What color is used for the ground lead in an EKG?

• A. Red
• B. Black
• C. Green
• D. Yellow

Answer: (C)

The ground lead in an EKG is typically represented by the color green. The ground lead serves as a reference point for the other leads, helping to ensure that the electrical signals obtained by the EKG machine are interpreted accurately. By serving as a baseline, the ground lead helps to minimize noise and interference, which can affect the quality of the EKG tracing. In contrast, the other colors are designated for specific functions: red is often associated with lead II or the positive electrode, black is frequently used for lead I, and yellow typically denotes lead III. This color-coding system is important for maintaining consistency in lead placement and ensuring that EKGs are conducted correctly.
