Question 1
What is the primary MRI safety concern associated with a medication pump that
has not been identified?
A. Reduced patient hearing
B. Increased image contrast
C. Potential device malfunction or unintended medication delivery
D. Decreased examination time
Correct Answer: C. Potential device malfunction or unintended medication
delivery
Rationale: An unidentified medication pump may respond unpredictably to the
static magnetic field, gradient fields, or RF energy. Because pump malfunction can
cause interrupted, excessive, or otherwise unintended medication delivery, the
device must be positively identified and its MR status established before scanning.
Question 2
What does the MR Conditional designation mean for a medication pump?
A. It is safe in every MRI environment
B. It may be used only when specified MR conditions are satisfied
C. It must always be removed before MRI
D. It contains no magnetic materials
,Correct Answer: B. It may be used only when specified MR conditions are
satisfied
Rationale: MR Conditional means that the device has been demonstrated to be
safe only under defined conditions. These conditions can include field strength,
spatial gradient, operating mode, positioning, scan parameters, or other
restrictions.
Question 3
What should be done when the MRI safety status of a medication pump cannot
be established?
A. Treat the device as unsafe for the MR environment
B. Bring it into Zone IV for further testing
C. Assume it is MR Conditional
D. Scan it using the lowest available field strength
Correct Answer: A. Treat the device as unsafe for the MR environment
Rationale: Devices with unknown MR safety status should not be assumed to be
safe. FDA guidance states that devices without established MR safety information
should be treated as unsafe until their status and conditions of use are verified.

Question 4
Which MRI field can exert force or torque on susceptible components of a
medication pump?
A. Static magnetic field
B. Acoustic field
C. Visible light field
D. Thermal field
Correct Answer: A. Static magnetic field
,Rationale: The static magnetic field can interact with ferromagnetic or
magnetically susceptible components, potentially producing displacement forces
or torque. The effect depends on the device design and its MR labeling.
Question 5
Why can RF energy be relevant to medication pump safety during MRI?
A. It can increase the patient's body weight
B. It can alter the scanner's room lighting
C. It can cause heating of certain device components
D. It eliminates magnetic attraction
Correct Answer: C. It can cause heating of certain device components
Rationale: RF energy can induce heating in conductive structures or components.
Device-specific MR conditions are established to limit potential heating and other
hazards.
Question 6
What is a major clinical concern when MRI temporarily interrupts delivery from
an implanted medication pump?
A. Improved drug absorption
B. Loss of intended therapy
C. Increased image resolution
D. Reduced magnetic susceptibility
Correct Answer: B. Loss of intended therapy
Rationale: If a pump temporarily stops or changes its delivery during MRI, the
patient may receive less medication than intended. The clinical consequences
depend on the medication and the patient's dependence on continuous therapy.
Question 7
, Which medication is particularly important when considering interruption of an
implanted infusion pump because abrupt withdrawal can be dangerous?
A. Baclofen
B. Oral vitamin C
C. Topical moisturizer
D. Saline used for routine skin cleansing
Correct Answer: A. Baclofen
Rationale: Intrathecal baclofen therapy may be delivered by an implanted pump.
Abrupt interruption can produce severe withdrawal, making appropriate MRI
planning and post-MRI pump evaluation particularly important. (Coding Source)
Question 8
What is an important concern after MRI exposure of certain programmable
implanted infusion pumps?
A. The pump may fail to resume expected operation
B. The patient automatically develops an MRI artifact
C. The scanner loses its magnetic field permanently
D. The pump reservoir becomes sterile
Correct Answer: A. The pump may fail to resume expected operation
Rationale: Some implanted infusion pumps may temporarily stop during MRI and
may not restart as expected after the examination. Therefore, appropriate post-
MRI evaluation is required for devices for which this is a known risk. (Coding

Question 9
What is the purpose of identifying the exact medication pump model before MRI?
A. To determine the patient's preferred imaging position
B. To determine the device-specific MR conditions
