For anteroposterior AED pad placement in adults and children 8 years and older, which two statements are correct?

• A. Anteriorly on the left chest; Posteriorly on the right back.
• B. Anteriorly in the center of the bare chest. Posteriorly in the center of the back.
• C. Anteriorly to the left rib cage; Posteriorly to the right chest.
• D. Anteriorly on the top of the chest; Posteriorly on the bottom back.

Answer: (B)

Anteroposterior pad placement for an older child or adult is about creating a straight current path through the heart by placing one pad on the front and the other on the back in a midline position. The best anterior pad goes in the center of the bare chest so it sits over the heart, and the posterior pad goes in the center of the back, typically between the shoulder blades. This configuration ensures the shock travels through the heart rather than around the chest and keeps pads away from clothing or devices that could block conduction. This is why the correct statement is that the anterior pad should be in the center of the bare chest and the posterior pad in the center of the back. The other options place pads in non-midline or unconventional locations, which would not provide the optimal current path through the heart.
