NMT Exam 1 Questions With Correct
Answers
1. Before tracer administration, all of the following preparations are
| | | | | | | | | |
required for a 27-year old woman referred for total-body bone imaging
| | | | | | | | | | |
except:
a. removing attenuating materials from the patient
| | | | | |
b. answering the patient's questions
| | | |
c. ruling out pregnancy
| | |
d. explaining the procedure to the patient
| | | | | |
e. swab the injection site with alcohol
| | | | | |
a. removing attenuating materials from the patient
| | | | | |
not necessary to remove until just before imaging
| | | | | | |
,2. Which of the following structures normally appear as areas of
| | | | | | | | | | |
increased activity on the bone images of children?
| | | | | | |
a. diaphyses of the long bones
| | | | |
b. breast tissue
| |
c. lumbar spine and cranium
| | | |
d. costochondral joints and epiphyseal plates
| | | | |
e. metatarsals
|
d. costochondral joints and epiphyseal plates
| | | | |
these are areas of active bone growth in children
| | | | | | | |
3. If tracer concentration is visualized in the skeleton, stomach, thyroid,
| | | | | | | | | | |
and salivary glands on a bone image, the most likely explanation for
| | | | | | | | | | | |
these findings is that the:
| | | |
a. patient was imaged too soon after tracer administration
| | | | | | | |
b. patient's renal function is compromised
| | | | |
c. radiopharmaceutical contained excess free [Tc-99m] pertechnetate
| | | | | |
,d. incorrect radiopharmaceutical was administered
| | | |
e. radiopharmaceutical contained excess free [F-18] sodium
| | | | | |
c. radiopharmaceutical contained excess free [Tc-99m] pertechnetate
| | | | | |
if the RP was not properly compounded or came unbound, excess
| | | | | | | | | | |
pertechnetate will uptake in these organs | | | | |
4. For interpretation of nuclear medicine lung images, a chest X ray is
| | | | | | | | | | | | |
required to: |
a. rule out possible causes of the patient's symptoms
| | | | | | | |
b. determine cardiac size
| | |
c. rule out previous lung surgery
| | | | |
d. rule out a pulmonary embolus
| | | | |
e. rule in a pulmonary embolus
| | | | |
a. rule out possible causes of the patient's symptoms
| | | | | | | |
symptoms of PE are similar to other problems such as rib fracture, MI,
| | | | | | | | | | | | |
and pneumonia
|
, 5. The image shown here was obtained after the administration of [Tc-
| | | | | | | | | | |
99m] MAA. Which of the following is the most likely explanation for the
| | | | | | | | | | | | |
quality of this lung perfusion image?
| | | | |
a. The image shows lung pathology.
| | | | |
b. There is radioactive contamination on the patient's skin or the
| | | | | | | | | | |
camera detector. |
c. Blood clotted to MAA particles was injected intravenously.
| | | | | | | |
d. Too many MAA particles were administered to the patient.
| | | | | | | | |
e. A left to right shunt occurred in the heart.
| | | | | | | | |
c. Blood clotted to MAA particles was injected intravenously.
| | | | | | | |
blood was drawn back into the syringe and allowed to mix with MAA,
| | | | | | | | | | | | |
and the resulting clumps became trapped in the lung vasculature
| | | | | | | | |
Image: 5. The image shown here was obtained after the administration
| | | | | | | | | | |
of [Tc-99m] MAA. Which of the following is the most likely explanation
| | | | | | | | | | | |
for the quality of this lung perfusion image?
| | | | | | |
a. The image shows lung pathology.
| | | | |
b. There is radioactive contamination on the patient's skin or the
