Final answer:
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.
