Burns

Question 10

Classification of Burns

Answer 10

Burn Depth
Burn Severity
Symptoms of Burn

Question 11

Doctors classify burns according to strict. The definitions classify the burn’s depth and the extent of tissue damage

Answer 11

Burn Depth

Question 12

Burns are classified as minor, moderate, or severe. The severity determines how they are predicted to heal and whether complications are likely. This determine the severity of the burn by its depth and by the percentage of the body surface that has partial-thickness or full-thickness burns.

Answer 12

Burn severity

Question 13

Vary with the burn’s depth

Answer 13

Symptoms of burn

Question 14

Burn depth

Answer 14

Superficial burns
Partial-thickness burns
Full-thickness burns

Question 15

Burn Severity

Answer 15

Minor burns
Moderate and severe burns

Question 16

Symptoms

Answer 16

Superficial burns
Partial-thickness burns
Full-thickness burns

Question 17

Type of burn depth
-burns are the most shallow (also called first-degree burns)
-they affect only the top layer of the skin (epidermis)

Answer 17

Superficial burns

Question 18

Type of Burn Depth
- also called second degree burns
- middle layer of the skin (dermis)
- involving both the superficial and the deep parts of the dermis

Answer 18

Partial-thickness burns

Question 19

Type of burn depth
- also called third-degree burns
- involve all three layers (epidermis, dermis, and fat layers)
- the sweat glands, hair follicles, and nerve endings are destroyed as well.

Answer 19

Full-thickness burns

Question 20

Type of burn severity
- all superficial burns as well as partial thickness burns that involve less than 10 percent of the body surface

Answer 20

Minor burns

Question 21

Type of burn severity
- burns involving the hands, feet, face, or genitals, partial-thickness burns involving more than 10 percent of the body surface area, and all full thickness burns involving more than 1 percent of the body

Answer 21

Moderate and severe burns

Question 22

Type of symptoms
- red, swollen, and painful.
- the burned area whitens (blanches) when lightly touched but does not develop blisters

Answer 22

Superficial burns

Question 23

Type of symptoms
-pink or red, swollen and extremely painful
-within 24 hours (often shortly after the burn), blisters usually develop that may ooze a clear fluid.
-the burned area may blanch when touched

Answer 23

Partial-thickness burns

Question 24

Type of symptoms
- usually are not painful because the nerves that sense pain have been destroyed
- the skin becomes leathery and may be white, black, or bright red
- the burned area does not blanch when touched
- hairs can easily be pulled from their roots without pain

Answer 24

Full thickness burns

Question 25

Estimating the extend of a burn

Answer 25

Head and neck (9%)
Trunk front and back (18% each)
Arm (9% each)
Genital area (1%)
Leg (18 % each)

Question 26

Usually superficial and do not cause complications

Answer 26

Minor burns

Question 27

Can cause serious complications due to extensive fluid loss and tissue damage

Answer 27

Severe burns and some moderate burns

Question 28

Complications of burns

Answer 28

-dehydration
-shock
-chemical imbalances
-destruction of muscle tissue
-infection
-eschars (crusty surface)
-hypothermia (body temp is low)

Question 29

-Major structural protein in our tissues
-its found in skin, hair, nails, tendons, cartilage, and bones

Answer 29

Collagen
