A recommended method of monitoring infusion motor artifact from intravenous infusion pumps is to place two electrodes on?

Placing two electrodes on the infusion pump apparatus is a recommended method for monitoring infusion motor artifacts. This approach is effective because it allows for direct measurement of the electrical noise that the pump may generate during its operation. By capturing this interference at its source, it becomes easier to discern between true neurological signals from the EEG and those artifacts that may complicate the interpretation of the data.

Monitoring the infusion pump itself helps in identifying specific patterns of distortion caused by the pump's mechanical or electrical functions, which can then be documented and possibly filtered out during analysis. This makes it significantly simpler to ensure that the EEG readings reflect the brain's electrical activity without being obscured by extraneous signals generated by the infusion equipment.

The other options may provide less effective methods for monitoring artifacts. For example, placing electrodes on the IV tubing or the patient's hand may not adequately capture the direct influence of the pump, while placing them on the chest would typically not relate directly to infusion artifacts and may introduce unrelated signals that could confuse the readings. Thus, the choice of the infusion pump apparatus maximizes the reliability of EEG data in the presence of intravenous therapy.
