I am an RN, but I will try to offer some insight, based on discussion with some of the LPNs on my unit.
Many LPN programs are offered through technical schools. The program can be as long as 2 years, depending on how many of the required prerequisites your daughter has(mostly science courses). She would probably do best to check that out with whatever schools she interested in attending. LPNs have to take a state certification exam(as do RNs). LPNs have slightly less responsibilty in most cases, and work under the guidance of an RN. In my hospital, LPNs cannot be in charge, there are certain medications they cannot administer, there are certain nursing procedures they cannot perform. Their pay is not as high as that of an RN.
There are many schools now that offer 2 year RN/Associates degrees...the college of nursing affiliated with my hospital does that. My recommendation to your daughter would be that if it is going to take her 2 years to be an LPN and 2 years to be an RN, then she should go for the RN. There has been some talk in nursing circles in recent years that the LPN role will be dramatically reduced in the next few years, almost to the point of having an LPN act as a nurses aide. One hospital in my area has, in fact, already demoted all of their LPNs to nurses aide level.
Remind your daughter that there are several fields in the health/human services area that could be of interest other than nursing, such as pharmacy tech, medical assistant, lab tech, radiology tech, phlebotomist,nuclear med tech, ultrasonographer, medical coder(a great job that can often be done from home!).
If she is needing a change from her current situation, nursing may not be the asnwer, because it sounds as if many of the "situations" she currently encounters, she will encounter as a nurse. We deal with difficult patients all the time, We get physically attacked by patients and families on a fairly regular basis, the hours are long and lousy, the pay is adequate for the hours worked, but very inadequate when you actually think of the level of responsibilty and lack of respect there is for the profession
My recommendation for her, if she is looking for something that will give her the satisfaction of person-to-person contact without as much of the inherent danger is to look into radiology tech,phlebotomy,ultrasonography or something more along those lines.
