NMTCB Nuclear Medicine Board Review
1. A well counter is set to collect 10,000 counts or to stop after 5 minutes.Thecounter stops at
2 minutes. What is the count rate (in cpm)?
a. 2,000
b. 5,000
c. 10,000
d. 20,000
e. 200,000: B
2. As the sample volume is increased, well counter counting efficiencies are:
a. Reduced
b. Improved
c. Unchanged
d. Increased to a point, then reduced.
e. Unpredictable: A
3. The action of the ACD solution in labeling RBCs for a red cell massdetermination is as
a(n):
a. Cell preservative
b. pH stabilizer
c. A reducing agent
d. Oxidizing agent
e. Anticoagulant: E
4. If a vial containing Tl-201 is found to have an activity of 10.0 mCi at 8 a.m. on Monday,
how much activity would remain at 10 a.m. on Friday provided no dose was drawn from this
vial (in mCi)?
a. 86.5
b. 4.03
c. 3.94
d. 3.10
e. 2.55: C
5. High Radiation Area signs are to be posted in areas where exposures greater than
mrem/hr are measured at 30 cm from the sourceor from any surface through which the
radiation penetrates:
, a. 5
b. 10
c. 50
d. 100
e. 500: D
6. When a zoom is used during a 64 x 64 byte mode computer acquisition:
a. The computer automatically switches to a larger matrix size
b. The field of view is increased
c. A spatial filter must be used to smooth away the adverse affects of thistechnique
d. Spatial resolution is increased
e. More computer memory is needed: D
7. Which of the following quality control tests should be performed on a dosecalibrator after a
power outage?
a. Nothing needs to be checked if QC was performed in the last 24 hours
b. Constancy
c. Linearity
d. Geometry
e. Sensitivity: B
8. When processing a gated blood pool study, incorrectly placing the back-ground region
over part of the aorta will have what effect on the resulting EFcalculation?
a. The result will be higher than patient's true EF
b. The result will be lower than patient's true EF
c. It will have no effect; the background in the region of the aorta is insignifi-cant
d. It will have no effect: the background data is only used to smooth theresulting volume
curve
e. It depends; the effect is different depending on whether the patient's heartfunction is
abnormal or normal to begin with: A
9. Once blood has been drawn in a syringe containing an anticoagulant, thenext step to be
done when labeling leukocytes with In-111 oxine is to:
a. Centrifuge the sample at 200 g. for 5 minutes
b. Centrifuge the sample at 2000 g. for 5 minutes
