I am 2+ years with long covid-after becoming infected working as an ER RN with covid patients, before vaccines were FDA approved. I am not able to return to nursing in any capacity. Simulating CPR caused profound shortness of breath and a heart rate in the 130's. I tried lifting 35 pounds with the same result. Cognitively, I am certain I would be unsafe with medications. In short, I would not want me for a nurse, let alone for my family. I tried to simulate what a shift would be like to test myself. Add up the time you need to get ready for work, leave the house, travel to work, bending, lifting walking at a brisk pace, complicated abstract thinking in a noisy environment with constant interruptions. After all of that, manage getting home, preparing a meal, managing your finances. I tried 4hr. vaccine clinic shifts, 3 times a week to start with-I lasted 5 spread out shits. I forgot to ask about allergies before giving an injection. I 'crashed' after the first day.
Best of luck to you-I hope you make it! Nursing was a huge piece of me that I have lost.
