Whoo, tummy is doing flip flops right now. I don't even want to talk about this because it's a huge point of personal shame for me, but I have to offer my perspective.
I've been on the preceptee side of a similar situation. Granted, I was my preceptor's first student. Plus, whereas I was a B student in an associate degree program, she was the valedictorian of her BSN cohort and had already taken part in a published study; basically this girl's expectations were bound to be dashed. The whole thing was a big shitty self-fulfilling prophecy.
I tried to be hyper-communicative and asked tons of questions, I made a point to take initiative and get things started without needing to be asked, I worked 12-hour night shifts with only a 15 minute break in order to get all my work done. Still, I was up against a huge learning curve, I had no hospital experience (day shift skilled nursing/rehab CNA), and I needed a lot of hand-holding. Mistakes? I made a few, but I learned from my mistakes, talked to her about them, and I thought I was doing well until I got her mid-term review. Not satisfactory. I met with my instructor, made a plan for improvement, worked even harder. In the end, I barely passed. Up until that last quarter, all my clinical experiences had been great. I'd been commended for my effort and efficiency multiple times.
After many a cry session (poor me!), I've come to the conclusion that the problem was (as it always is) communication. When I asked my preceptor for feedback about my performance, her suggestions were too vague to be beneficial. To throw oil on the fire, she and my instructor had little contact, and in fact the only time my instructor came to the floor to check up on my progress was the day after the mid-term review. Fuck me, right?
Point being, just make sure this guy knows how disappointed you are in his performance. Be specific about what he needs to do to improve. Lead by example. One thing that really helped me near the end of my preceptorship (too little, too late, but it still helped) was to ask for immediate feedback right after leaving the patient's room. Go over what went right and what didn't. Explain how you would have done it. Give this guy homework. Force him to show motivation (my instructor had me create a concept mapkillmenow for a patient in order to illustrate my thinking process and prove I wasn't a complete nincompoop. Never did get any feedback on that concept mappleaseneveragain).
In summation, please give this guy the benefit of the doubt. Make sure your expectations are clearly laid out, and make even more sure that he knows he's currently not meeting them.
I definitely don't think you're eating your young in this situation. You've already proven yourself a good NurseMama. This guy is obviously not competent as a nurse. But maybe he might be, someday. Maybe. Anywhosen, I felt compelled to blurt out my story just in case this guy has a good nurse hidden underneath what sounds like a pretty douchey exterior.
the more you know...
TL;DR: I've been a shitty student nurse before, but I was really trying, so make sure this guy knows you're disappointed before taking drastic action!
inb4: Yes I'm planning on getting my BSN. Currently studying for NCLEX, looking to get RN experience at my current skilled nursing/rehab facility (they LOVE me over there) before applying to a bridge program. Figured I wouldn't get into an RN-BSN program without a recommendation from the preceptor so why bother.
Congratulations if you're still reading this, and sorry for my long-winded nature.
