Following gallbladder surgery, a patient has a T-tube with thick, dark green drainage. When the patient asks about the tube and the drainage, the best response by the nurse is

A) "The drainage is from your gallbladder, but it should be bright yellow rather than green."
B) "The drainage is old blood and fluid that accumulates at the surgical site. Its removal will promote healing."
C) "The tube you see has been placed in the bile duct, and the drainage is normal bile."
D) "The tube is draining secretions from the duodenum and small bowel, and this is normal drainage from this area."
