The patient is in mild to moderate heart failure but is stable and is seen in the outpatient clinic. The heart rate is slightly elevated at 90. BP is normal at 110/70. The patient receives carvedilol (COREG) to:
A. Suppress the action of acetylcholine at muscarinic receptors thereby decreasing heart rate.
B. Reduce afterload so the heart doesn't have to work so hard.
C. Stimulate alpha-1 receptors and keep the blood pressure up.
D. Activate alpha-2 receptors thereby decreasing SNS outflow from the central nervous system
Which of the following drug classes produces the desired pharmacological effects by interacting with presynaptic receptors to reduce SNS outflow from the CNS?
A. alpha 1 agonists
B. alpha 2 agonists
C. beta 1 agonists
D. beta 2 agonists
If a person has heart failure, the cardiac output is lower than is needed for adequate tissue blood flow. How should you improve cardiac output in a person who has lung congestion, jugular vein distention, tachycardia, and ankle edema?
