OT NBCOT OT Exam Domain Knowledge 2 — Questions and Answers
Question 1: An OT is treating a 55-year-old woman after a total hip replacement (posterior approach) who needs to dress her lower extremities. Which precaution must guide the OT's intervention during dressing training?
- Avoid hip flexion beyond 90°, adduction past midline, and internal rotation (Correct answer)
- Avoid hip extension beyond neutral, external rotation, and abduction
- Maintain hip flexion at exactly 90° throughout all dressing activities
- No restrictions apply as the hip is surgically stabilized after replacement
Correct answer: Avoid hip flexion beyond 90°, adduction past midline, and internal rotation
Posterior approach THA precautions prohibit hip flexion >90°, adduction past midline, and internal rotation to prevent posterior dislocation of the prosthetic hip.
Total hip arthroplasty via the posterior approach (most common) requires precautions for 6–12 weeks to allow capsule healing and prevent posterior dislocation. The three movements to avoid are: (1) hip flexion >90° — prevents posterior subluxation; (2) adduction past midline (crossing legs) — posterior capsule stress; (3) internal rotation — twists the posterior capsule. For lower extremity dressing, the OT teaches: long-handled reacher and sock aid to avoid flexion beyond 90°, seated dressing with operated leg extended, and use of elastic laces. A dressing stick assists with pants. The OT also educates the patient on toilet seat risers, firm cushion use, and avoiding low chairs.
Question 2: A school-based OT is evaluating a 7-year-old with difficulty writing legibly. The teacher reports the child presses very hard with the pencil, fatigues quickly, and has trouble maintaining proper pencil grasp. Which assessment would provide the MOST useful information for intervention planning?
- Evaluation of Written Language (ETCH) for legibility plus sensory processing assessment for proprioceptive feedback issues (Correct answer)
- Vineland Adaptive Behavior Scales to assess overall adaptive functioning
- Beery VMI to assess only visual-motor integration skills
- Direct observation during classroom activities without standardized assessment
Correct answer: Evaluation of Written Language (ETCH) for legibility plus sensory processing assessment for proprioceptive feedback issues
ETCH measures functional handwriting legibility, while proprioceptive assessment explains the hard pressing and fatigue — both are needed for a complete picture.
The Evaluation of Tool Use and Handwriting (ETCH) assesses legibility of alphabet letters, numerals, near-point and far-point copying, dictation, and sentence composition — directly measuring the functional problem (illegibility). Hard pencil pressure and rapid fatigue suggest proprioceptive hyposensitivity (the child cannot feel the pencil adequately, so presses harder to get feedback) or poor grip force modulation. A sensory processing assessment (e.g., Sensory Processing Measure, SP-2) helps identify proprioceptive and tactile processing issues. Intervention may include pencil grips, slant board for wrist positioning, resistive writing surfaces, and a sensory diet. Beery VMI assesses visual-motor integration but not handwriting legibility per se. Vineland measures broad adaptive behavior.
Question 3: An OT is working with a 42-year-old man with C6 spinal cord injury (complete) in an inpatient rehabilitation setting. Which functional skill is MOST realistic as an independent goal for this level of injury?
- Independent manual wheelchair propulsion with gloves and hand rim modifications (Correct answer)
- Independent ambulation with bilateral ankle-foot orthoses (AFOs)
- Independent feeding using a standard spoon without adaptive equipment
- Independent bowel and bladder management without any assistive devices
Correct answer: Independent manual wheelchair propulsion with gloves and hand rim modifications
C6 SCI preserves wrist extensors (ECRB), enabling tenodesis grip and manual wheelchair propulsion with modified hand rims — a realistic independence goal.
At C6 complete SCI, preserved muscles include: wrist extensors (ECRB — key muscle), biceps, deltoids, and partial pectorals. Lost: wrist flexors, finger extensors/flexors, intrinsics. Functional tenodesis grip (passive hand closure when wrist extends) enables manipulation of lightweight objects. For wheelchair propulsion, C6 patients can use manual chairs with gloves and friction-coated or knobbed hand rims. Independent self-care goals: feeding with universal cuff or tenodesis orthosis, upper extremity dressing independently, lower extremity dressing with equipment and extra time. Ambulation is not a functional goal (hip flexors, knee extensors absent). Bowel/bladder require assistance or adapted techniques (digital stimulation is possible at C6 but not truly independent without equipment).
Question 4: An OT is leading a task-oriented group for adults with schizophrenia in a community mental health setting. A client becomes agitated and begins yelling at another group member. What is the MOST therapeutically appropriate immediate response from the OT?
- Calmly redirect the agitated client using a quiet, non-confrontational tone, acknowledge feelings, and offer to step out briefly if needed (Correct answer)
- Ask all group members to share their feelings about the conflict to use it as a therapeutic learning moment
- Immediately terminate the group session and document the incident as a safety concern
- Ignore the behavior to avoid reinforcing it and allow the group to self-regulate
Correct answer: Calmly redirect the agitated client using a quiet, non-confrontational tone, acknowledge feelings, and offer to step out briefly if needed
De-escalation using a calm, non-confrontational approach, emotional validation, and a brief timeout option is the appropriate immediate therapeutic response to agitation.
