## 문제

A nurse is assessing a 61-year-old client with a history of hypertension who presents to the emergency department with shortness of breath. Which assessment finding would be most concerning and require immediate intervention?

## 보기

1. Blood pressure reading of 148/90 mmHg
2. Complaint of mild headache occurring in the morning
3. Patient reports taking antihypertensive medication irregularly
4. Sudden onset of severe chest pain with diaphoresis **✔ 정답**

**정답: 4**

## 해설

Sudden onset of severe chest pain with diaphoresis indicates a potential cardiac emergency like ACS, requiring immediate intervention. Other findings (elevated BP, mild headache, medication non-adherence) are less urgent and managed with routine care.

Correct Answer Analysis

The most concerning assessment finding requiring immediate intervention is sudden onset of severe chest pain with diaphoresis. In a 61-year-old client with hypertension presenting with shortness of breath, this combination of symptoms is a classic presentation of an acute coronary syndrome (ACS), specifically a possible myocardial infarction (MI), which represents an immediate threat to life.

Pathophysiology and Clinical Rationale

The client's underlying hypertension contributes to endothelial damage and accelerates atherosclerosis. When a coronary artery plaque ruptures, platelet aggregation and thrombus formation can abruptly occlude blood flow to the myocardium. The resulting myocardial ischemia manifests as severe chest pain. The accompanying diaphoresis is driven by sympathetic nervous system activation — a surge in catecholamines as the body responds to profound cardiac stress and compromised cardiac output. This sympathetic surge also increases myocardial oxygen demand, worsening the ischemia. If perfusion is not rapidly restored, myocardial necrosis, pump failure, and potentially fatal arrhythmias can develop.

The link to the presenting symptom of shortness of breath is critical. In the context of an acute MI, dyspnea can signal the rapid onset of acute pulmonary edema. As the left ventricle becomes ischemic and loses its ability to effectively pump blood forward, pressures rise backward into the left atrium and pulmonary vasculature. This increased hydrostatic pressure forces fluid from the pulmonary capillaries into the interstitial space and alveoli, impairing gas exchange. As highlighted in the reference material, acute pulmonary edema is a life-threatening condition that requires prompt intervention, and its development as a complication of an MI demands immediate recognition and management [1].

Why Other Options Are Less Immediate

| Option 1: Blood pressure reading of 148/90 mmHg | This reading indicates Stage 1 hypertension and is an expected finding in a client with a history of hypertension, especially when experiencing stress or pain. While it requires ongoing management, it does not represent an immediate, life-threatening crisis in the same way an acute MI does. |
| --- | --- |
| Option 2: Complaint of mild headache occurring in the morning | Morning headaches can be associated with poorly controlled hypertension, but a mild headache is a non-specific symptom. In the absence of signs of a hypertensive emergency (such as altered mental status or papilledema), this is a lower-priority concern compared to symptoms of active cardiac ischemia. |
| Option 3: Patient reports taking antihypertensive medication irregularly | Medication non-adherence is a significant finding that explains the likely chronic poor blood pressure control and is an important topic for patient education and discharge planning. However, it is a psychosocial and long-term management issue, not an acute physiological crisis requiring immediate intervention during the current emergency department visit. |

NCLEX-RN Clinical Judgment Focus

This question tests the ability to prioritize using the ABC (Airway, Breathing, Circulation) framework and to recognize a cluster of cues pointing to an emergent condition. The nurse must differentiate between a chronic disease exacerbation and an acute, life-threatening event. The sudden onset of severe chest pain with diaphoresis in a client with cardiovascular risk factors signals a potential acute MI, which can rapidly deteriorate into cardiogenic shock or acute pulmonary edema — a direct threat to both "Breathing" and "Circulation." The reference material reinforces that rapid identification of clinical changes and appropriate adjustment of interventions are critical skills in emergency medicine, as a change in condition with acute pulmonary edema demands prompt action [1].References (research sources)

## 임상 시나리오

Recognizing Acute Coronary SyndromeImmediate action for sudden chest pain with diaphoresis
In a client with hypertension and shortness of breath, the sudden onset of severe chest pain with diaphoresis is a classic presentation of Acute Coronary Syndrome (ACS), including possible myocardial infarction (MI). This is an immediate threat to life.

The diaphoresis is driven by sympathetic nervous system activation due to cardiac stress, which increases myocardial oxygen demand and worsens ischemia. The presenting dyspnea can signal developing acute pulmonary edema from left ventricular failure.

CautionPrioritize immediate 12-lead ECG acquisition and assessment over managing chronic issues like mild hypertension or medication history. Do not delay intervention to address non-emergent findings.

## 핵심 개념

- **Acute Coronary Syndrome (ACS)** — A spectrum of conditions involving acute myocardial ischemia or infarction, including unstable angina and myocardial infarction (MI), often presenting with chest pain.
- **Diaphoresis** — Profuse sweating, often a sign of sympathetic nervous system activation in response to severe stress, such as cardiac ischemia.
- **Myocardial Ischemia** — A condition where blood flow to the heart muscle is reduced, preventing it from receiving enough oxygen, typically due to a blockage in the coronary arteries.
- **Sympathetic Nervous System Activation** — The body's 'fight or flight' response, which in cardiac events releases catecholamines, increasing heart rate, contractility, and myocardial oxygen demand.
- **Pulmonary Edema** — A condition caused by excess fluid in the lungs, which can be a rapid complication of left ventricular failure during an MI, leading to severe shortness of breath.
