A nurse is preparing to administer phenelzine 90 mg PO divided in three equal doses daily to a client who has depression. Available is phenelzine 15 mg tablets. How many tablets should the nurse administer per day? (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 ["6"]
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

Explanation
Desired dose: 10 mg
Available concentration: 5 mg/mL
To determine the volume to administer, we can use the following formula:

Volume to administer = 10 mg / (5 mg/mL) = 2 mL
Therefore, the nurse should administer 2 mL of olanzapine.
