Which patient statement indicates a misunderstanding in the administration of insulin glargine?

The statement indicating a misunderstanding in the administration of insulin glargine is that the patient plans to take this insulin right before meals. Insulin glargine is a long-acting insulin that provides a steady level of insulin with no pronounced peak, which is typically administered once a day at the same time, irrespective of meals. Its purpose is to provide a baseline level of insulin to control blood glucose levels throughout the day and night.

Taking insulin glargine right before meals is not appropriate, as this type of insulin is not designed to cover the immediate glucose rise from food intake. Instead, patients requiring coverage for meals would usually be prescribed a rapid-acting insulin, which acts quickly to manage postprandial (after meal) blood glucose spikes. Therefore, the misunderstanding lies in the timing and purpose of the administration of this long-acting insulin.

In contrast, other statements reflect accurate information regarding insulin glargine administration or handling. For example, it is common to gently roll vials of insulin to mix them, although this is more relevant for certain types of insulin rather than glargine, which is typically not mixed due to its formulation. The statement about the duration of glucose control for 24 hours aligns with the pharmacokinetics
