pattern

needle holder
Q: the surgeon is ready to start suturing a patient. The circulating nurse takes the
exposed suture from the cassette and pulls it straight up, exposing about 6 inches of
suture and being careful not to let the suture touch the inside of the cassette. The sterile
assistant grasps the suture below the level that was initially exposed, and using a sterile
operating scissors, cuts the suture close to the hand, between her hand and the
circulating nurse's hand. The tech then hands the suture material to the surgeon. What
should be done differently next time? - Answer- After the xposed suture is cut away, the
