A nurse is caring for a client who gave birth 2 hr ago.

The nurse notes that the client’s blood pressure is 60/50 mm Hg. What is the first action the nurse should take?

Choice A rationale
Vaginal bleeding during pregnancy can be a sign of a serious complication such as placenta previa or placental abruption. Placenta previa is a condition where the placenta partially or completely covers the cervix, which can lead to severe bleeding during pregnancy and delivery. Placental abruption is a serious condition in which the placenta separates from the uterus before the baby is born, which can cause heavy bleeding and can be life-threatening for both the mother and the baby. Therefore, any vaginal bleeding during pregnancy should be promptly reported to the healthcare provider.
Choice B rationale
Lightheadedness when lying on the back, also known as supine hypotensive syndrome, can occur in pregnancy when the enlarged uterus compresses the inferior vena cava, reducing blood return to the heart and causing a drop in blood pressure. While this can be uncomfortable, it is generally not considered a serious complication and can be alleviated by changing position.
Choice C rationale
Heartburn after eating is a common discomfort during pregnancy due to hormonal changes that relax the lower esophageal sphincter, allowing stomach acid to reflux into the esophagus. While it can be uncomfortable, it is generally not a sign of a serious complication.
Choice D rationale
Swelling of the ankles, also known as edema, is common in pregnancy due to increased fluid volume in the body. While it can be uncomfortable, it is generally not a sign of a serious complication unless it is sudden or severe, which could be a sign of preeclampsia.

Choice A rationale
Uterine atony refers to a soft and weak uterus after childbirth. It happens when your uterine muscles don’t contract enough to clamp the placental blood vessels shut after childbirth. This can lead to life-threatening blood loss after delivery. One of the causes of uterine atony is urinary retention. When the bladder is full, it can displace the uterus, preventing it from contracting properly. This can lead to uterine atony and postpartum hemorrhage. Therefore, urinary retention can cause uterine atony and lateral displacement of the fundus.
Choice B rationale
Poor involution of the uterus is a condition where the uterus does not return to its normal size after childbirth. While poor involution can lead to prolonged bleeding, it does not directly cause uterine atony. Uterine atony is specifically a lack of muscle contraction, while poor involution is a failure of the uterus to reduce in size.
Choice C rationale
While infection can lead to many complications during the postpartum period, it is not a direct cause of uterine atony. Infections can cause endometritis, which is inflammation of the uterine lining, but this does not prevent the uterus from contracting.
Choice D rationale
Hemorrhage, or heavy bleeding, is a result of uterine atony, not a cause. When the uterus does not contract properly after childbirth, it can lead to excessive bleeding, or hemorrhage.
