The number of men in the U.S. with the job of registered nurse has nearly tripled since the early 2000s. Many come to the field after working in the military or in jobs, such as paramedics or firefighters, that exposed them to the work of nurses. "What I hear a lot from female students is, 'I've always wanted to be a nurse, I like helping people,' where the men tend to look more at job security and job stability," says Jason Mott, president of the American Association for Men in Nursing.
