Registered nurses are employed in a wide variety of professional settings and often specialize in a field of practice. They may be responsible for supervising care delivered by other healthcare workers, including student nurses, licensed practical nurses, unlicensed assistive personnel, and less-experienced RNs.
Registered nurses must usually meet a minimum practice hours requirement and undertake continuing education to maintain their license. Furthermore, there is often a requirement that an RN remains free from serious criminal convictions.
