All questions

Question 1

A COTA is leading a group intervention for older adults in an assisted living facility. The goal of the group, as established by the OTR, is to improve dynamic balance to reduce the risk of falls during community outings.

Which group activity would be MOST effective for addressing this goal?

  1. Seated Theraband exercises for upper body strengthening.
  2. Practicing slow, controlled Tai Chi movements. (correct answer)
  3. Tossing a balloon back and forth while remaining seated in a circle.
  4. Reviewing a handout on home safety and fall prevention.
Explanation: Tai Chi involves slow, deliberate weight shifting, rotational movements of the trunk, and coordination of the extremities, all of which are excellent for improving dynamic balance and postural control in a controlled, safe manner. Seated exercises and activities do not adequately challenge standing balance. A handout provides education but is not an active intervention for improving physical balance skills.

Question 2

A COTA is working with a school-aged child who has low muscle tone. The OTR's intervention plan includes improving the child's seated postural control to support participation in classroom activities like handwriting. During the session, the COTA observes the child sitting on a standard classroom chair with a rounded back and a posterior pelvic tilt.

Which action should the COTA take to BEST facilitate a more upright and functional sitting posture?

  1. Provide a lap tray to support the child's forearms.
  2. Place a foam wedge cushion on the chair with the higher end at the back. (correct answer)
  3. Instruct the child to sit on a large therapy ball instead of the chair.
  4. Give the child a weighted vest to wear during the activity.
Explanation: Placing a wedge cushion with the higher end at the back promotes an anterior pelvic tilt, which helps the child maintain a more extended spine and an upright posture for tabletop tasks. This directly addresses the observed postural problem. A lap tray supports the upper extremities but doesn't correct the pelvic and trunk posture. A therapy ball is a dynamic surface that may be too challenging for a child with low tone who needs stability. A weighted vest provides proprioceptive input but does not directly facilitate postural alignment.

Question 3

A client with a traumatic brain injury (TBI) is working on dynamic balance in order to safely pick up objects from the floor. The client can stand independently with a wide base of support but demonstrates instability when attempting to bend over.

Which activity should the COTA introduce as the NEXT step to safely progress the client toward the goal?

  1. Practice stooping to pick up beanbags from the seat of a standard-height chair. (correct answer)
  2. Have the client immediately practice picking up an object from the floor.
  3. Work on tandem standing for 30 seconds to improve static balance.
  4. Have the client hold onto a walker while squatting down.
Explanation: Picking up items from a chair seat is a way to grade the activity. It mimics the motion of picking something from the floor but requires less range of motion and a smaller shift in the center of gravity, making it a safer and more achievable next step. Progressing directly to the floor is too challenging. Tandem standing is a static balance task and does not directly practice the dynamic control needed for stooping. Using a walker is a compensatory approach and does not facilitate the development of independent balance control for the task.

Question 4

A client with multiple sclerosis (MS) is participating in an energy conservation and work simplification program. During an intervention focused on meal preparation, the client, who is standing at the counter, reports a sudden increase in fatigue and leg weakness, causing their postural stability to decline.

What is the COTA's MOST appropriate immediate response?

  1. Encourage the client to finish the task quickly to build endurance.
  2. Modify the task by having the client sit on a high stool at the counter. (correct answer)
  3. Immediately stop the session and document the client's fatigue.
  4. Switch to a fine motor activity that can be done while seated at a table.
Explanation: Modifying the activity to allow the client to sit on a high stool is the best response. It addresses the immediate safety concern related to postural instability and fatigue while still allowing the client to continue with the meaningful occupation of meal preparation, which aligns with the principles of energy conservation. Pushing through fatigue is contraindicated for MS. Stopping the session is an option, but modifying first is preferred if possible. Switching to an unrelated task abandons the client's goal for the session.

Question 5

A COTA is implementing an intervention for a child with cerebral palsy to improve trunk control. The child is positioned prone over a large therapy ball. The goal is to facilitate postural extension against gravity.

Which handling technique should the COTA use to BEST elicit the desired response?

  1. Gently roll the ball backward, bringing the child's feet toward the floor.
  2. Quickly roll the ball side-to-side to stimulate righting reactions.
  3. Gently roll the ball forward, so the child's upper body moves toward the floor. (correct answer)
  4. Hold the ball steady while the child reaches for toys placed on the floor.
Explanation: Gently rolling the ball forward causes the child's center of gravity to shift, prompting a protective response to lift the head and chest against gravity. This active movement strengthens trunk and neck extensors and facilitates the desired postural extension. Rolling the ball backward facilitates flexion. Rolling side-to-side facilitates lateral righting, not extension. Reaching for toys on the floor from this position would also facilitate flexion.

