I just had surgery and the nurses were all dressed alike. Yep. BUT the cool thing was that they each had a carry tote for needles, syringes, etc. The totes weren't huge, but held a lot. They were what looked like laminated fabric and I asked if someone made them. Nope. Hobby Lobby! So they each knew "their" tote by the colors on the fabrics and it held everything they needed. So the tool belt or tote for on the job might be a good idea. I think the totes were originally for crafters, but hey, why not use it for nursing items?
