A patient is receiving a secondary infusion of azithromycin 500 mg in 500 mL of normal saline (NS) to be infused over 2 hours. How many mL/hour should the nurse program the infusion pump?
(Enter numerical value only.)
The Correct Answer is ["250"]
To find the answer, we can use the following formula:
(mL/hour) = (mL/minute) x 60
Substituting the given values, we get:
(mL/hour) = (500 / 120) x 60
Simplifying, we get:
(mL/hour) = 4.167 x 60
(mL/hour) = 250
Therefore, the nurse should program the infusion pump to deliver 250 mL/hour of azithromycin in NS to the patient.

Correct Answer is ["0.8"]
Explanation
To find the answer, we can use the following formula:
(mL to be administered) = (mg prescribed) / (mg per mL)
Substituting the given values, we get:
(mL to be administered) = (20) / (125 / 5)
Simplifying, we get:
(mL to be administered) = (20) x (5 / 125)
(mL to be administered) = 0.8
Therefore, the nurse should administer 0.8 mL of phenytoin suspension to the child.
Correct Answer is ["10"]
Explanation
To find the answer, we can use the following steps:
- Convert the child's weight from pounds to kilograms by dividing by 2.2
- Calculate the volume of amoxicillin suspension in mL by dividing the dose in mg by the concentration in mg/mL
- Round the result to the nearest whole number
Using these steps, we get:
- (weight in kg) = (88) / (2.2) = 40 kg
- (volume in mL) = (500) / (250 / 5) = 10 mL
- (rounded volume in mL) = 10 mL
Therefore, the nurse should administer 10 mL of amoxicillin suspension to the child.
