LEARNING OBJECTIVES


On completion of the materials in this chapter, you will be able to perform computations accurately by mastering the following mathematical concepts:



imageIn obstetric nursing, oxytocin (Pitocin) and magnesium sulfate are commonly used. Oxytocin is used to either augment or induce labor. Magnesium sulfate is used to prevent seizures in mothers diagnosed with preeclampsia and is also used “off label” to control preterm labor contractions. Both these medications can be titrated, which means that the medication can be adjusted up and down based on patient status.


IV ADMINISTRATION OF MEDICATIONS BY MILLIUNITS/MINUTE


EXAMPLE 1: The physician has ordered 1000 mL 5% dextrose in water (D5W) with 10 units IV oxytocin. Begin at 1 mU/min and then increase by 1 mU/min every 30 minutes until regular contractions occur. Maximum dose is 20 mU/min.
