Progressing Regressing InterventionsQuestion 1 of 20

A 68-year-old male is in phase II cardiac rehabilitation 8 weeks after a coronary artery bypass graft (CABG). During a supervised session, he walks on a treadmill at 2.5 mph with a 2% grade for 15 minutes. His heart rate is 115 bpm, blood pressure is 130/80 mmHg, and RPE is 12/20. He denies angina or dyspnea. However, the supervising therapist notes a new S3 heart sound during auscultation post-exercise and 2+ bilateral pitting edema that was not present last session. The patient's weight is up 4 lbs (1.8 kg) from the previous visit.

Based on these findings, what is the MOST appropriate action for the physical therapist to take regarding the patient's exercise program?

Progress the treadmill duration by 5 minutes at the next session, as the patient remained asymptomatic with a heart rate within the target range.

Maintain the current exercise parameters for one more week to monitor the patient's response before progressing intensity or duration.

Regress the exercise to seated activities, hold the current session, and contact the referring cardiologist regarding signs of potential heart failure.

Discontinue aerobic exercise and focus on flexibility and patient education regarding diet and sodium intake to manage the new edema.

All questions

Question 1

Based on these findings, what is the MOST appropriate action for the physical therapist to take regarding the patient's exercise program?

Progress the treadmill duration by 5 minutes at the next session, as the patient remained asymptomatic with a heart rate within the target range.
Maintain the current exercise parameters for one more week to monitor the patient's response before progressing intensity or duration.
Regress the exercise to seated activities, hold the current session, and contact the referring cardiologist regarding signs of potential heart failure. (correct answer)
Discontinue aerobic exercise and focus on flexibility and patient education regarding diet and sodium intake to manage the new edema.

Explanation: The correct answer is C. The combination of a new S3 heart sound, worsening bilateral pitting edema, and sudden weight gain are hallmark signs of decompensating congestive heart failure. This is a significant change in medical status that requires immediate regression of the intervention and communication with the physician. Continuing or maintaining aerobic exercise would be unsafe. A is incorrect because progressing the exercise ignores the new, critical clinical signs of cardiac decompensation. The absence of angina does not rule out a serious underlying issue. B is incorrect because simply maintaining the parameters is too passive. The signs indicate a potentially acute medical problem that requires more than just monitoring; it requires medical consultation. D is incorrect because while education is important, discontinuing all aerobic exercise and focusing only on flexibility is not the most critical action. The priority is to stop the current activity and ensure medical follow-up for the signs of heart failure.

Question 2

A 20-year-old soccer player is 6 months post-anterior cruciate ligament reconstruction using a patellar tendon autograft. The patient has full range of motion, no effusion, and quadriceps strength is 95% of the contralateral limb. The patient successfully completes the single leg hop for distance, achieving 92% of the contralateral side. However, during a triple hop test, the patient demonstrates a 25% limb symmetry index and exhibits noticeable knee valgus during landing.

Which modification to the plan of care is MOST appropriate for this patient?

Initiate a return-to-running program on a treadmill and progress to cutting drills as tolerated by the patient.
Regress to non-weight bearing quadriceps strengthening to improve the limb symmetry index on strength testing to over 98%.
Continue with the current hop testing to improve performance and confidence before initiating sport-specific drills.
Hold progression to agility drills and incorporate neuromuscular re-education focused on landing mechanics and gluteal activation. (correct answer)

Explanation: The correct answer is D. The patient demonstrates poor quality of movement (knee valgus) and poor performance on a dynamic, multi-hop test, despite meeting criteria on a single hop test and strength testing. This indicates a deficit in neuromuscular control and motor programming under load, which significantly increases the risk of re-injury. The priority is to address these qualitative deficits before progressing to higher-level activities. A is incorrect because progressing to running and cutting is unsafe given the demonstrated dynamic knee valgus. This poor landing strategy must be corrected first. B is incorrect because regressing to non-weight bearing exercises is unnecessary. The patient's quadriceps strength is already adequate ( >90% LSI), and the deficit is in dynamic motor control, not isolated strength. C is incorrect because simply repeating the test that reveals the deficit without specifically training the underlying components (neuromuscular control) is inefficient and potentially unsafe.

Question 3

A 45-year-old patient is in the recovery phase of Guillain-Barré syndrome (GBS), 12 weeks after onset. Manual muscle testing shows grade 4-/5 strength in the bilateral tibialis anterior. The physical therapist prescribes strengthening exercises consisting of 3 sets of 10 repetitions of active ankle dorsiflexion against a light resistance band. The patient completes the exercises but reports profound muscle soreness and demonstrates a decrease in functional strength (increased foot drop during gait) the following day.

