18
Q

What kind of diet should a patient with wounds be on?

Study These Flashcards
A

-High protein, carbohydrates, & vitamins w/ moderate fat intake

19
Q

What are the nutrition labs?

Study These Flashcards
A

Albumin & Prealbumin levels

20
Q

Woven guaze (sponges)

Study These Flashcards
A

absorb exudate

21
Q

Non-adherent material

Study These Flashcards
A

Doesn’t stick to wound bed

22
Q

Wet-to-Dry

Study These Flashcards
A

-Used to mechanically debride a wound until granulation tissue starts to form
-A moist wound bed supports movement of epithelial cells and helps facilitate wound closure
-Help pull of dead skin cells

23
Q

Self-adhesive, transparent: Ex. Tegaderm

Study These Flashcards
A

Careful bc they will pull off good skin

24
Q

Hydrocolloid wound dressing

Study These Flashcards
A

Occlusive dressing that swells in presence of exudate
Ex. Duoderm
-Helps maintain moist environment but also kind of pull away excessive drainage and also protect it
-Replace in 3 days

25
Hydrogel wound dressing
Mostly water, gels after contact with exudate, promotes autolytic debridement, rehydrates and fills dead space -May need secondary occlusive dressing -Provides moist wound bed and can reduce pain -Prevents breakdown in high pressure area -Need HCP Order
26
What type of wound would you use a hydrogel dressing on?
Infected, deep wounds or necrotic tissue
27
What type of wound would you not use a hydrogel dressing on?
Wound with alot of drainage
28
Aliginates wound dressing
Nonadherent dressing that conform to wounds shape, and absorb exudate
29
Collagen
Powders, paste, granules, gels -Stop bleeding and promote healing
30
Vacuum-assisted closure system: Wound Vac
Use of foam strips into the wound bed with occlusive dressing - creates negative pressure (help increase tissue perfusion to area) Need HCP order to apply, when to change, and what to set pressure to Usually change ever 3 days/ Becomes part of assessment
31
A wound Vac helps with
-Tissue generation -Decrease swelling -Enhance healing in moist, protective environment -Wounds not healing naturally, dehiscent wounds, or perineal wounds
32
Complications of wound healing
1. Adhesions 2. Contractions 3. Hemorrhage 4. Dehiscence 5. Evisceration 6. Fistula formation 7. Infection 8. Excessive granulation tissue 9. Keloid formation
33
Hemorrhage is caused by
-Clot dislodgement, slipped suture, or blood vessel damage -Greatest risk 24-48 hrs after injury/surgery -Can be Emergency: apply pressure dressing, notify HCP, and monitor vital signs (may need fluids to increase BP or blood transfusion)
34
Internal bleeding may present with
swelling, distention in area, and may cause sanguineous drainage (& initially, subtle change in V.S.)- Increase HR & BP
35
What is a Hematoma?
a local area of blood collection that appears as red or blue bruise
36
What is Dehiscence?
Partial or total rupture (seperation) of a sutured wound, usually with a separation of underlying skin layers -Failure of proper wound healing -Happens 2-11 days after surgery before collagen formation -Usually do small wet to dry dressing
37
What is Evisceration?
A dehiscence that involves the protrusion of visceral organs through wound opening
38
Manifestations of Evisceration
-Significant increase in flow of serosanguinous fluid on the wound dressing -Straining -Sudden change or 'Pop' or 'Giving way'
39
Risk factors for dehiscence and evisceration
-Chronic disease -Advanced age -Obesity -Invasive abdominal cancer -Vomiting -Excessive straining, coughing, sneezing -Dehydration, malnutrition -Ineffective suturing -Abdominal surgery -Infection
40
Dehiscence/ Evisceration Nursing Management
-Notify HCP Immediately due to surgical intervention -Stay w/ pt -Cover wound and any protruding organs with sterile towels or sterile dressing soaked with normal saline -Do not attempt to reinsert organs -Maintain calm environment -Position pt supine with hips and knees bent to decrease abdominal tension -Keep pt NPO
41
Risk factors of infection and surgical wounds
-Age extremes -Immune suppression -Impaired circulation/ oxygenation -Wound Condition & nature -Malnutrition -Chronic Disease -Poor wound management
42
Manifestations of infection and surgical wounds
2-11 days after injury or surgery -Pain -Redness, edema, & purulent drainage (around wound) -Fever & Chills -Odor -Increased pulse & RR -Increased WBC
43
Nursing interventions for wound infection
-Prevent infection using aseptic technique with dressing changes -Provide optimal nutrition -Provide adequate rest -Administer antibiotic therapy after culture and sensitivity test
