I feel terrible, I have made a med error in clinical. Somehow, I missed giving a prophylactic heparin injection. I go over my MARs numerous times in a shift and I don't know how I could have missed it. My instructor is wonderful and understanding, she says she has made med errors and I will never forget it and it will make me a better nurse. I am doubting myself so much right now and I fear if I have no confidence it will happen again. I don't want to hurt anyone and I want to do well and be a competent nurse. I could use a little encouragement right now. How did you get over a med error?
