(B) 200 mA, 0.06 s
(C) 600 mA, 0.02 s
(D) 100 mA, 0.12 s - correct answer ✔✔600 mA, 0.02 s
,[t is essential to use the shortest possible exposure time in order to have a "stop action" effect.]
When green-sensitive rare earth screens are properly matched with the correct film, what type
of safelight should be used in the darkroom?
(A) Wratten 6B
(B) GBX or GS1
(C) Amber
(D) None - correct answer ✔✔GBX or GS1
[The GBX or GS1 is a red filter that is safe with green-sensitive film emulsion.]
Which of the following technical changes would best serve to remedy the effect of widely
different tissue densities?
(A) Use of high-speed screens
(B) Use of a high-ratio grid
(C) High-kVp exposure factors
(D) High-mAs exposure factors - correct answer ✔✔High-kVp Exposure Factors
Which of the following are methods of limiting the production of scattered radiation?
1. Using moderate-ratio grids
2. Using the prone position for abdominal exams
3. Restricting the field size to the smallest practical size
(A) 1 and 2 only
(B) 1 and 3 only
(C) 2 and 3 only
(D) 1, 2, and 3 - correct answer ✔✔Using the Prone Position for Abdominal Exams.
,Restricting The Field Size to the Smallest Practical Size.
The purpose of the automatic processor's circulation system is to
(A) monitor and adjust temperature.
(B) agitate, mix, and filter solutions.
(C) move the film and change its direction.
(D) monitor the solution and replace it as necessary. - correct answer ✔✔Agitate, Mix, and
Filter Solutions.
A quality assurance program serves to
1. keep patient dose to a minimum.
2. keep radiographic quality consistent.
3. ensure equipment efficiency.
(A) 1 only
(B) 1 and 2 only
(C) 1 and 3 only
(D) 1, 2, and 3 - correct answer ✔✔Keep Patient Dose to a Minimum.
Keep Radiographic Quality Consistent.
Ensure Equipment Efficiency.
Exposure factors of 90 kVp and 4 mAs are used for a particular nongrid exposure. What should
be the new mAs if an 8:1 grid is added?
(A) 8 mAs
(B) 12 mAs
(C) 16 mAs
, (D) 20 mAs
(Saia, p 328) - correct answer ✔✔16 mAs
[to change from nongrid to an 8:1 grid, multiply the original mAs by a factor of 4. A new mAs of
16 is required]
Which of the following is (are) classified as rare earth phosphors?
1. Lanthanum Oxybromide
2. Gadolinium Oxysulfide
3. Cesium Iodide
(A) 1 only
(B) 1 and 2 only
(C) 2 and 3 only
(D) 1, 2, and 3 - correct answer ✔✔Lanthanum Oxybromide
Gadolinium Oxysulfide
Which of the following pathologic conditions would require an increase in exposure factors?
(A) Pneumoperitoneum
(B) Obstructed bowel
(C) Renal colic
(D) Ascites - correct answer ✔✔Ascites
Which of the following is most likely to produce a radiograph with a long scale of contrast?
(A) Increased photon energy
(B) Increased screen speed
