Answer and Explanation

The Correct Answer is ["0.6"]

1. Dosage and Concentration:

Haloperidol dose to be administered: 3 mg

Concentration of available haloperidol injection: 5 mg/mL

2. Volume Calculation:

We can determine the volume to administer using the following formula:

Volume (mL) = Dose (mg) / Concentration (mg/mL)

3. Calculating the Volume:

Plugging in the values:

Volume (mL) = 3 mg / 5 mg/mL

4. Rounding the Answer:

The calculated volume is 0.6 mL. Rounding to the nearest tenth:

Volume (mL) = 0.6 mL (rounded)

Therefore, the nurse should administer 0.6 mL of haloperidol injection

Correct Answer is C

Explanation

A) Route: The prescription already specifies the route of administration as topical, which indicates that the cream should be applied to the skin. Therefore, there is no need to add the route to the prescription.

B) Medication name: The prescription clearly states the medication name, hydrocortisone acetate cream. The nurse does not need to ask for clarification or addition of the medication name.

C) Dose/strength: The prescription does not specify the strength or concentration of the hydrocortisone acetate cream, which is crucial for proper administration and effectiveness. Hydrocortisone creams come in various strengths, and using the incorrect strength could result in inadequate treatment or potential side effects.

D) Time/frequency: The prescription already includes the frequency, specifying that the cream should be applied twice a day. Thus, there is no need to add the time/frequency to the prescription.

Correct Answer is ["0.75"]

Explanation

1. Dosage and Concentration:

Methylprednisolone acetate dosage: 60 mg

Methylprednisolone acetate concentration: 80 mg/mL (available suspension)

2. Volume Calculation:

We can use the following formula to find the volume to administer:

Volume (mL) = Dosage (mg) / Concentration (mg/mL)

Volume (mL) = 60 mg / 80 mg/mL

3. Rounding the Answer:

Round the answer to the nearest hundredth of a milliliter.

Volume (mL) = 0.75 mL (rounded to two decimal places)

Therefore, the nurse should administer 0.75 mL of methylprednisolone acetate suspension for injection.
