- Frequently Asked Questions
- Domain 3 makes up 12% of the CRRN exam - roughly 18 of the 150 scored questions.
- It tests team roles, care coordination, and discharge/transition planning, not clinical Functional Health Patterns content.
- Questions favor scenario formats where you pick the correct team member or transition step, not just define terms.
- The exam has 175 total questions (150 scored, 25 unscored pretest) in a 3-hour window with no scheduled breaks.
What Domain 3 Actually Tests
Domain 3, "The Function of the Rehabilitation Team and Transitions of Care," accounts for 12% of the CRRN exam blueprint - smaller than Functional Health Patterns and Legislative, Economic, Ethical, and Legal Issues, but still enough to represent roughly 18 of the 150 scored items on test day. If you're building a study plan across all four content areas, this CRRN Exam Domains 2026: Complete Guide to All 4 Content Areas resource breaks down how the four domains relate to each other and where each one sits in the overall blueprint.
Where Domain 2 asks you to assess and manage a specific body system or functional pattern, Domain 3 asks a different question entirely: who does what on the rehabilitation team, and how does a patient move safely from one level of care to the next? This is the domain that tests your understanding of the rehab nurse as coordinator - not just clinician.
The Interdisciplinary Rehabilitation Team: Who's Who
A large share of Domain 3 content tests whether you know the scope, responsibilities, and referral triggers for each member of the rehabilitation team. Expect questions that describe a patient scenario and ask which team member should be consulted, or which discipline is responsible for a specific intervention.
Core Rehabilitation Team Members
Candidates must be able to distinguish the scope of each role and recognize when a referral or consult is appropriate.
- Physiatrist / rehabilitation physician: directs the overall medical rehabilitation plan and prognosis
- Rehabilitation nurse (CRRN): coordinates care, reinforces therapy gains, manages complications, educates patient/family
- Physical therapist: mobility, gait, transfers, strength and balance
- Occupational therapist: activities of daily living, upper-extremity function, adaptive equipment, cognitive-perceptual retraining
- Speech-language pathologist: swallowing, communication, cognitive-linguistic deficits
- Rehabilitation psychologist / neuropsychologist: coping, adjustment to disability, cognitive assessment
- Social worker / case manager: discharge planning, insurance navigation, community resources, family support
- Vocational counselor: return-to-work planning and job modification
- Recreational therapist: leisure skills and community reintegration activities
- Dietitian and chaplain: nutritional needs and spiritual/psychosocial support
Exam items often test the difference between overlapping scopes - for example, distinguishing OT's role in upper-extremity ADLs from PT's role in mobility, or recognizing when a rehab psychologist referral is more appropriate than a social work referral. Memorizing job titles in isolation won't be enough; you need to recognize role boundaries embedded inside a clinical vignette.
Team Models: Multidisciplinary, Interdisciplinary, Transdisciplinary
The CRRN exam expects you to distinguish between the three classic team-collaboration models, because each implies a different communication structure and a different role for the rehab nurse.
| Team Model | How It Works | Nurse's Role |
|---|---|---|
| Multidisciplinary | Each discipline evaluates and treats independently; goals set separately | Communicates findings but does not co-develop goals |
| Interdisciplinary | Disciplines collaborate, share information, and set joint patient-centered goals | Coordinates conferences, integrates plans, most common rehab model |
| Transdisciplinary | Roles blur; team members cross-train and share interventions | May perform tasks traditionally owned by another discipline under supervision |
Rehabilitation nursing practice is built primarily on the interdisciplinary model, and the exam will frequently present a scenario asking you to identify the team conference process, goal-setting approach, or communication pattern that best reflects interdisciplinary - not multidisciplinary - collaboration.
Key Takeaway
When a question describes joint goal-setting, shared documentation, and regular team conferences, the answer is almost always "interdisciplinary team model," even if the question doesn't use that exact phrase.
Transitions of Care Across the Continuum
The second half of Domain 3 focuses on moving patients safely between levels of care. You need working knowledge of the full continuum and the clinical criteria that determine placement at each level.
Levels of Care Candidates Must Recognize
- Inpatient rehabilitation facility (IRF): requires tolerance for intensive therapy, typically three hours per day, five days per week
- Long-term acute care hospital (LTACH): for medically complex patients needing extended acute-level care
- Skilled nursing facility (SNF): lower-intensity therapy, longer length of stay tolerance
- Home health: for patients who are homebound but can be managed with intermittent skilled visits
- Outpatient therapy: for patients who can travel and no longer need 24-hour supervision
Transition questions frequently test discharge readiness assessment: Is the home environment safe? Is a caregiver trained and available? Has equipment been ordered? Has the patient demonstrated the skills needed for the next, less-supervised setting? The rehab nurse is often the team member who identifies gaps before a transition is finalized, so expect scenario items where the correct answer is to delay discharge, request further caregiver training, or arrange a home safety evaluation rather than proceed on schedule.
Discharge Planning and Community Reintegration
Discharge planning in rehabilitation nursing starts at admission, not the day before discharge. The exam tests this principle directly by presenting scenarios where early discharge planning prevents a delayed or unsafe transition later.
