## 문제

A 62-year-old patient presents to the emergency department with a blood pressure of 180/110 mmHg, severe headache, and nausea. The patient reports chest pain and shortness of breath. Which nursing action should be the immediate priority?

## 보기

1. Initiate continuous cardiac monitoring and prepare for antihypertensive therapy **✔ 정답**
2. Administer sublingual nitroglycerin to reduce blood pressure quickly
3. Position the patient in Trendelenburg position to improve cerebral perfusion
4. Encourage the patient to perform deep breathing exercises to reduce anxiety

**정답: 1**

## 해설

Hypertensive crisis with target organ damage requires immediate, controlled blood pressure reduction with continuous monitoring to prevent complications like stroke or MI. Sublingual nitroglycerin is not first-line, Trendelenburg position is contraindicated, and deep breathing alone is insufficient.

## 심화 해설

Clinical Context and Initial Assessment

This patient presents with a classic triad of a hypertensive emergency: severely elevated blood pressure (180/110 mmHg), neurological symptoms (severe headache, nausea), and cardiopulmonary symptoms (chest pain, shortness of breath). The presence of acute symptoms alongside the elevated pressure indicates acute hypertension-mediated organ damage (HMOD), which distinguishes a true emergency from hypertensive urgency. The cardiopulmonary complaints specifically raise concern for a cardiological hypertensive emergency (CHE), which encompasses life-threatening conditions such as acute coronary syndrome, acute heart failure, or acute pulmonary edema [1].

Analysis of the Correct Answer (Option 1)

Initiating continuous cardiac monitoring and preparing for antihypertensive therapy is the correct immediate priority. The rationale is twofold. First, the patient’s report of chest pain and shortness of breath strongly suggests acute cardiac HMOD. Continuous monitoring is essential to detect dynamic changes such as dysrhythmias or ST-segment shifts that would confirm a specific diagnosis like acute coronary syndrome and guide urgent treatment [1]. Second, the goal of initial management in a hypertensive emergency is not to normalize blood pressure instantly but to achieve a controlled, gradual reduction using intravenous agents to prevent hypoperfusion while halting organ damage. Preparing for this therapy is a critical nursing action that facilitates timely physician intervention. A systematic review confirms that the cornerstone of management is the prompt, controlled lowering of blood pressure with specific pharmacological agents in a monitored setting to prevent irreversible organ damage [2].

Analysis of Incorrect Answers

Option 2: Administer sublingual nitroglycerin to reduce blood pressure quickly

This is incorrect and potentially dangerous as a primary action. While sublingual nitroglycerin may be used in specific CHE scenarios like acute pulmonary edema, its rapid and unpredictable blood pressure-lowering effect can be harmful. A precipitous drop in pressure can compromise cerebral and coronary perfusion, leading to ischemic stroke or myocardial infarction. Current evidence-based guidelines emphasize controlled blood pressure reduction with titratable intravenous agents, not the rapid shifts caused by sublingual boluses [2]. The nurse must not administer this without a specific order in the context of a generalized hypertensive emergency.

Option 3: Position the patient in Trendelenburg position to improve cerebral perfusion

This action is contraindicated. The Trendelenburg position (head down) increases intracranial pressure and central venous pressure. In a patient with a severe headache and severely elevated blood pressure, this could worsen cerebral edema and increase the risk of hemorrhagic stroke. It also increases cardiac preload, which would be detrimental if the patient is developing acute heart failure, a key concern given the presenting symptoms [1]. The appropriate positioning is typically semi-Fowler’s or supine with the head elevated to reduce intracranial pressure and ease the work of breathing.

Option 4: Encourage the patient to perform deep breathing exercises to reduce anxiety

While anxiety can transiently elevate blood pressure, attributing a pressure of 180/110 mmHg with acute symptoms to anxiety is a critical error. This approach delays life-saving medical intervention. Hypertensive emergencies are driven by pathological vasoconstriction and volume overload, not by anxiety. A study on determinants of hypertensive crisis highlights that these events are associated with specific physiological and risk factors, not simply acute stress . Addressing anxiety is a secondary comfort measure that should never take precedence over hemodynamic monitoring and preparation for definitive pharmacological treatment.References (research sources)

## 임상 시나리오

Hypertensive Emergency: Immediate Nursing PrioritiesRecognizing acute HMOD and initiating controlled intervention
A blood pressure of 180/110 mmHg with acute symptoms like severe headache, chest pain, or dyspnea signals a hypertensive emergency, not just urgency. The key differentiator is the presence of acute hypertension-mediated organ damage (HMOD).

The immediate priority is to initiate continuous cardiac monitoring to detect life-threatening dysrhythmias or ischemic changes, especially with cardiopulmonary symptoms. Simultaneously, prepare for intravenous antihypertensive therapy to achieve a controlled, gradual reduction in mean arterial pressure by no more than 25% within the first hour.

CautionAvoid rapid-acting oral agents like sublingual nitroglycerin for initial BP control; they can cause unpredictable, precipitous drops leading to cerebral or myocardial hypoperfusion. The goal is to halt organ damage, not to normalize the BP reading immediately.

## 핵심 개념

- **Hypertensive Emergency** — Severe BP elevation (>180/120 mmHg) with acute, progressive target organ damage requiring immediate BP reduction (not necessarily to normal) with IV agents.
- **Acute HMOD** — Acute Hypertension-Mediated Organ Damage, affecting heart (ACS, pulmonary edema), brain (encephalopathy, stroke), kidneys, or aorta.
- **Cardiological Hypertensive Emergency** — Subset of hypertensive emergency involving acute coronary syndrome, acute heart failure, or pulmonary edema, presenting with chest pain/dyspnea.
- **Controlled BP Reduction** — Lowering MAP by no more than 25% within the first hour to prevent cerebral or coronary hypoperfusion while halting organ damage.
- **Continuous Cardiac Monitoring** — Ongoing ECG surveillance to detect dysrhythmias, ST-segment changes, or other signs of acute cardiac ischemia in a patient with suspected HMOD.
