Answer to Question 1

Correct Answer: 1
Class II beta-blockers such as propranolol are used to reduce heart rate and myocardial contractility and in the treatment of supraventricular tachycardia. These drugs may cause bronchospasm and are contraindicated for patients with asthma, chronic obstructive pulmonary disease (COPD), or other restrictive or obstructive lung diseases. Antioxidants and simvastatin may be taken concurrently with propranolol. Bleeding disorders are not associated with propranolol use.

Answer to Question 2

Correct Answer: 1, 2, 4, 5
Cardiovascular benefits of exercise include increased availability of oxygen to the heart muscle, decreased oxygen demand and cardiac workload, and increased myocardial function and electrical stability. Other positive effects of regular physical activity include decreasing blood pressure and platelet aggregation.
