P. 25
A medical assistant obtains the tracing shown above on a patient. Which of the following
actions should the medical assistant take?
A. Replace the electrodes on the patient’s extremities.
B. Place the patient in Trendelenburg’s position.
C. Ensure precordial lead wires are crossed to balance polarization.
D. Remind the patient to remain as still as possible.
Your response:
Remind the patient to remain as still as possible.
Correct response:
Remind the patient to remain as still as possible.
Rationale: Muscle movement produces a measurable electrical impulse. Reduce patient anxiety,
warm a patient who is shivering, instruct them to remain as still as possible and refrain from
talking. Moving limb electrodes as close to the trunk as possible can reduce interference.
