Experiment Results Predict Question: Predict Question: To measure the amount of plasma glucose in a patient sample Your answer : b. the optical density of the sample will be measured and the glucose concentration will be extrapolated from the glucose standard curve. Stop & Think Questions: Why does the color in the tubes vary? You correctly answered: c. The tubes contain different amounts of glucose. Post-lab Quiz Results You scored 100% by answering 6 out of 6 questions correctly. 1. A male patient has had successive fasting plasma glucose readings of 115, 110, and 122 mg/dl. The healthcare provider will inform him that You correctly answered: c. he appears to have impairment or borderline impairment of insulin-mediated glucose uptake by his cells. 2. To obtain an accurate spectrophotometric measurement of the glucose concentration in the sample You correctly answered: d. heparin is added to prevent blood clots. 3. In the spectrophotometric assay used in this experiment, the __________ as the glucose concentration in the sample increases. You correctly answered: b. optical density increases 4. A female patient has had successive fasting plasma glucose readings of 130, 140, and 128 mg/dl. The healthcare provider will inform her that You correctly answered: a. she has developed diabetes. 5. To maintain plasma glucose homeostasis You correctly answered: d. insulin-mediated transport of glucose into cells acts as negative feedback when plasma glucose levels rise. 6. A laboratory technician withdraws a blood sample from a vein in your upper arm knowing that You correctly answered: b. the plasma glucose concentration will be the same in both the arm vein and the index finger. Review Sheet Results 1. What is a glucose standard curve, and why did you need to obtain one for this experiment? Did you correctly predict how you would measure the amount of plasma glucose in a patient sample using the glucose standard curve? Your answer: A glucose standard curve is a method for identifying blood glucose levels which was in keeping with my prediction. 2. Which patient(s) had glucose reading(s) in the diabetic range? Can you say with certainty whether each of these patients has type 1 or type 2 diabetes? Why or why not? Your answer: Patients one and five were in the diabetic range. I can assess with certainty the patients conditions because Type1 is if the pancreas is not producing sufficient insulin and Type 2 is if the cells in the body are unresponsive to circulating insulin. 3. Describe the diagnosis for patient 3, who was also pregnant at the time of this assay. Your answer: She likely has gestational diabetes. 4. Which patient(s) had normal glucose reading(s)? Your answer: Patient 1. 5. What are some lifestyle choices these patients with normal plasma glucose readings might recommend to the borderline impaired patients? Your answer: Follow a controlled diet to keep the glucose readings in at normal levels and exercise regularly.
