1A.1 Nursing Models, Theories & the Nursing Process
Key Takeaways
- Domain I (Nursing Models and Theories) is 8% of the CRRN exam and frames every other domain: it tests how theory, scope/standards, and the nursing process guide rehabilitation care.
- Orem's Self-Care Deficit Theory is the most rehabilitation-aligned model: nursing fills the gap between self-care demand and the patient's self-care ability, moving from wholly compensatory to supportive-educative as function returns.
- King (goal attainment), Rogers (unitary human being), Neuman (systems/stressors), and Roy (adaptation) are the named theories most likely referenced; match the scenario's emphasis to the right theorist.
- The nursing process (assessment, diagnosis, outcomes identification, planning, implementation, evaluation) is the cyclical method underlying all rehabilitation nursing actions and is heavily tested as a step-identification question.
- Rehabilitation nursing practice is governed by an ARN scope and standards of practice and must be evidence-based, patient-centered, and within the RN's legal scope.
Why a Whole Domain on Theory?
Domain I: Nursing Models and Theories is the smallest domain at 8% of the CRRN exam, but it is the conceptual spine of everything else. The RNCB outline frames it as understanding and applying nursing models and theories, the nursing process, and the scope and standards of rehabilitation practice, and incorporating evidence-based research into individualized, patient-centered care. Expect a handful of items that hand you a scenario and ask which theory best explains the nursing approach, or which step of the nursing process an action represents.
High-Yield Nursing Theorists
The outline names theorists explicitly (King, Rogers, Neuman, Orem) and the broader rehabilitation literature adds Roy. You do not need exhaustive detail — you need to match the emphasis of a scenario to the right framework.
| Theory / Theorist | Core idea | Rehabilitation application |
|---|---|---|
| Orem — Self-Care Deficit Theory | Nursing acts when self-care demand exceeds the patient's self-care ability | The defining rehab model: promote self-care, fill only the deficit, fade support as function returns |
| King — Theory of Goal Attainment | Nurse and patient interact and set mutual goals | Shared, patient-centered rehabilitation goal setting |
| Roy — Adaptation Model | The person adapts to stimuli across physiologic, self-concept, role, and interdependence modes | Adjustment to acquired disability and altered roles |
| Neuman — Systems Model | The person is a system defended against stressors by lines of defense | Preventing and buffering the stressors of illness and disability |
| Rogers — Science of Unitary Human Beings | The person is an irreducible energy field in constant interaction with the environment | Holistic, environment-aware, person-centered care |
Orem is the highest-yield: rehabilitation nursing is largely about closing self-care deficits and progressively transferring responsibility to the patient. Orem describes three nursing systems — wholly compensatory (nurse does it), partly compensatory (shared), and supportive-educative (nurse teaches/guides while the patient does it). The arc of a rehabilitation stay moves a patient down that ladder toward supportive-educative as independence grows.
The WHO ICF as a Practice Framework
The contemporary, exam-favored model of disability itself is the World Health Organization International Classification of Functioning, Disability and Health (ICF). It is biopsychosocial, framing disability as the interaction of a health condition with body functions/structures (problems are impairments), activities (activity limitations), and participation (participation restrictions), modified by environmental and personal factors. The ICF replaced the older linear impairment-disability-handicap language and aligns rehabilitation nursing toward participation and the environment, not just the body.
The Nursing Process
The nursing process is the cyclical, evidence-based problem-solving method behind every rehabilitation intervention. The outline lists six steps:
| Step | What happens | Rehabilitation example |
|---|---|---|
| Assessment | Collect functional, physiologic, psychosocial data | Score the FIM; assess skin, swallowing, mood |
| Diagnosis | Identify the nursing problem | Impaired physical mobility; risk for impaired skin integrity |
| Outcomes identification | Define measurable, patient-centered goals | SMART transfer or continence goals |
| Planning | Choose interventions and resources | Bowel program schedule; transfer training plan |
| Implementation | Carry out and coordinate interventions | Teach self-catheterization; reinforce therapy carryover |
| Evaluation | Re-measure and revise | Re-score the FIM; adjust goals at team conference |
A frequent item gives an action and asks for the step: re-scoring the FIM is evaluation; writing the measurable goal is outcomes identification. Another frequent pattern offers an assessment option and an intervention option — unless there is an emergency, the nursing process directs you to assess before intervening.
