Wound Concepts

Question 1

Dermis

Answer 1

Lower layer

Question 2

Full thickness would

Answer 2

Wound that extends down into dermis

Question 3

Partial thickness wound

Answer 3

A wound limited to the epidermis

Question 4

Definition of wound

Answer 4

Disruption of the integrity and function of tissues in the body

-not all wounds are created equal

Question 5

Open

Answer 5

Wound that involves a break in skin mucous membrane

Surgical wound

Question 6

Closed wound

Answer 6

Wound that involves break but doesn’t come to surface

fracture

Question 7

Acute wound

Answer 7

Proceeds through the timely repairs, results in restoration of anatomical function and integrity

Question 8

Chronic wound

Answer 8

Wound doesn’t orderly heal itself, and may not return to proper anatomical function normality

(Bed sore)

Question 9

Intentional

Answer 9

Meant to have this wound occur (surgical)

Question 10

Unintentional

Answer 10

Wound happened unexpectedly

Question 11

Superficial

Answer 11

Involves only epidermal layer of skin(abrasion)

Question 12

Penetrating

Answer 12

Break in the epidermal layer as well as the dermis and could even go deeper and involve an organ

Question 13

Perforating

Answer 13

A foreign object enters and exits an internal organ

Question 14

Clean

Answer 14

No pathogenic organisms

-heals most quickly

Question 15

Clean contaminated

Answer 15

The wound was made under aseptic conditions, but went into cavity that usually harbors microorganisms

Question 16

Contaminated

Answer 16

Exists under conditions in which the presents if microorganisms are likely

Question 17

Infected

Answer 17

We know that bacterial microorganisms are in the wound and have over 100,000 microorganisms per gram of tissue

Question 18

Colonized

Answer 18

A wound that contains Microorganisms and the microorganisms are growing in the wound (MRSA)

Question 19

Laceration

Answer 19

The tearing of tissue, typically with some irregular edges

Question 20

Abrasion

Answer 20

A wound that typically results from a fall

Skinned knees

Question 21

Contusion

Answer 21

Closed wound(hematoma) usually caused by a blow from a blunt object

Question 22

Primary intention healing

Answer 22

Indication that there was little or no tissue loss and they will suture things together resulting in little to no scaring

• deceased risk for infection
• heals fairly quickly
• less likely to scar

Question 23

Secondary Intention healing

Answer 23

Occurs when there has been tissue lost

• wound cannot typically be sutured shut
• body has to granulate to heal wound
• epithelium finally grows over and leaves scar

Question 24

Stages of normal wound healing

Answer 24

1. Inflammatory
2. proliferative or regenerative
3. Maturation of remodeling h

Question 25

Inflammatory phase

Answer 25

-controls bleeding -delivery of blood and cells to injured area -forms epithelial cells at injured site Lasts up to 3-5 days

Question 26

Proliferative or regenerative phase

Answer 26

- begins with appearance of new blood vessels - regenerate and fill wound with new connective tissue - granulation tissue is formed - Lasts 3-24 days - eventually closes top of wound

Question 27

Maturation or remodeling phase

Answer 27

- Collagen tissue increases in strength - scar has fewer pigmented cells and may have lighter skin tone - can take as long as a year - keloid: overgrowth of tissue

Question 28

Serous

Answer 28

Clear in color

Question 29

Purulent

Answer 29

Puss,tan,brown, white associated with a foul odor

Question 30

Serosanginous

Answer 30

Bright pinky color, serous and sanguineous together

Question 31

Sanguineous

Answer 31

Active bleeding or darker in color

Question 32

Complications of wound healing

Answer 32

``` Hemorrhage Infection Dehiscence Evisceration Fistula Delayed wound healing ```

Question 33

Infection

Answer 33

Purulent drainage 100,000 microorganisms Foul odor

Question 34

Dehiscence

Answer 34

- the wound fails to heal properly and the skin tissue separates - adipose tissue has a harder time healing, leaving obese patients at high risk

Question 35

Evisceration

Answer 35

A total separation of the wound layers and a protrusion of the visceral organs -if this happens place normal saline on it to keep it moist

Question 36

Fistula

Answer 36

Abnormal passageway between two organs, or organ passing on outside of body

Question 37

Epidermis

Answer 37

Upper layer
