A nurse is caring for a client with suspected adrenal crisis (Addisonian crisis). Which nursing action should be the highest priority?

The client presents with severe hypotension, dehydration, and altered mental status following discontinuation of corticosteroid therapy.

1. Obtain blood samples for electrolyte levels and cortisol measurement
2. Administer oral hydrocortisone as prescribed
3. Monitor vital signs every 15 minutes
4. Establish IV access and prepare for immediate fluid resuscitation **✔ 정답**

**정답: 4**

## 해설

In adrenal crisis, the highest priority is establishing IV access for immediate fluid resuscitation and IV corticosteroid administration to prevent cardiovascular collapse and death.

Adrenal crisis (Addisonian crisis) is a life-threatening emergency caused by severe adrenal insufficiency. It can be triggered by stress, infection, or sudden discontinuation of corticosteroid therapy. Pathophysiologically, severe deficiency of cortisol and aldosterone leads to profound hypotension, dehydration, hyperkalemia, hyponatremia, and potential cardiovascular collapse.

The highest priority nursing action is to establish intravenous access and prepare for immediate fluid resuscitation. This is because the patient is experiencing severe hypotension and dehydration, which can rapidly progress to shock and death. Intravenous access is essential for fluid replacement and intravenous corticosteroid (hydrocortisone) administration, which are the cornerstones of adrenal crisis treatment.

Severe hypotension, dehydration, and altered mental status following corticosteroid discontinuation are classic symptoms of adrenal crisis. Without immediate intervention, the patient can develop irreversible shock. Intravenous fluid resuscitation with normal saline helps restore intravascular volume and blood pressure, while intravenous corticosteroids replace the deficient hormones.

This situation requires immediate action to prevent death, so establishing IV access and fluid resuscitation takes absolute priority over other important but less urgent interventions such as laboratory tests or vital sign measurement.

Clinical Context & Priority Setting

In a suspected Addisonian crisis, the body is experiencing a life-threatening deficiency of glucocorticoids and mineralocorticoids. This leads to a distributive shock state driven by profound hypovolemia and loss of vascular tone. The case presentations in the provided literature consistently describe initial presentations of hypotension and shock, with management centered on aggressive fluid resuscitation [2, 3]. The client’s severe hypotension and altered mental status indicate that cerebral and vital organ perfusion is critically compromised. In the NCLEX-RN prioritization framework, physiological needs that pose an immediate threat to circulation and airway take precedence. Restoring circulating volume directly addresses the pathophysiology of vascular collapse and is the most time-sensitive intervention.

Analysis of the Correct Answer (Option 3)

Establishing intravenous access and preparing for immediate fluid resuscitation is the highest priority because it directly intervenes on the mechanism causing shock. In adrenal crisis, the lack of aldosterone leads to massive sodium and water loss, causing severe hypovolemia, while cortisol deficiency contributes to poor vascular tone [1]. A case of Addisonian crisis triggered by medication non-adherence describes a presentation of hypotension that requires immediate volume replacement as a cornerstone of emergency management [1]. Similarly, a crisis precipitated by abrupt corticosteroid withdrawal resulted in hypotensive septic shock, where management explicitly included “aggressive intravenous fluids” alongside vasopressor support [2]. Without immediate IV access and fluid resuscitation, the client will not survive long enough for diagnostic tests or other monitoring to be meaningful. This action treats the "ABCs" (specifically Circulation) of emergency nursing.

Analysis of Incorrect Answers

- Option 1: Obtaining blood samples for electrolyte and cortisol levels is a critical diagnostic step to confirm the crisis and guide ongoing therapy. However, it is a secondary priority. The literature confirms that a short Synacthen test or basal cortisol measurement is used to verify adrenal insufficiency, but this occurs after or concurrently with initial stabilization, not before it [2, 3]. In an unstable patient with shock, delaying fluid resuscitation to draw labs violates the principle of managing immediate threats to life first.

- Option 2: Preparing the client for a computed tomography (CT) scan is not a priority in the acute management of a known or highly suspected Addisonian crisis. The trigger is clearly identified as corticosteroid withdrawal, and the immediate threat is hemodynamic instability. A CT scan might be considered later to investigate an underlying infectious process if one is suspected, but moving an unstable patient to the radiology department before resuscitation would be dangerous [1].

- Option 4: Monitoring vital signs and neurological status every 15 minutes is an essential ongoing nursing action for a client in shock. However, it is an assessment, not an intervention. While you will perform this monitoring, it does not actively reverse the life-threatening hypovolemia. The initial priority is to implement the intervention—fluid resuscitation—that will improve the parameters you are monitoring. Assessment is crucial, but in a crisis, action to stabilize the patient takes precedence.

Pathophysiology & Clinical Application

The abrupt discontinuation of corticosteroid therapy causes a sudden, unopposed deficit of cortisol and aldosterone in a patient with chronic adrenal suppression [2]. This triggers a cascade: the loss of aldosterone’s sodium-retaining effect leads to profound volume depletion, hyponatremia, and hyperkalemia, while the loss of cortisol’s permissive effect on vascular tone results in vasodilation and poor cardiac output. The combined effect is a rapid progression to shock. The cases from the provided evidence reinforce this, showing that triggers like medication withdrawal or physiological stress lead to a hypotensive crisis that demands immediate volume expansion with isotonic fluids as the first-line nursing action [1, 2, 4].References (research sources)

Clinical Practice Guide
This is a practice guide for when you encounter a patient with suspected adrenal crisis:
1. Immediate action: Secure intravenous access (usually a large-bore catheter) and prepare Normal Saline without waiting for a doctor's order. This is most effective for rapidly restoring intravascular volume.
2. Concurrent intervention: While securing IV access, monitor vital signs and immediately report to the physician to obtain an order for intravenous Hydrocortisone administration.
3. Caution: Oral hydrocortisone (option 2) is absolutely contraindicated in this situation. The patient is in shock, making intestinal absorption unreliable, and its effect is much slower than intravenous administration. The clue "occurred after steroid discontinuation" strongly suggests adrenal crisis, but treatment must be initiated via the intravenous route.

## 핵심 개념

- **Adrenal Crisis (Addisonian Crisis)** — A critical deficiency of cortisol and aldosterone due to sudden adrenal insufficiency. This is a life-threatening emergency that causes hypotension, shock, and electrolyte imbalances.
- **Hypovolemic Shock** — A condition where tissues cannot receive sufficient oxygen due to a rapid decrease in circulating blood volume. In adrenal crisis, dehydration and sodium loss caused by hormone deficiency are the causes.
- **Hydrocortisone** — A synthetic form of cortisol, it is the first-line treatment administered intravenously during an adrenal crisis. In addition to its anti-inflammatory and immunosuppressive effects, it is essential for maintaining blood pressure and glucose metabolism.
- **Fluid Resuscitation** — Emergency treatment that rapidly administers fluids through a vein to restore intravascular volume and tissue perfusion in cases of shock or severe dehydration.
- **Hypotension** — Lower than normal blood pressure. In an adrenal crisis, it occurs due to a combination of sodium and water loss from aldosterone deficiency, along with reduced vascular constriction from cortisol deficiency.
