A patient comments, "I don't understand why I have chest pain at times when I'm resting or exercising. How will metoprolol (Toprol XL) help?" Which of the following comments made by the nurse is correct?
a. "It improves sympathetic stimulation to the heart."
b. "You've probably had several minor heart attacks, therefore SL nitroglycerin would be more appropriate."
c. "It improves the right ventricular ejection fraction."
d. "It increases exercise tolerance"
D
When administered on a fixed schedule, beta blockers can provide sustained protection against effort-induced anginal pain. Exercise tolerance is increased, and the frequency and intensity of anginal attacks are reduced, thus reducing stress on the heart.
Beta blockers reduce oxygen demand and block sympathetic stimulation.
Nothing indicates that this patient has suffered a heart attack, therefore a statement referring to a heart attack would be a poor choice.
Beta blockers may in fact reduce the ejection fraction, as well as AV conduction and contractili-ty.
