What is the most appropriate response by a nurse when a client experiences heavy urine output after catheterization?

The most appropriate response when a client experiences heavy urine output after catheterization is to stop draining the bladder. This is because an excessive amount of urine output, especially following catheterization, could indicate that the bladder is functioning properly and releasing urine effectively. Continuing to drain the bladder can lead to unnecessary complications, such as overdistension or injury to the bladder.

Monitoring urine output is essential, as it can provide important insights into the client's fluid status and kidney function. If the heavy urine output persists or is accompanied by other concerning symptoms, further assessment or intervention may be warranted. However, in the immediate setting of catheterization, halting further drainage allows for proper evaluation of the situation. It is also important to consider that hydration status and factors influencing diuresis should be assessed before taking any action beyond stopping the drainage.
