I went to a community college that has an LPN and RN program. All LPN and RN students complete the first year together. Then, all students have to decide if they want to exit as an LPN or stay in another 3 semesters to have an RN. Therefore, the first year was as challenging for RN students and LPN students equally. Nursing school is stressful, it causes you to question your abilities sometimes, however, at the same time, you find out things you never new about yourself. I found out who I was in nursing school. I exited as an LPN, I love my job, I may go back to get my RN sometime in the future, but right now, I am right where I want to be.
An LPN works under the guidance of an RN, however where I work, an RN is only at the workplace 40 hours per week. LPNs and RNs do a lot of the same things, however where I live, LPNs can't start IVs (without completing a separate course), and they can't give medication through an IV. Most other things are the same, for example, administering medications, tube feedings, etc. Good luck and congrats on getting accepted into an LPN program!
