If you do not have a tourniquet but have access to roller bandages, how should they be applied after applying gauze?

Applying roller bandages firmly over the gauze is essential to maintain adequate pressure on a bleeding wound. This pressure helps to control the bleeding by facilitating clot formation and preventing blood from escaping the body. When applying the bandage, ensuring that it is snug but not so tight that it cuts off circulation is critical. The goal is to keep the gauze in place while effectively managing the wound.

Using a firm application also allows the bandage to stay secure during movement or in situations where the patient may need to be transported. The effectiveness of this technique becomes crucial in emergency scenarios where maintaining blood loss is a priority until professional medical assistance can be obtained.

The other options do not effectively manage the risk of severe blood loss, which is the primary concern when dealing with a significant wound.
