My clinical preceptor at a local ED was an ER Tech, who was a paramedic prior to landing the spot at the ED. She told me her training as a paramedic gave her plenty of prehospital experience that supplemented her clinical career. Also, as a paramedic, she had a bigger scope of practice compared to other ER Techs (who were mostly EMT-Bs). The RNs let her do IVs, etc because of her expanded scope of practice.
