Hi. I am in the first semester of nursing school. I have run into some things I don't know the meaning of when filling out my data base. What doe "nos" mean at the end of something, such as anemia "nos"? And "nec" for that matter? Also unfamiliar with the abbreviation ASCVD? One more and I swear I'm finished, "malign neople breast nos"? This may sound incredibly stupid on my part, but I honestly don't have a clue. Thanks so much for any help you can give me on the matter.
