Question 1

_________________ are defined as those in which a force is applied to the surface of the body or the body comes into contact with a surface, causing an injury.&#10;A) Blunt force injuries&#10;B) Sharp force injuries&#10;C) Abrasions&#10;D) Lacerations

Accepted Answer

Blunt force injuries are caused by a force applied to the surface of a body or when a body comes into contact with a surface, resulting in an injury. Sharp force injuries are caused by a sharp object, abrasions are superficial injuries to the surface of the skin, and lacerations are caused by a blunt or sharp object that tears the skin. Therefore, choice A best fits the definition provided.

Question 2

An ______________ is a scrape on the skin causing a loss of the superficial layers of the skin.&#10;A) Embolus&#10;B) Abrasion&#10;C) Incision&#10;D) Avulsion

Accepted Answer

An abrasion is a scrape on the skin that causes a loss of the superficial layers of the skin. An embolus is a clot that travels through the bloodstream and can cause blockages. An incision is a cut made with a surgical instrument. An avulsion is a tearing away of a body part, such as a finger or toe.

Question 3

A contusion is commonly known as a(n) ______________.&#10;A) Embolus&#10;B) Avulsion&#10;C) Abrasion&#10;D) Bruise

Accepted Answer

A contusion is a type of injury that involves bleeding beneath the skin, resulting in a bruise.

Question 4

A(n) ________________is created by a force being applied to the skin, causing rupture of the small blood vessels and bleeding into the tissue under the skin surface.&#10;A) Contusion&#10;B) Abrasion&#10;C) Laceration&#10;D) Avulsion

Accepted Answer

A contusion is a type of injury where force causes the small blood vessels under the skin surface to rupture and bleed into the surrounding tissue. This results in a bruise, which may take on a range of colors as the blood is reabsorbed by the body over time. Abrasions are caused by friction or rubbing of the skin, lacerations occur when the skin is cut or torn, and avulsions involve the tearing away of tissue from the body.

Question 5

________________are actual tears of the skin that result when the force being applied exceeds its elastic ability to stretch, causing it to tear.&#10;A) Abrasions&#10;B) Avulsions&#10;C) Lacerations&#10;D) Contusions

Accepted Answer

Lacerations are actual tears of the skin that occur when the force being applied to the skin exceeds its elastic ability to stretch, causing it to tear. Abrasions are superficial injuries that result from scraping or rubbing of the skin surface. Avulsions are injuries that result in the separation of a flap of skin from the underlying tissue. Contusions are injuries that involve bleeding in the underlying tissues without breaking the skin.

Question 6

A(n) _________ is a subtype of laceration in which the tear has created a flap of skin that is able to be lifted from the underlying muscle or bone.&#10;A) Abrasion&#10;B) Incision&#10;C) Contusion&#10;D) Avulsion

Accepted Answer

An avulsion is a tear in which the skin has been partially or completely torn away from the underlying muscle or bone, creating a flap of skin that can be lifted up. This is different from an abrasion, which is a scrape or rub on the skin's surface, an incision, which is a smooth cut made by a sharp object, or a contusion, which is a bruise that results from blunt force trauma.

Question 7

___________is a term used to describe an occurrence in skull injuries when the force applied causes a pocket to form under the skin but does not create a flap, as seen with an avulsion.&#10;A) Undermining&#10;B) Laceration&#10;C) Abrasion&#10;D) Contusion

Accepted Answer

Undermining refers to the formation of a pocket of damaged tissue under the intact skin, often seen in head injuries where there is not enough force to cause a flap of skin to detach. Laceration refers to a cut or tear in the skin, abrasion refers to superficial damage to the skin caused by scraping or rubbing, and contusion refers to a bruise caused by blunt force.

Question 8

Abrasions can be patterned or have characteristic appearances due to the objects creating them.

Accepted Answer

This is true. Abrasions can have patterned or characteristic appearances based on the object that caused them. For example, an abrasion caused by a road surface might have a rough or scraped appearance, while an abrasion caused by a sharp object might have a more distinct or patterned appearance.

Question 9

&#34;Road rash&#34; is also known as brush burn abrasion.

Accepted Answer

Road rash is a type of abrasion that occurs from sliding on a rough surface such as pavement. It is also known as brush burn abrasion.

Question 10

As an abrasion heals, the edge of the wound tends to dry and become heaped up.

Accepted Answer

This is true as the scabbing process creates a protective layer over the wound which can cause the edges to become heaped up as the new skin grows underneath.
