All questions

Question 1

A COTA is instructing a client on lower body dressing 3 weeks after a total hip arthroplasty (THA) with a posterior approach. The COTA observes the client bending forward at the waist to pull on their socks, causing their hip to flex beyond 90 degrees.

What is the COTA's BEST initial response?

  1. Provide a verbal cue to the client to lean back and bring the foot up towards the body. (correct answer)
  2. Document non-adherence to precautions and report it to the OTR at the end of the day.
  3. Allow the client to continue, as they are not reporting any pain.
  4. Tell the client to stop all dressing activities until the OTR can re-evaluate them.
Explanation: Breaking posterior THA precautions (no hip flexion beyond 90 degrees, no adduction, no internal rotation) increases the risk of hip dislocation. The COTA's primary role is to ensure safety by implementing the prescribed precautions. The best initial response is to provide an immediate verbal and/or physical cue to correct the client's posture and educate them on the proper technique. Documenting (B) is important but not the initial action. Allowing the client to continue (C) is unsafe, as damage can occur without pain. Stopping all activities (D) is overly cautious; the COTA can and should correct the technique as part of the intervention.

Question 2

A COTA is implementing an upper body endurance-building program with a client who has chronic obstructive pulmonary disease (COPD). The client is using a portable pulse oximeter as recommended. During a set of exercises using light weights, the client's oxygen saturation level drops from 94% to 88%.

Which action should the COTA take FIRST?

  1. Encourage the client to complete the set more quickly to finish the activity.
  2. Increase the client's supplemental oxygen flow rate.
  3. Stop the activity and instruct the client in pursed-lip breathing. (correct answer)
  4. Switch to an activity that uses heavier weights for fewer repetitions.
Explanation: An oxygen saturation level below 90% is a common precaution for terminating or modifying an activity for clients with COPD. The first and most appropriate action is to stop the exercise to prevent further desaturation and guide the client through recovery breathing techniques, such as pursed-lip breathing, to improve gas exchange. Rushing the client (A) or increasing resistance (D) would worsen the situation. A COTA is not authorized to independently adjust a client's oxygen flow rate (B); this requires a physician's order.

Question 3

A client is 3 days post-total knee arthroplasty (TKA). After a session of therapeutic exercises, including knee flexion and extension, the COTA observes that the client's knee has become significantly more swollen and the client reports a deep, throbbing ache.

Based on these observations, what is the COTA's BEST course of action?

  1. Encourage the client to walk around to reduce stiffness.
  2. Position the client with the leg elevated and apply a cold pack to the knee. (correct answer)
  3. Document the observation in the chart and wait for the next session to re-evaluate.
  4. Perform gentle massage on the knee to help dissipate the swelling.
Explanation: Increased swelling and throbbing pain after exercise are signs of an inflammatory response, indicating that the activity may have been too intensive. The immediate priority is to manage these symptoms. The standard protocol for post-exercise inflammation is RICE (Rest, Ice, Compression, Elevation). Therefore, elevating the leg and applying a cold pack is the most appropriate action. Ambulation (A) would likely increase pain and swelling. Simply documenting without taking action (C) ignores the client's immediate needs. Massage (D) may be contraindicated in an acute post-operative phase and could increase pain.

Question 4

A COTA is instructing a client with low back pain on how to perform an abdominal bridge. As the client lifts their hips off the mat, the COTA observes the client holding their breath and their face turning red.

What is the COTA's MOST important instruction for this client?

  1. Lift your hips higher to get a stronger contraction.
  2. Hold the position for at least 30 seconds.
  3. Exhale as you lift your hips and breathe normally. (correct answer)
  4. Place your hands under your lower back for support.
Explanation: The client is performing the Valsalva maneuver (forcefully exhaling against a closed glottis), which can cause a rapid increase in blood pressure and is contraindicated for many individuals, especially those with cardiovascular conditions. Proper breathing technique is a critical safety component of therapeutic exercise. The correct instruction is to cue the client to exhale during the concentric (exertion) phase of the movement and to maintain normal breathing. The other options relate to grading the exercise (A, B) or modifying the form (D), but addressing the unsafe breathing pattern is the priority.

