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 ["75"]
Explanation
To answer this question, we need to find out how many mg of diphenhydramine are in one dose of 15 mL, and then multiply by the number of doses in a day. The bottle is labeled, diphenhydramine 12.5 mg/5 mL, which means that every 5 mL of liquid contains 12.5 mg of diphenhydramine. To find out how many mg of diphenhydramine are in one dose of 15 mL, we can use a proportion:
12.5 mg / 5 mL = x mg / 15 mL
Cross-multiplying and solving for x, we get:
x = (12.5 x 15) / 5
x = 37.5
Therefore, one dose of 15 mL contains 37.5 mg of diphenhydramine.
The prescription is for every 12 hours PRN, which means that the client can take up to two doses in a day as needed. The total daily dose in mg that the client receives is therefore:
37.5 x 2 = 75 mg
Correct Answer is ["8.3"]
Explanation
To calculate the duration of infusion, we need to divide the volume of fluid by the infusion rate. In this case, we have 500 mL of normal saline to be infused at 60 mL/hour. Therefore, the duration of infusion is 500 / 60 = 8.3333 hours.
Rounded off to the nearest tenth= 8.3 hours
