Q

increase effects of cryotherapy on the body

blood viscosity
nerve conduction velocity
tissue extensibility
vasoconstriction

A

increased BV
decreased NCV
decrease TE
increased vasoconstriction

17
Q

A MHP is applied to a pts lumbar spine in supine w several layers of toweling for insulation. Given this application, which method of heat exchange occurs with the application of MHP

convection
conversion
conduction
evaporation

A

conduction

18
Q

PTA is checking for presence of contraindications prior to ice massage to a pts L Achilles tendon. which is LEAST appropriate to ask the pt

Do you know if you have a tumor in the area?
Have you ever been diagnosed with peripheral vascular disease?
Do you have nerve damage in this area?
Do you have severe pain, numbness and color changes in fingers when exposed to cold?

A

do you know of you have a tumor in the area?

19
Q

movement of particles to accelerate the thermal component of a modality such as in fluidotherapy or whirlpool would best exemplify?

convection
conversion
radiation
conduction

A

convection

conversion = nonthermal form of energy; chemical, mechanical or electrical (ultasound,diathermy)

A PTA tests a small area of the skin for hypersensitivity prior to using cold immersion bath. the pt begins to demonstrate evidence of cold intolerance within 60 seconds after cold application. the most appropriate response is to.

continue w cold immersion bath
discontinue cold application & document findings
select an alternative cytotherapeutic agent
limit cold exposure to 10 min or less

A

discontinue cold application & document findings

26
Q

a PTA explains to the pt the expected stages of perception experienced during a cryotherapy intervention. what is the “typical” sequence of sensation to cold?

Cold, burning, numbness, throbbing
Cold, numbness, burning , aching
Cold, burning, aching, numbness
Cold, aching, throbbing, numbness

A

cold, burning, aching, numbness

27

70 pps
100 pps
150 pps
25 pps

A

70 pps
