Deck 48: Amputations and Prosthetics

Question 1

Which is not a function of a prosthetic sock?

A) Absorb perspiration
B) Protect against skin irritation
C) Compensate for residual limb volume changes
D) Provide comfort
E) Allow direct contact between socket and skin

Answer 1

E
A prosthetic sock is a layer worn between the residual limb and the prosthetic socket that performs the functions described in answer options (A)through (D).

Question 2

A traditional body-powered above-elbow prosthesis would require how many control cables?

A) None
B) One
C) Two
D) Three
E) Four

Answer 2

C
An above-elbow body-powered prosthesis requires two control cables: one to operate the terminal device and one to operate the elbow.

Question 3

Which is true about upper and lower extremity amputations?

A) The lower the level of amputation, the greater the functional loss.
B) The higher the level of amputation, the less complicated the prosthesis.
C) The higher the level of amputation, the less prosthetic training needed.
D) The lower the level of amputation, the more joints lost.
E) The higher the level of amputation, the less residual limb length.

Answer 3

E
Answer option (A)is not true because the higher the amputation,the greater the functional loss.Options (B)and (C)are not true because the higher the amputation,the more complicated the prosthesis becomes,and more training is necessary.Option (D)is not true because the higher the amputation,the more joints are lost.

Question 4

Which of the following is a Syme's amputation?

A) Ankle disarticulation
B) Above-knee
C) Below-knee
D) Through-knee
E) Transmetatarsal

Question 5

Not all above-knee or below-knee prostheses have a _____________.

A) Socket
B) Pylon
C) Suspension system
D) Terminal device
E) Articulating joint

Question 6

Which is not an advantage of a myoelectric prosthesis?

A) Minimal or no harnessing
B) Lighter weight
