It is characterized by insufficient tissue perfusion despite normal or increased cardiac output. Key signs include hypotension, tachycardia, and warm, flushed skin due to peripheral vasodilation. Pathophysiologically, widespread vasodilation occurs due to the release of inflammatory mediators or loss of sympathetic nervous system regulation. Blood pools in peripheral vessels, reducing venous return and effective circulating blood volume. Although intravascular volume is adequate, the expanded vascular space causes relative hypovolemia. The priority nursing intervention is administration of prescribed vasopressors. Medications like norepinephrine or dopamine cause vasoconstriction, increasing systemic vascular resistance and restoring adequate blood pressure for organ perfusion. Without prompt vasopressor therapy, the patient can rapidly progress to irreversible shock and multiple organ failure. Fluid resuscitation is also important but may not be sufficient alone in distributive shock since vasodilation, not absolute volume loss, is the main problem. The warm, flushed appearance indicates adequate perfusion to the skin but inadequate perfusion to vital organs due to blood flow redistribution. ## 심화 해설 Understanding Distributive Shock and the Clinical Presentation The patient's presentation—hypotension with a blood pressure of 75/50 mmHg, tachycardia at 130 bpm, and warm, flushed skin—is a classic hemodynamic profile for distributive shock, most commonly seen in early sepsis. In distributive shock, massive vasodilation leads to a profound decrease in systemic vascular resistance. The "warm and flushed" appearance is a key differentiator from other shock states like cardiogenic or hypovolemic shock, where peripheral vasoconstriction causes cool, clammy skin. This vasodilation causes blood to pool in the periphery, resulting in relative hypovolemia and inadequate tissue perfusion despite a potentially normal or even increased cardiac output. Prioritizing the Nursing Action The highest priority nursing action is to administer prescribed vasopressor medications. The underlying pathophysiological problem is a loss of vascular tone, not a primary loss of fluid volume. While fluid resuscitation is a component of initial sepsis management, the provided rationale material highlights that cardiovascular dysfunction in sepsis "frequently manifest[s] as hypotension that persists despite fluid resuscitation" [1]. This indicates that vasodilation is the dominant mechanism requiring direct pharmacological correction. Vasopressors, such as intravenous alpha-1 agonists, work by causing arterial and venous constriction, directly counteracting the pathological vasodilation to increase systemic vascular resistance and raise blood pressure to a level sufficient for organ perfusion. Analysis of Other Options - Option 2 (Increase fluid intake): Encouraging oral hydration is contraindicated in an unstable patient with distributive shock. The patient's condition impairs perfusion to the gastrointestinal tract, and altered mental status or severe illness makes oral intake unsafe due to the high risk of aspiration. Furthermore, the priority is to restore vascular tone and intravascular volume rapidly with intravenous fluids and vasoactive agents, as oral intake would be too slow and unreliable. - Option 3 (Apply cooling measures): The patient's flushed, warm skin is due to peripheral vasodilation, not a primary fever. Applying external cooling would cause peripheral vasoconstriction, which might transiently raise blood pressure but would do so by shunting blood away from the skin, masking the underlying problem and potentially worsening tissue acidosis. It does not address the core issue of systemic vasodilation. - Option 4 (High Fowler's position): Positioning the patient in high Fowler's position would exacerbate hypotension by promoting venous pooling in the lower extremities due to gravity. This reduces venous return to the heart (preload), which would further drop cardiac output and blood pressure. The correct positioning for a patient in shock is supine with legs elevated (modified Trendelenburg) to promote venous return, unless contraindicated. Clinical Application and Pharmacological Link The rationale for prioritizing vasopressor administration is directly supported by the clinical context of vasopressor dependence in sepsis. The research protocol notes that most patients with persistent hypotension "require the use of intravenous vasoactive agents" and that these agents are central to management, often necessitating ICU-level monitoring [1]. The study further investigates midodrine, an oral alpha-1 agonist, as a strategy for "vasopressor-sparing," which underscores the critical role of vasopressors in the acute phase. For the NCLEX-RN, recognizing