HESI Radiography Exam Questions and
Answers Top Rated A+ Latest Version
Question >> 1
Which is the best approach for speaking to a patient with a hearing impairment?
A. Ask patient to adjust hearing aid volume.
B. Do not make eye contact.
C. Speak in a low register.
D. Talk very slowly.
Answer>>
C. Speak in a low register.
Patients with hearing loss most often have difficulty hearing voices in a high register,
so speaking in a low register is recommended. Speaking at a moderate pace is
preferable, rather than very slowly.
Question >> 2
Which aspect of electrical power is responsible for accelerating electrons in an x-ray
tube?
A. Current flow
Page 1 of 107
,B. Resistive heat
C. Total wattage
D. Potential difference
Answer>>
D. Potential difference
Selected kVp, also known as potential difference, accelerates electrons crossing an x-
ray tube.
Question >> 3
In a properly positioned oblique lumbar spine radiograph, what makes up the "body"
of the "Scotty dog?"
A. Pedicle
B. Pars interarticularis
C. Lamina
D. Superior articular process
Answer>>
C. Lamina
The lamina is the body while the pars interarticularis represents the neck. The pedicle
is the eye of the Scotty dog. The ear is the superior articular process.
Question >> 4

,Which steps increase contrast in fluoroscopy? (Select the two that apply.)
A. Increase kVp
B. Use a smaller collimator field
C. Use a larger collimator field
D. Increase mA
E. Reduce kVp
Answer>>
B. Use a smaller collimator field
E. Reduce kVp
Using a smaller collimator field increases contrast, by reducing scatter and secondary
radiation production, and thus reducing fog. Reducing kVp increases contrast, at the
risk of lowered penetration.
Question >> 5
Which rule is followed when examining unconscious patients?
A. Proceed as if the patient were conscious, asking Question >>s and giving
instructions.
B. Remain as quiet as possible to avoid waking the patient during the exam.
C. Speak openly in front of the patient, since they cannot hear or understand you.
D. Avoid saying things you would not say to a conscious patient.

, D. Avoid saying things you would not say to a conscious patient.
Unconscious patients may retain the ability to hear and remember what is said, so it is
appropriate to avoid making statements that you would not make if they were
conscious.
Question >> 6
What is the longest field size dimension allowable for 10 inches by 12 inches
collimation at a 40 inch source to image distance (SID)?
A. 10.6 inches
B. 13.2 inches
C. 12.8 inches
D. 11.4 inches
Answer>>
C. 12.8 inches
Field size may be off +/- 2% of the SID, which in this case is 0.8 inches. 12.8 inches is in
the acceptable range.
Question >> 7
An anteroposterior (AP) oblique mortise joint projection demonstrates the distal fibula
without talar superimposition and an open talofibular joint. What should the
