A student's glucose level before PE class is found to be 316 mg/dL. What is the appropriate action to ensure safe exercise?

When a student has a glucose level of 316 mg/dL, it indicates hyperglycemia, which can elevate the risk of complications during physical exercise. Checking for the presence of ketones is crucial because high glucose levels can lead to the body starting to break down fat for energy, resulting in the production of ketones. If ketones are present, this could signify the onset of diabetic ketoacidosis (DKA), a serious condition that can be exacerbated by exercise.

Exercise can further increase blood glucose levels in some cases and worsen the state of ketosis if ketones are present. Therefore, determining if ketones are present is a critical step to ensure the student can safely participate in physical activities. Only if the ketone test shows negative results or indicates a safe level, can a decision about exercising be properly made. This proactive approach helps manage potential risks and prioritizes the student's health during physical activity.
