The nurse is caring for a client with type 1 diabetes mellitus who reports experiencing diaphoresis and shakiness in the early morning hours. The nurse should expect which change in the client's treatment plan?

A. An OGTT is not directly related to the symptoms of hypoglycemia experienced in the early morning.B. An insulin pump is a possible treatment but is not the immediate change needed for managing hypoglycemia.C. Diaphoresis and shakiness in the morning suggest possible nocturnal hypoglycemia, which may require a decrease in the evening dose of NPH insulin to prevent such episodes.D. Testing glucose levels at multiple times can be part of managing diabetes but does not address the immediate need for adjustment in insulin dosing.
