All questions

Question 1

During a treatment session, a client reports that their power wheelchair has been intermittently losing power and stopping without warning. The COTA checks that the battery is fully charged.

After ensuring the client is in a safe location, what is the COTA's MOST appropriate next action?

  1. Attempt to open the control module to check for loose wires.
  2. Inform the supervising OTR of the malfunction and recommend that the DME supplier be contacted for repair. (correct answer)
  3. Advise the client to continue using the chair but to stay close to home.
  4. Document the client's report in the progress note and plan to discuss it with the OTR next week.
Explanation: The correct answer is B. An intermittent power failure is a significant safety concern that could strand the client or cause an accident. The COTA's responsibility is to immediately report this equipment malfunction to the OTR. They should also recommend contacting the durable medical equipment (DME) supplier, who is responsible for servicing the chair. A is incorrect as it involves complex repairs outside the COTA's scope. C is unsafe advice. D is incorrect because this issue requires immediate attention, not a delayed discussion.

Question 2

A COTA is performing a quick check of a client's wheelchair fit as part of a positioning program. The COTA notices that the front edge of the seat cushion is digging into the area behind the client's knees (popliteal fossa).

This observation most likely indicates an issue with which aspect of the wheelchair's dimensions?

  1. The seat width is too narrow.
  2. The back height is too low.
  3. The seat depth is too long. (correct answer)
  4. The seat-to-floor height is too high.
Explanation: The correct answer is C. Proper seat depth is measured from the back of the pelvis to the popliteal fossa, minus 1-2 inches. If the seat is too deep, its front edge will press against the sensitive popliteal area, potentially restricting circulation and causing skin breakdown. A would cause pressure on the lateral hips. B would not provide adequate trunk support. D would cause the client's feet to dangle and increase pressure on the posterior thighs.

Question 3

A COTA is working with a client who has a C6 spinal cord injury. The intervention plan, developed by the OTR, includes training the client in independent pressure relief techniques while in a new custom manual wheelchair equipped with a pressure-relief cushion.

What is the MOST effective initial instruction for the COTA to provide to the client for performing pressure relief?

  1. Lean from side to side for one minute every hour.
  2. Perform a full depression weight shift, lifting the buttocks off the cushion, for 30-60 seconds every 30 minutes. (correct answer)
  3. Request that the OTR re-evaluate for a power wheelchair with a tilt-in-space feature.
  4. Check for skin redness at the end of the day before going to bed.
Explanation: The correct answer is B. The standard recommendation for effective pressure relief is to completely offload the ischial tuberosities for 30-60 seconds at least every 30 minutes. A full depression weight shift achieves this. A is incorrect because the frequency is too low. C is incorrect as it is outside the COTA's scope to recommend a completely different mobility system; this would be a collaborative decision with the OTR after other options are trialed. D is a monitoring strategy, not an active pressure relief technique, and the frequency is insufficient.

Question 4

A client is practicing community mobility skills in a manual wheelchair with COTA supervision. The client is having significant difficulty propelling up a standard ADA-compliant ramp and is fatiguing quickly.

Which technique is BEST for the COTA to teach the client to improve efficiency and safety while ascending the ramp?

  1. Push forward using long, smooth strokes while leaning the trunk slightly forward. (correct answer)
  2. Use short, rapid pushes to maintain momentum up the incline.
  3. Turn the wheelchair around and ascend the ramp backwards by pulling on the handrails.
  4. Get a running start at the bottom of the ramp to make the initial ascent easier.
Explanation: The correct answer is A. Using long, smooth strokes is the most biomechanically efficient method for wheelchair propulsion, reducing fatigue and risk of repetitive strain injury. Leaning the trunk forward shifts the center of gravity, which improves stability and makes propulsion up an incline easier. B is incorrect because short, rapid pushes are inefficient and lead to quicker fatigue. C is a technique sometimes used for very steep inclines or descending, but it is not the primary technique for ascending a standard ramp. D is unsafe and can lead to a loss of control.

Question 5

A COTA is implementing an intervention plan for a client with multiple sclerosis who is learning to operate a new power wheelchair with a joystick. The client is frequently oversteering and has difficulty with fine-tuned movements for navigating doorways. The plan includes graded training and adjusting control settings.

To improve the client's control for maneuvering in tight spaces, which adjustment should the COTA make to the joystick settings?

  1. Increase the overall forward speed of the wheelchair.
  2. Decrease the sensitivity of the joystick. (correct answer)
  3. Turn on the 'tremor dampening' feature.
  4. Switch the control from the right hand to the left hand.
Explanation: The correct answer is B. Decreasing the joystick's sensitivity (sometimes called 'throw' or 'gain') will reduce the wheelchair's response to the client's small, erratic movements, making it easier to control and perform fine-tuned maneuvers. A would make control more difficult. C is appropriate for clients with tremors, but the scenario describes oversteering, which is a control issue, not necessarily a tremor issue. D is a significant change that should only be considered after other strategies have failed and in collaboration with the OTR.

