A nurse prepares 410. of an IV of normal saline solution to be delivered at a rate of 85mL / h What is the infusion time, in hours, to deliver 410. Express your answer to significant figures and include the appropriate units
To determine the infusion time, we will divide the volume of fluid (410 mL) by the rate of infusion (85 mL/h):
410 mL / 85 mL/h = 4.82 h
To express the answer to the correct number of significant figures, we round to the nearest hundredth:
4.82 h (to two decimal places)
Therefore, the infusion time is 4.82 hours.
To determine the infusion time, we can use the formula:
Infusion time = Volume / Rate
Given:
Volume = 410 mL
Rate = 85 mL/h
Using the formula, substitute the values:
Infusion time = 410 mL / 85 mL/h
Calculating:
Infusion time = 4.823529411764706 hours
Rounded to the appropriate significant figures, the infusion time is approximately 4.82 hours.
To find the infusion time, we need to divide the total volume of the IV solution (410 mL) by the rate at which it is being delivered (85 mL/h).
Infusion time = Total volume / Infusion rate
Substituting the values:
Infusion time = 410 mL / 85 mL/h
To express the answer to the correct number of significant figures, we will use three significant figures, as indicated by the given values.
Calculating the infusion time:
Infusion time = 4.82 hours
Therefore, the infusion time to deliver 410 mL of IV solution at a rate of 85 mL/h is approximately 4.82 hours.
