Step-by-step explanation:
Nadolol, a beta-blocker, is prescribed for a client with chronic stable angina. The nurse should monitor for the ability to do daily activities without chest pain as an indication that the drug is effective. Chronic stable angina is angina that is precipitated by exertion and improves quickly with rest or nitroglycerin. Nadolol works by blocking beta-1 receptors, thereby slowing heart rate and reducing chest pain during activities.
