Massachusetts Wastewater Practice Exam

Which procedure is considered the only accepted method to control bleeding in a first aid situation?

1. Use of pressure points on major arteries.

2. Elevation: raise the wound higher than the heart.

3. Tourniquets.

4. Direct pressure.

The correct answer is: Direct pressure.

Direct pressure is the only accepted method to effectively control bleeding in a first aid situation. This technique involves applying firm, consistent pressure directly to the wound, which helps to slow down or stop the flow of blood. By controlling the bleeding at the source, direct pressure not only minimizes blood loss but also encourages clot formation, promoting healing. While other methods such as pressure points, elevation, and tourniquets can be useful in specific scenarios or as adjuncts to direct pressure, they are not the primary or most effective means of managing bleeding in a standard first aid context. Pressure points require knowledge of anatomy and may not always effectively stop bleeding, especially if a major artery is not involved. Elevation can assist in reducing blood flow, but it is not sufficient on its own to stop bleeding. Tourniquets are generally used as a last resort for life-threatening situations and should only be applied by trained individuals. Thus, the focus on direct pressure as the primary method underscores its importance in first aid protocols.
