EXAM COVERAGE
1. Wound Physiology, Pathophysiology, and Tissue Healing Dynamics
2. Comprehensive Wound Assessment, Diagnostic Evaluation, and Etiology Differentiation
3. Advanced Wound Bed Preparation, Debridement Modalities, and Moisture Balance
4. Pressure Injury Prevention, Staging Systems, and Advanced Support Surfaces
5. Specialized Wound Etiologies: Vascular, Neuropathic, Fistulas, and Complex Dermatological
Conditions
1. A 68-year-old male with long-standing type 2 diabetes mellitus presents with a chronic, non-
healing neuropathic ulcer over the plantar aspect of the first metatarsal head. The wound bed
exhibits pale granulation tissue with undermined borders and a surrounding rim of firm,
hyperkeratotic callus. Despite offloading with a total contact cast for six weeks, the wound has
decreased in depth by only 10%. Which underlying pathophysiological process is the most
critical primary contributor to the arrested healing in this patient?
A. Chronic venous hypertension leading to leukocyte trapping and fibrin cuff formation
B. Platelet-derived growth factor deficiency and localized cellular senescence due to
advanced glycation end-products
C. Uncontrolled bacterial biofilm proliferation mediated by Pseudomonas aeruginosa exotoxins
D. Severe macrovascular arterial insufficiency caused by calcific medial arterial sclerosis
Answer: B [Correct Answer]
Rationale: Chronic diabetic foot ulcers frequently exhibit impaired cellular proliferation,
reduced growth factor expression, and cellular senescence driven by advanced glycation end-
products (AGEs) accumulation and hypoxia. Option A describes venous leg ulcers. Option C
contributes to bioburden but is not the primary intrinsic cellular defect in diabetic wounds.
, Option D refers to peripheral artery disease, which must be differentiated from purely
neuropathic etiology.
2. A 74-year-old female is admitted to a skilled nursing facility with a deep partial-thickness
pressure injury on her right heel measuring 3.5 cm x 2.0 cm. The wound base is covered by
firmly adherent, dry, leathery black eschar with no surrounding erythema or fluctuance. Pedal
pulses are palpable, and ankle-brachial index (ABI) is 1.10. According to current national
pressure injury advisory panels, what is the most appropriate initial management for this stable
heel eschar?
A. Immediate surgical excision in the operating room to rule out underlying osteomyelitis
B. Leave intact and dry as a natural biological cover, provided there is no clinical sign of
infection or fluctuance
C. Apply autolytic debridement hydrogel dressings daily under a rigid compression wrap
D. Perform sharp bedside debridement of the entire eschar down to healthy periosteum
Answer: B [Correct Answer]
Rationale: Stable, dry, intact eschar on ischemic or pressure-compromised heels without
erythema, drainage, or fluctuance acts as a biological barrier and should not be debrided.
Option A and D risk introducing infection and creating deep open wounds on low-perfusion
anatomical sites. Option C introduces moisture that can convert dry necrosis to wet gangrene if
unrecognized ischemia or bacterial proliferation is present.
3. A wound care nurse is evaluating a 55-year-old female presenting with a painful, irregular ulcer
on the medial distal third of her lower extremity. Physical examination reveals 2+ pitting edema,
lipodermatosclerosis, atrophie blanche, and brownish hyperpigmentation from hemosiderin
deposition. Palpable dorsalis pedis and posterior tibial pulses are strong. What is the foundational
cornerstone of local and systemic management for this pathology?
A. Strict continuous absolute bed rest with limb elevation above the heart level
B. Graduated compression therapy delivering adequate sub-bandage pressure, provided
arterial disease is excluded
C. Immediate application of silver-impregnated antimicrobial dressings to eradicate colonization
D. Surgical revascularization via saphenous vein bypass graft
Answer: B [Correct Answer]
Rationale: Venous leg ulcers are managed primarily by reversing ambulatory venous
hypertension through graduated compression therapy after confirming an adequate arterial
, blood supply. Option A is impractical and unnecessary for long-term healing. Option C
addresses bioburden but fails to correct the underlying hemodynamic etiology. Option D is
indicated for arterial insufficiency, not isolated venous disease.
