A nurse is collecting data from a postpartum client and notes the client's fundus is boggy and displaced to the right. Which of the following actions should the nurse take?

Choice B reason:
Uterine atony is the failure of the uterus to contract and retract after delivery, which can lead to excessive bleeding and hemorrhage. The client is at risk for uterine atony due to delivering a large newborn, which can overstretch the uterine muscles and reduce their tone.

Choice A reason:
Puerperal infection is an infection of the reproductive tract that occurs within six weeks after delivery. The client is not at increased risk for puerperal infection due to delivering a large newborn, unless there are other factors such as prolonged labor, multiple vaginal exams, or episiotomy.

Choice C reason:
Thrombophlebitis is an inflammation of a vein with a blood clot formation. The client is not at increased risk for thrombophlebitis due to delivering a large newborn, unless there are other factors such as immobility, dehydration, or trauma.

Choice D reason:
Retained placental fragments are pieces of the placenta that remain in the uterus after delivery, which can cause bleeding and infection. The client is not at increased risk for retained placental fragments due to delivering a large newborn, unless there are other factors such as abnormal placental atachment, manual removal, or incomplete separation.

Choice A reason: Position the client on her side is correct, as this is the first action the nurse should take according to the ABCDE priority framework. Late decelerations are symmetrical decreases in the fetal heart rate that begin after the peak of the contraction and return to baseline after the contraction ends, which indicate uteroplacental insufficiency and fetal hypoxia. Positioning the client on her side can improve blood flow and oxygen delivery to the placenta and fetus by relieving pressure on the vena cava and aorta.

Choice B reason: Elevate the client's legs is incorrect, as this is not a priority action for a client who has late decelerations. Elevating the legs can increase venous return and cardiac output, but it can also reduce blood flow and oxygen delivery to the placenta and fetus by compressing the vena cava and aorta.

Choice C reason: Administer oxygen via face mask is incorrect, as this is not the first action the nurse should take, although it is important to do later. Administering oxygen can increase oxygen saturation and delivery to the placenta and fetus, but it does not address the cause of uteroplacental insufficiency or improve blood flow.

Choice D reason: Increase the infusion rate of the IV fluid is incorrect, as this is not the first action the nurse should take, although it may be indicated later. Increasing the infusion rate of IV fluid can expand blood volume and improve placental perfusion, but it does not address the cause of uteroplacental insufficiency or improve blood flow. The nurse should obtain a provider's order before increasing the IV fluid rate.
