- According to the COTA's scope of practice, what is the MOST appropriate next step?
Answer: Document the new hazard and collaborate with the OTR to modify the plan.
The COTA's role is to implement the intervention plan and monitor the client's response. When a new problem or hazard is identified that may require a change to the plan (like the trip hazard), the COTA must report this information to the supervising OTR. The COTA and OTR then collaborate to determine the best course of action. Independently removing the rug without discussion, simply taping it (which may not solve the problem), or developing a new goal is outside the COTA's scope of practice.
- In a public library children's area, seating is limited to low beanbags and small stools.

- What is the IMMEDIATE ergonomic consequence of the client's feet not being supported?
Answer: Increased pressure on the popliteal area behind the knees.
When feet are unsupported, the weight of the legs pulls downward, causing the front edge of the chair to compress the soft tissues behind the knee (popliteal fossa). This can impede circulation and nerve function in the lower legs. While poor foot support can contribute to overall poor posture (and subsequently affect the back and neck), the most direct and immediate consequence is the pressure on the back of the legs.
- Which modification should the COTA install to BEST align with universal design principles for this client?
Answer: Replace all round knobs with lever-style handles.
Lever-style handles are a key feature of universal design because they can be operated without tight grasping or twisting, benefiting people with arthritis, limited hand strength, or even someone whose hands are full. This is a permanent modification that benefits all users. Rope pulls are an adaptation but less durable and universally usable. A jar opener/knob turner is an adaptive device, not a universal design modification to the environment. Instructing the client to ask for help promotes dependence, which is contrary to the goal of occupational therapy.

- What handling method should the COTA recommend to the client?
Answer: Slide the pot along the countertop to the edge nearest the table.
The principle of energy conservation and joint protection suggests using the easiest method possible. Sliding the heavy object eliminates the need to lift it, protecting the joints of the hands, wrists, elbows, and shoulders from strain. If lifting is unavoidable, using two hands with support from larger joints/surfaces (palms/forearms) would be the next best option. A pinch grip places maximal stress on small, vulnerable joints. Carrying with one hand is unstable and places asymmetrical strain on the body.

- Which of the following represents the BEST application of ergonomic principles for the client's hand tool?
Answer: Selecting a tool with a bent handle to allow for a neutral wrist posture.
A tool with a bent or pistol-grip handle is an ergonomic design that allows the user to perform a task while maintaining a straight, neutral wrist position. This reduces stress on the tendons and nerves passing through the carpal tunnel. Adding tape may increase the diameter but doesn't correct posture. Tight gloves can impede circulation and sensation. The size of the tool should be appropriate for the hand, not necessarily the smallest, to allow for a power grip rather than a pinch grip.
- Which instruction BEST reflects correct ergonomic lifting principles?
Answer: Get as close to the pallet as possible, bend your knees, and lift with your leg muscles.
Proper ergonomic lifting technique involves keeping the load close to the body, maintaining a neutral spine, and using the powerful leg muscles to lift, not the back muscles. Bending at the knees (squatting) rather than the waist is essential. Holding the box away from the body increases the lever arm and strain on the back. Lifting quickly and twisting are primary causes of back injuries.
- What is the FIRST ergonomic factor the COTA should address to ensure proper positioning for this client?
Answer: The clearance under the desk for the wheelchair's armrests and the client's knees.
Before any other ergonomic factors can be addressed, the client must be able to get close enough to the workstation. The first step is to ensure there is adequate knee and armrest clearance under the desk so the wheelchair can pull in completely. If the client cannot get close, their posture will be compromised regardless of monitor height, keyboard type, or lighting.

- Which feature would be the BEST example of universal design to include in the new bathroom?
Answer: A zero-threshold or 'curbless' shower.
A zero-threshold shower is a prime example of universal design. It eliminates barriers, making it accessible for a person using a walker or wheelchair, safer for an older adult with balance issues, and easy for a child to use.
