All questions

Question 1

A 72-year-old patient with idiopathic Parkinson's disease, Hoehn & Yahr stage 4, is evaluated for a new assistive device. The patient's primary mobility limitations are severe, episodic freezing of gait (FOG) when initiating movement and attempting to pass through doorways, as well as significant retropulsive festination. The patient currently uses a standard two-wheeled walker, which seems to exacerbate the retropulsion.

Which assistive device is the MOST appropriate recommendation to specifically address this patient's gait impairments?

  1. A four-wheeled rollator with a seat and hand brakes to allow for frequent rest periods.
  2. A standard walker with tennis balls on the rear legs to provide increased friction and slow cadence.
  3. Bilateral forearm crutches to promote a more upright posture and increase trunk rotation.
  4. A U-shaped walker with reversed brakes and a laser light cueing module. (correct answer)
Explanation: This patient's specific problems (FOG, retropulsion) require specific solutions. A U-shaped walker has a wide base of support and centers the patient's mass within it, which helps counteract retropulsion. Reversed brakes, which are engaged by default and released by squeezing, prevent the walker from running away from the patient during festination. Most importantly, a laser light cueing module projects a line on the floor, providing an external visual cue that is highly effective for overcoming freezing of gait. A rollator (A) can increase festination and fall risk. A standard walker (B) is what the patient is currently using ineffectively. Forearm crutches (C) require a level of coordination and stability that a stage 4 Parkinson's patient typically lacks.

Question 2

Which contraindication must be considered when using TENS for pain management?

  1. Chronic low back pain without neurologic signs
  2. Intact sensation over the painful region
  3. Implanted cardiac pacemaker or defibrillator (correct answer)
  4. Pain rated 6/10 with movement
Explanation: This question tests the NPTE skill of safely adjusting and applying equipment according to indications and precautions. Safe application involves understanding the purpose of the device, correct adjustment, and adherence to contraindications and precautions. In this scenario, the specific device, TENS, must be applied correctly based on the patient's pain management needs and clinical guidelines. The correct answer is effective because it follows clinical protocols for safe application and adjustment, ensuring patient safety and therapeutic efficacy by avoiding interference with cardiac devices. A common wrong choice fails by ignoring a critical precaution or contraindication, such as applying TENS over areas without neurologic signs which is not a contraindication. To improve understanding, practice adjusting devices in simulated environments, review contraindications regularly, and engage in continuous clinical education to stay updated on safety standards.

Question 3

To descend stairs with axillary crutches, which sequence is correct?

  1. Affected leg, then crutches
  2. Unaffected leg, then crutches
  3. Crutches and affected leg lead (correct answer)
  4. Crutches, then unaffected leg
Explanation: When descending stairs, move the crutches and affected leg down to the next step first while the unaffected leg supports your weight. Then bring the unaffected leg down to meet them. The tempting wrong choice is leading with the unaffected leg, which is the correct pattern for going up stairs, not down.

Question 4

For a patient with a recent rib fracture, where should a gait belt be placed?

  1. At the waist over clothing (correct answer)
  2. Over the rib fracture site
  3. Around the lower rib cage
  4. Around the proximal thighs
Explanation: A gait belt is placed at the waist, over clothing, where it can anchor securely without pressing on injured structures. Avoid placing it over the rib fracture site, because pressure there can increase pain and risk further injury. The lower rib cage is too high and the proximal thighs are not the intended belt position.

Question 5

A patient has calf swelling with suspected DVT. Before applying a pneumatic compression device, what is safest?

  1. Apply low-pressure compression
  2. Use a higher pressure setting
  3. Begin with the foot and ankle
  4. Withhold until DVT excluded (correct answer)
Explanation: Applying pneumatic compression while a DVT is possible can dislodge the clot and cause a pulmonary embolism, so you must withhold it until DVT is ruled out. The most tempting wrong answer is low-pressure compression, but even low pressure over a suspected DVT is unsafe. Confirm the diagnosis before using any compression device.

