All questions

Question 1

A COTA is educating a client on a home program for managing persistent edema in the left upper extremity following a mastectomy without complications.

Which instruction is MOST appropriate for the COTA to provide for managing edema when the client is resting in bed or on a sofa?

  1. Let your arm hang down beside you to promote circulation.
  2. Prop your arm on several pillows so that your hand is above your elbow, and your elbow is above your heart. (correct answer)
  3. Apply a heating pad to the arm to help dissipate the fluid.
  4. Wear a tight compression sleeve during the night to squeeze the fluid out.
Explanation: Elevation is a key principle of edema management. Positioning the limb above the level of the heart uses gravity to assist lymphatic and venous return, which helps to reduce edema. A dependent position (hanging down) would increase swelling.

Question 2

A COTA is working with a client on a desensitization program for a nerve injury of the hand. The client has successfully tolerated rubbing the hand with cotton balls and has progressed to tolerating terry cloth towels.

According to a typical desensitization hierarchy, what would be the NEXT texture for the COTA to introduce?

  1. Brushing with a scrub brush.
  2. Immersion in a container of dry rice. (correct answer)
  3. Rubbing with a piece of silk.
  4. Application of a cold pack.
Explanation: The progression of textures in desensitization moves from soft and smooth to more coarse and varied. After tolerating cotton (soft) and terry cloth (textured soft), immersion in a particle medium like dry rice or beans provides a greater level of varied tactile input and is a logical next step before progressing to very rough textures like a scrub brush.

Question 3

A COTA is preparing to apply a moist hot pack to a client's shoulder to address pain and stiffness, as outlined in the intervention plan. The client has intact sensation.

To ensure client safety and prevent burns, what is the MOST critical action for the COTA to take?

  1. Check that the hydrocollator water temperature is between 160-175°F (71-79°C).
  2. Position the client comfortably so they can relax during the application.
  3. Wrap the hot pack in the required number of towel layers, typically 6-8. (correct answer)
  4. Provide the client with a call bell and instruct them to report any discomfort.
Explanation: While all options are aspects of safe practice, the most direct and critical action to prevent a burn is ensuring the hot pack is wrapped in an adequate number of insulating layers. The standard is 6-8 layers of dry toweling between the pack and the client's skin. A hot pack cover often counts as 2-3 layers.

Question 4

A COTA is working with a client who has subacute pitting edema in the hand following a distal radius fracture. The intervention plan developed by the OTR includes retrograde massage.

What is the MOST appropriate technique for the COTA to use when performing the retrograde massage?

  1. Apply deep, circular friction motions starting from the wrist and moving toward the fingers.
  2. Use light, stroking motions beginning at the fingertips and moving toward the elbow. (correct answer)
  3. Apply static, deep pressure to the most edematous area on the dorsum of the hand.
  4. Use rapid, tapping motions with the fingertips across the entire edematous area.
Explanation: Retrograde massage is used to reduce edema by assisting the return of fluid from the extremity back to the lymphatic system and bloodstream. The correct technique involves light pressure applied in a distal-to-proximal direction, following the venous and lymphatic pathways.

Question 5

A COTA is implementing a scar management program for a client with a healed, hypertrophic burn scar on the forearm. The scar is sensitive and adhered to the underlying tissue.

When performing scar massage to increase tissue pliability, which technique should the COTA implement?

  1. Apply a thick layer of lotion and glide gently along the length of the scar.
  2. Use the pads of the fingers to apply firm pressure, moving the scar in circular and perpendicular directions relative to the underlying tissue. (correct answer)
  3. Stretch the scar to its maximum length and hold it for 60 seconds, repeating 3 times.
  4. Use a vibration tool on a high setting directly over the most sensitive part of the scar.
Explanation: The goal of scar massage for adhesions is to mobilize the scar tissue. This is achieved by applying firm pressure (enough to blanch the skin) without lotion, which would cause gliding on the surface. Moving the scar in circular and perpendicular directions helps to break up adhesions and soften the tissue.

Question 6

A COTA is working with a client with CRPS in the left upper extremity. The OTR's intervention plan includes initiating a stress loading program.

