All questions

Question 1

A client has a thermoplastic long arm orthosis following an elbow fracture. The client asks the COTA for instructions on how to keep the orthosis clean.

What is the MOST appropriate instruction for the COTA to provide?

  1. Put the orthosis in the dishwasher on a gentle cycle once a week.
  2. Wipe the inside and outside with a cloth dampened with lukewarm water and mild soap. (correct answer)
  3. Spray it with a disinfectant aerosol and let it air dry completely.
  4. Clean it with rubbing alcohol to kill any bacteria.
Explanation: Thermoplastic materials can be damaged by high heat (like in a dishwasher) or harsh chemicals (like alcohol or some disinfectants). The safest and most effective method for cleaning is using lukewarm water and mild soap, then allowing it to dry completely before reapplication. This prevents skin irritation and damage to the orthosis material.

Question 2

A COTA is educating a client with De Quervain's tenosynovitis on the use of a forearm-based thumb spica splint, as recommended by the OTR. The client will wear the splint during daily activities to reduce pain.

Which instruction is MOST important for the COTA to provide to the client regarding the use of this splint?

  1. Wear the splint continuously for 24 hours a day to ensure the fastest recovery.
  2. Remove the splint several times a day to perform AROM exercises for the thumb and wrist.
  3. Remove the splint for all hygiene tasks and ensure the skin is completely dry before reapplying. (correct answer)
  4. Discontinue use immediately if there is any reduction in grip strength.
Explanation: Proper hygiene and skin care are critical for clients using an orthosis. Instructing the client to remove the splint for cleaning and to thoroughly dry the skin prevents maceration and skin breakdown. A is incorrect as continuous wear is not always indicated and depends on the specific protocol from the OTR. B is also protocol-dependent; the OTR would specify the type and frequency of exercises. D is incorrect because a reduction in grip strength is an expected outcome of immobilizing the thumb, not a reason to discontinue use.

Question 3

A COTA is fitting a resting hand splint for a client who had a CVA and presents with moderate flexor spasticity in the affected hand. The OTR fabricated the splint to maintain joint alignment and prevent contractures. While attempting to apply the splint, the COTA notices a blanching red area over the ulnar styloid.

What is the COTA's BEST initial response?

  1. Apply the splint anyway and inform the OTR at their next meeting.
  2. Force the client's hand into the splint to overcome the spasticity.
  3. Remove the splint, document the area of concern, and notify the OTR before reapplying. (correct answer)
  4. Place a piece of moleskin over the red area and then reapply the splint.
Explanation: A blanching red area indicates excessive pressure that could lead to skin breakdown. The COTA's priority is client safety. The correct action is to remove the source of pressure, document the finding, and consult with the supervising OTR for modification. The OTR is responsible for making adjustments to the custom splint. A and B risk client injury. D is a temporary solution but does not address the root cause of the poor fit, and applying it without consulting the OTR is inappropriate.

Question 4

A COTA is teaching a client with rheumatoid arthritis and significant MCP joint ulnar deviation to use a soft, prefabricated ulnar deviation splint. The client has pain and decreased dexterity in their fingers and is struggling to manage the hook-and-loop straps.

What is the MOST helpful adaptation the COTA can provide at this time?

  1. Recommend a different style of splint that has no straps.
  2. Add a D-ring or a loop of material to the end of the straps. (correct answer)
  3. Tell the client to ask a family member to help them with the straps each time.
  4. Cut the straps off and replace them with elastic shoelaces.
Explanation: Adding a D-ring or a simple loop to the end of the straps is an appropriate, low-tech adaptation that can significantly improve the client's ability to grasp and pull the straps independently. This promotes independence and is within the COTA's scope. A involves recommending a different device, which is the OTR's role. C promotes dependence, which is contrary to the goals of occupational therapy. D is an inappropriate modification that would alter the function and fit of the splint without OTR approval.

Question 5

A client is 3 days post-operation for a flexor tendon repair in their index finger. The OTR's intervention plan specifies a dorsal blocking splint to be worn at all times. The client tells the COTA they need to remove the splint to take a shower.

What is the COTA's BEST response?

  1. Help the client remove the splint and reapply it immediately after the shower.
  2. Tell the client to skip showering until their next appointment with the surgeon.
  3. Reinforce the surgeon's protocol for continuous wear and provide a plastic bag to cover the splint. (correct answer)
  4. Check the OTR's notes to see if splint removal for hygiene is allowed.
Explanation: Flexor tendon repair protocols are very strict to protect the delicate surgical repair. A dorsal blocking splint must be worn continuously. The COTA's role is to implement and reinforce the established plan. Providing a bag to keep the hand and splint dry is the standard, safe procedure that maintains the integrity of the protocol while allowing the client to complete a necessary ADL. A violates the protocol and risks rupturing the tendon. B is an unreasonable instruction. D is unnecessary, as these protocols are standard and the COTA should know not to remove the splint without explicit orders.

