A nurse is preparing to administer amoxapine 300 mg PO to a client. The nurse should identify that this is equivalent to how many g? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.3"]
Step-by-Step Calculation
Understanding the Problem
We need to convert 300 mg to grams.
Calculations
1 gram = 1000 milligrams
To convert milligrams to grams, we divide by 1000.
300 mg = 300 / 1000 = 0.3 g
300 mg is equivalent to 0.3 g.

Correct Answer is C
Explanation
A. Clozapine 12.50 mg PO daily for a client who has schizophrenia:
Clozapine is used for schizophrenia, and the dose of 12.50 mg daily, while on the lower end, is a feasible starting point. Dosage adjustments are common based on the client's response and tolerance.
B. Donepezil 23 mg PO daily for a client who has Alzheimer's disease:
While the typical maximum dose of donepezil is 10 mg daily, some patients may be prescribed higher doses in certain contexts. However, this is less common and may warrant review, but it is not a clear issue compared to the other options.
C. Fluoxetine oral solution 20 mg/5 mL per gastrostomy tube daily for a client who has depression:
Fluoxetine oral solution is often used for depression, but the dosage given as "20 mg/5 mL" per gastrostomy tube daily seems inconsistent with typical dosing practices. This might suggest a misunderstanding or error in prescription, as the exact dose might need to be clarified. The provider should clarify the exact volume to be given to deliver the intended dose.
D. Lamotrigine 200 mg PO daily for a client who has bipolar disorder:
Lamotrigine is commonly used for bipolar disorder, and 200 mg daily is within the standard dosing range. This dosage is generally appropriate for maintenance therapy and does not require clarification.
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.
