He suffers a jagged tear of the skin of his nether regions caused by both shear and tensile forces of contact with the bike on the way down. This tear is BEST described as:
Explanation
Answer: C - A jagged tear of the skin caused by both shear and tensile forces is best described as a laceration. An incision, in contrast, is a clean cut caused from a tensile force alone, typically a sharp edge. A puncture is a penetration of the skin by an object and an abrasion is more of a surface injury, a “scraping” of the tissue. Irrespective of the type of skin injury, the area should be cleaned with water and a dry dressing applied. Pressure should be applied if the dressing is becoming saturated with blood.
