Question

While performing CPR on an adult, What is the appropriate depth of chest compressions?

1) 1 inch
2) 1 ½ inches
3) 2 inches
4) 2 ½ inches

Answer 1

The correct depth for chest compressions during CPR on an adult is at least 2 inches (5 cm) to ensure effective circulation of the blood to the brain and other organs.

Step-by-step explanation:

When performing CPR on an adult, the appropriate depth of chest compressions should be at least 5 cm (2 inches) deep. This level of compression is necessary to effectively push blood through the heart into the systemic and pulmonary circuits, which is crucial to prevent irreversible brain damage due to lack of blood flow. It's important to follow these CPR standards, as improper hand placement or excessive force can cause serious injuries, such as broken ribs or damage to internal organs like the liver.
