A nurse is reinforcing teaching about the manifestations of hyperglycemia with a client who has diabetes mellitus. Which of the following statements by the client indicates an understanding of the teaching?

A. "My breath may have a fruity odor.": Fruity breath can occur with diabetic ketoacidosis, a form of severe hyperglycemia, so this statement reflects accurate teaching. B. "I might experience blurry vision at times.": Fluctuating blood glucose can cause transient blurred vision, so this reflects accurate teaching. C. "I will be more thirsty than usual.": Increased thirst (polydipsia) is a classic sign of hyperglycemia and shows understanding of the teaching. D. "My appetite will be decreased.": Appetite often increases (polyphagia) with hyperglycemia; decreased appetite does not align with typical hyperglycemia teaching.
