A nurse is reviewing laboratory data for a client who has a new prescription for valproic acid. Which of the following baseline results should the nurse review prior to administering the first dose of the medication?
Potassium level
Thyroid function tests
Uric acid level
Liver function tests
The Correct Answer is D
A. Potassium level – Valproic acid does not significantly affect potassium levels, so this is not a necessary baseline test.
B. Thyroid function tests – Valproic acid is not known to significantly impact thyroid function, making this an unnecessary test.
C. Uric acid level – Uric acid levels are more relevant for conditions like gout, and valproic acid does not typically cause hyperuricemia.
D. Liver function tests – This is the correct answer because valproic acid is metabolized in the liver and can cause hepatotoxicity. Baseline liver function tests (LFTs) should be reviewed before starting the medication to assess liver health.

B. A child who has a urinary tract infection and bright red blood in her urine – Hematuria can be concerning but is not immediately life-threatening.
C. A child who has mononucleosis and reports severe fatigue – Fatigue is common with mononucleosis but does not require immediate intervention.
D. A child who has Wilms' tumor and an abdominal mass – While Wilms' tumor is serious, it does not present an immediate airway or hemodynamic emergency.
