Compression therapy directly addresses the underlying pathophysiology by countering venous hypertension, improving venous return, and reducing edema that impairs wound healing.

Hemoglobin is the iron-containing protein found within red blood cells. It is responsible for binding to and transporting oxygen from the lungs to the body's tissues. The iron component of hemoglobin is also what gives red blood cells and blood its characteristic red color.

Epithelialization is the process by which epithelial cells migrate across the wound surface to restore the protective skin barrier, occurring as the final step of healing.

A hematoma is a localized collection of blood outside of blood vessels, typically clotted, within tissues or organs, often resulting from trauma or surgery. It forms when blood escapes from damaged vessels and accumulates, appearing as a bruise or swelling, and is distinct from conditions like cellulitis or evisceration.

Talcum powder should be avoided in areas prone to friction and pressure ulcers. It can clump, absorb moisture, and create abrasive particles that increase friction and shear forces on the skin. This can irritate the skin and contribute to skin breakdown, rather than preventing pressure ulcer formation.

Alginate dressings are highly absorbent, making them the best choice for deep, highly exudative wounds, especially those with significant drainage from tumor necrosis. Made from seaweed, alginates form a gel upon contact with wound exudate, which helps to manage moisture, promote autolytic debridement, and conform to the wound bed, creating an optimal healing environment.
