How many pressure points can be used to temporarily control bleeding by applying hand pressure?

The correct choice reflects the understanding that there are 22 pressure points in the human body that can be utilized to effectively control bleeding through the application of hand pressure. These pressure points are strategically located where major arteries are positioned close to the skin, allowing for effective compression against the underlying bone. When pressure is applied to these points, it can significantly reduce blood flow to the area that is bleeding, thereby helping to stabilize the patient until further medical assistance can be rendered.

Mastering the use of these pressure points is essential for first responders and rescuers, ensuring they can act quickly and efficiently in emergency situations. Knowing the right locations and how to effectively apply pressure can make a substantial difference in managing traumatic injuries and preventing excessive blood loss.
