With an 8 a.m. dose of the following insulin forms, followed by and inadequate dietary intake and/or excessive energy use, at approximately what time would hypoglycemia be most likely to occur?
Lispro
Approximately 8:30 to 9:30 a.m. (with peak of insulin dose)
With an 8 a.m. dose of the following insulin forms, followed by and inadequate dietary intake and/or excessive energy use, at approximately what time would hypoglycemia be most likely to occur?
Regular Insulin
Approximately 10 to 11 a.m. (with peak of insulin dose)

Because insulin glargine (Lantus) has no peak, an episode of hypoglycemia is unlikely. If hypoglycemia were to occur, the episode could be protracted if left untreated because of the protracted duration of activity of the medication.
