Hello all, so here's my story: I have worked in Public health a few years, I do quite a bit from case management, med administration ( Antibiotics, pain med, etc), MAT treatment for substance misuse,EKGs, triage, setting up appointments, wound care, nursing visits, etc. I want to keep on learning, I do have a desire to work in a hospital but the pay is good where I'm at ($48 per hour, 40hr week), good benefits,good coworkers and work balance. What Certificates would you recommend, books to read, or other resources to stay up to date? I'm currently reading ER book for MDs, comprehensive lab book, and wound care book, looked into PESI certifications but kinda look shady. Thank you for any suggestions.
