← Human Body & HealthIf a patient with damage to their preoptic area receives a vasodilator drug during a heatwave, which consequence is most likely?
A)Intense shivering will quickly stabilize
B)Sweat glands activate more aggressively
C)Core temperature will rise uncontrollably✓
D)Peripheral vasoconstriction quickly prevents loss
💡 Explanation
Damage to the preoptic area impairs thermoregulation, specifically the ability to trigger vasodilation and sweating during hyperthermia. Because vasodilation from the drug cannot be modulated, the body will overheat. Therefore, core temperature rises uncontrollably, rather than temperature being regulated by shivering or vasoconstriction.
