Height: 5'7"       Weight: 198#        UBW: 220# The doctor ordered the administration of chemotherapy with 5-Fluorouracil (5-FU) and improvement of his nutritional condition before surgery (Whipple procedure).Other meds prescribed: Zofran, Duragesic, pancrealipase, regular insulin. Diet Order: NPO -How much body weight loss has ML experienced?
