CNIM PRACTICE EXAM 1 2023 with Complete Solutions During a median nerve preoperative study, a patient has discomfort at the wrist. Stimulation electrodes are 10 mm gold disk, stimulus intensity is 20 mA, and stimulus duration is 100 μsec. Which of the following would most likely reduce the patient's discomfort while maintaining adequate stimulation? - ANSDecrease number of repetitions What is not an advantage of epidural recordings? - ANSAbsence of significant artifact The stimulation rate is determined by the - ANSanalysis time Somatosensory evoked potentials are less reliable in patients with ? - ANSNeuromuscular disease When placing PTN stimulator you should not - ANSSecure the tape and bands around the whole ankle A differential amplifier with a Gain of 1,000,000 has a 0.2 μV signal at its positive input and a 0.8 μV signal at its negative input. The output will be: - ANSA downward peak of 0.6V The lumbar potential is generated from - ANSPost-synaptic responses The P31 response to posterior tibial nerve stimulation - ANSIs recordable over a generalized region of scalp Which of the following has the greatest effect on
