A nurse is caring for a 78-year-old male client admitted to the Surgical unit after having a total right knee replacement. Exhibits The nurse reviews the client's nursing note, vital signs, and medication administration record (MAR). Based on the findings, which medication is appropriate for the client? Complete the following sentence by using the lists of options regarding the post-operative client: The nurse should understand that dropdown on a pain scale that is less than 3 should be given only if the client reports mild pain.

The correct answer is Choice B. Choice A rationale: Ondansetron (Zofran) is an antiemetic used to prevent nausea and vomiting. The client denies nausea and vomiting, so this medication is not necessary at this time. Choice B rationale: Acetaminophen (Tylenol) is appropriate for managing mild pain, which the client reports as 2 out of 10 on the pain scale. This medication effectively alleviates mild pain without significant side effects, making it suitable for the client’s current condition. Choice C rationale: Hydrocodone/Acetaminophen (Norco) is a combination of an opioid and acetaminophen used for moderate to severe pain. Since the client reports only mild pain (2 out of 10), this stronger medication is not warranted and could cause unnecessary side effects. Choice D rationale: Melatonin is used to help with sleep. The client does not report any issues with sleep, so administering this medication is not relevant to the current situation.
