A) "The white patches are caused by a deficiency of vitamin D."

C) "The white patches occur when there is a low carotene level."

B
Feedback:
The nurse should inform the client that the white patches on his skin are a result of vitiligo. Vitiligo is caused when melanocytes stop making melanin, which causes distinct localized areas of white. Carotene is a yellowish pigment found in parts of the epidermis and the dermis. Carotene is the precursor to vitamin A. A low level of carotene does not cause vitiligo. A deficiency of vitamin D and lack of calcitriol are not known to cause vitiligo.
