The Renin-Angiotensin-Aldosterone System Compensates for Hypovolemic Shock by Stimulating

question 43

Multiple Choice

The renin-angiotensin-aldosterone system compensates for hypovolemic shock by stimulating:

• A)antidiuretic hormone from the posterior pituitary to retain potassium and excrete sodium to improve myocardial contractility.
• B)ß1-adrenergic receptors to increase myocardial contractility, heart rate, and conduction through the atrioventricular node.
• C)aldosterone release, which retains sodium and hence water to increase the blood volume.
• D)movement of calcium into vascular smooth muscle, causing vasoconstriction and increasing systemic vascular resistance.
