I think they will understand just because of COVID, so don’t stress about it! I honestly don’t know when they will start allowing shadowing at hospitals. May not be before the application period is over. But for your sake, you should know if it’s even what you want to do. I’ve had friends that really wanted to be a CRNA, then shadowed one and hated it. Being in ICU, you probably give/get report from OR from them. But what they actually do in OR can be different from what you think. Either way, I wouldn’t stress too much about it. COVID has made everything difficult!
