All questions

Question 1

A client with an AFO asks why the shoe should be on before the calf strap is tightened. What should the COTA explain?

  1. It prevents ankle rotation
  2. It seats the heel in the shoe (correct answer)
  3. It lets the ankle move freely
  4. It makes the brace fit tighter
Explanation: Putting the shoe on first positions your foot and holds the heel down into the shoe's heel counter, so when the calf strap is tightened the ankle joint stays aligned and the foot is properly seated. It isn't about making the brace fit tighter; that comes from strap tension, not the shoe, and it doesn't let the ankle move freely or mainly prevent rotation.

Question 2

Red marks on a residual limb fade within 10 minutes. What should the COTA teach?

  1. Stop wearing until marks fade
  2. Maintain the current schedule (correct answer)
  3. Tighten up the suspension fit
  4. Apply lotion before each wear
Explanation: Red marks that fade within 10 minutes show the residual limb is tolerating the current prosthetic fit and wear time. No change is needed, so keep the current schedule. Stopping wear until marks fade is wrong because brief, resolving redness is a normal response, not a sign of damage or poor fit.

Question 3

A myoelectric prosthesis user reports intermittent function. What should the COTA teach first?

  1. Wear it only during the day
  2. Apply lotion to the limb
  3. Switch to a body-powered hook
  4. Check battery and electrodes (correct answer)
Explanation: Intermittent myoelectric function usually means the socket electrodes are not making good contact or the battery is low. Teach the user to check the battery charge and electrode contact first, since these are the most common causes of signal dropout. Switching to a body-powered hook is premature because you have not yet ruled out simple correctable problems.

Question 4

A client with a new wrist splint reports new finger tingling. What should the COTA teach?

  1. Stop wearing it; call the OT (correct answer)
  2. Tighten the straps for fit
  3. Wear it only during the day
  4. Massage the hand before wear
Explanation: Finger tingling with a new splint points to nerve compression from the splint. Stop wearing it and contact the OT for readjustment. Tightening the straps is tempting, but it would increase pressure and make symptoms worse.

Question 5

A client cannot remove a suction-socket prosthesis. What should the COTA teach?

  1. Apply lotion to the socket rim
  2. Pull the limb out more quickly
  3. Press the valve release button (correct answer)
  4. Wait for less swelling first
Explanation: A suction-socket prosthesis grips via a vacuum seal. To remove it, press the valve release button to break the seal and let air enter, which releases the suction and lets the limb slide out. Pulling the limb out more quickly is the tempting mistake because it seems forceful, but it risks skin injury and won't defeat suction. Lotion on the rim or waiting for swelling do not address the trapped vacuum.

Question 6

A client with rheumatoid arthritis frequently forgets to wear their resting hand splints at night as prescribed. The client states, "I just don't remember to put them on before I fall asleep." Which strategy should the COTA recommend to improve adherence?

  1. Instruct a family member to wake the client up in the middle of the night to put the splints on.
  2. Suggest the client place the splints on their pillow or nightstand and set a phone reminder for bedtime. (correct answer)
  3. Explain the potential for joint deformities in greater detail to motivate the client.
  4. Advise the client to wear the splints during the day instead of at night.
Explanation: This is a client-centered, problem-solving approach. It addresses the client's stated issue ('I forget') by providing external cues (placing splints in a visible location, using an alarm). This strategy helps establish a new routine and empowers the client without being punitive or disruptive.

Question 7

A COTA is working with a client who has a new below-knee prosthesis. The intervention plan includes training in ADLs. Which is the MOST effective strategy for the COTA to teach the client for lower body dressing?

  1. Don the prosthesis first, then stand to pull up the pants.
  2. Sit on the edge of the bed, dress the prosthetic leg first, then the unaffected leg. (correct answer)
  3. Always stand using a walker to ensure stability while dressing.
  4. Have a caregiver perform lower body dressing to prevent falls.
Explanation: This technique promotes safety and energy conservation. Sitting provides a stable base of support. Dressing the affected (prosthetic) side first is a standard principle that makes it mechanically easier to pull the garment over the less mobile limb, followed by the stronger, more mobile limb.

Question 8

After a COTA explains the wearing schedule for a resting hand splint, the client asks, "So I just wear this whenever my hand feels tired?" This response indicates a misunderstanding. What is the BEST action for the COTA to take next?

