A 3-week-old infant is admited to the pediatric unit with vomiting and dehydration. The mother describes the infant as having projectile vomiting after eating. She also tells the practical nurse (PN) that the baby is always hungry. Which finding warrants immediate intervention by the PN?

Hyperactive gastric sounds.

Irregular palpable pulse.

Crying without tears.

Underweight for age.

Answer and Explanation

The Correct Answer is B

This finding may indicate a potential cardiac issue that needs immediate medical atention. Projectile vomiting and excessive hunger in a young infant may be signs of pyloric stenosis, a condition in which the muscle between the stomach and small intestine thickens, making it difficult for food to pass through.

Hyperactive gastric sounds may be present with vomiting, but it is not an immediate concern.

Crying without tears may be a sign of dehydration, but it is not an immediate concern.

Underweight for age is a concern but it is not a finding that requires immediate intervention.
