AND CORRECT VERIFIED ANSWERS WITH RATIONALE
ALREADY GRADED A+ NEW!!!!!!!!!!!!
This 300-question multiple-choice examination is a comprehensive
preparation resource for the Red Cross PALS (Pediatric Advanced Life
Support) Exam. It covers the full PALS algorithm, including the systematic
approach (initial impression, primary/secondary assessment, Evaluate-
Identify-Intervene), respiratory and shock emergencies, cardiac arrhythmias
(SVT, VT, VF, bradycardia, PEA/asystole), medication dosing (epinephrine,
adenosine, amiodarone, atropine, etc.), CPR/resuscitation techniques, post-
cardiac arrest care, and special populations (neonates, congenital heart
disease, anaphylaxis). Each question includes a detailed rationale reinforcing
evidence-based guidelines. This resource is ideal for healthcare professionals
preparing for PALS certification or recertification.
1. A child in cardiac arrest experiences return of spontaneous circulation but is
exhibiting signs of post-cardiac arrest syndrome (PCAS). The PALS resuscitation
team determines that the child is experiencing a systemic response to
ischemia/reperfusion. The team bases this determination on which finding(s)?
A) Hypotension, fever, hyperglycemia
B) Hypertension, hypothermia, hypoglycemia
C) Hypotension, hypothermia, hypoglycemia
D) Hypertension, fever, hyperglycemia
Answer: A
Rationale: Post-cardiac arrest syndrome (PCAS) is a systemic response to
ischemia/reperfusion. Findings include hypotension, fever, and hyperglycemia,
which are key indicators that guide post-resuscitation care .
2. A 5-year-old child with a history of a chronic neuromuscular disease is
experiencing respiratory distress. The child is breathing spontaneously and
receiving supplemental oxygen. Which additional intervention is a critical
component of airway management for this patient?
A) Administration of intravenous fluids
B) Airway clearance (e.g., suctioning)
C) Placement of a nasogastric tube
, D) Administration of bronchodilators
Answer: B
Rationale: In patients with neuromuscular disease, respiratory distress is often
complicated by ineffective cough and airway secretions. Airway clearance, such as
suctioning, is a critical intervention to maintain airway patency .
3. A child being cared for in the pediatric telemetry unit suddenly displays a
narrow-complex tachycardia on the ECG monitor. The provider prepares to
intervene because the child is demonstrating which type of arrhythmia?
A) Sinus tachycardia
B) Supraventricular tachycardia
C) Ventricular tachycardia
D) Atrial fibrillation
Answer: B
Rationale: Supraventricular tachycardia (SVT) is characterized by a narrow-
complex tachycardia. It requires prompt recognition and intervention to prevent
hemodynamic compromise .
4. An 11-year-old soccer player is brought to the emergency department. After a
quick assessment, the team realizes this patient is experiencing a severe asthma
exacerbation. Which medication would the team administer immediately?
A) Albuterol with or without ipratropium bromide
B) Methylprednisolone
C) Magnesium sulfate
D) Epinephrine
Answer: A
Rationale: In a severe asthma exacerbation, the immediate treatment is
bronchodilation with albuterol. Ipratropium bromide is often added to provide
additional relief and is recommended in the initial management of severe cases .
5. After ROSC, a child is experiencing post-cardiac arrest hypoperfusion. The
PALS resuscitation team would administer which element to restore intravascular
volume and optimize preload?
A) Hypertonic saline
B) Fresh frozen plasma
C) Isotonic fluid boluses
D) Packed red blood cells
Answer: C
, Rationale: Isotonic fluid boluses are administered to restore intravascular
volume and optimize preload in the setting of post-cardiac arrest hypoperfusion,
helping to stabilize the child's hemodynamics .
6. A 2-year-old child of unknown weight arrives at the emergency department in
cardiac arrest. When preparing to administer medications, which action would be
appropriate for the team to take?
A) Administer a standard adult dose
B) Estimate weight using a length-based resuscitation tape
C) Use a weight estimate based on the child's age
D) Delay medication administration until weight can be measured
Answer: B
Rationale: In an emergency, a length-based resuscitation tape (e.g., Broselow
tape) is the most accurate method to estimate a child's weight for medication
dosing and equipment selection when the actual weight is unknown .
7. A 4-year-old child is brought to the emergency department by the parents.
Assessment reveals that the child has only gasping respirations and the pulse rate is
65 beats per minute. Which action would the provider initiate first?
A) Deliver 1 BVM ventilation every 2 to 3 seconds
B) Begin chest compressions
C) Administer epinephrine
D) Place an advanced airway
Answer: A
Rationale: Gasping respirations with a heart rate below 60 beats per minute
indicates imminent cardiac arrest. The first action is to provide ventilations with a
bag-valve-mask (BVM) every 2 to 3 seconds while assessing the need for CPR .
8. The PALS team leader is conducting a debriefing session with the team. Which
topic(s) would the team leader most likely address during the session?
A) Discussion of the pros and cons of the interventions, evaluation of the
objective data gathered, summary of the event, and identification of ways to
improve
B) Assigning blame for errors
C) Reviewing hospital policy only
D) Discussing the patient's family's reaction
Answer: A
Rationale: Debriefing is a crucial part of resuscitation to improve team
performance. It includes a discussion of the pros and cons of interventions,
, evaluation of objective data, a summary of actions taken, and identification of
areas for improvement .
9. The PALS resuscitation team notes a wide-complex tachycardia on the ECG
monitor and the child does not have a pulse. The team prepares to intervene to
address which arrhythmia?
A) Torsades de pointes
B) Supraventricular tachycardia
C) Monomorphic pulseless ventricular tachycardia
D) Atrial fibrillation
Answer: C
Rationale: Pulseless ventricular tachycardia (VT) is a wide-complex tachycardia
without a pulse. Torsades de pointes is a specific type of polymorphic VT, but the
question points to monomorphic VT if the ECG waveform is consistent with that.
The key is the recognition of a pulseless wide-complex tachycardia .
10. What is the correct IV/IO dose of epinephrine for a pediatric patient in cardiac
arrest?
A) 0.1 mg/kg every 3 to 5 min (max single dose 1 mg)
B) 0.01 mg/kg every 3 to 5 min (max single dose 1 mg)
C) 0.1 mg/kg every 3 to 5 min (max single dose 10 mg)
D) 0.01 mg/kg every 3 to 5 min (max single dose 10 mg)
Answer: B
Rationale: The correct IV/IO dose of epinephrine for a pediatric patient in
cardiac arrest is 0.01 mg/kg (0.1 mL/kg of the 1:10,000 concentration) every 3 to 5
minutes, with a maximum single dose of 1 mg .
11. Assessment of a 3-month-old infant admitted with respiratory distress reveals
fever, grunting, and a wet, "junky" cough. The infant's parents said the child had a
recent respiratory infection with a fever. A rapid respiratory syncytial virus (RSV)
test is positive. Which condition would the provider most likely suspect as the
cause?
A) Croup
B) Pneumonia
C) Bronchiolitis
D) Epiglottitis
Answer: C
Rationale: Bronchiolitis is a common lower respiratory tract infection in infants,
often caused by RSV. Typical signs include fever, cough, grunting, and wheezing .
