CPB (Certified Professional Biller) Certification Practice Exam

Which prefix denotes "in, into, not"?

1. A. Ileum (small intestine)

2. B. In, into, not

3. C. Uterus, womb

4. D. Within, into

The correct answer is: B. In, into, not

The prefix that denotes "in, into, not" is accurately identified as the one provided in the choice. This prefix is crucial in medical terminology as it helps convey different meanings or modifications to the root word it is attached to. For instance, "in-" or "im-" can signify negation, like in "inaudible," meaning not audible, or indicate direction, as in "inject," meaning to place into. The other options involve either specific anatomical terms or do not function as prefixes in this context. The option referring to the ileum focuses on a specific part of the digestive system, while the mention of the uterus pertains to reproductive terminology. The last option uses terms that describe location but does not hone in on the prefix aspect as clearly as the correct choice.
