2 Disease Prevention Asepsis: absence of disease-producing microorganismsAsepsis: absence of disease-producing microorganisms Medical Asepsis: medical practice that reduces the numbers of microorganisms or interrupts transmission from one person to another person or from person to place or object.Medical Asepsis: medical practice that reduces the numbers of microorganisms or interrupts transmission from one person to another person or from person to place or object. HandwashingHandwashing Using nonsterile gloves when in contact with blood, moist body fluid (except sweat), secretions, excretions, mucous membranes or non-intact skinUsing nonsterile gloves when in contact with blood, moist body fluid (except sweat), secretions, excretions, mucous membranes or non-intact skin Cleaning and/or disinfecting equipmentCleaning and/or disinfecting equipment

7 Disease Prevention Handwashing: most important measure the nursing assistant can take to prevent the spread of diseaseHandwashing: most important measure the nursing assistant can take to prevent the spread of disease Should always occur before and after:Should always occur before and after: Direct patient careDirect patient care Handling foodHandling food Touching a woundTouching a wound Using the bathroomUsing the bathroom Should last a minimum of 30 seconds, or longer if visibly soiledShould last a minimum of 30 seconds, or longer if visibly soiled Use soap from dispenser instead of bar soapUse soap from dispenser instead of bar soap Alcohol-based cleaners can be used for routine handwashing, unless hands are visibly soiledAlcohol-based cleaners can be used for routine handwashing, unless hands are visibly soiled
