A nurse is preparing to administer chlorpromazine hydrochloride 40 mg IM to a client who has anorexia nervosa. Available is chlorpromazine hydrochloride injection 25 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.6"]
Step-by-Step Calculation
Understanding the Problem
Desired dose: 40 mg of chlorpromazine hydrochloride
Available concentration: 25 mg/mL
Calculations
Calculate the volume to administer:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL)
Volume = 40 mg / 25 mg/mL = 1.6 mL
The nurse should administer 1.6 mL of chlorpromazine hydrochloride.

Correct Answer is ["3"]
Explanation
The nurse should administer 3 mL of benztropine mesylate.
Step-by-Step Calculation
Understanding the Problem
Desired dose: 3 mg benztropine mesylate
Available concentration: 1 mg/mL benztropine mesylate
Setting Up the Equation
We can use the following formula:
Desired dose (mg) = Concentration (mg/mL) X Volume (mL)
We need to find the volume (mL).
Calculating the Volume
3 mg = 1 mg/mL X Volume (mL)
To isolate Volume, we divide both sides by 1 mg/mL:
Volume (mL) = 3 mg / (1 mg/mL)
Volume (mL) = 3 mL
The nurse should administer 3 mL of benztropine mesylate.
Correct Answer is ["0.5"]
Explanation
The nurse should administer 0.5 ml of ziprasidone injection.
Step-by-Step Calculation
Understanding the Problem
We need to administer 10 mg of ziprasidone.
The available concentration is 20 mg/ml.
We need to find out how many milliliters (ml) to administer.
Setting up the Equation
We can use the formula:
Desired dose (mg) = Concentration (mg/ml) X Volume (ml)
Calculating the Volume
We know the desired dose (10 mg) and the concentration (20 mg/ml). We need to findthe volume.
Rearranging the formula to solve for volume, we get:
Volume (ml) = Desired dose (mg) / Concentration (mg/ml)
Substituting the values:
Volume (ml) = 10 mg / 20 mg/ml = 0.5 ml
The nurse should administer 0.5 ml of ziprasidone injection.
