Which CV point lies on the midline of the sternum, level with the junction of the first intercostal space?

• A. CV 20
• B. CV 19
• C. CV 21
• D. CV 18

Answer: (A)

The fundamental idea here is mapping the Conception Vessel (Ren) points along the midline of the chest to the intercostal spaces on the sternum. Along this line, each intercostal space corresponds to a Ren point, and the one located at the junction with the sternum’s first intercostal space sits right on the midline at that level.

So, the point that lies on the sternum’s midline at the level of the first intercostal space is the Ren point corresponding to that space. That exact level is what the question describes, making it the best match.

The other options would correspond to adjacent intercostal spaces along the sternum, not the first intercostal space, so they don’t fit the given landmark.
