Its primary use is for gastrointestinal symptoms like nausea. Cough is not a relevant measure of its effectiveness.Choice C rationaleMuscle relaxation is not an expected outcome of metoclopramide. It mainly targets gastrointestinal motility and nausea. Other medications are more appropriate for muscle relaxation.Choice D rationaleMetoclopramide does not typically target pain relief. It is used for nausea and gastrointestinal motility disorders. Assessing pain reduction is not relevant for this medication. .
