MRS Tom. is a 48-year-old female two days post-operative abdominal surgery. She has a foley to gravity drainage. While assessing J.D.'s vital signs at 12 noon, you note that there is no urine in the tubing and there is only a little in the bag. The patient tells you "I am in pain and I feel like I need to urinate."
