NUR240 Quiz: Chapter 28 Drug Chart
Document Summary
Angina (while acute angina episode is in progress) Formation of nitric acid which is a potent vasodilator; dilates veins to reduce preload. Selectively blocks beta1 adrenergic receptors in the heart (slows hr and reduces contractility) Do not give with ed medications (viagra); can cause severe hypotension. If angina worsens during withdrawal period, drug should be reinstituted. Od: use atropine or isoproterenol to reverse bradycardia. Patients with hypotension, head trauma/increased intracranial pressure, glaucoma, cardiac tamponade, constrictive pericarditis. Black box: abrupt discontinuation should be avoided in those with ischemic heart disease. Severe bradycardia, av heart block, cardiogenic shock, decompensated hf. Chapter 28: drugs for angina pectoris and myocardial infarction. Inhibits transport of calcium into myocardial cells (relaxes both coronary and peripheral blood vessels, bringing more oxygen to myocardium) Cleaving plasminogen to form plasmin; plasmin then degrades the fibrin matrix of thrombi. Abrupt withdrawal may precipitate an acute anginal episode. Patients with av heart block and severe hypotension.
