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 ["2"]
Explanation
The correct answer is 2 ounces. To find the answer, we can use the following steps:
- Calculate the volume of magnesium hydroxide in mL by dividing the dose in mg by the concentration in mg/mL
- Convert the volume in mL to ounces by multiplying by 0.0338
- Round the result to the nearest whole number
Using these steps, we get:
- (volume in mL) = (4800) / (400) = 12 mL
- (volume in ounces) = (12) x (0.0338) = 0.4056 ounces
- (rounded volume in ounces) = 2 ounces
Therefore, the nurse should instruct the client to take 2 ounces of magnesium hydroxide Saline Laxative, USP with each dose.
Correct Answer is ["333"]
Explanation
To find the answer, we can use the following formula:
(mg/mL) = (mg of cefazolin) / (mL of solution)
Substituting the given values, we get:
(mg/mL) = (1000) / (3)
Simplifying, we get:
(mg/mL) = 333.333
(rounded mg/mL) = 333
Therefore, after reconstitution, the solution contains 333 mg/mL of cefazolin.