Question 6

To descend a curb in a manual wheelchair, which technique is safest?

  1. Forward, front casters first
  2. Back down, rear wheels first (correct answer)
  3. Forward, rear wheels first
  4. Back down, front casters first
Explanation: To descend a curb, back down so the large rear wheels reach the lower level first. This keeps your center of gravity over the wheelbase and lets the rear wheels absorb the impact. Going forward with the front casters first is the dangerous mistake because it tips the chair forward and can pitch you out.

Question 7

A patient with poor trunk control can bear weight. Which transfer method is safest?

  1. Use a full-body sling lift (correct answer)
  2. Use a sit-to-stand device
  3. Use a stand-pivot with belt
  4. Use a sliding transfer board
Explanation: Because poor trunk control leaves you unable to safely maintain upright posture, a full-body sling lift supports the entire trunk and head during transfer even though you can bear weight. A sit-to-stand device is the most tempting choice because it uses weight-bearing legs, but it still requires trunk stability and can allow collapse. Full-body sling removes that risk.

Question 8

Which precaution should be observed when applying an AFO in spastic hemiplegia?

  1. Position ankle neutrally and ensure straps do not trigger clonus or excessive tone (correct answer)
  2. Force the ankle into maximal dorsiflexion to inhibit spasticity
  3. Apply quickly without alignment check to reduce guarding
  4. Loosen all straps to allow full plantarflexion during gait
Explanation: This question tests the NPTE skill of safely adjusting and applying equipment according to indications and precautions. Safe application involves understanding the purpose of the device, correct adjustment, and adherence to contraindications and precautions. In this scenario, the specific device, an AFO, must be applied correctly based on the patient's spastic hemiplegic condition and clinical guidelines. The correct answer is effective because it follows clinical protocols for safe application and adjustment, ensuring patient safety and therapeutic efficacy by managing tone without exacerbation. A common wrong choice fails by ignoring a critical precaution or contraindication, such as forcing maximal dorsiflexion which can trigger spasticity. To improve understanding, practice adjusting devices in simulated environments, review contraindications regularly, and engage in continuous clinical education to stay updated on safety standards.

Question 9

What is the correct procedure for applying TENS for knee osteoarthritis pain?

  1. Place electrodes over open skin lesions to improve conductivity
  2. Clean skin, place electrodes around painful area, and set intensity to strong but comfortable tingling (correct answer)
  3. Place electrodes over the eyes and increase intensity until numbness occurs
  4. Skip skin inspection if the patient reports normal sensation
Explanation: This question tests the NPTE skill of safely adjusting and applying equipment according to indications and precautions. Safe application involves understanding the purpose of the device, correct adjustment, and adherence to contraindications and precautions. In this scenario, the specific device, TENS, must be applied correctly based on the patient's knee osteoarthritis condition and clinical guidelines. The correct answer is effective because it follows clinical protocols for safe application and adjustment, ensuring patient safety and therapeutic efficacy through proper skin preparation and intensity setting. A common wrong choice fails by ignoring a critical precaution or contraindication, such as placing over open lesions which risks infection. To improve understanding, practice adjusting devices in simulated environments, review contraindications regularly, and engage in continuous clinical education to stay updated on safety standards.

Question 10

What monitoring is required after TENS initiation for postoperative knee pain?

  1. Monitor incision moisture and remove electrodes if drainage increases
  2. Monitor for increased redness, burning, or itching under electrodes and adjust intensity (correct answer)
  3. Monitor for increased bruising and increase intensity accordingly
  4. Monitor for joint crepitus and stop if present
Explanation: This question tests the NPTE skill of safely adjusting and applying equipment according to indications and precautions. Safe application involves understanding the purpose of the device, correct adjustment, and adherence to contraindications and precautions. In this scenario, the specific device, TENS, must be applied correctly based on the patient's postoperative knee pain condition and clinical guidelines. The correct answer is effective because it follows clinical protocols for safe application and adjustment, ensuring patient safety and therapeutic efficacy by detecting adverse skin reactions early. A common wrong choice fails by ignoring a critical precaution or contraindication, such as monitoring incision moisture which is secondary to skin irritation checks. To improve understanding, practice adjusting devices in simulated environments, review contraindications regularly, and engage in continuous clinical education to stay updated on safety standards.

