Read the following case study and answer all questions listed:

One of your co-workers 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.

Whom should you notify about your concerns?

Should you approach your co-worker and tell him about your concerns?
