A nurse is assessing a client who is 2 days postpartum and is breastfeeding.

The nurse notes that the fundus is two centimeters below the umbilicus, lochia rubra is scant, and the breasts are warm to touch.

Which of the following interpretations of these findings should the nurse make?

Choice A rationale

Afterpains are intermittent uterine contractions that occur during involution. Breastfeeding stimulates the release of oxytocin, a potent uterotonic hormone, which intensifies these contractions. Therefore, a bottle-feeding woman would be less likely to experience strong afterpains compared to a breastfeeding woman.

Choice B rationale

Oligohydramnios is a condition of low amniotic fluid. Uterine distention is the primary cause of strong afterpains. Since oligohydramnios results in a smaller-than-average uterus, the associated afterpains are typically less intense because the uterus was not excessively stretched during the pregnancy.

Choice C rationale

A newborn weighing 5 pounds, 3 ounces (2353 grams) is considered low birth weight, suggesting the uterus was less distended than in a pregnancy with a larger infant. Afterpains are more severe in conditions causing overdistention, such as macrosomia, where the stretched muscle fibers have a greater distance to retract.

Choice D rationale

Multiple gestation, such as twins, causes excessive stretching and overdistention of the uterine muscle fibers due to the presence of two fetuses and placentas. The more the uterus is stretched, the harder it must contract to return to its pre-pregnancy size, resulting in stronger and more uncomfortable afterpains.

Choice D rationale

. Severe, unrelenting perineal pain that is disproportionate to the typical discomfort and is not relieved by standard analgesia 24 hours postpartum, despite stable vital signs and a firm uterus, strongly suggests the presence of a perineal or vulvar hematoma. A hematoma is a collection of blood in the connective tissue, which causes intense pressure and pain. The nurse must inspect the perineum and vulva for signs of swelling, discoloration, or a mass to confirm this diagnosis, which may require surgical drainage for definitive treatment.

Choice A rationale

. Reassessing the fundus is a routine postpartum check, as a boggy uterus is the primary cause of early postpartum hemorrhage. However, the question states the uterus is already firm and midline, which rules out uterine atony as the cause of the severe pain. Repeating this assessment would be redundant and would delay the necessary focused assessment of the perineum for other causes of pain.

Choice B rationale

. Oxytocin (Pitocin) is administered to promote uterine contraction and involution, thus preventing postpartum hemorrhage due to atony. Since the client's uterus is reported as firm and midline, there is no indication for the administration or reassessment of the need for Oxytocin. The severe pain is likely a local issue in the perineum, not a systemic or uterine issue requiring uterotonic medication.

Choice C rationale

. Assessing the client's temperature is a general vital sign check for infection, such as endometritis or a wound infection. While infection can cause pain, severe, disproportionate, unremitting pain in the first 24 hours, unrelieved by medication, is more characteristic of internal pressure from a hematoma than an infection, which typically manifests with fever and localized redness or discharge later on.
