When the newborn's crib was moved suddenly, the nurse noticed that his legs flexed and the arms fanned out, and then both came back toward the midline. The nurse would interpret this behavior as:

Check for blood under the client's buttock. This is because lochia rubra is the normal vaginal discharge that occurs after childbirth, consisting of blood, mucus, and tissue from the placenta and the uterus lining. It is usually heavy for the first three to four days and can pool under the client's buttocks if they are lying down. Checking for blood under the buttock can help assess the amount of bleeding and prevent complications such as infection or hemorrhage.

The other choices are not correct for the following reasons:

A. Increasing the rate of the IV fluids is not necessary because the client's fundus is firm and midline, indicating that the uterus is contracting well and preventing excessive bleeding.

B. Assisting the client to ambulate is not advisable because it can increase the lochia flow and cause fainting or dizziness due to blood loss.

C. Performing fundal massage is not indicated because the fundus is already firm and midline, meaning that the uterus is adequately contracted. Massaging a firm fundus can cause pain and discomfort to the client.

Massage the fundus. This is because massaging the fundus (the upper part of the uterus) can help the uterus contract and prevent excessive bleeding after delivery. A soft, boggy uterus indicates uterine atony, which is a failure of the uterus to contract sufficiently after childbirth.

Uterine atony is the most common cause of postpartum hemorrhage, which can be life-threatening if not treated promptly¹².

Choice B is not correct because initiating measures that encourage voiding is not the appropriate intervention for a soft, boggy uterus. A full bladder can interfere with uterine contractions and cause bleeding, so it is important to empty the bladder after delivery. However, this should be done after massaging the fundus.

Choice C is not correct because positioning the patient flat is not the appropriate intervention for a soft, boggy uterus. Positioning the patient flat can increase blood loss and reduce venous return. The patient should be positioned with the head slightly elevated and the legs flexed to improve blood circulation and prevent shock³.

Choice D is not correct because notifying the doctor is not the first intervention for a soft, boggy uterus. Notifying the doctor is important if bleeding persists or worsens despite massaging the fundus. The doctor may order medications or other treatments to stop the bleeding and prevent complications¹.