Question 6

A COTA is working with a client who has a wheelchair with a tilt-in-space feature. The intervention plan, created by the OTR, indicates using this feature regularly throughout the day for pressure relief and postural management.

When educating the client on the primary therapeutic benefit of the tilt-in-space feature, the COTA should explain that it:

  1. allows the client to stretch their hamstrings and back muscles.
  2. makes it easier for the client to perform independent transfers.
  3. redistributes pressure away from the seating surface while maintaining the client's posture. (correct answer)
  4. allows the chair to be used as a transport device in a vehicle without modification.
Explanation: The correct answer is C. The main purpose of a tilt-in-space feature is to provide pressure relief by shifting the client's weight from the buttocks and posterior thighs to the posterior trunk and head. It does this while maintaining the angles of the hips, knees, and ankles, thus preserving the client's established postural alignment. A describes a benefit of a recline feature, not tilt. B is incorrect as the tilted position makes transfers impossible. D is incorrect as the tilt feature is unrelated to vehicle transport safety standards.

Question 7

The intervention plan for a client with dependent edema in both lower extremities requires the use of elevating leg rests on their wheelchair. The COTA is assisting the client with positioning.

When the COTA elevates the client's legs using the leg rests, what compensatory adjustment may be needed to ensure client stability and prevent sacral sitting?

  1. Slightly reclining the wheelchair backrest. (correct answer)
  2. Removing the client's shoes and socks.
  3. Adding a lap tray to the wheelchair.
  4. Lowering the seat-to-floor height.
Explanation: The correct answer is A. Elevating the legs shifts the client's center of gravity backward and can increase posterior pelvic tilt, leading to sacral sitting or even tipping the chair backward. Slightly reclining the backrest helps to open the hip angle and redistribute weight, maintaining postural stability. B, C, and D do not address the change in the center of gravity caused by elevating the legs.

Question 8

A COTA is working with an adolescent who has cerebral palsy and poor trunk control, resulting in lateral leaning. The client's wheelchair is equipped with lateral trunk supports as part of the seating system.

To correctly implement the positioning plan, the COTA should ensure the lateral supports are placed:

  1. directly under the client's armpits (axilla) to provide maximum leverage.
  2. at the side of the thorax, clear of the axilla, to provide support without interfering with arm function. (correct answer)
  3. low on the trunk, contacting the pelvis to prevent pelvic obliquity.
  4. loosely against the client's trunk, allowing for at least two inches of space for movement.
Explanation: The correct answer is B. Lateral trunk supports should be positioned on the lateral aspect of the thorax to provide stability and prevent leaning. They must be placed inferior to the axilla to avoid impinging on the brachial plexus or restricting arm movement. A is incorrect because placement in the axilla is dangerous and can cause nerve damage. C describes the function of pelvic guides, not trunk supports. D is incorrect as the supports should be snug to provide effective support, not loose.

Question 9

A client who is a new power wheelchair user is practicing crossing a street at a signalized intersection with a COTA.

What is the MOST important safety instruction the COTA should provide for this activity?

  1. Increase the wheelchair's speed to the maximum setting to minimize time in the intersection.
  2. Enter the crosswalk as soon as the traffic light turns green.
  3. Wait for the pedestrian 'Walk' signal and visually scan for turning vehicles before proceeding. (correct answer)
  4. Follow directly behind other pedestrians to ensure drivers see the group.
Explanation: The correct answer is C. Safe street crossing involves multiple steps. The client must wait for the proper pedestrian signal, but also engage in defensive driving by actively looking for potential hazards, such as cars turning right on red or left into the crosswalk. This is the most comprehensive safety practice. A is unsafe as it reduces reaction time. B is incorrect as the client should follow pedestrian signals, not traffic signals. D can be dangerous as it reduces the client's visibility and independent judgment.

Question 10

A COTA is educating a client about the features of their new wheelchair cushion, which has an integrated pommel (medial thigh support).

The COTA should explain that the PRIMARY purpose of the pommel is to:

  1. prevent the client from sliding forward in the chair.
  2. promote neutral pelvic alignment by discouraging posterior pelvic tilt.
  3. maintain hip abduction and prevent the knees from moving together. (correct answer)
  4. provide a handhold to assist with transfers and repositioning.
Explanation: The correct answer is C. A pommel is a positioning device designed to act as a medial knee separator. Its primary function is to maintain the hips in a state of abduction and prevent adduction or a 'scissoring' posture of the lower extremities. A is the function of a wedge cushion or proper seat depth. B is influenced by the overall seating system, not just the pommel. D is an unsafe and incorrect use of a positioning device.

