Painful, acute, accidental wounds, largely preventable.

A. Skin tears are painful, acute, accidental wounds often caused by friction or shear, especially in older adults with fragile skin. They are largely preventable with proper skin care, handling techniques, and protection. B. Pressure injuries result from prolonged pressure over bony areas and are typically chronic rather than acute, though also preventable. C. Xerosis refers to dry skin, not an acute wound. It can contribute to skin vulnerability but is not a wound itself. D. Purpura are purple discolorations due to small blood vessel bleeding under the skin and are not painful wounds, nor are they accidental or acute in nature.
