Final answer:
Vasopressin treatment in diabetes insipidus aims to reduce urine output and enhance water conservation in the body by acting on the kidneys to increase water reabsorption.
Step-by-step explanation:
Vasopressin (also called antidiuretic hormone or ADH) is administered in the treatment of diabetes insipidus (DI), primarily to achieve a reduction in urine output and improve water retention. When the body lacks sufficient levels of ADH, a condition characteristic of DI, it cannot retain water effectively, leading to excessive urine production and dehydration. The therapeutic effect of vasopressin in such patients is an expectant decrease in urine output (C) due to its action on the kidneys, promoting water reabsorption.
Vasopressin (also called antidiuretic hormone (ADH)) helps to maintain homeostasis in body water. It stimulates the kidneys to conserve water by producing more concentrated urine. Specifically, vasopressin targets ducts in the kidneys and makes them more permeable to water. This allows more water to be resorbed by the body rather than excreted in the urine.
