Getting Ready for Certification

The United States’ Centers for Medicare and Medicaid Services (CMS) estimate that approximately 10.5 million people are afflicted with chronic wounds, representing around 2.5% of the total population of the United States.1 The public health burden of chronic wound management is further complicated by a lack of access to skilled wound care specialists, contributing to health care disparities and less than optimal healing outcomes.1,2 Considering this public health concern, there is a need for skilled wound care specialists such as the Wound Treatment Associate—Certified (WTA-C®), Certified Wound Care Nurse (CWCN®), and Advanced-Practice Certified Wound Care Nurse (CWCN-AP®) or the Certified Wound, Ostomy and Continence Nurse (CWOCN). One of the main competencies of certified wound care specialists is determining wound etiology by performing a focused assessment to guide treatment. During the initial patient encounter, the CWCN® or CWCN-AP® creates a holistic wound healing roadmap by performing a focused assessment of the patient. Identifying etiologic factor leading to wound development is essential for diagnosis and formation of a treatment plan.3,4 Factors include pressure and shearing forces, lower extremity venous disease (LEVD), lower extremity arterial disease (LEAD), neuropathy, trauma, surgical, or thermal burns are common causes of chronic wounds encountered by the CWCN® or CWCN-AP®. The certified nurse relies on a number of characteristics when identifying wound etiology such as location, clinical manifestations, history and others. Pressure injuries are caused by skin and soft tissue damage resulting from pressure or in combination with shear and are typically located over bony prominences and follow staging based on the depth of anatomical tissue destruction. Incontinence-associated dermatitis (IAD) is caused by fecal or urinary incontinence. Lower Extremity Arterial Disease (LEAD) and Lower Extremity Venous Disease (LEVD) are caused by vascular insufficiency; these lesions are commonly located on the lateral malleolus and mid-tibial area (LEAD) versus the medial malleolus (LEVD). Neuropathic ulcers are usually associated with diabetic-related neuropathy, although not all of these ulcers are caused by diabetes mellitus. They are usually located on the plantar aspect of the foot.3,4 A focused assessment also provides a blueprint for management. Chronic wounds may become stalled in the inflammatory phase of wound healing, resulting in periwound skin damage; additional manifestations include induration, fluctuance, denudation and maceration.3-5 The periwound skin provides clues to the health of the wound base. The base may contain viable tissues, nonviable tissues or a mixture of both. A viable wound bed usually contains beefy, red granulation tissue, indicating it is in the proliferative phase or found healing. In contrast, the presence of nonviable tissues may such as slough or eschar must be eliminated through debridement (autolytic, enzymatic, or sharp/surgical). The WTA-C®, CWCN®, or CWCN-AP® must be able to recognize potential signs of stalled wound healing, such as signs of infection, epibole, and presence of biofilm that prolong the inflammatory phase and impede wound healing.3-5 The wound care specialist may also use evidence-based risk assessment instruments such as the Braden scale, Braden Q scale, and Norton Plus Scale.3 Successful management of a chronic wound is based on this careful assessment with the ultimate goal of achieving wound healing.2,4,5 WTA-C® QUESTION 1. You are assessing a patient with an abdominal wound with moderate serosanguineous drainage. The wound base has 100% beefy-red granulation tissue with no slough or eschar. Which dressing choice is the most appropriate for managing this wound? A. Hydrocolloid dressing. B. Alginate dressing. C. Transparent film dressing. D. Hydrogel dressing. Exam Content Outline: 1.2 CORRECT ANSWER: B. ALGINATE DRESSING Rationale: Alginate dressings are highly absorbent and appropriate for wounds with moderate to heavy exudate. They also help manage slough by promoting autolytic debridement. Hydrocolloid and transparent film dressings are better suited for low-exudate wounds, and hydrogel is used for dry wounds 1, 2 REFERENCES Bates-Jensen BM. Assessment of the patient with a wound.

