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?

A. The post-voided residual volume assessment is not part of a bladder retraining program but is a diagnostic tool used to assess bladder function after catheter removal. This explanation misrepresents the purpose of the procedure. B. The post-voided residual volume assessment measures how much urine remains in the bladder after the client has voided. This measurement helps determine if the bladder is emptying properly and whether there is a need for catheter re-insertion. C. Post-voided residual volume assessment does not stimulate the bladder to empty more completely; instead, it measures the amount of urine left in the bladder. The procedure is diagnostic rather than therapeutic. D. The post-voided residual volume assessment is a diagnostic procedure, not an exercise in conditioning. This explanation does not accurately describe the clinical purpose of the assessment.
