The home health care nurse is caring for a 30-year-old woman with type I diabetes mellitus.
Correct answer
B
Rationale
Elevated morning blood glucose levels suggest the dawn phenomenon, where blood sugar rises in the early morning due to hormonal changes. Adding 3 units of NPH insulin at 10 PM addresses this by providing longer-acting insulin coverage. Reducing the diet, adding regular insulin, or eliminating the snack does not target the dawn phenomenon effectively.
