A Patient Who Has Just Returned from a Transurethral Resection

A patient who has just returned from a transurethral resection of the prostate (TURP) asks the nurse why he needs a urinary catheter. What is the correct explanation?

A) "We can take the catheter out when you are able to urinate on your own. I'll ask the physician if we can remove it later today."
B) "The catheter is being used to irrigate your bladder with antibiotics. It is important to continue this until you can take antibiotics orally."
C) "The catheter keeps your bladder empty to reduce risk for infection. It is important to leave it in for at least 72 hours."
D) "The catheter is keeping pressure on the area to prevent bleeding. We will remove it when the risk for bleeding has passed."
