Nomad Exam Questions And Answers

T/F: An exposure can be prematurely terminated for any reason by releasing the trigger at any time during the exposure - ANS False Which of the following is FALSE? The duty cycle (rest period between exposures) to protect your NOMAD Pro 2 should be: A. 12 seconds for an exposure 0.20 seconds long B. 24 seconds for an exposure 0.40 seconds long C. 30 seconds for an exposure 0.50 seconds long D. 45 seconds for an exposure 1.0 second long - ANS D. 45 seconds for an exposure 1.0 second long The technique factor settings for making exposures: A. is represented in a chart in the Operator Manual that is for reference only in establishing and customized exposure technique for your office. B. will be affected by various factors, including the following: preference, technique, film or sensor speed, and patient mass. C. can be reprogrammed by the operator into the NOMAD Pro 2. D. is included on the CD in a blank format for creating a customized technique factor chart for your office. E. all of the above - ANS E. all of the above T/F: Some battery charge may be lost during extended inactivity (leading to fewer exposures between each handset charging session). - ANS True T/F: Because NOMAD Pro 2 shielding limits the exposure, it is permissible to have other people in the exam room during exposures without any precautions. - ANS False When using the NOMAD, the____________ state will be discontinued if no action is taken after __________ seconds. A. Enabling X-Rays, 15 B. Enabling X-Rays, 30 C. Ready, 15 D. Ready, 30 E. X-Rays ON, 30 - ANS C. Ready, 15 Illumination of the yellow LED on the control panel indicates: A. Nomad is ready to take an x-ray. B. X-ray exposure is being made. C. Battery is low. D. System failure has occurred. - ANS B. X-ray exposure is being made When there is not enough battery charge left to take an exposure, the charge indicator bars will fade away and the _____ alarm message will appear on the screen, and the NOMAD Pro 2 will not allow exposure to begin. A. Incomplete B. Recharge battery C. System Failure D. Handset Failure E. Locked - ANS B. Recharge battery T/F: The back scatter shield is adjustable to accommodate positioning devices and other special needs but if the back scatter shield is adjusted, additional precautions are required. - ANS True T/F: X-ray locks in NOMAD Pro 2 automatically engage after 2 hours of inactivity. - ANS False After the NOMAD Pro 2 is powered on, a single quick pull of the trigger will result in the _______ message appearing on the screen. The green LED will illuminate and then the _________ message will appear on the screen. A. Enabling X-rays, X-rays on B. X-rays on, Ready C. Ready, X-rays on D. Enabling X-rays, Ready E. Ready, Enabling X-rays - ANS D. T/F: When using the NOMAD, protection to the operator will be decreased if the back scatter shield is not parallel to the patient. - ANS False T/F: If the NOMAD Pro 2 has been dropped, it should be returned to Aribex for an evaluation. - ANS True T/F: The NOMAD Pro 2 should be normally held with 2 hands for stability whenever possible. - ANS True T/F: In order to maintain the optimal operator safety zone, the back scatter shield should be: A. Held so it is parallel to the operator. B. Slid back on the cone toward the operator. C. Held so NOMAD Pro 2 is positioned close to the patient. A and C All of the above - ANS A and C T/F: When the NOMAD Pro 2 is not in service, it is advisable to ensure that the device is securely stored and the x-rays are LOCKED so that unauthorized/unintended use or damage does not occur. - ANS True An alarm indicating a partial exposure (when the trigger was not depressed through the entire time setting, either on purpose or accidentally) is indicated by a series of beeps and the ________message on the screen until a button is pressed. A. Incomplete B. Ready C. System Failure D. Handset Failure E. Locked - ANS A. Incomplete Radiation safety is at the heart of the NOMAD Pro 2 design. The NOMAD Pro 2 has: A. Primary shielding to contain the x-ray beam as it is generated. B. Secondary shielding to direct back scatter radiation away from the operator when properly positioned. C. Shielding that results in an operator x-ray dose that is well below federal occupational limits when used correctly. D. Smaller cone and focal point diameter for reduced patient exposure and enhanced image quality. E. All of the above - ANS E. All of the above
