A client with type 2 diabetes mellitus (DM) is being discharged after treatment for an acute bronchitis infection. The nurse is providing teaching for medications to be taken at home, which includes a new prescription for self-administered glargine insulin 20 units SUBQ at bedtime. The client asks if they now have type 1 diabetes mellitus. How should the nurse respond?

Offer support while explaining that acute illness can change the type of diabetes and its treatment.

Advise the client that the insulin will be discontinued when the glycosylated haemoglobin A1C levels reflect good control.

Remind the client that DM is a chronic progressive disease and lifelong insulin is usually needed.

Explain that the insulin injections will probably be discontinued once stress and illness are resolved.
