Summary CIC prep In-class activity

CIC prep In-class activity Faculative anaerobe - utilizes oxygen if its present but can still grow without it Obligate anaerobes - can't survive with oxygen Incubation for scabies - typically 4 to 6 weeks but as short as 10 days IgM - primary immune response after exposure to a communicable disease pathogen or vaccine 2nd element of virulence - a mechanism for transmission to a new host Infection - entry of an infectious agent in the tissues of the host that multiplies and creates symptoms Contamination - presence of microorganisms on an inanimate object, on skin, or in substances Reservoir of the agent - where an organism can survive but may or may not multiply. Examples include humans animals insects food environment susceptible host - the host is susceptible to the disease lacking immunity of physical resistance to overcome the invasion by the pathogenic microorganism Virulence - ability to grow and multiply pathogenicity - ability to cause disease size of inoculum - the number of organisms needed to cause disease Colonization - presence of microorganisms in or on a host with growth but without tissue Invasion or damage Who gets green for a pneumococcal vaccine? - patients 65 years or older Most common flu isolate - A Most common regions in the US for Lyme disease - Mid-Atlantic, New England, Upper Midwest, Northern California What type of immunity does IgG mark? - long term mechanical barriers - skin, mucus, membranes, tears epidemiological triangle - host, agent, environment Sterilization - The process that completely destroys all microbial life, including spores. Baseline TST - = 10 mm is a positive result Baseline QFT TB test - positive Serial TST test - increase of =10 mm is positive Serial QFT test - change from negative to positive Known exposure TST test - =5 mm is positive if person had a baseline of 0 & =10 mm is considered a positive result in persons with a negative Baseline TST result or previous follow-up screening test results of =0 An assessment of internal validity and the influence of bias can be found in which section of a study? - discussion What should the abstract in a research study include? - the intent or objective of the study meta-analysis - study that combines the results of a large number of studies didactics - theory of teaching, and in a water sense, a theory and practical application of teaching and learning. refers to lectures that are overburdened with instructive or factual material What should you take into consideration When selecting new cleaning products? - ease of use & efficacy Water temperature that prevents the growth of Legionella - Hot- 124 degrees C & above Cold - 68 degrees C most reliable method of monitoring the effectiveness of environmental cleaning in a healthcare facility - environmental cultures using RODAC plates Who approves antiseptics? - The FDA elements of construction and renovation policy - phasing and commissioning of projects & Authority for determining unit closure issues hydrogen peroxide vapor unit - effective at disinfecting all services and supplies in the room What is the most critical factor in selecting a cleaning agent for use on patients care equipment? - the product should be selected based on the manufacturer's guidelines for cleaning the equipment How do you collect data for EVS process measures? - use a secret shopper to observe cleaning practices Which of the following recommendations should be made to reduce the risk of infection from sinks in patient care areas? - sink basins should be deep enough to prevent splashing of water onto nearby patient care items recommendations for a water feature in a healthcare facility - 1. the water feature should be designed so that water does not remain stagnant in any part of the feature, and should include built-in methods of filtering or disinfecting the water 2. the water feature should be designed to prevent aerolizing of water 3. the water feature must have routine maintenance What is an ICRA element related to building design features? - the number of Airborne infectious isolation rooms and where they will be located in the facility HCV prevention recommendations - 1. screening & testing of blood donors 2. risk-reduction counseling & screening of persons at risk for HCV 3. adherence to standard precautions & safe work practices Recommended vaccines for HCWs - HAV, HAB, flu, MMR, Tetanus, Pertussis, & Varicella if not immune Vaccine storage - vaccines should be placed in the central area of a unit, avoid placing vaccines on the top shelf, there must be enough room to store the year's largest inventory without crowding, a calibrated thermometer should be placed inside each storage unit, the storage unit must be dedicated to the storage of vaccines How long should a non-immune HCW who has direct contact with a patient with chickenpox be excluded from work duty? - from day 10 after exposure today 21 after exposure Which are acceptable methods for follow-up testing among HCW with unprotected exposure to TB? - 1. QFT-G testing of blood at the time of exposure & 12 weeks after exposure 2. TST via intradermal method at the time of exposure & 12 weeks after exposure 3. Chest radiograph of symptomatic personnel with positive TST or QFT-G results What should an IP recommend to the HR Director regarding employees born before 1957? - they are required to provide proof of immunity to measles mumps and rubella Staff assisting with bronchoscopy of a patient with suspected TB must wear which type of respiratory protection? - a fit tested respirator or powered air purifying respirator (PAPR) HBV postexposure prophylaxis for a HCW who has not completed vaccine series - complete series & provide HBV immunoglobin When are dialysis staff at most risk for exposure to bloodborne pathogens? - initiation and termination of dialysis & reprocessing, cleaning, and disinfection procedures Which type of thermometer should be used in a vaccine storage unit? - probe and glycol-filled bottle with an external monitoring device How long should a HCW who has developed the flu be excluded from work duties? - remain off work for 5 days or until symptoms have resolved, whichever is longer What type of TB testing is the best choice for a new employee who needs to be tested but has a history of BCG vaccination? - a IGRA blood test because prior BCG immunization does not cause a false positive with this test What department prepares an antibiogram? - Laboratory government agency over the safe medical device act - FDA The Joint Commission's five standards of infection prevention and control - 1. minimizing the risk for development of an HAI through organization-wide infection prevention program 2. identification of risk for the acquisition and transmission of infections agents
