Number 3 is correct.
Rationale: The priority after this procedure is monitoring the client for excessive bleeding. The nurse should observe the dressing for 24 hours for signs of bleeding or infection. It is not necessary to keep the client NPO after this procedure. Contact sports should be avoided for 48 hours. No further site care is required other than observing the dressing for 24 hours, unless signs of infection are noted.
