++
++
++
++
++

When a woman who has been on a low-sodium diet for 8 days is given an intravenous injection of captopril, a drug that inhibits angiotensin-converting enzyme, which of the following would be expected?
++
++
++
A. Blood pressure to rise because cardiac output would fall
++
++
B. Blood pressure to rise because peripheral resistance would fall
++
++
C. Blood pressure to fall because cardiac output would fall
++
++
D. Blood pressure to fall because peripheral resistance would fall
++
++
E. Plasma renin activity to fall because circulating angiotensin I level would rise
++
++
++
Which of the following would not be expected to increase renin secretion?
++
++
++
A. Administration of a drug that blocks angiotensin-converting enzyme
++
++
B. Administration of a drug that blocks AT1 receptors
