To reduce emphysema
To decrease carbon dioxide retention
The Correct Answer is B
A. Aspirin is not primarily used to inhibit peptic ulcer disease; it is used to prevent cardiovascular events by decreasing platelet aggregation.
B. Aspirin decreases platelet aggregation, making it useful in preventing clot formation in conditions such as angina and myocardial infarction.
