A nurse is reviewing new prescriptions for a group of clients. Which of the following prescriptions should the nurse clarify with the provider?

Clozapine 12.50 mg PO daily for a client who has schizophrenia

Donepezil 23 mg PO daily for a client who has Alzheimer's disease

Fluoxetine oral solution 20 mg/5 mL per gastrostomy tube daily for a client who has depression

Lamotrigine 200 mg PO daily for a client who has bipolar disorder

Answer and Explanation

The Correct Answer is C

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 ["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.

Correct Answer is ["0.5"]

Explanation

The nurse should administer 0.5 mL of epinephrine.

Step-by-Step Calculation

Understanding the Problem

Desired dose: 0.5 mg epinephrine

Available concentration: 1 mg/mL epinephrine

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

0.5 mg = 1 mg/mL X Volume (mL)

To isolate Volume, we divide both sides by 1 mg/mL:

Volume (mL) = 0.5 mg / (1 mg/mL)

Volume (mL) = 0.5 mL

The nurse should administer 0.5 mL of epinephrine.
