Give the client a concentrated carbohydrate.
The family of a client in the hospital with diabetes mellitus that is out of control asks the nurse to explain the client's recent weight loss while eating more than usual. How will the nurse respond?
Glucose is unused without insulin, so body fats are used for energy.
