Which of the following outcomes would indicate successful treatment of diabetes insipidus?
Correct Answer: A
Rationale: Successful treatment of diabetes insipidus is indicated when the patient's excessive urination (polyuria) and thirst (polydipsia) are controlled. One of the primary goals of treatment is to achieve fluid balance by reducing urine output and, consequently, decreasing the excessive thirst. When the fluid intake is less than 2,500mL, it suggests that the patient's excessive thirst has decreased, indicating successful management of the condition. Monitoring and managing fluid intake are crucial in the treatment of diabetes insipidus to prevent dehydration and electrolyte imbalances. A lower fluid intake is a positive indicator that the treatment is effectively addressing the increased urine output characteristic of diabetes insipidus.