Question 5

A client is participating in a work conditioning program after a distal radius fracture. The client has an additional diagnosis of non-insulin-dependent diabetes mellitus. During a circuit involving lifting and carrying weighted boxes, the client reports feeling shaky, dizzy, and sweaty.

What is the COTA's BEST initial response to this situation?

  1. Offer the client a diet soda and have them rest for 5 minutes.
  2. Stop the exercise, check the client's blood glucose level if possible, and provide juice or a glucose tab. (correct answer)
  3. Encourage the client to sit down and put their head between their knees.
  4. Instruct the client to take deep breaths and continue the activity at a slower pace.
Explanation: The client's symptoms (shakiness, dizziness, sweating) are classic signs of hypoglycemia (low blood sugar), which can be induced by exercise, especially in individuals with diabetes. The safest and most appropriate initial response is to stop the activity immediately to prevent further drops in blood sugar. If a glucometer is available, checking the level confirms the suspicion. The immediate treatment for hypoglycemia is to provide a fast-acting carbohydrate like juice or a glucose tablet. Diet soda (A) contains no sugar. Putting the head between the knees (C) is for vasovagal syncope, not hypoglycemia. Continuing the activity (D) is unsafe.

Question 6

A COTA is working with a client who has a full-thickness burn and a recent skin graft to the antecubital fossa. The intervention plan calls for AROM of the elbow.

When performing elbow flexion and extension exercises, which sign indicates to the COTA that the stretch is too forceful and should be eased?

  1. Slight reddening of the skin surrounding the graft.
  2. The client reporting a mild pulling sensation.
  3. Blanching or whitening of the skin graft. (correct answer)
  4. An increase in the client's heart rate.
Explanation: Blanching of a skin graft during movement indicates that the vascular supply to the graft is being compromised due to excessive tension. This is a critical sign to stop or reduce the stretch to avoid damaging the graft. A mild pulling sensation (B) is expected during stretching. Slight reddening (A) can be normal with activity. An increased heart rate (D) is a normal physiological response to exercise. The blanching is the specific contraindication for continuing the stretch at that intensity.

Question 7

A COTA is teaching a client with carpal tunnel syndrome a series of tendon and nerve gliding exercises. During the exercises, the client reports a significant increase in tingling and numbness in their thumb, index, and middle fingers.

What should be the COTA's initial response?

  1. Encourage the client to work through the tingling to achieve a better stretch.
  2. Immediately stop the exercise and reposition the client's wrist in a neutral position. (correct answer)
  3. Apply a hot pack to the client's wrist to reduce the symptoms.
  4. Have the client squeeze a stress ball to counteract the numbness.
Explanation: An increase in neurological symptoms (tingling, numbness) during nerve gliding exercises indicates that the nerve is being irritated or compressed. The correct response is to immediately cease the provocative movement and place the wrist in a neutral, resting position to relieve pressure on the median nerve. Pushing through the symptoms (A) could cause further nerve irritation. A hot pack (C) might increase inflammation. Squeezing a stress ball (D) involves wrist flexion and would likely worsen the compression.

Question 8

A COTA is working with a client who had open heart surgery 10 days ago and is under sternal precautions. The intervention plan includes practicing transfers from a low chair.

Which technique for rising from the chair must the COTA instruct the client to use to comply with precautions?

  1. Place both hands on the armrests and push up forcefully.
  2. Cross the arms over the chest and use leg strength to stand. (correct answer)
  3. Reach forward with one arm to pull on a walker to stand up.
  4. Place one hand on the armrest and the other on the knee to push up.
Explanation: Sternal precautions typically include no pushing, pulling, or lifting more than 5-10 pounds, and no asynchronous arm movements. Pushing up from a chair with the arms (A, D) violates these precautions and puts stress on the sternum. Reaching forward to pull (C) is also contraindicated. The safest method that adheres to precautions is to have the client cross their arms over their chest (or hug a pillow) and use the power from their legs to rise to a standing position, often by rocking forward to gain momentum.

Question 9

A client has an open reduction internal fixation (ORIF) of the humerus and is restricted to non-weight bearing (NWB) on the affected arm. The intervention plan includes core strengthening exercises in a quadruped (hands and knees) position.

How should the COTA modify this exercise to adhere to the client's precautions?

