A nurse is caring for a client with atrial fibrillation who is taking metoprolol (Lopressor) 50 mg BID (twice daily). Which is the correct description of the mechanism of action of this medication? Allows the blood vessels to relax and dilate and increase blood flow through the coronaries. Reduces blood pressure by inhibiting the renin-angiotensin-aldosterone system (RAAS) to decrease work load and oxygen demand. Dilates coronary arteries when converted to nitric oxide. Inhibits the sympathetic nervous system’s response to physical activity, decreasing work load and oxygen consumption.
