A nurse is preparing to administer olanzapine 10 mg IM to a client who has schizophrenia. Available is olanzapine 5 mg/mL. How many mL should the nurse administer? (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 ["2"]
Desired dose: 10 mg
Available concentration: 5 mg/mL
To determine the volume to administer, we can use the following formula:
Volume to administer (mL) = Desired dose (mg) / Concentration (mg/mL)
Volume to administer = 10 mg / (5 mg/mL) = 2 mL
Therefore, the nurse should administer 2 mL of olanzapine.

Correct Answer is ["6"]
Explanation
Step-by-Step Calculation
Understanding the Problem
Total daily dose of phenelzine: 90 mg
Divided into 3 equal doses
Strength of each tablet: 15 mg
We need to find the total number of tablets per day.
Calculations
Calculate the dose per administration:
Dose per administration = Total daily dose / Number of doses
Dose per administration = 90 mg / 3 = 30 mg
Calculate the number of tablets per dose:
Tablets per dose = Dose per administration / Tablet strength
Tablets per dose = 30 mg / 15 mg/tablet = 2 tablets
The nurse should administer 2 tablets per day.
Since the client will receive 2 tablets per dose and will take 3 doses per day, the total number of tablets for the day is:
2 tablets/dose × 3 doses/day = 6 tablets/day
Correct Answer is ["1"]
Explanation
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.
