Which of the following is an expected finding in a client with diabetes insipidus?

In diabetes insipidus, a key characteristic is the inability of the kidneys to concentrate urine due to insufficient levels of antidiuretic hormone (ADH), also known as vasopressin. This leads to excessive loss of water through the urine, resulting in increased urination, a condition referred to as polyuria.

Individuals with diabetes insipidus frequently experience significant amounts of dilute urine output, which can significantly exceed normal urine volume. As a direct result of this excessive urination, there is a consequent increase in thirst, as the body attempts to compensate for the fluid loss. Thus, increased urination is indeed an expected finding in clients with diabetes insipidus, making that choice correct.

In contrast, decreased urine output, decreased thirst, and no impact on fluid balance are not consistent with the pathophysiology of diabetes insipidus. These findings would instead suggest an alternate diagnosis or condition.
