Domain IV A&B Flashcards
_____ is a substance that inhibits the growth of bacteria this term is often used to describe hand washing or wound cleansing procedures.
Antiseptic
Where are barriers placed when taking radiographs?
Computer mouse, sensor, PID, control panel, and head rest.
What PPE’s are required for taking radiographs?
Protective glass, double mask, gloves, and protective clothing.
_____ is a microorganism capable of a causing disease.
Pathogen
What is the procedure to clean the room after the patient leaves?
Before dismissing the patient, remove the apron from the patient, hang it back up, unglove then wash hands, unmask and take glasses off. Once returned to the room, re-glove and re-mask. Take all barriers off. Wipe-discard-wipe.
Infection Control Procedures Used AFTER Exposure.
Disposal of contaminated items, must be disposed of following local and state environment regulations. Must be discarded while the radiographer is still wearing gloves. Beam Alignment devices, while still wearing gloves must remove the contaminated beam alignment devices from the treatment area and place them in an area designed for contaminated instruments. Hand hygiene, after removal and disposal of all contaminated items, must remove gloves and discard them, hands must be washed with water and soap. Lead Apron removal, after hand hygiene is done, remove from the patient. Surface disinfection, any uncovered areas that were contaminated during treatment must be cleaned and disinfected using an intermediate level disinfectant and utility gloves.
True or False. Hepatitis C virus (HCV) is a pathogen.
True
Infection Control Procedures Used for Digital Imaging.
Wired sensors; completely over the senors and the wired connection with plastic covering. After exposures are done, remove the plastic covering and wipe the sensor with disinfectant approved by the imagine manufacturer.
What does the patient need to wear while getting x-rays taken?
Lead apron WITH thyroid collar if taking intraoral radiographs, lead apron WITHOUT if taking extraoral radiographs.
Infection Control Procedure Used DURING Exposure.
Drying of exposed receptors after each acceptor has been placed in the patient’s mouth exposed to radiation and removed it must be dried. Collection of exposed receptors each receptor must be placed in a disposable container labeled with the patient’s name. Beam alignment devices should be transferred from the covered work area to the patient’s mouth and then back to the same area. interruptions during exposure if the operator needs to leave the room, must remove the gloves and wash hands before leaving.
Infection Control Procedure Used BEFORE Exposure.
Preparation of treatment area, supplies and equipment, patient, and radiographer.
What is the difference between sterilization and disinfection of instruments?
Critical instruments used to penetrate soft tissue or bone are considered critical and must be sterilized after each use. EX: forceps, burs and chisels.
Semi Critical instruments instruments that contact but do not penetrate soft tissue or bone, must be sterilized after each use. EX: beam alignment devices.
Non Critical instruments do not come in contact with mucous membranes. Intermediate-level or low-level infection techniques are required for their care between patients. EX PID, exposure button, and x-ray tube.
What is the difference between Intermediate-level disinfectants and low-level disinfectants?
Intermediate-level are EPA registered chemical germicides labeled as both hospital disinfectants and tuberculocidal.
Low-level are EPA-registered chemical germicides that are label only as hospital disinfectants
When should hands be washed?
Before and after treating each patient (before glove removal and after glove removal), after gloves that may have torn or cut open. After contact with bare hands. Before leaving the dental operator. When hands are visibly soiled or contaminated.
Infection Control Procedure Used for Film Processing
Film transport; film contaminated with saliva must be placed in a labeled disposable container after exposure. The disposable container should never be touched by gloved hands. Only after removing gloves, washing hands, dismissing the patient, and cleaning the area should the dental radiographer carry the disposable container holding the contaminated films to the darkroom.
Darkroom supplies; paper towels and gloves which are necessary for handling films before they are processed, must be available in the darkroom. Paper envelopes, paper cups or film mounts labeled with the patient’s name, to hold files after processing and these also should be available in the darkroom.
Film handling with and without barrier envelopes; barrier envelopes helped him minimize contamination in the dark room.
Disinfection of dark room; dark room countertops and any areas touched by gloved hands must be disinfected with an EPA registered hospital grade intermediate level disinfectant.
Daylight Loader Procedures; placed a paper cup in the vinyl or non-powdered gloves in the daily loaded compartment. Please look container with contaminated films next to the cup. Close the daily lower lid and push hands through openings. Put on gloves. Take one contaminated film out of the container. Open film packets as described in film handling without barrier envelopes. The film to drop onto the process or film feed slot area do not touch a film with gloved hands dispose of film packet wrapping in the paper cup. After all film packets have been opened remove gloves and place them in the cup. Feed all unwrapped films into the processor. Remove hands from the daylight loader. Wash hands. Lift the daily loader lid to remove and discard the cup with contaminated wrappings in the container that held contaminated films. Label the film mount paper cup or envelope with the patients name and use it to collect processed films.
