Question

question 4 of 44
which is the most common cause of cardiac arrest in children?
cardiac problem
congenital or acquired heart defect
respiratory failure or shock
infection and sepsis

Explanation:

In children, cardiac arrest usually occurs due to problems in the respiratory or circulatory systems. Respiratory failure can lead to hypoxia, and shock can cause insufficient blood flow. These factors disrupt the body's normal function and are more common causes of cardiac arrest in children compared to primary cardiac problems (which are less frequent in this age group), congenital/acquired heart defects (not the most common trigger for arrest in general pediatric populations), or infection/sepsis (while serious, not as immediately linked to the most common cause of arrest as respiratory - shock issues).

Answer:

Respiratory failure or shock.
