35) During of your clinical rotations, you are helping prepare a patient for mobility on the cardiac step-down unit. You place the telemetry leads but are not confident in your recall of the normal orientation. You place them as shown. A mannequin with ECG leads placed on the chest. The black lead attaches to the mannequin’s right upper chest. The white lead attaches to the left upper chest. The brown lead in on the upper abdomen. The green lead is on the right aspect of the abdomen. The red lead is on the left aspect of the abdomen.
