A client with acute lymphociytic leukemia is also a diabetic. Sliding scale reveals the need to administer lispro (Humalog) Insulin 10 units subcutaneously for the 12 PM dose. When should the lunch meal arrive? A. 1 hour after administration B. Within 30 minutes of administration C. No food necessary with this drug D. Food should be available when administered

Lispro (Humalog) is a type of rapid-acting insulin, which begins to work very quickly after injection, typically within 15 minutes. It works to lower the blood glucose levels by helping cells to uptake glucose from the bloodstream. Since it is a rapid-acting insulin, it is essential to consider the timing of the client's meal in relation to the insulin administration.

Option A suggests that the meal arrives 1 hour after the administration. However, given that lispro insulin is rapid-acting, waiting for 1 hour would mean that the insulin would have started working, and blood sugar could fall to dangerously low levels before the client has had a meal to balance it out. This option is not ideal. Option C suggests that no food is necessary with this drug. This is incorrect because insulin administration should always be accompanied by a meal to ensure proper blood sugar management. Without the meal, the client would be at risk of developing hypoglycemia (low blood sugar). Option D states that food should be available when administered. Although the food should be available close to the time of administration, having it available at the same time may not give the insulin a sufficient amount of time to start working. It's essential to find a balance between the insulin's onset and the meal timing to prevent low blood sugar.

Option B suggests that the meal should arrive within 30 minutes of administration. This option appears to be the most reasonable, given the rapid-acting nature of the insulin lispro. Having the meal arrive within this 30-minute timeframe allows the insulin to start working, and the client can start consuming the meal. This timing helps maintain a balance between insulin administration and blood sugar control. Thus, the correct answer is: B. Within 30 minutes of administration