What is the MOST appropriate modification to the intervention plan?

Increase the resistance of the band to provide a greater stimulus for strengthening, as the initial resistance was inadequate.
Discontinue resistance exercises and switch to passive range of motion only until the patient's soreness fully resolves.
Decrease the number of repetitions and/or sets and monitor for post-exercise fatigue and strength loss before progressing. (correct answer)
Add functional electrical stimulation to the tibialis anterior during gait training to compensate for the observed foot drop.

Explanation: The correct answer is C. The patient is exhibiting signs of overwork weakness, a phenomenon common in demyelinating conditions like GBS. Exercising muscles to the point of exhaustion can lead to a paradoxical decrease in strength. The appropriate response is to regress the exercise volume (reps/sets) and intensity, ensuring the patient does not experience a decline in function after a session. Progression should be much more gradual and based on tolerance. A is incorrect because increasing resistance would exacerbate the overwork weakness and is contraindicated. B is incorrect because it is an overly conservative regression. The patient can still benefit from active exercise, but the dosage must be carefully managed. Discontinuing all strengthening would be detrimental to recovery. D is incorrect because while FES could be a useful adjunct, it does not address the primary problem, which is the inappropriate prescription of the strengthening exercise. The exercise itself must be modified first.

Question 4

An 85-year-old female with moderate Alzheimer's disease is 3 weeks post-open reduction internal fixation of a right hip fracture. She is weight-bearing as tolerated. During gait training with a standard walker, she consistently forgets sequencing cues and becomes highly agitated, yelling and refusing to advance the walker. This behavior occurs after approximately 20 feet of ambulation. Her vital signs remain stable.

What is the MOST appropriate modification for the current physical therapy session?

Discontinue gait training and document the patient as non-compliant and having a poor rehabilitation potential.
Continue with gait training but use a firm tone of voice and physical assistance to ensure the patient ambulates the planned distance.
Switch to a rolling walker to reduce the cognitive load of sequencing and attempt shorter, more frequent bouts of ambulation. (correct answer)
Regress to bedside therapeutic exercises, focusing on quadriceps and gluteal sets to improve strength before re-attempting gait.

Explanation: The correct answer is C. The patient's agitation is likely due to cognitive overload and frustration, not non-compliance. A standard walker requires a complex sequence (walker, bad leg, good leg) that can be difficult for a person with dementia. A rolling walker simplifies the task by allowing a more continuous movement pattern. Shorter, more frequent bouts can also help manage fatigue and attention deficits, making the session more successful and less stressful for the patient. A is incorrect because labeling the patient as non-compliant is inappropriate. The behavior is a symptom of her cognitive impairment, and the therapist's role is to adapt the intervention to the patient. B is incorrect because forcing the patient to continue will likely increase agitation and may be considered abusive. It does not address the underlying cause of the difficulty. D is incorrect because while strengthening is important, the primary barrier to ambulation in this scenario is cognitive, not physical. Regressing to basic exercises fails to address the functional goal using appropriate adaptive strategies.

Question 5

A patient with a chronic right unilateral vestibular hypofunction has been performing gaze stability exercises (VOR x1 viewing) for 3 weeks. They are now able to perform the exercise for 1 minute at a speed of 120 beats per minute while seated, reporting only 2/10 dizziness and demonstrating no loss of visual focus on the target. The patient's goal is to walk in a crowded mall without dizziness.

Which of the following represents the MOST appropriate progression of this patient's exercise program?

Increase the duration of the seated VOR x1 exercise to 3 minutes to improve the patient's endurance.
Progress the patient to performing the VOR x1 exercise while standing on a firm surface at the same speed. (correct answer)
Discontinue the VOR x1 exercise and begin habituation exercises involving repeated head movements into provoking positions.
Add a cognitive dual-task, such as reciting the alphabet backwards, while performing the seated VOR x1 exercise.

Explanation: The correct answer is B. According to the principles of vestibular rehabilitation, exercises should be progressed by making them more challenging and functionally relevant. The patient has mastered the exercise in a stable seated position. The next logical step is to challenge the postural control system by having the patient perform the same exercise in standing. This moves them closer to the functional goal of walking. A is incorrect because increasing duration from 1 to 3 minutes provides minimal additional benefit for VOR adaptation once a therapeutic dose is achieved (typically 1-2 minutes). The priority is to increase the challenge, not just the duration. C is incorrect because habituation exercises are for motion sensitivity (e.g., from BPPV), whereas this patient's diagnosis is a hypofunction, which is best treated with adaptation exercises like VOR training. Discontinuing the primary treatment would be inappropriate. D is incorrect because adding a cognitive task is a valid progression, but it is generally considered a higher-level challenge than changing the postural demand from sitting to standing. The postural challenge is a more direct step toward the goal of walking.

