Common Disease Suffixes
As Certified Nursing Assistants (CNAs), it’s crucial to have a basic understanding of medical terminology. This understanding allows for effective communication with the rest of the healthcare team and enables CNAs to provide quality care to their patients. A fundamental aspect of medical terminology is recognizing disease suffixes. These are ending parts of words that often indicate the type, symptoms, or location of a disease. This blog post will discuss some of the most common disease suffixes that CNAs are likely to encounter in their practice.
What is a Suffix?
Let’s start by first defining what a suffix is. In language, a suffix is a letter, syllable, or group of syllables added at the end of a word or word root to change its meaning, give it grammatical function, or form a new word altogether. Suffixes are one of the three primary types of affixes—the other two being prefixes, which are added at the beginning of a word, and infixes, which are inserted into a word.
When it comes to medical terminology, suffixes play a crucial role. They can indicate a procedure, a condition, a disease, or a part of speech. The wonderful thing about understanding medical suffixes is that even if you come across a term you have never seen before, you can piece together its basic meaning by understanding the prefix, root word, and suffix.
In this context, a disease suffix, as we’ve been discussing in this blog, refers to the ending part of a medical term that describes certain characteristics of diseases. This could mean the location of the disease, the nature of the disease, the intensity, the cause, or the symptoms associated with the disease.
Mastering medical suffixes is a key part of being a proficient healthcare professional, as it allows for effective communication and understanding in the clinical environment.
Using Suffixes in the Clinical Environment
As CNAs, understanding the disease process is important, but it’s equally critical to apply this knowledge in the clinical environment. With your newfound understanding of disease suffixes, you can:
Improve Communication: Knowing these suffixes will enhance your communication with doctors, nurses, and other healthcare professionals. You’ll be better able to understand the information they share about patients’ conditions and care requirements, and you can also more effectively share your observations.
Enhance Patient Education: In your role as a CNA, patients often look to you for information and guidance. Understanding these suffixes will allow you to explain medical terms, conditions, or procedures to patients and their families in a way they can understand, reducing their anxiety and improving their cooperation with the care plan.
Better Documentation: Medical documentation often includes complex terms that incorporate these suffixes. Your understanding of these terms will make you better at reading and contributing to this documentation, ensuring accurate and efficient communication and record-keeping.
