Which lead is placed on the right lower side of the anterior torso?

Lead LL
Lead RA
Lead RL
Lead V2

The correct answer is: Lead RL

The lead that is placed on the right lower side of the anterior torso is the right leg lead, known as Lead RL. In a standard 12-lead EKG setup, the placement of the leads is crucial for obtaining accurate readings of the heart's electrical activity. Lead RL serves as a reference point and is part of the limb leads. While it does not directly measure electrical activity like the precordial leads, it helps in grounding the EKG, providing a baseline for the other leads. The correct placement of Lead RL is essential for minimizing noise and artifacts in the recording, which can aid in better interpretation of the heart's electrical activity. Other leads correspond to different positions on the body. Lead LL is placed on the left lower side, Lead RA is on the right upper side, and Lead V2 is a precordial lead located on the left side of the sternum. Therefore, Lead RL is specifically identified as the lead that occupies the right lower side of the anterior torso, reflecting its proper location in the EKG setup.
