Question

When placing electrodes on the patient for telemetry, in which of the following locations should an EKG technician place the ground electrode?

a) On the right leg
b) On the left leg
c) Over the patient's chest
d) On the patient's forehead

Answer 1

In a standard 12-lead ECG, the ground electrode should be placed on the right leg to serve as a reference point for accurately detecting the heart's electrical signals.

Step-by-step explanation:

The question is about the placement of the ground electrode for an electrocardiogram (ECG). In standard ECG lead placement, electrodes are carefully placed on the patient's body to record their heart's electrical activity. When conducting a 12-lead ECG, 10 electrodes are positioned in specific locations: six on the chest and four on the limbs. The ground electrode, traditionally, is placed on the right leg. This electrode serves as a reference point and is essential for the accurate detection of the heart's electrical signals.
