A nurse is caring for a client who is taking valproic acid for seizure control. For which of the following adverse effects should the nurse monitor and report?

A. Weight loss is not a common or serious adverse effect of valproic acid. Valproic acid can cause weight gain, not weight loss. B. Jaundice is a sign of liver damage, which is a serious and potentially fatal adverse effect of valproic acid. Valproic acid can impair fatty acid metabolism and mitochondrial function, leading to hepatotoxicity and steatosis. The nurse should monitor the client's liver function tests and report any signs of jaundice, such as yellowing of the skin or eyes, dark urine, or clay-colored stools . C. Bradycardia is not a common or serious adverse effect of valproic acid. Valproic acid can cause cardiac arrhythmias, but they are usually tachycardic, not bradycardic. D. Polyuria is not a common or serious adverse effect of valproic acid. Valproic acid can cause hypernatremia and hypocalcemia, which can affect urine output, but polyuria is not a specific symptom of these electrolyte imbalances.
