What characterizes a patch?

Scab of dried exudate of body fluid, blood, or pus
Serous fluid trapped under skin greater than 0.5cm in diameter
Loose, stringy, nonviable tissue
Raised spot of color change less than 0.5cm in diameter

The correct answer is: Raised spot of color change less than 0.5cm in diameter

A patch is defined as a raised area characterized by a color change on the skin that measures greater than 0.5 cm in diameter. This distinction is important because it differentiates a patch from other skin lesions such as macules, which are flat and less than 0.5 cm. Patches can indicate various dermatological conditions and serve as important identifiers for skin evaluations. Their capacity to change color may signal underlying issues, including inflammation or reactions to allergens. Understanding this term is essential in wound care and assessment, as recognizing different skin characteristics can guide treatment options and interventions.
