A client is receiving IV dextrose 5% in water (D5W) at 125 mL/hour and a secondary infusion of pantoprazole 40 mg IV daily. The pharmacy provides a 110 mL premixed solution of pantoprazole to be infused over 15 minutes. The nurse should program the secondary infusion to deliver how many mL/hour? (Enter numeric value only.)
Answer and Explanation

The Correct Answer is ["440"]

The pharmacy provides a 110 mL premixed solution of pantoprazole to be infused over 15 minutes.

First, let’s find out how many mL should be delivered per minute. 

We divide the total volume by the total time in minutes:

Rate in mL/min = 110 mL /15 min  ​≈  7.33 mL/min

We need to convert this to mL/hr since we want the rate in mL/hr. 

There are 60 minutes in an hour, so:

Rate in mL/hr = 7.33 mL/min×60 = 440 mL/hr

So, the nurse should program the secondary infusion to deliver 440 mL/hr.

Correct Answer is ["0.5"]

Explanation

Here's how to calculate the volume (mL) of filgrastim the nurse should administer:

1. Client weight conversion:

Client weight: 132 pounds

Medication dosage is based on weight per kilogram (kg).

Conversion factor: 1 kg = 2.205 lbs

Client weight (kg): 132 pounds / 2.205 lbs/kg = 60 kg (round to nearest whole number)

2. Filgrastim dosage:

Prescribed dose: 5 mcg/kg/day (given)

3. Daily filgrastim amount:

Daily dose (mcg) = Dose (mcg/kg/day) x Client weight (kg)

Daily dose (mcg) = 5 mcg/kg/day * 60 kg

Daily dose (mcg) = 300 mcg (round to nearest whole number)

4. Filgrastim vial concentration:

The medication is available in 480 mcg/0.8 mL. This indicates the concentration of filgrastim in the vial is 480 mcg per 0.8 mL.

5. We need to find the volume (mL) to administer that provides the daily dose (300 mcg) based on the medication concentration (480 mcg/0.8 mL).

Volume to administer (mL) = Daily dose (mcg) / Concentration (mcg/mL)

Volume to administer (mL) = 300 mcg / (480 mcg/0.8 mL)

To perform the division accurately, we need the concentration in the same units (mcg/mL) for both the numerator and denominator.

We can achieve this by multiplying the vial concentration (480 mcg/0.8 mL) by a factor that converts the denominator (0.8 mL) to 1 mL.

Factor = 1 mL / 0.8 mL = 1.25 (since 1.25 x 0.8 mL = 1 mL)

Apply the factor to adjust the concentration in the denominator:

Adjusted concentration = 480 mcg/0.8 mL * 1.25 = 600 mcg/mL

Now, calculate the volume to administer:

Volume to administer (mL) = 300 mcg / (600 mcg/mL)

Volume to administer (mL) = 0.5 mL (round to nearest tenth as requested)

Therefore, the nurse should administer approximately 0.5 mL of filgrastim subcutaneously.

Correct Answer is ["0.9"]

Explanation

Here's how to calculate the total volume the nurse should administer for the combined medication:

1. Calculate the volume of hydromorphone:

Dose: 4 mg

Concentration: 10 mg/mL (from ampule label)

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

Volume (mL) for hydromorphone = 4 mg / 10 mg/mL

Volume (mL) for hydromorphone = 0.4 mL

2. Calculate the volume of hydroxyzine:

Dose: 25 mg

Concentration: 50 mg/mL (from vial label)

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

Volume (mL) for hydroxyzine = 25 mg / 50 mg/mL

Volume (mL) for hydroxyzine = 0.5 mL

3. Add the volumes for each medication to find the total volume:

Total volume = Volume (mL) for hydromorphone + Volume (mL) for hydroxyzine

Total volume = 0.4 mL + 0.5 mL

Total volume = 0.9 mL (round to nearest tenth as requested)

Therefore, the nurse should administer a total of 0.9 mL.
