When performing CPR, which anatomical landmark is most critical for proper hand placement?

• A. The xiphoid process
• B. The sternum
• C. The clavicle
• D. The pelvis

Answer: (B)

The sternum is critical for proper hand placement during CPR because it serves as the central point on the chest where compressions are applied. The correct technique involves positioning the heel of one hand on the lower half of the sternum, specifically at the center of the chest, and placing the other hand on top, interlocking the fingers. This positioning ensures that compressions are directed effectively toward the heart, maximizing blood flow. Using the sternum as a landmark helps to ensure that the compressions are both deep enough to circulate blood and located in the right anatomical area, reducing the risk of injury to underlying organs or structures. Proper placement on the sternum is essential for effective CPR, making this anatomical landmark particularly important during resuscitation efforts.