Question 6

A 48-year-old office worker is being treated for subacromial pain syndrome. After 4 weeks of treatment focusing on activity modification and pain-free range of motion, the patient is now able to perform 3 sets of 15 repetitions of shoulder external rotation at 0° abduction and scaption to 90° with a 2-lb (0.9 kg) weight without pain. The patient's goal is to return to recreational volleyball.

What is the MOST appropriate progression of the therapeutic exercise program?

Increase the weight for scaption and external rotation to 5 lbs (2.3 kg) to maximize rotator cuff strength.
Incorporate exercises that challenge the rotator cuff and scapular stabilizers in higher ranges of abduction and external rotation. (correct answer)
Discontinue isolated strengthening and begin a program of generalized upper body stretching to improve flexibility.
Add ultrasound and iontophoresis to the shoulder to ensure all inflammation is resolved before progressing further.

Explanation: The correct answer is B. The patient has mastered basic, isolated strengthening in a pain-free range. To meet the demands of an overhead sport like volleyball, the exercises must be progressed to challenge the muscles in positions that are more functionally relevant. This includes strengthening in positions of greater shoulder abduction and external rotation, which mimic the cocking phase of throwing or spiking. This progression respects the tissue healing while advancing toward the patient's specific functional goals. A is incorrect because simply increasing the weight in the same, limited range of motion does not prepare the shoulder for the demands of overhead activity. The progression should involve movement patterns before large increases in load. C is incorrect because discontinuing strengthening is premature. While flexibility is important, the foundation of rehabilitation for subacromial pain is restoring dynamic muscular control of the shoulder complex. D is incorrect because progressing to passive modalities is a regression in the plan of care. The patient has moved beyond the acute phase and requires active, progressive loading, not passive treatments.

Question 7

A 67-year-old patient with idiopathic Parkinson's Disease (Hoehn & Yahr stage 3) has completed 3 weeks of an intensive, amplitude-based training program (e.g., LSVT BIG). The patient shows significant improvement in movement amplitude during structured tasks within the clinic (e.g., large steps, long reaches). However, the patient's wife reports he still frequently experiences freezing of gait (FOG) when trying to turn around in the kitchen or walk through a doorway at home.

Which modification to the plan of care would MOST effectively address the patient's persistent freezing of gait?

Increase the intensity and repetition of the current amplitude-based exercises to promote better carryover.
Discontinue amplitude-based training and switch to a program focused on muscular strengthening and endurance.
Incorporate external cueing strategies, such as visual targets on the floor or a rhythmic auditory beat, during functional mobility tasks. (correct answer)
Instruct the patient to focus on a cognitive task, such as counting backwards, while walking to improve automaticity of movement.

Explanation: The correct answer is C. The patient has improved with generalized amplitude training but struggles to apply it in specific contexts that trigger FOG. Freezing is often related to a failure of internal rhythm generation. External cues (visual or auditory) provide a bypass for this faulty internal mechanism, allowing the patient to initiate and maintain movement through challenging situations. This is a standard, evidence-based progression to address FOG once basic amplitude is established. A is incorrect because simply doing more of the same exercise is unlikely to address the context-specific problem of FOG. The strategy needs to be adapted, not just intensified. B is incorrect because amplitude-based training is highly effective for the bradykinesia and hypokinesia of Parkinson's. Discontinuing it would be a mistake. The issue is not a lack of strength but a problem with motor initiation. D is incorrect because adding a cognitive dual-task often worsens FOG in patients with Parkinson's Disease, as it diverts attentional resources away from the motor task. This would be counterproductive.

Question 8

A 65-year-old patient is 4 days post-operative from a right total knee arthroplasty (TKA). The patient's current active range of motion is 5° to 85° of flexion. The patient is able to perform a straight leg raise without an extension lag and can perform 3 sets of 10 quadriceps sets with a good contraction. The patient is weight-bearing as tolerated and ambulates 50 feet with a standard walker and moderate assistance.

Which of the following interventions is the MOST appropriate to add to the plan of care at this time?

