Final answer:
The onset of action for insulin glulisine is typically within 15 to 30 minutes, therefore the nurse should anticipate the insulin effect to start approximately at 0745, which is 15 minutes after administration at 0730.
Step-by-step explanation:
The question pertains to the pharmacokinetics of a rapid-acting insulin analog, insulin glulisine, which a nurse is administering to an adolescent patient with type 1 diabetes mellitus. Insulin glulisine typically has an onset of action within 15 to 30 minutes.
Given that the nurse administers the insulin at 0730, the onset of the insulin action would be anticipated generally around 0745 to 0800. This is due to insulin's role in facilitating glucose uptake by the cells shortly after administration, thus decreasing blood glucose levels following a meal. Consequently, the correct answer is B. 0745 as it falls within the expected onset time window for insulin glulisine.
