Answer to Question 1

A
In cor pulmonale, the heart is affected because a lung condition interferes with the exchange of carbon dioxide and oxygen in the alveoli. This can result in right-sided heart failure.

Answer to Question 2

A
Some of the factors that contribute to the increasing incidence of STIs include increase in casual sexual encounters, particularly with unprotected sex; nonbarrier methods of birth control; existence of asymptomatic disease carriers; unfamiliarity with methods of preventing STIs; increased use of alcohol and illegal drugs, including needle sharing among intravenous drug users and trading sex for drugs; and inadequate reporting of STIs.