- Patient and family education: teaching must be tailored to health literacy, cultural background, and readiness to learn - a recurring theme that also touches Functional Health Patterns content covered in CRRN Domain 2: Functional Health Patterns (53%) - Complete Study Guide 2026
- Caregiver training and return demonstration: verifying competence, not just verbal understanding, before discharge
- Community reintegration: driving evaluations, community outings, vocational re-entry, and support group referrals
- Follow-up and continuity: scheduling outpatient therapy, durable medical equipment delivery, and physician follow-up before the patient leaves
- Resource referral: connecting patients with peer mentoring, disability-specific organizations, and financial or housing assistance
Because this domain sits adjacent to care coordination and resource use, some candidates find it blends conceptually with the legal and economic material tested in CRRN Domain 4: Legislative, Economic, Ethical, and Legal Issues (27%) - Complete Study Guide 2026 - the distinction is that Domain 3 tests the clinical coordination process, while Domain 4 tests payer, regulatory, and legal frameworks around that process.
How Domain 3 Questions Are Written
Domain 3 items on the CRRN exam are almost always scenario-based multiple choice, consistent with the exam's overall 175-item format (150 scored plus 25 unscored pretest questions) delivered over a 3-hour session with no scheduled breaks. Rather than asking "define interdisciplinary team," a typical item presents a brief patient case and four plausible next steps, only one of which reflects correct team-role identification or appropriate transition timing.
Common traps include selecting a team member based on job title alone rather than scope of practice, or choosing a discharge disposition based on diagnosis rather than functional status and support system. If you're unsure how the difficulty of this domain compares to the exam overall, How Hard Is the CRRN Exam? Complete Difficulty Guide 2026 covers where candidates typically report the most friction.
Scheduling Domain 3 Into Your Study Plan
Because Domain 3 is worth 12% - smaller than Functional Health Patterns and the legal/economic domain - it shouldn't consume a disproportionate share of your prep calendar. A practical approach is to place it in the middle of your timeline, after you've built clinical assessment knowledge from Functional Health Patterns but before your final review weeks focused on legal and ethical content.
Build Functional Health Patterns first
- This domain carries the most weight (53%), so front-load it
- Reference CRRN Domain 1: Nursing Models and Theories (8%) - Complete Study Guide 2026 alongside it since theory concepts recur throughout
Dedicate a focused block to Domain 3
- Drill team roles and scope-of-practice distinctions with flashcards
- Practice scenario questions on discharge readiness and level-of-care selection
- Review team models until you can identify interdisciplinary versus multidisciplinary instantly
Layer in Domain 4 and full-length practice
- Move into legislative, economic, and ethical content
- Run timed practice sets that mix all four domains to simulate exam-day pacing
For a full week-by-week framework covering all four domains, see the CRRN Study Guide 2026: How to Pass on Your First Attempt, and pair your review with realistic scenario questions using the CRRN practice test platform so you're not just recognizing terms but applying them under time pressure.
How Domain 3 Stacks Up Against the Other Domains
| Domain | Weight | Focus |
|---|---|---|
| Domain 1: Nursing Models and Theories | 8% | Theoretical frameworks guiding rehab nursing practice |
| Domain 2: Functional Health Patterns | 53% | Clinical assessment and management across body systems |
| Domain 3: Rehabilitation Team and Transitions of Care | 12% | Team roles, collaboration models, discharge and transition planning |
| Domain 4: Legislative, Economic, Ethical, and Legal Issues | 27% | Regulatory, payer, and ethical frameworks in rehab nursing |
Because Functional Health Patterns and Legislative/Economic/Ethical/Legal Issues together make up 80% of the blueprint, some candidates are tempted to skip Domain 3 review entirely. That's a mistake - with roughly 18 scored items tied directly to this domain, missing team-role and transition-of-care concepts can meaningfully affect your scaled score relative to the 500-point passing standard.
Key Takeaway
Treat Domain 3 as a focused, high-efficiency study block: the content is narrower than Domains 2 and 4, so a few concentrated review sessions on team roles and transitions can lock in nearly all 18 related questions.
Understanding how this domain fits into the credential overall also matters beyond exam day. Employers hiring for inpatient rehab, LTACH, and skilled nursing coordination roles specifically value CRRN-holders who can manage interdisciplinary communication and safe transitions - a theme explored further in CRRN Jobs and in the broader career discussion at Is the CRRN Certification Worth It?

Frequently Asked Questions
Domain 3 makes up 12% of the exam blueprint. With 150 scored questions total, that works out to approximately 18 questions tied to rehabilitation team function and transitions of care.
It overlaps with case management concepts but is framed around the rehabilitation nurse's coordinating role - team communication, discharge readiness, and safe movement across levels of care - rather than payer or reimbursement processes, which fall under Domain 4.
Multidisciplinary teams work independently with separate goals for each discipline. Interdisciplinary teams - the standard model in rehabilitation nursing - collaborate and set joint, patient-centered goals. Expect the exam to test this distinction directly.
You need enough working knowledge to distinguish overlapping roles (like OT versus PT, or social work versus rehab psychology) inside a clinical scenario, since most Domain 3 items test application rather than pure recall.
Since Functional Health Patterns (53%) and Legislative/Economic/Ethical/Legal Issues (27%) carry far more weight, dedicate proportionally less time to Domain 3, but don't skip it - a focused review block covering team roles, models, and transition criteria is usually enough to cover its content efficiently. Practicing scenario questions on the CRRN practice test platform can help confirm you've closed any gaps.
