2. Releases aldosterone
3. Decreases cardiac output
4. Decreases heart rate
5. Causes arteriolar vasodilation
1,2
Rationale 1: Activation of the renin-angiotensin-aldosterone system increases vasoconstriction through the release of angiotensin II, a potent vasoconstrictor.
Rationale 2: Activation of the renin-angiotensin-aldosterone system increases water and sodium reabsorption through the release of aldosterone.
Rationale 3: Activation of the renin-angiotensin-aldosterone system does not decrease cardiac output.
Rationale 4: Activation of the renin-angiotensin-aldosterone system does not decrease heart rate.
Rationale 5: Activation of the renin-angiotensin-aldosterone system does not cause arteriolar vasodilation.
