A nurse is assessing a postpartum client 24 hours after vaginal delivery. Which assessment finding would be considered normal for this time period?
1Fundus firm and located at the umbilicus✓ 정답
2Lochia rubra with large clots and heavy flow
3Blood pressure 160/100 mmHg

At 24 hours postpartum, a firm fundus at the umbilicus is normal for uterine involution. Lochia rubra with large clots, elevated BP, or fever indicate complications requiring intervention.
Understanding Normal Postpartum Involution at 24 Hours
At 24 hours postpartum, the nurse's assessment focuses on the physiological process of uterine involution and the return of other body systems to a pre-pregnancy state. Understanding the normal trajectory for each parameter is critical for distinguishing expected recovery from early signs of complications like postpartum hemorrhage or infection.
Analysis of the Correct Answer
Fundus firm and located at the umbilicus is the expected normal finding. Immediately after delivery, the uterine fundus is typically palpable midway between the symphysis pubis and the umbilicus. Over the first 24 hours, it rises to the level of the umbilicus as the pelvic floor muscles and ligaments regain tone. A firm consistency, often described as "well-contracted," indicates effective myometrial contraction, which compresses open blood vessels at the placental site. This physiological mechanism is the primary defense against postpartum hemorrhage (PPH). The clinical guideline for postpartum care emphasizes that a well-contracted uterus is a cornerstone of normal involution . Research on interventions to enhance involution further confirms that poor uterine contraction is a direct cause of short-term poor involution and a significant risk factor for PPH [2].
Analysis of Incorrect Answers
Lochia rubra with large clots and heavy flow is an abnormal finding. While lochia rubra, the red, blood-tinged discharge, is expected for the first 2-3 days, the flow should be moderate and free of large clots. The presence of large clots and heavy flow suggests uterine atony or retained placental fragments, conditions that prevent the uterus from contracting effectively. Studies on prophylactic techniques for PPH highlight that uncontrolled bleeding from an atonic uterus can rapidly become life-threatening, requiring immediate intervention such as uterine compression sutures [3]. A comparative clinical study on PPH prevention reinforces that monitoring lochia volume and character is essential for early detection of excessive bleeding .
Blood pressure 160/100 mmHg is a critical abnormal finding. While some fluid shifts occur postpartum, a blood pressure this elevated is a hallmark of postpartum preeclampsia. This condition can develop up to six weeks after delivery and requires urgent medical management to prevent eclampsia, stroke, and other end-organ damage. The postpartum clinical guideline includes the monitoring of vital signs to detect such hypertensive disorders, which are a leading cause of postpartum maternal morbidity .
Temperature 101.5°F (38.6°C) is a significant deviation from normal. A low-grade temperature elevation can occur in the first 24 hours due to dehydration and the exertion of labor. However, a temperature of 101.5°F (38.6°C) is a strong indicator of infection, most commonly postpartum endometritis. Other sources of infection, such as wound infection, mastitis, or urinary tract infection, must also be investigated. The clinical guideline for postpartum care identifies fever as a key warning sign that necessitates a thorough evaluation for infectious causes .

Clinical Practice Guide: Postpartum Fundal Assessment at 24 Hours
Expected Findings
Fundal Position: The uterine fundus should be located at the level of the umbilicus. It rises to this level during the first 24 hours postpartum.
Fundal Consistency: The fundus must feel firm and well-contracted upon palpation. A boggy or soft uterus requires immediate massage to stimulate contraction and prevent hemorrhage.
Lochia: Lochia rubra is expected, with a moderate flow. The amount should be assessed by pad saturation, with no large clots present.
Nursing Actions
Assist the client into a supine position with knees slightly flexed to relax abdominal muscles.
Using the side of one hand, palpate the abdomen gently but firmly from the umbilicus downward to locate the fundus.
If the fundus is displaced to the right, assist the client to void, as a full bladder can inhibit uterine contraction and elevate the fundus above the umbilicus.
If the fundus is boggy, gently massage it in a circular motion until it becomes firm, then express any clots from the lower uterine segment.
Document fundal height in relation to the umbilicus (e.g., U/U for firm at umbilicus, U-1 for one fingerbreadth below), consistency, and lochia characteristics.
Critical Alerts
Postpartum Hemorrhage: A boggy fundus, heavy lochia with large clots, and fundal height above the umbilicus are classic signs of uterine atony, the leading cause of PPH.
Preeclampsia: Routine vital sign monitoring is essential; a blood pressure of 160/100 mmHg or higher is a hypertensive emergency requiring immediate escalation.
Infection: A temperature of 100.4°F (38°C) or higher after the first 24 hours, especially with foul-smelling lochia, suggests endometritis and requires evaluation.
Involution — The process by which the uterus returns to its pre-pregnancy size and condition, involving contraction of myometrial muscles and autolysis of cells.
Fundus — The upper, rounded portion of the uterus; its position and firmness are key indicators of postpartum uterine contraction.
Lochia Rubra — The initial vaginal discharge after delivery, consisting of blood and decidual debris, which is typically red and lasts for the first 2-3 days.
