Licensed practical nurses (LPNs) care for people who are sick, injured, or have disabilities.

Licensed practical nurses work under the direction of a doctor or registered nurse (RN).

Most LPNs provide basic bedside care to patients. They take vital signs such as temperature, blood pressure, pulse, and respiration. They discuss health care with patients and listen to their concerns. They also help maintain patient records.

LPNs observe patients and report any negative reactions to treatments or medications. They collect blood and other samples from patients for testing. In some work settings, they perform routine lab tests. They prepare patients for more complex tests and exams, explain how procedures work, and answer questions.

LPNs answer patient calls. They monitor patients and change bandages and insert catheters. They treat patients for bedsores, apply dressings, and assist with meals. They also apply hot water bottles and ice packs.

In nursing homes and other care facilities licensed nurses help patients bathe, brush teeth, and get dressed. They may help evaluate the needs of residents and assist others in developing care plans.

In private homes, LPNs may prepare meals. They may also teach simple nursing tasks to family members.

In doctors' offices and clinics, LPNs often make appointments, keep records, and perform other clerical duties. They also set up exam or treatment rooms.

In some states, licensed practical nurses may give medications to patients. They may also start intravenous (IV) fluids.

In all settings, experienced LPNs supervise nursing assistants and aides.
