Second Degree- Affects through deep epidermal layers, damage can reach upper dermis. Has blisters.
Third Degree- Complete destruction of the epidermis and the dermis.
Fourth Degree- The burn affects the underlying muscle and bone.
What is the rule of 9’s when working with a burn?
The body is made up of 11 areas = 9%
Head = 9%
Chest (front) = 9%
Abdomen (front) = 9%
Upper/mid/low back and buttocks = 18%
Each arm = 9% (front = 4.5%, back = 4.5%)
Groin = 1%
Each leg = 18% total (front = 9%, back = 9%)
Add all of the percentages to get the percent of the body burned.
List some types of wounds.
Pressure (ex. pressure of boney areas of the body against another surface causing a sore).
Shearing- skin stays put but body slides
Friction- Rubbing skin against another surface (irritated area appears as a blister)
Moisture- Occurs when a person lays in moisture for extended periods of time causing a sore.
Venous Stasis Ulcer vs. Arterial Ulcer- an inadequate amount of blood flow to extremities.
What are the classifications of a wound? Define them.
Stage 1: sores are not open wounds.
At stage 2: the skin breaks open, wears away, or forms an ulcer, which is usually tender and painful.
Stage 3: the sore gets worse and extends into the tissue beneath the skin, forming a small crater. Fat may show in the sore, but not muscle, tendon, or bone.
At stage 4: the pressure sore is very deep, reaching into muscle and bone and causing extensive damage. Damage to deeper tissues, tendons, and joints may occur.

What are the four chambers of the heart?
Right and Left ATRIA (upper)
Right and Left VENTRICLE (lower)
How does blood move through the heart?
Right Side of the Heart
Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart.
As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.
When the ventricle is full, the tricuspid valve shuts. This prevents blood from flowing backward into the atria while the ventricle contracts.
As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
Left Side of the Heart
The pulmonary vein empties oxygen-rich blood from the lungs into the left atrium of the heart.
As the atrium contracts, blood flows from your left atrium into your left ventricle through the open mitral valve.
When the ventricle is full, the mitral valve shuts. This prevents blood from flowing backward into the atrium while the ventricle contracts.
As the ventricle contracts, blood leaves the heart through the aortic valve, into the aorta and to the body.
