LMRT Core Review QUESTIONS WITH CORRECT!! ANSWERS 202425 UPDATE

restrict the XR beam to the clinical area of interest - correct answer As a professional radiographer, the practice of ALARA requires you to prime - correct answer The factors that affect XR emission under the direct control of the radiographer are called_ factors beam quality - correct answer Milliamperage-second (mAs) directly affects all of the following EXCEPT mA & filtration - correct answer The factors that directly affect XR quantity are kVp & beam filtration - correct answer The factors that directly affect XR quality are 6.3 x 10(18) - correct answer If 1 coulomb is equal to 6.3 x 10(18) electron charges, how many electrons flow from cathode to anode 1 second 6.3 x 10(15) - correct answer If 1 ampere equals a flow of 6.3 x 10(18) electrons per second, how many electrons flow from cathode to anode in 1 milliampere? increase 2-fold - correct answer As the mA doubles, the number of electrons flowing from cathode to anode XR beam quantity - correct answer The product of tube current 7 exposure time is equal to change the mAs from 15-21 mAs - correct answer In order to increase radiographic film density by 40% the radiographer would directly proportional - correct answer The relationship between mAs & exposure is the reciprocity law - correct answer The reaction of a photographic film to light is equal to the product of the intensity of the light and the duration of the light exposure. cause the electrons to travel faster from cathode to anode - correct answer Increasing the kVp for an exposure will greater energy - correct answer Increasing the energy of an incident electron will result in the production of an XR photon with radiographic film density - correct answer Kilovoltage is the primary controlling factor of contrast - correct answer Adjustments in kVp should be used to control radiographic kVp - correct answer XR beam penetrability is primarily controlled by 400 mA, 200 ms, 40" SID - correct answer All factor remaining constant, which of the following set of exposure conditions would yield an image with GREATEST radiographic film density
