Final Answer:
A fasting period of 8 hours is crucial for accurate Glucose Tolerance Test (GTT) results, establishing a stable baseline for glucose levels. This practice aligns with standard protocols, ensuring reliable assessments of glucose metabolism.Thus option c is the correct option.
Step-by-step explanation:
A patient undergoing a Glucose Tolerance Test (GTT) should fast for at least 8 hours before the test. This is crucial for accurate results as it helps in assessing the body's ability to regulate glucose levels. Fasting allows the baseline blood glucose levels to be established, providing a clear reference point for evaluating how the body responds to a glucose load. A longer fasting period, such as 8 hours, ensures that the patient's digestive system is in a rested state, preventing interference with the test results.
Fasting for 8 hours is a well-established standard practice for GTT because it allows sufficient time for the body to reach a stable fasting state. This period is considered optimal as it ensures accurate measurement of glucose metabolism without the influence of recent food intake. Longer periods of fasting may lead to hypoglycemia, while shorter periods may not provide an adequate baseline for comparison. Therefore, the 8-hour fasting requirement strikes a balance between obtaining reliable results and ensuring patient comfort and safety.
In conclusion, for patient compliance with GTT testing, it is essential to recommend a fasting period of at least 8 hours. This practice aligns with the standard protocols for GTT, facilitating accurate assessment of glucose metabolism and ensuring the reliability of the test results.
Therefore option c is the correct option.