Initiate mini-squats from 0° to 45° of knee flexion while using the parallel bars for support. (correct answer)
Begin using a continuous passive motion (CPM) machine for 6 hours per day to increase flexion to 110°.
Focus on increasing the number of quadriceps sets to 5 sets of 20 to maximize muscle hypertrophy.
Add passive knee extension stretching with an overpressure cuff weight to achieve full extension.

Explanation: The correct answer is A. The patient has achieved key early-stage goals: good quadriceps activation (no extension lag) and basic mobility. The next step is to progress from non-weight-bearing or minimal weight-bearing exercises to early closed-chain strengthening. Mini-squats are an excellent way to co-contract the quadriceps and hamstrings, promote functional strengthening, and improve neuromuscular control in a safe, controlled manner. B is incorrect because the evidence for the effectiveness of CPM machines is weak, and they are used less frequently. Furthermore, the patient is already at 85° of active flexion, and active motion is preferred over passive motion. C is incorrect because while quad strength is important, the focus should shift from isolated isometrics (quad sets) to more functional, weight-bearing exercises. Simply increasing the volume of quad sets is an inefficient use of time. D is incorrect because the patient has a flexion contracture of 5°, not an extension lag from quad weakness. While achieving full extension is critical, adding a passive stretch with a cuff weight is an aggressive intervention that could cause excessive stress on the incision and anterior knee structures this early post-op. Active extension and gentle manual stretching are preferred.

Question 9

A physical therapist is treating a 38-year-old patient with lateral epicondylalgia. The therapist implements a plan of care based on a well-validated clinical prediction rule (CPR) that includes specific manual therapy techniques and exercises. After 4 sessions, the patient's score on the Patient-Rated Tennis Elbow Evaluation (PRTEE) has improved from 70/100 to 62/100. The patient reports they still cannot open a jar or use a computer mouse without significant pain.

Based on the patient's response, what is the MOST appropriate action for the physical therapist?

Discontinue the CPR-based approach and switch to a different treatment paradigm, such as one focused on modalities.
Continue the current plan of care for another 4 sessions, as some improvement has been noted and CPRs take time to work.
Refer the patient back to their primary care physician for a corticosteroid injection to manage the persistent pain.
Re-evaluate the patient for contributing factors from the cervical spine and add interventions directed at this region if indicated. (correct answer)

Explanation: When treating lateral epicondylalgia that isn't responding optimally to evidence-based interventions, you need to consider the broader kinetic chain and potential contributing factors. While clinical prediction rules provide excellent starting points, they don't account for every patient's unique presentation. The correct answer is D because cervical spine dysfunction is a well-documented contributing factor to lateral epicondylalgia. The cervical spine can refer pain to the lateral elbow region, and cervical joint restrictions or nerve sensitization can perpetuate symptoms even when local elbow treatments are appropriate. Since this patient shows minimal improvement despite following a validated CPR, expanding the examination to include the cervical spine is the logical next step before abandoning the current approach entirely. A is premature because modalities are generally less effective than manual therapy and exercise for lateral epicondylalgia, and switching paradigms after only 4 sessions without exploring other contributing factors isn't warranted. B ignores the patient's functional limitations - while the PRTEE score improved slightly, the inability to perform basic tasks like opening jars suggests the current approach alone is insufficient. C immediately refers for injections without exhausting conservative options, which contradicts best practice guidelines that emphasize progressive conservative care. NPTE Strategy: When evidence-based treatments show limited progress, always consider proximal and distal contributing factors before abandoning the approach. The exam frequently tests your ability to think beyond the primary diagnosis and consider the kinetic chain, especially for conditions like lateral epicondylalgia where cervical involvement is common.

Question 10

A physical therapist is working with a 78-year-old patient in an acute care setting who is 2 days post-colectomy. The patient has a patient-controlled analgesia (PCA) pump with morphine for pain management. During an initial attempt to ambulate from the bed to a chair, the patient becomes increasingly lethargic and their speech becomes slurred. The therapist notes the patient's respiratory rate has dropped from a baseline of 16 breaths per minute to 8 breaths per minute.

What is the MOST appropriate immediate action for the physical therapist?

Discontinue the session, ensure the patient is in a safe position, and immediately activate the facility's emergency response team. (correct answer)
Administer a sternal rub to arouse the patient and continue with a transfer to the chair with maximum assistance.
Return the patient to bed, elevate the head of the bed, and document the adverse reaction to activity.
Check the PCA pump settings and instruct the patient to press the button less frequently to avoid over-sedation.

