Final answer:
The school nurse should advise the student to have a snack such as six graham crackers or a cup of orange juice before practice to prevent hypoglycemia. Regular checking of blood sugar, maintaining prescribed insulin injections, and staying hydrated are also important in the management of type 1 diabetes during increased physical activity.
Step-by-step explanation:
The school nurse should instruct the adolescent with type 1 diabetes mellitus to eat six graham crackers or drink a cup of orange juice prior to practice or game time. This snack will help prevent hypoglycemia, which can be caused by increased physical activity like cheerleading practice. It's crucial for individuals with type 1 diabetes to maintain a balance of food intake and insulin to manage their blood glucose levels, especially during periods of heightened activity.
Other recommendations for managing diabetes during school activities might include checking blood sugar levels frequently, carrying quick sources of glucose such as candy or glucose tablets, and making sure peers or coaches are aware of the diabetes management plan.
It is also important to continue regular meals and insulin injections as prescribed, as well as stay hydrated. The misconception that insulin injections should be avoided on practice or game days is incorrect, as insulin is necessary for the body to utilize glucose properly, even during periods of increased activity.
