CBSPD Sterilization - Certification Exam Review WITH CORRECT SOLUTIONS

Steam Using Gravity Displacement: Method of Killing Denatures microorganism proteins Steam Using Gravity Displacement: Sterilant Used Combination of steam and ambient air Steam Using Gravity Displacement: How do steam and ambient are sterilize? Steam displaces the air, and forces it out of the drain vent. Steam then comes in direct contact with items Steam Using Gravity Displacement: Parameters (3) 1. Time 2. Temperature 3. Pressure Steam Using Gravity Displacement: Common cycle times (3) 1. 30 min, 250°F, 15 psi 2. 15-25 min, 275°F, 27 psi 3. 10 min, 275°F, 30 psi Steam Using Gravity Displacement: Items that CAN be sterilized 1. Critical items that are heat and moisture resistant 2. Semi-critical items that are heat and moisture resistant 3. Sharps Containers Steam Using Gravity Displacement: Items that CANNOT be sterilized Heat and moisture sensitive materials Steam Using Gravity Displacement: Biological Indicator Geobacillus Stearothermophilus Steam Using Dynamic Air Removal: Method of Killing Denatures microorganism proteins Steam Using Dynamic Air Removal: Sterilants Used (3) 1. Combination of steam and ambient air 2. Prevacuum Sterilizers 3. (SFPP) Steam-flush pressure-pulse sterilizers Steam Using Dynamic Air Removal: Parameters (3) 1. Time 2. Temperature 3. Pressure Steam Using Dynamic Air Removal: Common Cycle Times (2) 1. 4 min, 270°F, 28-30 psi 2. 3 min, 275°F, 28-30 psi Steam Using Dynamic Air Removal: Items that CAN be sterilized 1. Critical items that are heat and moisture resistant 2. Semi-critical items that are heat and moisture resistant 3. Sharps Containers Steam Using Dynamic Air Removal: Items that CANNOT be sterilized Heat and moisture sensitive items Steam Using Dynamic Air Removal: Biological Indicator Geobacillus Stearothermophilus EO: Method of Killing Alkylation: interferes with microorganism metabolism EO: Sterilants Used (2) 1. 100% EO (undiluted) - common 2. EO Mixtures (contains HCFC and CO2) - uncommon EO: Parameters (5) 1. Time 2. Temperature 3. Pressure 4. Humidity 5. Concentration EO: Common cycle time 2.5 hours (not including aeration time) EO: Items that CAN be sterilized (3) 1. Critical items that are heat, pressure, and moisture sensitive 2. Semi-critical items that are heat, pressure, and moisture sensitive 3. Devices with long lumens EO: Items that CANNOT be sterilized Trays with silicone mats (must follow manufacturer's guidelines) EO: Biological Indicator Bacillus Atrophaeus Gas Plasma: Method of Killing Interferes with microorganism metabolism by compromising essential components (enzymes, nucleic acid, etc.) Gas Plasma: Sterilant Used Combination of hydrogen peroxide vapor and gas plasma Gas Plasma: Parameters (3) 1. Time 2. Temperature 3. Hydrogen Peroxide Gas Plasma Gas Plasma: Common cycle time 55 min, 113°F
