Editing RN Scope of Practice

'''RN scope of practice''' refers to the range of activities that a registered nurse (RN) is educated, licensed, competent, and legally authorized to perform. In the United States, that range is defined primarily by each state's nurse practice act rather than by any single national law, so the specifics differ from state to state. This article is a general study overview for nursing licensure exam preparation. It is not legal advice, and it does not replace the nurse practice act, board of nursing rules, or employer policy in the jurisdiction where a nurse actually practices.

== Overview ==

The RN is a licensed independent practitioner within the domain of nursing. "Independent" here does not mean practicing without a provider, prescriber, or care team. It means that the RN is personally accountable for exercising nursing judgment: deciding what to assess, interpreting the findings, identifying nursing problems, planning and prioritizing interventions, and evaluating whether the plan worked. That judgment function is the defining feature of the RN role and is the reason a large share of licensure exam questions ask the candidate to decide what the nurse should do first, next, or not at all.

Three overlapping sources set the boundaries of any given RN's practice:

* '''Law and regulation.''' The state nurse practice act and the rules the board of nursing writes under it.
* '''Professional standards.''' National standards of practice, such as those published by the American Nurses Association (ANA, 2021), and specialty standards.
* '''Institutional policy and individual competence.''' The employer's policies, position descriptions, and validated competencies.

A useful study rule is that the narrowest of these three governs. A task that is legal under the state nurse practice act but prohibited by employer policy, or that the individual nurse has never been trained to perform, is outside that nurse's practice.

== Legal foundation ==

=== Nurse practice acts ===

Every state and territory has a nurse practice act, a statute passed by the legislature that defines nursing, establishes licensure requirements, creates the board of nursing, and grants the board authority to write and enforce rules (National Council of State Boards of Nursing [NCSBN], 2022). The nurse practice act is the legal ceiling on practice. No employer policy, provider order, or institutional custom can expand it.

Nurse practice acts typically address:

* Definitions of registered nursing, practical or vocational nursing, and advanced practice registered nursing.
* Requirements for licensure by examination and by endorsement.
* Titles and title protection, so that only a licensed person may use the title "registered nurse" or the credential "RN."
* Grounds for discipline, such as practicing beyond scope, diversion of controlled substances, patient abandonment, falsification of records, and practicing while impaired.
* Continuing competence or continuing education requirements.

=== State boards of nursing ===

The board of nursing is the regulatory agency that administers the nurse practice act. Its statutory mission is protection of the public, not advocacy for nurses. Core board functions include issuing and renewing licenses, approving nursing education programs, writing administrative rules, issuing advisory opinions or declaratory rulings on scope questions, investigating complaints, and imposing discipline ranging from a letter of concern to license revocation (NCSBN, 2022).

Boards of nursing are distinct from professional associations. The ANA and specialty organizations set voluntary professional standards and advocate for the profession; they do not license or discipline.

=== Licensure and the NCLEX ===

Entry into RN practice generally requires graduation from a board-approved nursing program, passing the National Council Licensure Examination for Registered Nurses (NCLEX-RN), and meeting the state's background and eligibility requirements. The NCLEX-RN is developed by NCSBN and is used by all United States boards of nursing as the licensure examination for RN candidates (NCSBN, 2023).

=== Multistate licensure ===

Many states participate in the Nurse Licensure Compact, which allows a nurse whose primary state of residence is a compact state to hold one multistate license and practice, in person or by telehealth, in other compact states (NCSBN, 2022). A key study point is that the nurse practices under the laws of the state where the ''patient'' is located, not the state where the nurse lives.

=== Advanced practice is a separate scope ===

Nurse practitioners, clinical nurse specialists, certified registered nurse anesthetists, and certified nurse midwives hold an additional license or recognition beyond the RN license, with a scope that may include diagnosing, ordering diagnostic tests, and prescribing. Prescriptive authority and the degree of physician involvement required vary widely by state. For licensure exam purposes, the baseline RN does not diagnose medical conditions, does not prescribe, and does not independently order diagnostic tests.

== The nursing process and independent clinical judgment ==

The nursing process is the structured problem-solving framework that operationalizes RN judgment. It is commonly taught in five steps, remembered as ADPIE:

# '''Assessment.''' Systematic collection of subjective and objective data.
# '''Diagnosis.''' Analysis of the data to identify the human response the nurse will treat, such as impaired gas exchange or risk for falls. This is a nursing diagnosis, not a medical diagnosis.
# '''Planning.''' Setting priorities and writing measurable, time-limited, client-centered outcomes, then selecting interventions.
# '''Implementation.''' Carrying out or delegating the interventions and documenting the care.
# '''Evaluation.''' Comparing the client's actual response to the expected outcome and revising the plan as needed.

