considered to be water- soluble? (Select two)
Non-ionic
Non-
Low
ionic

Low
osmolar
What is the approximate osmolarity of blood and human serum?
10 milliosmoles/liter (mOsm/L)
300 milliosmoles/liter (mOsm/L)
40 milliosmoles/liter (mOsm/L)
300 milliosmoles/liter (mOsm/L)
1,500 milliosmoles/liter (mOsm/L)
Which of the following computed tomography (CT) contrast agents
are water- soluble? (Select three)
Metrizoate
Ioxaglate Metrizoate
Iohexol Ioxaglate
Barium
sulfate
Iohexol
, Compared to barium-sulfate suspensions that are prepared for
fluoroscopy, barium-sulfate suspensions that are prepared for
computed tomography (CT) are:
Less concentrated
Less

A blood-urea-nitrogen (BUN) of 11 milligrams per deciliter (mg/dL) is:
Within the normal range Below the normal
range Above the
normal range
Within the normal
range
Which two of the following tests may be used to evaluate a
patient’s renal function? (Select two)
Glomerular filtration rate
International normalized ratio
(GFR) Creatinine
(INR) Glomerular filtration
rate (GFR) Creatinine
Partial thromboplastin time (PTT)
Which three of the following medications are used to
decrease the likelihood of contrast reactions in patients with
Prednisone a known iodine allergy? (Select three)
Diphenhydramine (Benadryl)
Methylprednisolone (Solu-Medrol) Prednisone
Diphenhydramine
(Benadryl) Hydromorphone
(Dilaudid)
Methylprednisolone (Solu-
Medrol)
Injections of intravenous (IV) contrast through small veins in the
hands and wrists are avoided because these small veins are
too:
Small to tolerate pressure-injection
Small to be cannulated
Small to tolerate pressure-
injection Distal for
effective bolus tracking
Closely associated with surrounding arteries
How could the internal jugular line be used for intravenous (IV)
contrast injection in the following image?
No power injection allowed Power injection as labeled
