A nurse is caring for a client who had total hip arthroplasty 1 day ago and is receiving morphine sulfate by PCA pump for pain control.The client reports nausea and vomiting.Which of the following actions should the nurse take?

Choice A rationaleNausea and vomiting are common side effects of morphine sulfate, an opioid analgesic administered via a PCA pump. An antiemetic medication directly addresses these symptoms and improves patient comfort.Choice B rationaleEncouraging the use of an incentive spirometer is important for preventing postoperative respiratory complications, but it does not directly address the client's current nausea and vomiting.Choice C rationaleAuscultating bowel sounds is important for assessing gastrointestinal function, but it does not provide immediate relief from nausea and vomiting. While changes in bowel sounds could indicate a problem, addressing the symptom with an antiemetic is the priority.Choice D rationaleInserting a nasogastric tube is an invasive procedure typically reserved for persistent vomiting, bowel obstruction, or gastric decompression. It is not the first-line intervention for nausea and vomiting related to opioid use.
