After a transurethral resection of the prostate (TURP), a patient is discharged from the hospital with an indwelling urinary catheter. What is the most important instruction for the nurse to include in the discharge teaching plan?

Choice A rationale Similar to, while spicy foods can irritate the urinary tract, they do not have a direct impact on the care and management of an indwelling urinary catheter after a TURP3. Choice B rationale As in, drinking 3 liters of water each day is important as it helps flush the bladder and reduce the risk of urinary tract infections, which are a common complication after a TURP3. Choice C rationale As in, clamping the catheter is not typically recommended as it can lead to urinary retention and increase the risk of urinary tract infections. Choice D rationale As in, avoiding driving for 2 weeks is a general recommendation after any major surgery to allow the body time to heal, but it does not directly relate to the care of an indwelling urinary catheter.
