← Human Body & HealthWhy does a patient with advanced cirrhosis often experience decreased blood pressure despite increased cardiac output?
A)Increased renin-angiotensin system activity
B)Enhanced sympathetic nervous system activation
C)Elevated levels of vasoconstricting hormones
D)Increased nitric oxide-mediated vasodilation✓
💡 Explanation
In advanced cirrhosis, increased nitric oxide production leads to systemic vasodilation, which lowers blood pressure, because the vasodilation effect overrides the increase in cardiac output. Therefore, the vasodilation from nitric oxide is the primary driver, rather than vasoconstriction or the renin-angiotensin system.
