Final answer:
The incorrect statement that an older child with type 1 diabetes made is believing they can eat whatever they want as long as they use sufficient insulin. This reflects a misconception about diabetes management, which requires careful monitoring of diet and understanding the glycemic impact of foods, not just insulin dosing.
Step-by-step explanation:
The statement by the older child that indicates a need for additional instruction on managing type 1 diabetes is: "I can eat whatever I want as long as I cover the calories with sufficient insulin." This statement is incorrect because managing type 1 diabetes involves more than just matching insulin to calorie intake. It's essential to have a balanced diet and to be mindful of how different foods can affect blood glucose levels. Eating whatever one wants without understanding the impact on blood glucose can lead to both short-term and long-term complications.
While it is true that people with type 1 diabetes must frequently check their blood sugar and take insulin injections to manage high blood sugar levels, the statement made by the child neglects the importance of following a balanced meal plan and considering the glycemic index of foods. Insulin dosing is complex and must take into account the types of foods eaten, exercise levels, and other factors.
In contrast, the other statements reflect a better understanding of diabetes management: Having a bedtime snack when taking NPH insulin might be appropriate to prevent nocturnal hypoglycemia; low-calorie drinks may fit into the meal plan if accounted for; and eating meals as scheduled is important to manage blood glucose levels effectively.
