Lower extremity arterial disease (___) is a progressive narrowing or blockage of arteries in the lower limbs, often due to atherosclerosis (McNichol et al., 2021). It is commonly associated with PAD and defined by an ABI < 0.9, leading to ischemia in the lower leg.

____ leg ulcers are often triggered by trauma, such as blunt force or chronic pressure from improperly fitting footwear.
Arterial
PAD
Critical Limb Ischemia
Is the most severe form of LEAD, where blood flow is so poor that tissues cannot survive (DynaMed, 2022). Most individuals with CLI also have diabetes. Without appropriate revascularization, these patients often face amputation, with the risk increasing as their ABI decreases.
Risk Factor for Arterial Disease Modifialble:

ALU characteristics
* well-defined, round, or "punched-out" appearance with sharply demarcated edges.
Wound bed pale, gray, or yellowish due to the lack of oxygen-rich blood reaching the area. The wound bed may also be dry and necrotic, with necrotic tissue ranging from thick black eschar to slough.
* Minimal exudate because of lack of blood supply
* Periwound Periwound -This is often thin, shiny, dry, and cool to the touch.
What does ABI stand for and mean?
An ankle-brachial index (ABI) is a painless test that measures blood pressure in your ankles and arms. It shows if you have peripheral artery disease (PAD), or plaque buildup in your leg arteries. Your ABI is the blood pressure in your ankle divided by that in your arm. * Can catch PAD before it gets severe!
When is an ABI test needed?
- if you have PAD symptoms, like leg pain when active. Your PCP may also suggest this test if you don’t have symptoms but are:
- Age 65 or older
- Age 50 to 64 and have certain risk factors for atherosclerosis (like diabetes, high blood pressure, high cholesterol, history of tobacco use) or a history of PAD in your biological family
- Under age 50 and have diabetes along with another risk factor for atherosclerosis
Below are preparations for what kind of test/procedure?
- Don’t eat or drink anything that contains caffeine on the day of your test.
- Don’t use tobacco products or alcohol during the hour before your test.
- Don’t exercise during the hour before your test.
- Wear loose, comfortable clothes so your provider can easily access your upper arms and ankles.
- Just before the test, go to the restroom and pee until your bladder is empty.
Be sure to tell your provider if you’ve had any procedures to improve circulation in your legs. This may affect how they do the test.

There is partial-thickness skin loss, and the surrounding skin is intact. How should this pressure injury be staged?
Stage 2
* Stage 2 is defined as partial-thickness skin loss with exposed dermis. It typically presents as a shallow, open ulcer or a ruptured blister. The wound bed is viable, moist, and red-pink in color, without slough, eschar, or exposure of deeper tissues like muscle or bone

Osteomyelitis
60.
When treating diabetic foot ulcer infections, what primarily guides the duration of antibiotic therapy?
Response to therapy
61.
A patient with a venous insufficiency wound has been receiving weekly debridement, silver alginate dressings, and multilayer compression. Despite adherence, the wound shows no significant improvement after six weeks. What should the clinician do next?
Obtain a tissue biopsy to rule out an unsuspected diagnosis such as vasculitis or malignancy.

62.
Which topical treatment is MOST appropriate for managing localized wound pain?
Lidocaine gel or creams
63.
Which phase of wound healing is hindered by the presence of necrotic tissue?

70.
You are re-evaluating the wound of a patient with diabetes who has no measurable healing over the past three weeks. You suspect osteomyelitis as the underlying cause. Which labs would be most appropriate to confirm your suspicion?
Complete blood count (CBC), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP)

43
Which agent in antimicrobial dressings attaches to the bacterial cell membrane causing structural changes that kill the bacteria?
Polyhexamethylene biguanide (PHMB)
* There are a few key agents in modern antimicrobial dressings that function by attaching to and disrupting the bacterial cell membrane, causing fatal structural changes. The two most prominent are Antimicrobial Peptides (AMPs) and Polyhexamethylene Biguanide (PHMB)

Teach him how to apply lymphedema wraps daily to promote lymphatic drainage and filtration.
Q36
What therapy is recommended for extensive open wounds, especially after surgical debridement and/or infection?
Negative pressure wound therapy
Q35
If clinical suspicion for osteomyelitis is high and radiographs are not confirmative, what IMAGING study is indicated NEXT?
