Chapter 33: Coronary Artery Disease and Acute Coronary Syndrome Lewis: Medical-Surgical Nursing, 10th Edition

Prinzmetal’s angina is caused by coronary artery spasm. Calcium channel blockers (e.g., diltiazem, amlodipine [Norvasc]) are a first-line therapy for this type of angina. Lipid-lowering drugs help reduce atherosclerosis (i.e., plaque formation), and -adrenergic blockers decrease sympathetic stimulation of the heart (i.e., palpitations). Medications or activities that increase myocardial contractility will increase the incidence of angina by increasing O2demand.DIF:Cognitive Level: Apply (application)REF:713TOP:Nursing Process: ImplementationMSC:NCLEX: Physiological Integrity10.The nurse suspects that the patient with stable angina is experiencing a side effect of the prescribed drug metoprolol (Lopressor) if nt is restless and pressure is 90/54 mm Hnt complains about feeling monitor shows normal sinus rhythm.ANS:B
