There is always a question of people always ask me, from the day when I went to interview examinations at school nurse internship on ward (ward) or even myself, I was once asked this question to myself.. I remember that when the auditor interviewed answered, Because it is a career for nurses, easy-to-use good income is used in both the knowledge and the ability to perform and in daily life and it is also a career, and then it is good (this mother had told him).
