O.K., Here it goes!
RN (Registered Nurse),
ADN (Associate Degree Nurse),
BSN (Bachelors of Science in Nursing),
MSN (Masters of Science in Nursing),
NP (Nurse Practitioner),
PA (Physicians Assistant),
LVN (Licensed Vocational Nurse),
LPN (Licensed Practical Nurse),
CNA (Certified Nursing Assistant),
NA (Nursing Assistant),
PCA (Patient Care Assistant),
MA (Medical Assistant),
OT (Occupational Therapist),
PT (Physical Therapist),
RD (Registered Dietician).
Then you have various certifications, like CRN (Certified Registered Nurse in a speciality area), BLS (Basic Life Support), ACLS (Advanced Cardiac Life Support), PALS (Pediatric Advanced Life Support), NALS (Neonatal Advanced Life Support) and this list goes on and may even vary depending on what part of the country you live in.
Then, you have medical abbreviations
like PRN, which is latin for "pro re nata", meaning as needed. Every hospital that you work at should have a list of acceptable standard abbreviations for that facility. PD means per diem, which is a hiring status that excludes benefits. I hope this helps you and if anyone else would like to elaborate on this list that would be great. There are abbreviations and initials that I haven't a clue what they stand for. It's all so confusing, isn't it!
