Which of the following is a common method for monitoring glucose levels in diabetes patients?

Blood glucose meters are a common method for monitoring glucose levels in diabetes patients because they provide immediate and accurate feedback. These devices measure the concentration of glucose in a small sample of blood, typically obtained from a finger prick. Monitoring blood glucose levels is crucial for diabetes management, as it allows patients to assess how well their diet, activity level, and medication are controlling their glucose levels throughout the day.

Using a blood glucose meter enables patients to make real-time adjustments to their diet and insulin administration, helping to prevent complications associated with both hyperglycemia and hypoglycemia. This method is widely used due to its convenience, portability, and the ability to obtain direct readings of blood glucose levels, which is essential for effective diabetes management.

In contrast, while urine tests can provide some information about glucose levels, they are not as precise or immediate as blood tests. Sputum analysis and breath tests are not relevant for monitoring glucose levels, as they are used for evaluating respiratory conditions and other metabolic functions, respectively. Thus, blood glucose meters are the preferred and most effective method for continuous glucose monitoring in individuals with diabetes.
