Final answer:
Ketorolac may lead to gastrointestinal bleeding in addition to its other serious side effects, which are particularly risky for certain groups of people.
Step-by-step explanation:
Ketorolac may increase bleeding, acute renal failure, liver failure, and gastrointestinal bleeding (Option A). This non-steroidal anti-inflammatory drug (NSAID) is known for its powerful analgesic and anti-inflammatory properties, but it also has a profile of potential negative side effects. Key points to remember with NSAIDs include an increased risk for stomach bleeding, especially in individuals over 60, those on blood thinners or steroids, those with a history of stomach ulcers, or those with other bleeding disorders. Furthermore, the use of NSAIDs can lead to kidney damage, particularly in those with high blood pressure, heart disease, or pre-existing kidney disease.
