I graduated from nursing school at 55 and now I am in my 60's. People think I have been a nurse for at least 35 - 40 years but I am still learning all the time! Yes, I make mistakes and encounter the Spanish Inquisition at report time from nasty RN's the age of my grandchildren. Nursing is tough and not what I expected. But we all make mistakes and you are on the right track establishing an organized plan of care. I live with a drug book, my own special report sheet for each patient with medication/treatment times listed (like you do), and readjust when things change. Often I am tired and blame it on my age. But I am not ready to sit home and watch the soaps and Oprah either. I plan to keep on going until 70 if I can. By then I may be a charge RN!!! Please don't give up. Nursing needs you and bedside nursing is wonderful. Good luck!
