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 ["0.7"]

Explanation

The nurse should administer 0.7 mL of diphenhydramine.

Here's the calculation:

Medication dosage: 35 mg (diphenhydramine)

Medication concentration: 50 mg/mL (given on the syringe label)

We need to find the volume (mL) containing the prescribed dose (35 mg) of diphenhydramine.

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

Volume to administer (mL) = 35 mg / 50 mg/mL

Volume to administer (mL) = 0.7 mL (round to nearest tenth)

Therefore, the nurse should administer 0.7 mL of diphenhydramine

Correct Answer is ["2.4"]

Explanation

Here's how to calculate the volume (mL) the nurse should administer for cefazolin:

1. We know the following:

Prescribed dose: 800 mg cefazolin IM every 6 hours (given)

Vial content: 1 gram cefazolin (given)

However, we need to consider the reconstitution process for accurate dosage calculation.

Reconstitution information:

For IM use, add 2.5 mL sterile water for injection.

This dilution creates a total volume of 3.0 mL.

3. We need to find the concentration of cefazolin in the reconstituted solution (mg/mL).

Concentration (mg/mL) = Total drug amount (mg) / Total volume (mL) after reconstitution

Concentration (mg/mL) = 1 gram (which is 1000 mg) / 3.0 mL

Concentration (mg/mL) = 333.33 mg/mL (round to nearest tenth)

4. Now, we can find the volume to administer for the prescribed dose (800 mg) considering the concentration (333.33 mg/mL) in the reconstituted solution.

Volume to administer (mL): Dose (mg) / Concentration (mg/mL)

Volume to administer (mL): 800 mg / 333.33 mg/mL

Volume to administer (mL): 2.40 mL (round to nearest tenth)

Therefore, the nurse should administer approximately 2.4 mL of the reconstituted cefazolin solution intramuscularly.
