Nuclear Medicine Exit Exam Practice (2024-2025) Questions
WITH Answers
According to the NRC regulations, which of the following
signs should be posted in unrestricted areas?
A. Caution: Radiation Area
B. Authorized Personnel Only
C. Caution: Radioactive Materials
D. No posting is required - <<<Answers>>>>D. No posting is
required
Unrestricted area is an area in which an individual could
receive from an external source a maximum dose of 2 mrem
(20 uSv)/h, and access to the area is neither limited nor
controlled by the licensee.
The technologist responsibilities during radiopharmaceutical
administration for a cisternogram include:
A. Performing the lumbar puncture
,B. Ensuring that personnel and the surroundings are not
contaminated with radioactivity
C. Monitoring the patient for any adverse reactions to the
procedure
D. Obtaining consent to perform the procedure -
<<<Answers>>>>B. Ensuring that personnel and the
surroundings are not contaminated with radioactivity
Frequently, the radiopharmaceutical for cisternography is
administered outside the nuclear medicine department.
Therefore the technologist should ensure that any
contaminated material used during the lumbar puncture are
collected for proper disposal. The administration area and any
personnel who handled the radiopharmaceutical should be
monitored for contamination before they are permitted to
leave the area.
If a dose calibrator test begins by assaying 50 mCi of 99mTc-
pertechnetate, for how long should the test be carried out?
A. 66 hours
B. 72 hours
C. 24 hours
D. 48 hours - <<<Answers>>>>A. 66 hours
,The standard of practice calls for a dose calibrator linearity
test to be carried out until the original activity is decayed to 30
uCi or less. If the test begins with 50 mCi, it will take 11 half-
lives or 66 hours for the original activity to decay to 30 uCi.
Most well counters measure radioactivity by use of:
A. A silver halide layer
B. Thermoluminescent crystals
C. An applied voltage from anode to cathode
D. A sodium iodide crystal - <<<Answers>>>>D. A sodium
iodide crystal
A sodium iodide well counter is used for determination of
radioactivity, usually in disintegrations per minute (dpm),
from wipe tests and leak tests.
The mainstream of X-ray photons generated in the X-ray tube
is described as:
A. Braking radiation
B. Compton scattering
C. Attenuation photons
D. Characteristic radiation -
, determined by the levels (characteristic X-rays).
<<<Answers>>>>A. Braking radiation
Almost all of the X-rays produced by the X-ray tube are
bremsstrahlung, or braking, radiation. If the bombarding
electrons have sufficient energy, they can knock an electron
shell of the target metal atoms, and as a result, electrons from
higher states drop down to fill the vacancy, emitting X-ray
photons of precise energies
List mode acquisitions are:
A. A closed loop movie
B. A serial acquisition mode
C. A filter for heart rate variations
D. A temporary storage for acquired data -
<<<Answers>>>>B. A serial acquisition mode
In the list-mode, digitized X and Y signals are coded with
"time marks" as they are received in sequence in time, and are
stored as individual events in the order they occur.
Static bone imaging is performed several hours after tracer
administration to permit:
