Final answer:
The nurse should expect the provider to order Liver Function Tests (LFTs) for a child taking valproic acid, to monitor for potential liver toxicity caused by the medication.
Step-by-step explanation:
A nurse caring for a school-age child on valproic acid should expect the provider to order Liver Function Tests (LFTs). Valproic acid can potentially cause liver toxicity, and it is important to monitor the liver enzymes such as alkaline phosphatase, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) to ensure the liver is functioning normally. These tests are crucial as they can show evidence of liver damage or disease which might be caused by long-term use of valproic acid.
