Which acupuncture point corresponds to the description: in the fourth intercostal space, 2 cun lateral to the midline?

• A. KD 22
• B. KD 24
• C. KD 25
• D. KD 23

Answer: (D)

This item tests precise point location on the chest along the Kidney meridian using the intercostal space and distance from the midline. The description places the point in the fourth intercostal space, 2 cun lateral to the midline. That exact combination corresponds to Kidney 23. In standard charts, Kidney 23 is located in the fourth intercostal space, two cun to the side of the midline, on the chest along the Kidney meridian. So the described location matches Kidney 23. The other options sit in different spaces or at different lateral distances, so they don’t fit this description.
