OT NBCOT OT Exam Domain Knowledge 1 — Questions and Answers
Question 1: A 72-year-old man with right hemiplegia following a stroke is referred for OT evaluation. The occupational therapist administers the Functional Independence Measure (FIM). Which domain does the FIM primarily assess?
- Motor and cognitive functional independence in daily activities (Correct answer)
- Muscle strength and range of motion of the affected limb
- Psychological adjustment to disability and quality of life
- Sensory processing abilities and perceptual skills
Correct answer: Motor and cognitive functional independence in daily activities
The FIM assesses 18 items across motor (13) and cognitive (5) domains to measure the level of assistance required for daily activities.
The Functional Independence Measure (FIM) is an 18-item scale divided into motor (13 items: self-care, sphincter control, transfers, locomotion) and cognitive (5 items: communication, social cognition) domains. Each item is rated 1–7, with 7 indicating complete independence and 1 indicating total assist. It quantifies burden of care rather than capacity, making it ideal for tracking rehabilitation progress and discharge planning. In stroke rehabilitation, the FIM is widely used to measure ADL independence and predict functional outcomes.
Question 2: During evaluation of a 5-year-old child with sensory processing disorder, the OT notices the child is hypersensitive to light touch but seeks out deep pressure. Using Ayres' Sensory Integration framework, this pattern most likely indicates:
- Sensory modulation dysfunction with tactile defensiveness and proprioceptive seeking (Correct answer)
- Dyspraxia with poor bilateral integration and sequencing
- Vestibular hyposensitivity requiring linear movement activities
- Auditory processing disorder requiring therapeutic listening programs
Correct answer: Sensory modulation dysfunction with tactile defensiveness and proprioceptive seeking
Tactile hypersensitivity (defensiveness) combined with proprioceptive seeking is a classic sensory modulation dysfunction pattern in Ayres' SI framework.
In Ayres' Sensory Integration theory, sensory modulation disorder occurs when the nervous system fails to regulate responses to sensory input appropriately. Tactile defensiveness is a hyperresponsive pattern in which light touch triggers a fight-or-flight reaction. Simultaneously, proprioceptive seeking (craving deep pressure, heavy work, crashing) reflects hyporesponsivity in the proprioceptive system. The child self-regulates by seeking the organizing input of deep pressure. Intervention involves a 'sensory diet' with controlled proprioceptive input (weighted vests, resistive activities) and gradual desensitization to tactile stimuli in a safe, child-directed environment.
Question 3: An OT is reviewing the Occupational Therapy Practice Framework (OTPF-4) to guide evaluation of a 45-year-old woman with multiple sclerosis. Which of the following best describes an 'occupation' as defined by OTPF-4?
- Activities that have personal meaning and purpose and support participation in life (Correct answer)
- Any task performed during a therapy session to improve motor function
- Movements and physical actions that achieve a functional goal
- Standardized procedures used to assess performance skills
Correct answer: Activities that have personal meaning and purpose and support participation in life
OTPF-4 defines occupations as activities with personal meaning and purpose that support participation in everyday life — the core domain of OT practice.
The OTPF-4 defines occupation as 'the everyday activities that people do as individuals, in families, and with communities to occupy time and bring meaning and purpose to life.' Occupations include ADLs, IADLs, health management, rest and sleep, education, work, play, leisure, and social participation. The framework distinguishes occupation (meaningful life activities) from activity (steps or tasks that make up occupations) and performance skills (observable actions during occupation). Evaluation within the OTPF-4 begins with an occupational profile to understand the client's history, priorities, and desired outcomes, then moves to analysis of occupational performance.
Question 4: An OT administers the Mini-Mental State Examination (MMSE) to an 80-year-old woman and obtains a score of 20/30. Based on this result, which area of performance is MOST likely to be impaired and should guide OT intervention planning?
- Higher-level IADLs such as medication management and financial tasks (Correct answer)
- Basic self-care tasks such as bathing and grooming
- Physical mobility and transfer skills
- Social participation and community integration
Correct answer: Higher-level IADLs such as medication management and financial tasks
An MMSE score of 20–23 suggests mild cognitive impairment, which most directly impacts complex IADLs requiring intact executive function and memory.
