@gailcalled pretty much summed it up with that link. What a LPN does on a daily basis will vary depending on where they work. There are some pretty big differences between what is done in a doctor’s office and in a hospital.
In the hospital setting, LPNs provide much of the daily care to the patient (sometimes on their own and sometimes while working with a nursing assistant, depending on the hospital). They will perform assessments, vital signs, administer medications, and assist with activities of daily living (such as personal hygiene and exercises). A lot of what they will do will depend on the doctor’s orders and the hospital policies. Some states allow LPNs to give IV medications after receiving additional training, but some don’t. Some states also use the term Licensed Vocational Nurse instead of Licensed Practical Nurse.
In a doctor’s office, it will depend on the set up of the office. In the office I work at right now, we have medical assistants that usually check in the patients, but the nurses help out when the MAs get busy. The nurses primarily assist the doctors during the visit when necessary, do phone triage, do referrals to other places, and refill prescriptions. Sometimes the nurses will have to give injections, but some states allow MAs to do injections if the doctor will cover them under their insurance.
From my experience, the hospital setting is a lot more hands on than a doctors office is.