Question 6

A teenager is non-compliant with wearing a thumb spica splint prescribed for a scaphoid fracture. When the COTA asks about it, the client says, "It's ugly and my friends make fun of it." The OTR's plan is to improve compliance.

Which client-centered strategy is MOST appropriate for the COTA to implement?

  1. Explain the severe medical consequences of not wearing the splint.
  2. Contact the client's parents and instruct them to enforce the wearing schedule.
  3. Collaborate with the client to choose colored straps or allow them to decorate the splint. (correct answer)
  4. Tell the client they cannot participate in therapy until they wear the splint consistently.
Explanation: A client-centered approach involves understanding the client's perspective and collaborating on solutions. For a teenager, aesthetics and peer acceptance are highly motivating factors. Allowing the client some control over the splint's appearance can significantly increase buy-in and compliance. This action aligns with implementing the OTR's goal of improving compliance. A uses fear, which is often ineffective. B removes autonomy from the client. D is punitive and not therapeutic.

Question 7

A COTA is working with a client who has a mallet finger injury. The client has been provided with a small finger gutter splint to keep the distal interphalangeal (DIP) joint in continuous extension.

What is the MOST critical instruction for the COTA to emphasize to the client?

  1. The splint can be removed for short periods to allow the skin to breathe.
  2. It is essential to keep the DIP joint fully extended at all times, even when cleaning the finger. (correct answer)
  3. The splint should be tight enough to prevent any blood flow to the fingertip.
  4. Active flexion and extension exercises of the DIP joint should be performed daily.
Explanation: The primary goal of a mallet finger orthosis is to allow the extensor tendon to heal without being stretched. Any flexion of the DIP joint, even for a moment, can disrupt the healing process. Therefore, the most critical instruction is to maintain the joint in continuous extension. A and D directly contradict the healing protocol. C is dangerous and would lead to tissue damage.

Question 8

A COTA is working with an elderly client who was prescribed a soft wrist brace for nighttime use to manage arthritis pain. The client lives alone and has poor vision and decreased fine motor coordination.

Which feature of the orthosis should the COTA pay particular attention to during the fitting and education session?

  1. The color and aesthetic appearance of the brace.
  2. The breathability of the material for warm nights.
  3. The ease of managing the fastening system independently. (correct answer)
  4. The specific angle of wrist extension the brace provides.
Explanation: Given the client's functional limitations (poor vision, decreased coordination) and living situation, their ability to independently manage the orthosis is paramount. The COTA must ensure the client can successfully don and doff the brace, focusing on the fastening system. If the client cannot manage the straps, the orthosis will not be used. While B and D are relevant features, they are secondary to the client's ability to actually use the device. A is the least clinically relevant factor.

Question 9

During a session, a COTA checks the fit of a client's thermoplastic resting hand splint and notices a persistent red mark over the distal ulna. The OTR who fabricated the splint is out of the office for the day.

Which action is within the COTA's scope of practice?

  1. Use a heat gun to spot heat and flare out the area of the splint causing pressure.
  2. Instruct the client not to wear the splint until the OTR can assess it. (correct answer)
  3. Grind the edges of the splint in the affected area with a sanding tool.
  4. Re-mold the entire splint to better fit the client's forearm.
Explanation: Client safety is paramount. A persistent red mark indicates a high risk for skin breakdown. Since the OTR is unavailable to make modifications, the safest course of action is to instruct the client to stop wearing the device to prevent injury. The COTA must then ensure the OTR is notified. A, C, and D involve modifications that require advanced training and are typically performed by the OTR who fabricated the orthosis, unless the COTA has demonstrated service competency and it is permitted by the facility and state practice acts.

Question 10

The OTR has determined that a client with rheumatoid arthritis would benefit from wearing bilateral wrist-hand orthoses during sleep to reduce inflammation and pain. The OTR gives the COTA the wearing schedule and asks the COTA to provide client education.

What is the COTA's PRIMARY role during this education session?

  1. To determine if a different type of orthosis would be more comfortable.
  2. To ensure the client can correctly don and doff the orthoses and understands the wear schedule. (correct answer)
  3. To modify the wearing schedule based on the client's reported sleep patterns.
  4. To fabricate a new set of orthoses if the client reports any discomfort.
Explanation: The COTA's primary role in implementing an orthosis plan is to ensure the client can manage it effectively. This includes teaching them how to put it on (don) and take it off (doff) correctly and verifying their understanding of the prescribed wearing schedule. A, C, and D all involve assessment, plan modification, or fabrication, which are responsibilities of the OTR.

Question 11

An OTR has recommended silver ring splints for a client with rheumatoid arthritis to correct swan neck deformities and improve hand function. The COTA is responsible for educating the client on their use.

