Virgina Medical Student Saves Life During Practice Exam (VIDEO)

Medical student Ryan Jones unexpectedly became a hero during what he thought was a routine practice exam at the University of Virginia.

Jones was participating in a program in which students diagnose actors who are faking symptoms of certain ailments. Jones's mock patient, Jim Malloy, was pretending to have an aneurysm when Jones realized that Malloy was actually suffering from an abdominal aortic aneurysm.

At first, Jones wasn't sure if Malloy's symptoms were simply an elaborate part of the program. But a supervising doctor confirmed Jones's suspicions.

"He thought I might have been a ringer that was planted in there to test him, but it wasn't, and I had no symptoms. So he thought I was a plant with the real situation," Malloy said to CBS News.

“He had the courage to speak up which is wonderful. [He] saved my life."

Jones said that he plans to become a radiation oncologist once he finishes medical school.
