Question 1 of 5
A nurse is preparing to administer valproic acid 500 mg PO. Available is valproic acid oral solution 250 mg/5 mL. How many mL should the nurse administer?
Correct Answer: A
Rationale: The correct answer is A: 10 mL.
To determine this, the nurse needs to use the formula: Desired Dose / Stock Concentration = Volume to Administer. In this case, the desired dose is 500 mg and the stock concentration is 250 mg/5 mL.
Therefore, 500 mg / 250 mg/5 mL = 10 mL. This calculation ensures the nurse administers the correct dose of valproic acid. Other choices are incorrect as they do not follow the correct calculation process or would result in an incorrect dosage.
