The patient is a 28-year-old female medical student who is referred to the Office of Student Affairs due to receiving an incomplete on her surgery clerkship. Upon questioning, she admits to "sneaking out" of the operating room in order to avoid participating in surgeries. When confronted with her unprofessional behavior and expectations of the rotation, she claims to have significant anxiety revolving around the operating room. She states, "It's not that I mind the surgery itself, just the blood." She proceeds to reveal numerous instances of feeling dizzy, lightheaded, and even fainting when seeing blood. As a result, she has been unable to donate blood while in college or medical school and has, thus far, been able to "work around" drawing blood in other clerkships.
