[Correct response indicated in bold font.]

  1. [Select the correct response.] According to the article, ______________ a residual limb is crucial to producing a well-fitting prosthetic socket.
    • A. designing
    • B. adjusting
    • C. casting
  2. (True or False) ______________ Prosthetists base their selection and application of a particular casting technique both on their anecdotal experience and on their foundational education.
  3. [Select the correct response.] Based on existing literature, _____________ scientific evidence exists to guide a prosthetist’s choice of casting technique.
    • A. little-to-no
    • B. a moderate amount of
    • C. a plethora of
  4. [Select the correct response.] The air bladder and pump are connected and the bladder is pressurized to about _____________ while the plaster cup is _____________.
    • A. 10 mm Hg…drying
    • B. 20 mm Hg…curing
    • C. 20 mm Hg…settling
    • D. 10 mm Hg…hardening
  5. (True or False) ____________ Five-inch rigid plaster is used to apply two layers over the residual limb, minimizing any overlap through a shift technique.
  6. [Select the correct response.] Large areas of overlap and using too many layers of plaster ____________ the effectiveness of the pressure bladder.
    • A. increases
    • B. maintains
    • C. reduces
  7. (True or False) _______________ Only patients who underwent a unilateral transtibial amputation and were cast using the Icex casting procedure were included in the study.
  8. (True or False) ______________ Most of the 82 amputations included in the study were caused by diabetes or trauma.
  9. [Select the correct response.] The mean volume reduction produced by the pressurized casting technique was statistically significant at ___________ level(s).
    • A. one
    • B. two
    • C. all three
  10. (True or False) ______________ The volume reduction impacted the effectiveness of the casting technique, but it did not change the shape of the residuum.
  11. [Select the correct response.] The impact of vacuum-assisted casting on the residual limb’s volume is ____________.
    • A. measurable
    • B. quantifiable
    • C. unknown
  12. (True or False) _____________ The difference in volume reduction is attributed to the amount of bone present and limited soft tissue in the proximal region of the residuum.
