At the right lower rib cage in a nonmuscular location, which lead is used?

• A. Lead Snow
• B. Lead Fire
• C. Lead Grass
• D. Lead Smoke

Answer: (C)

The main idea here is choosing the chest lead that views the heart from the right-side, using a placement that minimizes muscle interference. The lead used at the right lower rib cage in a nonmuscular location is the Grass lead. This position gives a cleaner signal from the right side of the heart, especially the right ventricle, by being on a less muscular area and near the rib margin for good skin contact. It’s the designated option for that specific site, which is why Grass is the correct choice. The other named leads correspond to different chest locations and wouldn’t be placed at the right lower rib cage.
