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.)

Answer and Explanation

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 ["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

A. Bupropion 150 mg PO once per day B. Ibuprofen 200 mg PO q4 to 6 hr PRN pain C. Fluoxetine 20 mg PO QD D. Zolpidem 1.75 mg PO PRN at bedtime

Correct Answer is D

Explanation

A. Bupropion 150 mg PO once per day:
Bupropion 150 mg once daily is a common starting dose, especially for extended-release formulations. This dose is within the recommended range and does not require clarification.

B. Ibuprofen 200 mg PO q4 to 6 hr PRN pain:
Ibuprofen 200 mg every 4 to 6 hours as needed for pain is consistent with typical dosing guidelines for over-the-counter ibuprofen. This prescription is standard and does not require clarification.

C. Fluoxetine 20 mg PO QD:
Fluoxetine 20 mg daily (QD) is a standard starting dose for treating depression. This prescription is appropriate and aligns with common treatment guidelines.

D. Zolpidem 1.75 mg PO PRN at bedtime:
The standard dose for zolpidem is typically 5 mg to 10 mg taken at bedtime for the treatment of insomnia. A dose of 1.75 mg is unusual and lower than the usual recommended dose. Clarification is needed to ensure the dose is correct and appropriate for the client’s needs.