Question 11

A 45-year-old male with a T6 ASIA A spinal cord injury has a healed stage 4 pressure injury over his right ischial tuberosity. He has a fixed, non-reducible pelvic obliquity with the left ischium sitting lower than the right. He requires a new wheelchair cushion. The primary goal is to prevent recurrence of the pressure injury on the high-risk right side while providing pelvic stability.

Which wheelchair cushion design is the MOST effective for this patient's specific needs?

  1. A multi-cell air cushion with deep immersion properties, inflating the right side to a higher pressure than the left to level the pelvis.
  2. A viscoelastic foam cushion with an embedded fluid sac positioned directly under both ischial tuberosities for equalized pressure.
  3. A custom-molded contoured foam base with a deep well carved out under the right ischial tuberosity and a build-up under the left. (correct answer)
  4. A solid gel cushion with a firm foam base and a pelvic trough to prevent anterior pelvic tilt and provide basic pressure relief.
Explanation: This patient's combination of a fixed deformity and an extremely high-risk area (healed Stage 4 ulcer) requires a highly customized solution. A custom-molded base is necessary to accommodate the fixed pelvic obliquity by building up the low (left) side. Crucially, a deep well or 'offload' area must be carved out under the high-risk right ischium to completely eliminate pressure on that site. This combination provides both accommodation for the deformity and targeted offloading. Attempting to level a fixed pelvis with air pressure (A) would create a dangerous pressure peak. A generic fluid sac (B) or gel cushion (D) would not provide the necessary specific offloading for the high-risk area or the accommodation for the fixed obliquity.

Question 12

A 55-year-old patient with post-polio syndrome presents with progressive weakness. Examination reveals 2/5 quadriceps strength, 3/5 dorsiflexor strength, and 4/5 hip extensor strength. The patient demonstrates 15 degrees of genu recurvatum in midstance and a foot drop during swing. The patient has no hip or knee flexion contractures. The primary goal is to provide stability during stance while minimizing energy expenditure during gait due to significant fatigue.

Which knee-ankle-foot orthosis (KAFO) configuration is MOST appropriate for this patient?

  1. A drop lock knee joint with a solid ankle joint set in 2 degrees of plantar flexion.
  2. A free motion knee joint with an offset posterior axis and a posterior leaf spring ankle joint.
  3. A stance control knee joint with a plantar flexion stop and free dorsiflexion ankle joint. (correct answer)
  4. An adjustable locking knee joint with a bichannel adjustable ankle locking (BiCAAL) joint.
Explanation: A stance control KAFO is ideal for this patient. It automatically locks the knee during the stance phase to control for the weak quadriceps and genu recurvatum, but unlocks during the swing phase, allowing for a more natural and energy-efficient gait pattern. This directly addresses the patient's fatigue. The plantar flexion stop at the ankle prevents foot drop in swing, and allowing free dorsiflexion facilitates a normal tibial progression over the foot in stance. A drop lock knee (A) is very stable but metabolically expensive as it remains locked throughout gait. A free motion knee (B) would not control the genu recurvatum or quadriceps weakness. An adjustable locking knee (D) functions similarly to a drop lock and does not improve energy efficiency during swing.

Question 13

A 35-year-old patient with a traumatic right transradial amputation is being fitted for a myoelectric prosthesis. The residual limb has extensive, well-healed scarring over the mid-forearm, encompassing the primary wrist flexor and extensor muscle bellies. During initial trials, the prosthetist notes extremely low amplitude and inconsistent electromyographic (EMG) signals from the dual-site electrode placement, resulting in unreliable activation of the terminal device.

What is the MOST appropriate next step to optimize control of the prosthesis?

