A client is receiving IV DSW at 125 mL per 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 per hour? (Enter numeric value only.)
The Correct Answer is ["440"]
While the primary infusion rate (dextrose 5% in water) and the total volume of pantoprazole solution are provided, the pantoprazole infusion doesn't directly affect the rate of the primary DSW infusion.
Here's the breakdown:
Primary Infusion:
Dextrose 5% in water (DSW) at 125 mL/hour (given) - This rate remains constant throughout the secondary infusion.
Secondary Infusion:
Pantoprazole 40 mg total dose (given)
Premixed solution volume: 110 mL (given)
Infusion duration: 15 minutes (given) = 0.25 hours (convert minutes to hours)
The nurse programs the secondary infusion pump to deliver the 110 mL pantoprazole solution over 0.25 hours, independent of the primary DSW infusion.
Therefore, the nurse should program the secondary infusion pump to deliver a rate of:
Delivery rate (mL/hour) = Total volume (mL) / Infusion time (hours)
Delivery rate (mL/hour) = 110 mL / 0.25 hours
Delivery rate (mL/hour) = 440 mL/hour (This is the rate for the pantoprazole solution only)
In conclusion:
The primary DSW infusion rate remains at 125 mL/hour.
The secondary pantoprazole infusion rate is 440 mL/hour, but it delivers the total dose (110 mL) over the 15-minute timeframe.

Correct Answer is ["0.7"]
Explanation
To find the volume of diphenhydramine the nurse should administer, we can divide the prescribed dose (mg) by the concentration (mg/mL) of the medication, and round to the nearest tenth:
1. Prescribed dose: 35 mg of diphenhydramine
2. Medication concentration: 50 mg/mL (milligrams of diphenhydramine per milliliter of solution)
3. Calculate the volume to administer:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
Volume (mL) = 35 mg / 50 mg/mL
Volume (mL) = 0.7 mL (round to the nearest tenth)
Therefore, the nurse should administer 0.7 mL of diphenhydramine.
Correct Answer is ["20"]
Explanation
1. Convert client weight to kilograms (kg):
Client weight (lbs) = 178
We know 1 kg = 2.2 lbs
Client weight (kg) = 178 lbs / 2.2 lbs/kg = 81.36 kg (rounded to two decimal places for accuracy)
2. Calculate the total diltiazem dosage:
Dosage per kg = 0.25 mg/kg
Client weight (kg) = 81.36 kg
Total dosage (mg) = Dosage per kg * Client weight (kg)
Total dosage (mg) = 0.25 mg/kg * 81.36 kg = 20.34 mg (rounded to two decimal places for accuracy)
3. Round the dosage to the nearest whole number for administration:
Total dosage (mg) = 20.34 mg (rounded to two decimal places)
In practice, medication dosages are typically rounded to the nearest whole number for safe and accurate administration. Therefore, the nurse should administer 20 mg of diltiazem.
