Final answer:
The correct IV pump rate to administer 1500 ml of NS over 8 hours is 187.5 ml/hr. However, rounding to the nearest whole number provides 188 ml/hr, which is not listed among the answer choices, indicating a potential error in the provided options.
Step-by-step explanation:
The student is asking how to calculate the rate at which an intravenous (IV) pump should be set to administer a certain volume of fluid over a specified period. To solve this, we divide the total volume of fluid (1500 ml) by the total time (8 hours).
To calculate:
Rate (ml/hr) = Total Volume (ml) / Total Time (hr)
Rate (ml/hr) = 1500 ml / 8 hr
Therefore, the rate is 187.5 ml/hr. Since this is not an option provided, rounding to the nearest whole number gives 188 ml/hr, which is not one of the answer choices. It seems there may be an error in the provided options, as none of them reflect the correct calculation.
