When this patient complains that his hands become pale, blue and painful when exposed to cold, the disease that the nurse should cite in as an explanation for these signs and symptoms is Raynaud's disease.

The blood vessels narrows and limiting the blood circulation to the affected areas. This effect is called vasospam.