Explanation: When you encounter a patient showing signs of respiratory depression in an acute care setting, you're dealing with a potential medical emergency that requires immediate intervention. This scenario tests your ability to recognize opioid-induced respiratory depression and prioritize patient safety over continuing therapy. The combination of lethargy, slurred speech, and most critically, a respiratory rate dropping from 16 to 8 breaths per minute strongly indicates opioid overdose from the morphine PCA pump. Respiratory rates below 10 breaths per minute signal severe respiratory depression that can rapidly progress to respiratory arrest and death. Option A is correct because it follows the proper emergency response protocol: ensure immediate safety, position the patient appropriately, and activate emergency services. The medical team can administer naloxone (Narcan) to reverse the opioid effects and provide advanced life support if needed. Option B is dangerous because a sternal rub won't address the underlying respiratory depression, and continuing the transfer could worsen the patient's condition or cause injury if they lose consciousness. Option C fails to recognize the severity of the situation—this isn't just an adverse reaction to activity but a medical emergency requiring immediate intervention beyond basic positioning. Option D is inappropriate because as a physical therapist, you shouldn't adjust medical equipment settings, and instructing a lethargic, potentially overdosed patient about PCA usage is ineffective and delays critical care. Remember: respiratory rates below 10 breaths per minute in patients on opioids always warrant immediate emergency response. Patient safety trumps continuing any therapy session.

Question 11

A patient with Stage 2 lymphedema of the left upper extremity following a mastectomy is undergoing Phase I of complete decongestive therapy (CDT). After 10 treatment sessions over 2 weeks involving manual lymphatic drainage (MLD) and multi-layered short-stretch compression bandaging, her circumferential measurements have decreased by an average of 18%, and the limb tissue is now soft with no pitting. The patient has been instructed in and is independent with her self-care program.

What is the MOST appropriate next step in the management of this patient?

Discontinue all treatment as the reduction has plateaued and the limb is soft, indicating maximum benefit has been achieved.
Continue with daily MLD and multi-layered bandaging for another 2 weeks to achieve further reduction in limb volume.
Measure the patient for a daytime compression garment and instruct her in a home program of self-MLD and nighttime bandaging. (correct answer)
Transition the patient to using a pneumatic compression pump at home for 2 hours per day as a replacement for MLD and bandaging.

Explanation: The correct answer is C. The patient has successfully completed Phase I (the reductive phase) of CDT, as evidenced by the significant reduction in volume and softening of the tissues. The next step is to transition to Phase II (the maintenance phase). This involves fitting the patient for a daytime compression garment to maintain the reduction achieved and teaching them how to manage the condition long-term with a home program of self-MLD and continued bandaging at night. A is incorrect because lymphedema is a chronic condition that requires lifelong management. Discontinuing treatment would lead to a rapid re-accumulation of fluid. B is incorrect because continuing the intensive Phase I treatment is unnecessary once a plateau has been reached. The goal shifts from reduction to maintenance. D is incorrect because while a pneumatic pump can be an adjunct to Phase II, it does not replace the fundamental components of daytime compression garments and meticulous self-care. The fitting for a garment is the most critical next step.

Question 12

A 62-year-old patient with lumbar spinal stenosis presents with a primary complaint of bilateral calf pain after walking for 5 minutes. The physical therapist finds that the patient's symptoms are fully relieved with sitting and that repeated lumbar extension in standing centralizes the pain from the calves to the low back. After 2 weeks of therapy focused on an extension-based program, the patient can now walk for 15 minutes before the onset of mild back pain, with no calf symptoms.

What is the MOST appropriate progression of the intervention at this time?

Initiate a flexion-based exercise program, such as double knee-to-chest, to promote spinal flexibility in all directions.
Introduce lumbar stabilization exercises in a neutral spine position, such as planks and bird-dogs, to improve core endurance.
Progress to having the patient perform repeated extension in a prone position to achieve a greater end-range of motion. (correct answer)
Have the patient begin walking on a treadmill with a 5% incline to further challenge their walking tolerance.

Explanation: The correct answer is C. The patient has shown a positive response (centralization and improved function) to an extension-based program, which is a key principle of the McKenzie method. The symptoms have centralized and walking tolerance has improved, indicating the directional preference is correct. The next logical progression is to move to an exercise that produces a greater degree of extension, such as prone press-ups, to continue reducing the derangement and further improve function. This follows the McKenzie progression from less loaded to more loaded extension. A is incorrect because introducing flexion is contraindicated. The patient has a clear directional preference for extension; flexion would likely reverse the progress and peripheralize the symptoms. B is incorrect because while stabilization exercises may have a role later, the priority is to continue with the directional preference that is resolving the primary symptoms. Shifting focus away from the successful extension-based strategy is premature. D is incorrect because walking on an incline typically increases lumbar flexion, which would likely worsen the patient's stenosis-related symptoms and contradict the established directional preference.

