The Correct Answer is ["0.5"]
Identify the desired dose:
The doctor has ordered 0.5 mg of epinephrine.
Identify the available medication concentration:
The available epinephrine injection is 1 mg/mL.
Set up the calculation:
We need to find out how many mL are needed to administer 0.5 mg of the medication. We can use the following formula:
(Desired dose) / (Concentration) = Volume to administer
Plug in the values and calculate:
(0.5 mg) / (1 mg/mL) = 0.5 mL

Explanation
Identify the desired dose:
The doctor has ordered 30 mg of aripiprazole.
Identify the available tablet strength:
Each tablet contains 15 mg of aripiprazole.
Set up the calculation:
We need to find out how many tablets are needed to administer 30 mg of the medication. We can use the following formula:
(Desired dose) / (Tablet strength) = Number of tablets
Plug in the values and calculate:
(30 mg) / (15 mg/tablet) = 2 tablets
Correct Answer is ["1"]
Explanation
Calculate the number of doses per day:
The medication is administered every 8 hours.
There are 24 hours in a day, so there are 24 hours / 8 hours = 3 doses per day.
Calculate the dose per administration:
The total daily dose is 450 mg.
There are 3 doses per day, so each dose is 450 mg / 3 doses = 150 mg.
Calculate the number of tablets per dose:
Each tablet contains 150 mg of bupropion.
The required dose is 150 mg.
150 mg / 150 mg per tablet = 1 tablet per dose
