Order: 200 mL normal saline bolus IV over 15 minutes
On hand: 500 mL normal saline bags
What rate will the nurse set the pump to deliver the fluid?
The Correct Answer is ["800"]
This choice is correct because it is the result of dividing the volume of the bolus (200 mL) by the time of the infusion (15 minutes) and multiplying by 60 minutes per hour. The formula for calculating the rate of the pump is:
Rate = (Volume/Time) x 60
Therefore, the rate of the pump is:
Rate = (200 mL/ 15 min) x 60 = 800 mL/hr

Correct Answer is ["8"]
Explanation
To calculate the amount of belimumab that the nurse should administer, we can use the following steps:
Convert the patient's weight from pounds to kilograms.
Multiply the patient's weight in kilograms by the dosage of belimumab (10 mg/kg) to find the total dosage required.
Determine the volume of the drug needed using the concentration of the available belimumab solution.
Given:
Patient's weight = 136 lb
Dosage of belimumab = 10 mg/kg
Available concentration of belimumab = 80 mg/mL
Let's calculate step by step:
Convert patient's weight from pounds to kilograms:
Patient's weight in kg = 136 lb × (1 kg / 2.2 lb) ≈ 61.8 kg
Calculate the total dosage required:
Total dosage = 10 mg/kg × 61.8 kg ≈ 618 mg
Determine the volume of the drug needed using the concentration of the available belimumab solution:
Volume of drug = Total dosage / Concentration of belimumab
Volume of drug = 618 mg / 80 mg/mL ≈ 7.7 mL
Rounding to the nearest whole number, the nurse should administer 8 mL of the belimumab.
Correct Answer is ["2500"]
Explanation
The nurse needs to administer 2.5 L of 0.45% sodium chloride IV over 24 hours.
We know that 1 L is equal to 1000 mL.
So, 2.5 L is equal to 2.5 x 1000 mL/L = 2500 mL
Therefore, the nurse should administer 2500 mL over 24 hours.