Which activity BEST represents the principles of a stress loading program?

  1. Gently rubbing the affected hand with progressively rougher textures.
  2. Engaging in guided imagery and deep breathing exercises.
  3. Scrubbing a tabletop with a brush, applying firm pressure through the affected arm. (correct answer)
  4. Performing passive range of motion exercises for the wrist and fingers.
Explanation: Stress loading is a key intervention for CRPS that involves two components: scrubbing (compression) and carrying (traction). These activities provide sustained, active compression and distraction to the joints and are thought to help normalize sensory input to the central nervous system. Scrubbing a surface is a classic example of the compression component.

Question 7

A client is concerned about a raised, dark keloid scar on their chest that formed after a minor surgery. The COTA is implementing the conservative scar management plan established by the OTR.

Which intervention is MOST appropriate and commonly used as a first-line conservative approach for managing a keloid scar?

  1. Vigorous deep friction massage to break down the scar tissue.
  2. Daily application of a silicone gel sheet under light pressure. (correct answer)
  3. Application of ultrasound to the scar for 5-8 minutes.
  4. Aggressive stretching exercises to flatten the scar.
Explanation: Silicone gel sheets are a widely used, evidence-based, non-invasive intervention for hypertrophic and keloid scars. They work by hydrating the scar tissue and are thought to regulate collagen synthesis, which can help soften, flatten, and reduce the discoloration of the scar. Vigorous massage can sometimes worsen keloid scars.

Question 8

A COTA is about to begin an edema management session with a new client who has significant swelling in their right arm. Upon reviewing the chart, the COTA notes a history of congestive heart failure (CHF) and kidney disease.

What is the COTA's MOST important initial action?

  1. Proceed with gentle retrograde massage, monitoring for signs of dizziness.
  2. Measure the circumference of the arm in several places to establish a baseline.
  3. Consult with the supervising OTR to confirm medical clearance for edema mobilization. (correct answer)
  4. Elevate the client's arm and instruct them in active range of motion exercises.
Explanation: Systemic conditions like CHF and kidney disease are significant precautions for edema management. Mobilizing a large volume of fluid from the extremities can increase the load on the heart and circulatory system, potentially exacerbating these conditions. It is critical for the COTA to verify with the OTR that this intervention is medically cleared and safe for the client before proceeding.

Question 9

A COTA is teaching a client how to perform scar massage at home for a healed incision on their hand. The client is unsure how much pressure to use.

Which instruction BEST describes the appropriate amount of pressure for effective scar massage?

  1. Press just enough so that you can feel the warmth from your finger.
  2. Use enough pressure to make the scar and surrounding skin turn white or blanch. (correct answer)
  3. Apply very light pressure, as if you were spreading butter on soft bread.
  4. Press until you feel a moderate level of pain, then hold the pressure.
Explanation: To effectively mobilize a scar and break down adhesions, the pressure must be firm enough to move the scar tissue over the underlying structures. A visual cue for this appropriate level of pressure is the temporary blanching (whitening) of the tissue, which indicates that blood flow has been momentarily occluded by the pressure.

Question 10

A client is experiencing acute inflammation and pain in the lateral epicondyle area. The OTR has included cryotherapy in the intervention plan to be implemented by the COTA following activity.

What is the MOST appropriate method for the COTA to apply cryotherapy to this localized area?

  1. A 20-minute application of a gel cold pack wrapped in a dry towel.
  2. Immersion of the entire forearm and elbow in an ice water bath.
  3. Performing an ice massage directly over the painful area for 5-8 minutes, until numbness is achieved. (correct answer)
  4. A 30-minute application of a vapo-coolant spray over the area.
Explanation: For small, localized areas of pain and inflammation like lateral epicondylitis, ice massage is a very effective and efficient method of cryotherapy. It provides intense cooling to a specific tissue and is applied until the client experiences the stages of cold, burning, aching, and finally numbness (CBAN), which typically takes 5-10 minutes.

Question 11

An OTR who is a certified lymphedema therapist (CLT) has evaluated a client and developed a plan for Complete Decongestive Therapy (CDT). The OTR has delegated the task of bandaging to the COTA after providing specific training and verifying competency.

