What problem may occur when performing intraoperative BAERs using compressible tubing and headphones
- patients post-op hearing can become impaired
- a contamination of the sterile field can occur
- the compressible tubing can become obstructed and obscure the sound to the ear 1 / 4
- their use may cause trauma to the ear canal and should be avoided - ANSWER-
Compressible tubing can become obstructed and obscure the sound to ear
An "after-discharge" can occur on the cortical EEG recording following
- a seizure recorded in the OR
- electrical stimulation of the exposed cortex
- introduction of 60 Hz artifact
- electrocautery - ANSWER-electrical stimulation of the exposed cortex
For median nerve stim, the cathode is placed
- between the tendons of palmaris longus and flexor carpi radialis muscle
- on the dorsal side of wrist, approx 2-3cm from the ulnar nerve
- 4-5 cm distal to anode
- midway between the tendon and the posterior border of the medial malleolus -
ANSWER-between the tendons of palmaris longus and flexor carpi radialis muscle
During MVD surgery to relieve a hemifacial spasm
- it is necessary to monitor EMG from CN III
- a stimulation of CN VIII elicits a response from the mentalis muscle
- the buccal branch of CN V will likely show the most EMG activity
- Cz-Fpz should be monitored for median nerve stimulation - ANSWER-stim of
CN VII elicits a response from the mentalis muscle

- less than 50 kohms
- more than 10,000 ohms
- less than 5,000 ohms
- less than 10 megohms - ANSWER-less than 5,000 ohms

4. N18 - ANSWER-N13
The initial waveform recorded of a near-field potential is
- always obscured by stimulus artifact
- negative due to depolarization of membrane potentials
- positive due to electronic depolarization of the membrane under the recording
electrode
- of very low amplitude due to the significant distance between the generator and
- / 4
recording electrode - ANSWER-Positive due to electrotonic depolarization of the membrane under the recording electrode
