One of your coworkers recently told you that he is HIV-positive. He shared information with you that his partner is very ill with AIDS. You observe, while this man is talking to you, that he has a small draining, open lesion on his left arm. You are concerned about his health and caution him to be careful. The next day you see that he is on a list of CPR instructors who will be testing employees. Your facility still uses an older version of CPR in which there is mouth breathing performed on the "Annie."
