FCCS FCCS Respiratory Management 1 — Questions and Answers
Question 1: What tidal volume is recommended for lung-protective ventilation in ARDS patients?
- 10-12 mL/kg predicted body weight
- 6 mL/kg predicted body weight (Correct answer)
- 8 mL/kg predicted body weight
- 14 mL/kg predicted body weight
Correct answer: 6 mL/kg predicted body weight
Lung-protective ventilation in ARDS uses 6 mL/kg predicted body weight to minimize ventilator-induced lung injury.
Question 2: Which ventilator mode delivers a preset tidal volume regardless of airway resistance?
- Pressure Control Ventilation
- Volume Control Ventilation (Correct answer)
- Pressure Support Ventilation
- CPAP
Correct answer: Volume Control Ventilation
Volume Control Ventilation delivers a preset tidal volume by adjusting pressure as needed, regardless of changes in airway resistance or compliance.
Question 3: What is the normal plateau pressure target in mechanically ventilated ARDS patients?
- Less than 30 cmH2O (Correct answer)
- Less than 40 cmH2O
- Less than 20 cmH2O
- Less than 50 cmH2O
Correct answer: Less than 30 cmH2O
Plateau pressure should be kept below 30 cmH2O to reduce the risk of barotrauma in ARDS patients.
Question 4: High-flow nasal cannula (HFNC) therapy can deliver oxygen at flows up to what rate?
- 20 L/min
- 40 L/min
- 60 L/min (Correct answer)
- 80 L/min
Correct answer: 60 L/min
HFNC can deliver heated, humidified oxygen at flow rates up to 60 L/min, providing FiO2 near 1.0.
Question 5: Which parameter best indicates the need for intubation in a patient with respiratory failure?
- SpO2 < 95%
- Increasing work of breathing with fatigue despite therapy (Correct answer)
- PaO2 < 80 mmHg
- Respiratory rate > 20 breaths/min
Correct answer: Increasing work of breathing with fatigue despite therapy
Progressive respiratory muscle fatigue with increasing work of breathing indicates impending respiratory arrest requiring intubation.
Question 6: What does a PaO2/FiO2 ratio less than 200 indicate?
- Mild hypoxemia
- Moderate ARDS
- Severe ARDS (Correct answer)
- Respiratory alkalosis
Correct answer: Severe ARDS
A P/F ratio less than 200 mmHg with bilateral infiltrates and appropriate clinical context defines severe ARDS per the Berlin definition.
