I am at the end of my first semester of nursing school and clinicals were great for me. It helps you apply the things you learn in your basic nursing class. Like you I was so nervous my first day, but it gets better! We started out by giving baths and taking vital signs and by the end of the semester we were doing glucometers, giving meds, and doing physical assessments on our assigned patients and charting. Each group had 10 students to one instructor and you can always depend on each other for help or advice. It will be a great experience and you will be fine! Good luck!
