A nurse is caring for an infant who has gastroesophageal reflux. The nurse should recognize that which of the following findings are associated with this condition? (Select all that apply.)

A. A rigid abdomen is not typical of gastroesophageal reflux and may indicate an acute surgical condition, such as intestinal obstruction or peritonitis, which requires urgent evaluation. B. Wheezing can occur if refluxed gastric contents are aspirated into the lungs, leading to respiratory complications such as chronic cough, recurrent pneumonia, or asthma-like symptoms. C. Fever is not a common manifestation of gastroesophageal reflux and usually points to infection or another systemic illness rather than reflux. D. Vomiting, or the regurgitation of stomach contents after feedings, is the hallmark symptom of gastroesophageal reflux in infants and often occurs after meals, sometimes accompanied by irritability or discomfort. E. Weight loss or poor weight gain can occur due to frequent vomiting, decreased caloric intake, or inadequate nutrient absorption, which can impact overall growth and development in infants.
