A patient is scheduled for abdominal surgery tomorrow. While gathering preoperative data, the nurse learns that the patient takes the following medications daily: an anticoagulant, a multivitamin, and vitamin E.
 
  The patient reports that he stopped taking the anticoagulant 4 days ago as instructed by the surgeon. He has continued to take the multivitamin and vitamin E. Based on the information given, the nurse notifies the surgeon because she:
  a. Needs an order to restart the anticoagulant
  b. Is concerned about continued use of the multivitamin
  c. Is concerned about the vitamin E
  d. Has canceled the surgery so more lab tests can be done.
