HOSA Medical Terminology – Prefixes and Suffixes Practice Test

The suffix "-pnea" is derived from the Greek word "pnoia," meaning breathing. It is commonly used in medical terminology to refer to various conditions or states related to breathing.

Looking at the terms provided:

- "Dyspnea" refers to difficult or labored breathing, with "dys-" indicating difficulty. It clearly includes the suffix "-pnea."

- "Apnea" refers to a temporary cessation of breathing. The prefix "a-" indicates a lack of something, in this case, a lack of breathing, and it also incorporates the suffix "-pnea."

- "Pneumonia," while it may seem related due to its root "pneumo-" referring to the lungs, does not accurately contain the suffix "-pnea." Instead, it pertains to an infection in the lungs.

Thus, the terms that correctly include the suffix "-pnea" are "Dyspnea" and "Apnea." The choice suggesting that all terms include this suffix is incorrect because "Pneumonia" does not fit the criteria. Therefore, the correct answer focuses solely on those terms that incorporate "-pnea," particularly highlighting the meanings related to the act or condition of breathing.
