A nurse is reinforcing teaching with a client who has diabetes mellitus and a new prescription for glargine Lantus® insulin. Which of the following statements by the client indicates an understanding of the teaching?

A. Glargine (Lantus®) is a long-acting insulin and should not be shaken; shaking can cause bubbles and affect the dose. B. The thigh is slower for absorption compared with the abdomen; for glargine, injection site rotation is important, but rapid absorption is not the goal. C. Unopened vials of insulin should be stored in the refrigerator (36–46°F / 2–8°C) to maintain potency until first use. D. Glargine is long-acting and provides a basal level of insulin; it should be administered once daily at the same time, not immediately before meals.
