Final answer:
A three-way catheter would be used to monitor urinary output during Ms. Tovar's Left Nephrectomy.
Step-by-step explanation:
The foley catheter that would be used to monitor urinary output during Ms. Tovar's Left Nephrectomy would be a three-way catheter. A three-way catheter has an additional lumen, or channel, that allows for continuous irrigation of the bladder. This is useful in procedures that may cause bleeding or require the bladder to be kept empty. The continuous irrigation helps to prevent blood clots from forming and obstructing the catheter.
