Question

Infuse NS 1000 ml, D5W 1000 ml, and LR 1000 ml, one bag after the other over 16 hours. What is the IV rate if the IV set delivers 20 gtts/ml? a) 20 drops per minute

b) 40 drops per minute
c) 50 drops per minute
d) 60 drops per minute

Answer 1

The IV rate for infusing 3000 ml over 16 hours using an IV set that delivers 20 drops/ml would be 60 drops per minute after calculating the hourly rate and converting it to a per minute rate. The Correct Answer is Option. D.

Step-by-step explanation:

To calculate the IV rate for the infusion of 3000 ml over 16 hours with an IV set that delivers 20 drops per milliliter (20 gtts/ml), you would first need to determine the total hourly rate, then convert this to a per minute rate, accounting for the specific drop factor of the IV set.

First, calculate the hourly rate:

1. 3000 ml for 16 hours means 3000 ml / 16 hours = 187.5 ml/hour.
2. To find the rate per minute, divide 187.5 ml/hour by 60 minutes/hour, which equals 3.125 ml/minute.
3. Since the IV set delivers 20 drops per ml, the final calculation is 3.125 ml/minute x 20 drops/ml = 62.5 drops per minute.

Since IV rates are typically rounded to the nearest whole number, the IV rate would be 60 drops per minute (choice d).
