EKG Acquisition第 63 / 100 题
Before beginning a shift, a technician inspects the EKG machine. Which finding requires the machine be removed from service?
a.A frayed patient cable with exposed wire
b.A paper roll that is about half full
c.A standardization mark measuring exactly 10 millimeters
d.Electrode tabs stored in a sealed, unexpired package
解析
A frayed cable with exposed conductor is an electrical hazard and a source of artifact, so the machine is tagged and removed from service until repaired. A half-full paper roll is simply replaced or monitored. A 10 millimeter standardization mark is the correct calibration, and sealed unexpired electrodes are exactly what should be stocked.