  1. Switch to a body-powered prosthesis with a harness system, as myoelectric control is not feasible.
  2. Instruct the patient in more forceful muscle contractions and provide additional biofeedback training.
  3. Adjust the programming to significantly increase the amplifier gain and lower the signal rejection threshold. (correct answer)
  4. Move the electrodes more proximally toward the elbow to find less-affected muscle tissue.
Explanation: This is a complex troubleshooting problem. While moving electrodes (D) is a standard first step, the stem indicates extensive scarring, implying viable alternative sites may not exist. While more training (B) is always helpful, it won't solve the issue of a physiologically weak signal due to scar tissue. Abandoning myoelectric control (A) is premature. The most appropriate next step is to manipulate the device's software parameters. Increasing the amplifier gain makes the system more sensitive to the very weak muscle signals that are present. Lowering the rejection threshold allows the processor to accept these weak signals as intentional commands, rather than filtering them out as noise. This combination attempts to electronically compensate for the poor physiological signal quality caused by the scarring.

Question 14

A physical therapist is mobilizing a 68-year-old patient in the ICU who is intubated and receiving volume-cycled, assist-control ventilation. During a sit-to-stand transfer from the bed to a chair, the patient coughs vigorously. The ventilator immediately emits a series of high-pitched, repetitive alarms. The patient does not appear to be in acute respiratory distress, and oxygen saturation remains at 95%.

What is the MOST likely cause of the alarm, and what is the therapist's most appropriate immediate action?

  1. Low-pressure alarm due to a circuit disconnection; reconnect the tubing and continue the transfer.
  2. High-pressure alarm due to increased airway resistance; pause, encourage the patient to relax and exhale, and then reassess. (correct answer)
  3. Apnea alarm due to lack of spontaneous breaths; immediately return the patient to bed and call the respiratory therapist.
  4. High respiratory rate alarm due to patient anxiety; instruct the patient in pursed-lip breathing and continue the transfer.
Explanation: A vigorous cough creates a transient spike in intrathoracic and airway pressure, which will exceed the ventilator's high-pressure limit and trigger an alarm. Since the patient's oxygenation is stable and they are not in distress, the most appropriate action is to pause the activity, allow the transient event to pass, and coach the patient to relax their breathing. This addresses the cause without overreacting. A circuit disconnection (A) would cause a low-pressure alarm. An apnea alarm (C) is for lack of breathing, which is the opposite of a cough. A high respiratory rate (D) is a different alarm, and pursed-lip breathing is difficult for an intubated patient and not the primary intervention for a high-pressure alarm caused by a cough.

Question 15

A 52-year-old patient with a right transfemoral amputation is an experienced user of a C-Leg 4 microprocessor knee (MPK). The patient wants to begin an exercise program that includes using a stationary bicycle and asks the physical therapist for instructions on how to adapt the prosthesis for this activity. The therapist is aware that the MPK has specific, user-selectable modes for different activities.

Which instruction should the physical therapist provide to the patient to properly configure the prosthesis for cycling?

  1. Initiate a bounce on the toe of the prosthesis three times to engage the free-swing mode, which remains active until the next heel strike.
  2. Press and hold the button on the prosthesis to enter the standing mode, which will reduce resistance for pedaling.
  3. Perform a forceful, prolonged hip flexion movement with the prosthesis to override the stance phase resistance temporarily.
  4. Use the manufacturer's smartphone application to switch to the 'Cycling' mode before mounting the bicycle. (correct answer)
Explanation: Modern MPKs like the C-Leg 4 use a smartphone application (Cockpit app) for the user to switch between different pre-programmed activity modes. The 'Cycling' mode reduces stance resistance and allows for free, uninhibited knee flexion required for pedaling. The bouncing motion described in (A) is a common method to switch modes on some MPKs, but it is typically used to toggle the 'standing' function, not a dedicated cycling mode. The action in (C) would not reliably engage a specific mode. The standing mode (B) increases resistance to prevent buckling, which is the opposite of what is needed for cycling.

