What should you avoid doing when bandaging a wound?

Tying the knot on top of the bandage should be avoided because it can create additional pressure on the wound and potentially impede circulation. When applying a bandage, it is essential to ensure that the knot is secured in a manner that does not interfere with blood flow and allows for proper healing. By positioning the knot on the side or underneath the bandage, you minimize the risk of causing discomfort or further injury to the affected area.

In contrast, applying direct pressure is crucial for controlling bleeding, using sterile materials is fundamental for preventing infection, and wrapping the bandage tightly may be necessary to secure it in place, provided it is not so tight as to cut off circulation. All these practices are aligned with proper first aid techniques, while ensuring the knot placement is optimal for patient comfort and care.
