NOMAD Quiz Questions And Answers

The smaller diameter cone of the NOMAD Pro 2 combined with the use of DC power and primary shielding greatly reduce a patient X-ray exposure. - ANS True X-ray locks in NOMAD Pro 2 automatically engage after 2 hours of inactivity. - ANS False 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 The NOMAD Pro 2 should be routinely cleaned using disinfectant wipes, or some other non-acetone cleaner to maintain cleanliness. - ANS True The backscatter shield is adjustable to accommodate positioning devices and other special needs but if the backscatter shield is adjusted additional precautions are required. - ANS True If the NOMAD Pro 2 has been dropped, it should be returned to Aribex for an evaluation. - ANS True An exposure can be prematurely terminated for any reason by releasing the trigger at any time during the exposure. - ANS True The NOMAD Pro 2 should normally be held with two hands for stability whenever possible. - ANS True The Handset can be left on the Charging Cradle after reaching a full charge without harming the batteries. - ANS False The Handset should be detached from the NOMAD Pro 2 at the end of each day's use. - ANS True Radiation safety requires that we establish an in-house radiation protection program that complies with all applicable regulations and addresses precautions for patient and operators who have or may have which of the following medical conditions? - ANS Pregnancy In order to maintain the optimal operator safety zone the backscatter 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 - ANS a, c The duty cycle ( or rest period between exposures) to protect your NOMAD Pro 2 is as follows: a) 6 seconds for an exposure 0.09 seconds long b) 12 seconds for an exposure. 20 seconds long c) 24 seconds for an exposure 0.40 seconds long d) 45 seconds for an exposure 1.00 second long - ANS a, b, c Radiation safety is a 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 backscatter 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. - ANS a, b, c, d Which of the following are factors that would require increased exposure time when using the NOMAD Pro 2? a) film speed b) imaging sensors c) operator skill, knowledge and techniques d) patient mass - ANS All listed
