A 32-year-old patient with Addison's disease is admitted to the emergency department with severe nausea, vomiting, and hypotension. The patient appears dehydrated and reports extreme fatigue. Vital signs are: BP 80/50 mmHg, HR 120 bpm, temperature 99.2°F (37.3°C). What is the nurse's priority action?

**정답: 2**

## 해설

In adrenal crisis (Addisonian crisis), immediate IV corticosteroid replacement is the priority life-saving intervention. The patient cannot absorb oral medications due to severe nausea and vomiting, and IV access is essential for rapid fluid and steroid replacement.

This question assesses the nurse's ability to recognize an adrenal crisis (Addisonian crisis) occurring in a patient with Addison's disease and determine the priority intervention. Addison's disease is a primary adrenal insufficiency in which the adrenal cortex does not produce enough cortisol and aldosterone.

In an adrenal crisis, the patient experiences severe dehydration, electrolyte imbalances, hypotension, and potential cardiovascular collapse due to cortisol and aldosterone deficiency. Pathophysiologically, cortisol deficiency leads to decreased gluconeogenesis, increased insulin sensitivity, and an inability to maintain blood pressure during stress. Aldosterone deficiency causes sodium loss, potassium retention, and decreased fluid volume.

The priority nursing action is to establish IV access for immediate corticosteroid administration. The reasons are: 1) oral medication absorption is impossible due to severe nausea and vomiting, 2) IV corticosteroids provide rapid systemic availability, 3) immediate steroid replacement is essential to prevent cardiovascular collapse, and 4) the IV line allows simultaneous fluid resuscitation with normal saline.

This is a medical emergency requiring immediate intervention. Delaying corticosteroid administration can lead to shock, coma, and death. The nurse must recognize the urgency, facilitate prompt medical intervention, and prepare for potential complications such as severe hypoglycemia and electrolyte disturbances.

Clinical Context & Pathophysiology

This patient with Addison's disease is presenting with the classic triad of an adrenal crisis (AC): severe nausea and vomiting, profound hypotension (BP 80/50 mmHg), and extreme fatigue. Addison's disease is a form of primary adrenal insufficiency (AI) where the adrenal cortex fails to produce sufficient glucocorticoids (cortisol) and mineralocorticoids (aldosterone). During a physiological stressor like vomiting and dehydration, the body cannot mount the necessary cortisol response, leading to distributive shock, vascular collapse, and potential death if untreated. The tachycardia (HR 120 bpm) is a compensatory mechanism for the low blood pressure and hypovolemia. An adrenal crisis is a life-threatening emergency requiring rapid recognition and immediate administration of stress-dose glucocorticoids, as delays in treatment can be fatal [1].

Priority Action Analysis

The nurse's priority action is to establish IV access and prepare for immediate IV corticosteroid administration. In an acute adrenal crisis, the cornerstone of management is the rapid restoration of glucocorticoid levels with parenteral stress-dose steroids. Because the patient is vomiting and hemodynamically unstable, the oral route is unreliable and contraindicated. The immediate goal is to reverse the shock state and prevent cardiovascular collapse. Simulation-based education studies highlight that a critical gap in resident knowledge is the failure to immediately administer stress-dose glucocorticoids, underscoring the urgency of this intervention [1]. The patient's presentation of hypotension and vomiting makes IV administration the only safe and effective route for rapid drug delivery.

Why the Other Options Are Incorrect

Option 1 (Administer oral hydrocortisone 20 mg immediately): This is incorrect and dangerous. The patient has severe nausea and vomiting, making oral intake unreliable due to the risk of aspiration and poor absorption. More critically, oral hydrocortisone is part of a "sick-day" management plan for preventing a crisis, not for treating an established, life-threatening adrenal crisis with shock. An acute crisis demands immediate, high-dose parenteral glucocorticoids .

Option 3 (Obtain blood samples for cortisol levels before any treatment): This is a critical error in prioritization. While a random cortisol level can be a helpful diagnostic clue, treatment must never be delayed to perform diagnostic tests. In a known Addison's disease patient with clear signs of shock, waiting for a blood draw would dangerously postpone life-saving intervention. The clinical diagnosis of adrenal crisis is sufficient to warrant immediate treatment [1].

Option 4 (Position the patient in Trendelenburg position and monitor vital signs): This is a supportive, not a definitive, intervention. While monitoring and positioning are nursing responsibilities, they do not address the underlying cause of the shock, which is a critical lack of cortisol. The priority is to administer the medication that will correct the pathophysiology. Positioning is a secondary action that can be performed concurrently after the IV line is established and the corticosteroid infusion is prepared. Effective self-management and education for AI patients focus on the primacy of parenteral glucocorticoid administration during an emergency, not just supportive care .References (research sources)

## 임상 시나리오

Adrenal Crisis: Priority Nursing ActionImmediate IV Glucocorticoid Administration
In a patient with Addison's disease presenting with hypotension, vomiting, and fatigue, suspect an adrenal crisis. This is a life-threatening emergency where the body cannot mount a stress response due to a lack of cortisol, leading to distributive shock.

The immediate priority is to establish IV access and administer stress-dose IV corticosteroids (e.g., hydrocortisone 100 mg IV bolus). Do not delay treatment to obtain blood samples; a cortisol level can be drawn during line insertion but must not postpone the life-saving bolus.

CautionThe oral route is absolutely contraindicated in an acute crisis due to vomiting and hemodynamic instability. Delaying parenteral steroids to attempt oral intake or wait for lab results can lead to cardiovascular collapse and death.

## 핵심 개념

- **Adrenal Crisis** — A life-threatening emergency in adrenal insufficiency characterized by severe hypotension, vomiting, and vascular collapse due to a lack of cortisol.
- **Addison's Disease** — Primary adrenal insufficiency where the adrenal cortex fails to produce sufficient glucocorticoids and mineralocorticoids.
- **Stress-Dose Steroids** — High doses of parenteral glucocorticoids administered to mimic the body's natural stress response during critical illness or crisis.
- **Distributive Shock** — A type of shock resulting from severe vasodilation and vascular leakage, leading to poor tissue perfusion, as seen in adrenal crisis.
