Question

A nurse is preparing a client for a 12-lead electrocardiogram. Which anatomical site indicates correct placement of the electrodes?

Fourth intercostal space, left sternal border, to obtain lead V3

Left midaxillary line, third intercostal space, to obtain lead V6

Fifth intercostal space, left midclavicular line, to obtain lead V4

Right sternal border, second intercostal space, to obtain lead V1

Answer 1

The correct anatomical site for placing the electrodes for a 12-lead electrocardiogram to obtain lead V3 is the fourth intercostal space, left sternal border.

Step-by-step explanation:

The correct anatomical site for placing the electrodes for a 12-lead electrocardiogram is the Fourth intercostal space, left sternal border to obtain lead V3. The 12-lead electrocardiogram uses 10 electrodes placed on the patient's skin. Each electrode is responsible for collecting electrical signals from specific leads. The leads provide different views and information about the heart's electrical activity. For example, the Fourth intercostal space, left sternal border placement is used to obtain lead V3, which gives information about the activity in the anterior wall of the left ventricle.
