25
Moisture-associated skin damage (MASD) is a type of what?
Dermatitis
26
How do chronic wounds develop?
They develop over time because of a disruption in the wound healing process or because of alterations in blood flow
27
A chronic wound is what kind of wound?
A non-healing wound
28
What does tunneling mean in skin terminology?
Narrow channel or passage extending in any direction from the base of the wound
29
Shearing meaning?
Force parallel to the surface of the skin
30
What is it called whenever the skin and muscles are pulled in opposite directions?
Shear forces
31
What is hypoperfusion?
Low oxygen levels due to poor blood circulation
32
What scale is used to check someone’s risk for alterations in tissue integrity?
Braden scale
33
Undermining meaning?
An open area extending under skin along the edge of a wound
34
What does benchmarking mean?
Comparing results and outcomes to other sources of similarly retrieved data

Full-thickness skin loss
39
What is the fourth stage of pressure injury?
Full-thickness skin and tissue loss
40
What is a unstageable pressure injury?
Obscured full-thickness skin and tissue loss injury
41
Slough definition?
Yellow, stringy nonviable tissue found in the base of the wound
42
Eschar definition?
Hard nonviable black/brown tissue found in the wound bed
43
Deep tissue pressure injury (DTPI) meaning?
Persistent nonblanchable pressure injury that can appear as a maroon, deep red, or purple color
44
What is a mucosal membrane pressure injury caused by?
The insertion or placement of a foreign device
45
Debridement meaning?
Surgically removing dead tissue or other debris that can cause infection
46
What is negative pressure injury therapy used to assist?
The healing and closing of large wounds by reducing edema around the wound and increasing granulation tissue formation
47
Hematoma meaning?
Accumulation of blood in the body (blood pooling in tissues)
48
Sedona meaning?
Accumulation of serous fluid
49
What’s a Penrose drain?
A flat, pliable passive drain that uses gravity to drain accumulated fluids
50
What’s a Portable Wound Bulb Suction Device?
An active, closed system drain that uses negative suction to drain fluid from the wound
51
What’s Large Bottle Drainage?
If a large amount of fluid is expected, a higher-pressure, large bottle is used
52
What’s a circular portable wound suction device?
A special type of wound drainage system that is designed to continuously suction drainage from a wound by providing a low vacuum pressure
53
Vasoconstriction meaning?
Narrowing of blood vessels due to acute blood loss, pain, and/or low body temp
54
How many types of wound healing are there?
3
55
When does primary healing occur?
Occurs in clean lacerations and surgical incisions closed with skin adhesives or sutures
56
What type of wound healing is fastest?
Primary healing
57
When does secondary healing occur?
When the wound is left open to heal and granulation tissue forms from the bottom up in the wound bed
58
When is delayed primary closure?
When the wound is left open for 5 to 10 days before it’s closed with sutures
59
When should delayed primary closure be used and why?
To decrease the risk the risk of infection. Used when the site isn’t considered clean at the time the injury occurred
60
What are some of the main essential nutrients for wound healing and tissue strengthening?
Protein, omega-3 and omega-6 fatty acids, and vitamins A and C
61
If a wound infection is suspected, what do you do to figure out if it is or not?
You do a wound culture collection
62
What kind of solution is used to rinse a wound when doing a wound culture inspection?
0.9% sodium solution
63
Why is 0.9% sodium chloride used when collecting a wound culture?
To prevent normal skin micro-organisms from contaminating the culture
64
Dehiscence meaning?
Complete/partial separation of the suture line and underlying tissues. Occurs when a wound fails to heal properly
65
Evisceration meaning?
Protrusion of internal organs through a surgical wound which has dehisced or opened
66
Does a client with a Braden scale score of 23 have a higher risk of a tissue integrity issue than a client with a score of 9?
The higher the score, the less at risk you are for running into a tissue integrity issue
67
How long does it typically take before you can remove staples?
A week or two
68
What kind of wound dressing needs a secondary reinforcement?
An alginate dressing
69
What kind of wound dressing can be used to combat wounds with necrotized tissues and eschars?
Hydrogel
70
High-Fowler’s position has a downside. What’s the downside?
It increases the risk for shearing and alterations in skin integrity
71
Is an increased blood glucose level a sign of sepsis?
Yes
72
What kind of wound dressing is best used for covering superficial wounds that have minimal exudate?
A transparent film
