A 75-year-old man with a long history of diabetes mellitus is found unresponsive inhis apartment. He appears dehydrated. His serum glucose concentration is 860 mg/dL. A urine dipstick shows 4+ glucose and no ketones. Which of the following circulating hormones is the most likely cause of the absence of urinary ketones despite the increased serum glucose concentration?a. ADH (vasopressin)b.GlucagonC. Insulin d. Pancreatic polypeptide e. Somatostatin

A patient suffering from a tumor in the hypothalamus produces excessive amounts of ADH, acondition called syndrome of inappropriate ADH (SIADH) production. For this patient, the excessive ADH production is chronic and has persisted for many months. A student nurse keeps a fluid intake-output record on the patient. She is surprised to find that fluid intake and urinary output are normal. Using a flowchart and your knowledge on feedback mechanisms, show why the urinary output isnormal in this patient.
