Explain why repeated transfusion of Rh-positive blood to a Rh-negative recipient can cause severe shock to the recipient.

When a large number of stuck together red blood cells move in the blood, they can lead to blockage of the lumen of the vessel and its subsequent rupture. In fact, 85% of Europeans are Rh positive.
