A patient comes in for a physical examination and complains that she was "freezing to death" while waiting for her examination. The nurse notes that her skin is pale and cool, and attributes this finding to:
peripheral vasoconstriction
peripheral vasodilation
venous pooling
decreased arterial perfusion
The Correct Answer is A
A. Peripheral vasoconstriction:
In response to cold, the body constricts peripheral vessels to preserve core temperature, leading to pale, cool skin.
B. Peripheral vasodilation:
Causes warm, flushed skin, not pale and cool.
C. Venous pooling:
Would lead to reddish-blue discoloration and possibly swelling-not pallor and coolness.
D. Decreased arterial perfusion:
Could cause pale and cool skin chronically, but in this case, it's an acute environmental response, not pathological.
