Answer to Question 1

Ans: B
Overall regulation of blood pressure and heart rate becomes less responsive and less efficient with age. Veins become thicker and stiffer. Heart rate does not typically slow with age and valvular regurgitation is considered a pathologic condition at any age.

Answer to Question 2

Ans: A
Smoking is a major risk factor for cardiovascular disease. Benefits of smoking cessation as a secondary prevention intervention begin immediately and are as effective in older adults as they are in younger people. Additional lifestyle interventions that are effective for preventing cardiovascular disease include remaining physically active, managing stress, and maintaining ideal body weight.
