The nurse is reviewing the patient's prescribed insulin regimen. The nurse notes that the physician has ordered a long-lasting insulin. Which medication will best meet this criteria?

A. Regular: Regular insulin is a short-acting insulin, typically used for mealtime glucose control. It has a short duration of action (4-6 hours) and is not considered long-lasting insulin. B. Insulin glargine (Lantus): Insulin glargine (Lantus) is a long-acting insulin that provides a steady release of insulin over a 24-hour period, without a peak, making it ideal for basal insulin coverage. It is designed to maintain blood glucose levels consistently throughout the day and night. C. Insulin aspart (NovoLog): Insulin aspart is a rapid-acting insulin used primarily for mealtime glucose control, and it has a short duration of action, usually around 2-4 hours. D. Insulin lispro (Humalog): Insulin lispro is a rapid-acting insulin that works quickly to control post-meal blood sugar but is not long-lasting. It typically lasts for about 3-5 hours.
