A patient who takes daily doses of aspirin is scheduled for surgery next week. The nurse should advise the patient to:
a. continue to use aspirin as scheduled.
b. reduce the aspirin dosage by half until af-ter surgery.
c. stop using aspirin immediately.
d. stop using aspirin 3 days before surgery.
C
Aspirin must be withdrawn at least 1 week before surgery. Aspirin cannot be continued as sche-duled, because the risk for bleeding is too great. An interval of 3 days is not long enough for the bleeding effects of aspirin to be reversed. Cutting the dose in half would not reduce the effects of bleeding associated with aspirin use.
