- This limitation in joint mobility will MOST directly interfere with which ADL task?
Answer: Brushing teeth.
Activities like brushing teeth, washing the face, and self-feeding require significant elbow flexion to bring the hand to the head and mouth (typically over 100 degrees). With flexion limited to 60 degrees, the client would be unable to complete this motion. Tying shoes (B) requires hip and trunk flexion. Putting on a jacket (C) requires shoulder rotation and some flexion but not to the same degree. Reaching into a high cabinet (D) requires elbow extension.
- Hector is a 52-year-old IT specialist with major depressive disorder. He lives alone and works hybrid (home and office). Medical history includes mild back discomfort from prolonged sitting. Hector reports difficulty concentrating, forgetfulness, and reduced mental stamina, especially when switching tasks. Body functions affected include attention, working memory, and task initiation; body structures involved include brain systems supporting executive function. He is missing steps when troubleshooting, forgetting to document changes, and struggling to start complex tasks. At home, he leaves dishes undone and forgets to refill prescriptions. Environmental factors include multiple chat notifications, frequent context switching, and limited structure on work-from-home days. Personal factors include high personal standards, worry about job performance, and willingness to use external reminders and routines.
Answer: Impaired attention and working memory reduce follow-through for troubleshooting steps and daily routines.
This question tests the ability to analyze how impairments in body functions and body structures affect occupational engagement. Understanding the impact of physical and cognitive impairments on daily tasks is critical in occupational therapy. In this scenario, the specific impairments such as impaired attention and working memory influence follow-through for troubleshooting and routines. The correct answer effectively links the impairment to its impact on occupational engagement, demonstrating an understanding of the client's needs. A common distractor might fail by assuming a one-size-fits-all solution, such as stating changing computer brands will immediately restore memory and concentration. Teaching strategies include encouraging students to consider both client-specific factors and environmental contexts, and to practice analyzing case studies to refine their clinical reasoning skills.
- Linda is a 76-year-old widow who recently fractured her right hip after slipping on a wet kitchen floor. She underwent surgery 10 days ago and is now home with home health services. Her medical history includes osteoporosis and mild hearing loss (uses hearing aids). She reports sharp pain when standing from low chairs, limited hip movement, and fear of falling. Body structures affected include the right hip joint and healing tissues; body functions impaired include pain, reduced joint mobility, and decreased balance confidence. Linda's daily occupations include toileting, showering in a tub-shower combo, and preparing tea and toast each morning. She is having difficulty transferring on and off the toilet because it is low, and she avoids showering due to stepping over the tub edge. Environmental factors include throw rugs, a low toilet, and a narrow bathroom. Personal factors include strong desire to remain at home, anxiety about another fall, and a daughter who visits weekly to help with groceries.
Answer: Limited hip mobility and pain make low transfers and tub stepping more difficult.

Teaching strategies include encouraging students to consider both client-specific factors and environmental contexts, and to practice analyzing case studies to refine their clinical reasoning skills.
- Which functional complaint is the MOST direct consequence of the impact of AMD on the client's visual body functions?
Answer: "The words in the middle of the page seem to disappear or are distorted."
Age-related macular degeneration specifically affects the macula, which is responsible for sharp, detailed central vision. Therefore, its primary impact is the loss of central vision, leading to scotomas (blind spots) or distortion directly in the line of sight. This would cause words in the center of the visual field to appear blurry, distorted, or missing. Bumping into doorways (B) is characteristic of peripheral field loss (e.g., from glaucoma). Dry eyes (C) is a separate condition. Trouble with low light (D) is a common age-related change but is not the most specific complaint for AMD's primary impact on an activity like reading.
- The client's increased fall risk in low-light conditions is BEST explained by an inability to do what?
Answer: Visually compensate for the loss of joint position sense.
Proprioception is the body's ability to sense its position in space. When this is impaired, people rely more heavily on their visual system to maintain balance. In low-light or dark environments, this visual compensation is not possible, which unmasks the proprioceptive deficit and leads to ataxia and a high risk of falls. The client has sufficient strength (B), so force generation is not the primary issue. Pain perception (C) and thermoregulation (D) are other functions that can be affected by MS but do not explain this specific pattern of falls.
- Based on this observation, the client's difficulty with the cooking task is MOST likely caused by an impairment in which specific cognitive body function?
Answer: Ideational apraxia, affecting the conceptual knowledge of object function and sequence of actions.
The correct answer is B. Ideational apraxia is a deficit in the conceptual system, leading to an inability to understand the use of tools and the sequence of actions for a task. The client's attempt to plug a toaster into a fork demonstrates a fundamental misunderstanding of the objects' functions, which is the hallmark of ideational apraxia. Their inability to describe the function of the objects further supports this.
