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 ["1.5"]
Explanation
Identify the desired dose:
The doctor has ordered 75 mg of hydroxyzine hydrochloride.
Identify the concentration of the available medication
The available hydroxyzine hydrochloride injection is 50 mg/mL.
Set up the calculation:
We need to find out how many mL are needed to administer 75 mg of the medication. We can use the following formula:
(Desired dose) / (Concentration) = Volume to administer
Plug in the values and calculate:
(75 mg) / (50 mg/mL) = 1.5 mL
