In a logarithmic scale, a 10 dB increase in intensity ________ the loudness over most of the audible range. - correct answer doubles The normal human ear can respond to a range of frequencies from about __________ - correct answer 20 to 20,000 Hz The concept of critical bands and frequency resolution contribute to our ability to - correct answer hear effectively in background noise and discriminate between two sounds that are very close in frequency T/F Low and extremely high frequencies require more intensity to be just barely audible as compared to the middle range of frequencies. - correct answer True T/F The hearing instrument specialist is legally and ethically obligated to practice infection control standards that are consistent with federal/national and local jurisdictional safety laws and/or guidelines. - correct answer True In the context of infection control "standard precautions" refers to: - correct answer a set of infection control practices designed to prevent the transmission of disease "Work practice controls" are: - correct answer a written policy that outlines specific procedures that must be performed to minimize the spread of disease At a minimum gloves must be worn when: - correct answer accepting a hearing instrument from a patient/client and removing an ear impression Cleaning, disinfecting, and sterilization differ as follows: - correct answer cleaning does not kill germs; disinfecting kills germs; sterilization kills 100% of the germs plus endospores A family member brings another's hearing instrument for service and the aid is placed on the surface of the workbench. It is caked with debris, presumably cerumen, and needs extensive cleaning. Bits of material fall all over the workbench. After addressing the concerns about the hearing instrument: - correct answer the touch surface is cleaned and disinfected Cold sterilization involves: - correct answer soaking cleaned critical instruments in an approved and appropriate chemical for the number of hours specified Examples of semi-critical instruments are: - correct answer otoscope specula; reusable earmolds or eartips; cerumen removal instruments T/F It is necessary to perform hand hygiene procedures immediately after glove removal. - correct answer True Hand hygiene refers to: - correct answer washing hands with soap and the use of alchohol-based hand sanitizers The fleshy part of the ear that protrudes from the side of the head is called the - correct answer auricle or pinna The average adult's ear canal is about ______ inch in length and about ______ inch in diameter. - correct answer 1 and 1/4 An important ear canal landmark for ear impressions is the: - correct answer second bend The cone of light is: - correct answer a reflection of the light from an otoscope on the tympanic membrane The external auditory canal's resonant frequency is: - correct answer about 2700 Hz and varies slightly from person to person The normal tympanic membrane has a typical appearance characterized as: - correct answer pearly grayish and oval The structure of the tympanic membrane is made up of: - correct answer 4 layers Splash surface - correct answer Any patient/client-care surface that may be potentially hit with blood, bodily fluids, saliva, or other secretions. Vectorborne transmission - correct answer Occurs via an animal or insect that can transmit the disease from an infected individual to another person. Indirect contact transmission - correct answer Occurs when an infected person or object touches a surface and then another person touches that surface. Disinfecting - correct answer Process whereby germs are killed Non-critical items - correct answer Items that contact only intact skin or do not directly touch patients/clients. Items that contact only intact skin or do not directly touch patients/clients. - correct answer Cleaning and low-level disinfection Level of processing necessary for critical items - correct answer Cleaning and then sterilization Hand hygiene - correct answer The single most important precaution against the spread of disease Droplet contact transmission - correct answer Occurs when organisms are transferred via droplets from an infected person when they cough, sneeze, or talk to another person. Sterilization - correct answer Process whereby 100% of germs (including endospores) are killed. Touch surface - correct answer Any patient/client-care surface that may potentially come in direct or indirect contact with hands. High-level disinfection - correct answer Process the ensures elimination of most microorganisms. Vehicle transmission - correct answer Occurs when a contaminant is ingested or there is exposure to contaminated substances via food, water, blood, or bodily fluids. Level of processing necessary for semi-critical items - correct answer Cleaning and high-level disinfection at a minimum. Sterilization is preferred.