A: Ideomotor apraxia involves the loss of the motor plan to perform a task, but the knowledge of the object's purpose is intact. The client would know what a toaster is for but would be clumsy or unable to execute the required movements.
C: Constructional apraxia is a difficulty in putting parts together to form a whole, such as assembling a block design, which does not fit the scenario.
D: Anosognosia is a lack of insight into one's deficits, but it does not directly explain the specific error of misusing tools based on a conceptual loss.
- Evelyn is a 68-year-old former bus driver with chronic obstructive pulmonary disease (COPD). She lives with her adult daughter in a second-floor walk-up apartment. Her medical history includes a long history of smoking (quit 5 years ago) and seasonal allergies. Evelyn reports shortness of breath with light activity, fatigue by midday, and needing frequent rest breaks. Body structures involved include the lungs and airways; body functions impaired include breathing endurance and exercise tolerance. Evelyn values leisure and social participation: she used to attend a weekly community dance class and enjoys gardening in shared outdoor plots. Currently, she avoids the dance class because climbing stairs to leave the apartment and sustained movement increase breathlessness. She also limits gardening because bending and carrying small tools make her feel "winded." She is independent with basic self-care but needs extra time for showering and dressing. Environmental factors include multiple flights of stairs, limited elevator access in community buildings, and hot, humid weather that worsens symptoms. Personal factors include strong interest in staying active, worry about embarrassment when she has to stop to catch her breath, and supportive family who can drive her to activities.
Answer: Breathlessness and fatigue limit sustained activity needed for dance and gardening.
This question tests the ability to analyze how impairments in body functions and body structures affect occupational engagement. Understanding the impact of physical and cognitive impairments on daily tasks is critical in occupational therapy. In this scenario, the specific impairments such as breathlessness and fatigue influence dance and gardening. The correct answer effectively links the impairment to its impact on occupational engagement, demonstrating an understanding of the client's needs. A common distractor might fail by assuming a one-size-fits-all solution, such as claiming replacing stairs with a ramp will fully eliminate breathing limitations. Teaching strategies include encouraging students to consider both client-specific factors and environmental contexts, and to practice analyzing case studies to refine their clinical reasoning skills.
- Client with emphysema has O2 sat dropping to 88% while showering. Which body function impairment explains this?
Answer: Impaired gas exchange
Emphysema destroys alveolar walls, so oxygen cannot diffuse efficiently from alveoli into blood. The added oxygen demand of showering makes this gas exchange defect show up as dropping O2 saturation. Reduced cardiac output is tempting, but the primary problem here is at the alveolar-capillary membrane, not the heart's ability to pump.
- Client with MS has leg buckling after a hot shower. This best reflects which impairment?
Answer: Heat-slowed nerve conduction
In MS, demyelinated nerves conduct more slowly when core temperature rises, so a hot shower can transiently worsen leg weakness and buckling. This is Uhthoff phenomenon. Orthostatic blood pooling is tempting because showers involve standing, but the key trigger is heat, not posture or circulation; cooling reverses the symptom.
- During circle time on the floor, how would this specific impairment in neuromuscular function MOST likely affect the child's participation?
Answer: The child will have difficulty maintaining a stable seated position on the floor.
Increased extensor tone in the lower extremities causes the hips and knees to straighten involuntarily. This makes it very difficult for the child to achieve or maintain hip and knee flexion needed for stable floor sitting postures, such as ring sitting or long sitting. The child is likely to lose balance or require external support. Understanding a story (B) is cognitive. Social interest (C) is a psychosocial function. Manipulating pages (D) is an upper extremity fine motor task, which is less affected in spastic diplegia.
- Priya is a 29-year-old graduate student with major depressive disorder that began after a recent move and increased academic pressure. She lives alone and has no significant medical history. Priya reports poor concentration, slowed processing, and difficulty remembering what she read. Body functions affected include attention, working memory, and mental energy; body structures involved include brain systems supporting executive functioning. Her occupational roles include student, friend, and tenant managing her own household. She is falling behind on assignments because she rereads pages multiple times and struggles to organize tasks. She has stopped responding to friends' messages and often forgets appointments unless reminded. Environmental factors include a demanding course schedule, frequent phone notifications, and studying in a busy café due to limited space at home. Personal factors include high self-expectations, shame about asking for help, and interest in building routines to regain control.
Answer: Impaired attention and memory reduce her ability to study efficiently and meet deadlines.
