Final answer:
The nurse should monitor and report elevated liver enzymes in a client taking valproic acid, as this could indicate hepatotoxicity and potential liver damage that requires immediate attention. The correct multiple-choice option is (c).
Step-by-step explanation:
A nurse caring for a client taking valproic acid for seizure control should monitor for several potential adverse effects. Among these, one of the most important to watch for is elevated liver enzymes. This is because valproic acid can cause hepatotoxicity, which can lead to liver injury. Regular monitoring of liver function tests is essential to detect any hepatotoxicity early on. The nurse should report elevated liver enzymes to the healthcare provider immediately as it may signify potential liver damage.
It is also important to note that hepatic encephalopathy is a severe and potentially reversible neuropsychiatric complication that can arise in the setting of chronic or acute liver failure. While this condition is not directly caused by valproic acid, any signs of liver dysfunction could potentially contribute to its development, making the monitoring of liver enzymes even more crucial.
The correct multiple-choice option is (c).
