← Human Body & HealthWhich risk increases when arterioles in hypertensive crisis undergo vasoconstriction?
A)Reduced systemic oxygen delivery✓
B)Increased glomerular filtration rate
C)Decreased cardiac preload reserve
D)Reduced cerebral spinal fluid pressure
💡 Explanation
Reduced systemic oxygen delivery increases because increased arteriolar resistance from vasoconstriction overwhelms oxygen supply through reduced capillary perfusion; therefore cellular hypoxia risks increase rather than increasing filtration because autoregulation fails in extreme pressure increasing tissue damage.
