Final answer:
In a graded exercise test, blood glucose levels are typically not monitored; whereas heart rate, blood pressure, and oxygen saturation are common variables that are assessed.
Step-by-step explanation:
The answer to the question “Which of the following are typically not monitored during a graded exercise test?” is D) Blood glucose levels. During a graded exercise test, it is common to monitor variables that reflect the cardiovascular and respiratory responses to increasing physical activity. These include heart rate, blood pressure, and oxygen saturation. Monitoring blood glucose levels is not typically included unless the test is specifically designed to assess the impact of exercise on glucose metabolism in individuals with diabetes or other metabolic conditions.