The WTA-C® is assessing a patient with a stage 4 pressure injury on the sacrum. To develop an effective care plan, what data should be collected during the wound assessment? A. Patient’s pain level and emotional distress related to the wound B. Color, drainage, wound size, depth, and presence of undermining or tunneling C. The patient’s dietary preference and fluid intake D. The patient’s perceptions of wound healing progress and past wound experience Exam Content Outline: 1.2 CORRECT ANSWER: B. COLOR, DRAINAGE, WOUND SIZE, DEPTH, AND PRESENCE OF UNDERMINING OR TUNNELING Rationale: Objective wound-related assessment relies on observable and measurable characteristics. Such characteristics include wound size, depth, drainage, color, presence of infection, undermining or tunneling that guide subsequent management.1 While answer choices A, C and D are important, they are subjective and supportive factors rather than direct objective wound measurement.2 REFERENCES Bates-Jensen BM.

He has a past medical history of neuropathy and poor wound healing. Which intervention is most appropriate to promote wound healing? A. Offloading with a total contact cast (TCC). B. Applying a transparent film dressing. C. Initiating systemic antibiotics prophylactically. D. Using an inelastic compression bandage. Exam Content Outline: 010201, 010207 CORRECT ANSWER: A. OFFLOADING WITH A TOTAL CONTACT CAST (TCC) Rationale: A total contact cast (TCC) is the gold standard for offloading pressure from diabetic foot ulcers, particularly in patients with neuropathy. The TCC redistributes weight and reduces mechanical stress on the ulcer. Transparent film dressings and compression bandages are not appropriate for this condition. Systemic antibiotics are used only if there are definitive signs of infection.1 REFERENCE Nix, D. Skin and wound inspection and assessment. In Bryant, R., Nix, D. Eds. Acute and Chronic Wounds Intraprofessionals from Novice to Expert. 6th ed. St. Louis, MO: Elsevier, 2024:199. 4. A patient with diabetes mellitus presents with a non-healing plantar foot ulcer and no palpable pulses. Upon assessment, you also notice thick toenails. What diagnostic test should be performed first? A. Duplex ultrasound. B. Ankle-brachial index (ABI). C. Magnetic resonance imaging (MRI). D. CT angiography. Exam Content Outline: 010207, 010210 CORRECT ANSWER: B. ANKLE-BRACHIAL INDEX (ABI) Rationale: An ABI is the first-line diagnostic tool for assessing peripheral arterial disease (PAD) in patients with non-healing foot ulcers.1 It provides clinicians with a quick assessment of blood flow. If further vascular imaging is needed, duplex ultrasound, MRI, and CT angiography may be used later.2 REFERENCES Nix, D. Skin and wound inspection and assessment. In Bryant, R., Nix, D. Eds.

A patient with chronic venous insufficiency has developed venous ulcers to her bilateral lower extremities, around the gaiter-area. Her legs are swollen and slightly erythematous, with scattered hemosiderin staining. What is the most appropriate intervention for this condition? A. Apply an inelastic compression bandage. B. Recommend a hyperbaric oxygen treatment. C. Perform surgical debridement immediately. D. Prescribe systemic antibiotics. Exam Content Outline: 010207 CORRECT ANSWER: A. APPLY AN INELASTIC COMPRESSION BANDAGE Rationale: Inelastic compression is the first-line therapy for ambulatory patients with venous ulcers, as it provides adequate pressure to enhance venous return and support healing. 1Hyperbaric oxygen treatment is not typically indicated for venous ulcers. Surgical debridement is reserved for specific cases involving infection or necrosis. Antibiotics are used only when there is clear evidence of infection.1BOX - SUPPLEMENTAL DIGITAL CONTENT: This document from Linda McKenna, MSN, RN, CWOCN (see Supplemental Digital Content document, http://links.lww.com/JWOCN/A143), provides a comprehensive guide for certified WOC nurses to pursue recertification using Professional Growth Points (PGP).
