ATP (NEW) QUESTIONS AND ANSWERS

What is the best mode of transmission for an EADL that controls a distant device such as a garage door opener? - Answer-EADLs are electronic aids to daily living. All of the listed answers are possible modes of transmission. However, radio frequency transmission (D) is the best choice for use with distant devices like garage door openers because it is not impeded by most materials except for grounded metal. Many more functions can be controlled when using house wiring (A), but it has several disadvantages in this case, including lack of portability and privacy. Both ultrasonic (B) and infrared (C) types are fairly portable, but in each case there must be a direct path between transmitter and receiver, as most materials block their signals. What is the main difference between the RESNA Code of Ethics and the RESNA Standards of Practice for Assistive Technology Practitioners and Suppliers? - Answer-The RESNA Code of Ethics lists specific modes of moral conduct to be adhered to; it includes a statement about informing and educating the public about assistive technology, in addition to statements related to moral conduct that other disciplines use. (A) is incorrect because the Standards of Practice actually is broader in scope that the Code. (B) is wrong because both are specific to the Assistive Technology field, although many of the standards are similar to those given in other medical standards of practice statements. (D) is incorrect since neither document actually outlines a specific quality assurance program. What is the threshold for a person being tested by pure tone audiometry? - Answer-In pure tone audiometry, thresholds are generally determined at frequencies ranging from 0.125 to 8 kHz as the intensity in dB that the person hears each tone 50 percent of the time in each ear. Decibels represent the amplitude of sound. Intensity (A) also represents a threshold in terms of the frequency of audible sound; that is not the meaning of "threshold" in pure tone audiometry, but the test does give an idea of the range of audible frequencies. Option (C) is one threshold for a normal individual without hearing loss. Option (D) is what is evaluated in another ass
