Why should old bandages not be removed when new ones are applied?

The rationale for not removing old bandages when applying new ones primarily centers around the potential disruption of the clotting process. When a wound has begun to clot, the old bandage may actually be adhering to the clot that has formed. If the old bandage is removed, it can tear away the clot, leading to renewed bleeding and possibly setting back the healing process.

By keeping the old bandage in place, new bandages can be layered on top to provide support and help manage any further bleeding while minimizing the risk of dislodging the clot. This method allows for continued care of the injury without compromising the natural healing mechanisms already in play.

The other options, while they may touch on some aspects of wound care, do not directly address the crucial concern of preserving the clotting process, which is vital for effective wound management.
