A nurse is caring for a client who has a prescription for metoclopramide. Which of the following outcomes should the nurse use to evaluate the effectiveness of this medication?

A. "Suppressed cough": Metoclopramide is a prokinetic agent used primarily to treat gastrointestinal issues like nausea, vomiting, and delayed gastric emptying. It does not affect cough suppression. B. "Relaxed muscles": Metoclopramide does not have muscle relaxant properties. It primarily affects the gastrointestinal system, not muscle relaxation, so this would not be the correct outcome. C. "Reduced nausea": Metoclopramide is commonly used to treat nausea and vomiting, particularly in clients with conditions like gastroesophageal reflux disease (GERD) or after chemotherapy. A reduction in nausea would be a primary indicator of the medication's effectiveness. D. "Decreased pain": While metoclopramide may help improve gastrointestinal motility, it is not specifically used to treat pain. The medication is more focused on relieving nausea and improving gastric emptying rather than addressing pain directly.
