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 ["2"]
Explanation
To calculate the amount of ampicillin the nurse should administer per dose in milliliters (mL) for a 500 mg IM dose, we can use the following steps:
Given:
Ampicillin dose: 500 mg
Available concentration after reconstitution: 250 mg/mL
Volume of sterile water to be added: 1.8 mL
Step 1: Calculate the amount of ampicillin to be administered per dose in mL
First, we need to reconstitute the ampicillin vial to yield the desired concentration of 250 mg/mL.
The concentration after reconstitution is 250 mg/mL, and the total dose required is 500 mg. Therefore, the nurse needs to administer:
Volume = Ampicillin dose / Concentration
Volume = 500 mg / 250 mg/mL
Volume = 2 mL
Rounding to the nearest whole number:
Volume = 2 mL
Therefore, the nurse should administer 2 mL of the reconstituted ampicillin solution per dose.
Correct Answer is ["10"]
Explanation
The nurse needs to administer 775 mg of amoxicillin. The available amoxicillin oral suspension is 400 mg/5 mL, which means there are 400 mg of amoxicillin in every 5 mL of the suspension.
Therefore, for a 775 mg dose, the nurse should administer:
775 mg/(400 mg/5mL) = 9.6875 mL of the suspension
So, the nurse should administer approximately 10 mL (rounded to the nearest whole number).
