A client has been diagnosed with type 1 diabetes mellitus. When teaching the client and family how diet and exercise affect insulin requirements, the nurse should include which guideline?
Correct Answer: B
Rationale: When a client with type 1 diabetes mellitus exercises or reduces their food intake, it can lead to a decrease in blood glucose levels. This is because the body is using up glucose for energy during exercise or receiving less glucose from food intake. As a result, the client would require less insulin to manage their blood glucose levels, since there is less glucose present in the bloodstream that needs to be regulated. It is important for the client and family to understand this relationship between diet, exercise, and insulin requirements to effectively manage the client's diabetes.
