A 0900 the nurse begins the care of a patient who has just been transferred from the post anesthesia care unit. The patient has a new liter of D5\0.9 % NS infusing at 125 ml\per hour. The client has an indwelling urinary catheter with continuous bladder irrigation of NS infusing at 75 ml per hour, to keep the catheter free of clots. At 1500 the nurse empties 1575 ml from the urinary catheter. Consider the patient's I & O starting at 0900 and ending at 1500 and calculate the number of positive or negative mL.
