## 문제

A nurse is assessing a postpartum client 12 hours after vaginal delivery. Which assessment finding requires the nurse's immediate attention?

## 보기

1. Lochia rubra with small clots and mild cramping during breastfeeding
2. Fundus located 3 fingerbreadths above the umbilicus and displaced to the right **✔ 정답**
3. Perineal edema with intact sutures and no signs of hematoma formation
4. Breast engorgement with colostrum expression and mild tenderness

**정답: 2**

## 해설

A fundus 3 fingerbreadths above umbilicus and displaced right indicates uterine atony and bladder distention, requiring immediate intervention to prevent postpartum hemorrhage. Other findings are normal postpartum variations.

Clinical Reasoning and Priority Setting

The correct answer is option 2, as this assessment finding indicates a distended bladder that is displacing the uterus, which is the primary risk factor for uterine atony and subsequent postpartum hemorrhage (PPH).

Detailed Analysis of Findings

Why Option 2 Requires Immediate Attention

A fundus that is located 3 fingerbreadths above the umbilicus and displaced to the right is a classic clinical sign of a full bladder. A distended bladder mechanically pushes the uterus upward and laterally, preventing it from contracting effectively. The inability of the uterus to maintain firm contraction is the pathophysiological definition of uterine atony. Uterine atony is the most common cause of early postpartum hemorrhage, defined as cumulative blood loss exceeding 500 mL within the first 24 hours after vaginal delivery [1][2]. If the bladder is not emptied promptly, the relaxed uterus cannot compress the open vessels at the placental site, leading to rapid, potentially life-threatening blood loss. The structured clinical approach to PPH emphasizes that early recognition of such risk factors, like a displaced fundus, is critical to prevent progression to severe hypovolemia and organ dysfunction [2].

Why the Other Options Are Less Critical

- Option 1 (Lochia rubra with small clots and mild cramping): This is an expected finding at 12 hours postpartum. Lochia rubra is the normal vaginal discharge composed of blood and decidual debris. Small clots are common, and mild cramping during breastfeeding is a physiological response to endogenous oxytocin release, which promotes uterine involution. This does not indicate a complication.

- Option 3 (Perineal edema with intact sutures): Perineal edema is a common tissue response following vaginal delivery, especially if a laceration or episiotomy was repaired. The key reassuring signs here are intact sutures and the absence of a hematoma, which rules out a concealed hemorrhage in the perineal area. This requires comfort measures like ice packs but is not an emergency.

- Option 4 (Breast engorgement with colostrum expression): Mild breast engorgement and tenderness are normal physiological processes as milk production transitions from colostrum to mature milk. The ability to express colostrum indicates patent ducts. This requires supportive care and patient education on breastfeeding techniques but poses no immediate threat to maternal hemodynamic stability.

Pathophysiology and Clinical Integration

The primary mechanism linking a displaced fundus to a life-threatening emergency is the direct inhibition of myometrial contraction. After delivery of the placenta, hemostasis is achieved primarily through the contraction of the uterine muscle, which compresses the spiral arteries. A full bladder physically obstructs this process. The initial assessment of a postpartum patient always involves evaluating the fundus for its height, position, and consistency. A boggy or displaced uterus is the earliest warning sign of impending hemorrhage, and the first nursing intervention is always to assist the client to void. This aligns with the evidence-based principle that risk assessment and early identification of contributing factors, such as bladder distention, are fundamental to preventing PPH [1][2].References (research sources)

## 임상 시나리오

Clinical Practice Guide: Postpartum Fundal Assessment and Bladder Distention

**Key Clinical Alert:** A fundus palpated 3 fingerbreadths above the umbilicus and deviated to the right is a sentinel sign of a distended bladder. This mechanical displacement prevents the uterus from contracting firmly, directly precipitating uterine atony and placing the patient at high risk for early postpartum hemorrhage.

**Immediate Nursing Actions:**

- **Assist with Bladder Emptying:** The priority intervention is to assist the patient to void. Implement non-invasive measures first: provide privacy, run water, or use perineal warm water sprays. If unable to void within 15-30 minutes, perform a straight catheterization as ordered to relieve the distention.

- **Reassess Fundus Immediately:** After the bladder is emptied, immediately re-palpate the fundus. It should be firm, midline, and at or below the level of the umbilicus. If the fundus remains boggy or displaced, begin fundal massage and escalate care.

- **Monitor for Hemorrhage:** Concurrently assess lochia amount, vital signs, and signs of hypovolemia (tachycardia, hypotension, pallor). Quantify blood loss by weighing pads and noting saturation.

**Pathophysiology and Rationale:** A full bladder mechanically pushes the uterus superiorly and laterally. The over-distended uterine muscle cannot sustain a tetanic contraction, leaving the spiral arteries at the placental site open. This is the mechanism for atonic bleeding, the leading cause of PPH within the first 24 hours.

**Ongoing Management:** If fundal massage and bladder emptying do not restore tone, initiate the facility's PPH protocol. This includes administering uterotonic medications (e.g., oxytocin), establishing IV access, and preparing for potential bimanual compression or surgical intervention.

## 핵심 개념

- **Uterine Atony** — Loss of uterine muscle tone, the most common cause of early postpartum hemorrhage, preventing compression of placental site vessels.
- **Postpartum Hemorrhage (PPH)** — Cumulative blood loss exceeding 500 mL after vaginal delivery within the first 24 hours, often caused by uterine atony.
- **Fundal Displacement** — A uterus deviated laterally and elevated above the umbilicus, a classic sign of a distended bladder impeding uterine contraction.
- **Lochia Rubra** — Normal vaginal discharge in the first 3-4 days postpartum, consisting of blood, decidual tissue, and small clots.
