## 문제

A 35-year-old gravida 4, para 3 client at 32 weeks gestation presents to the emergency department with sudden onset of severe abdominal pain and vaginal bleeding. Assessment reveals a rigid, board-like abdomen, fetal heart rate of 90 bpm with minimal variability, and maternal vital signs: BP 90/60 mmHg, HR 120 bpm, RR 24/min. Abruptio placentae is suspected. What is the priority nursing intervention?

The client appears anxious and states, "Something is terribly wrong with my baby." The physician has been notified and is en route to the unit.

## 보기

1. Administer oxygen via nasal cannula at 2-4 L/min
2. Insert two large-bore IV catheters and initiate fluid resuscitation
3. Position the client in left lateral position to improve placental perfusion
4. Prepare for immediate cesarean delivery and notify the operating room **✔ 정답**

**정답: 4**

## 해설

Immediate cesarean delivery is the priority due to fetal compromise (heart rate 90 bpm) and maternal hemorrhage (hypotension, tachycardia), which indicate life-threatening abruptio placentae. Other interventions are supportive but secondary to urgent delivery.

Clinical Presentation Analysis

The client presents with classic signs of severe abruptio placentae: sudden severe abdominal pain, vaginal bleeding, and a rigid, board-like abdomen indicating significant concealed hemorrhage and uterine hypertonus. The fetal heart rate of 90 bpm with minimal variability reflects severe fetal distress and hypoxia. Maternal vital signs—BP 90/60 mmHg and HR 120 bpm—demonstrate hypovolemic shock from blood loss. This combination of maternal hemodynamic instability and a non-reassuring fetal status signals a catastrophic disruption of the placental-uterine interface [1].

Pathophysiology and Clinical Rationale

In placental abruption, premature separation of the placenta from the uterine wall compromises the maternal-fetal exchange surface. The resulting retroplacental hemorrhage can be concealed, leading to a rigid, painful uterus as blood infiltrates the myometrium. Fetal oxygenation becomes critically impaired, manifesting as bradycardia and loss of variability. Simultaneously, maternal blood loss—often underestimated externally—triggers compensatory tachycardia and hypotension. The clinical challenge, as noted in the evidence, is that profound bleeding necessitates urgent delivery when there is concern for maternal and fetal compromise [1]. The definitive treatment for severe abruption with a viable fetus in distress is immediate delivery, because the underlying pathology—placental separation—cannot be reversed; delivery removes the fetus from the hypoxic environment and controls the source of maternal hemorrhage.

Priority Intervention Analysis

The question asks for the priority nursing intervention using a framework that addresses the root cause of both maternal and fetal instability. While all listed interventions are appropriate in the management of abruptio placentae, the sequencing must reflect the definitive solution.

- Option 1 (Administer oxygen): Oxygen supplementation improves maternal oxygen saturation but does not correct the primary problem of disrupted placental perfusion. It is a supportive measure, not the definitive priority when delivery is indicated.

- Option 2 (Insert IV and fluid resuscitation): Fluid resuscitation is critical for managing maternal hypovolemic shock. However, in the context of ongoing severe hemorrhage from an abruption, volume replacement is a temporizing measure that bridges to definitive surgical control. It is a simultaneous priority but not the overriding one that resolves the crisis.

- Option 3 (Left lateral position): Positioning the client in left lateral tilt reduces aortocaval compression and can transiently improve uteroplacental blood flow. In a mild abruption with a reassuring fetal status, this might be an early intervention. Here, with a rigid uterus, profound fetal bradycardia, and maternal shock, repositioning will not halt the ongoing separation or control hemorrhage.

- Option 4 (Prepare for immediate cesarean delivery): This is the priority because it directly addresses the underlying pathology. The evidence states that clinical challenges arise with profound bleeding, necessitating urgent delivery when there is concern for maternal and fetal compromise [1]. Preparing the operating room and team mobilizes the definitive treatment that simultaneously stops maternal hemorrhage and delivers the compromised fetus. All other interventions (oxygen, IV access, positioning) are performed concurrently while preparing for the cesarean section, but the act of preparation and notification is the nurse's pivotal coordinating action that drives the team toward the only definitive solution.References (research sources)

## 임상 시나리오

Clinical Practice Guide: Severe Abruptio Placentae

When a client presents with a rigid, board-like abdomen, vaginal bleeding, maternal hypotension, and fetal bradycardia, suspect a severe placental abruption with concealed hemorrhage. The immediate priority is to prepare for emergency cesarean delivery, as this is the only definitive treatment to stop the hemorrhage and resolve fetal distress.

**Key Actions:**

- **Activate the surgical team immediately:** Notify the operating room, anesthesia, and neonatology staff. Do not delay for additional diagnostics if the clinical picture is clear.

- **Initiate supportive measures concurrently:** While awaiting surgery, insert two large-bore IV lines and begin fluid resuscitation with crystalloids or blood products as ordered. Apply oxygen via a non-rebreather mask to maximize maternal and fetal oxygenation.

- **Position for maternal perfusion:** Place the client in a left lateral position to reduce aortocaval compression, but recognize this is a temporizing measure, not a substitute for delivery.

- **Monitor continuously:** Assess maternal vital signs, fetal heart rate, and uterine tone every 5-15 minutes. Document blood loss and watch for signs of disseminated intravascular coagulation (DIC), a common complication.

**Nursing Consideration:** Address the client's anxiety by explaining interventions calmly and providing reassurance that the team is acting quickly to protect both her and her baby. Keep the support person informed without delaying critical tasks.

## 핵심 개념

- **Abruptio Placentae** — Premature separation of the placenta from the uterine wall, causing hemorrhage, uterine hypertonus, and impaired fetal oxygenation.
- **Concealed Hemorrhage** — Bleeding that is trapped behind the placenta and not visible externally, leading to a rigid, board-like abdomen and underestimated blood loss.
- **Fetal Bradycardia** — A fetal heart rate below 110 bpm, indicating fetal distress and hypoxia, often requiring immediate intervention.
- **Hypovolemic Shock** — A life-threatening condition caused by significant blood or fluid loss, leading to tachycardia, hypotension, and inadequate tissue perfusion.
- **Uterine Hypertonus** — A state of increased resting tone of the uterus, commonly seen in abruptio placentae, which contributes to pain and fetal compromise.
