For an infant to have a score of 2 in reflex irritability, which response is expected?

A score of 2 in reflex irritability indicates that the infant is demonstrating a vigorous cry when stimulated. This scoring is part of the Apgar scoring system, which assesses the health of newborns shortly after birth. Reflex irritability is an important component as it reflects the infant's neurological function.

When an infant exhibits a vigorous cry, it indicates a robust response to stimuli, suggesting that the central nervous system is functioning effectively. This level of response is indicative of good health and optimal neurological status in the newborn.

The other potential responses, such as no response, a weak cry, or a grimace only, would not warrant a score of 2 in this context, as they indicate lesser levels of responsiveness, suggesting that the infant may not be in as good a condition regarding neurological function or overall health.
