A nurse is preparing to administer risperidone 1.5 mg PO every 12 hr to a client who has schizophrenia. Available is risperidone solution 1 mg/mL. What is the total daily dose in mL the nurse should 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 ["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.

Explanation
Step-by-Step Calculation
Understanding the Problem
Desired diazepam dose: 15 mg
Available concentration: 5 mg/mL
We need to find the volume to administer.
Calculations
Calculate the volume to administer:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL)
Volume = 15 mg / 5 mg/mL = 3 mL
The nurse should administer 3 mL of diazepam.
Correct Answer is ["150"]
Explanation
Answer
The nurse should identify that 0.15 g is equivalent to 150 mg of desipramine.
Step-by-Step Conversion
Understanding the Problem
We need to convert 0.15 grams (g) to milligrams (mg).
Conversion Factor
1 gram (g) = 1000 milligrams (mg)
Setting Up the Equation
0.15 g X (1000 mg / 1 g) = ? mg
Calculation
Multiply 0.15 by 1000:
0.15 X 1000 = 150 mg
The nurse should identify that 0.15 g is equivalent to 150 mg of desipramine.
