Question 8

Which orthosis is a prefabricated orthosis made of foam,has a cotton cover and hook-and-loop closure in the back,and is used for neck sprains?

Accepted Answer

A soft collar made of foam with a cotton cover and hook-and-loop closure in the back is a common type of prefabricated orthosis used for neck sprains. The other options listed are different types of orthoses used for various conditions but are not specific to treating neck sprains.

Question 9

Which component of an upper arm prosthetic must be molded to a patient's residual limb for a proper fit that is directly related to the patient's requirements for use and wear time?

Accepted Answer

The socket is the component of an upper arm prosthetic that must be molded to a patient's residual limb for a proper fit that is directly related to the patient's requirements for use and wear time. This is because the socket is the part of the prosthetic that provides support and retention for the device. Making sure it fits properly is crucial for comfort, stability, and overall functionality of the prosthetic.

Question 10

This prosthesis assists patients in traversing most environmental barriers and allows some vocational or exercise activity beyond simple locomotion.At what activity level would this prosthesis be ranked?

Accepted Answer

K3 level prostheses are designed for patients who are capable of traversing most environmental barriers and have the ability to engage in vocational, therapeutic, or exercise activities beyond simple locomotion.

Question 11

Which of the following is the least rigid lumbosacral orthosis available in varying widths and lengths that provides support and compression to the abdominal muscles,which in turn support the lower back?

Accepted Answer

An abdominal binder provides the least rigid support to the lower back and is available in varying widths and lengths to provide support and compression to the abdominal muscles, which in turn support the lower back. The other options listed are more rigid and provide support to the thoracic and lumbar spine in addition to the abdominal muscles.

Question 12

Select the best orthosis for a child with spastic hemiplegia.

Accepted Answer

The S.W.A.S.H. (standing, walking, and sitting hip orthosis) is the best choice for a child with spastic hemiplegia as it can help improve posture, gait, and overall functionality. It provides support to the hip and pelvis, while allowing for freedom of movement in the lower extremities. This can help improve the child's walking ability and decrease spasticity in the affected leg.

Question 13

Which knee prosthetic is inherently the most stable and safe?

Accepted Answer

Locking knees in prosthetics are designed to provide maximum stability, especially for users who require additional support during activities or are in the early stages of rehabilitation. They lock during the stance phase to prevent the knee from bending and causing a fall, making them inherently the most stable and safe option among those listed.

Question 14

Which orthoses would you select for immobilization of an ankle following surgery?

Accepted Answer

Both the boot walker and cam walker are suitable for immobilization of the ankle following surgery. They provide support and protection to the foot and ankle area while allowing for some degree of mobility. The stirrup splint may not provide adequate support for the ankle following surgery, so the boot or cam walker would be a better choice. Therefore, the best choice would be a combination of A and B, the boot walker and cam walker.

Question 15

Which prosthetic suspension method would be described as creating an airtight socket through the use of an expulsion valve?

Accepted Answer

The description of "creating an airtight socket through the use of an expulsion valve" refers to the suction valve suspension method, which uses suction to hold the prosthetic limb in place. Locking pins, patella straps, and harnesses are all different types of prosthetic suspension methods that do not involve pressure or suction.

Question 16

For which diagnosis would you recommend a shoe that has extra depth to accommodate a custom arch support,has a hidden rocker bottom to decrease pressure on the metatarsal heads,is covered by insurance,and is seamless?

Accepted Answer

A shoe with extra depth and a hidden rocker bottom is recommended for patients with diabetes to help prevent foot ulcers and decrease pressure on the metatarsal heads. Insurance may cover shoes for diabetic patients and a seamless design helps prevent further irritation. While a custom arch support may be helpful for other conditions such as plantar fasciitis or heel spurs, the specific features mentioned in the question point towards a shoe for diabetic patients. An ankle fracture would require a different type of shoe or boot for immobilization and support.

Question 17

Which orthoses would you select for a patient with anterior cruciate ligament (ACL),posterior cruciate ligament (PCL),or medial collateral ligament (MCL)tears?

Accepted Answer

A combined instability orthosis is specifically designed to provide support and stability for multiple ligament injuries, such as ACL, PCL, and MCL tears.