Question 16

A 6-year-old child with spastic diplegic cerebral palsy has a persistent, dynamic equinovarus deformity of the left ankle. The physical therapist is preparing to apply the first in a series of short-leg inhibitory casts to improve foot position and range of motion. The child has 10 degrees of available ankle dorsiflexion when the subtalar joint is held in a neutral position.

To apply the cast MOST effectively for correcting the varus component while promoting dorsiflexion, what is the correct sequence of manual positioning?

  1. Apply a strong dorsiflexion force to the forefoot while simultaneously everting the calcaneus to its end range.
  2. Gently evert the calcaneus to neutral, lock the midtarsal joints by dorsiflexing the first ray, and then apply a sustained dorsiflexion force. (correct answer)
  3. Maximally pronate the forefoot to stretch the supinators, then bring the calcaneus to neutral and apply a dorsiflexion force.
  4. Position the subtalar joint in slight eversion, apply upward pressure through the cuboid to break the varus, and then add dorsiflexion.
Explanation: This question tests the detailed biomechanical principles of inhibitory casting. The correct sequence is critical to avoid creating a midfoot break or peroneal muscle spasm. First, the hindfoot (calcaneus) must be brought to a neutral or slightly everted position. Then, the midtarsal joint is 'locked' by applying a dorsiflexion force specifically to the first ray, which stabilizes the forefoot against the hindfoot. Only after the foot is stabilized in this corrected alignment can a gentle, sustained dorsiflexion force be applied to the entire foot to stretch the gastrocnemius-soleus complex. Applying a strong dorsiflexion force first (A) or trying to pronate the forefoot independently (C) will cause a break at the midtarsal joint, resulting in a rocker-bottom foot deformity, not a true correction of the equinus.

Question 17

A 55-year-old patient with a 20-year history of type 1 diabetes and severe peripheral neuropathy presents with a sudden onset of a warm, swollen, and erythematous left foot, without any known trauma. The patient is afebrile and white blood cell count is normal. Radiographs reveal early signs of osseous fragmentation and joint subluxation at the tarsometatarsal (Lisfranc) joint, consistent with Eichenholtz Stage 1 Charcot neuroarthropathy.

What is the MOST appropriate immediate device prescription for the management of this patient's foot?

  1. A custom-molded accommodative foot orthosis with a metatarsal bar to offload the forefoot.
  2. A controlled ankle motion (CAM) walker boot to limit ankle motion and provide partial offloading.
  3. A total contact cast (TCC) to provide complete immobilization and maximal offloading of the foot. (correct answer)
  4. A Charcot Restraint Orthotic Walker (CROW) boot for definitive management and long-term ambulation.
Explanation: Acute (Eichenholtz Stage 1) Charcot neuroarthropathy is a medical emergency requiring immediate and aggressive offloading to prevent catastrophic bone destruction and deformity. The gold standard for this is the total contact cast (TCC). It immobilizes the foot and ankle and disperses weight-bearing forces over the entire lower leg, maximally offloading the fragile bones of the foot. A CAM walker boot (B) provides significantly less offloading and allows for removal, which is contraindicated in the acute phase. A foot orthosis (A) is completely inadequate. A CROW boot (D) is a definitive orthosis used later, once the acute inflammatory process has resolved and the foot has progressed to a more stable stage (Stage 2 or 3).

Question 18

A physical therapist and an assistant are preparing to perform a dependent bed-to-chair transfer using a ceiling-mounted mechanical lift for a 550 lb (250 kg) patient. The patient is post-operative day 2 following an exploratory laparotomy with a large midline abdominal incision and has a prominent, heavy pannus. The patient is obtunded and unable to assist.

Which sling type and application technique is MOST appropriate to ensure patient safety and comfort?