Question 13

A 70-year-old patient is 6 weeks post-right cerebral vascular accident (CVA) and is receiving inpatient rehabilitation. The current focus is on improving standing balance. The patient can stand in parallel bars with minimal assistance for 30 seconds but demonstrates a weight-bearing asymmetry, with most of their weight shifted to the non-paretic left leg. They are unable to lift the left foot off the ground without loss of balance.

Which intervention represents the MOST appropriate progression to improve the patient's weight-bearing on the paretic limb?

Initiate gait training with a hemi-walker to promote functional mobility and independence.
Practice standing on a foam pad inside the parallel bars to challenge the patient's somatosensory system.
Perform small-range, rhythmic weight shifts toward the paretic right side with tactile cues at the hip. (correct answer)
Progress to tandem standing with the non-paretic left leg in front to narrow the base of support.

Explanation: The correct answer is C. The patient's primary deficit is the inability to accept weight onto the paretic limb, which is a prerequisite for safe and effective gait. The most direct and appropriate progression is to work on dynamic weight shifting toward the paretic side. This facilitates active motor control, muscle activation, and sensory awareness on the affected side in a controlled manner. A is incorrect because progressing to gait training is premature and unsafe. The patient lacks the fundamental ability to bear weight on the paretic limb, which would lead to a highly compensatory and unsafe gait pattern. B is incorrect because standing on foam is a higher-level balance challenge. It should only be introduced after the patient can manage static balance and controlled weight shifts on a firm surface. D is incorrect because tandem standing is also a higher-level balance task. Furthermore, placing the non-paretic leg in front would encourage even more weight-bearing on that limb, reinforcing the asymmetry rather than correcting it.

Question 14

A patient is 4 weeks post-autograft to the dorsum of the hand for a full-thickness burn. The patient has been wearing a thermoplastic splint to maintain the metacarpophalangeal (MCP) joints in 70° of flexion and interphalangeal (IP) joints in full extension. During today's session, the therapist notes that a small, 1 cm area of the graft appears dusky and has slight blistering at the MCP joint line when the patient performs active composite finger flexion.

What is the MOST appropriate modification to the patient's plan of care?

Discontinue all active range of motion exercises immediately and re-apply the splint, then contact the surgeon for consultation. (correct answer)
Progress to passive range of motion to ensure full composite flexion is achieved and to prevent joint contractures.
Isolate active IP joint flexion while maintaining the MCP joints in extension to avoid tension on the compromised area of the graft.
Apply a topical antimicrobial agent to the dusky area and continue with gentle active composite flexion as tolerated by the patient.

Explanation: The correct answer is A. A dusky appearance and blistering of a skin graft are signs of vascular compromise and potential graft failure. Continuing any motion that stresses this area could lead to complete loss of that portion of the graft. The safest and most appropriate action is to cease the aggravating activity, protect the area by re-applying the splint, and immediately notify the surgeon for further direction. B is incorrect because progressing to passive ROM would place even more stress on the fragile graft than active motion and would be highly contraindicated. C is incorrect because while isolating motion is a good strategy in some cases, the signs of graft compromise warrant a complete cessation of motion and medical consultation, not just a modification of the exercise. D is incorrect because while wound care is important, the primary issue is the mechanical stress causing graft compromise. Continuing the exercise, even gently, is unsafe. The therapist should not apply medications without an order.

Question 15

A 72-year-old female with severe, stable COPD (FEV1 38% predicted) is participating in a pulmonary rehabilitation program. She is performing endurance training on a stationary bicycle at 30 watts. At baseline, her SpO2 is 93% on room air. After 5 minutes of continuous cycling, her SpO2 drops to 87%. The patient's Borg dyspnea rating is 4/10, and she states she feels fine and wants to continue. She is using pursed-lip breathing correctly.

What is the MOST appropriate immediate action for the physical therapist?

Allow the patient to continue exercising but reduce the workload to 20 watts to decrease metabolic demand.
Stop the exercise, have the patient rest, and consider titrating supplemental oxygen to maintain SpO2 ≥90% during subsequent exercise. (correct answer)
Encourage the patient to push through, as an SpO2 of 87% is acceptable for short periods in patients with severe COPD.
Stop the bicycle exercise and switch to upper body ergometry, as this typically places less demand on the respiratory system.

