PALS Cardiac Arrest Algorithm 4

Question 1

A 4-year-old weighing 16 kg presents in VF. What is the correct initial defibrillation energy?

Accepted Answer

32 J

Answer

Initial defibrillation dose is 2 J/kg; for a 16 kg child, 2 × 16 = 32 J.

Question 2

Which of the following H's represents a common and correctable cause of pediatric cardiac arrest related to blood volume?

Accepted Answer

Hypovolemia

Answer

Hypovolemia is a common reversible cause of pediatric cardiac arrest and is treated with IV/IO fluid resuscitation.

Question 3

What is the correct epinephrine dose for a pediatric patient in cardiac arrest?

Accepted Answer

0.01 mg/kg IV/IO (max 1 mg)

Answer

Epinephrine for pediatric cardiac arrest is 0.01 mg/kg (1:10,000 solution) IV/IO, with a maximum single dose of 1 mg.

Question 4

After ROSC is achieved in a pediatric cardiac arrest patient, which post-resuscitation intervention is recommended to prevent secondary brain injury?

Accepted Answer

Targeted temperature management

Answer

Targeted temperature management (maintaining temperature between 32–37.5°C) is recommended post-ROSC to mitigate neurological injury.

Question 5

A rhythm check during CPR reveals organized electrical activity, but no pulse is felt. Which category does this rhythm fall into?

Accepted Answer

Non-shockable (PEA)

Answer

PEA is a non-shockable rhythm; the treatment is to continue high-quality CPR and identify reversible causes.
