CORRECT ANSWERS GRADED A+ ALL
AREAS COVERED
A
Platelets are small cell fragments that do not contain a nucleus and are responsible
for the plug that forms a puncture site.
The platelets found in blood are small...
a. Cell fragments necessary for blood coagulation
b. Toxins that are removed by the blood
c. Cells responsible for fighting infection
d. None of the above
A
What is indicated by the arrow in the image?
a. Brachiocephalic artery
b. Right subclavian artery
c. Right common carotid artery
d. Left subclavian artery
,C
The prothrombin is a test to evaluate the coagulation response of a patient and
normally ranges between 10-12 seconds.
Normal prothrombin time should range between ___________ seconds.
a. 3-5 seconds
b. 7-9 seconds
c. 10-12 seconds
d. 14-18 seconds
B
The time required for this injection would be 100 seconds. The total injection time
is found by dividing the contrast volume by the flow rate.
An automatic injector is set at 1.5 mL/sec injection rate. What is the injection time
for a contrast volume of 150 mL?
a. 120 seconds
b. 100 seconds
c. 90 seconds
d. 60 seconds
,A
The brachial artery would not be used for the administration of contrast.
Which of the following would not be used as a site for the injection of iodinated
contrast material?
a. brachial artery
b. cephalic vein
c. antecubital vein
d. basilic vein
C
To accurately recognize a dissecting aortic aneurysm the use of iodinated contrast
media is vital. The contrast outlines the wall of the aorta and improves the
visibility of any division within it.
To accurately demonstrate _____________________ the use of intravenous
iodinated contrast media during a CT study of the chest would be required.
a. Sarcoidosis
b. A solitary pulmonary nodule
c. A dissecting aortic aneurysm
d. Pneumonia
, A
Which of the following scan parameters should NOT be used for a three-
dimensional disarticulation study of the hip?
1 to 2 mm section width
(SFOV) Small scan field of view
Overlapping sections
a. (SFOV) Small scan field of view
b. 1 to 2 mm section width
c. Overlapping sections
False
kV controls the voltage potential between the tube cathode and the anode. This
controls the energy level of the electron beam which in turn controls the energy
level of the resulting x-ray photons. mA or tube current controls the filament
current which controls the temperature of the cathode filament from which the
electron beam is emitted.
mA is the voltage potential between the tube cathode and the anode while kV
controls the filament current and the temperature of the cathode filament.
True
False