This question tests the ability to analyze how impairments in body functions and body structures affect occupational engagement. Understanding the impact of physical and cognitive impairments on daily tasks is critical in occupational therapy. In this scenario, the specific impairments such as impaired attention and memory influence studying efficiently and meeting deadlines. The correct answer effectively links the impairment to its impact on occupational engagement, demonstrating an understanding of the client's needs. A common distractor might fail by assuming a one-size-fits-all solution, such as stating switching majors will immediately restore memory and organization skills. Teaching strategies include encouraging students to consider both client-specific factors and environmental contexts, and to practice analyzing case studies to refine their clinical reasoning skills.
- This teacher's occupational performance decline is BEST explained by a significant impairment in which specific executive function?
Answer: Perseveration, resulting in the inappropriate repetition of a thought or action.
The correct answer is C. Perseveration is the uncontrollable repetition of a particular response, such as a word, phrase, or action, despite the absence or cessation of a stimulus. The teacher's repetition of phrases and inability to transition from a single detail are classic examples of cognitive perseveration, a hallmark of frontal lobe dysfunction common in frontotemporal dementia.
A: The teacher is able to initiate the lesson, so a deficit in initiation is not the primary problem.
B: While inhibition deficits are common in FTD, the behavior described is one of repetition, not impulsivity.
D: Poor organization may be present, but the specific, defining behavior that explains getting 'stuck' is perseveration.
- This occupational performance issue is a direct result of the loss of muscle power in which specific muscle groups?
Answer: Cervical paraspinal and extensor muscles.
The correct answer is B. The inability to hold the head upright against gravity, resulting in a 'dropped head syndrome,' is caused by severe weakness in the posterior neck muscles—the cervical paraspinals and extensors (e.g., splenius capitis, semispinalis). These muscles work isometrically to maintain an erect head posture. Their failure leads to the chin-on-chest position described, which severely limits visual field, swallowing, and social engagement.
A: Weakness in the anterior neck muscles would cause difficulty with neck flexion, not the inability to hold the head up from a flexed position.
C: While the trapezius has some action on the neck, the primary extensors are the deeper paraspinal muscles.
D: Muscles of mastication are for chewing and are not primarily involved in head posture.
- The client's inability to learn the new strategy and their creation of a false memory are characteristic of impairments in which two body functions?
Answer: Anterograde amnesia and confabulation.
The correct answer is A. Korsakoff syndrome is characterized by severe anterograde amnesia, which is the inability to form new long-term memories. This explains why the client cannot recall the previous day's session. Confabulation, the production of fabricated or distorted memories without the conscious intention to deceive, is the other hallmark symptom. The client's story about creating the visual aid is a classic example of confabulation used to fill in gaps in memory.
B: Retrograde amnesia is the loss of memories from before the brain injury; the scenario focuses on the inability to form new memories.
C: 'Short-term memory deficits' is less precise than anterograde amnesia, and lability (emotional fluctuation) is not described.
D: While declarative memory is affected, the term anterograde amnesia is more specific to the deficit shown. Confabulation is a more precise term than apathy for the memory fabrication described.
- Flaccid hemiplegia causes shoulder subluxation during wheelchair propulsion. Which impairment is most responsible?
Answer: Shoulder abductor weakness
Flaccid hemiplegia takes away the shoulder abductors' support, especially deltoid and supraspinatus, so the humeral head drops during propulsion and subluxates. Poor shoulder position sense may affect awareness of the joint, but it cannot cause the mechanical instability; spasticity is not present in a flaccid limb.
- This client's behavior is a manifestation of an impairment in which body function?
Answer: Asomatognosia.
Asomatognosia is a form of unilateral neglect characterized by a lack of awareness of a part of one's own body. The client's failure to incorporate their left hand into the activity and their statement of surprise indicate a profound lack of awareness of their own limb, which is the definition of this impairment. Bilateral integration (A) is the ability to use two hands together, but the underlying deficit here is awareness, not just coordination. Ideomotor apraxia (B) is the inability to perform a motor task on command. Constructional apraxia (D) is difficulty with drawing or assembling objects.
- Gloria is a 73-year-old woman with COPD who lives with her sister in a retirement community. Medical history includes mild osteoporosis. Gloria reports shortness of breath with moderate activity, fatigue after walking to the dining hall, and needing to pause during longer conversations when she is winded. Body structures affected include lungs and airways; body functions impaired include breathing control during activity and endurance. Gloria values participating in a choir and attending community events. She has stopped going to choir because walking there and singing for extended periods leaves her exhausted. Environmental factors include long corridors, limited benches for resting, and scheduled events back-to-back. Personal factors include strong social motivation, embarrassment about needing breaks, and interest in learning ways to conserve energy while staying involved.
