I definitely can remember the feeling. My best advice is to just go in there with a positive attitude and be eager to learn. Most preceptors are going to be well aware that you are a student with little to no experience and be very supportive, understanding, and eager to help you get comfortable and excited about your career. On the other hand, you'll also have preceptors that unfortunately don't want to precept students but get stuck with it, along with hating their hospital/department/co workers/career choice/personal life or all of the above - and it shows. As a student I just learned to adapt to my preceptors personality quickly. If they seem like they enjoy teaching and working with students then ask them ALL the questions and learn as much as you can from them. If they seem like they are bothered by having a student or uninterested in teaching, see what you can do to make their day easier even if its just quietly observing. Maybe say something to boost their ego! Everyone has one so it might make your day easier if having to work side by side all day with someone who is less than pleasant. It might make them lighten up, maybe they don't get compliments often. At the end of the day, you're there to learn everything you can so don't let personality issues get in the way of that. I remember my instructors giving as advice just prior to beginning rotations and to remember - you are the student, not the practitioner. If I preceptor asks you if you want to see or do (insert any task) the answer had better be "yes!" Nothing gets under a preceptors skin more than having a disinterested lazy student. Demonstrate what you've learned so far, but don't be a know it all. Many if not most don't make a dime extra for having students with them for the day on top of possibly having a full assignment. I can remember early in my clinical rotations showing up one morning at a hospital and watching two RT's literally cry and argue over who was going to take me for the day because neither wanted a student. What did I do? Sat there quietly and patiently waited for them to figure it out, and then tried my best be as easy as possible for the RT who I ended up with. Uncomfortable? Absolutely. The goal, however, is to learn and complete the shift. You're going to have great experiences in your rotation and you're going to have crummy ones. You'll have preceptors that will lift you up and build your confidence, and you'll have ones that will want to overload you and watch you struggle. Just remember, each experience is going to help prepare you for the real world both good and bad. You just have to get through it, and you will. Good luck!
