrest.

Initial impression of a 9-year-old male with increased work of breathing reveals the boy
to be agitated and leaning forward on the bed with obvious respiratory distress. You
administer 100% oxygen by nonrebreathing mask. 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. His SpO2 is 96% (on nonrebreathing
mask). What is the next medical therapy to provide to this patient?
, A. Adenosine 0.1 mg/kg
B. Amiodarone 5 mg/kg IV/IO
C. Albuterol by nebulization
D. Procainamide 15 mg/kg IV/IO

You are called to resuscitate an infant who has severe symptomatic bradycardia
associated with respiratory distress. An effective airway, oxygenation, and ventilation
have been established, but the bradycardia persists. There is no heart block present.
Which of the following is the first drug you should administer?
A. Dopamine
B. Adenosine
C. Atropine
D. Epinephrine

An infant has a history of vomiting and diarrhea and arrives by ambulance. On your
initial examination, the newborn responds only to painful stimulation. The airway is
patent, the respiratory rate is 40/min with good symmetric breath sounds, and the infant
