A nurse is evaluating preoperative teaching with a client who is to undergo surgery with general anesthesia. Which of the following statements by the client indicates an understanding of the teaching?

A. "I can leave my contact lenses in place during surgery.": Contact lenses must be removed before general anesthesia because they can cause corneal irritation or injury. Additionally, dry eyes during anesthesia increase the risk of corneal damage if lenses are left in place. B. "I will pull my hair back with a hair clip before applying the surgical cap.": Hair clips and pins are not permitted in the operating room because they may pose a risk of injury, interfere with surgical positioning, or be a source of contamination under the cap. C. "I should remove nail polish from my fingers before surgery.": Removing nail polish is essential because it allows accurate monitoring of oxygen saturation with a pulse oximeter. Nail polish can block or distort light transmission, leading to inaccurate readings. D. "I can keep my eye makeup on during surgery.": Eye makeup should not be worn because particles can enter the eye during anesthesia and cause irritation or infection. Additionally, makeup can interfere with the sterile environment of the operating room.
