At what rate should 1000 ml of Ringer's lactate be administered over 8 hours?

To determine the correct rate for administering 1000 ml of Ringer's lactate over an 8-hour period, you can use the formula:

Rate (ml/h) = Total volume (ml) / Time (h)

In this case, the total volume is 1000 ml, and the time is 8 hours.

When you perform the calculation:

Rate = 1000 ml / 8 h = 125 ml/h

This calculation indicates that the correct rate of administration should be 125 ml per hour, which matches the answer identified. Administering at this rate would ensure that the full volume is delivered within the allotted time frame, providing optimal fluid therapy. Understanding the importance of correct fluid administration rates is vital in midwifery and obstetrics, as it ensures patient safety and effective management of fluid balance.
