Welcome to the forum.
As a health care worker, you need to read up on HIV transmission risks and perhaps speak with your employer. Nobody in the world has ever acquired HIV from the sort of events you describe, and nobody ever will.
Standard lists of HIV risks always include blood exposure. But the only blood exposures ever known to have transmitted the virus were direct injury with sharp instruments visibly contaminated with infected blood, blood transfusion, shared injection equipment, and the like. HIV dies on drying or air exposure, so even if HIV contaminated blood or secretions had been left on a doorknob, handling that knob -- even with a fresh cut -- carries no risk whatoever.
So as you say yourself, your concern her is certainly far-fetched -- and although not quite "irrational", it's pretty close. You could not have been infected and do not need testing for HIV.