  1. A universal mesh sling, applied by log-rolling the patient, ensuring the leg straps are crossed to prevent hip abduction.
  2. A hammock-style sling placed under the patient, with the leg straps positioned around each thigh individually.
  3. A bariatric band and pannus support sling system, applied with the patient in a semi-reclined position to minimize log-rolling. (correct answer)
  4. A standing and transfer aid sling, positioned around the patient's trunk after raising the head of the bed to 90 degrees.
Explanation: This patient's size, surgical incision, and large pannus present multiple safety challenges. A specialized bariatric sling system with a dedicated pannus support is essential. This system uses multiple smaller bands that can be slid under the patient with minimal turning, avoiding the need for log-rolling which would stress the abdominal incision. The pannus support lifts and holds the pannus, preventing gravitational pull on the incision and allowing the main sling components to be positioned correctly. A universal sling (A) or hammock sling (B) would be extremely difficult to place without excessive patient movement and would concentrate pressure dangerously close to the incision. A standing aid sling (D) is completely inappropriate as the patient is dependent and cannot weight-bear.

Question 19

A patient is being treated for a post-traumatic right elbow flexion contracture. Active and passive range of motion is limited to 25-90 degrees of flexion. The physician has prescribed a dynamic extension orthosis to be worn at night. The physical therapist is instructing the patient on how to correctly set the tension of the device.

Which instruction MOST accurately reflects the principle of low-load, long-duration stretching for this device?

  1. Increase the tension until a strong, painful stretch is felt at the end range of extension to maximize tissue creep overnight.
  2. Set the tension to a level that brings the elbow to its end range of extension and creates a firm, uncomfortable sensation.
  3. Apply tension that creates a mild, tolerable stretch at the end range of extension, which can be maintained for 6-8 hours. (correct answer)
  4. Set the tension to move the elbow 5-10 degrees beyond the passive end range to create plastic deformation of the capsule.
Explanation: The therapeutic principle behind dynamic splinting for contractures is low-load, long-duration stretching (LLLD). This involves applying a gentle, tolerable force to the joint over a prolonged period. This promotes tissue remodeling and plastic deformation without causing inflammation, pain, or protective muscle guarding. Therefore, the tension should be set to create only a mild stretch that the patient can comfortably tolerate for the entire wearing period (e.g., overnight). Aggressive, painful stretching (A, B, D) is counterproductive, as it can lead to increased inflammation, muscle spasm, and heterotopic ossification, ultimately worsening the contracture.

Question 20

A 45-year-old patient with a transtibial amputation is a K-level 3 ambulator who works as a landscape architect, requiring them to walk on uneven terrain such as grass, gravel, and slopes. They would also like to be able to jog for 1-2 miles on a treadmill for exercise. They are currently using a solid ankle cushion heel (SACH) foot and find it unstable on uneven ground and lacking in responsiveness.

Which category of prosthetic foot would BEST meet this patient's occupational and recreational needs?

  1. A multi-axial, dynamic response foot with a split keel or toe design. (correct answer)
  2. A single-axis foot to provide enhanced knee stability through rapid plantar flexion at initial contact.
  3. A flexible-keel foot designed primarily for comfortable, variable-cadence walking on level surfaces.
  4. A microprocessor-controlled ankle/foot system to automatically adapt to different slopes and surfaces.
Explanation: This patient requires a prosthetic foot that can meet two distinct, high-level demands: ground compliance for uneven terrain and energy return for jogging. A multi-axial, dynamic response foot is designed for exactly this. The multi-axial component allows for inversion/eversion and rotation to conform to uneven surfaces, enhancing stability. The dynamic response (carbon fiber) keel stores energy during midstance and releases it at toe-off, providing propulsion for jogging and reducing the energy cost of walking. A single-axis foot (A) enhances stability but lacks energy return and ground compliance. A flexible-keel foot (C) is a step up from a SACH foot but lacks the significant energy return needed for jogging. A microprocessor foot (D) is an excellent option but is typically prescribed for K3 users focused on negotiating slopes and stairs with enhanced safety; the dynamic response foot is more specifically suited for the added demand of jogging.