Which action is within the COTA's scope of practice when implementing this part of the plan?

  1. Performing manual lymphatic drainage (MLD) on the client.
  2. Independently determining the appropriate number of bandage layers.
  3. Applying the multi-layer, short-stretch compression bandages exactly as instructed by the OTR. (correct answer)
  4. Re-evaluating the client's limb volume to decide when to discontinue bandaging.
Explanation: The COTA's role is to implement the intervention plan developed by the OTR. After demonstrating service competency, it is appropriate for the COTA to apply the prescribed bandaging. MLD requires advanced certification, and designing or modifying the plan (determining layers, deciding on discontinuation) are evaluative and planning tasks that fall under the OTR's responsibilities.

Question 12

A COTA is initiating mirror therapy with a client who has phantom limb pain following a right below-elbow amputation. The client is seated in front of the mirror box.

What is the PRIMARY instruction the COTA should give the client to begin the therapy?

  1. Place your right residual limb in the box and focus on its appearance.
  2. Close your eyes and imagine your right hand is moving without pain.
  3. Place your left hand in the box, and watch its reflection as you perform slow movements. (correct answer)
  4. Try to touch the reflection of your left hand with your right residual limb.
Explanation: The fundamental principle of mirror therapy is to create a visual illusion. The client places their intact limb (left hand) inside the box and views its reflection in the mirror. This reflection appears to be their amputated limb (right hand). By moving the intact limb, they create the visual perception of their phantom limb moving normally and without pain, which can help reorganize cortical pathways and reduce pain signals.

Question 13

A client sustained a full-thickness burn to the dorsum of the hand and is at risk for a claw hand deformity (MCP hyperextension and IP flexion). The intervention plan includes using a compression glove and silicone gel sheeting for scar management.

What is the BEST way for the COTA to integrate these two interventions?

  1. Cut the gel sheet to the size of the scar and place it under the compression glove. (correct answer)
  2. Alternate wearing the gel sheet for 4 hours and the glove for 4 hours.
  3. Apply the gel sheet over the top of the compression glove to hold it in place.
  4. Use the gel sheet during the day and the compression glove only at night.
Explanation: For optimal effectiveness, the silicone gel sheet must be in direct contact with the scar tissue. Wearing a compression glove over the sheeting serves two purposes: it holds the sheet securely in place and provides therapeutic pressure to the scar, which helps to flatten and soften it while also managing edema.

Question 14

A COTA is using a Transcutaneous Electrical Nerve Stimulation (TENS) unit on a client for chronic back pain, following the parameters established by the OTR. After several sessions, the client reports that the TENS is no longer providing the same level of pain relief.

What is the COTA's BEST course of action in response to the client's report?

  1. Independently increase the pulse width and intensity settings on the unit.
  2. Change the electrode placement based on the COTA's own clinical judgment.
  3. Discontinue TENS and use a different modality, such as a hot pack.
  4. Document the client's report and discuss it with the supervising OTR before the next session. (correct answer)
Explanation: The client may be experiencing accommodation to the stimulus. However, modifying the parameters or modality of a physical agent modality (PAM) is outside the COTA's scope of practice. The COTA's role is to implement the established plan, monitor the client's response, and report outcomes and changes to the OTR. The OTR will then determine if the plan needs modification.

Question 15

A client is 8 weeks post-flexor tendon repair surgery and has a well-healed but adherent scar on the volar surface of their wrist. The OTR has directed the COTA to implement scar management interventions.

Which intervention is MOST appropriate for the COTA to implement to address the scar adherence?

  1. Applying an elastomer mold secured with a compression wrap. (correct answer)
  2. Using cryotherapy over the scar for 15 minutes before activity.
  3. Instructing the client to avoid moving the wrist to prevent scar irritation.
  4. Beginning aggressive, painful stretching of the scar tissue.
Explanation: At this stage of healing, an elastomer mold combined with compression is an effective intervention. The elastomer conforms to the scar and, under pressure, helps to soften the scar tissue and reduce adhesions, improving tissue mobility.