In a therapeutic group setting, when a client becomes agitated, the OT's priority is safety and de-escalation. Best practice: (1) Use a calm, quiet voice — agitation is contagious and a calm presence is regulating; (2) Acknowledge feelings without judgment ('I can see you're frustrated'); (3) Redirect — offer a concrete choice ('Would you like to step out for a moment or stay?'); (4) Avoid power struggles or confrontational body language. Processing the conflict as a group teaching moment (option B) is valuable but not during the acute agitation. Terminating the group prematurely removes therapeutic opportunity and may reinforce avoidance. Ignoring the behavior is unsafe and not therapeutically indicated.
Question 5: A 28-year-old woman with rheumatoid arthritis reports severe morning stiffness and joint pain in her hands. Using the biomechanical frame of reference and joint protection principles, which recommendation should the OT prioritize?
- Use larger, stronger joints for tasks; avoid sustained grip; use adaptive equipment to reduce joint stress during morning routines (Correct answer)
- Perform high-repetition fine motor exercises in the morning to 'warm up' the joints
- Apply heat to joints immediately before activity to increase inflammation and circulation
- Use the affected hand maximally during morning routines to maintain range of motion
Correct answer: Use larger, stronger joints for tasks; avoid sustained grip; use adaptive equipment to reduce joint stress during morning routines
Joint protection principles in RA include using larger/stronger joints, avoiding sustained grip, and reducing mechanical stress — all while respecting pain and inflammation limits.
Joint protection principles for rheumatoid arthritis are evidence-based strategies to reduce mechanical joint stress, slow deformity progression, and maintain function: (1) Use larger/stronger joints (e.g., push a door with the shoulder rather than fingers); (2) Avoid sustained grip — use loop scissors, built-up handles, jar openers; (3) Avoid ulnar deviation forces — carry bags over the forearm, not in fingers; (4) Spread loads over multiple joints; (5) Respect pain — pain lasting >1 hour post-activity = too much. In the morning when stiffness and inflammation peak, activity should be paced, warmth applied (warm water, paraffin), and adaptive equipment used to minimize joint loading. High-repetition exercise during acute inflammation can worsen joint damage.
Question 6: An OT receives a referral for a 16-year-old with autism spectrum disorder (ASD, Level 2) to address social participation. The MOST occupation-based approach would be to:
- Use interest-based activities in a naturalistic social group to build genuine peer interaction skills (Correct answer)
- Conduct discrete trial training (DTT) drills for greeting and turn-taking behaviors in a therapy room
- Provide a social skills workbook for the adolescent to complete independently
- Focus solely on sensory processing to reduce behaviors that interfere with social participation
Correct answer: Use interest-based activities in a naturalistic social group to build genuine peer interaction skills
Occupation-based OT practice uses the client's interests in naturalistic contexts — not decontextualized drills — to build meaningful social participation skills.
OT's occupation-based approach to social participation uses meaningful, interest-based activities in naturalistic settings to develop genuine social skills. For an adolescent with ASD, this might include a gaming club, art group, or community volunteer activity built around his/her strengths and interests. This contrasts with DTT (behavioral, decontextualized, does not generalize well to real social settings — though ABA has its own evidence base). Workbooks are psychoeducational tools, not occupation-based. Sensory processing is important but addressing it alone doesn't build social participation. The occupation-based model (OTPF-4, MOHO) prioritizes meaningful engagement in real occupational contexts to build competence and identity.
Question 7: An OT is using the Dynamic Interactional Model (Toglia) with a stroke patient who has unilateral neglect. The therapist asks the patient to cross out all stars on a page and then asks 'How many do you think you missed?' This technique is BEST described as:
- Metacognitive strategy training to improve self-monitoring and awareness of performance (Correct answer)
- Errorless learning to prevent consolidation of incorrect responses
- Cognitive retraining using tabletop tasks to remediate neglect directly
- Compensatory scanning training using systematic left-field anchor techniques
Correct answer: Metacognitive strategy training to improve self-monitoring and awareness of performance
Asking patients to predict and self-evaluate their performance is a metacognitive strategy training technique central to Toglia's Dynamic Interactional Model.
Toglia's Dynamic Interactional Model (Multicontextual approach) targets cognitive processing strategies and metacognition rather than specific cognitive deficits. Key techniques include: (1) Prediction — 'How many do you think you missed?' before checking activates self-monitoring; (2) Performance — complete the task; (3) Self-evaluation — 'How many did you actually miss?' Compare prediction to performance; (4) Strategy identification — 'What could you do differently?' This metacognitive loop builds insight and self-regulation, critical for generalization of strategies. It is not errorless learning (which prevents errors to avoid reinforcing mistakes) nor pure compensatory scanning (which teaches systematic left-to-right search). The dynamic, investigative questioning is the signature of Toglia's approach.
