My mother had a femoral bypass. How can I take care of her?

TLC. Make sure the wounds are dry. Painting the incisions with betadine twice a day can help prevent infections. Be around to assist when she wants to get up and walk- walking is good thing. If she has leg swelling, a low pressure compression sock (below the knee) can help.
Activity. Make sure that she does not smoke, eats a healthy diet and stays active.
