gaiter area of the leg (calf from below knee to above ankle)

24
Q

What are common signs of venous ulcers?

Study These Flashcards
A
  • Edema often present
  • Hemosiderin staining

  • Weeping and itching of skin often present
25
What is a huge part of treatment for venous stasis ulcers to control edema?
Compression therapy- compression stockings
26
You should AVOID compression stockings when __________ flow is compromised
arterial
27
How much compression pressure should you wrap a venous ulcer in?
40-60 mmHg
28
You have a wet wound... what type of dressing should you use?
Alginate and foam
29
This type of ulcer is due to decrease in arterial blood supply to lower extremity
Arterial ulcer
30

PVD, diabetes, sickle cell
31
Arterial ulcers result in tissue ________ and damage/ulcer formation
hypoxemia
32
Arterial ulcers have a ___________ capillary refill time
Reduced
33
Arterial ulcer may also have reduced __________ _____
palpable pulses
34
What are some characteristics of an arterial ulcer?
- Painful - Ulcer appears punched out with well demarcated edges - Pale, often necrotic base - Surrounding skin dusky or shiny, hairless
35
You should not decide if an ulcer is venous or arterial based on what?
the appearance of hair whether hairless or not
36
Is a venous or arterial ulcer more painful?
Arterial
37
Are medications used to treat arterial ulcers?

Venous
41
Mainstay treatment for venous ulcer?
Compresison
42
This test is helpful in determining extent of peripheral vascular disease?
ABI

At rest and supine for 10 min
45
What is the acceptable range for an ABI?
0.9-1.4
46
An ABI greater than _____ means a noncompressable calcification of vessels
1.4
47

What ABI is indicative of severe arterial disease?
Less than 0.5
49
What ABI value is considered diagnostic of PAD?
below 0.9
50
How does a negative pressure wound therapy- wound vac enhance wound healing?
- Reducing edema - Increasing rate of granulation tissue formation - stimulation of circulation
51
What are contraindications for a wound vac placement? Meaning when would you NOT use a wound vac?
- Malignancy of wound - Untreated osteomyelitis - Placement of dressings in contact with exposed blood vessels, organs or nerves - Nonenteric or unexplored fistulas
