Question

What is the frequency of a 750 ml IV bag if the rate of infusion is 175 ml/hr? a) 5 hours

b) 4 hours and 18 minutes
c) 6 hours
d) 4 hours and 17 minutes

Answer 1

The frequency of a 750 ml IV bag with an infusion rate of 175 ml/hr is 4 hours and 17 minutes, as calculated by dividing the total volume by the rate and then converting the decimal hours to minutes. The Correct Answer is Option.D.

Step-by-step explanation:

The frequency of administration for a 750 ml IV bag at an infusion rate of 175 ml/hr can be calculated by dividing the total volume of the IV bag by the rate of infusion. In this case:

• Total IV bag volume = 750 ml
• Rate of infusion = 175 ml/hr

To find the time it takes to infuse the whole bag, we use the formula:

Time (hours) = Total Volume (ml) / Rate of Infusion (ml/hr)

Plugging in the values:

Time (hours) = 750 ml / 175 ml/hr = 4.2857 hours

Now, we convert the decimal part of the hours into minutes:

.2857 hours * 60 minutes/hour = 17.14 minutes ≈ 17 minutes

Therefore, the correct answer is 4 hours and 17 minutes, which corresponds to option d) 4 hours and 17 minutes.
