All questions

Question 1

During a home visit, a COTA works with an older adult client who has severe chronic obstructive pulmonary disease (COPD). The COTA observes that the client becomes extremely short of breath and pauses to rest three times while walking the 20 feet from the living room to the bathroom. The client states they avoid showering because it 'wears them out too much.'

The client's difficulty with ADLs is primarily due to a deficit in which body function?

  1. Muscle power functions in the lower extremities.
  2. Emotional functions, specifically anxiety about exertion.
  3. Hematological and respiratory functions, leading to poor endurance. (correct answer)
  4. Voice and speech functions, impacting breathing rhythm.
Explanation: The correct answer is C. COPD directly impacts the function of the respiratory system, limiting oxygen exchange and leading to decreased activity tolerance and endurance. The client's shortness of breath (dyspnea) after minimal exertion is a classic sign of this deficit. Distractor A is incorrect because while deconditioning may cause some weakness, the primary limiting factor described is respiratory, not muscular strength. Distractor B is a common comorbidity, but the physiological shortness of breath is the root cause described, making C the primary factor. Distractor D is incorrect; while speech can be affected by shortness of breath, it is a symptom, not the cause of the poor endurance.

Question 2

A client with rheumatoid arthritis (RA) affecting the hands is working on a cooking activity. The COTA observes that the client has difficulty holding a kitchen knife securely and cannot generate enough force to cut firm vegetables like carrots. The client's metacarpophalangeal (MCP) joints are swollen and show signs of ulnar deviation.

The COTA reports to the OTR that which combination of body function and body structure impairments is limiting the client's performance?

  1. Impaired muscle endurance and compromised structure of the wrist joint.
  2. Impaired muscle power and compromised structure of the MCP joints. (correct answer)
  3. Impaired fine motor control and compromised structure of the distal interphalangeal joints.
  4. Impaired pain functions and compromised structure of the carpal bones.
Explanation: The correct answer is B. The client's inability to generate sufficient force indicates impaired muscle power (grip strength). The observation of swollen MCP joints with ulnar deviation points directly to the compromised integrity and alignment of these specific body structures, which are critical for grasp. Distractor A is incorrect because the issue is described as force generation (power), not sustaining the activity over time (endurance). Distractor C is less accurate because while fine motor control is affected, the problem described is primarily one of force, and the structural impairment is noted at the MCP, not DIP, joints. Distractor D is plausible as pain is common in RA, but the stem focuses on the functional deficit of force generation linked to the observable joint deformity.

Question 3

A COTA is working with a client who has multiple sclerosis (MS). The client begins a light meal preparation task with good energy and coordination. However, after about 10 minutes of standing and chopping vegetables, the client's movements become significantly slower and less coordinated, and they report feeling an overwhelming sense of 'heaviness' and exhaustion. After a 5-minute seated rest break, they are able to resume the task for a short period.

The change in the client's performance is a classic example of the impact of which body function impairment common in MS?

  1. Impaired muscle power that is consistently low.
  2. Impaired motor planning causing confusion during the task.
  3. Impaired muscle endurance, specifically related to nerve fatigue. (correct answer)
  4. Impaired emotional functions leading to decreased motivation.
Explanation: The correct answer is C. The scenario describes a significant performance decline after a short period of activity, followed by some recovery with rest. This pattern is characteristic of the profound fatigue (specifically nerve fatigue or lassitude) experienced by many individuals with MS. It is a deficit in muscle endurance related to the underlying demyelination process. Distractor A is incorrect because the client starts with good coordination, indicating their initial power is adequate; the problem is the inability to sustain performance. Distractor B is incorrect as the decline is physical, not cognitive or related to planning. Distractor D is incorrect because the client's report of 'heaviness' and the recovery with rest point to a physiological, not motivational, issue.

Question 4

A client recovering from a mild concussion reports to the COTA that they feel dizzy and nauseous, especially when they turn their head quickly or look at items on a busy grocery store shelf. The client's visual acuity has been tested and is normal.

