Introduction:The Therapist Multiple-Choice and Clinical Simulation
Examination evaluates entry-level and advanced cognitive proficiencies
expected of registered respiratory therapists. This comprehensive
assessment measures foundational knowledge, applied clinical
reasoning, and critical decision-making across diverse cardiorespiratory
care scenarios. Candidates must demonstrate competence in patient
evaluation, diagnostic interpretation, mechanical ventilator
management, and emergency response. The structure incorporates
both multiple-choice items and clinical case simulations designed to
assess real-world application, safety protocols, and evidence-based
therapeutic interventions required in modern clinical healthcare
environments.
Section One: Questions 1–100
A 58-year-old male with a history of severe chronic obstructive
pulmonary disease (COPD) is admitted to the emergency
department presenting with acute respiratory distress, confusion,
and peripheral cyanosis. Arterial blood gas analysis on room air
reveals: pH 7.28, PaCO2 72 mm Hg, PaO2 45 mm Hg, HCO3 34
mEq/L. Which of the following oxygen delivery devices is most
appropriate to initiate controlled oxygen therapy?
A. Non-rebreather mask at 15 L/min
B. Simple oxygen mask at 8 L/min
C. Nasal cannula at 2 L/min
🟢 D. Venturi mask delivering 28% oxygen
,🔴 Explanation: Patients with chronic hypercapnia rely on hypoxic drive
and are at risk of acute carbon dioxide narcosis and worsening
respiratory acidosis if given excessive supplemental oxygen. A Venturi
mask provides precise, controlled FiO2 delivery (such as 28%),
mitigating the risk of removing their hypoxic drive while safely improving
oxygenation.
During the setup of a volume-controlled continuous mandatory
ventilation (VC-CMV) mode for an adult patient with acute
respiratory distress syndrome (ARDS), the respiratory therapist
aims to minimize ventilator-induced lung injury (VILI). Which of
the following initial tidal volume settings is clinically
recommended?
A. 4 mL/kg of predicted body weight
B. 6 mL/kg of predicted body weight
C. 10 mL/kg of predicted body weight
🟢 D. 8 mL/kg of predicted body weight
🔴 Explanation: Lung-protective ventilation strategies for ARDS
recommend targeting a low tidal volume of 6 mL/kg of predicted body
weight (with a permissible range starting around 6 mL/kg, though up to
8 mL/kg is sometimes utilized depending on plateau pressures) to
prevent alveolar overdistention and volutrauma. Wait, let's verify
standard guidelines: ARDSNet protocol specifies 4 to 8 mL/kg PBW,
starting at 6 mL/kg. Let's look at option B vs D. Standard protective
ventilation targets 6 mL/kg PBW. Let's make sure B is the intended
correct answer for low tidal volume. Let's adjust option B as the correct
answer.
Let's restate Question 2 with B as the correct answer:
2. During the setup of a volume-controlled continuous mandatory
ventilation (VC-CMV) mode for an adult patient with acute respiratory
distress syndrome (ARDS), the respiratory therapist aims to minimize
ventilator-induced lung injury (VILI). Which of the following initial tidal
volume settings is clinically recommended?
A. 10 mL/kg of predicted body weight
🟢 B. 6 mL/kg of predicted body weight
,C. 8 mL/kg of predicted body weight
D. 12 mL/kg of predicted body weight
🔴 Explanation: Lung-protective ventilation guidelines for acute
respiratory distress syndrome mandate setting low tidal volumes
starting at 6 mL/kg of predicted body weight to limit plateau pressures
below 30 cm H2O and reduce volutrauma and barotrauma risks.
A respiratory therapist is evaluating a patient receiving
mechanical ventilation and observes a sudden increase in peak
inspiratory pressure (PIP) while the plateau pressure (Pplat)
remains unchanged. Which of the following complications is most
consistent with these findings?
A. Decreased lung compliance
B. Alveolar consolidation
🟢 C. Increased airway resistance
D. Right mainstem intubation
🔴 Explanation: An elevated peak inspiratory pressure with a normal
plateau pressure indicates an increase in airway resistance, which can
be caused by bronchospasm, mucosal edema, accumulated secretions
in the artificial airway, or kinking of the endotracheal tube.
A patient with myasthenic crisis is being monitored in the
pulmonary step-down unit. Serial bedside pulmonary function
testing indicates a vital capacity (VC) of 12 mL/kg and a negative
inspiratory force (NIF) of -18 cm H2O. What is the most
appropriate immediate clinical action?
A. Continue close serial monitoring every 4 hours
B. Administer a dose of edrophonium to assess muscle strength
🟢 C. Initiate elective endotracheal intubation and mechanical
ventilation
D. Apply non-invasive positive pressure ventilation (NIPPV) with high
IPAP
🔴 Explanation: A vital capacity falling below 15 mL/kg and a negative
inspiratory force less negative than -20 cm H2O indicate impending
ventilatory failure and severe diaphragmatic weakness in
, neuromuscular disease, requiring immediate airway protection and
invasive mechanical ventilation.
Which of the following federal agencies establishes regulations
regarding occupational safety, hazardous materials handling, and
medical gas storage standards in healthcare facilities?
A. Food and Drug Administration (FDA)
B. Environmental Protection Agency (EPA)
🟢 C. Occupational Safety and Health Administration (OSHA)
D. Centers for Medicare & Medicaid Services (CMS)
🔴 Explanation: The Occupational Safety and Health Administration
(OSHA) sets and enforces standards to ensure safe and healthful
working conditions, which include regulations governing compressed
medical gases, hazardous chemical exposure, and workplace safety in
clinical facilities.
A premature infant born at 28 weeks gestation develops
respiratory distress syndrome (RDS) and is placed on mechanical
ventilation. Chest radiography reveals a "ground-glass"
appearance and air bronchograms. Which of the following
therapeutic interventions is indicated to address the primary
underlying pathophysiology?
A. Administration of systemic corticosteroids
B. Inhaled nitric oxide therapy
🟢 C. Administration of exogenous surfactant via endotracheal tube
D. High-frequency jet ventilation with high peak pressures
🔴 Explanation: Neonatal respiratory distress syndrome is caused by a
primary deficiency of pulmonary surfactant, leading to alveolar collapse
and decreased compliance. Administration of exogenous surfactant
directly replaces the missing substance, reducing surface tension and
improving gas exchange.
While reviewing a patient's medical record, a respiratory therapist
notes an order to withhold a specific diagnostic treatment
because the patient is legally competent and has refused
