NBRC Practice Test 2 2026/2027 – 100+ Questions & Verified Answers | Mechanical Ventilation, Patient Assessment, Airway Care, PFT, Oxygen Therapy & Respiratory Procedures | National Board for Respiratory Care

This comprehensive NBRC Practice Test 2 2026/2027 contains 100+ respiratory care practice questions with answers across 38 pages, covering high-yield concepts in patient assessment, mechanical ventilation, airway management, oxygen therapy, pulmonary function testing, cardiopulmonary monitoring, respiratory equipment, neonatal care, and therapeutic procedures. The questions use clinical scenarios, calculations, equipment troubleshooting, and multiple-choice problems to reinforce the decision-making skills expected of respiratory therapy students and NBRC exam candidates. A major focus is mechanical ventilation and ventilator management. The material reviews pressure-cycled and volume-cycled ventilation, high-frequency jet ventilation, PEEP, inspiratory flow, I:E ratios, ventilator alarms, assisted breaths, pressure-limited ventilation, static and dynamic compliance, airway resistance, weaning parameters, respiratory muscle strength, tidal volume, and ventilator troubleshooting. Students also encounter clinical situations involving falling blood pressure and cardiac output after PEEP changes, ventilator failure to cycle, ruptured endotracheal tube cuffs, low exhaled volumes, and strategies for reducing barotrauma. The patient assessment and cardiopulmonary monitoring questions cover thoracentesis and pleural-fluid findings, congestive heart failure, pulmonary edema, pneumothorax, atelectasis, pneumonia, bronchospasm, pulmonary fibrosis, pulmonary embolism considerations, capnography, chest radiograph interpretation, arterial-line waveforms, pulmonary artery pressure, pulmonary capillary wedge pressure, CVP, systemic vascular resistance, cardiac index, hypovolemia, ECG assessment, and tissue oxygenation. Clinical findings such as butterfly-pattern infiltrates, hyperresonant percussion, bilateral wheezing, air bronchograms, and pleural-fluid characteristics are incorporated into the scenarios. The document provides substantial preparation in airway care and artificial airway management, including oropharyngeal airways, nasotracheal and endotracheal tubes, suction catheter selection, tracheostomy management, cuff pressures, cuff rupture, extubation assessment, nasal intubation equipment, secretion management, and airway complications. Questions require students to determine appropriate interventions when patients develop problems such as airway leaks, difficulty handling secretions, inadequate suctioning, or tracheostomy displacement. Students also receive practice with oxygen therapy and respiratory equipment. Topics include Venturi masks and air-entrainment devices, FiO2, air-to-oxygen ratios, oxygen concentrators, E-cylinder duration calculations, transtracheal oxygen catheters, large-volume nebulizers, ultrasonic nebulizers, humidification systems, heat-moisture exchangers, oxygen analyzers, home oxygen equipment, and oxygen delivery during transport. The guide includes calculations involving total flow, cylinder duration, and oxygen concentrations alongside equipment troubleshooting questions. The pulmonary function and diagnostic testing content includes spirometer calibration, vital capacity maneuvers, total lung capacity, helium dilution, body plethysmography, single-breath nitrogen testing, airway hyperreactivity, VD/VT ratios, pulmonary mechanics, and measurement of volume and flow. Questions also examine the use of equipment such as water-sealed spirometers, pneumotachometers, Wright respirometers, and dry-rolling spirometers. Additional clinical topics include incentive spirometry, bronchial hygiene, postural drainage, percussion, secretion mobilization, aerosol therapy, metered-dose inhalers, spacers and holding chambers, heliox therapy, obstructive sleep apnea, resuscitation equipment, infection control, and pulmonary rehabilitation-related care. The scenarios connect respiratory therapy equipment with the clinical conditions for which it may be selected or adjusted. The practice test also incorporates neonatal and pediatric respiratory care, including premature infant oxygenation, patent ductus arteriosus assessment using transcutaneous oxygen measurements, oxygen hoods, croup, pediatric extubation assessment, and high-frequency ventilation. This makes the material relevant for candidates reviewing both adult and neonatal/pediatric respiratory therapy concepts. Calculation-based material reinforces practical respiratory care skills, including static lung compliance using tidal volume divided by plateau pressure minus PEEP, oxygen-cylinder duration, air-to-oxygen ratios, total flow from air-entrainment systems, suction catheter sizing, and interpretation of ventilator measurements. The combination of calculations and bedside scenarios provides targeted practice for students preparing to apply respiratory care principles under exam conditions. Relevant Students This document is relevant for NBRC exam candidates, respiratory therapy students, respiratory care students, CRT candidates, RRT-track students, respiratory therapy graduates, cardiopulmonary science students, pulmonary function students, mechanical ventilation students, neonatal and pediatric respiratory care students, and practicing respiratory therapists reviewing examination concepts. It is particularly useful for students seeking focused practice in ventilator management, airway care, patient assessment, pulmonary diagnostics, oxygen delivery systems, cardiopulmonary monitoring, respiratory calculations, and clinical decision-making.
