2. Toward; near

3. Through

4. Before

The correct answer is: Toward; near

The prefix "Ad-" derives from Latin and is used in medical terminology and other fields to signify a meaning of direction or spatial relationship. Specifically, it indicates a position of moving toward something or being near to a particular location. This interpretation aligns with the concept of proximity or directionality in anatomical, clinical, or contextual references. For example, in medical terms, "adduction" refers to the movement of a limb or body part toward the midline of the body, illustrating how this prefix conveys a sense of approach or closeness. Understanding this prefix is crucial for interpreting many terms in medical coding, as it helps specify anatomical locations and movements which are essential for accurate documentation and coding practices.
