A nurse is caring for a 6-week-old infant diagnosed with pyloric stenosis. Which of the following clinical manifestations should the nurse expect?

A. Distended neck veins are typically seen in cases of heart failure or other circulatory issues, not pyloric stenosis. B. Red currant jelly stools are associated with intussusception, not pyloric stenosis. C. Weight loss is a common manifestation of pyloric stenosis due to vomiting and poor nutrient intake. This occurs as the narrowing of the pylorus obstructs the passage of food. D. Occasional vomiting could be a sign of pyloric stenosis, but the hallmark feature is projectile vomiting, which occurs more frequently and is often more forceful.
