Licensed Practical Nurse

LPNs, or Licensed Vocational Nurses (LVNs), as they are called in Texas and California, care for the sick, injured, convalescent, and disabled under the direction of physicians and registered nurses. They provide basic care, taking vital signs, temperature, blood pressure, and pulse, and assist with bathing patients, monitoring catheters, and applying dressings. Most LPN or LVN programs are about a yearlong and are offered by technical and vocational schools.
