My very first clinical of nursing school, I had a terrible instructor. He was knowledgable, but had very poor communication skills, poor time management, and overall was just an intimidating person who became furious at students when they asked questions.My first story about him was I was testing a patient's blood sugar. I opened the cap to the test strip container, and I set the container down on the counter. I inserted the test strip into the accu-check meter, and then I proceeded to close the cap to the test strip container. The instructor was enraged and explained that I let air get into the test strip container too long, and I ruined the rest of the test strips in the container. He threw the rest of the test strips away (what the heck???). Secondly, I missed a day of clinical in the middle of the semester due to a bad case of the norovirus (throwing up every 15 minutes - yikes!). When I returned the next week, it was only the second time I ever passed medications. I had a question about the order in which I was supposed to scan the medications in the computer. He gave me this horrified blank stare and said "You have forgotten everything, and this could be very dangerous to the patient". This was at the patient's bedside and it began to make the patient very uncomfortable and anxious that something was wrong. The instructor and I had already previously prepared the medications, and ensured we had the right drug, right dose, right patient, etc. Later in the day in post-conference the instructor kept mentioning to the rest of my fellow classmates that "[wsunurse14] had forgotten everything" several times. I could go on forever about this instructor, but I won't. What I really want to know is what are your clinical instructor horror stories?
