A 7-year-old child is admitted to the hospital with a diagnosis of acute rheumatic fever. In obtaining a health history from the child's mother, the recent occurrence of which illness is most significant?

Projectile vomiting in a 5-week-old infant can be indicative of a condition known as pyloric stenosis. Pyloric stenosis is a narrowing of the pylorus, the opening from the stomach to the small intestine. It results in delayed gastric emptying, leading to the forceful, projectile vomiting observed after feedings.

A. An olive-size mass in the epigastric area is a characteristic finding in infants with pyloric stenosis. The hypertrophied pyloric muscle feels like an olive and is often palpable in the upper abdomen.

B. Stool that consists of mucus and blood is not a typical finding associated with pyloric stenosis. This symptom is more suggestive of gastrointestinal issues like infectious colitis or other conditions unrelated to pyloric stenosis.

C. Rebound tenderness in the left lower abdominal quadrant is not a common finding in infants with pyloric stenosis. Rebound tenderness is typically associated with conditions like appendicitis in a different part of the abdomen.

D. Frequent burping accompanied by poor feeding can be a sign of discomfort but is not a specific indicator of pyloric stenosis. Projectile vomiting is a more distinctive symptom associated with this condition.

A. Understanding the quality control process used to troubleshoot the pump is important, but it is a secondary assessment and educational component. The primary focus should be on the child's ability to operate the pump effectively.

B. Interpretation of fingerstick glucose levels is important for diabetes management, but it does not specifically address the use of an insulin pump.

C. Knowledge of glycosylated hemoglobin A1c levels is valuable for assessing long-term glycemic control but is not the primary assessment needed when considering the transition to an insulin pump.

D Ability to program the pump for basal insulin with mealtime boluses.

When a child with type 1 diabetes mellitus expresses an interest in using an insulin pump, the most important assessment is their ability to program and manage the pump effectively. The nurse should assess whether the child and their family have the knowledge and skills to use the pump, including setting basal insulin rates and delivering mealtime boluses. The successful use of an insulin pump requires a good understanding of its operation and the ability to make adjustments based on the child's specific needs and glucose levels.

The ability to manage the insulin pump effectively is essential to ensure safe and appropriate diabetes management, making it the most important assessment in this context.
