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