Final answer:
Aspirin, Ibuprofen, and Alka Seltzer should be avoided in a patient with an increased risk of bleeding due to bone marrow suppression. Acetaminophen can be used as a safer alternative.
Step-by-step explanation:
In a patient with an increased risk of bleeding due to bone marrow suppression, aspirin, Ibuprofen, and Alka Seltzer should be avoided.
Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) can increase the risk of gastrointestinal ulcers and bleeds. Ibuprofen is also an NSAID, so it carries the same risk. Alka Seltzer contains aspirin, so it should be avoided as well.
Instead, acetaminophen can be used as an alternative analgesic and antipyretic agent, as it does not inhibit platelet aggregation and is not useful for preventing vascular clotting.
