Jessie's initial blood test results show that her common electrolytes, blood pH, lactate, pyruvate, total ammonia, oxygen, and carbon dioxide levels are all within the normal ranges. Jessie has elevated levels of triacylglycerides and fatty acids and normal levels of cholesterol. However, there is no evidence of ketone body formation. You also test for common lipids, including fatty acids (FAs), triacylglycerides (TAGs), total cholesterol, and ketone bodies, using acetoacetate as a marker. Which statement best explains Jessie's test results ? Test Jessie's level Normal range 190–420 FAS 500 mg/dL mg/dL TAGS 175 mg/dL 40–150 mg/dL total 120-200 140 mg/dL cholesterol mg/dL ketone bodies undetectable 5–30 ug/mL O She has elevated levels of triacylglycerides and fatty acids, because she is obese. She has elevated levels of triacylglycerides and fatty acids, because she recently ate a large meal. She does not produce ketone bodies due to her athleticism. She does not produce ketone bodies because of her vegan diet. She does not produce ketone bodies due to a metabolic impairment. In addition to the previously performed blood tests, you also test Jessie's blood glucose concentration, which is 60 mg/dL (normal range: 70–110 mg/dL). Although the test indicates that Jessie is hypoglycemic, it is unclear whether this is due to an acute process or a chronic problem regulating her blood glucose level. How can you distinguish whether Jessie's abnormal blood glucose level is due to an acute process lasting hours or days or a chronic process lasting weeks or months? O Measure her body composition, including her body fat percentage. Measure her blood insulin level. Measure her glycated (glycosylated) hemoglobin level. Measure her fasting blood glucose level every day for two weeks. Measure her total hemoglobin level. The physician you are working with agrees with your idea to test Jessie's level of glycated hemoglobin, using hemoglobin Alc (HbA1c) as a marker, to determine whether Jessie has chronic hypoglycemia. The lab returns an abnormal result. What new information does the result of the glycated hemoglobin (HbA1c) test provide? Jessie is hyperglycemic right now. Jessie is hypoglycemic right now. Jessie has had higher than normal blood glucose levels over the past three months. Jessie has had lower than normal blood glucose levels over the past three months. Jessie's HbAlc = 3.2% (normal range: 4–6.5%)
