KD-16 is located on the upper abdomen, 2 cun above the umbilicus, 0.5 cun lateral to the midline.

• A. REN-10
• B. REN-11
• C. KD-18
• D. KD-16

Answer: (D)

This question checks precise abdominal point location using cun measurements and the midline. KD-16 is defined as being in the upper abdomen, 2 cun above the umbilicus and 0.5 cun lateral to the midline. The key detail is the slight off-midline position, which places the point on the Kidney meridian in that region. Points on the Ren (conception vessel) channel lie on the midline, so a description that specifies a lateral offset points away from Ren and toward the KD channel. Therefore, the described location matches KD-16.
