Q

What are 5 factors affecting skin integrity?

A
  1. Genetics and heredity: some people have thicker skin.
  2. Age: decrease in SQ fat, decreasing collagen, muscle atrophy
  3. Chronic illnesses and their treatments: cancer pts will have skin integrity issues.
  4. Medications: steroids cause tissue damage and bleeding under surface of skin (in elderly)
  5. Poor nutrition: metabolism, protein, fat. Reference: dying with a stage IV pressure ulcer.

Q

What are 7 risk factors for pressure ulcers?

A
  1. Advanced age
  2. Chronic mental conditions: ex if young in mental institute, may want to sit all day in same position. contact/pressure areas susceptible to skin breakdown.
  3. Poor lifting and transferring techniques; poor nursing lifting;
  4. Incorrect positioning: increased risk for skin ulcers: ex. leaning on arm rail. if on prednisone (steroid) increases risk.
  5. Hard support surfaces: when put in chair, put pillow on seat of chair if they going to be there a while.
  6. Incorrect application of pressure-relieving devices: ex. don’t use donut in right spot.
  7. tissue breakdown from urine and fecal incontinence

B. Sensitive skin that requires special bed linen.
C. A stage III pressure ulcer needing the appropriate dressing.
D. Blanching hyperemia, indicating the attempt by the body to overcome the ischemic episode.

A

D. Blanching hyperemia, indicating the attempt by the body to overcome the ischemic episode.

61
Q 
Which type of pressure ulcer is noted to have intact skin and may include changes in one or more of the following: skin temperature (warmth or coolness), tissue consistency (firm or soft), and/or pain?
A.	Stage I
B.	Stage II
C.	Stage III
D.	Stage IV
A

A. Stage I

62
Q

hen obtaining a wound culture to determine the presence of a wound infection, from where should the specimen be taken?
A. Necrotic tissue
B. Wound drainage
C. Drainage on the dressing
D. Wound after it has first been cleaned with normal saline

A

D. Wound after it has first been cleaned with normal saline
Drainage that has been present on the wound surface can contain bacteria from the skin, and the culture may not contain the true causative organisms of a wound infection. By cleaning the area before obtaining the culture, the skin flora is removed.

63
Q

After surgery the patient with a closed abdominal wound reports a sudden “pop” after coughing. When the nurse examines the surgical wound site, the sutures are open, and pieces of small bowel are noted at the bottom of the now-opened wound. Which corrective intervention should the nurse do first?
A. Allow the area to be exposed to air until all drainage has stopped
B. Place several cold packs over the area, protecting the skin around the wound
C. Cover the area with sterile, saline-soaked towels and immediately notify the surgical team; this is likely to indicate a wound evisceration
D. Cover the area with sterile gauze, place a tight binder over it, and ask the patient to remain in bed for 30 minutes because this is a minor opening in the surgical wound and should reseal quickly

A

C. Cover the area with sterile, saline-soaked towels and immediately notify the surgical team; this is likely to indicate a wound evisceration

64
Q

Which of the following describes a hydrocolloid dressing?
A. A seaweed derivative that is highly absorptive
B. Premoistened gauze placed over a granulating wound
C. A debriding enzyme that is used to remove necrotic tissue
D. A dressing that forms a gel that interacts with the wound surface

A

D. A dressing that forms a gel that interacts with the wound surface
A hydrocolloid dressing is made of materials that are adhesive and can form a gel over the open area of the wound. Since moisture enhances wound healing, the gel that forms places the wound in the proper environment for healing.

65
Q
  1. Which of the following is an indication for a binder to be placed around a surgical patient with a new abdominal wound?
    A. Collection of wound drainage
    B. Reduction of abdominal swelling
    C. Reduction of stress on the abdominal incision
    D. Stimulation of peristalsis (return of bowel function) from direct pressure
A

C. Reduction of stress on the abdominal incision
A binder placed over the abdomen can provide protection to the abdominal incision by offering support and decreasing stress from coughing and movement.

66
Q

When is an application of a warm compress indicated? (Select all that apply.)
A. To relieve edema
B. For a patient who is shivering
C. To improve blood flow to an injured part
D. To protect bony prominences from pressure ulcers
Rationale

A

When is an application of a warm compress indicated? (Select all that apply.)

A. To relieve edema
C. To improve blood flow to an injured part
Warm compresses can improve circulation by dilating blood vessels, and they reduce edema. The moisture of the compress conducts heat.

67
Q 
On assessing your patient's sacral pressure ulcer, you note that the tissue over the sacrum is dark, hard, and adherent to the wound edge. What is the correct stage for this patient's pressure ulcer?
A.	Stage II
B.	Stage IV
C.	Unstageable
D.	Suspected deep tissue damage
Rationale
A

C. Unstageable
To determine the stage of a pressure ulcer you examine the depth of the tissue involvement. Since the pressure ulcer assessed was covered with necrotic tissue, the depth could not be determined. Thus this pressure ulcer cannot be staged.
