Licensed Practical Nurse (LPN)
What is an LPN?
A Licensed Practical Nurse (LPN) is a healthcare professional who has completed a state-approved practical nursing program and passed the NCLEX-PN licensure examination (in the U.S.). LPNs provide direct patient care under the supervision of registered nurses (RNs) or physicians, depending on state regulations and facility policies. Their responsibilities include monitoring patients, administering medications within their scope, performing wound care, collecting specimens, and assisting with activities of daily living. LPNs are vital members of the healthcare team, particularly in long-term care, rehabilitation, and outpatient settings.
LPN responsibilities vary by jurisdiction and employer. Always practice within the legal scope defined by your licensing board.

LPN Scope of Practice
The scope of practice for LPNs defines the procedures, actions, and processes that a licensed practical nurse is permitted to perform under the law. Scope is determined by:
- Jurisdictional regulations – State nursing boards define legal scope.
- Supervision requirements – Some tasks require RN or physician oversight.
- Employer policies – Facilities may restrict or expand certain duties.
- Patient complexity – LPNs typically care for stable, predictable patients.
- Education and competency – Additional training may be required for some skills.
LPN Education and Training
- Prerequisite education – High school diploma or equivalent; some programs require prerequisite courses.
- Practical nursing program – Completion of a state-approved LPN/LVN program.
- Classroom learning – Courses in anatomy, physiology, pharmacology, nursing fundamentals.
- Laboratory/simulation training – Practice skills in a controlled environment.
- Clinical rotations – Supervised hands-on experience in healthcare settings.
- Graduation – Award of a certificate or diploma in practical nursing.
- Licensure examination – Passing the NCLEX-PN (U.S.) or equivalent exam.
- State/provincial licensing – Application for licensure with the appropriate regulatory body.
- Continuing education – May be required for license renewal (varies by jurisdiction).
Program duration and specific requirements vary by state and country. Always verify with the relevant nursing board.
NCLEX-PN
NCLEX-PN stands for the National Council Licensure Examination for Practical Nurses. It is the standardized examination used in the United States to assess the competency of candidates seeking licensure as practical or vocational nurses. The exam evaluates entry-level nursing knowledge and is administered by the National Council of State Boards of Nursing (NCSBN).
- Passing the NCLEX-PN is required for licensure in most U.S. states.
- The exam covers areas such as safe and effective care environment, health promotion, and psychosocial integrity.
- Content is based on current nursing practice and changes periodically.
LPN vs RN
| Feature | LPN | RN |
|---|---|---|
| Full Name | Licensed Practical Nurse | Registered Nurse |
| Education | Practical nursing program (approx. 1 year) | ADN, BSN, or diploma program (2–4 years) |
| Licensure Exam | NCLEX-PN | NCLEX-RN |
| Scope | Depends on jurisdiction | Depends on jurisdiction |
| Patient Care | Provides nursing care within scope | Provides broader nursing responsibilities within scope |
| Assessment | Performs assessments as permitted by jurisdiction | Performs comprehensive nursing assessment |
| Care Planning | Participates according to role/scope | Develops/manages nursing care plans as permitted |
| Supervision | May work under required supervision | May supervise/delegate according to law and policy |
Exact responsibilities vary by jurisdiction, employer, and clinical setting.
LPN vs LVN
LPN = Licensed Practical Nurse
LVN = Licensed Vocational Nurse
The terms are used differently in the United States depending on the state, while referring to comparable practical/vocational nursing roles. In most states, the title LPN is used. In Texas and California, the title LVN is used. The scope of practice, education, and licensure examination (NCLEX-PN) are essentially equivalent. Always verify the specific regulations of your state nursing board.
Common LPN Work Settings
Hospitals
Medical-surgical, maternity, and specialty units.
Long-Term Care
Nursing homes and skilled nursing facilities.
Rehabilitation Centers
Post-acute and physical rehabilitation.
Clinics
Outpatient and specialty clinics.
Physician Offices
Primary care and specialty practices.
Home Health
Visiting patients in their homes.

Specific skills permitted vary by jurisdiction, employer policy, and individual competency.
LPN and Laboratory Testing
LPNs interact with laboratory testing through various activities, including:
- Preparing patients – Explaining procedures, positioning, and ensuring proper preparation.
- Collecting specimens – Blood, urine, sputum, and other specimens when permitted.
- Labeling and handling – Proper labeling and handling according to policy.
- Monitoring patients – Before and after certain procedures.
- Recognizing abnormal results – Identifying results that require communication/escalation.
- Documenting – Recording laboratory-related care in medical records.
- Specimen transport – Supporting transport according to facility protocols.
LPNs do not replace medical laboratory professionals. Instead, nursing and laboratory teams work together to ensure appropriate specimen collection, handling, communication, and patient care. Always follow facility policies and scope of practice guidelines.
Common Laboratory Tests LPNs May Encounter
| Test | Common Clinical Purpose |
|---|---|
| CBC | Evaluates blood cell counts |
| BMP | Evaluates electrolytes, glucose, and kidney-related markers |
| CMP | Provides broader metabolic and liver-related information |
| PT/INR | Evaluates aspects of blood clotting |
| aPTT | Evaluates part of the coagulation pathway |
| HbA1c | Reflects average blood glucose over approximately 2–3 months |
| Urinalysis | Evaluates urine characteristics and abnormalities |
| Blood glucose | Measures current blood glucose |
| Cultures | Helps identify infectious organisms |
| Lipid panel | Evaluates cholesterol and triglycerides |
Interpretation of laboratory results and clinical decisions depend on the patient’s overall condition and the responsibilities of the appropriate licensed professionals.
LPN Documentation
Accurate and timely documentation is essential for patient safety, continuity of care, and legal protection. LPNs document:
- Vital signs and patient observations
- Medication administration records
- Specimen collection and handling
- Changes in patient condition
- Communications with the healthcare team
- Treatments and patient responses
Documentation should be objective, complete, and compliant with facility policies and regulatory standards.
