#1
Which of the following is a common indication for initiating mechanical ventilation?
Hypoxemia
ExplanationHypoxemia is a common reason to start mechanical ventilation to improve oxygenation.
#2
What is the primary goal of mechanical ventilation?
To decrease respiratory effort
ExplanationMechanical ventilation aims to reduce the work of breathing for the patient.
#3
What is the purpose of FiO2 in mechanical ventilation?
To deliver supplemental oxygen
ExplanationFiO2 ensures adequate oxygen delivery during mechanical ventilation.
#4
Which of the following is a potential complication of mechanical ventilation?
Hypotension
ExplanationHypotension may occur as a complication of mechanical ventilation.
#5
What is the term for the process of removing carbon dioxide from the bloodstream using mechanical ventilation?
Ventilation
ExplanationVentilation involves eliminating carbon dioxide from the blood during mechanical ventilation.
#6
Which mode of mechanical ventilation allows spontaneous breathing efforts between mandatory breaths?
Synchronized Intermittent Mandatory Ventilation (SIMV)
ExplanationSIMV permits patient-initiated breaths alongside mandatory ventilation cycles.
#7
In mechanical ventilation, PEEP stands for:
Positive End-Expiratory Pressure
ExplanationPEEP helps maintain lung volumes during mechanical ventilation by preventing alveolar collapse.
#8
In pressure-controlled ventilation (PCV), which parameter is set and maintained by the ventilator?
Peak inspiratory pressure
ExplanationPCV maintains a set peak inspiratory pressure during ventilation.
#9
What is the primary advantage of bilevel positive airway pressure (BiPAP) ventilation over conventional mechanical ventilation?
Improved patient comfort
ExplanationBiPAP enhances patient comfort compared to traditional ventilation methods.
#10
In volume-controlled ventilation (VCV), which parameter is set and maintained by the ventilator?
Tidal volume
ExplanationVCV regulates and sustains a preset tidal volume during ventilation.
#11
Which of the following ventilator parameters represents the amount of air delivered with each breath?
Tidal Volume (Vt)
ExplanationTidal volume is the volume of air delivered with each breath during mechanical ventilation.
#12
Which ventilator mode is commonly used in patients with neuromuscular diseases to support spontaneous breathing?
Airway Pressure Release Ventilation (APRV)
ExplanationAPRV is often used to aid spontaneous breathing in patients with neuromuscular conditions.
#13
Which of the following is a potential complication of barotrauma in mechanically ventilated patients?
Pneumothorax
ExplanationBarotrauma in ventilated patients may lead to a pneumothorax as a complication.
#14
Which ventilator mode allows the patient to breathe spontaneously with a constant positive pressure applied at the airway throughout the respiratory cycle?
Continuous Positive Airway Pressure (CPAP)
ExplanationCPAP maintains a constant positive airway pressure throughout the respiratory cycle, aiding spontaneous breathing.
#15
What is the primary advantage of pressure-controlled ventilation (PCV) over volume-controlled ventilation (VCV)?
PCV reduces the risk of barotrauma.
ExplanationPCV decreases the likelihood of barotrauma by limiting airway pressure.
