Which medication is used to treat nausea and vomiting?

Oxaliplatin
Olanzapine
Ondansetron

The correct answer is: Ondansetron

Ondansetron is a medication commonly used to treat nausea and vomiting, particularly in patients undergoing chemotherapy, radiation, or surgery. It works by blocking the action of serotonin, a chemical in the body that can trigger nausea and vomiting. While Oxaliplatin is used in some cases to prevent nausea and vomiting caused by chemotherapy, it is primarily used as a chemotherapy medication for treating cancer. Olanzapine is primarily used as an antipsychotic medication, although it may also have antiemetic effects in some cases. Neither of these medications are specifically indicated for nausea and vomiting. Therefore, Ondansetron is the most appropriate and effective option for managing these symptoms.
