When Evaluating the Outcomes of Preoperative Teaching with a Patient

When evaluating the outcomes of preoperative teaching with a patient scheduled for a coronary artery bypass graft (CABG) using the internal mammary artery, the nurse determines that additional teaching is needed when the patient says,

A) "I will have incisions in my leg where they will remove the vein."
B) "They will circulate my blood with a machine during the surgery."
C) "I will need to take an aspirin a day after the surgery to keep the graft open."
D) "They will use an artery near my heart to bypass the area that is obstructed."
