your bladder prior to the test." And rest for 10 to 30 min prior to the test.
2. A patient care technician is performing a 12-lead EKG for a patient . the technician should use
which of the following as a reference to compare the cardiac complex during a cardiac cycle on
an EKG tracing? - ANS ✔ - Calibration marks. They indicate standardization on the machine for
recording and a reference to compare with the cardiac complexes during a cardiac cycle on an
EKG tracing. Calibration marks are small, rectangular waveforms that typically appear at the
beginning of each lead and indicate the standard paper speed and amplitude of the EKG
3. A patient care technician is planning to clean EKG equipment. which of the following actions
should the technician plan to take ? - ANS ✔ - Wipe the equipment with a soft cloth moistened

infarction and report to the nurse immediately? - ANS ✔ - The technician should identify that ST
segment elevation with pathologic Q waves and T wave inversion indicates a myocardial
infarction. Report asap
5. A patient care technician should identify which of the following artifacts is present in the tracing
below? - ANS ✔ - Somatic tremor. Present in the tracing. Somatic tremor is an artifact
characterized by uneven spikes on the EKG tracing. The most common cause of this artifact is