4. An 82-year-old male resident in a long-term care facility develops a stage 3 pressure injury over
the sacrum measuring 4.0 cm x 3.0 cm with 50% pink granulation tissue and 50% yellow slough.
The periwound skin is macerated due to frequent urinary incontinence. Which combination of
local wound care products is most appropriate to manage the wound bed and protect the
periwound?
A. Dry gauze packing with zinc oxide barrier paste applied to the wound bed
B. Hydrogel for autolytic debridement combined with a polyurethane foam dressing and a
moisture barrier film for the periwound
C. Occlusive hydrocolloid dressing changed every 24 hours regardless of fluid strikethrough
D. Povidone-iodine soaked gauze packing changed twice daily to ensure rapid desiccation of
slough
Answer: B [Correct Answer]
Rationale: Hydrogel provides moisture to facilitate autolytic debridement of slough, foam
absorbs excess exudate to prevent periwound maceration, and skin sealants/barriers protect
vulnerable skin from incontinence. Option A uses dry gauze which desiccates viable tissue.
Option C under-manages moderate exudate. Option D uses cytotoxic iodine which delays
granulation tissue formation.
5. A 60-year-old male with end-stage renal disease and calciphylaxis presents with extremely
painful, violaceous, reticulated skin lesions on his abdomen and thighs that have progressed to
necrotic ulcerations with black eschar. Laboratory values show elevated serum calcium-
phosphate product. What is the primary interprofessional management strategy required for this
complex condition?
A. Immediate surgical debridement of all necrotic tissue to promote rapid secondary intention
healing
B. Multifactorial approach including sodium thiosulfate therapy, non-protein-bound pain
management, and calcium-phosphate homeostasis optimization
C. High-dose systemic corticosteroid therapy to suppress local immune-mediated microvascular
thrombosis
D. High-pressure hyperbaric oxygen therapy as primary monotherapy without metabolic
intervention
, Answer: B [Correct Answer]
Rationale: Calciphylaxis (calcific uremic arteriolopathy) requires a multidisciplinary approach
focusing on metabolic correction, sodium thiosulfate to chelate calcium, and specialized pain
management. Option A can exacerbate ulcer progression and worsen intractable pain in
calciphylaxis. Option C is contraindicated as it can worsen bone and mineral metabolism.
Option D has limited efficacy without correcting systemic calcium-phosphate imbalance.
6. A wound care nurse is assessing a chronic surgical dehiscence wound in the abdominal wall. The
wound measures 8 cm in length, 4 cm in width, and 6 cm in depth with extensive undermining
from 2 o'clock to 6 o'clock. Moderate to heavy serosanguinous drainage is noted. Which
intervention is indicated to manage deep undermining and promote granulation?
A. Packing tightly with wet-to-dry coarse cotton gauze until bleeding is induced
B. Loosely filling undermined spaces with moistened ribbon gauze or applying negative
pressure wound therapy (NPWT)
C. Applying a dry transparent film dressing directly into the deep wound cavity
D. Suture closure of the undermined pockets at the bedside using local anesthesia
Answer: B [Correct Answer]
Rationale: Undermined spaces must be loosely filled to avoid pressure necrosis or premature
bridging while ensuring contact with the wound base; NPWT is also highly effective for complex
dehisced wounds. Option A causes pain, bleeding, and cellular trauma. Option C creates a dead
space prone to seroma and abscess formation. Option D cannot be performed safely at the
bedside in infected or contaminated undermined margins.
7. A 65-year-old female presents with a chronic ulcer on the lateral malleolus of her left ankle. The
wound bed is pale, dry, and necrotic with exposed tendons. She reports severe nocturnal resting
pain that is temporarily relieved by hanging her foot over the edge of the bed. Palpable pulses are
absent, and ABI is 0.45. What is the most imperative initial action for this patient?
A. Apply multilayer high-compression bandaging immediately to control swelling
B. Urgent vascular surgery consultation for diagnostic angiography and revascularization
assessment
C. Initiate aggressive sharp debridement of the lateral malleolus at the bedside
D. Apply enzymatic collagenase ointment under a non-adherent contact layer
Answer: B [Correct Answer]