The MMSE scores from 0–30, with 24–30 considered normal, 20–23 mild impairment, 10–19 moderate, and below 10 severe. At a score of 20, the patient likely has deficits in orientation, short-term memory, and executive function. These deficits most critically affect complex IADLs: medication management (correct dosing, schedules), financial management (bill paying, checkbook), meal planning, and driving. Basic ADLs (bathing, dressing, grooming) are typically preserved in mild impairment as they rely on procedural memory and learned routines. OT intervention should include compensatory strategies, environmental modifications, and caregiver education for IADL safety.
Question 5: A 35-year-old construction worker is recovering from a traumatic brain injury (TBI) and reports difficulty returning to work. The OT uses the Model of Human Occupation (MOHO) to guide evaluation. Which MOHO concept BEST explains why the worker's strong prior work identity is an asset in rehabilitation?
- Occupational identity, which motivates engagement and goal-directed behavior (Correct answer)
- Habituation, which refers to automatic routines that organize daily behavior
- Volition, specifically personal causation related to skill belief
- Performance capacity based on objective musculoskeletal abilities
Correct answer: Occupational identity, which motivates engagement and goal-directed behavior
MOHO's occupational identity represents one's cumulative sense of who one is as an occupational being, providing motivational drive for rehabilitation.
In MOHO (Kielhofner), occupational identity is the cumulative sense of who one is and wishes to become as an occupational being, shaped by experience and internalized roles. A strong worker identity (e.g., 'I am a skilled tradesman') provides powerful intrinsic motivation — the client wants to return to work because it defines who he is. This differs from: habituation (automated routines/roles — disrupted post-TBI), volition/personal causation (belief in one's ability to succeed — may be threatened by TBI), and performance capacity (objective physical/cognitive capacities). OT intervention using MOHO would leverage this strong occupational identity to set meaningful work-oriented goals and use work simulation activities.
Question 6: An OT is performing a standardized upper extremity assessment on a patient with carpal tunnel syndrome. Which assessment tool is MOST appropriate for measuring functional grip and pinch strength?
- Jamar dynamometer for grip strength and pinch gauge for lateral, tip, and palmar pinch (Correct answer)
- Manual muscle testing (MMT) graded 0–5 for wrist flexors and extensors
- Semmes-Weinstein monofilaments for sensory threshold mapping
- DASH questionnaire for self-reported functional limitations
Correct answer: Jamar dynamometer for grip strength and pinch gauge for lateral, tip, and palmar pinch
The Jamar dynamometer (grip) and pinch gauge (three types of pinch) are the gold-standard objective tools for measuring hand strength in conditions like CTS.
The Jamar hydraulic dynamometer is the gold standard for grip strength measurement, with five handle positions and a protocol of three trials per hand. Normal values are age- and sex-specific. The pinch gauge measures: lateral (key) pinch (thumb pad to lateral index finger), tip-to-tip pinch (thumb tip to index tip), and palmar (three-jaw chuck) pinch. In carpal tunnel syndrome, thenar muscle weakness may reduce thumb opposition and pinch strength. MMT assesses individual muscle groups but is not standardized for functional strength. Semmes-Weinstein tests sensation (important in CTS but separate from strength). DASH measures self-reported function but is not an objective strength measure.
Question 7: A 68-year-old woman with Parkinson's disease is experiencing difficulty with meal preparation. The OT observes bradykinesia, rigidity, and postural instability during the kitchen evaluation. Which adaptive strategy would be MOST beneficial for improving her safety and independence?
- Use of weighted utensils, non-slip mats, loop scissors, and a high stool at the counter (Correct answer)
- Referral to a neurologist to adjust dopaminergic medication before beginning OT
- Intensive repetitive practice of fine motor tasks to rebuild automatic movement patterns
- Prescription of a standard walker to address postural instability during cooking
Correct answer: Use of weighted utensils, non-slip mats, loop scissors, and a high stool at the counter
Adaptive equipment (weighted utensils for tremor, non-slip mats, loop scissors for weak grip, high stool for fatigue/instability) directly compensates for PD motor symptoms during meal prep.
In Parkinson's disease, bradykinesia (slowness), rigidity (resistance to passive movement), and postural instability create significant meal preparation challenges. The OT's role is to use the Compensatory/Adaptive frame of reference to modify tasks and environment: weighted utensils dampen tremor effects; non-slip mats stabilize bowls and cutting boards; loop scissors reduce grip demands; a perch/high stool allows semi-seated work reducing fall risk and fatigue. Medication adjustment is a physician's role. Repetitive practice can improve learned nonuse but does not address the progressive nature of PD motor symptoms. A walker is inappropriate in the kitchen (narrow spaces, hot surfaces); a perch stool is safer.
