Answer: B. Three-way Foley
Step-by-step explanation:
In the case of this postoperative, the catheter that is used is a Three-way Foley.
After the surgery, the physician needs to know who much blood and how much urine is going out by the urethra; and how much of those are produced after the surgery. It helps to know if the tissue is healing, I mean, if there is less blood every day, then the outcome of the surgery could be better.
The Three-way Foley also has a bag at the end that allows to measure the quantity of the urine that is expected to produce every day.
The three-way Foley is also a catheter with a balloon that inflates inside the bladder in order to keep the catheter in position, until the physician tell the patient, it is time to pull out.