Question 16

A 24-year-old male with a T10 ASIA A spinal cord injury is practicing transfers from his wheelchair to a mat table using a sliding board. He has achieved independence with setup but requires minimal assistance for lifting and clearing his hips. During his fifth repetition, he complains of a new, sharp, burning pain in his right wrist and hand, consistent with the median nerve distribution. He denies any acute trauma.

What is the MOST appropriate immediate modification to the transfer technique?

Change the hand position to a closed fist or have the patient use the ulnar border of his hand to bear weight on the mat. (correct answer)
Place a cushion under the patient's hand on the mat to reduce the pressure during the push-up phase of the transfer.
Instruct the patient to push through the pain, as some discomfort is expected when building strength for transfers.
Regress to a dependent transfer with a mechanical lift to allow the wrist to rest and recover fully before resuming training.

Explanation: When you encounter acute nerve symptoms during weight-bearing activities in spinal cord patients, you need to immediately modify the technique to prevent further nerve compression while maintaining functional training progression. The patient's sharp, burning pain in the median nerve distribution during transfer practice indicates acute carpal tunnel compression from repetitive weight-bearing through extended wrists. This occurs because the transfer technique is placing the median nerve in a compromised position under load. Option A is correct because changing to a closed fist or using the ulnar border eliminates wrist extension and removes direct pressure from the carpal tunnel. This modification maintains the patient's independence level while immediately protecting the median nerve, allowing transfer practice to continue safely. Option B is incorrect because simply cushioning the hand doesn't address the root problem of wrist positioning. The median nerve remains compressed in the extended wrist position regardless of surface padding. Option C is dangerously wrong. Pushing through acute nerve pain risks permanent median nerve damage and potential complex regional pain syndrome. Sharp, burning nerve pain is never "normal discomfort" and should never be ignored. Option D represents unnecessary regression. While rest might help symptoms, completely stopping functional training isn't warranted when simple positional modifications can resolve the issue while maintaining progress toward independence. NPTE Strategy: When patients develop acute nerve symptoms during therapy, always look for technique modifications that eliminate the problematic positioning first. Only consider stopping treatment if modifications aren't possible or symptoms persist despite proper technique changes.

Question 17

A 42-year-old female with stress urinary incontinence has been performing pelvic floor muscle exercises for 4 weeks. She demonstrates correct technique, with no substitution patterns, and can perform 10 repetitions of an 8-second maximal contraction with a 10-second rest. However, she continues to report leakage with coughing and when she lifts her toddler. She denies urgency or other urinary symptoms.

What is the MOST appropriate progression for her home exercise program?

Increase the hold time of the contractions to 15 seconds and increase the total number of repetitions per day.
Incorporate a quick, strong contraction of the pelvic floor muscles immediately before and during a voluntary cough. (correct answer)
Add a general core stability program focusing on the transverse abdominis and multifidus muscles.
Begin biofeedback training to ensure she is achieving a maximal contraction during her exercises.

Explanation: The correct answer is B. The patient has demonstrated good endurance and strength in isolated, non-functional contractions. Her deficit is in the timing and coordination of pelvic floor activation during moments of increased intra-abdominal pressure (coughing, lifting). The next step is to train the functional, reflexive timing of the contraction, often called 'The Knack' or a counter-bracing contraction. This directly addresses her primary complaint. A is incorrect because simply increasing the duration and volume of the static holds does not address the critical timing component needed to prevent stress incontinence. C is incorrect because while general core stability is important, it is not as specific or effective for stress incontinence as directly training the timing of the pelvic floor contraction with the triggering event. D is incorrect because she has already demonstrated correct technique. Biofeedback would be redundant and does not address the functional timing deficit.

Question 18

A patient with chronic neck pain has been using a portable conventional TENS unit at home for 3 weeks with settings of 100 pps frequency and 100 μs pulse duration. The patient initially reported 6/10 pain reduction during use, but now states the unit provides only minimal relief (1-2/10 reduction). The patient has not changed the electrode placement and has been increasing the amplitude to a strong but comfortable level.

Which of the following modifications to the TENS parameters is MOST likely to restore analgesic efficacy?

Decrease the amplitude to a level that is barely perceptible to avoid over-stimulating the nerves.
Switch to an acupuncture-like TENS setting with a low frequency (e.g., 4 pps) and a longer pulse duration (e.g., 200 μs). (correct answer)
Change the electrode placement to the dermatome corresponding to the patient's low back pain.
Instruct the patient to use the TENS for shorter durations but more frequently throughout the day to reduce accommodation.