  1. Have the client perform the exercise while bearing weight on their forearms instead of their hands.
  2. Allow the client to bear a small amount of weight on the affected arm for stability.
  3. Have the client perform the exercise in a modified plank position on their elbows and toes.
  4. Consult with the OTR about an alternative exercise that does not involve the upper extremities. (correct answer)
Explanation: The quadruped position inherently requires weight-bearing through both upper extremities. Given the strict NWB precaution, this exercise is contraindicated as written. Any modification that still involves placing the arm on the support surface (A, C) violates the NWB status, even if on the forearm, as it still loads the humerus. Allowing some weight-bearing (B) is a direct violation of the precaution. The COTA's role is to recognize this conflict between the planned exercise and the client's precautions and consult with the supervising OTR to select a more appropriate core-strengthening exercise (e.g., a supine bridge or dead bug).

Question 10

A client with osteoarthritis (OA) of the hands is participating in an OT group focused on joint protection and exercise. The COTA is leading an activity involving theraputty.

Which instruction BEST reflects the therapeutic exercise precautions for this client?

  1. Squeeze the putty as hard as you can to maximize strength gains.
  2. Use only the tips of your fingers to pinch the putty to isolate smaller muscles.
  3. Perform repetitive gripping exercises for at least 15 minutes without a break.
  4. Avoid activities that cause joint deformity, such as forceful pinching. (correct answer)
Explanation: A key principle of exercise for OA is joint protection, which includes avoiding positions and forces that stress the joints and can lead to deformity (e.g., ulnar deviation). Forceful pinching with theraputty can put significant stress on the MCP and IP joints. Modifying the exercise to use a gross grasp or teaching the client to be mindful of joint alignment is crucial. Squeezing as hard as possible (A) or prolonged repetition (C) can cause joint pain and inflammation. While isolating small muscles (B) can be a goal, doing so with forceful pinching would be contraindicated.

Question 11

A client with a history of hypertension is performing light resistive exercises. The intervention plan notes to monitor blood pressure (BP) during the session. The client's resting BP was 130/85 mmHg. After two sets of exercises, the COTA re-measures and gets a reading of 170/105 mmHg.

According to general safety guidelines, what is the COTA's most appropriate action?

  1. Stop the resistive exercise and allow the client to rest before re-checking BP. (correct answer)
  2. Continue the exercise but reduce the resistance by half.
  3. Switch to an aerobic exercise like walking to help lower the client's BP.
  4. Tell the client this is a normal response and to finish the last set.
Explanation: A significant rise in blood pressure, particularly the diastolic pressure to over 100-110 mmHg, is a relative contraindication for continuing exercise. The safest course of action is to terminate the activity that is causing the BP elevation, allow the client to rest, and then re-assess their vital signs. Continuing the exercise, even at a lower intensity (B, C), is not advisable until the BP has returned to a safer level. Dismissing the reading as normal (D) is incorrect and could compromise client safety.

Question 12

A client is 2 weeks post-rotator cuff repair. The surgeon's protocol specifies passive range of motion (PROM) of the shoulder only. While the COTA is performing PROM for shoulder flexion, the client reports a sharp pain at 100 degrees of flexion.

How should the COTA modify the exercise?

  1. Push gently past the point of pain to increase the range of motion.
  2. Stop PROM at the point just before the client reports sharp pain. (correct answer)
  3. Switch to active-assistive range of motion to let the client control the movement.
  4. Apply a cold pack to the shoulder and then re-attempt the movement.
Explanation: The guiding principle for PROM, especially post-surgically, is to move the joint only to the point of tissue resistance or pain, but not beyond. Reporting sharp pain is an indication that structures are being overstressed. The correct modification is to stop the movement just shy of the painful arc. Pushing past the pain (A) could damage the surgical repair. Switching to active-assistive ROM (C) violates the surgeon's PROM-only protocol. While a cold pack (D) can manage pain, it does not address the immediate need to modify the exercise technique to prevent injury.

Question 13

A COTA is working with a client who sustained a CVA and has moderate spasticity in the left biceps. The goal is to increase elbow extension for dressing. The OTR's intervention plan includes therapeutic stretching.

