BSN 445 Week 7 Sherpath 2026/2027 – 40+ Questions & Answers | Mechanical Ventilation, ARDS, Oxygen Therapy, Airways & Thoracic Surgery

This BSN 445 Week 7 Sherpath 2026/2027 exam preparation resource contains 40+ questions with correct answers across 16 pages, providing focused review of oxygen-delivery systems, artificial airways, mechanical ventilation, ARDS, ventilator-associated complications, ventilator weaning, noninvasive ventilation, positioning therapy, and postoperative thoracic surgery care. The opening section examines oxygen devices including nasal catheters, high-flow nasal cannulas, nonrebreathing masks, and air-entrainment masks, alongside assessment of oxygenation and respiratory distress. Airway-management questions cover nasopharyngeal airways, orotracheal and endotracheal tubes, tracheostomies, humidification, cuff-related care, subcutaneous emphysema, airway obstruction, accidental extubation, bag-valve-mask ventilation, and positioning of intubated patients. A major portion of the resource concentrates on mechanical ventilation and acute respiratory distress syndrome (ARDS). Students review pressure-controlled continuous mandatory ventilation, CPAP, pressure-support ventilation, tidal volume, respiratory rate, inspiratory flow, FiO2, and positive end-expiratory pressure (PEEP). Clinical scenarios require learners to recognize complications associated with positive-pressure ventilation, including decreased preload, reduced urine output, and increased intracranial pressure, while also determining appropriate interventions for patient-ventilator dyssynchrony, anxiety, and hypoxemia. The document provides detailed coverage of ventilator-associated pneumonia (VAP) prevention and mechanical-ventilation weaning. Questions address oral care, early mobilization, risk factors for VAP, negative inspiratory force, respiratory rate, rapid shallow breathing index, minute ventilation, vital capacity, and criteria for spontaneous breathing trials. Students also identify clinical findings that require termination of an SBT, including severe tachypnea, oxygen desaturation, agitation, dyspnea, and evidence of respiratory intolerance. Synchronized intermittent mandatory ventilation is additionally reviewed in the context of ventilator weaning. Critical-care nursing responsibilities extend beyond ventilator settings to sleep promotion and safe intrahospital transport of mechanically ventilated patients. The questions emphasize coordinating nursing activities with other disciplines to reduce sleep disruption and ensuring appropriate respiratory and cardiovascular monitoring during transport. Equipment considerations include a transport ventilator, blood-pressure monitoring, cardiac monitoring, and defibrillation capability. These scenarios reinforce the continuous assessment and emergency preparedness required when caring for critically ill ventilated patients. Another important section covers noninvasive ventilation (NIV), BiPAP, prone positioning, and kinetic therapy. Students review indications for discontinuing NIV, head-of-bed elevation during BiPAP, and complications such as nasal-bridge skin injury, abdominal distention, and anxiety. Prone-positioning questions assess effectiveness through improvements in arterial oxygenation and identify situations in which positioning therapy may be inappropriate, including significant cervical spinal injury. Kinetic therapy is discussed as a strategy that can reduce atelectasis and pneumonia risk in selected critically ill patients. The final section addresses lobectomy, pneumonectomy, thoracic surgery, and respiratory pharmacology. Postoperative questions cover splinting during coughing, chest-tube assessment, recognition of abnormal sputum or drainage, pain management, early ventilator weaning and extubation, central venous pressure monitoring, and prevention of complications following lung resection. Pharmacology content includes bronchodilator and airway-management agents such as theophylline and albuterol, inhaled flunisolide, acetylcysteine, epinephrine, and neuromuscular blocking agents including vecuronium, atracurium, and cisatracurium. The resource also highlights safety considerations when neuromuscular blockade is used to manage ventilator dyssynchrony. For evidence-based academic reinforcement, these subjects correspond closely with respiratory and critical-care concepts covered in AACN Essentials of Critical Care Nursing and Lewis’s Medical-Surgical Nursing: Assessment and Management of Clinical Problems. ARDS and mechanical-ventilation concepts can additionally be compared with current American Thoracic Society (ATS) clinical practice guidance and contemporary lung-protective ventilation literature. VAP prevention, artificial-airway care, ventilator liberation, prone positioning, and neuromuscular blockade should be verified against current critical-care guidelines and institutional protocols because recommended practices can change as new evidence becomes available. Relevant Students: This document is particularly relevant for BSN 445 students, Sherpath nursing students, BSN and RN students studying critical care, ICU nursing students, respiratory and pulmonary nursing students, adult health and medical-surgical nursing students, and learners preparing for examinations involving mechanical ventilation and advanced airway management. It can also support HESI, ATI Adult Medical-Surgical, NCLEX-RN, and critical-care examination preparation involving oxygen therapy, artificial airways, ARDS, ventilator settings, VAP prevention, ventilator weaning, BiPAP, prone positioning, thoracic surgery, and respiratory pharmacology.
