Patients with impaired ____________ must be adequately assessed before an iodinated contrast is administered because these patients are at risk for increased disease.
renal or liver function
Normal Creatinine:
0.7-1.3 mg/dL

As a technologist if you inject contrast media and see extravasation by looking at the:
hematoma under the skin
How do you manage an extravasation?
remove the needle, apply warm compress and elevating the effecting extremity. Immediate attention is needed to prevent tissue necrosis if the extravasation involves a corrosive drug and a cold compress should be applied at the site.
Accidental infiltration of a vesicant- (contrast media) into the interstitial tissues at the site of injection. Pain swelling, redness.
Extravasation
When fluid infuses the tissue surrounding the venipuncture site.
