Licensed practical nurses ensure the well-being of patients. They monitor vital signs, provide nutrition, administer medications, change dressings and offer comfort. In a hospital, they may also be responsible for providing personal care before and after surgery and cleaning and sterilizing the operating room and its instruments. This is a rewarding and essential job that suits empathetic, discreet and vigilant people. A job as a licensed practical nurse requires being in excellent physical condition, good listening skills, initiative and good judgment.