These symptoms, which are triggered by head movement and complex visual stimuli, suggest a sensory processing dysfunction related to which body function?

  1. Auditory functions.
  2. Olfactory functions.
  3. Visual field functions.
  4. Vestibular functions. (correct answer)
Explanation: The correct answer is D. The vestibular system, located in the inner ear, is responsible for processing information about movement, head position, and spatial orientation to help maintain balance. Post-concussion, this system can become dysfunctional, leading to symptoms of dizziness, vertigo, and nausea that are exacerbated by head movements or by viewing complex visual environments (visual-vestibular mismatch). Distractor A is incorrect as hearing is not mentioned. Distractor C is incorrect because the problem is not a loss of a part of the visual field but the brain's processing of visual and movement information together. Visual acuity was reported as normal.

Question 5

A COTA is observing a 7-year-old child with autism spectrum disorder (ASD) during a classroom art activity involving finger painting. The child begins to scream and vigorously tries to wipe their hands on their pants as soon as the paint touches their fingertips. The child refuses to touch the paint again, even when their favorite color is offered.

This observed behavior MOST likely indicates an impairment in which body function?

  1. Fine motor control functions, causing frustration with the painting task.
  2. Emotional regulation functions, leading to an inappropriate outburst.
  3. Sensory modulation functions, specifically tactile defensiveness. (correct answer)
  4. Ideational praxis, preventing understanding of the purpose of finger painting.
Explanation: The correct answer is C. The child's extreme, negative reaction to the specific tactile sensation of the paint is a classic presentation of tactile defensiveness, which is a problem with sensory modulation. The sensory input is perceived as aversive. Distractor A is incorrect because the issue is not the ability to control hand movements but the reaction to the sensation. Distractor B is partially true, as the child is dysregulated, but the root cause of the emotional outburst is the sensory experience, making C the more precise and primary answer. Distractor D is incorrect as there is no information to suggest the child does not understand the concept of the activity; the reaction is sensory-based.

Question 6

A client is recovering from a right CVA with resulting left hemiplegia. While practicing upper body dressing, the COTA observes the client attempting to put their right arm into the left sleeve of a shirt that is placed on their lap. The client seems confused about the orientation of the shirt in relation to their own body.

This specific difficulty MOST likely indicates an impairment in which body function?

  1. Visual acuity functions, causing blurred vision.
  2. Ideational praxis, causing inability to conceptualize the task.
  3. Spatial relations functions, affecting perception of objects in relation to self. (correct answer)
  4. Body scheme functions, resulting in neglect of the left arm.
Explanation: The correct answer is C. The client's difficulty in orienting the shirt (an object) to their body demonstrates a problem with spatial relations, a perceptual function often affected after a right CVA. The client is struggling to perceive the relationship between the shirt's parts and their own body parts. Distractor A is incorrect as the problem is not about clarity of vision but about interpreting visual-spatial information. Distractor B is incorrect because the client is attempting the task, suggesting they have the general concept of putting on a shirt. Distractor D, while plausible with left hemiplegia, describes unawareness of one's own body part; the error described is about the relationship between the object and the body, which is more specific to spatial relations.

Question 7

A COTA is working with an adolescent who sustained a complete T4 spinal cord injury. During a transfer board training session, the client is properly positioned but has difficulty judging how much force to use when pushing up with their arms, often over- or under-shooting the target landing spot on the wheelchair. Their vision is unimpaired.

The client's difficulty with modulating force during the transfer is MOST likely related to an impairment in which body function?

