A nurse is teaching a school-age child who has type 1 diabetes mellitus and his parents about illness management. Which of the following instructions should the nurse include?

A) "Limit fluid intake during mealtime":

Limiting fluid intake during meals is not a standard practice for managing type 1 diabetes. Proper hydration is important for overall health, and fluids should be consumed as needed.

B) "Notify the provider if blood glucose levels are over 350 milligrams/deciliter":

Blood glucose levels over 350 mg/dL can indicate hyperglycemia, which requires prompt attention. High blood glucose levels can lead to complications if not addressed promptly. Contacting the healthcare provider is an appropriate step. However, consistent Blood Glucose Levels Above 240 mg/dL (13.3 mmol/L) or presence of symptoms like frequent urination, thirst, blurry vision, or fatigue) are concerning. The client should have contacted the health care provider by this point. 

C) "Test the urine for ketones":

Testing urine for ketones is an important instruction. Ketones are produced when the body breaks down fat for energy, often in the absence of sufficient insulin. High ketone levels can indicate diabetic ketoacidosis (DKA), a serious complication. Regular ketone testing, especially during illness or high blood glucose levels, helps monitor for DKA.

D) "Withhold insulin dose if feeling nauseous":

This instruction is not accurate. Nausea could be a sign of various conditions, including illness. Insulin should not be withheld without consulting a healthcare provider. Managing insulin doses appropriately is crucial to maintaining blood glucose control