Two features of this framework are heavily tested. First, assessment comes before intervention unless the situation is an immediate life threat with an established protocol, such as absent pulse or an active fire. Second, evaluation loops back to assessment; an intervention that did not produce the expected outcome requires reassessment rather than repetition.

=== Independent versus dependent versus interdependent functions ===

* '''Independent (nurse-initiated) actions''' require no provider order. Repositioning, oral hygiene, incentive spirometry coaching, emotional support, most patient teaching, skin assessment, and fall precautions are examples.
* '''Dependent actions''' require a provider order, such as administering a medication or inserting an indwelling urinary catheter.
* '''Interdependent or collaborative actions''' are carried out with other disciplines, such as implementing a mobility plan with physical therapy.

The RN is obligated to question and to refuse to carry out an order that is illegible, incomplete, contraindicated, or unsafe, and to escalate through the chain of command if the concern is not resolved. Carrying out a clearly erroneous order does not transfer liability to the prescriber.

== Assessment and care planning authority ==

The initial and comprehensive assessment is an RN function and cannot be delegated. This includes the admission assessment, any assessment of an unstable or unpredictable client, and the interpretation of data that requires nursing judgment. Licensed practical or vocational nurses (LPN/LVN) in most jurisdictions may gather focused data, monitor previously assessed clients, and report findings, but they do not perform the initial comprehensive assessment or analyze data to establish the plan of care.

Likewise, the RN owns the plan of care. Formulating nursing diagnoses, setting outcomes, prioritizing problems, revising the plan in response to a change in condition, and performing the final evaluation of care are non-delegable RN activities (NCSBN and ANA, 2019). Other team members contribute data and implement portions of the plan.

Priority-setting frameworks tested at the RN level include airway, breathing, circulation; Maslow's hierarchy, in which physiologic needs generally precede psychosocial needs; the concept of the least stable or most acute client first; and acute or unexpected findings taking precedence over chronic or expected ones.

== Supervisory and delegation role ==

The RN commonly directs the work of LPN/LVNs and unlicensed assistive personnel (UAP). Delegation is the transfer of authority to perform a selected task in a selected situation to a competent individual, while the RN retains accountability for the outcome (NCSBN and ANA, 2019). Supervision is the provision of direction, periodic observation, and evaluation of the person carrying out the delegated task.

Key points for the exam:

* The RN may delegate a ''task'', never the ''nursing process'' itself.
* Assessment, nursing diagnosis, outcome setting, evaluation, and initial teaching are not delegable.
* The stability and predictability of the client largely determine what may be delegated.
* Accountability for the decision to delegate and for the resulting outcome stays with the RN.

Delegation is treated in detail in the companion article on RN delegation and supervision.

== Patient education, advocacy, and documentation ==

Patient and family education is an RN responsibility. The RN assesses readiness and barriers to learning, develops the teaching plan, delivers the initial teaching, and evaluates comprehension, often using teach-back. Others may reinforce teaching that the RN has already provided.

Advocacy obligations include obtaining and honoring the client's expressed preferences, supporting informed consent, and protecting confidentiality. On the question of informed consent, the standard exam distinction is that the provider performing the procedure is responsible for disclosing the nature, risks, benefits, and alternatives, while the nurse witnesses the signature, confirms that the client is competent and not impaired, and confirms that the client's questions have been answered. If the client cannot describe the procedure, the nurse stops and notifies the provider rather than explaining it.

Documentation must be accurate, timely, objective, and complete. Charting care that was not performed, charting in advance, or altering a record is grounds for discipline. The general rule taught for correcting a paper record is a single line through the error, the correction, and the nurse's initials and date, with no obliteration.

== Common limits on RN scope ==

For licensure exam purposes, the baseline RN does not:

* Establish a medical diagnosis.
* Prescribe medications or treatments, except when acting under a valid protocol or standing order that the state permits.
* Independently order diagnostic imaging or laboratory studies.
* Perform procedures for which the nurse has no education, training, or validated competency, even if the state permits RNs generally to perform them.
* Delegate a task that the state has designated as non-delegable.

== Study strategy ==

* When a question asks who should perform a task, sort candidates by client stability and by whether nursing judgment is required.
* When a question asks what the nurse should do first, look for an assessment option unless a life-threatening problem with a known protocol is present.
* Watch for answer choices that have the nurse explaining a procedure, obtaining consent, or prescribing; these are usually outside RN scope.
* Remember that the correct answer reflects the general national standard, not a single state's unusual rule.
* Verify any state-specific detail against the actual nurse practice act before applying it in practice.
