Which CV point is on the midline of the sternum, level with the junction of the third intercostal space and the sternum?

• A. CV 17
• B. CV 19
• C. CV 18
• D. CV 20

Answer: (C)

The location being tested is the exact spot along the anterior midline where a Conception Vessel point sits at the level of the third intercostal space on the sternum. Along this midline, these chest points are mapped to specific intercostal spaces: the one at the 4th intercostal space is at CV17, the one at the 3rd intercostal space is CV18, the 2nd intercostal space is CV19, and the 1st intercostal space is CV20. Since the description specifies the midline of the sternum at the junction with the third intercostal space, the correct point is CV18.