Evidence-Based, Patient-Centered Practice
Rehabilitation nursing must be evidence-based: integrating the best available research, clinical expertise, and the patient's values and preferences. The CRRN incorporates clinical practice guidelines and current research rather than relying on tradition ("we've always done it this way"). Care is patient- and family-centered — the patient and caregiver are partners in goal setting and decision-making, consistent with King's mutual-goal model and the rehabilitation philosophy of maximizing self-determined function.
Scope and Standards of Practice
Rehabilitation nursing has a defined scope and standards of practice maintained by ARN, plus the broader ANA standards. These define what the rehabilitation RN is accountable for: comprehensive assessment, diagnosis, outcome-driven planning, implementation, evaluation, and standards of professional performance (ethics, education, evidence-based practice, quality, communication, leadership, collaboration). The CRRN practices within the RN legal scope, delegates appropriately while retaining accountability for assessment/teaching/evaluation, and uses the ARN competencies as the benchmark for specialty practice.
On the exam, the "correct" action is one that is within scope, evidence-based, patient-centered, and consistent with the standards — not an out-of-scope or tradition-based choice.
More Theorists You May See
Beyond the core five, the rehabilitation literature draws on a few additional frameworks that occasionally appear in stems. Match the emphasis of the scenario to the theorist rather than memorizing biographies.
| Theory / Theorist | Core idea | Rehab cue in a stem |
|---|---|---|
| Henderson — 14 Basic Needs | Help the patient meet basic needs they cannot meet alone, toward independence | A stem emphasizing assisting with fundamental needs to regain independence |
| Watson — Theory of Human Caring | Caring relationship and 'caritas' as the heart of nursing | A stem emphasizing the therapeutic, caring nurse-patient relationship |
| Peplau — Interpersonal Relations | The nurse-patient relationship moves through orientation, working, and resolution phases | A stem about the developing therapeutic relationship over time |
| Maslow — Hierarchy of Needs | Physiologic and safety needs are met before higher needs | A prioritization stem: airway/skin/safety before self-esteem or participation |
Maslow is quietly high-yield because it underlies prioritization: when a stem offers competing needs, the physiologic and safety options usually outrank psychosocial or self-actualization options — secure the airway, prevent the fall, manage the autonomic dysreflexia before addressing role distress. Recognizing the framework helps you justify the priority answer.
The ARN Competency Model and Rehab Philosophy
The outline references the ARN Rehabilitation Nursing Competency Model, which organizes the specialty around domains such as nurse-led interventions, promotion of successful living, leadership, and interprofessional care. Its philosophical core is consistent with everything above: rehabilitation nursing exists to help people with disability or chronic illness reach their maximum function and self-determined participation, viewing the patient holistically and as an active partner.
When a stem contrasts a paternalistic 'do it for the patient' option with one that builds the patient's capacity and self-management, the competency-model-aligned answer is the latter.
Applying Theory to the Exam (Worked Example)
Consider a stem: 'A nurse and a patient recovering from a stroke sit together and write three specific weekly goals the patient chose, then plan the interventions to reach them.' The emphasis is mutual, interactive goal setting, which points to King's Theory of Goal Attainment rather than Orem (which is about filling self-care deficits) or Neuman (stressor defense).
Contrast that with: 'The nurse performs all hygiene for a newly admitted, weak patient, then over the stay shifts to teaching the patient to do it.' That trajectory across nursing systems is the signature of Orem. Practicing this 'name the emphasis, then match the theorist' move is far more efficient than rote memorization, and it is exactly how Domain I items are written.
Why Domain I Pays Off
Though only about a tenth of the exam, Domain I is low-effort, high-return: the concepts are finite, the question patterns are predictable (name the theory, name the nursing-process step, classify an ICF problem, choose the scope/evidence-based action), and mastery here also sharpens reasoning for the larger clinical domains — because the nursing process and patient-centered, evidence-based, in-scope decision-making thread through every functional-pattern and legislative item on the test.
A rehabilitation patient has competing needs documented at one time: a developing pressure area, anxiety about returning to work, and a desire to lead a peer support group. Using Maslow's hierarchy to prioritize, which need does the nurse address first?
A nurse sits with a patient after a stroke to jointly set three specific, patient-chosen weekly goals and plan the interventions to reach them. Which nursing theory best fits this mutual goal-setting interaction?
A rehabilitation nurse gradually shifts from performing a patient's morning care to coaching the patient through it independently as strength returns. Which nursing theory best explains this approach?
A nurse re-administers the Functional Independence Measure (FIM) at discharge and compares it to the admission score to judge progress. Which step of the nursing process does this represent?
Using the WHO ICF framework, a nurse documents that a patient with a transtibial amputation cannot currently climb the stairs to enter their home. This is best classified as which type of problem?