  1. Re-explain the schedule using the exact same words but speaking more slowly.
  2. Ask the client to repeat the instructions back in their own words. (correct answer)
  3. Give the client a written handout and ask them to read it later.
  4. Inform the OTR that the client is non-compliant with the instructions.
Explanation: The 'teach-back' method is an evidence-based health literacy strategy. By asking the client to explain the instructions in their own words, the COTA can directly assess comprehension and identify specific areas of misunderstanding. This allows for targeted re-education and ensures the client truly understands the plan.

Question 9

A COTA is training a client with a C6 spinal cord injury, who has active wrist extension but no finger function, to use a universal cuff. Which task would be MOST appropriate to practice during the initial training session?

  1. Picking up a small button.
  2. Holding a toothbrush or eating utensil. (correct answer)
  3. Typing on a standard keyboard.
  4. Squeezing a stress ball.
Explanation: A universal cuff is an orthotic device designed to hold objects for individuals lacking grip strength. Its primary purpose is to enable participation in ADLs like feeding and grooming. Practicing with a toothbrush or utensil is a direct, functional application of the device's intended use and is an appropriate starting point for training.

Question 10

A COTA is instructing the spouse of a client with severe hemiparesis on how to don a resting hand splint. The client has significant edema and mild spasticity in the affected hand. Which instruction is MOST crucial for the COTA to emphasize to the caregiver?

  1. Ensure the splint is applied as tightly as possible to reduce edema.
  2. Check the skin for redness or pressure marks 20-30 minutes after removing the splint. (correct answer)
  3. Only remove the splint once a day for cleaning.
  4. Discontinue use if the client's spasticity increases and do not inform the therapist.
Explanation: For a client with impaired sensation, motor function, and edema, skin integrity is a primary concern. The most crucial instruction is to perform regular skin checks for signs of excessive pressure, such as red marks that do not fade within 20-30 minutes. This indicates a risk for skin breakdown and must be addressed.

Question 11

A COTA is implementing the intervention plan for a client learning to use a new body-powered below-elbow prosthesis. The client has mastered opening and closing the terminal device in isolation. What is the BEST next step in the training process?

  1. Practice picking up and releasing objects of various sizes and weights. (correct answer)
  2. Adjust the harness tension to increase the client's grip strength.
  3. Begin training on a myoelectric prosthesis as an alternative.
  4. Provide a home exercise program for scapular protraction and retraction.
Explanation: Once a client has mastered the basic mechanical control of the prosthesis, the next logical step is to apply this skill to functional tasks. This is known as controls training, which involves using the terminal device to interact with objects. This grades the activity from simple motor control to functional use.

Question 12

A COTA is working with a client who has a static progressive elbow extension orthosis. The intervention plan, created by the OTR, states to advance the angle of the orthosis as tolerated to increase extension. During a session, the client reports no pain or stretching sensation at the current angle. What is the COTA's BEST course of action?

  1. Inform the OTR that the client is ready for a new type of orthosis.
  2. Discontinue the orthosis since it is no longer providing a stretch.
  3. Instruct the client to wear the orthosis for longer periods.
  4. Adjust the orthosis to increase the angle of elbow extension slightly. (correct answer)
Explanation: The purpose of a static progressive orthosis is to apply a prolonged, low-load stretch at the end range of motion. If the client no longer feels a stretch, it means they have gained range and are ready for the orthosis to be adjusted. The COTA is acting within the scope of the intervention plan by making this adjustment.

Question 13

A COTA is teaching a client with a mild cognitive impairment how to follow the wearing schedule for a wrist orthosis. The client has difficulty remembering verbal instructions. Which is the MOST effective strategy for the COTA to use?

  1. Provide a detailed, multi-page handout explaining the schedule.
  2. Create a simplified chart with pictures and checkboxes for the client to use. (correct answer)
  3. Verbally explain the schedule once at the beginning of the session.
  4. Ask the client's physician to explain the importance of the schedule.
Explanation: When working with clients who have cognitive impairments, it is essential to adapt the teaching method. A simplified chart with visual cues (pictures) and an interactive component (checkboxes) breaks down the information into manageable parts and provides a concrete tool to aid memory and tracking, promoting adherence.

Question 14

A client is wearing a volar wrist orthosis that immobilizes their dominant wrist and hand after a fracture. The COTA is providing training for ADLs. Which is the MOST important strategy to teach the client during the initial training sessions?

  1. How to safely remove the orthosis to complete tasks requiring fine motor skills.
  2. One-handed techniques for dressing, grooming, and meal preparation. (correct answer)
  3. Bimanual activities to complete as soon as the orthosis is discontinued.
  4. How to strengthen the non-dominant hand to prevent overuse.
Explanation: When a client's dominant hand is immobilized, their immediate need is to learn how to perform necessary daily activities with their non-dominant hand. Teaching compensatory, one-handed techniques is crucial for maintaining independence and safety during the healing period.

