A nurse is preparing to administer ziprasidone 10 mg IM to a client who has acute agitation and schizophrenia. Available is ziprasidone injection 20 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 ["0.5"]
The nurse should administer 0.5 mL of ziprasidone.
Step-by-Step Calculation
Understanding the Problem
Desired ziprasidone dose: 10 mg
Available concentration: 20 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 = 10 mg / 20 mg/mL = 0.5 mL
The nurse should administer 0.5 mL of ziprasidone.

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
Correct Answer is ["1.2"]
Explanation
Answer
The nurse should administer 1.2 mL of fluphenazine hydrochloride.
Step-by-Step Calculation
Understanding the Problem
Desired dose: 3 mg fluphenazine hydrochloride
Available concentration: 2.5 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 = 3 mg / 2.5 mg/mL = 1.2 mL
The nurse should administer 1.2 mL of fluphenazine hydrochloride.
