Nursing Best Practice GuidelineIntegrated Bed System: A bed frame and support surface that are combined into a single unitwhereby the surface is unable to function separately.Non-Powered: Any support surface not requiring or using external sources of energy for operation(Energy = D/C or A/C).Powered: Any support surface requiring or using external sources of energy to operate (Energy = D/Cor A/C).Overlay: An additional support surface designed to be placed directly on top of an existing surface.Mattress Replacement: A support surface designed to be placed directly on the existing bed frame.Surfactants: A surface-active agent that reduces the surface tension of fluids to allow greaterpenetration (AHCPR, 1994).Tissue Biopsy: Use of a sharp instrument to obtain a sample of skin, muscle, or bone (AHCPR, 1994).Needle Aspiration Biopsy: The removal of tissue using a needle.Punch Biopsy: The removal of a small piece of tissue with a hollow round cutting tool.Tissue Load: The distribution of pressure, friction and shear on tissue (AHCPR, 1994).Topical Antibiotic: A drug known to inhibit or kill microorganisms that can be applied locally toa tissue surface (AHCPR, 1994).Topical Antiseptic: Product with antimicrobial activity designed for use on skin or othersuperficial tissues; may damage some cells (AHCPR, 1994).Trochanter: Bony prominence on the upper part of the femur.Tunneling: A passageway under the surface of the skin that is generally open at the skin level;however, most of the tunneling is not visible (AHCPR, 1994).Underlying Tissue: Tissue that lies beneath the surface of the skin such as fatty tissue,supporting structures, muscle, and bone (AHCPR, 1994).Undermining: A closed passageway under the surface of the skin that is open only at the skinsurface. Generally it appears as an area of skin ulceration at the margins of the ulcer with skinoverlaying the area. Undermining often develops from shearing forces (AHCPR, 1994).79
