FP-C Ventilator Management and Respiratory Support

Question 1

What is the recommended lung-protective tidal volume for a mechanically ventilated adult patient during critical care transport?

Accepted Answer

6-8 mL/kg ideal body weight

Answer

10-12 mL/kg actual body weight

Answer

4-5 mL/kg ideal body weight

Answer

8-10 mL/kg actual body weight

Question 2

Which ventilator parameter most directly reflects alveolar plateau pressure and risk of barotrauma?

Accepted Answer

Plateau pressure

Answer

Peak inspiratory pressure

Answer

Mean airway pressure

Answer

PEEP

Question 3

The primary purpose of PEEP in mechanical ventilation is to:

Accepted Answer

Prevent alveolar collapse at end expiration

Answer

Increase tidal volume delivery

Answer

Reduce respiratory rate requirements

Answer

Decrease mean airway pressure

Question 4

During transport, a ventilated patient's SpO2 drops to 88%. The FiO2 is 0.60 and PEEP is 5 cmH2O. What is the most appropriate initial intervention?

Accepted Answer

Increase PEEP to 8-10 cmH2O

Answer

Increase respiratory rate to 20

Answer

Decrease tidal volume to 4 mL/kg

Answer

Switch from volume control to pressure control

Question 5

What I:E ratio is typically used as a starting point for most mechanically ventilated adults?

Accepted Answer

1:2

Answer

1:1

Answer

2:1

Answer

1:3

Question 6

In volume-control ventilation, if the patient's lung compliance decreases, which parameter will change?

Accepted Answer

Peak inspiratory pressure

Answer

Tidal volume

Answer

Respiratory rate

Answer

PEEP

Question 7

Which of the following is the primary advantage of pressure-control ventilation over volume-control ventilation?

Accepted Answer

Limits peak airway pressure and reduces barotrauma risk

Answer

Guaranteed minute ventilation

Answer

Guaranteed tidal volume delivery

Answer

Eliminates the need for sedation