  1. Muscle power functions, due to weakness in the upper extremities.
  2. Proprioceptive functions, due to loss of sensation below the injury level. (correct answer)
  3. Vestibular functions, resulting in poor balance and equilibrium.
  4. Motor planning functions, affecting the ability to sequence the transfer.
Explanation: The correct answer is B. Proprioception is the sense of the relative position of one's own parts of the body and the strength of effort being employed in movement. With a T4 SCI, the client has lost sensory feedback, including proprioception, from the trunk and lower body. This makes it difficult to sense body position in space and to grade the force of upper extremity movements needed for a controlled transfer. Distractor A is less likely, as the problem is described as modulating force, not a lack of sufficient strength. Distractor C is incorrect because the core issue is not dizziness or balance reactions but the grading of movement. Distractor D is incorrect as the client is attempting the transfer, suggesting the overall plan is intact, but the execution is poorly controlled due to sensory deficits.

Question 8

A COTA is working in an outpatient setting with a client diagnosed with carpal tunnel syndrome. The client reports frequently dropping their coffee mug and hairbrush at home. During the session, the COTA hands the client a wooden block and observes that the client's grasp appears visually secure, but the block slips from their hand after a few seconds.

Based on this observation, which sensory function is MOST likely impaired and contributing to the client's difficulty with grip?

  1. Pain perception, as the client is avoiding a painful stimulus.
  2. Touch and pressure functions, limiting feedback for grip force modulation. (correct answer)
  3. Temperature sense, affecting the ability to hold warm objects.
  4. Proprioceptive functions, causing poor awareness of wrist position.
Explanation: The correct answer is B. Carpal tunnel syndrome involves compression of the median nerve, which provides sensation to parts of the hand. An impairment in touch and pressure sensation would prevent the client from receiving adequate sensory feedback to know how tightly they are gripping an object, leading them to unknowingly loosen their grasp until the object is dropped. Distractor A is incorrect as the scenario does not mention pain during the grasp. Distractor C is specific to temperature and the problem is described with neutral objects (hairbrush, block). Distractor D is less likely to be the primary cause; while proprioception contributes to motor control, the subtle slipping of an object points more directly to a deficit in cutaneous sensory feedback for grip force.

Question 9

An inpatient COTA is working with an 80-year-old client 3 days after a total hip arthroplasty. The client has been cleared for weight-bearing as tolerated. During a grooming task at the sink, the client becomes lightheaded and pale and reports feeling dizzy. The COTA immediately helps the client to a seated position.

The client's symptoms are MOST indicative of a temporary dysfunction in which body system?

  1. Vestibular system functions, due to changes in head position.
  2. Cardiovascular system functions, related to orthostatic hypotension. (correct answer)
  3. Neuromusculoskeletal functions, as a result of muscle fatigue.
  4. Endocrine system functions, due to an unstable blood sugar level.
Explanation: The correct answer is B. Orthostatic hypotension, a sudden drop in blood pressure when changing to an upright position, is common in postsurgical and older adult populations. The symptoms of lightheadedness, dizziness, and pallor upon standing are classic signs. Distractor A is incorrect because while vestibular issues can cause dizziness, the combination of symptoms, especially pallor, in a post-operative client strongly points to a blood pressure change. Distractor C is incorrect as muscle fatigue would present as weakness or shaking, not typically with pallor and lightheadedness. Distractor D is possible, but orthostatic hypotension is a more direct and common explanation for these specific symptoms in this context.

Question 10

A COTA is assisting a client who sustained a full-thickness burn to the dorsum of their right hand. The client has a healing skin graft and is wearing a custom orthosis. During an activity, the COTA observes that the client has significant difficulty making a full fist and extending their fingers, even with the orthosis removed. The client's active range of motion is much more limited than their passive range of motion.

The limitation in active finger flexion and extension is MOST likely due to the impact of the burn on which structures?