that distributive shock is fundamentally a problem of decreased vascular tone guides the nurse to anticipate and prioritize the administration of vasopressor medications like norepinephrine as the immediate, life-saving intervention to restore perfusion pressure.References (research sources) - [1]Midodrine for Sepsis Treatment and Early Vasopressor Weaning (MID-STEP): protocol for a pragmatic randomised clinical trial.RCT/clinical trialTekin A, Halpern G, Gowda D, Bansal V, Schuchard A, Joguncic A, Schulte P, Odeyemi YE, Ahmad S, Madsen B, Rizwan Z, Barreto EF, Reddy S, Bhavsar V, Sanghavi D, Domecq Garces JP, Khan SA, Shiari A, Cartin-Ceba R, Gajic O, Lal A. (2026) · DOI: 10.1136/bmjopen-2026-117846 ## 임상 시나리오 Clinical Management of Distributive Shock Rapid Identification - Recognize the classic triad: hypotension (e.g., MAP < 65 mmHg), tachycardia, and warm, flushed skin. This differentiates distributive shock from cardiogenic or hypovolemic shock, which present with cool, clammy skin. - Assess for a suspected source of infection immediately, as sepsis is the most common cause. Obtain blood cultures and a serum lactate level without delaying treatment. Immediate Priority Interventions - **Administer Vasopressors:** The highest priority is to correct the pathological vasodilation. Initiate a prescribed intravenous vasopressor, such as norepinephrine, through a central line to increase systemic vascular resistance and achieve a target MAP of 65 mmHg or greater. - **Initiate IV Fluid Resuscitation:** Concurrently, begin rapid infusion of 30 mL/kg of an isotonic crystalloid solution (e.g., Lactated Ringer's or 0.9% sodium chloride) as part of the initial sepsis bundle, unless contraindicated. This addresses relative hypovolemia. - **Positioning:** Keep the patient supine or in a modified Trendelenburg position to promote venous return. Avoid high Fowler's position, which can worsen hypotension. Ongoing Monitoring and Reassessment - Continuously monitor blood pressure, heart rate, and oxygen saturation. Titrate vasopressor therapy to maintain the prescribed MAP goal. - Assess for signs of fluid overload, such as crackles on lung auscultation, especially once vasopressors are initiated and vascular tone returns. - Monitor urine output as an indicator of renal perfusion and end-organ function. A target of >0.5 mL/kg/hr is desired. ## 핵심 개념 - **Distributive Shock** — Shock caused by blood vessel dilation leading to insufficient effective circulating blood volume. The intravascular volume is normal, but the expanded vascular space results in relative hypovolemia. This includes septic, neurogenic, and anaphylactic shock. - **Vasopressor** — Drugs that constrict blood vessels to raise blood pressure (e.g., norepinephrine, dopamine). They are essential for restoring vascular tone in distributive shock. - **Warm Shock** — A clinical manifestation of distributive shock. Due to peripheral vasodilation, the skin is warm and flushed, but it is actually accompanied by inadequate perfusion of vital organs and hypotension. - **Relative Hypovolemia** — A state where blood volume becomes relatively insufficient due to expansion of the vascular space, rather than an absolute decrease in blood volume. This is the main pathophysiology of distributive shock. - **Systemic Vascular Resistance** — Systemic vascular resistance. It is the resistance that blood vessels provide against blood flow. In distributive shock, SVR is markedly reduced, and vasoconstrictors aim to increase it. ## 같은 주제 문제 - [A nurse is caring for a patient in the emergency department who presents with signs of dis…](https://mymerci.kr/pages/nclex_q.php?qn_id=177119) - [A nurse is caring for a patient in the emergency department who presents with signs of dis…](https://mymerci.kr/pages/nclex_q.php?qn_id=177120) - [A nurse is caring for a patient in the emergency department who presents with signs of dis…](https://mymerci.kr/pages/nclex_q.php?qn_id=177121) - [A 45-year-old patient is admitted to the emergency department following a motor vehicle ac…](https://mymerci.kr/pages/nclex_q.php?qn_id=177122) - [A 45-year-old patient is admitted to the emergency department with signs of distributive s…](https://mymerci.kr/pages/nclex_q.php?qn_id=177123) - [A 35-year-old patient is brought to the emergency department following a motor vehicle acc…](https://mymerci.kr/pages/nclex_q.php?qn_id=177124) - [A 68-year-old patient with a history of coronary artery disease presents with cardiogenic …](https://mymerci.kr/pages/nclex_q.php?qn_id=177125) - [A patient in cardiogenic shock is receiving dopamine at 10 mcg/kg/min and has a central ve…](https://mymerci.kr/pages/nclex_q.php?qn_id=177126) --- More free questions: [기출문제](https://mymerci.kr/) _학습 참고용입니다. 실제 임상은 최신 지침과 소속 기관 프로토콜을 따르세요._
