What is the action of antiemetics?

Stimulate appetite and digestion
Suppress nausea and vomiting
Increase gastric acid secretion
Act as a laxative

The correct answer is: Suppress nausea and vomiting

Antiemetics are medications specifically designed to suppress nausea and vomiting, making option B the correct choice. These medications work on various pathways in the body to block signals that trigger the vomiting reflex. They may target receptors in the brain, such as serotonin receptors in the central nervous system and the gastrointestinal tract, to prevent the sensation of nausea and the act of vomiting. Other listed actions do not align with the primary role of antiemetics. For instance, stimulating appetite and digestion pertains more to medications that enhance gastrointestinal activity rather than suppress nausea. Increasing gastric acid secretion relates to drugs that target acid production in the stomach, which can sometimes exacerbate nausea rather than mitigate it. Acting as a laxative involves promoting bowel movements, another action not associated with stopping nausea or vomiting, but rather dealing with constipation issues. Thus, the core function of antiemetics is to effectively manage and reduce symptoms of nausea and vomiting, confirming that option B is the correct understanding of their action.