Question 11

A COTA is training an active young adult who uses a lightweight manual wheelchair. The client wants to learn how to navigate across a soft, grassy park lawn to attend an outdoor event.

What is the MOST effective propulsion technique for the COTA to teach this client for navigating this type of soft, uneven terrain?

  1. Lean forward and use short, powerful strokes to push through the grass.
  2. Turn around and pull the wheelchair backwards across the lawn.
  3. Perform a 'wheelie' to lift the front casters off the ground while propelling with the rear wheels. (correct answer)
  4. Ask a friend to provide a push from behind to get across the difficult terrain.
Explanation: The correct answer is C. For a skilled and active wheelchair user, performing a 'wheelie' (balancing on the rear wheels) is the most effective technique for crossing soft terrain like grass or gravel. This lifts the small front casters, which would otherwise dig into the ground and stop the chair's momentum. A is ineffective as the casters will get stuck. B is a possible but less efficient strategy. D promotes dependence, which is counter to the goal of training for independent mobility.

Question 12

A client at high risk for pressure injuries is transitioning from a solid foam wheelchair cushion to an air-cell-based cushion as per the OTR's plan. The COTA is providing education on the new cushion.

In addition to its superior pressure redistribution properties, the COTA should inform the client that the air cushion might also result in:

  1. a less stable seating surface. (correct answer)
  2. better insulation and warmth.
  3. less frequent need for maintenance.
  4. a reduced need for pressure relief lifts.
Explanation: The correct answer is A. While air-cell cushions (like ROHO) are excellent for pressure redistribution, they provide less stability than foam cushions because the user is sitting on a surface of shifting air. This can make transfers more difficult and may be challenging for clients with poor trunk control. B is incorrect as foam provides more insulation. C is incorrect as air cushions require regular monitoring of inflation levels. D is incorrect; clients must still perform regular pressure reliefs regardless of cushion type.

Question 13

During a home health visit, a COTA performs a routine skin check on a client who is a full-time wheelchair user. The COTA discovers a 2 cm area of non-blanchable erythema over the client's right ischial tuberosity that was not present at the last visit.

What is the COTA's MOST important and immediate action?

  1. Apply a protective dressing to the area to prevent further breakdown.
  2. Teach the client to perform more frequent pressure reliefs.
  3. Document the finding and inform the supervising OTR immediately of the change in skin integrity. (correct answer)
  4. Recommend that the family purchase a new pressure-relieving cushion.
Explanation: The correct answer is C. The presence of non-blanchable erythema indicates a Stage 1 pressure injury. This is a significant change in the client's condition that requires immediate reporting to the supervising OTR. The OTR must be involved to re-evaluate the intervention plan, seating system, and client education. A and B are potential interventions, but they should only be implemented after collaborating with the OTR. D is outside the COTA's scope of practice.

Question 14

An ambulatory client with severe arthritis is working with a COTA on community mobility and energy conservation. The client mentions they saw an advertisement for a mobility scooter and asks the COTA if they should get one.

What is the COTA's MOST appropriate response?

  1. "Yes, a scooter would be perfect for you; I can give you a list of vendors."
  2. "A power wheelchair would probably be a better long-term solution."
  3. "That's a good question. It's something you should discuss with the OTR, who can help determine the best mobility options for you." (correct answer)
  4. "You don't need a scooter; we should focus on a walking program instead."
Explanation: The correct answer is C. The COTA's role is to implement interventions, not to assess for, recommend, or prescribe specific assistive technology. When a client raises a question about new or different equipment, the COTA's responsibility is to facilitate communication with the supervising OTR, who can then perform the necessary evaluation. A and B are incorrect because they involve making a specific recommendation, which is outside the COTA's scope. D is dismissive of the client's perceived needs and goals.

Question 15

As part of the discharge planning process, a COTA is providing final training to a client and their family on the care of a new manual wheelchair.

Which basic maintenance task is MOST appropriate for the COTA to teach the client and family to perform regularly?

  1. Realigning the wheel spokes.
  2. Replacing the brake cables.
  3. Checking tire pressure and cleaning the frame. (correct answer)
  4. Patching torn upholstery.
Explanation: The correct answer is C. Checking tire pressure is a simple but critical task that ensures the wheelchair rolls efficiently and safely. Keeping the frame clean helps with inspection for cracks or damage. These tasks do not require specialized tools or skills. A, B, and D are more complex repairs that should be performed by a qualified durable medical equipment (DME) technician.

Question 16

A COTA is providing caregiver education on how to safely transport a client in their wheelchair using the family's accessible van.

