A nurse is preparing to administer methylprednisolone 250 mg IV to a client. Which of the following information should the nurse interpret from the medication label?
A total 62.5 mL is available in this dose
This medication can be administered IM only
This medication should be protected from light
The medication is effective for 7 days after reconstitution
The Correct Answer is C
A. A total 62.5 mL is available in this dose: The label states that each mL of the reconstituted solution contains 62.5 mg of methylprednisolone. However, the total volume available depends on the reconstitution process, and this option does not directly match the provided information.
B. This medication can be administered IM only: The label clearly states that the medication can be given both intramuscularly (IM) and intravenously (IV), making this option incorrect.
C. This medication should be protected from light: The label explicitly instructs to protect the medication from light, confirming this as the correct answer.
D. The medication is effective for 7 days after reconstitution: The label specifies that the medication should be used within 48 hours after reconstitution, not 7 days.

Correct Answer is ["38"]
Explanation
Convert Grams to Milligrams:
The available lidocaine is 1 gram (g).
We need to convert this to milligrams (mg) because the dose is in mg/min.
There are 1000 milligrams in 1 gram (1 g = 1000 mg).
So, 1 g x 1000 mg/g = 1000 mg
Calculate the Lidocaine Concentration in mg/mL:
Available lidocaine: 1000 mg
Total volume: 250 mL
Concentration: 1000 mg / 250 mL = 4 mg/mL
Calculate the Lidocaine Dose in mg/hr:
Dose: 2.5 mg/min
There are 60 minutes in 1 hour.
Dose in mg/hr: 2.5 mg/min x 60 min/hr = 150 mg/hr
Calculate the Infusion Rate in mL/hr:
Concentration: 4 mg/mL
Dose in mg/hr: 150 mg/hr
Infusion Rate (mL/hr) = Dose in mg/hr / Concentration (mg/mL)
Infusion Rate (mL/hr) = 150 mg/hr / 4 mg/mL = 37.5 mL/hr
Round to the Nearest Whole Number:
38 mL/hr
Correct Answer is ["0.4"]
Explanation
Identify the Desired Dose and Available Concentration:
Desired Dose: 0.4 mg of naloxone
Available Concentration: 1 mg/mL (This means there is 1 mg of naloxone in every 1 mL of solution)
Set up the Calculation:
We need to find the volume (in mL) that contains the desired dose of 0.4 mg.
We can use the following formula:
Volume (mL) = Desired Dose (mg) / Available Concentration (mg/mL)
Plug in the Values and Calculate:
Volume (mL) = 0.4 mg / 1 mg/mL
Volume (mL) = 0.4 mL
Round to the Nearest Tenth (if necessary):
0.4 mL
