Which of the following are clinical manifestations of pyloric stenosis in the infant?
Projectile vomiting and abdominal pains
Weight gain and irritability
Frequent stools and bleaching
Edema and diarrhea
The Correct Answer is A
Choice A rationale
Pyloric stenosis is a condition that affects infants, typically between two and six weeks of age. The most common symptoms include projectile vomiting and persistent hunger, as the thickening of the pylorus prevents food from passing to the small intestines. Abdominal pain may also be present. Therefore, projectile vomiting and abdominal pains are clinical manifestations of pyloric stenosis in the infant.
Choice B rationale
While irritability can be a symptom of pyloric stenosis due to the infant’s discomfort, weight gain is not typically associated with this condition. In fact, weight loss or poor weight gains are more common due to the vomiting and reduced food intake.
Choice C rationale
Pyloric stenosis does not typically cause frequent stools or bleaching. In fact, fewer bowel movements may be observed because little food is passing to the small intestines.
Choice D rationale
Edema and diarrhea are not typical symptoms of pyloric stenosis. The primary symptoms are related to the obstruction of the stomach outlet, which includes projectile vomiting and persistent hunger.