What is the MOST critical safety instruction the COTA must convey about securing the client and the wheelchair?

  1. The wheelchair's own positioning belt is sufficient to restrain the client during travel.
  2. The wheelchair must be secured facing sideways in the vehicle to save space.
  3. The wheelchair must be secured to the vehicle with a four-point tie-down system, and the client must be secured with the vehicle's seatbelt. (correct answer)
  4. As long as the wheelchair brakes are locked, no other restraints are needed for short trips.
Explanation: The correct answer is C. This is the standard of practice for safe wheelchair transportation (WC19 standard). The wheelchair itself must be secured by a four-point tie-down system to anchor points in the vehicle floor. The occupant must be restrained by the vehicle's installed seatbelt system (both lap and shoulder belt), not the wheelchair's positioning belt, which is not designed to withstand crash forces. A is incorrect and dangerous. B is incorrect; wheelchairs must be secured facing forward. D is incorrect and extremely dangerous, as brakes will not hold in a collision.

Question 17

A COTA is training a family member to assist a client with right hemiplegia in performing a stand-pivot transfer from their wheelchair to the bed. The COTA is emphasizing key safety steps.

What is the MOST critical instruction regarding the setup of the wheelchair for a safe transfer?

  1. Position the wheelchair on the client's right side, parallel to the bed.
  2. Ensure both wheelchair brakes are locked and the footrests are swung away or removed. (correct answer)
  3. Leave the armrest on the side closest to the bed in place for the client to hold onto.
  4. Instruct the client to keep their feet on the footplates until they begin to stand.
Explanation: The correct answer is B. Securing the wheelchair by locking the brakes is the first and most critical step to prevent it from moving during the transfer. Clearing the area for the feet by swinging away or removing the footrests is essential to prevent trips and allow for proper foot placement. A is incorrect because the wheelchair should be positioned on the client's unaffected (left) side. C is incorrect because the armrest is typically removed to allow for a smoother lateral transfer. D is incorrect as the client's feet must be firmly on the floor before initiating the stand.

Question 18

A client with left hemiplegia is being trained by a COTA to use a one-arm drive manual wheelchair. The drive mechanism with two handrims is on the right side. The client needs to make a left turn.

What should the COTA instruct the client to do with their right hand to execute a left turn?

  1. Push forward on both handrims simultaneously.
  2. Push forward on the inner (smaller diameter) handrim.
  3. Pull back on the outer (larger diameter) handrim.
  4. Push forward on the outer (larger diameter) handrim. (correct answer)
Explanation: The correct answer is D. On a one-arm drive wheelchair, two handrims on one side control both wheels. Pushing both forward propels the chair straight. To turn, the client must engage the wheel on the opposite side. Pushing the outer handrim engages the left wheel, causing the chair to turn left. A would move the chair straight ahead. B would engage the right wheel, causing a right turn. C would cause the chair to turn right while moving backward.

Question 19

A client who uses a manual wheelchair is practicing navigating community environments with a COTA. The client is approaching a heavy, non-automated door that opens toward them.

Which strategy is MOST effective for the COTA to teach the client for independently managing this type of door?

  1. Approach the door head-on, push it open with both hands, and quickly roll through.
  2. Turn around and back into the door to push it open, then pull the chair through.
  3. Approach the door at an angle, turn sideways, pull the door open, and propel through the opening while holding it. (correct answer)
  4. Wait until another person is available to provide assistance with the door.
Explanation: The correct answer is C. For a door that pulls open, approaching sideways allows the user to get close to the handle, pull the door open, and then use their other hand or body to hold the door while propelling through the opening. This is a standard, effective technique for independent mobility. A is incorrect as it describes a technique for a door that pushes open. B is awkward and inefficient. D promotes dependence and is contrary to the goal of independent community mobility training.

Question 20

During an intervention session, a COTA observes that an elderly client consistently slides forward into a sacral sitting posture in their standard wheelchair. This is a new observation not previously noted in the client's chart.

What is the COTA's MOST appropriate initial action?

  1. Order a wedge cushion to place in the chair with the higher end forward.
  2. Instruct the client to reposition themselves every 15 minutes.
  3. Document the observation and report it to the supervising OTR. (correct answer)
  4. Adjust the footplates to a higher position to keep the client's hips flexed.
Explanation: The correct answer is C. The COTA's primary role in this situation is to gather data and report changes in the client's condition or equipment needs to the supervising OTR. Sacral sitting can lead to skin breakdown and indicates a potential problem with seating system fit or client positioning that requires re-evaluation by the OTR. A is incorrect because ordering new equipment is outside the COTA's scope. B is a temporary solution that does not address the underlying cause. D could potentially worsen the problem and constitutes a modification that should first be discussed with the OTR.