  1. The intrinsic muscles of the hand.
  2. The carpal bones of the wrist.
  3. The extensor tendons on the back of the hand. (correct answer)
  4. The sensory nerves providing feedback from the fingertips.
Explanation: The correct answer is C. A full-thickness burn on the dorsum (back) of the hand can cause the extensor tendons to become adherent to the underlying bone or surrounding scar tissue. This adherence prevents the tendons from gliding properly, which is necessary for both finger extension (tendon shortening) and flexion (tendon passively stretching). This directly limits active movement. Distractor A is less likely as intrinsic muscles are primarily in the palm. Distractor B is incorrect as the burn is to soft tissue, not bone. Distractor D is incorrect because while sensation may be impaired, the primary limitation on movement described is mechanical adherence of the tendons.

Question 11

A COTA is working with a client who has a diagnosis of schizophrenia. During a conversation about the client's goals, the COTA notices that the client's speech is disorganized and frequently shifts from one topic to another without logical connection, making it difficult to understand the client's intended meaning.

This communication difficulty is a primary manifestation of an impairment in which body function?

  1. Voice and speech functions, such as articulation.
  2. Memory functions, causing the client to forget the topic.
  3. Thought functions, specifically the organization and logic of thought. (correct answer)
  4. Attention functions, preventing focus on one conversational topic.
Explanation: The correct answer is C. Disorganized speech, such as loose associations or tangentiality, is considered a formal thought disorder, a primary symptom of schizophrenia. It reflects a disruption in the organization, processing, and expression of thoughts. Distractor A is incorrect because the issue is not the physical production of speech sounds (articulation) but the content and structure of what is being said. Distractors B and D can contribute to communication difficulties, but the illogical shifting of topics is most specifically and directly classified as a deficit in thought functions.

Question 12

A COTA is working with a client who has a complete C6 spinal cord injury. The client is learning to use a tenodesis grasp to pick up small objects. The COTA observes that the client is able to achieve finger flexion by actively extending their wrist, but the grasp is not strong enough to hold a small block.

The ability to perform a tenodesis grasp is dependent on the biomechanical interplay between active wrist extensor muscles and which property of the finger flexor muscles?

  1. Adequate muscle power in the finger flexors.
  2. Normal proprioceptive feedback from the fingers.
  3. Intact motor reflexes in the hand.
  4. Sufficient passive tension in the finger flexors. (correct answer)
Explanation: The correct answer is B. A tenodesis grasp relies on the passive tension of the finger flexor muscles. In a client with a C6 SCI, the wrist extensors are innervated, but the finger flexors are not. When the client actively extends the wrist, the paralyzed finger flexor tendons are passively stretched, causing the fingers to curl into a grasp. If this grasp is weak, it may be due to insufficient passive tension (i.e., the muscles are too lax). Distractor A is incorrect by definition; the finger flexors are paralyzed and lack active muscle power. Distractors C and D are not the primary biomechanical principles that make the tenodesis grasp function.

Question 13

A COTA is working with a client who sustained a traumatic brain injury (TBI) two months ago. During a meal preparation activity, the client can verbally list all the steps to make a sandwich but remains seated and does not begin the task until the COTA provides a direct verbal cue to get the bread. The client requires similar cues to move between each subsequent step.

Based on these observations, which client body function is MOST LIKELY hindering the initiation and sequencing of the activity?

  1. Short-term memory functions, as the client cannot recall the next step.
  2. Executive functions, specifically initiation and organization of action. (correct answer)
  3. Ideomotor praxis, as the client cannot perform the motor acts on command.
  4. Emotional functions, as apathy is preventing task engagement.
Explanation: The correct answer is B. The client's ability to state the steps indicates that memory and knowledge of the task are intact. However, the difficulty starting the task (initiation) and moving from one step to the next without prompting points to a deficit in higher-level cognitive or executive functions. Distractor A is incorrect because the client can verbally list the steps, suggesting memory is not the primary issue. Distractor C is incorrect because ideomotor praxis involves the inability to perform a motor action on command despite understanding it; the client can perform the steps once cued, so the motor plan is intact. Distractor D is a possibility with TBI, but the need for cues at each step points more specifically to a cognitive deficit in initiation and sequencing rather than a general lack of interest.

