BSN 445 Week 6 Sherpath 2026/2027 – 35+ Questions & Answers | Shock, Sepsis, ARDS, MODS & Critical Care

This BSN 445 Week 6 Sherpath 2026/2027 exam preparation resource contains 35+ questions with correct answers across 26 pages, providing an in-depth review of shock, tissue perfusion, hypovolemic shock, anaphylactic shock, cardiogenic shock, neurogenic shock, septic shock, acute respiratory distress syndrome (ARDS), and multiple organ dysfunction syndrome (MODS). The document emphasizes recognition of early clinical deterioration, interpretation of hemodynamic and laboratory findings, prioritization of emergency interventions, and prevention of complications in critically ill patients. Early questions address subtle manifestations of shock such as restlessness and reduced mean arterial pressure, airway and oxygenation assessment, serum lactate as an indicator of impaired tissue perfusion, fluid resuscitation, and passive leg raising as a method of assessing fluid responsiveness. The hypovolemic shock section examines classification and recognition of progressive circulatory compromise through heart rate, respiratory rate, blood pressure, pulse pressure, temperature, and clinical manifestations. Students review intravenous crystalloid therapy, fluid-volume management, nutritional risks, urine-output monitoring, oxygen administration, and emergency assessment following significant blood loss. The resource also connects progressive shock with hematologic complications such as thrombocytopenia and disseminated intravascular coagulation (DIC), including bleeding from venipuncture sites, hypotension, dyspnea, and other signs of systemic deterioration. A substantial portion covers anaphylaxis and anaphylactic shock. Questions address potential latex exposure from hospital products, transfusion-related allergic reactions, pruritus and systemic manifestations of anaphylaxis, obtaining a comprehensive allergy history before contrast-enhanced imaging, and recurrent or biphasic anaphylactic reactions. Pharmacologic management includes epinephrine-related concepts, antihistamine therapy, crystalloid resuscitation, and the use of intravenous glucagon when beta-blocker therapy reduces responsiveness to epinephrine. These scenarios emphasize rapid recognition of airway, breathing, and circulatory compromise following severe hypersensitivity reactions. The cardiogenic shock material connects impaired myocardial contractility with reduced tissue perfusion and altered hemodynamics. Students review myocardial infarction, heart failure, ventricular pump failure, ejection fraction, cardiac index, pulmonary artery occlusion pressure, right atrial pressure, increasing oxygen requirements, pulmonary assessment, intake and output, and dysrhythmias such as atrial fibrillation. The questions require learners to interpret both bedside assessment findings and invasive hemodynamic values when determining whether cardiovascular dysfunction is producing inadequate systemic perfusion. Another major section differentiates neurogenic and septic forms of distributive shock. Neurogenic shock questions highlight characteristic hypotension, bradycardia, temperature dysregulation, spinal cord injury, mean arterial pressure assessment, venous thromboembolism prevention, sequential compression devices, anticoagulant prophylaxis, and passive range-of-motion exercises. Sepsis questions address major risk factors such as immunosuppression and central venous access, altered mental status, respiratory rate, quick SOFA concepts, procalcitonin, hyperglycemia, elevated lactate, blood cultures, antibiotics, crystalloid resuscitation, and glucose management. The document then connects septic shock with ARDS and progressive organ dysfunction. Students review the PaO2/FiO2 ratio, noncardiogenic pulmonary edema, persistent hypoxemia, increasing oxygen requirements, tachypnea, and indications for mechanical ventilation. ARDS management concepts include positive end-expiratory pressure (PEEP), prone positioning, oxygen-delivery optimization, sedation, and supportive critical-care interventions. Renal impairment is addressed through oliguria, serum creatinine, creatinine clearance, glomerular filtration, and medication-dose adjustment in critically ill patients. The final portion focuses extensively on multiple organ dysfunction syndrome (MODS) and reperfusion injury. Questions integrate respiratory failure, acute kidney injury, gastrointestinal dysfunction, acalculous cholecystitis, hyperglycemia, hypotension, coagulation abnormalities, nutritional support, mechanical ventilation, and hyperdynamic cardiovascular function. Students review why the kidneys require close monitoring following reperfusion injury and how widespread infection and systemic inflammation can progress from sepsis and shock to simultaneous dysfunction of several organ systems. Enteral nutrition, including post-pyloric feeding, is also examined as part of supportive management for critically ill ventilated patients. For authoritative academic reinforcement, the shock and critical-care concepts correspond broadly with AACN Essentials of Critical Care Nursing and Lewis’s Medical-Surgical Nursing: Assessment and Management of Clinical Problems. Sepsis and septic-shock management should be compared with the current Surviving Sepsis Campaign international guidelines, while anaphylaxis management can be cross-referenced with contemporary guidance from organizations such as the World Allergy Organization. ARDS assessment and ventilatory management should similarly be verified against current critical-care and pulmonary literature. These sources are especially important because recommendations involving sepsis bundles, fluid administration, vasopressors, glucose targets, mechanical ventilation, and anaphylaxis treatment can evolve, and current evidence-based guidance should take precedence over older practice-question answers. Relevant Students: This document is particularly relevant for BSN 445 students, Sherpath nursing students, BSN and RN students, critical care nursing students, ICU nursing students, adult health and medical-surgical nursing students, and learners preparing for examinations involving shock and multiple-organ failure. It is also useful for students reviewing hypovolemic, cardiogenic, anaphylactic, neurogenic and septic shock, hemodynamics, tissue perfusion, DIC, sepsis, ARDS, MODS, mechanical ventilation, fluid resuscitation, critical-care pharmacology, and nursing prioritization.
