Question | Answer |
---|---|
Define Cleaning? | The first space in processing all equipment. Equipment is washed to remove dirt and organic material. |
Define Disinfection? | Destroys the vegetative forms of pathogens, BUT NOT SPORES |
Define Low-Level? | Will NOT KILL resistant microorganisms |
Define Intermediate-Level? | Kills all vegetative bacteria and fungi, BUT NOT CERTAIN VIRUSES |
Define High-Level? | Kills all vegetative microorganisms |
Define Sterilization? | The complete destruction of all microorganisms |
What is Pasteurization? | An intermediate-level disinfection process that involves immersing equipment in a hot water bath 70 degree C for 30min |
List the low-level disinfectants | Acetic Acid (1 part vinegar 3 parts distilled water) & Quaternay Ammonium Compounds (Used on ventilators) |
List the intermediate-level disinfectants | Ethyl & Isopropyl Alcohol/Phenolics/Iodophors (all surface area and skin) |
List the high-level disinfectants | Glutaraldyde- kills spores w. 3hr exposure time. Used on tubing/ bronchoscopes/airways/resuscitation bags |
High-Level Chemical disinfectants | Hydrogen Peroxide/Sodium Hypochlorite (Bleach)/Peracetic Acid |
What is Autoclaving? | Use of steam under pressure of 15psi @ 121 degrees C (most common) |
What are the Thermos indicators of Autoclaving? | Temperature and Exposure |
What are the Biological indicators of Autoclaving? | Sterilization |
What is Ionizing Radiation? | Cleaning using X-Rays and Gamma Rays but the cost are high with long exposure time of 48-72hrs |
What is Ethylene Oxide Sterilization? | Good for heat sensitive equipment. ETO @450mg/L. Relative Humidity @30-60%. Temperature @50-60 degrees C |
What are the 3 risk Categories? | 1. Critical- devices directed into the bloodstream of body 2. Semicritical- devices that directly or indirectly contact mucous membrane 3. Noncritical- devices that do not contact the patient or only contact healthy skin |
T/F Critical requires sterilization? | True |
T/F Semicritical requires High-Level disinfection? | True |
T/F Noncritical requires low to intermediate-level disinfection? | True |
