A Nursing Practice Act (NPA) is a state law that defines what nurses can and cannot do, sets the requirements for getting and keeping a nursing license, and establishes the legal authority to discipline nurses who violate its standards. Every U.S. state and territory has its own NPA, and together with accompanying rules and regulations, these laws form the legal foundation for all nursing practice in that jurisdiction. The core purpose is straightforward: protecting the public from unsafe or incompetent nursing care.
What an NPA Actually Covers
An NPA is legislation passed by a state legislature. It typically addresses several key areas: who qualifies for a nursing license, what each type of nurse is legally permitted to do (known as scope of practice), how the state board of nursing operates, what counts as a violation, and what penalties the board can impose. Think of it as the rulebook that every nurse in a given state must follow to practice legally.
After the legislature passes the NPA, regulatory bodies (usually the state board of nursing) create more detailed rules and regulations that fill in the specifics. For example, the NPA might say nurses must complete continuing education to renew their licenses, while the board’s regulations spell out exactly how many hours and what topics qualify. Together, the law and its regulations guide and govern nursing practice on a day-to-day basis.
How Scope of Practice Differs by License Type
One of the most important things an NPA does is define scope of practice for each level of nursing. This determines the clinical tasks a nurse can legally perform, and it varies significantly between registered nurses (RNs), licensed practical nurses (LPNs), and advanced practice registered nurses (APRNs).
RNs function at an independent level. They are responsible for performing initial and comprehensive patient assessments, formulating nursing diagnoses, creating care plans, and evaluating whether interventions are working. They also direct LPN practice and delegate tasks to other licensed nurses and unlicensed assistive personnel.
LPNs function at a dependent level, meaning they work under RN supervision. An LPN can collect patient data and recognize changes in a patient’s condition, but it is outside their legal scope to perform a comprehensive initial assessment, interpret clinical data independently, or develop a nursing care plan on their own. They contribute to these processes in collaboration with an RN. LPNs can carry out nursing interventions, provide patient education, and report patient responses, but an RN or APRN cannot delegate tasks to an LPN that fall outside the LPN’s scope. Notably, while an LPN may hold an administrative role, they cannot legally direct or supervise the practice of a registered nurse.
APRNs, which include nurse practitioners, nurse midwives, nurse anesthetists, and clinical nurse specialists, have the broadest scope. Many state NPAs grant APRNs independent prescriptive authority, meaning they can prescribe medications without a physician’s oversight or a collaborative agreement. However, not every state has adopted this model, which creates significant variation in what APRNs can do depending on where they practice.
Why NPAs Vary From State to State
Because each state writes its own NPA, there is no single national standard for nursing practice. This means the rules governing supervision requirements, scope of practice, continuing education, and APRN autonomy can look quite different depending on where you are. A nurse practitioner practicing independently in one state might need a formal physician collaboration agreement just across the border.
Continuing education requirements are a clear example. Alabama requires 24 contact hours for license renewal. California requires 30 hours every two years. Arkansas accepts 15 contact hours, a current national certification, or a completed college credit course in nursing. Arizona requires no continuing education at all. Alaska temporarily reduced its renewal requirement from 30 hours to 15 hours for both RNs and LPNs.
The Nurse Licensure Compact (NLC) helps address some of this fragmentation by allowing nurses to hold a single multistate license. Currently, 43 jurisdictions have enacted the NLC, which means a nurse licensed in one compact state can practice in any other compact state without obtaining a separate license. Nurses in non-compact states still need to apply for individual licenses in each state where they want to work.
Grounds for Disciplinary Action
Every NPA includes provisions for what happens when a nurse violates the law. State boards of nursing have the authority to investigate complaints, hold hearings, and impose penalties ranging from fines and mandatory education to license suspension or permanent revocation.
The list of violations that can trigger disciplinary action is broad. Florida’s NPA, which is representative of many states, includes grounds such as:
- Substance-related issues: being unable to practice with reasonable skill and safety due to illness or the use of alcohol, drugs, or chemicals, or engaging in the possession, sale, or distribution of controlled substances for unauthorized purposes
- Patient exploitation: using undue influence on a patient for financial gain, or soliciting patients through fraud or intimidation
- Criminal convictions: being convicted of a forcible felony, theft, child abuse or neglect, domestic violence, or any crime that directly relates to the practice of nursing
- Unprofessional conduct: a broad category defined by board rule that covers behavior falling below accepted professional standards
- Record-keeping failures: failing to maintain legible medical records that document diagnoses, treatments, drugs prescribed, and referrals
- Action by another state: having a nursing license revoked, suspended, or denied by the licensing authority of another state or country
NPA vs. Standards of Care
The Nursing Practice Act and professional standards of care are related but distinct. The NPA is a statute, a law with legal force that defines minimum requirements for licensure and practice. Professional standards of care, published by organizations like the American Nurses Association, describe the expected level of competence for nursing practice and specialty areas. They outline professional boundaries, ethical expectations, and quality benchmarks.
Defining scope of practice is generally a two-step process. First, the state legislature passes the NPA. Then regulatory bodies create rules and regulations intended to protect the public. Professional standards layer on top of this legal framework by describing what competent nursing actually looks like in daily practice. In a malpractice case, both can come into play: the NPA establishes whether a nurse was practicing within their legal scope, while standards of care help determine whether they performed that care competently.
How to Find Your State’s NPA
Your state’s NPA is public law, and the full text is typically available through your state board of nursing’s website or your state legislature’s online database. The National Council of State Boards of Nursing (NCSBN) maintains a directory at ncsbn.org that links directly to each state’s nurse practice act and associated regulations. Since NPAs are updated through legislative sessions, checking the current version periodically is worth doing, particularly if you practice near state lines or are considering working in a new state.
