A nurse is reconciling the medications of a client who was newly admitted for management of mania. Which of the following prescriptions should the nurse clarify with the provider?
Divalproex 1.5 g PO twice daily
Lithium 300 mg PO three times daily
Clonazepam 0.5 mg PO three times daily
Risperidone 3.0 mg PO daily
The Correct Answer is A
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.

Step-by-Step Calculation
Understanding the Problem
Desired valproic acid dose: 375 mg
Available capsules: 125 mg each
We need to find the number of capsules to administer.

The dose of 2 mg is clearly specified in the prescription and does not need further clarification. It is the correct amount to administer based on the provided information.

The frequency is indicated as "every 4 hr PRN" (as needed), which specifies how often the medication can be given. There is no need for further clarification regarding the frequency.
