A nurse is caring for a male infant who has a palpable mass in the upper right quadrant and stools mixed with blood and mucus. The nurse should recognize that which of the following diagnoses is associated with these findings?

Choice A reason: This statement is incorrect, as giving an oral rehydration solution to an infant who is projectile vomiting may worsen the dehydration and electrolyte imbalance. The nurse should advise the parent to stop feeding the infant and seek medical attention.

Choice B reason: This statement is incorrect, as burping the baby more frequently during feedings may not prevent the projectile vomiting, which is caused by a mechanical obstruction of the stomach, not by air swallowing. The nurse should assess the parent for signs of pyloric stenosis, such as a palpable olive-shaped mass in the right upper quadrant of the abdomen.

Choice C reason: This statement is correct, as bringing the baby in to the clinic today is the best course of action for an infant who is projectile vomiting, which is a sign of a serious condition such as pyloric stenosis, a narrowing of the opening between the stomach and the small intestine. The nurse should inform the parent that the infant needs immediate evaluation and treatment to prevent complications such as dehydration, malnutrition, and metabolic alkalosis.

Choice D reason: This statement is incorrect, as trying switching to a different formula may not help the infant who is projectile vomiting, which is not related to the type of formula, but to a structural problem in the gastrointestinal tract. The nurse should not suggest changing the formula without consulting the provider.

Choice A reason: This statement indicates a need for clarification, as sodium biphosphate/sodium phosphate is a laxative that can cause bowel perforation in a child with appendicitis. The nurse should question this prescription and avoid giving it to the child.

Choice B reason: This statement is correct, as maintaining NPO status is a standard intervention for a child with suspected appendicitis. It prevents further irritation of the appendix and prepares the child for possible surgery.

Choice C reason: This statement is correct, as monitoring oral temperature every 4 hours is a way to assess for signs of infection and inflammation in a child with suspected appendicitis. The nurse should also monitor for other symptoms such as abdominal pain, nausea, vomiting, and rebound tenderness.

Choice D reason: This statement is correct, as medicating the client for pain every 4 hours as needed is a way to provide comfort and relief for a child with suspected appendicitis. The nurse should use a pain scale to evaluate the effectiveness of the medication and report any changes in the pain level or location.
