The nurse is caring for a client immediately following the insertion of a permanent pacemaker. Which intervention should be included in the plan of care?

A. Teaching dressing changes is important but usually done later, not immediately post-insertion. B. Monitoring urine output is standard but not a priority specific to pacemaker insertion. C. Arranging feeding is not specifically related to pacemaker care. D.
