A client diagnosed with metastatic cancer is preparing for discharge. The physician orders morphine sulfate controlled-release tablets

A client diagnosed with metastatic cancer is preparing for discharge. The physician orders morphine sulfate controlled-release tablets 100 mg every 12 hours as needed after discharge. What legal rights and responsibilities should the nurse address when teaching the client about morphine sulfate use? “You must avoid driving or other activities that require alertness while taking controlled-release morphine sulfate.” “Morphine sulfate is an opioid and you may develop a tolerance to it. This is an expected response and is not harmful.” “If you no longer require the morphine sulfate controlled-release tablets for your cancer pain, do not take any leftover pills for other disorders.” “Federal law prevents refills of this medication. Your physician will give you a new prescription when you need more medicine.”
