The health-care provider prescribed a beta blocker for the client diagnosed with arterial hypertension. Which statement is the scientific rationale for administering this medication?

1. This medication decreases the sympathetic stimulation to the heart, thereby decreasing the client’s heart rate and blood pressure. 2. This medication prevents the calcium from entering the cell, which helps decrease the client’s blood pressure. 3. This medication prevents the release of aldosterone, which decreases absorption of sodium and water, which, in turn, decreases blood pressure. 4. This medication will cause an increased excretion of water from the vascular system, which will decrease the blood pressure.
