NBRC TMC Exam 2026/2027 | 100+ Questions & Answers | Mechanical Ventilation, ABGs, Pulmonary Function, Airway Care & Neonatal Respiratory Therapy

This NBRC TMC Exam 2026/2027 preparation resource contains 100+ multiple-choice questions with answers across 68 pages, designed around clinical decision-making in respiratory therapy. The document combines two labeled sets, NBRC TMC Exam-Z and NBRC TMC Exam-S, and presents patient scenarios requiring selection of the most appropriate respiratory assessment, treatment, monitoring method or equipment intervention. Major areas include mechanical ventilation, oxygenation and ventilation assessment, airway management, pulmonary diagnostics, pharmacology, cardiopulmonary monitoring, pulmonary rehabilitation, neonatal care and emergency respiratory therapy. A substantial portion focuses on mechanical ventilation and ventilator management. Questions cover assist/control and SIMV ventilation, tidal volume and respiratory-rate adjustments, PEEP, FiO2, peak and plateau airway pressures, pressure-volume loops, auto-PEEP, inspiratory flow, I:E relationships, low-volume alarms, ventilator-associated pneumonia prevention and weaning. Clinical scenarios involve ARDS, COPD, status asthmaticus, pulmonary infections and postoperative respiratory failure, requiring students to interpret ventilator settings alongside ABGs, oxygenation status and respiratory mechanics. The resource provides extensive practice with arterial blood gases and cardiopulmonary monitoring. Students encounter pH, PaCO2, PaO2, HCO3-, base excess, A-aDO2, arterial versus venous samples, temperature-related blood-gas considerations and oxygen-content calculations. Other questions address capnography and PetCO2, transcutaneous oxygen monitoring, pulse oximetry, COHb, pulmonary artery catheters, pulmonary artery pressure, PCWP, cardiac output and arterial-line measurements. These scenarios emphasize recognizing abnormal or potentially erroneous results and selecting an appropriate clinical response. Another major section covers airway management, oxygen therapy, humidity and bronchopulmonary hygiene. Topics include endotracheal-tube placement and cuff problems, suctioning, tracheostomy and laryngectomy care, manual resuscitation, bronchoscopy, chest tubes, nonrebreathing and Venturi masks, nasal cannulas, pulse-dose oxygen, heliox, humidifiers and HMEs. Airway-clearance material includes postural drainage, percussion, coached coughing, high-frequency chest-wall oscillation and modifications for patients with cystic fibrosis, emphysema and other pulmonary disorders. The exam review also tests pulmonary function and respiratory pharmacology. Pulmonary diagnostic concepts include FVC, SVC, FEV1, FEV1/FVC, FEF measurements, DLCO, airway resistance, flow-volume loops, restrictive and obstructive defects, bronchodilator responsiveness and lung volumes such as VC, IC, FRC and TLC. Medication-related questions include albuterol, levalbuterol/Xopenex, tiotropium, acetylcysteine, inhaled corticosteroids, nicotine replacement, aminophylline and metered-dose inhaler education. The document additionally covers neonatal and pediatric respiratory care, including neonatal apnea, oxygen hoods, oxygen blenders, capillary blood sampling, neonatal intubation, gestational-age scenarios, APGAR assessment and manual ventilation of newborns. Pediatric questions address unilateral wheezing and suspected foreign-body aspiration, asthma education and MDI use. Emergency and critical-care scenarios extend to pneumothorax, hemothorax, trauma, hypothermia, diabetic ketoacidosis, cardiac arrhythmias, defibrillation and myasthenic crisis. Relevant students: This resource is particularly relevant to NBRC Therapist Multiple-Choice Examination candidates, respiratory therapy students, respiratory care graduates preparing for credentialing, Certified Respiratory Therapist and Registered Respiratory Therapist candidates, respiratory therapy program students, and learners reviewing mechanical ventilation, ABG interpretation, pulmonary diagnostics, oxygen therapy, airway management and neonatal respiratory care.
