CPR Advanced Airway Management 5

Question 1

A patient is intubated and the capnography waveform shows a rising baseline between breaths. This pattern most likely indicates:

Accepted Answer

Rebreathing of CO2 due to exhausted CO2 absorber or obstructed expiratory valve

Answer

Correct ventilation with high metabolic rate

Answer

Tension pneumothorax

Answer

Right mainstem intubation

Question 2

Answer

(Age + 16) / 4

Answer

(Weight in kg / 10) + 3.5

Answer

Age × 2 + 8

Answer

Puncture the membrane initially

Answer

Inflate the ETT cuff through the incision

Question 6

A PEEP valve is attached to the BVM during ventilation of a patient with severe pulmonary edema. What does PEEP accomplish?

Accepted Answer

Maintains positive airway pressure at end-expiration to recruit alveoli

Answer

Increases inspiratory flow rate to improve oxygenation

Answer

Reduces the tidal volume delivered per breath

Answer

Prevents air trapping in asthmatic patients

Question 7
