A 75-year-old male patient was admitted to the unit with angina. He was started on nadolol (Corgard). The patient asks why he is taking this medication because he does not have high blood pressure. What is the nurse's best response?
A) "Some beta-blockers have been approved as antianginal agents."
B) "This medication will prevent blood pressure problems later on."
C) "This drug will prevent you from developing an arrhythmia."
D) "This medication will reduce benign prostatic hypertrophy (BPH) as well as treat heart failure."
A
Feedback:
Decreased heart rate, contractility, and excitability, as well as a membrane-stabilizing effect, lead to a decrease in arrhythmias, a decreased cardiac workload, and decreased oxygen consumption. The juxtaglomerular cells are not stimulated to release renin, which further decreases the blood pressure. These effects are useful in treating hypertension and chronic angina and can help to prevent reinfarction after a myocardial infarction by decreasing cardiac workload and oxygen consumption. Corgard will not prevent blood pressure problems, arrhythmias, or glaucoma in the future. Corgard is not used to treat BPH.
