单项选择题
During a shock state, the renin-angiotensin-aldosterone system exerts which effect on renal function
A．Decreased urine output, increased reabsorption of sodium and water.
B．Decreased urine output, decreased reabsorption of sodium and water.
C．Increased urine output, increased reabsorption of sodium and water.
D．Increased urine output, decreased reabsorption of sodium and water.
答案
参考答案：A
解析：As a response to shock, the renin-angiotensin-aldosterone system alters renal function by decreasing urine output and increasing reabsorption of sodium and water. Reduced renal perfusion stimulates the renin-angiotensin-aldosterone system in an effort to conserve circulating volume.
