What is the purpose of a wound drain?

A wound drain is specifically designed to facilitate the removal of fluids, such as blood, pus, or other secretions, that can accumulate at the site of a wound. The presence of these fluids can create a conducive environment for infection and delay the healing process. By effectively draining these secretions, the wound drain helps promote a healthier environment that supports the body's natural healing mechanisms, preventing complications and enhancing recovery. This action is critical in ensuring that the wound can heal properly without obstruction or infection caused by excess fluid buildup.

The other options do not capture the primary function of a wound drain in the context of patient care.
