Correct Answer is A
Explanation
A. Carbohydrate coverage: Samantha's meal includes 60g of carbs, which is 4 carb exchanges (60g ÷ 15g). She needs 4 units of Novolog for the carbohydrates. Correction dose: Since her glucose level is 329mg/dl, it falls within the 300-349mg/dl range, so she needs 1 unit of Novolog for correction. Total insulin = 4 units (meal coverage) + 1 unit (correction) = 5 units Novolog.
B. 5.5 units novolog: This would be incorrect because it adds an extra 0.5 units without a clear justification based on either the carbohydrate coverage or the blood glucose correction scale.
C. 4 units novolog: This is incorrect because it only accounts for the insulin needed to cover the carbohydrates in the meal and does not include the necessary 1-unit correction for her elevated blood glucose level.
D. 2.5 units novolog: This is incorrect as it significantly underestimates the insulin needed for both meal coverage and blood glucose correction. It doesn't accurately reflect either the carbohydrate content of the meal or the correction needed based on the provided scale.

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.
