patients receiving dialysis?

contrast media; patients with end-stage renal failure can be given contrast media.
c. When contrast media is given, dialysis must be scheduled to be performed within 4
hours.

d - answerIn what circumstances is it acceptable to use a large-bore tunneled dialysis
catheter for the injection of iodinated contrast media?
a. Whenever a standard peripheral IV access is not available
b. When the contrast flow rate is 2 mL/s or less
c. When the patency of the line has been verified by flushing with saline
d. A dialysis catheter should never be used for contrast media administration
d - answerDocumentation of IV contrast administration is
a. only necessary when an adverse event occurs
b. only necessary when routine injection parameters are modified
c. required on all patients and must be cosigned by a radiology
d. required on all patients and should include the name of the agent, the dose, the flow

patient throughput can be increased
b. improve patient safety by reducing contrast extravasations
c. effectively accommodate for individual differences in circulation time by adjusting the
scan delay

contrast flow rate

d. Ionic nature
b - answerIn performing CT colonography, which is an advantage of CO2 over room
air?
