A client who is scheduled for induction of labor receives a prescription for oxytocin 2 milliunits/min intravenously (IV). The IV bag contains oxytocin 20 units in lactated Ringer’s 1 liter.
How many mL/hour should the nurse program the infusion pump to deliver? .
The Correct Answer is ["6"]
The correct answer is calculated as follows:
Step 1: Identify the total amount of oxytocin in the IV bag. The bag contains 20 units of oxytocin in 1 liter (or 1000 mL) of lactated Ringer’s solution.
Step 2: Convert the oxytocin units to milliunits. 1 unit = 1000 milliunits, so 20 units = 20,000 milliunits.
Step 3: Calculate the concentration of the oxytocin solution in milliunits/mL. Divide the total amount of oxytocin in milliunits by the total volume of the solution in mL.
So, 20,000 milliunits ÷ 1000 mL = 20 milliunits/mL.
Step 4: Calculate the infusion rate in mL/hour. The prescription is for an infusion rate of 2 milliunits/min. Since the concentration of the solution is 20 milliunits/mL, we divide the prescribed rate by the concentration to get the rate in mL/min. So, 2 milliunits/min ÷ 20 milliunits/mL = 0.1 mL/min.
Step 5: Convert the infusion rate to mL/hour. Multiply the rate in mL/min by the number of minutes in an hour. So, 0.1 mL/min × 60 min/hour = 6 mL/hour. Therefore, the nurse should program the infusion pump to deliver 6 mL/hour.

Correct Answer is D
Explanation
Choice A rationale
Avoiding caffeinated drinks for 24 hours before conducting the kick test is not necessary. Caffeine does not significantly affect fetal movements.
Choice B rationale
Exercising for 15 minutes before starting the counting to help increase fetal movement is not a standard recommendation. While physical activity can sometimes stimulate fetal movement, it’s not a requirement for performing kick counts.
Choice C rationale
Counting the movements once daily, for one hour, before breakfast is not the standard recommendation. The best time to do kick counts is when the baby is usually most active, which might be after a meal, early in the morning, or at another point in the day.
Choice D rationale
If 10 kicks are not felt within one hour, drinking orange juice and counting for another hour is a common recommendation. The sugar in the juice can sometimes stimulate the baby to move. However, if the mother still doesn’t feel 10 movements within 2 hours, she should contact her healthcare provider.
Correct Answer is D
Explanation
Choice A rationale
While monitoring the client’s vital signs is an important part of postpartum care, it would not directly address the issue of a boggy uterus that is displaced above and to the right of the umbilicus.
Choice B rationale
Notifying the healthcare provider is important, but it would not be the first action to take. The nurse should first attempt to address the issue.
Choice C rationale
Inspecting the perineal pad could provide information about the client’s postpartum bleeding, but it would not directly address the issue of a boggy uterus that is displaced above and to the right of the umbilicus.
Choice D rationale
Encouraging the client to void is the correct action. A full bladder can displace the uterus, preventing it from contracting properly. By emptying the bladder, the uterus may be able to contract and return to its normal position.
