Endocrine Case Histories - Case 25 A 28-year-old male complained of abrupt polydipsia and polyuria. Blood and urine analyses provided the following results: Fasting blood glucose 93 mg/dL Serum sodium 145 mEq/L Serum potassium 2.8 mEq/L Urine specific gravity <1.005 Urine osmolality <200 mOsm/L Urine volume 15 L/day Urine glucose 0 Water deprivation and hypertonic saline infusion do not cause a significant reduction in the polyuria and concentration of urine. Complete water-deprivation results in the following: Urine specific gravity 1.009...
A 80 year old patient is hospitalized for vomiting and diarrhea that developed 2 days prior to admission. The patients home medications include furosemide. Current vital signs are temperature 100.9, sinus tachycardia at127 bpm, blood pressure 100/57, respirations 24 per min, regular and non-labored. A Foley catheter is placed and returns with 110 mL of dark amber urine over the last 5 hours. Tenting of skin is noted when pinched over the sternum. Patient mucous membranes are dry with deep...
