If a client has an output of 250 ml, how much water should a nurse administer based on the prescribed fluid replacement?

When determining the appropriate amount of fluid to administer based on a client's output, it’s essential to understand the principles of fluid replacement therapy. In this case, the output recorded is 250 ml, and the appropriate amount of fluid to replace would typically be calculated by considering factors such as maintaining a balance of intake and output, as well as the needs of the client based on their condition.

Administering 100 ml of water aligns with common clinical practice, where fluid replacement is guided by the necessity to compensate for losses and prevent dehydration. This amount serves as an effective way to ensure that the client remains adequately hydrated, especially if they are experiencing a loss of fluids.

The other amounts are less aligned with standard fluid replacement protocols. For instance, significantly lower volumes, such as 40 ml or 75 ml, may not sufficiently address the need created by a 250 ml output. In contrast, a higher volume like 200 ml could potentially lead to fluid overload, which can be risky for clients, especially for those with certain medical conditions such as heart failure or renal impairment. Therefore, choosing to administer 100 ml strikes a careful balance and promotes effective fluid management.
