A patient has a wound with 100% yellow slough covering the wound bed. Which debridement method is most appropriate when the patient has poor circulation and cannot tolerate sharp debridement?
Answer: Enzymatic debridement
Enzymatic debridement uses topical agents (e.g., collagenase) to selectively dissolve necrotic tissue and is appropriate when sharp debridement is contraindicated.
Which layer of the skin contains the Meissner's corpuscles and is responsible for most immune defense?
Answer: Dermis
The dermis houses mechanoreceptors such as Meissner's corpuscles, as well as immune cells, blood vessels, and collagen fibers.
A PT is treating a patient with a venous insufficiency ulcer. Which characteristic finding is most consistent with this diagnosis?
Answer: Shallow ulcer with irregular edges around the medial malleolus
Venous insufficiency ulcers classically appear as shallow, irregular wounds around the medial malleolus with surrounding hemosiderin staining and edema.
A patient presents with a stage 2 pressure injury. What is the correct description of this injury?
Answer: Partial-thickness skin loss with a shallow open wound
A stage 2 pressure injury involves partial-thickness loss of the dermis, presenting as a shallow open ulcer or an intact or ruptured seroma-filled blister.
Which dressing type provides a moist wound environment, is self-adhesive, and is most appropriate for a clean stage 2 pressure injury with minimal exudate?
Answer: Hydrocolloid dressing
Hydrocolloid dressings maintain a moist environment, are self-adhesive, and are ideal for low-exudate wounds such as stage 2 pressure injuries.
A patient with diabetes has neuropathy and presents with a plantar forefoot ulcer. The wound is surrounded by callus and has no signs of infection. What is the first priority in management?
Answer: Debridement of the surrounding callus and offloading
Offloading pressure and debriding the callus (which concentrates stress) are the primary interventions for neuropathic diabetic foot ulcers.
When assessing a wound using the RYB (Red-Yellow-Black) classification, which color indicates the presence of infection or fibrinous slough requiring cleaning?
Answer: Yellow
In the RYB system, yellow indicates the presence of fibrinous slough, purulent exudate, or infection that must be cleaned before healing can progress.
