List of Medical and Nursing Abbreviations, Acronyms, Terms 1


What does HOB or ROM means? Do you know the different medical and nursing terms from the healthcare industry? We in the fields of nursing and medicine have our unique set of vocabulary. These terminologies are important for us to have a more understandable and efficient communication. [no_toc]

Differentiating abbreviations from acronyms

  • Abbreviations are shortened forms for written words or phrase used in a place of the whole (e.g., vol for volume).
  • Acronyms are words formed from the initial letter of each of the successive parts or major parts of a compound term (e.g., CBC for complete blood count).

Matt Vera is a registered nurse with a bachelor of science in nursing since 2009 and is currently working as a full-time writer and editor for Nurseslabs. During his time as a student, he knows how frustrating it is to cram on difficult nursing topics and finding help online is near to impossible. His situation drove his passion for helping student nurses through the creation of content and lectures that is easy to digest. Knowing how valuable nurses are in delivering quality healthcare but limited in number, he wants to educate and inspire students in nursing. As a nurse educator since 2010, his goal in Nurseslabs is to simplify the learning process, breakdown complicated topics, help motivate learners, and look for unique ways of assisting students in mastering core nursing concepts effectively.
