A nurse is preparing to administer amantadine 150 mg PO for a client who is experiencing parkinsonism due to an antipsychotic medication.

Available is amantadine 50 mg/5 mL oral solution.

How many mL should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["15"]

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 ["3"]

Explanation

Step 1 is to determine the total amount of medication needed, which is 750 mg. Step 2 is to convert the medication needed into mL using the medication’s concentration. So, 750 mg ÷ (250 mg/5 mL) = 15 mL.

So, the correct answer is 15 mL.

Correct Answer is ["10"]

Explanation

Step 1 is to calculate the amount of hydroxyzine HCL in each mL of the oral suspension. This is done by dividing the total amount of hydroxyzine HCL (25 mg) by the total volume (5 mL), which gives us 5 mg/mL. Step 2 is to calculate the volume of oral suspension that contains 50 mg of hydroxyzine HCL. This is done by dividing the prescribed dose (50 mg) by the concentration of the oral suspension (5 mg/mL). So, 50 mg ÷ 5 mg/mL = 10 mL.

So, the correct answer is 10 mL.
