Question

Quizplus · Accepted Answer

SIADH is characterized by excessive secretion of antidiuretic hormone (ADH), which leads to retention of water in the body, resulting in hyponatremia and decreased serum osmolarity. Urine sodium levels are typically elevated in SIADH due to the increased reabsorption of water in the kidneys. Urine calcium levels are not typically affected by SIADH.
