Answer and Explanation

The Correct Answer is ["3"]

tep-by-Step Solution

Understanding the Problem

The client needs risperidone 1.5 mg every 12 hours.

We have risperidone solution 1 mg/mL.

We need to find the total daily dose in mL.

Step 1: Calculate the total daily dose in mg

The client receives 1.5 mg every 12 hours.

There are 2 doses in a day (every 12 hours).

So, the total daily dose in mg is 1.5 mg/dose X 2 doses = 3 mg.

Step 2: Convert mg to mL

We know that 1 mg of risperidone is in 1 mL of solution.

We have a total daily dose of 3 mg.

So, to find the volume in mL, we can set up a proportion:

1 mg / 1 mL = 3 mg / x mL

Step 3: Solve for x

Cross-multiply: 1 mg X x mL = 1 mL X 3 mg

Simplify: x mL = 3 mL

Therefore, the nurse should administer a total daily dose of 3 mL.

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.

Correct Answer is ["2"]

Explanation

The nurse should administer 2 mL of risperidone.

Step-by-Step Calculation

Understanding the Problem

Desired risperidone dose: 25 mg

Available concentration: 25 mg/2 mL

We need to find the volume to administer.

Calculations

Since the desired dose (25 mg) is equal to the concentration per mL (25 mg/2 mL), we can directly administer the entire 2 mL vial.

The nurse should administer 2 mL of risperidone.
