WOUND CERTIFICATION FINAL EXAM Questions and Correct Answers

Document Content and Description Below

what are 6 risk factor components of Braden Scale for pressure ulcer? - Answersensory perception, moisture, mobility, activity, nutrition, and shear/friction What is the name of the organization tha... t developed the pressure ulcer staging? - Answer-NPUAP (national pressure ulcer advisory panel) pathological effect of excessive pressure on soft tissue can be attributed by 3 factors? what are they? - Answer-tissue tolerance, duration of pressure, and intensity of pressure what are the extrinsic factors that impact pressure ulcers? - Answer-increase in moisture, friction and shearing how does friction play a role in shearing which eventually leads to pressure ulcer? - Answer-friction alone causes only superfical abrasion, but with gravity it plays a synergistic effect leading to shearing. When gravity pushes down on the body and resistance (friction) between the patient 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? - Answer-nutritional debilitation, advanced age, low BP, stress, smoking, elevated body temperature Aging skin undergoes what elements affecting risk for pressure ulcer? - Answerdermoepidermal junction flattens, less nutrient exchange occurs, less resistance to shearing, changes in sensory perception, loss of dermal thickness, increased vascular fragility; ability of soft tisuse to distribute mechanical load w/out comprosing blood flow is impaired [Show More]
