A client is voiding frequent small amounts 24-hours following the removal of an indwelling catheter, and a post-voided residual volume assessment is prescribed. Which explanation should the practical nurse (PN) provide to the client about why the procedure is necessary?

The catheterization is part of the prescribed bladder retraining program.

The catheterized volume determines the need to re-insert the indwelling catheter.

The catheterization will stimulate the bladder to empty more completely.

The catheterization procedure is an exercise in stimulus-response conditioning.
