The nurse is evaluating a diabetic client's understanding of the signs of hyperglycemia. Which statement by the client reflects an understanding?

Fatigue, dry skin, polyuria, and polydipsia are classic symptoms of hyperglycemia. Fatigue occurs because of lack of energy from the inability of the body to use glucose. Dry skin occurs secondary to dehydration related to polyuria. Polydipsia occurs secondary to fluid loss. Diaphoresis is associated with hypoglycemia. A client should not take extra hypoglycemic agents to reduce an elevated blood glucose level. A client with hyperglycemia becomes dehydrated secondary to the osmotic effect of the elevated glucose; therefore, the client must increase fluid intake.
