Document Summary
A sterile field: is an area free of microorganism and prepared to receive sterile items. Understanding skin integrity helps you maintain skin integrity and promote wound healing. When the skin is injured, the epidermis functions to resurface the wound and restore the barrier against invading organism while the dermis responds to restore the structural integrity and the physical properties of the skin. Reduced skin elasticity, decreased collage, and thinning of underlying muscle and tissues, and cause the older adults skin to be easily torn via mechanical trauma and especially shearing force. Concomitant medical condition and polypharmacy interfere with wound healing. The attachment between the epidermis and dermis becomes flattened in older adults, allowing the skin to be easily torn from mechanical trauma (e. g. tape removal) Diminish inflammatory response, resulting in slow epithelialization and wound healing. The hypodermis decrease in size with age. Older pt. have little subcutaneous padding over bony prominences, so they are more prone to skin breakdown.