Which technique should the COTA use to implement this intervention?

  1. Apply a quick, repetitive stretch to the biceps muscle.
  2. Ask the client to actively contract the triceps against the COTA's resistance.
  3. Provide a slow, prolonged stretch to the biceps while supporting the elbow. (correct answer)
  4. Use vibration on the biceps tendon to fatigue the muscle.
Explanation: Spasticity is velocity-dependent, meaning a quick stretch will trigger a hyperactive stretch reflex, increasing muscle tone. To inhibit spasticity and lengthen the muscle, the COTA should apply a slow, prolonged stretch. This technique minimizes the stretch reflex and allows the muscle to relax into a more elongated state. A quick stretch (A) would be counterproductive. While contracting the antagonist muscle (C) is a valid technique (reciprocal inhibition), a direct slow stretch is the fundamental approach. Vibration (D) can be used to inhibit or facilitate, but a slow stretch is the most common and direct technique for this goal.

Question 14

A COTA is implementing an exercise program for a client with active lymphedema of the right arm following breast cancer treatment. The plan includes light AROM exercises.

Which precaution is ESSENTIAL for the COTA to observe during this session?

  1. Ensure the client's arm is kept in a dependent position throughout the exercises.
  2. Monitor to ensure the client is wearing a properly fitted compression garment. (correct answer)
  3. Use heavy resistive exercises to create a muscle pumping effect.
  4. Check the client's blood pressure using the affected right arm.
Explanation: For clients with lymphedema, exercise should be performed while wearing a compression garment. The garment provides external pressure that prevents the accumulation of lymphatic fluid in the limb that can be caused by the increased blood flow from exercise. Keeping the arm dependent (A) would increase edema. Heavy resistance (C) is generally contraindicated as it can overwhelm the compromised lymphatic system. Blood pressure (D) should never be taken on the affected limb, as the cuff pressure can damage lymphatic vessels.

Question 15

A COTA is implementing a home exercise program with an 80-year-old client who has severe osteoporosis. The program includes strengthening exercises for the upper back and core to improve posture.

Which instruction is MOST critical for the COTA to provide to ensure the client's safety?

  1. Perform all exercises as quickly as possible to build muscle power.
  2. Avoid any exercises that involve forward bending or twisting of the spine. (correct answer)
  3. Use the heaviest weights the client can possibly lift for at least one repetition.
  4. Hold your breath during the hardest part of the exercise to stabilize your core.
Explanation: Osteoporosis makes bones fragile and susceptible to fracture. Spinal flexion (forward bending) and twisting motions place significant compressive forces on the vertebrae, which can lead to vertebral compression fractures. Therefore, the most critical safety precaution is to avoid these movements. Exercises should be slow and controlled (not A). High-load, low-rep lifting (C) is contraindicated. Holding one's breath (D), or the Valsalva maneuver, should be avoided as it can dangerously increase blood pressure.

Question 16

A client with rheumatoid arthritis (RA) is experiencing an acute flare-up with visible swelling and redness in the metacarpophalangeal (MCP) joints. The intervention plan, written prior to the flare-up, calls for theraputty exercises to improve grip strength.

Which course of action is MOST appropriate for the COTA to take?

  1. Proceed with the theraputty exercises but use a lighter resistance.
  2. Withhold resistive exercises and focus on gentle, pain-free active range of motion. (correct answer)
  3. Instruct the client to use a hot pack on their hands before starting the exercises.
  4. Discharge the client from therapy until the flare-up has subsided completely.
Explanation: During an acute inflammatory phase of RA, resistive exercises are contraindicated as they can exacerbate joint inflammation and pain. The most appropriate action is to modify the intervention to align with the client's current status. Focusing on gentle AROM within a pain-free range helps maintain joint mobility without causing further stress. Using lighter resistance (A) is still contraindicated. Applying heat (C) to an acutely inflamed joint can increase swelling and pain. Discharging the client (D) is not appropriate and is outside the COTA's scope of practice.

Question 17

A COTA is implementing a progressive resistive exercise (PRE) program for a client's quadriceps muscle. The protocol involves three sets of 10 repetitions. The client successfully completes the first two sets but can only perform 4 repetitions on the third set before reaching muscular failure.

