tremors, which demonstrate:
A. Reduced uptake in the putamen
B. Asymmetrical uptake in the basal ganglia
C. Gray matter uptake
D. Normal DAT binding - ANSWER-D. Normal DAT binding
123I-DaTscan imaging can differentiate parkinsonism syndromes from essential
tremors, which demonstrate normal DAT binding.
99mTc-Oxidronate image of the region shown would demonstrate all the following
structures except the:
A. Costochondral Junctions
B. Acromion processes
C. Sternum
D. Clavicles - ANSWER-B. Acromion processes
The image depicts an anterior view of the rib cage and proximal upper extremities. The
acromion processes would be demonstrated on a posterior view of the upper thorax that
includes the scapulae.
A 99mTc-medronate image of the region shown would best demonstrate which of the
following structures?
I. Iliac crests II. Distal Femur III.Ischium IV. Thoracic vertebrae 10-12
A. I and II only
B. III only
C. III and IV only
D. I,II, and IV only - ANSWER-D. I,II, and IV only
The image depicts a posterior view of the lower lumbar spine, the pelvis, and the
proximal femurs. The iliac crests would be demonstrated on an anterior view of the
,pelvis. The distal femurs and the 10th through 12th thoracic vertebrae are inferior and
superior, respectively, to the structures shown in the image.
A biohazard warning label would be found on all of the following except a:
A. Unit of blood released for clinical use
B. Contaminated sharps container
C. Refrigerator containing potentially infectious material
D. Receptacle for contaminated laundry - ANSWER-A. Unit of blood released for clinical
use
Biohazard warning labels are attached to any container of regulated materials. These
include refrigerators, freezers, and anything used to store, transfer, or ship blood or
infectious materials. Labels are not required on containers of blood that have been
released for clinical use, such as blood transfusions.
A common antecubital vein used for intravenous administration of a
radiopharmaceutical is the:
A. Cephalic
B. Ulnar
C. Radial
D. Brachial - ANSWER-A. Cephalic
A variety of antecubital veins can be used for drug administration. But the two most
commonly used are the basilic and cephalic veins.
A dose calibrator accuracy test may be performed with which of the following
radioactive sources?
A. 75 uCi 137Cs
B. 6 uCi 99mTc
C. 25 uCi 137Cs
D. 100 mCi 99mTc - ANSWER-A. 75 uCi 137Cs
Various long-lived sources can be used to test accuracy. At least 50 uCi of 137Cs,
57Co, or 133Ba should be used. 99mTc is not an appropriate choice because it's
relatively short-lived.
A dose calibrator is used to assay the amount of radioactivity in a sample before it is
administered to a patient. All radiation leaving the source placed in the dose calibrator is
detected EXCEPT radiation directed toward:
A. The hole at the top of the chamber
B. The bottom of the chamber
C. The upper part of the chamber
,D. The bottom half of the chamber - ANSWER-A. The hole at the top of the chamber
Since there is no radiation detecting material above the source i.e the hole in the top of
the chamber, the photons emitted through the top do not contribute to the dose reading.
A gated equilibrium ventricular function study can be performed with which of the
following 99mTc-labeled radiopharmaceuticals?
A. Pentetate
B. Medronate
C. Pyrophosphate
D. Human serum albumin - ANSWER-D. Human serum albumin
Gated equilibrium blood pool method is also referred to as multiple gated acquisition or
MUGA. Human serum albumin (HAS) labeled with 99mTc is another intravascular tracer
that has been used as a blood pool agent.
A locked storage closet next to the radiopharmacy containing phantoms and sealed
sources has a measured exposure rate of 3 mR/h. It should be posted with a sign
reading:
A. No posting required
B. Caution: Radioactive Materials
C. Caution: Radiation Area
D. Caution: High Radiation Area
E. Grave Danger: Very High Radiation Area - ANSWER-B. Caution: Radioactive
Material
-this sign is posted in areas or rooms in which 10 times the quantity of any license
material specified in Appendix C of 10CFR20 are used or stored. The limit at which a
Caution: Radiation Area is 5 mR/hr; high radiation areas and very high radiation areas
are a 100 mR/h and 500 rad/hr respectively.
A patient who becomes hypoglycemic may exhibit all the following signs and symptoms
except:
A. Weakness and shakiness
B. Irritability
C. Nausea and vomiting
D. Confusion - ANSWER-C. Nausea and vomiting
The onset of symptoms of hypoglycemia may be sudden and include general
weakness, sweating, clammy, cold skin, tremors, nervousness, irritability, hunger,
blurred vision and loss of consciousness. The condition can be remedied quickly with
the administration of sugar (3 pieces of candy or fruit juice)
, A patient with a chest tube arrives in the nuclear medicine department for an Imaging
study. The technologist should:
A. Cancel the procedure because the chest tube apparatus will interfere with the study
B. Place the chest tubes external apparatus on the Imaging table next to the patient
C.Hang the chest tubes external apparatus from an IV pole and raise it above the
patient's chest
D.Place the chest tubes external apparatus on a level lower than the patient's chest -
ANSWER-D. Place the chest tubes external apparatus on a level lower than the
patient's chest
for proper drainage, chest tube apparatus must always remain lower than the patient's
chest
