EXAM WITH CORRECT ACTUAL
QUESTIONS AND CORRECTLY WELL
DEFINED ANSWERS LATEST ALREADY
GRADED A+ 2026
Which pathologic condition requires a reduction in exposure
factors to produce an acceptable image?
A. Emphysema
B. Late stage Paget's disease
C. Congestive heart failure
D. Atelectasis - ANSWERS-A. Emphysema
Emphysema is considered a destructive disease which
requires a reduction in exposure factors.
,When film-screen technology is used, which kilovolts-peak
(kVp) setting produces the best scale of contrast for imaging
ribs?
A. 100 kVp
B. 90 kVp
C. 80 kVp
D. 70 kVp - ANSWERS-D. 70 kVp
The lowest kVp of 70 provides the shortest scale of contrast.
Why should a radiographer routinely use a small focal spot
when imaging extremities?
A. Decrease in contrast.
B. Increase in recorded detail.
C. Decrease in patient dose.
D. Increase the life of the x-ray tube. - ANSWERS-B. Increase
in recorded detail.
A smaller focal spot decreases unsharpness and increases
recorded detail. This is important when imaging extremities.
,Which action can improve recorded detail?
A. Use the largest focal spot.
B. Select a larger kilovolts peak (kVp).
C. Increase the object-image receptor-distance (OID).
D. Increase the source-image receptor-distance (SID). -
ANSWERS-D. Increase the source-image receptor-distance
(SID).
Increasing the SID will cause an increase in recorded detail
on the image.
Which technique mimics the use of a grid?
A. Decreased source-image receptor-distance (SID).
B. Increased object-to-image-receptor-distance (OID).
C. Increased kilovolts peak (kVp).
D. Decreased milliampere-seconds (mAs). - ANSWERS-B.
Increased object-to-image-receptor-distance (OID).
, The air-gap technique, or increased OID, may be used to
reduce scatter radiation and thus, increase image contrast.
How can magnification of the heart be reduced when
performing a chest x-ray?
A. Use a 40-inch source-image-receptor-distance (SID).
B. Use a high kVp and low mAs technique.
C. Use the shortest possible exposure time.
D. Use a 72-inch source-image-receptor-distance (SID). -
ANSWERS-D. Use a 72-inch source-image-receptor-distance
(SID).
As the SID increases, magnification decreases. Therefore,
the radiographer should use a 72-inch SID.
What should the radiographer do if a radiologist's
instructions are unclear?
A. Ask for clarification
B. Question the lead technologist
C. Read the protocol book
