A client with diabetes mellitus is admitted with an upper respiratory infection (URI). Which changes in blood glucose management should the nurse tell the client to expect?

Choice A reason: Illness often causes blood glucose fluctuations due to stress hormones. Fewer glucose checks would risk missing hyperglycemia or hypoglycemia, making this an unsafe recommendation. Choice B reason: Restricting caloric intake during illness may lead to hypoglycemia, especially if insulin doses are maintained. Nutritional support is vital during infection. Choice C reason: Increased oral fluid intake is encouraged to prevent dehydration and support metabolic function, but it does not directly address glucose management. Choice D reason: Illness-induced stress can elevate blood glucose levels, often requiring temporary increases in insulin dosage to maintain glycemic control and prevent complications like diabetic ketoacidosis.