Question 16

A COTA is preparing to apply a short-stretch compression bandage to a client's edematous forearm and hand.

Which guiding principle is ESSENTIAL for the COTA to follow during the application?

  1. Wrap the bandage in a proximal-to-distal direction.
  2. Apply the greatest amount of pressure distally, decreasing the pressure proximally. (correct answer)
  3. Ensure the tension of the wrap is equal throughout the entire limb.
  4. Leave the wrap on for 24 hours before removing it for skin inspection.
Explanation: To effectively move fluid out of an extremity, compression bandages must be applied with a pressure gradient. The pressure should be highest at the most distal point (e.g., hand/wrist) and gradually decrease as the wrap moves up the limb proximally (e.g., toward the elbow). This gradient prevents a tourniquet effect and promotes fluid return.

Question 17

A client with complex regional pain syndrome (CRPS) of the hand is starting a desensitization program due to hypersensitivity. The client finds even light touch to be painful.

What is the FIRST type of stimuli the COTA should introduce according to a standard desensitization hierarchy?

  1. A piece of rough Velcro.
  2. A bowl of lukewarm, dry rice.
  3. A soft piece of cotton or fleece. (correct answer)
  4. A vibrating massager on a low setting.
Explanation: Desensitization programs are graded and proceed from the least noxious to more noxious stimuli. The hierarchy typically begins with very soft, light textures like cotton, silk, or fleece, before progressing to rougher textures like rice/beans, and finally to textures like Velcro or sandpaper.

Question 18

A COTA is implementing a desensitization protocol for a client with hypersensitivity on the tip of their thumb following a nerve laceration. The client is unable to tolerate even the softest texture (cotton) directly on the most sensitive point.

What is the BEST way for the COTA to grade this activity?

  1. Insist the client tolerate the cotton for at least 30 seconds to overcome the sensitivity.
  2. Apply the cotton to the area just surrounding the hypersensitive point. (correct answer)
  3. Immediately switch to a rougher texture to provide a stronger stimulus.
  4. Have the client wear a protective finger cot over the thumb.
Explanation: Grading is essential in desensitization. If direct application is intolerable, a standard grading technique is to apply the stimulus to the less sensitive areas surrounding the most hypersensitive point. As tolerance improves, the stimulus can be moved progressively closer to the target area.

Question 19

A COTA is instructed to administer contrast baths to a client with a chronic hand injury to address persistent, mild edema and stiffness.

Which procedure correctly describes the standard protocol for administering a contrast bath for this condition?

  1. Begin in cold water for 10 minutes, followed by warm water for 1 minute, and repeat.
  2. Alternate every 5 minutes between warm and cold water for 20 minutes, ending in cold.
  3. Begin in warm water for 3-4 minutes, then cold water for 1 minute; repeat this cycle for 20-30 minutes, ending in warm water. (correct answer)
  4. Immerse the hand only in warm water for 15 minutes, then only in cold water for 15 minutes.
Explanation: The standard protocol for contrast baths aims to create a vascular pumping action. This typically involves a longer duration in warm water (e.g., 3-4 minutes) to promote vasodilation, followed by a shorter duration in cold water (e.g., 1 minute) to promote vasoconstriction. For chronic conditions where the goal is to decrease stiffness and increase circulation, the sequence typically starts and ends with warm water.

Question 20

An elderly client with osteoarthritis in their hands reports severe morning stiffness and pain, which limits their ability to perform grooming tasks. The COTA is preparing the client for an ADL session.

Which preparatory method is MOST suitable for the COTA to use to address the client's symptoms before the activity?

  1. Immersion of the hands in a paraffin bath. (correct answer)
  2. Application of cold packs to both hands for 15 minutes.
  3. Squeezing therapy putty for 5 minutes.
  4. Performing PROM exercises on all finger joints.
Explanation: Paraffin wax provides moist, circumferential heat to the hands, which is highly effective for reducing the pain and stiffness associated with osteoarthritis. Using it as a preparatory activity can improve joint mobility and comfort, enabling greater participation in subsequent functional tasks.
