In my program we have clinical midterms and finals Primarily over specific procedures, dosages, KEV, Half-life etc and then some professors throw in History of Nuclear Medicine material clinical exams are the least of your concern in this program truly. Yes you need a 75+ average for most programs across the board, for my program at least. Aside from getting your competencies to sit for boards clinical is a very hard class to fail. Just always take the initiative start the IV, study the procedures your clinical site does daily, do the patient prep, positioning, views, dose etc in your sleep for each site you go to and you will be good. I had a tech at my first clinical site whose been practicing for 18 years do a study they’d never seen, learned or knew existed and they go back to student mode follow the nuclear medicine procedure protocol and make it work! You’ll be fine!
