A nurse is caring for a client who has a new prescription for alosetron.Which of the following therapeutic effects should the nurse expect the client to experience?

Choice A rationaleAlosetron does not significantly impact gastric acid production. Its primary function is to modulate serotonin receptors in the gut, not to alter the secretion of gastric acids.Choice B rationaleAlosetron, a serotonin receptor antagonist, is used to treat irritable bowel syndrome (IBS) by decreasing the frequency of defecation. It slows colonic transit time, reducing bowel movements.Choice C rationaleAlosetron decreases gastric motility rather than increasing it. It works by slowing down the movements of the intestines, which helps to manage diarrhea-predominant IBS.Choice D rationaleAlosetron's mechanism does not include increasing the absorption of water into the intestine. It primarily affects the neurotransmitters involved in bowel movement regulation.
