◉ How should a radiographer increase the stability of the base of
support?
A. Hold heavy objects close to body.
B. Stand with feet a greater distance apart.
C. Stand on one foot.
D. Keep back straight and knees bent.

a greater distance apart.
◉ A radiographer prepares to transfer a patient from a wheelchair
to the x-ray table. The patient recently suffered a stroke, exhibits
left-sided weakness, and is able to bear some weight. How should
the radiographer move the patient to the table?
,A. Use a hydraulic lift.
B. Position the left side of the wheelchair next to the table.
C. Position the right side of the wheelchair next to the table.
D. Have one radiographer lift the torso while another lifts the feet.
Answer: C. Position the right side of the wheelchair next to the table.
Because the patient's strongest side is the right side, the
radiographer should position the right side of the wheelchair next to
the table.
◉ What does "ventricular fibrillation" mean?
A. Premature ventricular contractions.
B. Slow heart rate.
C. Rapid heart rate.
D. Erratically quivering ventricles
Answer: D. Erratically quivering ventricles
Ventricular fibrillation means that the ventricles are quivering which
results in the heart's inability to pump blood.
◉ A patient in the radiology department suddenly develops a
nosebleed. The radiographer instructs the patient to lean forward
,and pinch the affected nostril against the midline nasal cartilage, but
the bleeding does not stop. What should the radiographer do next?
A. Instruct the patient to tilt the head back.
B. Transport the patient to the emergency room.
C. Apply a moist compress.
D. Place the patient in a recumbent position.
Answer: C. Apply a moist compress.
If gentle pressure is unsuccessful, the patient should apply a moist
compress. A patient should never be instructed to tilt the head back
or be placed in the recumbent position as the patient may aspirate
the blood.
◉ 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.
◉ Which rule is followed when examining unconscious patients?
A. Proceed as if the patient were conscious, asking questions 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.
Answer: 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.
◉ What should the radiographer do if a radiologist's instructions are
unclear?
A. Ask for clarification
