Adrenal crisis (Addisonian crisis) is a life-threatening emergency that occurs in patients with Addison's disease when cortisol and aldosterone are severely deficient. This condition can be triggered by stress, infection, surgery, or sudden discontinuation of corticosteroid therapy. Pathophysiologically, severe depletion of glucocorticoids and mineralocorticoids leads to profound hypotension, dehydration, hyperkalemia, hyponatremia, and hypoglycemia. Without immediate intervention, cardiovascular collapse and death can occur within hours. The priority nursing intervention is to establish intravenous access and administer hydrocortisone intravenously. The reasons are: - Intravenous administration ensures rapid absorption and immediate therapeutic effect - Oral medications may not be absorbed due to vomiting or gastrointestinal dysfunction - Hydrocortisone provides both glucocorticoid and mineralocorticoid effects - Immediate corticosteroid replacement is essential to prevent cardiovascular collapse The typical emergency dose is hydrocortisone 100-300 mg intravenously, followed by continuous infusion or repeated doses every 6-8 hours. This intervention must be performed before other supportive treatments, as delay can result in irreversible shock and death. Additional supportive care includes intravenous fluid resuscitation with normal saline, electrolyte monitoring and correction, and treatment of precipitating factors, but these are secondary to immediate corticosteroid replacement. ## 심화 해설 Understanding Acute Adrenal Crisis An acute adrenal crisis, also known as an Addisonian crisis, is a life-threatening endocrine emergency. In a client with Addison's disease, the adrenal glands cannot produce sufficient glucocorticoids (primarily cortisol) and mineralocorticoids (aldosterone). When the body faces a physiological stressor—such as an infection, surgery, or, as noted in the provided case studies, a gastrointestinal illness—the demand for cortisol surges. The inability to meet this demand precipitates a crisis characterized by severe hypotension, hypovolemia, hyponatremia, and hyperkalemia, which can rapidly progress to shock and cardiovascular collapse [3,4]. Establishing Priorities: The "First" Intervention In the NCLEX-RN framework, when a client is deteriorating with signs of shock from adrenal crisis, the nurse's immediate priority is to restore circulatory volume and administer parenteral glucocorticoids without delay. The systematic review on preventing adrenal crisis highlights that despite behavioral interventions, the incidence of crisis remains high, underscoring the critical nature of prompt, protocol-driven treatment when prevention fails . The intervention that directly addresses the underlying pathophysiology and the immediate threat to life is establishing IV access and administering IV hydrocortisone. Oral medications (oral hydrocortisone) are contraindicated in an acute crisis due to hemodynamic instability and potential gastrointestinal dysfunction, which impair absorption. A patient with nausea, vomiting, and hypotension, as described in the case reports, cannot reliably absorb oral drugs [3,4]. Monitoring blood glucose is important because cortisol deficiency can lead to hypoglycemia, but it is an assessment, not a life-saving intervention to reverse shock. Encouraging oral fluid intake is inappropriate for a client who may have an altered level of consciousness or severe nausea and is in a state of vascular collapse; these clients require aggressive IV fluid resuscitation with 0.9% sodium chloride or 5% dextrose in 0.9% sodium chloride to correct volume deficit and potential hypoglycemia. Clinical Decision Support and Timely Glucocorticoid Administration The urgency of IV access and glucocorticoid administration is further validated by research on emergency department management. A study evaluating clinical decision support systems found that a primary goal in adrenal insufficiency management is minimizing the time to glucocorticoid administration, as delays are directly linked to poor outcomes . The nurse's first action—securing IV access and initiating an IV hydrocortisone bolus (typically 100 mg)—directly mirrors this evidence-based priority. This action simultaneously begins to reverse the cortisol deficiency that is driving the shock. Following the initial bolus, continuous IV infusion or frequent IV boluses are administered, along with large-volume IV fluids, to stabilize the client. The profound electrolyte disturbances, such as the hyponatremia of 106 mmol/L and hyperkalemia seen in crisis, begin to correct with fluid resuscitation and glucocorticoid replacement, which restores mineralocorticoid activity . ## 임상 시나리오 Adrenal Crisis: First ResponseImmediate Nursing Priority for Shock In a client with Addison's disease showing signs of acute adrenal crisis, the first action is to establish IV access and administer IV hydrocortisone. This directly treats the underlying cortisol deficiency causing severe hypotension and shock. Administer 100 mg of IV hydrocortisone as a bolus, followed by 200 mg over 24 hours as a continuous infusion or divided doses. Simultaneously, begin rapid IV fluid resuscitation with 0.9% normal saline or 5% dextrose in normal saline to correct hypovolemia and hyponatremia. CautionNever delay parenteral steroids for diagnostic tests. Oral medications are contraindicated due to hemodynamic instability and risk of aspiration. Monitor for hyperkalemia and hypoglycemia after initial stabilization. ## 핵심 개념 - **Adrenal Crisis** — A life-threatening emergency caused by a severe lack of cortisol, leading to shock, hyponatremia, and hyperkalemia. - **IV Hydrocortisone** — Parenteral glucocorticoid administered immediately in adrenal crisis to replace deficient cortisol and stabilize blood pressure. ## 같은 주제 문제 - [A nurse is assessing a client for suspected primary adrenal insufficiency (Addison's disea…](https://mymerci.kr/pages/nclex_q.php?qn_id=540413) - [A nurse is assessing a 58-year-old male client who presents to the emergency department wi…](https://mymerci.kr/pages/nclex_q.php?qn_id=540414) - [A nurse is assessing a 39-year-old client who presents to the emergency department with co…](https://mymerci.kr/pages/nclex_q.php?qn_id=540415) - [A nurse is assessing a patient with suspected Addison's disease.