Question 6

A COTA is working with an adolescent client who has idiopathic scoliosis. A key part of the intervention plan developed by the OTR is to strengthen core musculature to improve postural support for the spine.

Which activity would be MOST appropriate for the COTA to implement to target the goal of core strengthening for postural support?

  1. Performing a bird-dog exercise (quadruped opposite arm/leg lifts). (correct answer)
  2. Stretching the hamstring muscles while in a long-sitting position.
  3. Riding a stationary bicycle for 10 minutes.
  4. Squeezing a stress ball to improve grip strength.
Explanation: The bird-dog exercise requires co-contraction of the deep abdominal and back extensor muscles to maintain a neutral spine while the extremities are moving. This directly targets the core stability needed for postural support. Hamstring stretching addresses flexibility, not core strength. Bicycling is primarily a cardiovascular and lower extremity strengthening activity. Squeezing a stress ball is for grip strength.

Question 7

A client with cerebellar ataxia has difficulty maintaining balance, especially on uneven surfaces. The COTA is implementing an intervention to improve dynamic postural control by challenging the client's proprioceptive and vestibular systems, as outlined in the OTR's plan.

Which intervention setup would be MOST effective for this purpose?

  1. Walking back and forth on a hard, level floor.
  2. Practicing sit-to-stand transfers from a raised toilet seat.
  3. Standing on a thick foam mat while reaching for objects. (correct answer)
  4. Sitting on a therapy ball and bouncing gently.
Explanation: Standing on an unstable surface like a foam mat reduces reliable input from joint receptors in the feet and ankles, forcing the client to rely more on their vestibular and visual systems to maintain balance. Adding a reaching task makes it a dynamic activity, which directly addresses the goal. Walking on a level floor provides minimal challenge. Sit-to-stand is a good functional activity but does not specifically target the proprioceptive challenge. Bouncing on a ball provides vestibular input but in a supported sitting position.

Question 8

A client who sustained an incomplete spinal cord injury (T12) is working on maintaining an unsupported sitting balance on the edge of a mat table. The COTA is collaborating with the physical therapist to improve the client's functional independence.

What is the MOST relevant activity for the COTA to introduce to integrate postural control into a meaningful occupation?

  1. Time how long the client can maintain static sitting.
  2. Use tactile cues to activate the client's lower back muscles.
  3. Have the client don a shirt while maintaining balance. (correct answer)
  4. Measure active range of motion of the client's shoulders.
Explanation: Integrating an ADL task like pulling a shirt on over the head challenges the client's sitting balance in a dynamic and functional way. This is the unique contribution of occupational therapy—linking an underlying skill (postural control) to a meaningful occupation. Timing static sitting and measuring ROM are forms of assessment, not intervention in this context. Providing tactile cues is a technique used during the activity, but the activity itself is the key intervention.

Question 9

A COTA is working with a client who recently received a below-knee prosthesis. The client is hesitant to put weight on the prosthetic limb and demonstrates poor postural symmetry when standing. The OTR's plan is to improve balance and weight-bearing tolerance.

Which intervention should the COTA implement FIRST to facilitate symmetrical posture?

  1. Have the client practice walking between parallel bars.
  2. Have the client stand facing a mirror while trying to visually align their shoulders and hips. (correct answer)
  3. Instruct the client to repeatedly step up onto a small step with the intact limb.
  4. Engage the client in a seated task to improve core strength.
Explanation: Using a mirror provides immediate visual feedback, allowing the client to see their own posture and make active corrections to achieve a more symmetrical stance. This is a crucial first step in re-establishing body scheme and facilitating equal weight-bearing before progressing to more dynamic tasks. Walking is too advanced. Stepping with the intact limb encourages weight-bearing on that side only. Seated tasks do not address standing posture.

Question 10

A COTA is working in an early intervention setting with a toddler who has significant hypotonia and delayed postural reactions. The toddler is unable to maintain an upright sitting posture independently on the floor. The OTR has recommended using adaptive seating.

Which seating device would provide the necessary support to facilitate an upright posture while still allowing for some active participation?

  1. A beanbag chair.
  2. A standard high chair with a tray.
  3. A floor sitter with lateral trunk supports and a chest strap. (correct answer)
  4. A child-sized recliner.
Explanation: A floor sitter with lateral supports and a chest strap provides external stability for the trunk and pelvis, allowing the child to maintain an upright posture against gravity. This frees up their hands for play and visual exploration while still requiring them to use their head and neck muscles actively. A beanbag chair or recliner provides poor postural support. A standard high chair may not provide enough specific trunk support for a child with significant hypotonia.

