Step-by-step explanation:
The question is asking if the person's arm has become cold, pale, or blue. This question is trying to rule out the possibility of impaired circulation to the arm caused by vasoconstriction or reduced blood flow.
When the body experiences injury or stress, the blood vessels near the injured area can constrict or narrow to minimize bleeding and protect the body. This vasoconstriction can reduce blood flow to the affected area, leading to symptoms such as coldness, paleness, and blueness. By asking if the arm has become cold, pale, or blue, healthcare professionals can gather information about the extent of the injury and its impact on blood circulation.
