## 문제

The nurse is evaluating a client and determines that which of these findings requires the most urgent notification to the HCP?

## 보기

1. Complaint of mild back pain rated 4/10
2. Blood pressure of 150/90 mmHg
3. Sudden onset of severe abdominal pain with hypotension **✔ 정답**
4. Pulsatile abdominal mass palpated during assessment

**정답: 3**

## 해설

Sudden severe abdominal pain with hypotension indicates potential AAA rupture, a life-threatening emergency. Other findings are less urgent in this context.

Clinical Reasoning and Prioritization

The finding that requires the most urgent notification to the healthcare provider (HCP) is sudden onset of severe abdominal pain with hypotension. This combination represents a classic presentation of a life-threatening intra-abdominal emergency, most notably a ruptured abdominal aortic aneurysm (AAA), which demands immediate surgical intervention.

Pathophysiology and Clinical Significance

A sudden onset of severe abdominal pain coupled with hypotension indicates a catastrophic event where the integrity of a major vessel or organ has been compromised, leading to rapid blood loss and hemodynamic instability. In the context of a pulsatile abdominal mass, this presentation is pathognomonic for a ruptured AAA. The rupture leads to a sudden extravasation of blood into the retroperitoneal space, causing a sharp drop in intravascular volume and systemic blood pressure. The body's compensatory mechanisms, such as tachycardia and vasoconstriction, are often insufficient to maintain perfusion, leading to a state of hypovolemic shock. The 2025 Korean CPR Guidelines explicitly identify shock as a priority emergency requiring immediate prehospital and in-hospital intervention . The clinical triad of hypotension, severe acute pain, and a pulsatile mass is a surgical red flag. As noted in the trauma literature, traditional indicators for immediate laparotomy without delay for preoperative imaging include hemodynamic instability, which is precisely what the hypotension signifies in this scenario . Delaying notification to obtain further diagnostics like a CT scan in an unstable patient can be detrimental, as the priority is immediate hemorrhage control in the operating room .

Analysis of Other Options

- Complaint of mild back pain rated 4/10: While back pain can be associated with an AAA, the pain's mild and non-severe nature, without accompanying hemodynamic changes, makes it a less urgent finding. It requires further investigation but does not signal an immediate, life-threatening rupture.

- Blood pressure of 150/90 mmHg: This finding represents hypertension and requires follow-up and management to prevent long-term complications. However, it does not pose an immediate threat of death within minutes to hours like acute hemorrhagic shock does. It is a chronic management issue, not an acute surgical emergency.

- Pulsatile abdominal mass palpated during assessment: This is a critical incidental finding highly suggestive of an abdominal aortic aneurysm. It requires prompt and thorough evaluation, including imaging and surgical consultation. However, in a stable patient without pain or hypotension, the aneurysm is contained. The immediate threat is rupture, which has not yet occurred. The sudden onset of pain and hypotension signals that the contained mass has now ruptured, making that combination the most urgent finding. The urgency of a pulsatile mass alone is high but does not surpass an active, ongoing hemorrhage.

Clinical Decision-Making and Immediate Nursing Action

The nurse’s immediate priority is to recognize this as a surgical emergency. The patient is in a state of decompensated shock. The primary intervention is to notify the HCP immediately while simultaneously initiating supportive measures: establishing two large-bore intravenous lines, administering high-flow oxygen, and preparing for rapid volume resuscitation and possible blood transfusion. The goal is to stabilize the patient for emergent transport to the operating room. The principle of early prediction of surgical necessity in gastrointestinal emergencies is critical to avoid delayed intervention and improve patient outcomes, and this clinical picture is a definitive indicator for surgery .

## 임상 시나리오

Ruptured AAA: Immediate RecognitionTriad of hypotension, severe pain, and pulsatile mass
A sudden onset of severe abdominal or back pain with hypotension is a surgical emergency, most commonly indicating a ruptured abdominal aortic aneurysm (AAA). This represents active hemorrhagic shock from blood loss into the retroperitoneal space.

The classic clinical triad is hypotension, severe acute pain, and a pulsatile abdominal mass. The presence of hypotension signifies hemodynamic instability and a high risk of imminent cardiovascular collapse. Immediate notification of the HCP and surgical team is the highest priority.

CautionDo not delay notification for imaging if the patient is hemodynamically unstable. Palpation of the mass should be gentle to avoid dislodging clot. Prepare for massive transfusion protocol and immediate surgical intervention.

## 핵심 개념

- **Ruptured Abdominal Aortic Aneurysm (AAA)** — A life-threatening condition where a weakened area of the abdominal aorta tears, causing massive internal bleeding, often presenting with the triad of hypotension, severe pain, and a pulsatile mass.
- **Hypovolemic Shock** — An emergency condition in which severe blood loss leads to inadequate oxygen delivery to tissues, characterized by hypotension, tachycardia, and altered mental status.
- **Hemodynamic Instability** — A state of abnormal or unstable blood pressure and perfusion, often indicating a critical failure of the circulatory system requiring immediate intervention.
- **Retroperitoneal Space** — The anatomical space in the abdominal cavity behind the peritoneum where the aorta lies; bleeding from a ruptured AAA often occurs here, causing severe pain.
- **Pathognomonic** — A sign or symptom that is so characteristic of a disease that it can be used to make a diagnosis, such as the triad for a ruptured AAA.
