A nurse is preparing to administer enalapril at 5 mg IV bolus. Available is enalapril injection 25 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["4"]

Identify the Desired Dose and Available Concentration:

Desired Dose: 5 mg of enalapril

Available Concentration: 1.25 mg/mL (This means there are 1.25 mg of enalapril in every 1 mL of solution)

Set up the Calculation:

We need to find the volume (in mL) that contains the desired dose of 5 mg.

We can use the following formula:

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

Plug in the Values and Calculate:

Volume (mL) = 5 mg / 1.25 mg/mL

Volume (mL) = 4 mL

Round to the Nearest Whole Number (if necessary):

4 mL

Correct Answer is ["6"]

Explanation

Order: Dopamine 2 mcg/kg/min

Client Weight: 176 lbs

Available Solution: Dopamine 400 mg in 250 mL of D5W

Desired Rate: mL/hr

Convert Client Weight to Kilograms (kg)

1 kg = 2.2 lbs

Client Weight in kg: 176 lbs / 2.2 lbs/kg = 80 kg

Step 2: Calculate the Dopamine Dose per Minute

Dose: 2 mcg/kg/min

Client Weight: 80 kg

Total Dose per Minute: 2 mcg/kg/min x 80 kg = 160 mcg/min

Step 3: Convert Dopamine Dose to Milligrams (mg)

1 mg = 1000 mcg

Dose in mg/min: 160 mcg/min / 1000 mcg/mg = 0.16 mg/min

Step 4:Calculate the Dopamine Dose per Hour

Dose in mg/min: 0.16 mg/min

Minutes in an Hour: 60 min

Dose in mg/hr: 0.16 mg/min x 60 min/hr = 9.6 mg/hr

Step 5: Determine the Concentration of the Dopamine Solution

Available Dopamine: 400 mg

Solution Volume: 250 mL

Concentration: 400 mg / 250 mL = 1.6 mg/mL

Step 6: Calculate the Infusion Rate in mL/hr

Dose in mg/hr: 9.6 mg/hr

Concentration: 1.6 mg/mL

Infusion Rate: 9.6 mg/hr / 1.6 mg/mL = 6 mL/hr

Step 7: Round to the Nearest Whole Number

The calculated rate is 6 mL/hr, which is already a whole number.

Answer: 6 mL/hr

A. A total 62.5 mL is available in this dose B. This medication can be administered IM only C. This medication should be protected from light D. The medication is effective for 7 days after reconstitution

Correct Answer is C

Explanation

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.
