Final answer:
The nursing intervention focused on promoting graft 'take' after an autograft is to leave the dressing intact for 3 to 5 days.
Step-by-step explanation:
The nursing intervention focused on promoting graft 'take' after an autograft is applied to the right lower extremity is to leave the dressing intact for 3 to 5 days.
By keeping the dressing intact, it provides a protective barrier that helps prevent infection and disturbance to the graft site, allowing for the initial graft adherence and formation of new blood vessels.
Removing the dressing too early can increase the risk of graft failure and complications.
