Explanation:

Question 17

• abrasion: The prefix "ab-" means away, and "rasion" relates to scraping. So abrasion is the process of scraping away the skin (mechanical or injury - related).
• contusion: Refers to a bruise, caused by blunt force trauma, not scraping.
• laceration: Is a tear or jagged wound, not scraping.
• gangrene: Is the death of tissue, often due to lack of blood supply or infection, not scraping.

The Middle Dutch word "bluyster" from which "blister" is derived means a swelling. Redness is related to erythema, cracking is related to terms like "fissure", and fluid - filled is a characteristic of a blister but not the meaning of the Middle Dutch root.

Answer:

A. ab/ras/ion
