PTA145 Unit 4 test review

Define Alternating Current (DC):

• Indirect interrupted flow of charged particles per second

• Bidirectional, uninterrupted flow of charged particles changing direction at least one per second

• Unidirectional, uninterrupted flow of charged particles changing directions at least one per second

• Directional interrupted flow of charged particles per second

Which best describes the indications for E-Stim?

• Pain management

  MM strengthening

  Stim of dennervated MM

• Gate control theory

  Endogenous opiates

• A-Delta fibers

  C Fibers

  A-Beta fibers

• All are correct

Biphasic forms have:

• One phase

• There are no phases

• Two phases

• Positive & Negative

Define pulsed current:

• There is no Pulsed current

• Monophasic form that charges after electrical event

• Biphasic form that charges after electrical event

• Unidirectional and bidirectional flow of charged particles periodically ceasing for less than one second before the next electrical event.

How does the amount of adipose tissue affect impedance of the lower tissue with E-stim?

• The less amount of adipose tissue the lower the impedance

• The less amount of adipose tissue the increase impedance

• Adipose tissue does not affect impedance

• All are correct

Portable electrical stimulators for pain management are:

• N.E.M.S units

• T.E.N.S units

• Biofeedback units

• Russian units

The pulse duration to produce a response on a motor nerve compared to a sensory nerve has to be:

• Louder on motor than sensory nerve

• Same on motor than sensory nerve

• Shorter on motor than sensory nerve

• Longer on motor than sensory nerve

How does consuming ETOH by a Pt affects application of E-stim?

• 
  Pt has the right to use E-stim

• ETOH produces analgesic effects and impairs ability of Pt to safely utilize E-stim

• ETOH produces analgesic effects and increases ability of Pt to safely utilize E-stim

• All are correct

Electrical stimulation can be used for wound repair. Direct technique is defined as:

• One electrode over wound and 2nd electrode around wound

• Both electrodes over wound

• 2 electrodes around wound

• All are correct

For proper application of Iontophoresis the following are necessary:

• Therapist is skilled to do it

• Only nurses can provide meds to a Pt.

• Only medication is needed

• Water soluble medication and a Rx.
