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 ["15"]

Explanation

Step 1 is to determine the amount of amantadine needed, which is 150 mg as prescribed.

Step 2 is to calculate the volume of the solution needed to deliver this dose. The available solution has a concentration of 50 mg per 5 mL. Using the formula:

(Prescribed dose ÷ Available dose) × Volume per dose

(150mg ÷ 50mg) × 5mL = 15mL

Therefore, the correct answer is 15 mL.

Correct Answer is ["2"]

Explanation

Step 1 is to determine the amount of lorazepam needed, which is 2 mg as prescribed.

Step 2 is to calculate the number of tablets required. Since each tablet contains 1 mg, we divide the prescribed dose by the strength per tablet:

2 mg ÷ 1 mg per tablet = 2 tablets

Therefore, the correct answer is 2 tablets.
