COMPREHENSIVE RADIOGRAPHY HESI TEST #2
UPDATED ACTUAL QUESTIONS AND CORRECT
ANSWERS
Question:

likely to be pro-duced when the projectile electron interacts with a bound
electron in which shell?
Answer:
K Shell
Question:
Which is the best projection to evaluate the coronoid process in profile?
Answer:
Medial oblique elbow
Question:
Under which condition might an x-ray photon be deviated from its original
direction?
Answer:
interaction occurs
Question:
In which way can the radiographer minimize motion due to peristalsis?
Answer:
Decrease exposure time
Question:
How much compensation is needed for a change to a small focal spot?
Answer:
None
Question:
A radiographer critiques an anteroposterior (AP) ankle projection. The medial
mortise joint is open while the lateral mortise joint is closed. How can the
radiographer adjust the ankle to correct this image?
Answer:
No correction needed
Question:
Which position of the elbow will clearly demonstrate the radial neck free of
ulnar superimposition?
Answer:
Lateral oblique
Question:
If a transformer has a greater number of turns in the secondary coil than in
the primary coil, how will the output voltage be affected?
Answer:
Increased
,Question:
A patient with a history of stroke and hemi-paralysis is transported to the
x-ray de-
partment by wheelchair. Which action should be first taken by the
radiographer?
Answer:
Place the patient's strong side next to the table
Question:
There are several methods to overcome sagging of the lumbar spine in the
lateral position. Where should the radiographer begin?
Answer:
Assessing the line connecting the spinous processes relative to the tabletop
Question:
If 7 milliampere-seconds (mAs) provides optimal exposure without a grid,
which mAs should be used with a 12:1 grid?
Answer:
35
Question:
A breathing technique is planned for a right anterior oblique (RAO) sternum
radiograph. The intended exposure is 50 milliampere-seconds (mAs) at 75
kilovolts peak (kVp) at 100 centimeter source to image receptor distance (SID).
Which milliampere (mA) station is preferred, assuming the radiographer
ensures exposure occurs during the act of inspiration?
Answer:
50
Question:
During an esophagram, which action may demonstrate esophageal varices?
Answer:
Instruct the patient to do the Valsalva maneuver
Question:
For a lateral femur, if a patient is rotated too far anteriorly, what will happen
to the condyles on the distal femur?
Answer:
Medial condyle will be anterior to the lateral condyle
Question:
Which term refers to unwanted fluctuations in the brightness of an image?
Answer:
Noise
Question:
Which factor would the radiographer choose to maximize spatial resolution in
the image?
Answer:
Small focal spot
, Question:
According to "Merrill's Atlas," where should the central ray (CR) be centered to
best demonstrate the rami for a posteroanterior (PA) mandible projection?
Answer:
The acanthion
Question:
A patient with a wound infection caused by methicillin resistant
staphylococcus aureus (MRSA) should be placed under which type of
precaution?
Answer:
Contact
Question:
If a patient contracts an infectious microorganism from soiled linen, which
term refers to this method of disease transmission?
Answer:
Fomite
Question:
Fetal exposure, in excess of which level, warrants possible termination of a
pregnancy?
Answer:
250 mGy
Question:
On a radiograph of a shoulder, the greater tubercle is visualized in profile.
Which projection was taken?
Answer:
Anteroposterior (AP), external rotation
Question:
Which projection is the freest of bony super-imposition over the
temporomandibular joint (TMJ)?
Answer:
Axiolateral (Schuller)
Question:
Which central ray angulation is recommended to prevent foreshortening of
the sacrum on an anteroposterior (AP) projection?
Answer:
15 degrees cephalad
Question:
A patient with which condition is most at risk for complications related to
intravenous contrast administration?
Answer:
Renal failure
Question:
What would a continuous, fine, horizontal white line across the computed
radiography image indicate?
