TMC Practice Exam 2026/2027 – 100+ Questions & Answers | Mechanical Ventilation, ABGs, Airway Management, Oxygen Therapy, PFTs & Respiratory Care

This comprehensive TMC Practice Exam 2026/2027 provides 100+ respiratory therapy exam questions with answers across 78 pages, covering mechanical ventilation, airway management, arterial blood gases, oxygen therapy, pulmonary function testing, cardiopulmonary assessment, respiratory pharmacology, bronchial hygiene, emergency respiratory care, neonatal and pediatric respiratory care, and clinical decision-making. The questions are presented primarily as patient-based scenarios requiring the learner to interpret clinical findings, select appropriate respiratory interventions, troubleshoot equipment, perform calculations, and determine treatment priorities. A major portion of the material focuses on mechanical ventilation and ventilator management. Students encounter volume-controlled and pressure-controlled ventilation, SIMV, assist/control ventilation, pressure support, CPAP, NPPV, PEEP, auto-PEEP, APRV, HFOV, inspiratory flow patterns, tidal volume, respiratory rate, inspiratory time, pressure limits, ventilator alarms, patient-ventilator interaction, dynamic hyperinflation, lung compliance, spontaneous breathing trials, and extubation decisions. The scenarios require interpretation of ventilator settings alongside ABGs, SpO2, ETCO2, airway pressures, clinical presentation, and chest radiographs. Airway management and artificial airways are extensively represented. Questions address endotracheal tube sizing and positioning, tracheostomy tubes, cuff pressure and inflation techniques, suction catheter selection, airway suctioning, post-extubation stridor, endobronchial intubation, airway obstruction, emergency reintubation, bronchoscopy, tracheostomy complications, and maintenance of airway patency. Students also practice recognizing findings such as unilateral breath sounds, tracheal deviation, high ventilator pressures, reduced tidal volumes, and sudden capnographic changes. The exam provides substantial practice with arterial blood gases and cardiopulmonary calculations. Clinical cases require interpretation of pH, PaCO2, PaO2, HCO3, SaO2, PvO2, SvO2 and base excess, together with calculations or interpretation involving C(a-v)O2, static lung compliance, oxygen delivery, dead-space measurements and other respiratory parameters. Proper ABG collection and handling, complications following arterial puncture, and clinical interpretation of abnormal gas values are also tested. Oxygen therapy and oxygenation monitoring form another important section. Questions cover nasal cannulas, air-entrainment masks, nonrebreathing masks, transtracheal oxygen, oxygen flow calculations, helium-oxygen mixtures, pulse oximetry, hemoximetry, oxygen toxicity considerations, hyperbaric oxygen therapy, and oxygen management in patients with COPD or emphysema. The material also asks students to distinguish hypoxemia caused by ventilation/perfusion mismatch and other physiological abnormalities. The practice material covers pulmonary function testing and respiratory diagnostics, including FVC, FEV1, FEV1/FVC, PEFR, slow vital capacity, flow-volume loops, bedside spirometry, spirometer calibration, bronchodilator reversibility testing, bronchial provocation, peak-flow monitoring, sleep studies, apnea-hypopnea index, capnography, transcutaneous monitoring and chest radiograph interpretation. Learners must differentiate normal pulmonary function from obstructive or restrictive findings and recognize patterns associated with large-airway obstruction. Students also receive extensive practice with bronchial hygiene and lung-expansion therapy. The document addresses incentive spirometry, IPPB, PEP therapy, oscillatory PEP, intrapulmonary percussive ventilation, postural drainage and percussion, coughing and deep breathing, secretion mobilization, humidification and airway clearance for conditions such as cystic fibrosis, pneumonia, atelectasis, chronic bronchitis and postoperative pulmonary complications. The cardiopulmonary assessment questions integrate heart failure, pulmonary edema, pulmonary embolism, cardiac tamponade, hemodynamic monitoring, pulmonary artery pressure, pulmonary capillary wedge pressure, central venous pressure, cardiac output and mixed venous oxygen measurements. The document uses clinical findings such as jugular venous distension, edema, chest radiographs, BNP results and invasive hemodynamic values to test recognition of cardiovascular conditions relevant to respiratory care. Respiratory disease management includes asthma, COPD, emphysema, chronic bronchitis, pneumonia, cystic fibrosis, pleural effusion, pneumothorax, atelectasis, pulmonary edema, acute lung injury and respiratory distress syndromes. Emergency scenarios test recognition and management of tension pneumothorax, severe asthma, hypoventilation, airway compromise, pleural fluid accumulation and other acute respiratory problems. The pharmacology component incorporates albuterol, levalbuterol, racemic epinephrine, dornase alfa, inhaled nitric oxide, neuromuscular blockers and other respiratory medications. Questions require students to select appropriate aerosol medications, calculate medication volumes, monitor treatment effectiveness and adverse responses, and modify therapy based on clinical findings. The document additionally includes neonatal and pediatric respiratory care, with questions involving APGAR scoring, Silverman scoring, neonatal respiratory distress, inhaled nitric oxide, transcutaneous monitoring, home apnea monitoring, pediatric oxygen monitoring and respiratory assessment. This expands the practice beyond adult respiratory care and prepares students to apply respiratory principles across different age groups. Clinical safety and professional practice are reinforced through questions on infection prevention, equipment cleaning and disinfection, respiratory care protocols, home oxygen safety, medical record orders, patient education, transport considerations and respiratory equipment troubleshooting. Overall, the document is structured around applied clinical decision-making rather than simple factual recall, making it useful for practicing the assessment, analysis and intervention skills tested in respiratory therapy examinations. Relevant Students This document is relevant for TMC exam candidates, respiratory therapy students, respiratory care students, respiratory therapist certification candidates, CRT candidates, RRT-track students, associate and bachelor-level respiratory care students, clinical respiratory therapy students, cardiopulmonary care students, and graduates preparing for respiratory therapy board-style examinations. It is especially useful for learners reviewing mechanical ventilation, ABG interpretation, airway management, oxygen delivery, pulmonary diagnostics, respiratory pharmacology, bronchial hygiene, emergency care, neonatal respiratory care and cardiopulmonary monitoring.
