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 B
Explanation
Choice A rationale
While hard, painful uterine afterpains can be uncomfortable for the patient, they are a normal part of the postpartum period and are not typically a priority complication following a severe postpartum hemorrhage16.
Choice B rationale
Disseminated intravascular coagulation (DIC) is a serious condition that can occur as a complication of severe postpartum hemorrhage. It involves an overactive clotting process leading to the formation of small blood clots that can block blood vessels and cause significant organ damage16.
Choice C rationale
Postpartum psychosis is a serious mental health disorder that can occur after childbirth. However, it is not directly related to postpartum hemorrhage and would not typically be the priority complication in this scenario16.
Choice D rationale
Placenta accreta is a condition where the placenta grows too deeply into the uterine wall. While it can cause severe bleeding after delivery, it would not typically be a priority complication to assess for following a severe postpartum hemorrhage16.
Correct Answer is A
Explanation
Choice A rationale
Iron-deficiency anemia is a common nutritional issue among pregnant teenagers. During pregnancy, the body needs more iron to support the growth and development of the fetus. Teenagers, who are still growing themselves, may already have lower iron stores. Therefore, it is crucial to include information about the importance of iron and how to get enough from the diet in a nutrition education program for pregnant teenagers.
Choice B rationale
While gestational diabetes is a concern during pregnancy, it is not the most crucial topic for a nutrition education program specifically for pregnant teenagers. Gestational diabetes is a condition that can develop during pregnancy in women who don’t already have diabetes. It’s not as common in teenagers as it is in older women.
Choice C rationale
High cholesterol is generally not a primary concern during pregnancy. In fact, it’s normal for cholesterol levels to rise during pregnancy. However, long-term high cholesterol can increase the risk of heart disease.
Choice D rationale
Excessive weight gain can be a concern during pregnancy, but it is not the most crucial topic for a nutrition education program for pregnant teenagers. It’s normal and healthy to gain weight during pregnancy, but the amount should be carefully monitored. Excessive weight gain can lead to complications such as gestational diabetes or high blood pressure.
