A nurse is preparing to administer amantadine 150 mg PO every 12 hours. Available is amantadine 50 mg/5 mL syrup. How many mL should the nurse administer per dose?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["15"]
Step 1: The total amount of amantadine required per dose is 150 mg.
Step 2: Each 5 mL of syrup contains 50 mg of amantadine.
Step 3: To find out how many mL are needed, we divide the total amount required by the amount in each 5 mL of syrup. So, (150 mg ÷ 50 mg/5 mL).
Step 4: The result is 15 mL.
So, the nurse should administer 15 mL per dose. This is already a whole number, so no rounding is necessary.
