A patient diagnosed with diabetes is being discharge to home with regular insulin and insulin glargine (Lantus). During discharge teaching the patient asks what is the difference between the 2 types of insulin. What is your best response?

"Insulin glargine will only be given if her blood sugars are higher than 200 mg/dL."

"Insulin glargine is the same as regular insulin, and she will require several injections during the day."

"Insulin glargine helps to manage elevated blood sugars after she eats, and she will require injections three times a day."

"Insulin glargine will help control her blood sugar for 24 hours and will need to be given one time per day."
