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 C
Explanation
A. Clozapine 12.50 mg PO daily for a client who has schizophrenia:
Clozapine is used for schizophrenia, and the dose of 12.50 mg daily, while on the lower end, is a feasible starting point. Dosage adjustments are common based on the client's response and tolerance.
B. Donepezil 23 mg PO daily for a client who has Alzheimer's disease:
While the typical maximum dose of donepezil is 10 mg daily, some patients may be prescribed higher doses in certain contexts. However, this is less common and may warrant review, but it is not a clear issue compared to the other options.
C. Fluoxetine oral solution 20 mg/5 mL per gastrostomy tube daily for a client who has depression:
Fluoxetine oral solution is often used for depression, but the dosage given as "20 mg/5 mL" per gastrostomy tube daily seems inconsistent with typical dosing practices. This might suggest a misunderstanding or error in prescription, as the exact dose might need to be clarified. The provider should clarify the exact volume to be given to deliver the intended dose.
D. Lamotrigine 200 mg PO daily for a client who has bipolar disorder:
Lamotrigine is commonly used for bipolar disorder, and 200 mg daily is within the standard dosing range. This dosage is generally appropriate for maintenance therapy and does not require clarification.
Correct Answer is A
Explanation
A. Divalproex 1.5 g PO twice daily:
Divalproex (valproic acid) is used for managing mania and typically dosed between 750 mg and 3 g daily, depending on the specific needs of the client and their blood levels. However, 1.5 g twice daily (3 g total daily) might be higher than usual initial dosing and could warrant clarification to ensure that this is an appropriate dose for the client and does not exceed recommended maximums.
B. Lithium 300 mg PO three times daily:
Lithium is commonly prescribed for mania, and 300 mg three times daily is a standard dosing regimen. Lithium levels are monitored to ensure therapeutic efficacy and avoid toxicity, so this dosage is within a typical range.
C. Clonazepam 0.5 mg PO three times daily:
Clonazepam is a benzodiazepine that can be used to manage anxiety or agitation associated with mania. A dose of 0.5 mg three times daily is within the usual range for short-term management and does not typically require clarification.
D. Risperidone 3.0 mg PO daily:
Risperidone is an atypical antipsychotic used to manage symptoms of mania, and 3 mg daily is a common starting dose. This dosage is appropriate and generally does not require further clarification.
