10. The graph shows data for a 5-hour glucose tolerance test for four patients. Symptoms of a patient with diabetes during a 5-hour glucose tolerance test include a high blood-glucose level that increases quickly and then decreases only minimally over the 5-hour period. Which patient displays symptoms of diabetes?
Answer: C
Patient 4 displays symptoms of diabetes during the glucose tolerance test.
During the 5-hour glucose tolerance test, patient 4 shows a high blood-glucose level that increases rapidly and decreases only minimally, indicating symptoms consistent with diabetes.
A) patient 2
Patient 2 does not exhibit the key symptoms of diabetes as defined by the glucose tolerance test. Their blood-glucose levels may either remain stable or decrease significantly over the testing period, which does not align with the expected pattern for a diabetic response.
B) patient 1
Patient 1's results are not indicative of diabetes, as they likely show a normal response to glucose, where blood-glucose levels peak and then drop significantly. This pattern is typical for non-diabetic patients, contrasting with the symptoms described for diabetes.
C) patient 4
Patient 4's glucose levels increase sharply and then decrease only slightly over the 5-hour period, which is characteristic of diabetes. This pattern reflects the body's inadequate response to insulin, leading to prolonged elevated glucose levels.
D) patient 3
Patient 3 does not demonstrate the symptoms of diabetes, as their glucose levels may either normalize or decline appropriately following the initial spike. This response indicates a healthy glucose metabolism, contrary to what is observed in diabetic patients.
Conclusion
Patient 4 is definitively the one who displays symptoms of diabetes, as their glucose response aligns with the typical profile of a diabetic individual. In contrast, the other patients show normal or healthier glucose patterns, which rule them out as candidates for diabetes based on the test results.