Question 11

A COTA is educating a client with chronic low back pain on proper body mechanics for IADLs, as part of the OTR's intervention plan. The client needs to retrieve a small box from a low shelf in a cabinet.

What instruction BEST reflects correct body mechanics to protect the client's back?

  1. Bend at the waist with straight legs to reach the box.
  2. Perform a golfer's lift by hinging at the hips while extending one leg back. (correct answer)
  3. Twist your torso to the side to grab the box quickly.
  4. Get on your hands and knees to crawl toward the cabinet.
Explanation: A golfer's lift is an ideal technique for picking up a light object from a low surface. It involves hinging at the hips while maintaining a neutral spine, which minimizes strain on the lumbar vertebrae. Bending at the waist, twisting, and crawling are all biomechanically inefficient or potentially harmful strategies for this specific task.

Question 12

A child with delayed development shows inadequate protective extension responses, putting them at risk for injury during falls. The OTR has instructed the COTA to implement activities that facilitate these automatic postural reactions.

Which activity is MOST appropriate for the COTA to use to elicit a protective extension forward response?

  1. Have the child sit on a therapy ball while the COTA gently rocks it backward.
  2. Encourage the child to walk along a line on the floor.
  3. Have the child sit on the floor and play with building blocks.
  4. Have the child sit on a small bench while the COTA gently nudges them forward from the shoulders. (correct answer)
Explanation: A gentle but quick forward nudge while the child is seated will shift their center of gravity and should elicit an automatic forward protective response, where the child puts their hands out in front to 'catch' themselves. This directly and safely targets the desired reaction. Rocking backward elicits a backward response. Walking on a line targets dynamic balance, not protective extension. Playing with blocks is a fine motor task.

Question 13

During a kitchen activity, a COTA notices that an older adult client with a fear of falling frequently holds onto the counter, even when performing tasks that do not require it. This limits the client's ability to use both hands and move efficiently. The OTR goal is to increase independence and reduce reliance on external support.

What is the BEST way for the COTA to modify the environment to facilitate improved postural control?

  1. Instruct the client to let go of the counter.
  2. Arrange the activity so the client is seated at a table.
  3. Bring a rolling walker into the kitchen for the client to hold onto.
  4. Place a high stool behind the client for them to feel without sitting down. (correct answer)
Explanation: Placing a stool directly behind the client provides a sense of security and a 'safety net' without them having to actively use it for support. This psychological reassurance can decrease their fear of falling, encouraging them to let go of the counter and use more active postural control. Simply telling them to let go is not therapeutic. Seating them changes the task and doesn't address standing balance. A walker encourages continued reliance on an external support.

Question 14

A COTA is working with a child who has developmental coordination disorder (DCD). The child has significant difficulty with dynamic balance, which impacts their ability to perform ADLs such as putting on pants while standing.

What is the BEST initial strategy for the COTA to implement to help the child succeed with this task?

  1. Have the child practice by standing on one foot for as long as possible.
  2. Instruct the child to put on their pants while sitting on a chair or the floor. (correct answer)
  3. Tell the child to lean against a wall while lifting one leg.
  4. Provide the child with pants that have an elastic waistband.
Explanation: The best initial strategy is to grade the task down by reducing the balance requirements. Having the child sit removes the need to balance on one leg, allowing them to focus on the motor planning and coordination aspects of the dressing task. This promotes success and reduces frustration. Practicing single-leg standing is a remedial exercise but is decontextualized. Leaning against a wall is a good next step after sitting, but not the initial strategy. Using an elastic waistband modifies the pants but not the postural demands of the task.

Question 15

A COTA is working with a child who has poor postural control and gravitational insecurity. The intervention plan includes the use of suspended equipment to facilitate postural adjustments. The child is positioned in prone on a bolster swing.

What is the COTA's primary therapeutic action to facilitate postural extension and righting reactions?

  1. Gently and slowly move the swing in a linear direction. (correct answer)
  2. Ask the OTR to re-evaluate the child's vestibular processing.
  3. Push the swing as high as the child can tolerate to build confidence.
  4. Add pillows on top of the bolster for comfort.
Explanation: Moving the swing gently and slowly provides controlled vestibular input, which prompts the child to make active postural adjustments, such as lifting their head and upper trunk against gravity (postural extension) to maintain their position. This is a core technique for improving postural control. Asking the OTR for a re-evaluation is not an intervention. Pushing the swing high is likely to be overstimulating and frightening for a child with gravitational insecurity. Adding pillows reduces the need for the child to actively engage their muscles for stability.

Question 16

A client is recovering from a right CVA and demonstrates a fear of falling backward when standing at a sink to perform grooming tasks. The COTA observes the client consistently shifting their weight onto their heels.

