Question 1 of 5

Question 2 of 5
Pharmacologic actions of acetylsalicylic acid include all of the following EXCEPT:
Correct Answer: C
Rationale: Acetylsalicylic acid (aspirin) inhibits COX enzymes, reducing prostaglandin synthesis (choice D), yielding analgesic (choice A) and antipyretic (choice B) effects by decreasing pain mediators and hypothalamic heat regulation, respectively. However, it inhibits, not promotes, platelet aggregation (choice C) by blocking thromboxane A2 production, a pro-aggregatory prostaglandin, making it antiplatelet, used in cardiovascular prophylaxis. Promotion of aggregation would contradict its mechanism. This exception tests understanding of aspirin's unique antiplatelet action among NSAIDs, critical for its clinical applications.
