A client scheduled for coronary artery bypass surgery is to receive an intravenous infusion of 1 gram of cefazolin in 50 mL 0.9% Sodium Chloride, USP over 30 minutes. The nurse should program the infusion pump to deliver how many mL/hour?
(Enter numeric value only, as a whole number.)
The Correct Answer is ["100"]
Infusion rate (mL/hour) = Volume (mL) / Time (hour)
The nurse plugs in the values and gets:
Infusion rate (mL/hour) = 50 mL / 0.5 hour
Infusion rate (mL/hour) = 100 mL/hour
Therefore, the nurse should program the infusion pump to deliver 100 mL/hour of cefazolin solution to the client.

Correct Answer is ["83"]
Explanation
- Calculate the total volume of fluid to be infused: 2 liters = 2000 mL - Divide the total volume by the infusion time: 2000 mL / 24 hours = 83.33 mL/hour - Round to the nearest whole number: 83 mL/hour
- The infusion pump should be programmed to deliver 83 mL/hour of 5% DW
Correct Answer is ["0.5"]
Explanation
To calculate the correct dosage of streptomycin, the nurse needs to use the following formula:
D (desired dose) / H (have dose) x V (volume) = A (amount to administer)
In this case, the desired dose is 200 mg, the dose is 1000 mg (1 gram), and the volume is 2.5 mL. Plugging these values into the formula, we get:
200 / 1000 x 2.5 = 0.5
Therefore, the nurse should administer 0.5 mL of streptomycin every 12 hours.
