Write answer in between .Q:A 24-year-old woman comes to the physician because of a 2-month history of increased urination. She has also had dry mouth and excessive thirst despite drinking several gallons of water daily. She has a history of obsessive-compulsive disorder treated with citalopram. She drinks 12 cans of beer daily. Physical examination shows no abnormalities. Serum studies show a Na concentration of 130 mEqL, a glucose concentration of 185 mgdL, and an osmolality of 265 mOsmolkg. Urine osmolality is 230 mOsmolkg. The patient is asked to stop drinking water for 3 hours. Following water restriction, repeated laboratory studies show a serum osmolality of 280 mOsmolkg and a urine osmolality of 650 mOsmolkg. Which of the following is the most likely diagnosis?? A: Primary hyperparathyroidism, B: Syndrome of inappropriate ADH secretion, C: Nephrogenic diabetes insipidus, D: Primary polydipsia, E: Beer potomania,  <response>: This is a clinical case of a 24-year-old woman with symptoms of polyuria, polydipsia, and dry mouth. The key findings are:- Increased urination and thirst despite drinking gallons of water daily - suggests diabetes insipidus- Serum Na 130 mEqL - low, indicates dilutional hyponatremia - Serum glucose 185 mgdL - elevated, indicates hyperglycemia- Serum osmolality 265 mOsmkg - low, indicates dilute serum - Urine osmolality 230 mOsmkg - low, indicates dilute urine- After water restriction - serum osmolality increased to 280 mOsmkg and urine osmolality increased to 650 mOsmkg. This indicates the kidneys ability to concentrate urine when challenged with water restriction.Based on the low serumurine osmolality that concentrates with water restriction, the most likely diagnosis is primary polydipsia. The other choices can be ruled out based on the clinical findings.D: Primary polydipsia