How should the COTA proceed with the intervention?

  1. Assist the client in completing the last 6 repetitions passively.
  2. Insist that the client rest for 30 seconds and then complete the set.
  3. End the exercise for the day and document the number of repetitions completed. (correct answer)
  4. Decrease the weight and have the client start the third set over again.
Explanation: The principle of PREs is to exercise to the point of fatigue to stimulate muscle growth. When the client reaches muscular failure and cannot maintain proper form, the exercise should be terminated to prevent injury or the use of compensatory movements. The COTA's role is to accurately implement the protocol, monitor the client's response, and document the performance. Assisting passively (A) does not meet the goal of strengthening. Insisting the client continue (B) or starting over (D) can lead to over-fatigue or injury. The correct action is to stop and document the performance, which provides the OTR with the necessary data to adjust the resistance for the next session.

Question 18

A COTA is working with a 65-year-old client who is 4 days post-coronary artery bypass graft (CABG). The intervention plan includes gentle active range of motion (AROM) exercises for the upper extremities. During the session, while the client is performing shoulder flexion, they report feeling dizzy and lightheaded.

What is the COTA's MOST appropriate immediate action?

  1. Have the client perform pursed-lip breathing and continue the exercise.
  2. Stop the exercise, have the client rest, and check their vital signs. (correct answer)
  3. Tell the client that this is a normal response and encourage them to push through it.
  4. Immediately contact the supervising OTR to request a change in the intervention plan.
Explanation: The client's report of dizziness and lightheadedness during exercise is a potential sign of cardiopulmonary distress. The COTA's most appropriate immediate action is to stop the activity to prevent further complications, allow the client to rest, and assess their vital signs (e.g., blood pressure, heart rate, oxygen saturation). This response prioritizes client safety and gathers objective data to report to the OTR and medical team. Continuing the exercise (A) or encouraging the client to push through (C) is unsafe. While contacting the OTR is important (D), the immediate priority is to stop the activity and assess the client's physiological status.

Question 19

A COTA is working on PROM with a client who has a flaccid left upper extremity and shoulder subluxation following a recent CVA. The COTA is preparing to range the client's shoulder into flexion.

To implement this exercise safely, what must the COTA do PRIOR to moving the humerus?

  1. Ensure the scapula is gliding upwardly on the ribcage. (correct answer)
  2. Place a pillow under the client's elbow for support.
  3. Ask the client to try to assist with the movement.
  4. Position the client's wrist in full extension.
Explanation: Proper scapulohumeral rhythm is crucial for safe shoulder ROM. Without adequate upward rotation of the scapula, moving the humerus into flexion or abduction can cause impingement of the rotator cuff tendons and other soft tissues in the subacromial space. In a client with a flaccid arm, the COTA must manually ensure the scapula is mobile and properly positioned before and during humeral elevation. The other options are incorrect: a pillow (B) is for static positioning, asking for assistance (C) is AAROM not PROM, and wrist position (D) is not the primary safety concern for preventing shoulder impingement.

Question 20

A COTA is working in an outpatient clinic with a client who is consistently able to complete 3 sets of 15 repetitions of bicep curls with a 2-pound weight, reporting no fatigue or difficulty. The intervention plan goals include increasing upper body strength for home management tasks.

What is the MOST appropriate next step for the COTA to take?

  1. Increase the weight to 5 pounds without consulting the OTR.
  2. Discontinue the exercise as the client has clearly mastered it.
  3. Document the client's performance and report the progress to the supervising OTR. (correct answer)
  4. Have the client perform 5 sets of 15 repetitions with the same weight.
Explanation: The client has met the current challenge, indicating a need to grade up the activity. While the COTA can make minor adjustments, a significant change to the intervention plan (like upgrading the primary strengthening exercise) should be done in collaboration with the OTR. The COTA's role is to implement the plan, monitor progress, and provide feedback to the OTR. Therefore, the most appropriate action is to document the progress and discuss upgrading the program with the supervising OTR. Independently making a large jump in weight (A) may be unsafe or inappropriate. Discontinuing the exercise (B) is incorrect as the strength goal has not been fully met. Increasing sets (D) is one way to grade, but collaborating with the OTR on the overall progression is the best practice.