What is a primary functional benefit the COTA should highlight to encourage the client's use of the splints?

  1. They will completely reverse the joint deformities over time.
  2. They prevent PIP joint hyperextension, which allows for improved finger flexion for grasping objects. (correct answer)
  3. They provide warmth to the joints, which will significantly decrease arthritis pain.
  4. They are a permanent solution and will not need to be removed once fitted.
Explanation: Silver ring splints for swan neck deformities work by blocking PIP joint hyperextension. By preventing the PIP from 'locking' back, the splint facilitates active PIP flexion, which is essential for making a fist and grasping objects. This is a direct functional benefit. A is incorrect; they prevent progression and improve function but do not reverse fixed deformities. C is incorrect; they are not designed to provide warmth. D is incorrect; they must be removed for hygiene.

Question 12

A client with carpal tunnel syndrome was issued a prefabricated wrist cock-up splint by the OTR. During a follow-up session, the COTA is reviewing the wearing schedule and fit. The client reports that their fingers feel numb and tingly after wearing the splint for an hour.

What is the MOST appropriate immediate action for the COTA to take?

  1. Instruct the client to stop wearing the splint and schedule a re-evaluation with the OTR.
  2. Remove the splint, check for areas of excessive pressure, and adjust the straps for a looser fit. (correct answer)
  3. Advise the client that this is a normal sensation and to continue with the prescribed wearing schedule.
  4. Use a heat gun to modify the splint to relieve pressure on the median nerve.
Explanation: The COTA's first step should be to assess the immediate situation. Numbness and tingling suggest excessive pressure, likely from straps that are too tight or an improper fit. The COTA is qualified to check for pressure areas and make minor adjustments to straps. If this does not resolve the issue, then consulting the OTR is the next step. A is premature without first assessing the fit. C is incorrect as numbness and tingling are signs of a problem, not a normal sensation. D is outside the scope of practice for a COTA unless they have demonstrated service competency and it is part of the established plan.

Question 13

A COTA is working with a client who was recently fitted for a custom wrist cock-up splint by the OTR to manage wrist pain. After the first day of wearing the splint as scheduled, the client reports a significant INCREASE in sharp, localized pain at the wrist.

What is the COTA's MOST appropriate action?

  1. Reassure the client that some initial discomfort is normal and to continue wearing it.
  2. Advise the client to stop wearing the splint immediately and document the report for the OTR. (correct answer)
  3. Add extra padding to the splint in the area where the pain is located.
  4. Instruct the client to wear the splint for shorter periods until the pain subsides.
Explanation: A significant increase in pain is a red flag indicating the orthosis may be causing harm or is fitted improperly. The COTA's primary responsibility is to ensure client safety. The most appropriate action is to have the client discontinue use to prevent further injury and to communicate this adverse reaction to the supervising OTR, who can then re-evaluate the client and the orthosis. A, C, and D are all inappropriate actions as they could lead to further harm or do not address the root cause, which requires the clinical judgment of the OTR.

Question 14

An OTR directs a COTA to provide a client with a volar pan splint following a traumatic hand injury. The COTA brings the splint to the client, who refuses to put it on, stating, "That looks painful, I don't want to wear it."

What is the COTA's BEST therapeutic response?

  1. Acknowledge the client's concern, and explain in simple terms how the splint will protect their hand and help it heal. (correct answer)
  2. Document the client's refusal and move on to a different intervention activity.
  3. Insist that the client wear the splint as it is a critical part of the doctor's orders.
  4. Ask the OTR to come and talk to the client since they are refusing the COTA's instruction.
Explanation: This response demonstrates therapeutic use of self. The COTA first validates the client's feelings ('Acknowledge the client's concern') and then provides education on the splint's purpose and benefit. This client-centered approach builds rapport and addresses the client's fear, increasing the likelihood of compliance. B ignores the issue. C creates a power struggle. D is premature; the COTA should first use their skills to educate and encourage the client before escalating to the OTR.

Question 15

A client with mild wrist tendonitis was prescribed a prefabricated neoprene wrist support by the OTR. During a treatment session, the client asks the COTA, "My friend has a hard plastic splint that was molded to her arm. Would that be better for me?"

What is the BEST response for the COTA to provide?

  1. "Yes, a custom splint is always better, and I can ask the OTR to make one for you."
  2. "The type of support you have was chosen by the therapist to match your specific condition, which requires support but also allows for some movement." (correct answer)
  3. "It depends on your insurance coverage; custom splints are much more expensive."
  4. "They both do the same thing, so it doesn't really matter which one you use."
Explanation: This response educates the client about why their specific orthosis was chosen, reinforces the OTR's clinical reasoning, and stays within the COTA's scope of practice. The COTA should not make judgments about which orthosis is 'better' (A) or make definitive statements about cost and insurance (C). D is incorrect as different orthoses have very different purposes. The COTA's role is to implement the OTR's plan and help the client understand the rationale behind it.

