Q

What is the difference between evisceration and dehiscence?

A

Dehiscence involves separation of the tissues (re-opening of the wound). Evisceration occurs when the visceral tissues protrude from the opening.

29
What type of dressing allows the wound to be visualized, and is impermeable to bacteria and other contaminants?
Transparent Dressings
30
What type of dressing is typically used for wounds healing by primary intention following surgery?
Gauze Dressings
31
What must be done to gauze dressings if the dressing adheres to a wound?
Gauze must be moistened if it adheres to wound.
32
What type of dressing provides autolytic debridement of necrotic wounds?
Hydrocolloid dressings. Maintains a moist environment . Used for venous stasis arterial and pressure ulcers can be left in place three to five days.
33
What type of dressing has cooling and soothing properites that make it useful on burns?
Hydrogel dressings. Water based non adherent dressing promotes wound debridement rehydrates the wound.
34
Name the three types of drains.
Penrose, Jackson-Pratt, Hemovac.
35
What drain is considered an open drainage system?
Penrose drain.
36
What drains are considered closed drainage systems?
Jackson-Pratt & Hemovac.
37
What primary action is used in closed drainage systems?
Suction/Vacuum.
38
What primary action is used in an open drainage system?
Gravity.
39
When changing a dressing and cleaning a wound with a drain, give the order of what areas are cleaned.
1) Center of incision site. 2) Side of incision away from drain. 3) Side of incision near the drain 4) Skin surrounding the drain
40
How can items be added to the sterile field?
Carefully grasping the edge of the closed package, peel it open, and items dropped onto the sterile field.
41
How is the sterile field opened?
Away from the nurse first. Sides are second, making sure not to pass over the sterile field. Toward the nurse last.
42
What signs and symptoms are important to record and report regarding wound care?
Status of dressing. Integrity of suture line. Changes in skin color. Presence and character of drainage.
43
When are W/D dressings used?
Open wounds requiring debridement.
44
What types of wounds is the wound vac useful for?
Stage III & IV pressure ulcers, skin flaps, chronic surgical wounds, and traumatic wounds.
45
When is the use of heat contraindicated?
``` 24 hours after traumatic injury. Active hemorrhage. Non inflammatory edema. Localized malignant tumors. Redness/Blisters. ```
46
When is the use of cold contraindicated?
Open wounds. Impaired circulation. Allergy/Hypersensitivity to cold.
47
Give an example of dry heat.
Hot water bottle, heating pad.
48
Hive an example of moist heat.
Soaks, compresses, hot packs.
49
What are the primary principles for applying a bandage?
``` Position in anatomical alignment. Separate skin surfaces. Pad bony prominences. Observe medical asepsis (Clean technique) Apply equal tension. ```
50
What type of turn is used to immobilize a joint?
Figure-8.
51
A dressing contains a large amount of brightly colored red exudate. How would the nurse describe the exudate?
Sanguineous exudate.
52
A dressing contains only clear watery drainage. How would the nurse describe the drainage?
Serous exudate.
53
A dressing is observed to have green tinged exudate. How would the nurse describe the exudate?
Green purulent exudate.
54
A dressing is observed to have light pink drainage. How would the nurse describe the drainage?
Serosanguineous drainage.
55
A nurse who washes hands and puts on clean gloves when administering a bolus feeding is using what type of technique?
Medical Asepsis (Clean Technique)
56
When changing a dressing, the nurse uses what technique to prevent introduction of microorganisms into the wound?
Surgical Asepsis (Sterile Technique)
57
When preparing to change a dressing, the nurse notes the sterile solution bottle was opened 12 hours ago on the previous shift. If the solution still usable/sterile?
Yes. Sterile solutions are only good for 24 hours after opening.
58
When changing a dressing and assessing the wound, what four things should the nurse record and report?
1) Status of dressing. 2) Integrity of suture line. 3) Changes in skin color 4) Presence and character of drainage.
59
A patient with a chronic stage 3/4 surgical wound may be a candidate for what type of wound treatment?
Wound Vac
60
A patient asks how the wound vac is going to help the wound heal. How would the nurse respond?
A wound vac improves tissue perfusion, removes drainage, and mechanically debrides tissue.
61
Why are bandages applies distal to proximal?
Support circulation, Risk of edema is minimalized.
62
When assessing for the tightness of a bandage, what should the nurse look for?
Color and temperature of skin, capillary refill, and patient comfort.
