Download WOUND CERTIFICATION EXAM 2024/2025 (ACTUAL QUESTIONS AND ANSWERS) and more Exams Pathology in PDF only on Docsity! What are 6 risk factor components of braden scale for pressure ulcer? Sensory percep9on, moisture, mobility, ac9vity, nutri9on, and shear/fric9on What is the name of the organiza9on that developed the pressure ulcer staging? Npuap (na9onal pressure ulcer advisory panel) Pathological effect of excessive pressure on soE 9ssue can be aFributed by 3 factors? What are they? Tissue tolerance, dura9on of pressure, and intensity of pressure What are the extrinsic factors that impact pressure ulcers? Increase in moisture, fric9on and shearing How does fric9on play a role in shearing which eventually leads to pressure ulcer? Fric9on alone causes only superfical abrasion, but with gravity it plays a synergis9c effect leading to shearing. When gravity pushes down on the body and resistance (fric9on) between the pa9ent and surface is exerted, shearing occurs. Because skin does not freely move, primary effect of shearing occurs at the deeper fascial level. What are the intrisinc factors of pressur ulcers? Nutri9onal debilita9on, advanced age, low bp, stress, smoking, elevated body temperature Aging skin undergoes what elements affec9ng risk for pressure ulcer?

Begins w/buring pain, followed by erythema that evolves into a grouped unilateral vesicular rash along one or two dermatomes. Pustules form, rupture, and then becomes crusty. Of note, dermatomes are specific skin surface areas innervated by a single spinal nerve group What kind of lesion is an important diagnos9c feature in candidiasis? Satellite lesion What are the 2 mechanims for wound healing? Regenera9on (replacement of damaged or lost 9ssue with more of the same) or scar forma9on (replacement of damaged or lost 9ssue by connec9ve 9ssue that lacks some fx of original 9ssue Wounds that are confined to epidermal and superficial dermal layers heal by what mechanism and why? Regenera9on; epithelial, endothelial, and connec9ve 9ssue can be reproduced Wounds that occur deep in the dermal structures, sq 9ssue, muscle, tendon, ligaments, and bone heal by what mechanism and why? Scar forma9on; these layers lack capacity to regenerate and therefore loss of these structures are permanent Explain wound healing by primary inten9on and give an example? In primary inten9on, wound edges are well approximated and heals by epithealiza9on and connec9ve 9ssue deposi9on. Surgical incision secured w/staples, surtures, or adhesive tape Explain wound healing by secondary inten9on and give and example? Wound edges are not approximated and healing occurs by granula9on 9ssue forma9on, contrac9on of wound edges, and epithelializa9on. Chronic wounds such as pu and dehisced incisions Explain wound healing by ter9ary inten9ons and give examples? Aka delayed primary inten9on. Wound is kept open for several days. Superficial wound eges then are approximated, and center of wound heals by granula9on 9ssue forma9on. Abdominla incision complicated by significant infec9on (deep 9ssue is healing by graula9on and superficial layer of skin is sutured) "red islets" represent what part of the skin layer? Basement membrance of the epidermis, which projects deep into the dermis to line the epidermal appendages. Each islets serves as a source of new epithelium Why is migra9on in wound healing delayed when wound is covered w/ a scab? In order to create a moist envinroment, epithelial cells secrete enzymes knwon as mmp (metallproteinases) to liE the scab What are the major components of par9al-thickness repair include? 1. Inflammatory response to injury 2. Epithelial prolifera9on and migra9on (resurfacing) 3. Differen9a9on of the epidermal layers to restore barrier fx of skin What happens in wound healing, if wound involves dermal loss Granula9on forma9on or connec9ve 9ssue repair will precede concurrently with reepithealiza9on When do you know complete healing has occured in epithelial resurfacing or healing by regenera9on? When skin pigmena9on matches the individual's normal skin tone What must be restored in par9al dermal loss in wound healing? Rete ridges/dermal papillae What are the key components of prolifera9ve phase? Epithealiza9on, neoangiogenesis, and matrix deposi9on/collagen synthesis What are the 4 major phases in full-thickness repair? 1. Hemostasis (platelets degranulate and release growth factors) 2. Inflammatory (leakage of neutrophils, macrophages ) 3. Prolifera9ve/rebuilding (cont recruitment of growth factors, granula9on forma9on, contrac9on of wound edges, epithelial resurfacing) 4. Matura9on/remodeling (collagen synthesis) Granula9on 9ssue is oEen referred to as Extracellular matrix (ecm) In full-thickness wounds, why is the new epidermis slightly thinner than original epidermis? Ret pegs that normall dip into dermis is lacking In chronic wounds where wound is healing by secondary inten9on, why is healing delayed?
