Most of the time do a focused PE. I think I threw in CV/Chest occasionally when I had time. It's really a timing thing you need to get down. History in this much time, PE in this much time, counseling in this much time. If you have to choose between PE and counseling, choose counseling. You can always do the PE after counseling if you end up with a minute or so-you'll still get the points.
Make sure to be really personable and nice, as if each patient you're seeing is your favorite patient.
