For a 15-year-old with type 1 diabetes experiencing morning hyperglycemia due to the dawn phenomenon, increasing the insulin dosage at bedtime is a sound adjustment. The dawn phenomenon refers to a natural increase in blood glucose levels that occurs in the early morning hours due to hormonal changes, particularly the release of counter-regulatory hormones like cortisol and glucagon that increase insulin resistance.

By increasing the bedtime insulin, the patient can better manage the elevated blood glucose levels that occur during this time. This adjustment helps to ensure that there is sufficient insulin in the system to counteract the rise in glucose that typically happens in the early morning.

Other options do not adequately address the underlying issue related to the dawn phenomenon. Testing blood glucose levels at 3:00 AM may provide information on nighttime levels but does not modify the treatment to prevent morning hyperglycemia. Reducing insulin dosage could worsen hyperglycemia, and testing in the evening may not offer specific insights into overnight changes that are crucial for managing morning glycemic levels.
