Which measure would be most effective in aiding bronchodilation in a child with laryngotracheobronchitis (Croup)?

The correct answer is Choice A.

Choice A rationale

Testing the urine for ketones is essential for managing type 1 diabetes, especially during illness. Ketones are produced when the body breaks down fat for energy due to insufficient insulin. High levels of ketones can lead to diabetic ketoacidosis, a serious condition that requires immediate medical attention.

Choice B rationale

While notifying the provider if blood glucose levels are over 350 mg/dL is important, it is not the most immediate action required during illness management. High blood glucose levels can indicate poor diabetes control, but ketone testing is more critical during illness to prevent ketoacidosis.

Choice C rationale

Withholding insulin when feeling nauseous is incorrect. Insulin should not be withheld during illness, as blood glucose levels can increase due to stress or infection. Continuing insulin administration is crucial to prevent hyperglycemia and ketoacidosis.

Choice D rationale

Limiting fluid intake during mealtime is not recommended. Proper hydration is essential for overall health and helps manage blood glucose levels. Fluids should be consumed as needed, especially during illness.

The correct answer is Choice A.

Choice A rationale

Projectile vomiting is a hallmark symptom of pyloric stenosis. It occurs due to the obstruction at the pylorus, causing forceful expulsion of stomach contents. This symptom typically appears in infants between 3 to 6 weeks of age.

Choice B rationale

A rigid abdomen is not a typical symptom of pyloric stenosis. It may indicate other abdominal issues, such as peritonitis or bowel obstruction.

Choice C rationale

Red currant jelly stools are associated with intussusception, not pyloric stenosis. Intussusception involves the telescoping of one part of the intestine into another, leading to bowel obstruction and characteristic stool appearance.

Choice D rationale

Distended neck veins are not related to pyloric stenosis. This symptom is more commonly associated with cardiac conditions or severe respiratory distress.
