Which branch of the abdominal aorta arises below or up to 2 cm distal to the celiac trunk?
Inferior mesenteric artery.
Middle adrenal arteries.
Renal arteries.
Superior mesenteric artery. ✔✔ Superior mesenteric artery
The superior mesenteric artery arises from the abdominal aorta below or up to 2 cm distal to the celiac
trunk. It supplies blood to the small bowel, right colon, and middle colon.
The gastroduodenal artery is a branch of which of the following?
Common hepatic artery.
Splenic artery.
Left gastric artery.
Right gastroepiplotic artery. ✔✔ Common hepatic artery
The gastoduodenal artery is a branch of the common hepatic artery. The ability to locate and identify
the key blood vessels of the body is a vital skill for radiographic professionals, including those
performing vascular interventions
You review a patient's laboratory report. The values for the arterial blood gases (ABG) are listed. Which
of the following is a component that is measured as part of this laboratory test?
Oxygen saturation
Helium saturation
,Diode saturation
Water saturation ✔✔ Arterial blood gases (ABG) is a test that measures the amount of oxygen and
carbon dioxide in the blood and identifies the acidity or pH of the blood.
The following are elements measured in the ABG test: oxygen saturation (SaO2), partial pressure of
oxygen (PaO2), partial pressure of carbon dioxide (PaCO2), bicarbonate (HCO3), and the arterial blood's
pH
The normal ranges for these components are:
Bicarbonate (HCO3) - normal value limits are 22 - 28 mEq/L
Partial pressure of oxygen (PaO2) - normal value limits are 75 - 100 mmHg
Partial pressure of carbon dioxide (PaCO2) - normal value limits are 38 - 42 mmHg
Arterial blood pH - normal value limits are 7.35 - 7.45
Oxygen saturation (SaO2) - normal value limits are 94 - 100%
The ABG should be checked to assess for respiratory conditions or diseases that impacts the lungs.
Changes in pulmonary functioning can lead to conditions such as hypoxemia (insufficient amounts of
oxygen in the blood) or hypercapnia (too much carbon dioxide in the arterial blood).
Partial pressure of oxygen (PaO2) measuring less than 60 mm Hg may also indicate insufficient oxygen in
the blood. Then, oxygen saturation (SaO2) levels lower than 90% may reveal the lack of sufficient oxygen
in the body's tissues.
Which veins or arteries are used for a head angiogram?
Femoral artery.
Femoral vein.
Brachial vein.
,All of the above. ✔✔ All of the above
An angiogram of the head is done to check blood flow. It checks the blood vessels in the direct area of
the head. It uses both contrast material or iodine dye and fluoroscopy. Catheters are placed into either
the femoral artery or vein or the brachial artery or vein. The catheter is then moved up the vessel to the
head.
The inferior mesenteric artery arises from the aorta at what level?
T13-L1 interspace.
L4-L5 interspace.
L2-L3 interspace.
T11-T12 interspace. ✔✔ L2-L3 interspace
The inferior mesenteric artery arises from the aorta at the level of the L2-L3 interspace and descends
into the pelvis. Knowledge of anatomy and the position of organs and blood vessels is essential to
radiographic professionalism.
The clavicular artery supplies blood to which of the following?
Shoulder joint.
Deep neck muscles.
Anterior chest wall.
Subclavius. ✔✔ Subclavius
The clavicular artery is a branch of the thoracoacromial trunk. It supplies blood to both the subclavius
and the sternoclavicular joint.
The abdominal aorta bifurcates into which vessels?
, Common iliac arteries.
Ulnar and radial arteries.
External iliac arteries.
Superior and inferior mesenteric arteries. ✔✔ Common iliac arteries
The abdominal aorta bifurcates into the right and left common iliac arteries. The bifurcation occurs at
the L4 level. Knowledge of anatomy is an essential part of professionalism as a radiographer.
At what level are the kidneys located?
L2-L3.
T11-T12.
L4-L5.
T12-L3. ✔✔ T12-L3.
The kidneys are located at the T12 to L3 level. Knowledge of anatomy and the position of organs and
blood vessels is essential to radiographic professionalism
In digital subtraction imaging if you add a small amount of the mask back into the subtracted image, but
not enough to affect the image this is:
image re-masking
land marking
road mapping
temporal subtraction ✔✔ land marking
Inferior mesenteric artery.
Middle adrenal arteries.
Renal arteries.
Superior mesenteric artery. ✔✔ Superior mesenteric artery
The superior mesenteric artery arises from the abdominal aorta below or up to 2 cm distal to the celiac
