Question

mealtime insulin should be given:
immediately after completing the meal
within 15 minutes of the meal
doesnt need to be given in relationship to the meal
both within 15 minutes of the meal or immediately after completing the meal are correct

Explanation:

Mealtime insulin is timed to match the rise in blood glucose from eating. Standard guidance states it should be administered within 15 minutes before or at the start of a meal, and in some cases (like for certain rapid-acting insulins or patients with delayed gastric emptying), it can be given right after a meal. This makes the combined option correct.

Answer:

Both within 15 minutes of the meal or immediately after completing the meal are correct