Question 14

A COTA in a school setting is observing a child with developmental coordination disorder (DCD) in a physical education class. When the teacher asks the students to perform a jumping jack, the child moves their arms and legs out of sync, sometimes moving the arms correctly but not the legs, and vice versa. The child appears frustrated, stating, 'My body won't do what I want it to.'

This observation suggests a primary deficit in which specific motor function?

  1. Muscle tone, resulting in hypotonicity that prevents coordinated movement.
  2. Motor planning or praxis, which affects the ability to conceive and execute a novel motor act. (correct answer)
  3. Joint stability, causing the joints to be too loose for controlled movement.
  4. Control of voluntary movement, specifically related to speed and timing.
Explanation: The correct answer is B. DCD is characterized by deficits in motor planning (praxis). The child knows what a jumping jack is supposed to look like but struggles to sequence and coordinate the bilateral movements required to execute it correctly. The child's statement reflects this disconnect between the idea of the movement and the body's execution. Distractor A is incorrect because while hypotonia can be present in DCD, the primary issue described is the coordination and sequencing of a multi-part action, which is a hallmark of dyspraxia. Distractor C is too specific and not the core deficit. Distractor D is a component of the problem, but 'motor planning' is the broader, more accurate term for the overall deficit described.

Question 15

A client with Parkinson's disease reports to the COTA that they have significant difficulty with dressing tasks in the morning, specifically with buttoning their shirt. The COTA observes that the client's hands have a noticeable tremor at rest, but the tremor subsides when they reach for a button. However, the client's movements are extremely slow and small, making it difficult to align the button with the hole.

The COTA should report to the supervising OTR that which body function is the PRIMARY factor interfering with this client's dressing performance?

  1. Control of voluntary movement, specifically bradykinesia. (correct answer)
  2. Involuntary movement functions, specifically resting tremor.
  3. Muscle endurance functions, leading to fatigue during the task.
  4. Proprioceptive functions, causing poor awareness of finger position.
Explanation: The correct answer is A. The key observation is the client's 'extremely slow and small' movements, which defines bradykinesia, a core motor symptom of Parkinson's disease. This slowness is what is primarily hindering the fine motor task of buttoning. Distractor B is incorrect because the scenario states the tremor (an involuntary movement) subsides during the voluntary action of reaching, meaning it is not the primary interference. Distractor C is incorrect because the scenario describes slow movement from the start, not a decline in performance due to fatigue over time. Distractor D is less likely; while proprioception can be affected, the slowness of movement is the most direct and observable cause of the difficulty described.

Question 16

A client with early-stage Alzheimer's disease is participating in a group activity that involves following a 3-step set of instructions to assemble a small craft. The COTA observes that the client repeatedly asks, 'What was I supposed to do next?' after completing each step, even though the instructions were given just a minute before.

This behavior is a direct manifestation of a deficit in which specific cognitive function?

  1. Working memory. (correct answer)
  2. Procedural memory.
  3. Long-term memory.
  4. Perceptual functions.
Explanation: The correct answer is B. Working memory is responsible for holding and manipulating information for short periods to guide ongoing tasks. The client's inability to retain the 3-step sequence for even a short time while performing the craft points directly to an impairment in working memory. Distractor A, procedural memory, relates to 'how to do things' (like riding a bike) and is often preserved longer in Alzheimer's. Distractor C, long-term memory, relates to past events and is not what is being primarily challenged here. Distractor D is incorrect as the client's difficulty is not in perceiving the craft materials but in remembering the sequence of actions.

Question 17

A COTA is working with a client who recently had a below-knee amputation and is being fitted for a prosthesis. The client reports experiencing a persistent, cramping sensation in their missing foot. The client is distressed and asks if this is normal.

The sensation the client is describing is a manifestation of which specific body function phenomenon?

