While I agree with some of what you are saying, I do not agree with parts. I have worked in primary care since graduating from LPN (not RN) school 8 years ago. I have done everything from internal medicine to pediatrics to Urgent Care and now work independtly in Public Health. Not all places are like you described. I'm wondering if maybe you are working in a crazy urgent care setting?? Not a primary care clinic??
Anyway, my point is, not all primary care settings are like this and I don't think you should discourage a newer nurse from venturing this way. I chose this line of nursing because it was Monday through Friday 8-5 (working peds I didnt always get off at 5, but pretty close) with weekends and holidays off. This was important to me because I am a single mother. The pay is less than you would get at a hospital or LTC, but you have to weigh the pros and cons. Phone calls are crazy, yes you do have to triage a lot. Med refills, referrals, all that plus doing your patient care, which usually consists of checking the patient in and getting vital signs and a brief history and updating whatever needs to be updated in their charts. Injections are frequent. IV's, not so much. You also have to assist the physician with any procedure he/she may do. In peds we did a lot of in office circumcisions, wart and mole removals, toe nail removals, sutures, things like that.
If you would like a change of pace, go for it. It is definitely different that hospital nursing.
