Question

9:18 PM a dcccd.blackboard.com O AT&T; 24% Jamie Richards is a 20 year old junior in college. She is majoring in biology and hopes someday to be a pediatrician Beginning about a month ago, Jamie noticed that she was waking up once, sometimes twice a night, by the need to go to the bathroom. More recently, she has noticed that she needs to go to the bathroom during her school day much more frequently than before, sometimes as often as once every hour At first, Jamie thought that her increased frequency of urination was due to all the coffee she drank, but when she reduced her coffee consumption to one cup in the morning, she still needed to go to the bathroom just as often. In addition, Jamie was buying bottled water by the case, and she found herself never without a beverage in her hand or nearby. She also noticed that her urine seemed pale and colorless When Jamie told her mother or her problem, her mother became very concerned and arranged for Jamie to see the family physician. Her physician found no abnormalities on physical examination. However, a blood chemistry profile revealed the following Plasma Plasma osmolality 308 mOsm/kg sodium level 149 mEq/kg Fasting plasma glucose 85 mg/dl Urine osmolality 200 mOsm/kg Urine glucose: negative

Explanation / Answer

6. levels in the first two hours indicate diabetes. A1C test is a test for blood glucose levels by measuring the percentage of glycated haemoglobin. A A1C level below 5.7 is considered normal. No Jamie doesnt have the disease becasue after first two hours her levels of glucose fell below normal and her initial glucose level was 80, which means the normal physiological processes in her body (insulin pathway) are working appropriately and thus she doesnt have the disease. Yess she has diabetes insipidus.