Question 15

A COTA is training a client to use a body-powered prosthesis with a voluntary opening hook terminal device. What is the PRIMARY principle the COTA should teach the client for grasping and holding objects?

  1. The grip force is controlled by the tension of the harness.
  2. The grip force is determined by the number of rubber bands on the hook. (correct answer)
  3. The client must maintain scapular protraction to keep the hook closed.
  4. The client uses muscle signals from the residual limb to control the grip.
Explanation: In a voluntary opening (VO) system, the user actively pulls a cable to open the hook against the resistance of rubber bands. The hook closes automatically when the user relaxes. The force of this closure (the grip force) is determined by the number and strength of the rubber bands. More bands equal a stronger grip.

Question 16

During a training session, a client with a new cosmetic upper extremity prosthesis becomes frustrated and says, "This thing just feels so fake and useless. I hate it." What is the COTA's MOST therapeutic response?

  1. "You'll get used to it over time. Let's keep practicing."
  2. "It sounds like you're really frustrated right now. Can you tell me more about what's not working?" (correct answer)
  3. "Maybe we should ask the OTR if you can get a different type of prosthesis."
  4. "Many people feel that way at first, but it's better than having nothing there at all."
Explanation: This response demonstrates effective therapeutic use of self. It starts by validating the client's feelings ('It sounds like you're really frustrated') and then uses an open-ended question to invite the client to share specific problems. This approach builds rapport and helps move the session toward productive problem-solving.

Question 17

A COTA is implementing an intervention for a client with a new myoelectric transradial prosthesis. According to the OTR's plan, the initial focus is on mastering basic controls. Which activity would be MOST appropriate for the COTA to introduce?

  1. Having the client practice driving with a spinner knob.
  2. Training the client to isolate muscle contractions to open and close the terminal device. (correct answer)
  3. Teaching the client how to replace the battery and clean the socket.
  4. Simulating a bimanual activity like tying shoelaces.
Explanation: The foundational skill for using a myoelectric prosthesis is the ability to generate and isolate the specific muscle contractions (e.g., wrist flexors and extensors in the residual limb) that are used to control the electrodes. Mastering this step is essential before progressing to functional use or other management tasks.

Question 18

A client with a custom-molded resting hand splint calls the clinic and tells the COTA that a red area has appeared on their ulnar styloid and it does not disappear after 30 minutes of removing the splint. What should the COTA instruct the client to do FIRST?

  1. Pad the area with cotton balls and continue to wear the splint.
  2. Stop wearing the splint and make an appointment for an adjustment with the OTR. (correct answer)
  3. Try to bend the plastic away from the red area yourself.
  4. Apply an ice pack to the red area and put the splint back on.
Explanation: A red area that does not blanch or fade after 20-30 minutes is a sign of a Stage 1 pressure ulcer, indicating excessive pressure from the orthosis. The safest course of action is for the client to stop wearing the device to prevent further skin damage and to schedule an appointment for reassessment and adjustment by the supervising OTR.

Question 19

During a follow-up visit, a client who had significant edema when their wrist cock-up splint was fabricated now reports that the splint feels very loose. The COTA observes that the client's edema has substantially decreased. What is the COTA's MOST appropriate action?

  1. Remold the entire splint to fit the client's current arm size.
  2. Add new padding to the interior of the splint to make it fit better.
  3. Consult with the supervising OTR about the change in fit. (correct answer)
  4. Instruct the client to tighten the straps as much as possible.
Explanation: A significant change in the fit of a custom orthosis due to physiological changes (like decreased edema) requires re-evaluation. While a COTA can make minor adjustments, the decision to pad, adjust, or completely refabricate the orthosis requires the clinical reasoning of the OTR. The COTA's role is to identify the issue and collaborate with the supervisor.

Question 20

A COTA is providing the initial training session for a client who has just received a custom-fabricated wrist cock-up orthosis for carpal tunnel syndrome. What is the MOST important information to provide to the client during this session?

  1. The biomechanical principles behind the orthosis design.
  2. The specific wearing schedule and precautions for skin inspection. (correct answer)
  3. A list of alternative treatment options if the orthosis is ineffective.
  4. Detailed instructions for adjusting the straps for a tighter fit.
Explanation: The most critical information for a client during the initial orthosis training session is related to safety and adherence. This includes the prescribed wearing schedule, instructions on how and when to perform skin checks to prevent pressure sores, and precautions. This information ensures the client uses the device correctly and safely.
