Which of the following methods can be used to control bleeding?

Elevating the affected area is an effective method for controlling bleeding because it utilizes gravity to reduce blood flow to the injured site. By raising the wound above the level of the heart, this technique can help decrease the pressure in the blood vessels supplying the area, which may slow the bleeding. Elevation is often recommended in conjunction with other bleeding control measures, such as applying direct pressure to the wound.

While cold compresses can temporarily constrict blood vessels and provide pain relief, they are not the primary method for managing active bleeding, especially if they are not applied correctly. Applying ice directly can also lead to tissue damage and does not effectively address bleeding on its own. Heat has the opposite effect by promoting blood flow, which could worsen bleeding, making it an inappropriate method for controlling hemorrhage.