What is the MOST effective verbal cue the COTA can provide to facilitate a more stable, forward weight shift?

  1. "Don't be scared, you won't fall."
  2. "Bring your belly button toward the sink." (correct answer)
  3. "Lock your knees to feel more stable."
  4. "Hold onto the counter with both hands."
Explanation: The cue "Bring your belly button toward the sink" provides a concrete, external focus that encourages an anterior weight shift and pelvic tilt, moving the client's center of mass forward over their base of support. This is an effective way to counteract the posterior weight shift. Telling a client not to be scared is not a functional cue. Locking the knees is a poor compensatory strategy that reduces stability. Holding on promotes dependency rather than facilitating active postural control.

Question 17

A client with vestibular dysfunction is being seen in an outpatient clinic. The OTR has designed an intervention plan that includes habituation exercises to decrease dizziness. The COTA is responsible for implementing the session.

Which activity BEST aligns with the implementation of a habituation exercise program?

  1. Teaching the client strategies to avoid movements that provoke dizziness.
  2. Providing a weighted blanket to the client to provide calming deep pressure input.
  3. Guiding the client through repeated, controlled head movements that elicit mild symptoms. (correct answer)
  4. Recommending the use of a cane to improve stability when walking.
Explanation: The principle of habituation is to reduce sensitivity to a stimulus through repeated, controlled exposure. Therefore, the COTA would guide the client through specific movements (like head turns or nods) that bring on mild, tolerable levels of dizziness. Over time, the nervous system adapts, and the dizzy response is reduced. Avoidance strategies, deep pressure, and assistive devices are compensatory and do not address the underlying vestibular sensitivity through habituation.

Question 18

A COTA is working with a client who has right hemiparesis following a CVA. The OTR's intervention plan focuses on improving dynamic postural control by encouraging weight-shifting onto the affected side during functional tasks.

Which activity would be MOST appropriate for the COTA to implement to meet this goal?

  1. Performing passive range of motion to the client's right leg.
  2. Having the client stand and reach for cones placed on their right side. (correct answer)
  3. Engaging the client in a seated balloon-tapping activity.
  4. Having the client walk on a treadmill with handrail support.
Explanation: Reaching for cones placed on the affected (right) side requires the client to actively shift their weight onto the paretic leg, directly addressing the goal of improving dynamic postural control and weight-bearing on that side. Passive range of motion is a preparatory technique and does not involve active postural control. Seated activities do not adequately challenge standing balance. Treadmill walking focuses more on gait pattern and endurance rather than the specific component of controlled, dynamic weight-shifting.

Question 19

An older adult client is recovering from a mild CVA with residual left-sided weakness. The COTA is implementing an intervention to improve dynamic standing balance for IADL participation. The client is currently able to stand at a kitchen counter and stir a bowl with their right hand for 1 minute without loss of balance.

To appropriately grade this activity UP to further challenge the client's dynamic balance, what should the COTA do NEXT?

  1. Have the client stir while standing on a foam pad. (correct answer)
  2. Ask the client to sit on a high stool while stirring.
  3. Provide the client with a reacher to get an item from a cabinet.
  4. Have the client perform the task with their eyes closed.
Explanation: Standing on a foam pad creates an unstable surface, which challenges the client's proprioceptive and vestibular systems, thereby increasing the demand on their dynamic balance control. This is an appropriate next step in grading the activity. Sitting on a stool grades the activity down. Using a reacher is a compensatory strategy, not a remedial one for balance. Closing the eyes would be too significant of a challenge at this stage and should only be introduced after the client masters less demanding balance tasks.

Question 20

A client with Parkinson's disease exhibits significant postural instability and retropulsion when standing to perform lower body dressing. The COTA is implementing strategies to improve safety and facilitate independence during this ADL.

What is the MOST effective technique for the COTA to implement to improve the client's postural stability during this task?

  1. Encourage the client to stand and lean against a wall for support.
  2. Instruct the client to sit on the edge of the bed with a wide base of support. (correct answer)
  3. Provide a long-handled shoe horn and sock aid.
  4. Have the client practice marching in place before getting dressed.
Explanation: Having the client sit on a stable surface like the edge of a bed with feet flat on the floor provides a larger, more stable base of support. This minimizes the balance challenges associated with standing and reduces the risk of backward falls (retropulsion), allowing the client to focus on the dressing task. Leaning against a wall is less stable than sitting. Providing adaptive equipment is a valid compensatory strategy but does not address improving the client's postural stability during the task itself. Marching in place is a good warm-up but does not provide the postural support needed during the actual dressing activity.