Explanation: The correct answer is B. The patient is likely experiencing accommodation, where the nervous system adapts to the continuous, unchanging stimulus of conventional TENS. To overcome this, the stimulus parameters must be changed. Switching to an acupuncture-like (low-frequency) TENS mode provides a different type of stimulus that acts via a different neurophysiological mechanism (endogenous opioid release) and is an effective strategy to combat accommodation. A is incorrect because the amplitude for conventional TENS should be strong but comfortable. Decreasing it would make the treatment sub-therapeutic. C is incorrect because the electrode placement should be related to the site of pain. Moving them to an unrelated area like the low back for neck pain would be illogical. D is incorrect because while modulating the stimulus can help, simply changing the timing without altering the electrical parameters (frequency, pulse duration) is less likely to be effective than switching the mode of TENS entirely.

Question 19

A 52-year-old female receiving chemotherapy for breast cancer is referred to physical therapy for cancer-related fatigue. Her current exercise prescription includes treadmill walking at a moderate intensity. She arrives at her session reporting she feels unusually tired. A review of her daily lab values shows her platelet count is 45,000/µL, her hemoglobin is 10.5 g/dL, and her white blood cell count is normal.

What is the MOST appropriate modification to the plan of care for today's session?

Proceed with the planned moderate-intensity treadmill walking but monitor for signs of fatigue and bleeding.
Discontinue all activity and have the patient rest for the entire session due to the low platelet count and fatigue.
Focus on passive stretching and manual therapy to address fatigue without stressing the hematological system.
Regress the intervention to light aerobic exercise, such as light cycling or walking, with no resistance training. (correct answer)

Explanation: When treating cancer patients undergoing chemotherapy, you must carefully consider hematological values and adjust exercise intensity accordingly. This question tests your understanding of exercise modifications based on lab values and patient presentation. The patient's platelet count of 45,000/µL is significantly below normal (150,000-450,000/µL), indicating thrombocytopenia, while her hemoglobin of 10.5 g/dL shows mild anemia (normal is 12-15.5 g/dL for women). Combined with her reported fatigue, these values necessitate reducing exercise intensity to prevent complications while maintaining the benefits of physical activity. Option D is correct because light aerobic exercise allows continued cardiovascular benefits while respecting the patient's compromised hematological status. Light cycling or walking reduces bleeding risk from the low platelets while accommodating the decreased oxygen-carrying capacity from anemia. Option A is dangerous because moderate-intensity exercise with a platelet count this low significantly increases bleeding risk, especially internal bleeding that might not be immediately apparent. Option B is overly conservative—complete rest isn't necessary and eliminates the proven benefits of exercise for cancer-related fatigue. Option C focuses on passive interventions that don't address the aerobic capacity component essential for managing cancer-related fatigue. For NPTE success, remember the "traffic light" approach to exercise with cancer patients: platelet counts below 50,000/µL warrant exercise modification (yellow light), while counts below 20,000/µL typically contraindicate exercise (red light). Always balance safety with maintaining functional capacity.

Question 20

A 55-year-old male with a new transtibial prosthesis for a dysvascular amputation is participating in his third session of gait training. After a 10-minute session of walking in the parallel bars, he removes the prosthesis. The physical therapist observes a 2-cm area of non-blanchable erythema over the head of the fibula. The patient reports the area is not painful.

What is the MOST appropriate course of action for the therapist?

Provide the patient with a gel liner to wear under the prosthesis to reduce friction in that area.
Continue with gait training for another 10 minutes, as the patient is not reporting any pain.
Apply ice to the erythematous area and have the patient perform seated exercises for the remainder of the session.
Discontinue wear of the prosthesis for the day and contact the prosthetist immediately to assess the fit of the socket. (correct answer)

Explanation: The correct answer is D. Non-blanchable erythema is a sign of Stage 1 pressure injury, indicating tissue compromise due to excessive pressure. The fibular head is a common area for this in transtibial prostheses. Continuing to wear the prosthesis would lead to further skin breakdown. The absence of pain is common in patients with dysvascularity and peripheral neuropathy and should not be used to discount the severity of the objective finding. The underlying cause is improper fit, which must be addressed by the prosthetist before the patient can safely wear the device again. A is incorrect because while a gel liner might be part of a solution, adding material inside a tight socket could increase pressure. The prosthetist must be the one to make this modification. B is incorrect because continuing gait training is unsafe and will worsen the tissue damage, regardless of the patient's subjective pain report. C is incorrect because while ice may help with inflammation, the primary issue is the mechanical pressure from the ill-fitting socket. The crucial step is to involve the prosthetist.
