High school students can explore an interest in this career by reading books or by checking out Web sites devoted to the nursing field. You should also take advantage of any information available in your school career center. An excellent way to learn more about this career firsthand is to speak with the school nurse or local public health nurse. Visits to a local hospital can give you a feel for the work environment. Volunteer work at a hospital, community health center, or even the local Red Cross chapter can provide valuable experience. Some high schools offer membership in Future Nurses organizations.

Licensed practical nurses work under the supervision of a registered nurse, or a physician. They are responsible for many general duties of nursing such as administering prescribed drugs and medical treatments to patients, taking patients vital signs (temperature, blood pressure, pulse, respiration), dressing wounds, assisting in the preparation of medical examination and surgery, giving injections and enemas, and performing routine laboratory tests. LPNs help with therapeutic and rehabilitation sessions; they may also participate in the planning, practice, and evaluation of a patients nursing care.

A primary duty of an LPN is to ensure that patients are clean and comfortable, and that their needs, both physical and emotional, are met. They sometimes assist patients with daily hygiene such as bathing, brushing teeth, and dressing. Many times they provide emotional comfort by simply talking with the patient.

LPNs working in nursing homes have duties similar to those employed by hospitals. They provide bedside care, administer medications, develop care plans, and supervise nurse assistants. Those working in doctors offices and clinics are sometimes required to perform clerical duties such as keeping records, maintaining files and paperwork, as well as answering phones and tending the appointment book. Home health LPNs, in addition to their nursing duties, may sometimes prepare and serve meals to their patients. They also teach family members how to provide basic care for their loved ones when medical professionals are unavailable.
