This may be a dumb question but. I have a home health pt with bad LE circulation. Has had several open areas in the past. Today has a 2cmx1cm open area. Looks like a skin tear without the flap but did have some white exudite in the center. I applied adaptic, telfa and wrapped? PCP agreed but not sure if this is the right way to go? How often should I change this or should I send him to see PCP or WCC? Has had it for 1 day per patient. Also wears TEDS.
