New York State Basic Emergency Medical Technician (EMT-B) Practice Exam

What is the appropriate hand position for performing external cardiac compressions on a 4-year-old child?

1. Heel of one hand

2. Both hands together

3. Fingers interlocked

4. Flat palm

The correct answer is: Heel of one hand

For a 4-year-old child, the appropriate hand position for performing external cardiac compressions is with the heel of one hand. This technique allows for effective compressions by focusing the force on the lower half of the sternum while minimizing the risk of injury to the child's fragile ribs. Using the heel of one hand provides adequate depth and allows the rescuer to maintain better control over the compression technique without excessive force being applied. In pediatric CPR, especially for younger children, it is essential to avoid using both hands together or interlocking fingers, as these methods are more suited for adults or larger children. The flat palm method is also less effective because it does not provide the proper pressure needed for effective circulatory support. Proper hand positioning ensures that the compressions are both effective and safe, adhering to pediatric resuscitation guidelines.
