Final answer:
A person who has been administered Lispro (Humalog) should consume food within 15 minutes after injection to prevent hypoglycemia.
Step-by-step explanation:
For someone who receives an injection of Lispro (Humalog), a rapid-acting insulin, food should be given within 15 minutes post-injection. Lispro insulin works quickly to lower blood glucose levels by facilitating the uptake of glucose into cells after eating. Given its rapid onset of action, which typically begins within 15 minutes, delaying a meal could result in hypoglycemia (low blood sugar). Therefore, it is crucial to coordinate meal times closely with injections of Lispro to maintain proper blood glucose levels.
