During a thoracic laminectomy, a rapid loss of the right PTN cortical responses occurs.
The cervical response is too poor to evaluate, and the popiteal fossa responses are
unchanged. What should you do first? - Answer- inform the surgeon immediately and

During a scoli surgery, you recognize a gradual latency increase of 3.5ms in the PTN
cortical response, the subcrotical response appears t be shifted out almost as much. All
response amplitudes are unchanged. What is the appropriate action to take? - Answer-
Check the latencies of the PF and MN responses to see if they are also shifted,
indicating a possiblle temp effect. Verify by checking the patient's body temp
Midazolam is what type of drug? - Answer- Benzodiazepine

Cardiac activity appears on the CSA/DSA display as - Answer- Delta activity
What is the most important means of preventing the spread of infection - Answer-
Handwashing
Trancranial Motor Evoked Potentials transmit primarily through which spinal cord tract?
- Answer- The lateral corticospinal tract
