wound certification exam questions with correct answers

what are 6 risk factor components of Braden Scale for pressure ulcer? Answer sensory perception, moisture, mobility, activity, nutrition, and shear/friction What is the name of the organization that 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
