Question

When applying direct pressure, it is important to do which of the following? Select all that apply.

Press softly.
Press hard.
Press directly over the wound.
Press 2 to 3 inches above the wound.
Press 2 to 3 inches below the wound.

Answer 1

When applying direct pressure to a wound, it is important to press directly over the wound with a firm and hard pressure to control bleeding. Pressing softly or around the wound is less effective.

Step-by-step explanation:

When applying direct pressure to a wound, it is important to:

• Press hard and firmly to help control bleeding.
• Press directly over the wound to effectively apply pressure to the site of bleeding.

It is not recommended to press softly, as it may not be sufficient to stop the bleeding. Additionally, pressing 2 to 3 inches above or below the wound is not effective for direct pressure on the wound itself. In case of severe bleeding, direct pressure over the wound along with elevation and calling for emergency services is the correct protocol. Understanding the principle of pressure, which is force per unit area, helps explain why effective direct pressure is crucial in a bleeding emergency. A smaller surface area, just like the sharp edge of a knife, will exert more pressure with the same amount of force, as seen in medical applications like hypodermic needles or when cutting with a sharp object.
