Explanation
While assessing the child, the nurse recognizes that sweet breath odor, dry mucous membranes, and poor weight gain are signs of diabetes mellitus, a possible diagnosis. The nurse anticipates the provider will order the following tests: urinalysis and blood sugar to help confirm or rule out the diagnosis.
Rationale:
Sweet breath odor: A fruity or sweet odor, often described as acetone-like, is a classic sign of diabetic ketoacidosis (DKA), a complication of diabetes mellitus. This occurs due to the breakdown of fats in the absence of sufficient insulin, producing ketones that are exhaled.
Dry mucous membranes: This is a common sign of dehydration, which can be caused by hyperglycemia in diabetes mellitus. High glucose levels lead to increased urine output and fluid loss.
Poor weight gain: Children with diabetes mellitus type 1 often experience unexplained weight loss despite increased appetite (polyphagia) because their bodies break down fat and muscle for energy due to insufficient insulin.
Most Likely Diagnosis:
Diabetes mellitus: The combination of symptoms (sweet breath odor, dry mucous membranes, and poor weight gain) strongly suggests diabetes mellitus, likely type 1 diabetes. This condition often presents with hyperglycemia, dehydration, and weight loss despite increased hunger.
Tests to Confirm or Rule Out the Diagnosis:
Urinalysis: This is used to check for the presence of glucose and ketones in the urine, which can help diagnose diabetes mellitus and diabetic ketoacidosis (DKA).
Blood sugar: A blood glucose test is essential for confirming diabetes mellitus. Elevated blood glucose levels are a hallmark of the disease, and testing will provide insight into the child’s current glucose levels, confirming or ruling out diabetes.
Correct Answer is B
Explanation
Breastfeeding is actually encouraged for infants with congenital heart disease because it provides easier digestibility, better nutrition, and helps with bonding. It also offers optimal growth and development in most cases. Bottle-feeding, on the other hand, might require more energy and can be more difficult for infants with CHD, which is why breastfeeding is often preferred when possible.
