- If the groin area was used as the insertion site, you will be instructed to lie in bed with your legs out straight.
- If the wrist or arm was used as the insertion site, you will not need to stay in bed.
- The insertion site will be monitored for signs of bleeding, swelling, or inflammation.
- Your vital signs will be monitored.
