DMI 105 Jeopardy Exams Practice 2025 Questions and Answers This prime exposure factor primarily controls x-ray photon quantity ORRECT ANSWERmAs The speed and energy applied across the x-ray tube defines this prime exposure factor. - CORRECT ANSWER-KV This prime exposure factor primarily controls x-ray beam penotrability. - CORRECT A iRKV A 15% increase from 100 kV will result in this kilovoltage value. - CORRECT ANSWER- 115 This change should be made to kV when penetration is inadequate on an x-ray image. - CORRECT. ANSWER Increases A 15% increase from 60 kV will result in this kilovoltage value. - CORRECT ANSWER. 69 A 15% decrease from 70 kV will result in this kilovoltage value. - CORRECT ANSWER- 39.5 A 15% decrease from 85 kV will result in this kilovoltage value. - CORRECT ANSWER- 72.25 An exposure taken with control panel settings of 200 mA and 0.25 seconds will result in this mAs value. - CORRECT ANSWER3C Tf using the 15% rule, this change should be made to mAs if kV is decreased. - CORREC An exposure taken with control panel settings of 40 mAs and 0.20 seconds will result in this mA valuc. - CORRECT ANSWER-200 An cxposure taken with control panel scltings of 12 mAs and 100 mA will result in this time value. - CORRECT ANSWER-0.12 seconds An exposure taken with control panel settings of 30 mAs and 0.19 seconds will result in this mA value. - CORRECT ANSWER-300 When comparing 40" SID and 72" SID, this one will result in greater x-ray beam intensity. - CORRECT. ANSWER-40 If distance is doubled from 40" to 80", this fraction describes the reduction in x-ray beam intensity. - CORRECT ANSWER-1/4 Tf50 mAs is obtained using 500 mA and 0.10 seconds, what time should be set if 50 mAs is requested with an mA setting of 100?- CORRECT ANSWER-05 s Tf 15 mAs is obtained using 100 mA and 0.15 seconds, what time should be set if 15 mAs is requested with an mA setting of 50? - CORRECT ANSWER-D.3 s Tf 100 mAs is obtained using 400 mA and 0.23 seconds, what mA should be set if 100 mAs is requested with a time of 0.50 seconds? - CORRECT ANSWER-200 mA An acceptable radiograph of the cervical spine is taken using 79 kV, 20 mAs anda distance of 72” SID. If the SID is decreased to 40", what new mAs should be used to produce an acceptable radiograph? - CORRECT ANSWER-6.1 mAs An acceptable radiograph of the abdomen is taken using 80 kV, 40 mAs and a distance of 40" SID. If the SID is increased to 45", what new mAs should be used to produce an 30.5 mAs acceptable radiograph’? - ( An exposure of 200 mA and 80 kV has been selected for an AP projection of the abdomen using AEC. If 100 ms has been selected as the backup time, what will be the maximum possible exposure? - CORRECT ANSWER-What is 20 mAs? 109 milliseconds = 9.1 seconds 200 mA x 0.1 =20 Tf55 kV and 4 mAs were used for an exposure, what new mAs is required at 63 kV to T ANSWER2 mAs A radiograph of the chest is produced using 123 kV and 4 mAs. If the kV is decreased to 106 kV, what new mAs should be used to maintain exposure? - CORRECT ANSWER-8 mAs When comparing soft tissue and bone, this structure will have increased brightness on the When comparing soft tissue and bone, this structure will undergo more photoelectric Interactions. - CORRECT ANSWER-Bone When comparing a large adult patient to a thin adult patient, this one will result in more When comparing a 10 cm body part to a5 em body part, this one will require greater exposure factors. - CORRECT ANSWER 10 cm When comparing soft tissue and bone, this structure will attenuate more x-ray photons. - CORRECT ANSWER-Bone The thicker portion of the patient’s anatomy should be positioned under this end of the xray tube. - CORRECT ANSWERCathode The intensity at this end of the x-ray tube may be as much as 45 percent greater. - CORRECT ANSWERCalhode When imaging the thoracic spine, the patient's head should be at this end of the x-ray tube. - Ci NSWER-Anode This is the minimum total filtration required for x-ray tubes operating above 70 kV. - CORRECT ANSWER25 mm Al X-ray tube filtration consists of this metal. - CORR: ANSWER Aluminum X-ray photons with this energy level are removed with tube filtration. - CORRECT ANSWER-Low When comparing an increase and decrease in exposure factors, this change is required when a grid is used. - CORR! ANSWER increase When comparing overexposure and underexposure, this will occur ifa grid is used with no Grid use is recommended when body part thickness is grealor than this. - CORRECT ANSWER-10 cm Grids are used to prevent this from reaching the image receptor. - CORRECT ANSWER.
