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.

Correct Answer is ["0.5"]
Explanation
Step 1: The total amount of digoxin required per dose is 125 mcg. We need to convert this to mg because the available tablets are in mg. We know that 1 mg = 1000 mcg, so 125 mcg = 125 ÷ 1000 mg = 0.125 mg.
Step 2: Each tablet contains 0.25 mg of digoxin.
Step 3: To find out how many tablets are needed, we divide the total amount required by the amount in each tablet. So, (0.125 mg ÷ 0.25 mg/tablet).
Step 4: The result is 0.5 tablets.
So, the nurse should administer 0.5 tablets per dose. This is already rounded to the nearest tenth.
Correct Answer is B