Answer: Breathing limits reduce endurance for walking to events and sustaining singing in choir.
This question tests the ability to analyze how impairments in body functions and body structures affect occupational engagement. Understanding the impact of physical and cognitive impairments on daily tasks is critical in occupational therapy. In this scenario, the specific impairments such as breathing limits influence endurance for walking and singing. The correct answer effectively links the impairment to its impact on occupational engagement, demonstrating an understanding of the client's needs. A common distractor might fail by assuming a one-size-fits-all solution, such as stating attending more events will quickly eliminate fatigue without any pacing. Teaching strategies include encouraging students to consider both client-specific factors and environmental contexts, and to practice analyzing case studies to refine their clinical reasoning skills.
- Omar is a 62-year-old high school teacher with early-stage Parkinson's disease. He lives in a suburban home with his partner and drives to work. Medical history includes high cholesterol controlled with medication. He experiences right-hand tremor at rest, stiffness in his shoulders, and slower initiation of movement. Body functions impaired include motor planning, coordination, and movement speed; body structures involved include brain pathways that regulate movement. Omar's occupational concerns include using a computer mouse for grading, writing on the whiteboard, and managing buttons and zippers when dressing for work. He notices he starts tasks slowly, then rushes to catch up, leading to more mistakes. Environmental factors include large class sizes, limited time between periods, and a need to carry materials between classrooms. Personal factors include pride in his teaching role, mild embarrassment when students notice his tremor, and willingness to try new routines.
Answer: Slowed initiation and tremor can reduce accuracy when writing and using a mouse.
This question tests the ability to analyze how impairments in body functions and body structures affect occupational engagement. Understanding the impact of physical and cognitive impairments on daily tasks is critical in occupational therapy. In this scenario, the specific impairments such as slowed initiation and tremor influence writing and using a mouse. The correct answer effectively links the impairment to its impact on occupational engagement, demonstrating an understanding of the client's needs. A common distractor might fail by assuming a one-size-fits-all solution, such as stating tremor typically improves fine motor precision for writing on the board. Teaching strategies include encouraging students to consider both client-specific factors and environmental contexts, and to practice analyzing case studies to refine their clinical reasoning skills.
- The client's difficulty with the sustained occupation of reading is MOST likely due to an impairment in which specific oculomotor body function?
Answer: Binocular vision, specifically fusional vergence and accommodation.
When evaluating visual complaints after concussion, you need to consider how different oculomotor systems work together to support sustained near tasks like reading. The key symptoms here—words appearing to "float" or "shimmer," eye strain headaches, and difficulty maintaining place—point to problems with eye coordination rather than basic vision.
Answer D is correct because the client's symptoms indicate binocular vision dysfunction, specifically problems with fusional vergence (the ability to keep both eyes aligned on text) and accommodation (focusing ability). Post-concussion syndrome commonly disrupts these coordinated eye movements. When vergence fails, the brain receives slightly misaligned images from each eye, causing text to appear unstable or "floating." The constant effort to maintain single, clear vision leads to the characteristic eye strain and headaches behind the eyes. This explains why a person with perfect 20/20 distance vision still struggles with reading.
Answer A is incorrect because saccadic movements help you jump between words or lines, but wouldn't cause the specific symptoms of floating text or sustained eye strain. Answer B is wrong since visual field defects would cause missing portions of text or bumping into objects, not the shimmering effect described. Answer C is clearly eliminated since the Snellen test confirms normal 20/20 acuity.
Remember that normal distance acuity doesn't rule out near vision problems. On the NBCOT, when you see post-concussion reading difficulties with normal acuity, think binocular vision dysfunction—it's one of the most common but overlooked consequences of brain injury.
- Caleb is a 58-year-old mechanic with COPD who lives in a rural area with his partner. Medical history includes high blood pressure and a prior shoulder strain. Caleb reports frequent shortness of breath with exertion, reduced stamina, and needing rest breaks when walking across the shop. Body structures affected include the lungs and airways; body functions impaired include exercise tolerance and breathing endurance. He values returning to light duties at work and enjoys fishing on weekends. He can complete short tasks at a workbench but becomes winded when carrying tools, climbing a short ladder, or walking long distances on uneven ground to fish. Environmental factors include dust and fumes in the shop, limited nearby parking, and extreme cold in winter that worsens breathing. Personal factors include strong work identity, concern about job security, and willingness to pace activities if it helps him stay employed.
Answer: Reduced stamina limits carrying tools and walking on uneven ground during work and fishing.
