A nurse is teaching a client who has diabetes mellitus and a new prescription for a combination of lispro insulin and NPH insulin. Which of the following statements by the client indicates an understanding of the teaching?

A. "I should eat within 1 hour after my injection.": Lispro insulin is a rapid-acting insulin that typically requires eating within 15 minutes after administration, not within 1 hour. This timing helps prevent hypoglycemia after the insulin’s peak action. B. "I will expect the lispro insulin to be cloudy.": Lispro insulin is a clear solution, not cloudy. NPH insulin, which is an intermediate-acting insulin, is the cloudy insulin. This statement reflects a misunderstanding of the appearance of the insulins. C. "I should draw up the NPH insulin first.": When mixing insulins, the short-acting insulin (lispro) should be drawn up first to avoid contaminating the vial of rapid-acting insulin with the longer-acting NPH insulin. The correct order is to draw up the clear (lispro) insulin first, followed by the cloudy (NPH) insulin. D. "I will mix these medications in one syringe.": It is correct to mix rapid-acting (lispro) and intermediate-acting (NPH) insulins in one syringe. This combination helps provide both immediate and sustained blood glucose control.
