automatic injector in 50 seconds. The flow rate for this injection is: - correct answer✔✔2.5
|| || || || || || || || || || || || || || ||
mL/sec
Flow rate may be calculated by dividing total contrast volume by time of injection.
|| || || || || || || || || || || || ||
The condition whereby the pt suffers from a low concentration of oxygen in the blood is
|| || || || || || || || || || || || || || || ||
called: - correct answer✔✔hypoxemia || || ||

||
3. race - correct answer✔✔1, 2, and 3
|| || || || || || ||
Which of the following IV contrast agent administration methods provides the greatest
|| || || || || || || || || || || ||
overall plasma iodine concentration?
|| || ||
a. drip infusion
|| ||
b. bolus technique
|| ||
c. biphasic technique
|| ||
d. CT portography - correct answer✔✔bolus technique
|| || || || || ||
A bolus admin. of contrast agent requires entire vol of material to be injected over the
|| || || || || || || || || || || || || || || ||
shortest possible time. Bolus admin provides the maximum plasma iodine concentration
|| || || || || || || || || || ||
and subsequent tissue enhancement.
|| || ||

|| || || || || || || || || ||
1. tachycardia
||
2. rapid, shallow breathing

a. anticholinergic
||
, b. bronchodilator
||
c. antihistamine
||
d. corticosteroid - correct answer✔✔corticosteroid
|| || || ||
SOLU-CORTEF is a brand name for hydrocortisone. Corticosteroids may be used during tx
|| || || || || || || || || || || || ||
of anaphylactoid reactions to iodinated CM.

|| || || || || || || || || || || || || || ||
answer✔✔dyspnea
What term describes the situation in which an assumption is made that an unconscious or
