Ans: B
A closed wound results from a blow, force, or strain caused by trauma (such as a fall, an assault, or a motor vehicle crash). The skin surface is not broken, but soft tissue is damaged, and internal injury and hemorrhage may occur. Examples include ecchymosis and hematomas. An open wound occurs from intentional or unintentional trauma. The skin surface is broken, providing a portal of entry for microorganisms. Bleeding, tissue damage, and increased risk for infection and delayed healing may accompany open wounds. Examples include incisions and abrasions.
