A nurse is caring for a client who has a new prescription for bupropion 450 mg PO daily divided equally every 3 hr. Available is bupropion 150 mg sustained-release tablets. How many tablets 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 ["1"]
Step-by-Step Calculation
Understanding the Problem
Total daily dose of bupropion: 450 mg
Divided equally every 3 hours
Available tablets: 150 mg sustained-release
Calculating Doses per Day
There are 24 hours in a day.
Dividing the day into 3-hour intervals: 24 hours / 3 hours/dose = 8 doses per day
Calculating Dose per Administration
Total daily dose / Number of doses per day = Dose per administration
450 mg / 8 doses = 56.25 mg/dose
Determining Number of Tablets per Dose
Dose per administration / Strength of tablet = Number of tablets
56.25 mg/dose / 150 mg/tablet = 0.375 tablets/dose
Rounding and Adjusting
Since we can't administer part of a tablet, we round up to the nearest whole number: 1 tablet/dose.
The nurse should administer 1 tablet of bupropion 150 mg sustained-release per dose.

Correct Answer is ["1.5"]
Explanation
Answer
The nurse should administer 1.5 mL of haloperidol.
Step-by-Step Calculation
Understanding the Problem
Desired dose: 75 mg haloperidol
Available concentration: 50 mg/mL
We need to find the volume to administer.
Calculations
Calculate the volume to administer:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL)
Volume = 75 mg / 50 mg/mL = 1.5 mL
The nurse should administer 1.5 mL of haloperidol.
Correct Answer is ["0.5"]
Explanation
To calculate the volume of naloxone to administer, we can use the following formula:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL)
In this case:
Desired dose = 0.2 mg
Concentration = 0.4 mg/mL
Plugging these values into the formula, we get:
Volume (mL) = 0.2 mg / 0.4 mg/mL = 0.5 mL
Therefore, the nurse should administer 0.5 mL of naloxone.
