What is the MOST ideal current to use for iontophoresis?

alternating current

high volt direct current

direct current

interferential current/waveform

Answer explanation

Media Image

Interrupted currents (high volt DC) have an on/off or current duration is too short (IFC) for effective drug delivery. Continous delivery is best.

Where should EMG electrodes should be placed?

On the myotome, parallel to fibers, and far apart

As near to the muscle being monitored, parallel to fibers, & close to each other

On the dermatome, transverse to muscle fibers, and close to each other

As near to the musculotendinous junction, transverse to related fibers, & far apart

Answer explanation

Media Image

Lead/electrode setup should be placed to help create the least amount of interference.
