Which statement by a patient with diabetes mellitus indicates an understanding of the medication insulin glargine (Lantus)?

  1. "Lantus causes weight loss."

  2. "Lantus is used only at night."

  3. "The duration of Lantus is six hours."

  4. "There is no peak time for Lantus."

The correct answer is: "There is no peak time for Lantus."

The correct answer is D. "There is no peak time for Lantus." Insulin glargine (Lantus) is a long-acting insulin that is used to help control blood sugar levels in patients with diabetes mellitus. Unlike short-acting insulins, Lantus does not have a pronounced peak time, meaning it works steadily over a longer duration to provide a more consistent level of insulin in the body. This is why it is often dosed once daily, usually at the same time each day, to help maintain stable blood sugar levels throughout the day and night. Options A, B, and C are incorrect because Lantus does not typically cause weight loss, is not used exclusively at night, and has a duration of action much longer than six hours.
