Q. Which best explains how vitamin D toxicity causes stupor and coma.
a
It activates osteoblast release of RANKL, which promotes maturation of osteoclasts and the breakdown of bone, which releases calcium, and thus the hypercalcemia produces the stupor and coma.
b
It activates PTH breakdown of bone, which releases calcium, and thus the hypercalcemia produces the stupor and coma.
c
It is a direct activator of osteoclast maturation; they are responsible for the breakdown of bone, which releases calcium, and thus hypercalcemia produces the stupor and coma.
d
It activates osteoblast release of RANKL, which inhibits maturation of osteoclasts and the breakdown of bone, which causes hypocalcemia produces the stupor and coma.
