What is the purpose of a catheter during surgery?

The purpose of a catheter during surgery often centers around urinary management, and option B describes one of the primary uses during surgical procedures: decompressing the bladder. When a patient undergoes surgery, especially in lower abdominal or pelvic areas, it is crucial to ensure that the bladder is empty. This helps to prevent injury to the bladder during surgery and provides a clearer surgical field for the surgeon to operate.

Additionally, decompressing the bladder reduces discomfort for the patient and minimizes the risk of complications related to a full bladder, such as bladder rupture or urinary retention. The catheter is typically inserted prior to the procedure and may remain in place for the duration of the surgery.

While catheters can also be used for other purposes, such as administering medications, draining wound fluid, or collecting urine specimens, those uses are more situational and not the primary focus during surgery, especially concerning bladder management. Thus, the main purpose of a catheter during surgical procedures is effectively described by the need to decompress the bladder.
