1. Which cardiac arrest rhythms does the healthcare provider correctly identify as
"nonshockable" rhythms?
Asystole
Pulseless electrical activity (PEA)
Ventricular fibrillation (VF)
Pulseless ventricular tachycardia (pVT)
*Answer
Asystole
Pulseless electrical activity (PEA)
*Explanation
Nonshockable rhythms are those for which defibrillation is not indicated. Asystole (flatline) and
PEA (organized electrical activity without a palpable pulse) are treated with high-quality CPR
and medications, not with a shock. VF and pVT are shockable rhythms.
2. A child in cardiac arrest presents with the ECG rhythm seen in the following image, but a
central pulse cannot be palpated. The provider correctly identifies this as which rhythm?
Torsades de pointes
Pulseless electrical activity (PEA)
Pulseless ventricular tachycardia (pVT)
Sinus bradycardia
*Answer
Pulseless ventricular tachycardia (pVT)
*Explanation
The description indicates a wide-complex tachycardia without a palpable central pulse. This
defines pulseless VT (pVT), a shockable rhythm. Torsades is a form of polymorphic VT, but the
term “pulseless ventricular tachycardia” is the correct identification when a pulse is absent.

, 3. Which neuroprotective measures should the provider implement after achievement of
return of spontaneous circulation (ROSC)?
Select all correct options that apply.
Prepare for prompt extubation.
Administer vasopressors.
Initiate targeted temperature management.
Optimize cerebral perfusion.
*Answer
Initiate targeted temperature management
Optimize cerebral perfusion
*Explanation
Post-ROSC neuroprotective strategies aim to reduce secondary brain injury. Targeted
temperature management (e.g., avoiding hyperthermia, induced hypothermia) and optimizing
cerebral perfusion (by maintaining adequate mean arterial pressure) are evidence-based.
Prompt extubation is not a neuroprotective measure, and vasopressors are used to support
perfusion but are not themselves primarily neuroprotective.
4. Which statement correctly describes the etiology of sudden cardiac arrest from an
arrhythmia in children and infants?
It is common in children, rare in infants.
It is common in children and infants.
It is rare in children and infants.
It is rare in children, common in infants.
*Answer
It is rare in children and infants.
*Explanation
Sudden cardiac arrest due to a primary arrhythmia (e.g., VF, VT) is uncommon in the pediatric
population. Most cardiac arrests in children and infants result from respiratory failure or shock
leading to hypoxic/asphyxial arrest rather than a sudden arrhythmic event.
