During CPR, external chest compression of an adult male should be how many cm?

2-3cm
4-5cm
5-6cm
6-7cm

The correct answer is: 4-5cm

During CPR, it is recommended to compress the chest of an adult male between 4-5cm. Options A and C (2-3cm and 5-6cm respectively) are too shallow and may not provide sufficient blood flow to the heart and brain. Option D (6-7cm) is too deep and may cause rib fractures or damage to internal organs. Therefore, option B (4-5cm) is the most appropriate depth for chest compressions during CPR on an adult male.
