Nursing and Medical Terminology: A Comprehensive Roadmap for Clear Patient Care in 2024

Medical terminology is the universal language of healthcare professionals. It allows for precise communication, minimizing the risk of misunderstandings and errors.

By understanding medical terms, nurses can accurately interpret medical records, communicate effectively with physicians and other healthcare professionals, and provide clear explanations to patients and their families.

The Building Blocks of Medical Terminology

Before diving into the specific terms, it’s essential to understand the basic structure of medical terminology. Most medical terms are derived from Greek or Latin roots, prefixes, and suffixes. By understanding these building blocks, you can decipher the meanings of unfamiliar terms and enhance your overall comprehension.


Roots are the core components of medical terms, representing the basic meaning or subject matter. For example, the root “cardi” refers to the heart, while “neur” relates to the nervous system.


Prefixes are word elements placed before the root to modify or specify its meaning. For example, the prefix “hyper” means excessive or above normal, while “hypo” signifies below normal or deficient.


Suffixes are word elements added to the end of a root to indicate a specific procedure, condition, or disease. For example, the suffix “-ectomy” refers to the surgical removal of a body part, while “-itis” indicates inflammation.
