Which finding indicates that a client's hydration status has not changed?

A urine output of 1225 mL in 4 hours is consistent with expected hydration levels, indicating that the client is maintaining a normal hydration status. This volume suggests that the kidneys are effectively filtering blood and producing urine, reflecting a balanced intake and output of fluids.

In a healthy individual, normal urine output is approximately 800 to 2000 mL per day, depending on fluid intake and other factors such as body temperature and physical activity. A urine output of 1225 mL in just 4 hours translates to about 306 mL per hour, which is within the normal physiological range, suggesting adequate hydration.

Other findings would tend to indicate potential changes in hydration status. For example, significantly increased urine output might suggest overhydration or diuresis, decreased heart rate could be indicative of dehydration or other physiological changes, and weight loss is often associated with fluid loss, which would signify dehydration. Thus, the urine output of 1225 mL in 4 hours reliably indicates stable hydration status.
