A client with a renal calculi receives a prescription for an intravenous infusion of 0.9% Sodium chloride Injection, USP 1,000 mL to be infused over 2.5 hours. The nurse should program the infusion pump to deliver how many mL/hour?
(Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["400"]
To calculate the infusion rate, we need to divide the total volume of fluid by the total time of infusion. In this case, we have 1,000 mL of 0.9% sodium chloride to be infused over 2.5 hours.
Therefore, the infusion rate is 1,000 / 2.5 = 400 mL/hour.

Correct Answer is ["0.7"]
Explanation
To answer this question, we need to convert the child's weight from pounds to kilograms, and then calculate the dose of filgrastim in mcg and mL for each day.
One pound is equal to 0.454 kg, so 88 pounds is equal to 88 x 0.454 = 39.952 kg.
The dose of filgrastim is 5 mcg/kg/day, so for a child who weighs 39.952 kg, the dose is 5 x 39.952 = 199.76 mcg/day.
The medication is labeled 300 mcg/mL, so to find the volume of medication in mL, we need to use a proportion: 300 mcg / 1 mL = 199.76 mcg / x mL
Cross-multiplying and solving for x, we get: x = (1 x 199.76) / 300
x = 0.66587 mL
This is the volume of medication that the nurse should administer daily to this child. Rounding to the nearest tenth, the answer is:
0.7 mL
The rationale for this answer is that we used the child's weight and the prescribed dose to find the amount of medication in mcg, and then used the concentration of the medication to find the volume in mL.
Correct Answer is ["0.5 "]
Explanation
To find the volume of each dose, we need to use a proportion based on the label of the vial. The label says that there are 1 gram of streptomycin in 2.5 mL of solution, so we can write this as 1 g / 2.5 mL = x g / y mL, where x is the amount of streptomycin in each dose and y is the volume of each dose. We know that x is 200 mg, which is equal to 0.2 g, so we can substitute this value in the equation and solve for y. We get:
1 g / 2.5 mL = 0.2 g / y mL
Cross-multiply and simplify:
y = (0.2 x 2.5) / 1
y = 0.5 mL
Therefore, the volume of each dose is 0.5 mL.
