Which term describes the four quadrants of the abdomen: RUQ, LUQ, RLQ, LLQ?

• A. Abdominal Regions
• B. Abdominal Quadrants
• C. Epigastric
• D. Umbilical

Answer: (B)

Describing the abdomen in four parts uses the quadrant system. The four sections—upper right, upper left, lower right, and lower left—are created by a vertical line down the midline and a horizontal line through the navel. This setup helps clinicians quickly localize findings or pain to a specific area. The other terms refer to different ways of labeling areas: abdominal regions describe a nine-part division, while epigastric and umbilical point to specific single regions rather than the whole four-quadrant scheme. So the term for the four-part description is abdominal quadrants.
