Hi nograd. I can TRY to answer you, and I say try because the Radiology Nurse's duties vary from facility to facility. Mainly, we take care of the patients!
We sedate (mild to moderate) and monitor pts for diagnostic and interventional procedures (angiograms, TIPS procedures, biopsies, placement of drains in abscesses, placement of percutaneous nephrostomy tubes, placement of tunneled dialysis catheters, interventional radiology procedures: thrombolysis of AV grafts/fistulae, embolization of AVMs (arteriovenous malformations), chemoembolizations of hepatomas, vertebroplasties, . . .), "working up" the patient beforehand (making sure there are no surprises before or during the procedure, e.g., checking that the patient to receive an angiogram has normal BUN and creatinine, platelets and a fairly normal CBC, as well as NOT being allergic to the iodine contrast, and also making sure that if the patient is diabetic and taking metformin, the patient has withheld the dose for the appropriate time before and after the angio), doing patient teaching about the procedure and post teaching afterwords; Setting up for the procedure and circulating during it (gotta know the pattern of how the procedure should go, anticipate the Radiologist's needs with supplies). Some nurses start all the out-pt IVs for CT scans (we had two scanners and doing one exam every 20-30 min, could start as many as 20-40 IVs per day, not to mention the nurse monitors each patient receiving the contrast for allergic reactions: recognize, treat quickly, do pt. teaching post), which may include doing post-exam teaching for hydration and watching for delayed s/sx of allergic reaction. Some do post-procedure recovery in a special area. Usually, though, in the dept, nurse-to-patient ratio is 1:1.
Some Radiology nurses assist with Persantine-Thallium Stress Tests in Nuclear Medicine. Some sedate or provide oral meds for anxiolysis for claustrophobic pts who need an MRI.
You use a lot of assessment skills, critical thinking, COMMUNICATION SKILLS, and what I like to think of as creative thinking skills
As I said at the beginning, the duties vary from place to place. Some institutions may have things set up so the nurse helps with a narrower range of procedures, but does more follow-up and case management-type duties.
Hope this helps. You may PM me if you have any more questions, I'll be around this weekend and usually check in at least twice a day. Good luck! -- D
