Licensed practical nurses (LPNs) and vocational nurses (LVNs) provide basic medical care, such as checking a patient's blood pressure. Duties of LPNs and LVNs vary, depending on their work setting and the state in which they work. For example, they may reinforce teaching done by registered nurses regarding how to help care for newborn infants, attend to the needs of inpatients, or collect laboratory samples for testing. Nurses must often be on their feet for much of the day. They are vulnerable to back injuries, because they may have to lift patients who have trouble moving in bed, standing, or walking.
LPNs and LVNs may be limited to doing certain tasks, such as feeding patients who cannot care for themselves, depending on the state where they work. For example, in some states, LPNs with proper training can give medication or start intravenous (IV) drips, but in other states LPNs cannot perform these tasks. State regulations also govern the extent to which LPNs and LVNs must be directly supervised. For example, an LPN may provide certain forms of care only with instructions from a registered nurse.
LPNs and LVNs must complete an accredited nurse training program. These programs award a certificate or diploma and typically take about 1 year to complete. They are commonly found in technical schools and community colleges, although some nursing programs may be available directly through hospitals. Practical nursing programs combine classroom learning in subjects such as nursing, anatomy, human physiology, biology, and pharmacology. Programs also include supervised clinical experience and hospital rotations.
After completing a state-approved educational program, prospective nurses can take the National Council Licensure Examination (NCLEX-PN). In all states, they must pass the exam to get a license and work as an LPN or LVN. For more information on the NCLEX-PN examination and a list of state boards of nursing, visit the National Council of State Boards of Nursing. LPNs and LVNs may choose to become certified in specialty areas such as gerontology and intravenous (IV) therapy.
Basic Life Support (BLS) certification demonstrates proficiency in cardiopulmonary resuscitation (CPR) techniques and basic life-saving skills. This certification is usually issued by organizations such as the American Heart Association or the American Red Cross. BLS certification ensures that LVNs/LPNs are prepared to respond effectively to medical emergencies and provide immediate assistance to patients in critical situations.
Some LVNs/LPNs pursue additional training and certification in intravenous (IV) therapy to administer medications, fluids, and blood products intravenously to patients. IV therapy certification programs provide specialized education and hands-on training in venipuncture, IV insertion techniques, and IV medication administration.

Lung anatomy and physiology of gas exchange in the lung alveoli during respiration. This lecture details the anatomy of the lungs and how gas exchange in the lungs takes place between carbon dioxide and oxygen. The lung is made up of many components that participant in gas exchange.
An LPN/LVN has diverse responsibilities in providing compassionate, competent, and holistic nursing care to patients across various healthcare settings, including hospitals, long-term care facilities, clinics, and home health agencies. They play a vital role in patient education, providing information and guidance on managing chronic conditions, adhering to treatment plans, and promoting healthy lifestyles. They educate patients and their families on medication use, dietary guidelines, home care procedures, and self-care techniques.
