What is the difference between a closed wound and an open wound?

• A. A closed wound bleeds heavily; an open wound does not.
• B. A closed wound heals instantly.
• C. A closed wound affects only the skin.
• D. A closed wound has no break in the skin; an open wound has a break in the skin or mucous membranes.

Answer: (D)

The main idea is whether the surface barrier is broken. A closed wound keeps the skin and mucous membranes intact, with any damage happening beneath the surface—think bruising, swelling, or internal tissue injury without an open opening. An open wound, on the other hand, has a break in the skin or mucous membranes, so tissue is exposed, there may be visible bleeding, and contamination is more of a concern. That’s why the correct statement says a closed wound has no break in the skin and an open wound does have a break in the skin or mucous membranes. The other options aren’t the defining feature: bleeding can occur in either type, healing isn’t instant for any wound, and a closed wound isn’t limited to the skin alone or necessarily superficial.
