Which statement indicates a lack of understanding about the purpose of self-monitoring blood glucose?

1. "I test my blood glucose whenever I feel bad, even if it's not my scheduled time to check"

2. "I test 2-3 times a day and schedule my testing for when I think my numbers will be the best"

3. "I wake up at 3 AM and test whenever my doctor changes my basal insulin dose"

4. "I try to test a couple of hours after a meal to see if my insulin dose was correct"

The correct answer is: "I test 2-3 times a day and schedule my testing for when I think my numbers will be the best"

The statement that suggests a lack of understanding about the purpose of self-monitoring blood glucose is one that indicates testing is conducted based solely on when the individual anticipates good results, rather than adhering to a consistent testing schedule that provides reliable data for managing diabetes. Self-monitoring of blood glucose (SMBG) is most effective when it is performed regularly and at appropriate times to capture the overall blood glucose patterns and responses to factors like diet, medication, and physical activity. Testing only during periods expected to yield favorable results undermines the objective of identifying problem areas or periods of hyperglycemia or hypoglycemia, which is crucial for effective diabetes management. Regular and strategic timing of blood glucose checks enhances the understanding of how the body reacts to different circumstances rather than selectively testing when outcomes are anticipated to be optimal.