Question 16

A COTA is reviewing the fit of a custom-fabricated wrist cock-up splint with a client. The OTR has asked the COTA to ensure the splint meets standard biomechanical principles.

Which of the following observations indicates a PROPER fit?

  1. The splint covers the entire length of the forearm, from elbow to fingertips.
  2. The splint allows for full, unrestricted flexion of the metacarpophalangeal (MCP) joints. (correct answer)
  3. The distal palmar crease is completely covered by the splint material.
  4. The wrist is positioned in 45 degrees of flexion to maximize functional use.
Explanation: A key principle of a wrist cock-up splint is that it should immobilize the wrist while allowing full motion of the digits. This means the distal palmar crease must be clear, allowing for full MCP joint flexion. A is incorrect; the splint should cover approximately two-thirds of the forearm length. C is incorrect as covering the distal palmar crease would block MCP flexion. D is incorrect as wrist cock-up splints typically position the wrist in extension (e.g., 15-30 degrees), not flexion.

Question 17

After a session where a COTA provides training on a new orthosis, the COTA must complete their documentation.

Which of the following is the MOST essential component to include in the COTA's documentation?

  1. The brand name and cost of the prefabricated orthosis.
  2. The client's ability to state the purpose of the orthosis and demonstrate proper application. (correct answer)
  3. The OTR's rationale for choosing this specific type of orthosis.
  4. A list of alternative orthoses that could have been used for the condition.
Explanation: Documentation should reflect the service provided and the client's response. For orthosis training, it is essential to document that the client understands the purpose, precautions, and wearing schedule, and has demonstrated the ability to don and doff it correctly. This shows that the training was effective and the client is safe to manage the orthosis. A, C, and D are not the primary responsibility of the COTA to document; the OTR's evaluation would contain the rationale (C), and cost (A) and alternatives (D) are not typically part of the daily treatment note.

Question 18

The OTR has provided a static progressive elbow splint to a client to increase extension following a contracture release surgery. After one week, the client reports that the splint no longer feels like it is providing a stretch.

What is the MOST appropriate action for the COTA to take?

  1. Instruct the client to wear the splint for longer periods of time.
  2. Adjust the angle of the splint to increase the extension stretch.
  3. Discontinue the splint and begin aggressive passive stretching.
  4. Inform the OTR that the client's range of motion has likely improved and the splint may need adjustment. (correct answer)
Explanation: The client's report indicates that the intervention is working and their range of motion has likely increased, meaning the splint is no longer at the end range. The COTA's role is to monitor progress and report changes to the OTR. The OTR is responsible for re-evaluating the client's ROM and making the necessary adjustments to the static progressive splint. A is incorrect because duration does not change the intensity of the stretch. B is a modification to the plan that must be done by the OTR. C is an unsafe change to the plan of care.

Question 19

A COTA is implementing an intervention plan for a client with a hand burn. The OTR has fabricated an antideformity intrinsic plus splint. The COTA observes that the client is consistently removing the splint due to discomfort.

What is the COTA's first step in addressing this situation?

  1. Tell the client that wearing the splint is mandatory for their recovery.
  2. Check the client's skin for any signs of pressure, irritation, or improper fit. (correct answer)
  3. Withhold pain medication until the client agrees to wear the splint.
  4. Immediately fabricate a new, more comfortable splint for the client.
Explanation: When a client is non-compliant due to discomfort, the first step is to investigate the cause. The COTA should perform a thorough check of the splint's fit and the underlying skin to rule out issues like excessive pressure, friction, or nerve compression. This information is crucial to report to the OTR, who can then determine if a modification is needed. A is not client-centered. C is unethical. D is outside the COTA's scope, as fabrication and design are the OTR's responsibility.

Question 20

A client with a radial nerve injury is being trained by a COTA to use a dynamic finger extension splint. The client asks, "Why do I need these rubber bands? They seem complicated."

How should the COTA BEST explain the purpose of the dynamic components?

  1. "They are designed to make your hand stronger by adding resistance."
  2. "They help lift your fingers up since the nerve injury makes it hard for your muscles to do that." (correct answer)
  3. "The OTR designed it this way, and we need to follow the plan exactly."
  4. "They provide a constant stretch to your finger joints to prevent them from getting stiff."
Explanation: The best explanation uses simple, client-centered language to describe the function of the orthosis. For a radial nerve injury, the dynamic component substitutes for weak or absent wrist and finger extensors. B accurately and simply describes this function. A is incorrect; the bands provide assistance, not resistance for strengthening. C is true but unhelpful and does not educate the client. D is incorrect; the primary purpose is to provide active extension, not a passive stretch.
