6-week-old infant with hypertrophic pyloric stenosis
Question 1 of 5
A nurse is caring for a 6-week-old infant who has hypertrophic pyloric stenosis (HPS). Which of the following clinical manifestations should the nurse expect?
Correct Answer: D
Rationale: The correct answer is D: Projectile vomiting. In hypertrophic pyloric stenosis, the infant's pyloric muscle thickens, causing obstruction at the stomach's exit. This leads to forceful, non-bilious vomiting after feedings. Rigid abdomen (
A) is not typically seen in HPS but may occur in other conditions like intussusception. Distended neck veins (
B) are not a common manifestation of HPS. Red currant jelly stools (
C) are associated with intussusception, not HPS. Other choices are not relevant to HPS.
