The Nurse Has Implemented a Bladder Retraining Program for an Older

The nurse has implemented a bladder retraining program for an older adult patient. The nurse places the patient on a timed voiding schedule and performs an ultrasonic bladder scan after each void. The nurse notes that the patient typically has approximately $50 \mathrm{~mL}$ of urine remaining in her bladder after voiding. What would be the nurses best response to this finding?

A) Perform a straight catheterization on this patient.
B) Avoid further interventions at this time, as this is an acceptable finding.
C) Place an indwelling urinary catheter.
D) Press on the patients bladder in an attempt to encourage complete emptying.
