Disconnection from ventilator circuit

Increased lung compliance

Ventilator malfunction

2. True or False: An FiO₂ of 1.0 (100% oxygen) should be used continuously for all mechanically ventilated patients.

True

False

3. True or False: Mechanical ventilation modes include Assist-Control, SIMV, and Pressure Support.

True

False

4. True or False: A high-pressure alarm typically indicates the need to increase tidal volume.

True

False

5. True or False: Increasing respiratory rate will always decrease arterial CO₂ levels.

True

False

6. True or False: PEEP helps prevent alveolar collapse at the end of exhalation.

True

False

7. True or False: In pressure-controlled ventilation, the tidal volume is guaranteed to remain constant with each breath.

True

False

Submit

12. A patient on volume-controlled ventilation has a tidal volume set to 500 mL. Which parameter directly determines minute ventilation?

Respiratory rate only

Tidal volume and respiratory rate

Peak inspiratory pressure

PEEP level

13. When should a patient on mechanical ventilation be considered for weaning?

Within 24 hours of intubation

When underlying cause improves and patient meets readiness criteria

Automatically after 48 hours

Only when FiO₂ reaches 1.0

14. A patient requires mechanical ventilation with an FiO₂ of 0.60. What does this setting indicate?

60% oxygen concentration in delivered gas

6.0 liters per minute flow rate

60 cm H₂O pressure support

60% of normal ventilation

15. In Synchronized Intermittent Mandatory Ventilation (SIMV), what is the primary advantage?

All breaths are completely controlled by the machine

Patient breaths are synchronized with machine breaths

No spontaneous breathing is permitted

Peak pressure is eliminated

16. A ventilator alarm sounds for high peak pressure. Which of these is a likely cause?

Kinked endotracheal tube

Low PEEP setting

Decreased airway resistance

High tidal volume delivery

17. What is the normal range for PEEP in mechanically ventilated patients?

0–5 cm H₂O

5–15 cm H₂O

15–25 cm H₂O

25–35 cm H₂O

18. A patient's arterial CO₂ is 50 mmHg on current ventilator settings. To decrease CO₂, what adjustment would be most effective?

Increase PEEP

Increase respiratory rate or tidal volume

Decrease oxygen concentration

Increase inspiratory time

19. Which ventilator mode provides full mechanical support and is used for patients unable to initiate breaths?

CPAP

Assist-Control

SIMV

Pressure Support

20. A pressure-controlled mode ventilator displays a peak pressure of 25 cm H₂O. What varies with each breath in this mode?

Peak pressure remains constant; tidal volume varies

Tidal volume remains constant; pressure varies

Both pressure and volume remain fixed

Respiratory rate alone determines all parameters

21. What does PEEP stand for in mechanical ventilation?

Positive End-Expiratory Pressure

Peak Expiratory Effort Pressure

Positive Expiration Emergency Protocol

Pressure Equilibrium Exhaust Point
