What is the function of anti-emetics?

  1. Control high blood pressure

  2. Treat overactive bowels

  3. Relieve nausea and vomiting

  4. Regulate the heartbeat

The correct answer is: Relieve nausea and vomiting

Anti-emetics are medications designed to relieve nausea and vomiting. These drugs work by blocking signals in the brain that trigger nausea and vomiting. They are commonly used in various situations such as post-surgery, chemotherapy, motion sickness, or gastrointestinal issues. Option A, controlling high blood pressure, is incorrect as anti-emetics do not have an effect on blood pressure. Option B, treating overactive bowels, is incorrect as this function relates more to antidiarrheal medications. Option D, regulating the heartbeat, is incorrect as anti-emetics do not directly affect heart function.
