A nurse is preparing to administer PRN pain medication to a client who has cholelithiasis and is experiencing moderate abdominal pain. Which of the following medications should the nurse plan to administer?

A) Acetaminophen: While acetaminophen can be effective for mild to moderate pain relief, it may not be the most appropriate choice for abdominal pain associated with cholelithiasis. Opioids or nonsteroidal anti-inflammatory drugs (NSAIDs) like ketorolac are typically more effective for this type of pain. B) Omeprazole: This medication is a proton pump inhibitor used primarily for reducing gastric acid secretion and is not indicated for pain management. It does not address the pain caused by cholelithiasis. C) Metoclopramide: This medication is an antiemetic and prokinetic agent that may help with nausea and vomiting, but it does not directly alleviate pain. It would not be the first choice for pain management in this situation. D) Ketorolac: This NSAID is effective for managing moderate to severe pain and is suitable for the type of pain associated with cholelithiasis. It has anti-inflammatory properties that can provide significant relief, making it the best option for the client's current symptoms.
