Question 1

Your client is an elderly woman,also receiving renal dialysis,but who is otherwise a candidate for a transfemoral prosthesis prescription.Which is the following would be the least likely to benefit this individual?

Accepted Answer

A total suction socket may not be suitable for an elderly patient on renal dialysis due to potential skin issues and volume fluctuations in the residual limb.

Question 2

Which of the following imposes the greater energy requirement during gait?

Accepted Answer

A

Question 3

Which of the following is not true regarding the fluid-filled friction mechanism of a prosthetic knee unit?

Accepted Answer

C

Question 4

Question 5

An SC/SP suspension has one motion advantage (SC feature):__________________ and one functional disadvantage (SP feature):________________________ but may be the only option for this level of transtibial amputation:___________________________.

Accepted Answer

An SC/SP suspension provides medial-lateral support, which is advantageous for stability. However, it can make kneeling difficult, which is a functional disadvantage. It may be the only option for a short tibial limb due to the need for additional suspension and support.

Question 6

Circumduction is a displacement exhibited in swing phase if

Accepted Answer

Circumduction, a compensatory movement pattern, can occur for various reasons during the swing phase of gait, including when the prosthesis is too long, the patient is reluctant to bend the knee, or the socket is loose. These factors can lead to an unnatural circular motion to advance the leg during walking.

Question 7

A transtibial socket is aligned on the shank to enhance loading on the patellar ligament,prevent genu recurvatum,and facilitate quadriceps contraction; it is also aligned to reduce loading on the fibular head.What angle accomplishes the former and what angle accomplishes the latter benefit?

Accepted Answer

Slight flexion of the socket enhances loading on the patellar ligament, prevents genu recurvatum, and facilitates quadriceps contraction. Slight lateral tilt reduces loading on the fibular head.

Question 8

The prosthetic knee unit has the following repair list to be done: tighten friction mechanism,replace extension bumper,tighten or replace the extension strap,and repair piston.What ambulation knee problems,in order,would be noted prior to the repairs?

Accepted Answer

The answer of The prosthetic knee unit has the following...

Question 9

The prosthetic examination includes

Accepted Answer

The prosthetic examination should include both A and B. A thorough examination of the patient standing and during gait will reveal any abnormalities or issues with the prosthesis. Additionally, examining the prosthesis itself (off the patient) will allow for any necessary adjustments or repairs to be made.

Question 10

In what position should the transfemoral knee bolt be located relative to a line extending from the trochanter to the ankle (TKA line)for maximal stability?

Accepted Answer

The transfemoral knee bolt should be located more posteriorly relative to the TKA line for maximal stability. This positioning helps in providing a more stable base of support and aids in preventing the knee from buckling under the user's weight.

Question 11

Standing a transtibial prosthesis on a table for examination,the anterior socket bulge and the posterior brim should be

Accepted Answer

When standing a transtibial prosthesis on a table for examination, the posterior brim should be slightly higher (about 1-2cm) than the anterior socket bulge. This is called the "anterior-posterior" tilt and helps to align the knee joint and prevent the knee from buckling forward during gait. Therefore, choice B is the best option.

Question 12

A client may be more functional on uneven terrain if the prosthetic foot is a SAFE foot rather than traditional SACH because of its

Accepted Answer

The SAFE foot allows for medial-lateral motion, which provides better adaptability on uneven terrain compared to the rigid SACH foot.

Question 13

Which two sides of the quadrilateral socket are higher to maintain proper support?

Accepted Answer

The answer of Which two sides of the quadrilateral socket...

Question 14

Which of the following accurately depicts the most common cause of amputation and the age/gender affected?

Accepted Answer

Trauma, particularly from accidents or military injuries, is the most common cause of amputation, with young adult males being the most affected demographic.

Question 15

A frail elderly person may be fitted with a single-axis articulated foot with a soft rear bumper for all of the following reasons EXCEPT

Accepted Answer

Single-axis articulated feet with a soft rear bumper do not specifically allow for easier dorsiflexion. They are designed to provide stability and some degree of mobility, but the soft rear bumper is primarily for shock absorption upon heel strike, not for facilitating dorsiflexion. Dorsiflexion ease is more related to the overall design of the foot and its articulation mechanism rather than the softness of the rear bumper.

Question 16

Explain why an endoskeletal prosthesis may require special care as well as occasional repair.
