CNIM Exam Fundamentals and Professional Practice Flashcards

Which professional society publishes evidence-based guidelines most relevant to IONM practice standards in the United States?

Answer: American Society of Neurophysiological Monitoring (ASNM)

ASNM publishes IONM-specific practice guidelines, position statements, and standards that directly guide clinical IONM practice and inform the CNIM examination content.

Patient positioning artifacts in evoked potential recordings are best prevented by:

Answer: Conducting a systematic pre-positioning and post-positioning signal check with team communication

Systematic pre- and post-positioning signal comparison, combined with team communication about positioning risks, is the best practice to distinguish positioning-related artifacts from surgical injury.

The concept of 'false positive' in IONM refers to:

Answer: An alarm triggered by non-surgical factors (anesthetic, physiological, technical) without actual neural injury

A false positive IONM alarm occurs when alarm criteria are met due to anesthetic changes, physiological factors, or technical artifacts rather than actual surgical neural injury.

Which infection control measure is mandatory when placing needle electrodes for intraoperative EMG recording?

Answer: Single-use, sterile subdermal needle electrodes with standard precautions and proper needle disposal

Single-use sterile subdermal needle electrodes, standard precautions, and proper sharps disposal are mandatory infection control measures for intraoperative EMG needle electrode placement.

The 'wake-up test' (Stagnara test) during spinal deformity surgery is an adjunct to IONM that assesses:

Answer: Motor function by temporarily lightening anesthesia to allow the awake patient to move their extremities on command

The wake-up test involves lightening anesthesia to allow the patient to follow commands and move extremities, providing direct behavioral assessment of motor function as a complement to electrophysiological monitoring.

During a case with active IONM, if the surgeon requests that monitoring be discontinued mid-case without a clinical reason, the CNIM practitioner should:

Answer: Discuss the clinical implications with the surgeon and document the request; comply only after informed decision by the responsible physician

Requests to discontinue IONM mid-case require professional discussion of clinical implications; the CNIM practitioner must document the request and the decision made by the responsible physician.
