Which statement about exercise management for diabetic patients is incorrect?

1. "I will check my blood glucose prior to exercise if it is less than 200."

2. "I plan on exercising for an extended period and will check my blood glucose regularly."

3. "My blood glucose is 268 and I have ketones, so I will avoid exercising today."

4. "All of the options are correct statements."

The correct answer is: "I will check my blood glucose prior to exercise if it is less than 200."

The statement regarding checking blood glucose prior to exercise when it is less than 200 is incorrect because, for the safety of diabetic patients, it is generally advised that they should check their blood sugar before exercise, especially if it is above 250 mg/dL. If the blood glucose level is between 100 mg/dL and 250 mg/dL, moderate exercise can be safely performed, provided the individual feels well. However, if the blood glucose is over 300 mg/dL, particularly if ketones are present, exercise is typically advised against due to the risk of complications such as diabetic ketoacidosis. The other options present appropriate guidelines for exercise management in diabetic patients. Planning to check blood glucose regularly during extended exercise is sensible, as it helps in managing potential fluctuations in blood glucose levels. Additionally, avoiding exercise when the blood glucose is 268 with ketones is prudent, as exercising in such a state can exacerbate complications. The final statement about all options being correct is also valid, as it assesses the accuracy of exercise management statements. Thus, the incorrectness of the first statement regarding checking blood glucose before exercise when it is under 200 leads to it being identified as the exception among sound practices for managing exercise in diabetic patients.
