Biophysical Agents USA Exam Questions
With Correct Answers
what |are |heat |modalities |used |for |- |CORRECT |ANSWER✔✔-Promote |relaxation |; |Reduce |pain |;
|Increase |blood |flow |; |Facilitate |tissue |healing; |Prepare |stiff |joints |and |tight |muscles |for |
exercise
modality |options |that |increase |tissue |temp |1-3 |cm |- |CORRECT |ANSWER✔✔-Moist |heat |packs; |
Paraffin; |Fluidotherapy; |Warm |whirlpool; |Microwaveable |gel |packs; |Air-activated |heat |wraps; |
Electric |heating |pads
Modality |options |that |increase |tissue |temp |1-5 |cm |- |CORRECT |ANSWER✔✔-Continuous-wave |
ultrasound; |Continuous |shortwave |diathermy |(CSWD)
what |are |the |types |of |superficial |heat |- |CORRECT |ANSWER✔✔-Moist |Heat |Pack |(MHP); |
Paraffin; |Fluidotherapy; |Infra-red
what |is |thermal |conductivity |- |CORRECT |ANSWER✔✔-Heat |flow |through |tissues |varies |with |
the |type |of |tissue. |
Example: |Adipose |tissue |acts |as |an |insulator |because |it |has |a |low |thermal |conductivity
Changes |in |surface |tissue |temperature |depends |on |- |CORRECT |ANSWER✔✔-Intensity |of |the |
heat |applied; |The |time |of |heat |exposure; |The |thermal |medium |for |surface |heat
| (Product |of |thermal |conductivity, |density, |& |specific |heat)
what |are |the |methods |of |heat |transfer |- |CORRECT |ANSWER✔✔-CONDUCTION; |CONVECTION; |
RADIATION
, what |is |conduction |- |CORRECT |ANSWER✔✔-occurs |when |the |kinetic |motion |of |atoms |& |
molecules |of |one |object |is |passed |on |to |another |object
Direct |contact
i.e. |Paraffin, |MHP
what |is |parrafin |- |CORRECT |ANSWER✔✔-mixture |of |wax |& |mineral |oil |that |is |melted; |Stored |
in |a |thermostatically |controlled |stainless |steel |or |plastic |unit |in |a |range |between |126 |-134 |˚F; |
Usually |a |15 |- |20 |minute |treatment
Important |considerations:
Specific |Heat; |Paraffin |wax |has |a |lower |specific |heat |than |water |therefore |it |takes |less |thermal
|energy |(joules) |to |raise |the |temperature |of |paraffin |when |compared |with |water
what |is |the |relevance |of |parrafin |- |CORRECT |ANSWER✔✔-Less |chance |of |burns |w/ |paraffin |
wax |treatment
Good |conduction |properties |due |to |higher |skin |temperatures
Wax |heats |more |slowly |than |water |
Mineral |oil |drops |the |melting |point |of |paraffin |so |it |is |molten |(liquid) |at |lower |temperatures
what |are |important |considerations |of |parrafin |- |CORRECT |ANSWER✔✔-Paraffin |in |the |molten |
state |surrounds |irregular |surfaces |to |allow |an |even |distribution |of |heating
what |is |the |clinical |relevance |of |paraffin |- |CORRECT |ANSWER✔✔-It's |commonly |used |to |treat |
distal |extremities, |i.e. |fingers, |hands, |wrist; |ankle, |foot |& |toes
Patient |positioning |issues: |strongly |recommended |to |treat |bilateral |hand |conditions, |i.e. |RA
painting |on |paraffin |- |CORRECT |ANSWER✔✔-Difficult; |Cools |very |quickly; |Messy
glove |method |paraffin |- |CORRECT |ANSWER✔✔-Most |common |method; |Low |to |moderate |
heating; |Safe |due |to |low |risk |of |burns; |Allows |for |excellent |patient |positioning
