1. Which patient-care action is most important before beginning an MRI
examination?
A. Select the post-processing method
B. Verify the patient's identity and examination order
C. Adjust the reconstruction matrix
D. Calculate the echo train length
Correct Answer: B. Verify the patient's identity and examination order
Correct patient identification and verification of the requested examination help
prevent wrong-patient and wrong-examination errors and are fundamental
components of safe MRI practice.
2. A patient asks why a particular MRI examination has been ordered. What is
the most appropriate technologist response?
A. Provide an explanation of the procedure and its general purpose within the
technologist's scope
B. Interpret the patient's images
C. Provide a definitive diagnosis
D. Change the examination based on the patient's preference
Correct Answer: A. Provide an explanation of the procedure and its general
purpose within the technologist's scope
,Technologists should educate patients about the procedure, preparation, expected
duration, and relevant risks while avoiding interpretation or diagnosis outside
their professional scope.
3. Which communication technique is most appropriate when a patient has
limited proficiency in the language used by the MRI staff?
A. Speak only to the patient's accompanying family member
B. Use an appropriate qualified interpreter
C. Avoid explaining the examination
D. Ask the patient to sign the consent form without explanation
Correct Answer: B. Use an appropriate qualified interpreter
Qualified interpretation improves communication accuracy and helps ensure that
the patient understands relevant instructions and information.
4. Which action is part of a proper MRI time-out?
A. Confirming the correct patient and examination
B. Increasing the magnetic field strength
C. Selecting the reconstruction algorithm
D. Changing the patient's diagnosis
Correct Answer: A. Confirming the correct patient and examination
A time-out provides a final safety check before a procedure and can include
confirmation of patient identity, examination, and other relevant procedural
information.
5. What is the primary purpose of hand hygiene before patient contact?
A. Improve image contrast
B. Reduce transmission of microorganisms
C. Increase RF signal strength
D. Prevent gradient-induced nerve stimulation
,Correct Answer: B. Reduce transmission of microorganisms
Hand hygiene interrupts transmission of microorganisms and is a fundamental
component of infection prevention.
6. Which MRI patient is most likely to require additional assistance with
positioning and transfer?
A. A fully ambulatory adult with no limitations
B. A patient with significant mobility impairment
C. A patient who wears eyeglasses
D. A patient with normal gait
Correct Answer: B. A patient with significant mobility impairment
Patients with limited mobility may require appropriate transfer equipment and
assistance to reduce fall and musculoskeletal injury risks.
7. What is the primary concern when a patient experiences a severe allergic-like
reaction to contrast media?
A. Immediate recognition and appropriate emergency response
B. Increasing the scan duration
C. Continuing the examination without assessment
D. Repeating the contrast injection
Correct Answer: A. Immediate recognition and appropriate emergency response
Severe reactions can become life-threatening and require prompt recognition,
activation of emergency procedures, and appropriate medical intervention.
8. Which laboratory value is commonly reviewed when assessing renal function
before administration of gadolinium-based contrast?
A. eGFR
B. Hemoglobin A1c only
, C. Platelet count only
D. Serum sodium only
Correct Answer: A. eGFR
Estimated glomerular filtration rate provides information about kidney function
and may be relevant when determining the appropriateness of a gadolinium-
based contrast examination.
9. What is extravasation?
A. Leakage of injected contrast material into surrounding tissue
B. Entry of contrast directly into the spinal canal
C. Movement of the patient during imaging
D. Leakage of helium from the magnet
Correct Answer: A. Leakage of injected contrast material into surrounding tissue
Extravasation occurs when contrast escapes from the vascular system into
surrounding tissue during or after injection.
10. Which MRI safety classification indicates that an item poses an unacceptable
hazard in the MR environment?
A. MR Safe
B. MR Conditional
C. MR Unsafe
D. MR Limited
Correct Answer: C. MR Unsafe
MR Unsafe identifies an item that should not be introduced into the MR
environment because it presents an unacceptable hazard under the applicable
classification.
11. What is the primary MRI hazard associated with a strongly ferromagnetic
object?
