Which of the following techniques should a medical assistant use when bandaging a wound with a roller bandage?

When bandaging a wound with a roller bandage, wrapping the wound from distal to proximal is the appropriate technique. This method is important because it promotes venous return, which helps reduce swelling and improve circulation to the area. By starting at the farthest point from the heart and moving towards it, you help ensure that blood flow is not impeded.

This technique also provides better support and compression to the injury, facilitating healing and minimizing the risk of complications. Proper wrapping techniques, such as maintaining a consistent tension without cutting off circulation, are also crucial in this context.

Other options include wrapping from proximal to distal, which can impede blood flow and increase swelling. Applying multiple layers without overlapping would lead to an uneven distribution of pressure, which can be uncomfortable and ineffective. Finally, simply using adhesive tape to secure the bandage may not provide enough stability or be appropriate for all types of bandage applications, making it essential to wrap securely and safely according to standard practices.
