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?
(Round the answer to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["10"]

Step 1: Determine the Medication Concentration

The total amount of medication in the solution is 250 mg.
The total volume of the solution is 5 mL.
To find the concentration per mL:
250 mg ÷ 5 mL = 50 mg/mL

Step 2: Determine the Required Volume

The prescribed dose is 500 mg.
To find the volume needed:
500 mg ÷ 50 mg/mL = 10 mL

Thus, the nurse should administer 10 mL of the solution to deliver the required 500 mg dose.

Correct Answer is ["94"]

Explanation

Step 1 is to calculate the rate of infusion. The formula is total volume ÷ total time. So, (750 mL ÷ 8 hr) = 93.75 mL/hr. Rounding to the nearest whole number gives 94 mL/hr.

So, the correct answer is 94 mL/hr.

Correct Answer is ["7.5"]

Explanation

To calculate the volume of fluoxetine to administer, we need to use the formula for dose conversion.

Step 1 is to set up the equation: 30 mg (desired dose) ÷ (20 mg/5 mL). This simplifies to 30 mg × (5 mL/20 mg). The mg units cancel out, leaving us with the volume in mL.

So, the correct answer is 7.5 mL.
