Question

Which of the following is not a skin injury?

• A. Abrasion
• B. Laceration
• C. Incision
• D. Sprain

Answer 1

The Correct Option is D

The question presented is to identify which option is not associated with a skin injury. To address this, let's define each term in the context of injury classification: 

• Abrasion: This is an injury resulting from the scraping or wearing away of the skin. It is typically superficial and affects the skin's surface.
• Laceration: A laceration is a deep cut or tear in the skin or flesh, often caused by a sharp object or impact.
• Incision: An incision refers to a clean cut into the skin, usually made during surgical operations.
• Sprain: A sprain is an injury to a ligament, usually caused by a fall, twist, or blow to a joint. It does not involve the skin, but rather the connective tissues supporting the joints.

Based on these definitions, the correct answer to the question 'Which of the following is not a skin injury?' is Sprain.

Answer 2

A sprain is an injury that affects the ligaments, which are the tough, fibrous tissues connecting bones to other bones. It typically occurs when a joint is twisted or stretched beyond its normal range of motion, causing the ligaments to stretch or tear. Unlike cuts, bruises, or other injuries that affect the skin, a sprain does not involve any damage to the skin itself.

On the other hand, the injuries mentioned in the statement, which are skin injuries, directly affect the skin and its layers. These may include abrasions (scrapes), lacerations (cuts), and contusions (bruises). These injuries occur when external forces, such as sharp objects, impact, or friction, cause damage to the outer layer of the skin.

In summary, a sprain is an injury to the ligaments, not the skin, whereas other types of injuries typically affect the skin itself.
