Final answer:
When a client with type 2 diabetes is admitted for elective surgery, regular insulin may be prescribed temporarily.
Step-by-step explanation:
When a client with type 2 diabetes is admitted for elective surgery, their health care provider may prescribe regular insulin even if oral antidiabetics were sufficient before hospitalization.
The nurse should teach the client that the addition of insulin is likely a temporary measure during their hospital stay (option B) since surgery can cause stress on the body and may impact blood sugar levels.
The nurse should also educate the client about potential side effects and risks of insulin therapy (option C), as well as provide information about the need for long-term insulin dependence (option D) if it is necessary in their case.
