This is typical in dialysis training for RNs. I have 5 yrs exp as a tech and 3 yrs as RN in HD. Most of your techs are far superior at machine trouble shooting and difficult cannulations (sticks) as RNs are geared more towards assessments, medications, and orders. Learn as many tips as you can from your tech trainer, soon you'll be with your RN trainer. I worked for the 2 largerst companies (Davita & Fresenuis), and staff shortages are ongoing due to low pay, poor wage increases, and bad ratios. So plan on working as a tech when tech numbers are low, and learn their duties: machine start up, clean cycles, reuse, patient packs, machine set packs. I have recently escape HD for a hospital urgent care setting. Outpatient nursing with hospital pay; the best of both worlds. Good Luck in HD.