  1. Impaired proprioceptive functions in the residual limb.
  2. Hypersensitivity of the skin on the residual limb.
  3. Phantom limb sensation related to cortical reorganization. (correct answer)
  4. Impaired pain modulation resulting from nerve damage.
Explanation: The correct answer is C. Phantom limb sensation is the feeling that a missing body part is still present. It can include various sensations, such as cramping, itching, or tingling. It is a common phenomenon thought to be related to the brain's neuroplasticity and the reorganization of the sensory cortex following amputation. Distractor A refers to the sense of position of the remaining limb, not the missing one. Distractor B refers to sensitivity of the existing skin. Distractor D is related but less specific; phantom limb sensation is the specific name for this phenomenon, which can be, but is not always, painful (phantom limb pain).

Question 18

During a chart review for a new client with a diagnosis of fibromyalgia, the COTA notes that the OTR's evaluation highlights widespread musculoskeletal pain, fatigue, and 'fibro fog'. During the initial intervention session, the client reports sleeping poorly and feeling unrefreshed upon waking, which they state makes their pain and concentration worse.

The client's report suggests that their difficulty with daily occupations is MOST likely exacerbated by a disruption in which body function?

  1. Sleep functions. (correct answer)
  2. Cardiovascular functions.
  3. Perceptual functions.
  4. Temperature and pressure functions.
Explanation: The correct answer is A. The client's direct report of poor, non-restorative sleep and its connection to increased pain and cognitive ('fibro fog') symptoms points to a disruption in sleep functions. This is a core feature of fibromyalgia and has a significant cyclical impact on other symptoms and overall occupational performance. While pain (part of sensory functions) and cognitive issues are present, the client's statement specifically identifies poor sleep as a key factor that worsens these other problems, making it a critical body function to consider in the intervention context.

Question 19

A COTA is working with a client who has advanced amyotrophic lateral sclerosis (ALS). The client uses a power wheelchair for mobility and an augmentative communication device. During a supported feeding session, the COTA observes that the client has difficulty forming a bolus and moving it to the back of the mouth, leading to pocketing of food in the cheeks.

This observation points to a significant impairment in which body functions related to eating and swallowing?

  1. Salivary gland functions.
  2. Taste and smell functions.
  3. Gastrointestinal functions.
  4. Oral motor functions. (correct answer)
Explanation: The correct answer is B. ALS is a progressive neurodegenerative disease affecting motor neurons. The observed difficulties—forming a food bolus, moving it posteriorly (oral transit), and clearing the cheeks—are all actions performed by the muscles of the tongue, lips, and cheeks. Weakness and poor coordination of these muscles represent an impairment in oral motor functions. Distractor A is incorrect because while saliva production can be affected, the primary problem described is muscular control. Distractor C relates to digestion after swallowing. Distractor D is incorrect as the problem is with the motor act of managing food, not the sensory experience of it.

Question 20

A COTA is working with a client who has a shoulder impingement syndrome. During an activity that requires the client to reach overhead to a shelf, the client reports a sharp pain in their shoulder as their arm passes between approximately 80 and 120 degrees of abduction. The client is able to complete the motion above this range with less pain.

This specific pattern of pain is MOST indicative of an impairment related to which body structures?

  1. The acromioclavicular joint and surrounding ligaments.
  2. The brachial plexus nerves as they pass through the shoulder.
  3. The glenohumeral joint capsule, suggesting adhesive capsulitis.
  4. The rotator cuff tendons and the subacromial space. (correct answer)
Explanation: The correct answer is B. The description of a 'painful arc' of motion, specifically between about 60-120 degrees of abduction, is a classic clinical sign of subacromial impingement syndrome. In this range of motion, the subacromial space is narrowed, causing compression of the structures within it, most commonly the supraspinatus tendon (one of the rotator cuff tendons) and the subacromial bursa. Distractor A would typically cause pain at the top of the shoulder with cross-body movements. Distractor C (adhesive capsulitis) would typically present with a more global loss of range of motion, not a specific painful arc. Distractor D would typically involve radiating nerve pain, numbness, or tingling.
