On assessment, which data would the nurse expect to obtain when asking the parents about the infant's symptoms related to pyloric stenosis? Select all that apply.

Choice A rationale Watery diarrhea is a symptom of conditions like gastroenteritis or malabsorption, but it is not a characteristic finding in pyloric stenosis. The typical symptom related to gastric output is projectile, non-bilious vomiting due to the obstruction at the pylorus. Choice B rationale Persistent, forceful, non-bilious vomiting in pyloric stenosis prevents fluids and electrolytes from entering the small intestine for absorption. This results in significant fluid loss, leading to clinical signs of dehydration, such as poor skin turgor and depressed fontanelles. Choice C rationale Despite the vomiting, infants with pyloric stenosis remain hungry because the formula or breast milk is immediately expelled before any significant caloric absorption can occur. The child has an empty stomach and rapidly resumes feeding attempts shortly after vomiting. Choice D rationale Coughing is not a direct symptom of pyloric stenosis. While a cough could be a sign of a separate respiratory issue or aspiration from vomiting, it is not a primary or expected finding directly attributable to the hypertrophied pylorus. Choice E rationale Due to the forceful vomiting and resulting dehydration, the infant's body attempts to conserve fluid, which leads to decreased urine output (oliguria), not increased urine output. Decreased urine output is a key clinical sign of fluid deficit in this condition. Choice F rationale Ribbon-like stools are characteristic of lower gastrointestinal issues, often associated with Hirschsprung's disease, due to an obstruction or spasm in the large intestine. Pyloric stenosis is an obstruction of the gastric outlet, which does not cause this type of stool change.
