    Q1. A patient's blood pressure drops after standing. What compensatory mechanism occurs immediately?

    • A) Vasoconstriction of peripheral blood vessels
    • B) Increased urine production
    • C) Decreased heart rate
    • D) Redistribution of intracellular fluids

    Answer: Vasoconstriction of peripheral blood vessels
