Q

How does pressure result in an ulcer forming?

A
  • If pressure over a capillary exceeds normal capillary pressure and the vessel is occluded (obstructed) for a prolnted time, tissue ischemia (shortage of blood supply/O2) occurs which can cause tissue death.

Q

What are the 4 types of wound drainage?

A
  1. Serous
  2. Sanguineous
  3. Serosanguineous
  4. Purulent
26
Q

Describe Serous wound drainage.

A
  • This type of drainage is plasma that’s thin, clear and watery
  • During the inflammatory stage, a small amount of this bloody leakage is natural.
  • When this type of exudate occurs during other wound healing stages, it may be an indicator that the wound bed has undergone trauma, such as during dressing changes, which can hinder healing.
27
Q

Describe Sanguineous wound drainage.

A

Drainage that is fresh blood and prevalent among deep wounds of full and partial thickness

28
Q

Describe Serosanguineous wound drainage

A
  • Leakage is thin and watery, and it’s pink in color (it can also be a darker red).
  • The pink tinge is the effect of red blood cells in the fluid, which is a sign that there is damage to the capillaries.
  • Such damage generally occurs during wound dressing changes and can disrupt the healing process.
29
Q

Describe Purulent wound drainage.

A
  • Wound appears milky
  • It’s generally gray, green or yellow
  • Most commonly thick in consistency, though some purulent exudate can be thin.
  • This may be a sign that the wound has an infection
30
Q

The first dressing change is done by…

A

the doctor

31
Q

If the doctor is delayed for the first dressing change and the current dressing is soaked, what action is the nurse permitted to take?

A

Reinforce with a new bandage on top of the old.

32
Q

What are five types of complications?

A
  1. Hemorrhage
  2. Hematoma
  3. Infection
  4. Dehiscence
  5. Evisceration
33
Q

Define “hemorrhage”

A

An escape of blood from a ruptured blood vessel, especially when profuse.

34
Q

Define “hematoma”

A
  • a solid swelling of clotted blood within the tissues.
  • bruising
35
Q

Define “infection”

A
  • a localized defect or excavation of the skin or underlying soft tissue
  • pathogenic organisms have invaded into viable tissue surrounding the wound.
  • Infection of the wound triggers the body’s immune response, causing inflammation and tissue damage
  • slows the healing process.
36
Q

Define “Dehiscence”

A
  • splitting of the wound
  • healing would edges become non-approximated
  • surgical wound reoopens
37
Q

Define “Evisceration”

A
  • Occurs when an abdominal wound opens and interal organs prodrude
38
Q

What are the factors to address with an evisceration?

A
  • Emergent
  • Cover with sterile gauge
  • Rush back to OR
  • At risk for sepsis
39
Q

The Braden Scale is used for…

A

predicting pressure ulcer risk

40
Q

What are the six categories used in the Braden Scale Score?

A
  1. Sensory perception
  2. Moisture
  3. Activity
  4. Mobiility
  5. Nutrition
  6. Friction and shear
41
Q

A Braden Scale Score of 23 indicates what level of risk for developing a pressure ulcer?

A

No Risk

42
Q

A Braden Scale Score of 15-18 indicates what level of risk for developing a pressure ulcer?

A

At risk

43
Q

A Braden Scale Score of 13-14 indicates what level of risk for developing a pressure ulcer?

A

Moderate Risk

44
Q

A Braden Scale Score of 10-12 indicates what level of risk for developing a pressure ulcer?

A

High Risk

45
Q

A Braden Scale Score of ≤ 9 indicates what level of risk for developing a pressure ulcer?

A

Very High Risk

46
Q

How do we check for overall tissue perfusion?

A
  • At the periferal pulse
  • If pulse week, perfusion will be low
  • If pulse strong, perfusion will be high
47
Q

On the Braden Scale, the higher the number the _____ the risk.

A

lower

48
Q

What are four other factors (not on the Braden Scale) that can influence pressure ulcer formation?

A
  1. Tissue perfusion
  2. Infection
  3. Age
  4. Psychsocial impact of wounds
49
Q

What is the Jackson-Pratt Drainage Device?

A

A closed-suction medical device that is commonly used as a post-operative drain for collecting bodily fluids from surgical sites.

50
Q

What are the nursing responsibilities regarding the JP Drainage Device?

A
  • Measure output
  • Assess T.A.C.O
  • Check tubing to make sure its not kinked or dislodged
  • If its coming apart call MD
51
Q

What are the three types of Implementation?

A
  1. Independent
  2. Dependent
  3. Collaborative
52
Q

What is the female external catheter called?

A

Purewick

53
Q

What is the male exteral catheter called?

A

Condom catheter or Texas catheter

54
Q

How does the Nurse know what kind of dressing to use on a wound?

A

The doctor will indicate

55
Q

What are five types of wound dressings?

A
  1. Dry/Moist
  2. Film Dressing
  3. Hydrocolloid
  4. Hydrogel
  5. Vacuum assisted closure (VAC)
56
Q

Describe a film dressing.

What stage ulcer is it used for?

A
  • transparent to permit viewing of wound without opening it
  • adheres to undamaged skin
  • does not require secondary dressing
  • traps moisture over wound
  • Used for stage I and II ulcers
57
Q

Describe a hydrocolloid dressing.

What stage ulcer is it used for?

A
  • Wafer dressing
  • protects wound from surface contamination
  • Used for Stage II and III ulcers
58
Q

Describe a hydrogel dressing.

What stage ulcer is it used for?

A
  • gel-based wound care dressing
  • protects and provides a moist wound-healing environment
  • helps remove dead tissue from the wound bed during the healing process.
  • used for stage III and IV ulcers
59
Q

How does a VAC work?

A
  • uses a negative pressure to support healing
60
Q

What are the Nurse responsibilities when a VAC is in use?

A
  • Tell patient not to pull on it
