You connect an intubated patient to an air-entrainment nebulizer system through a T tube set at 60 with an input flow of 15 L/min. Toward the middle of inspiration, you observe that mist stops exiting from the open end of the T tube.
 
  What does this indicate?
  a. Flow is adequate to meet patient needs.
  b. Patient has a low inspiratory flow rate.
  c. Flowmeter must be calibrated.
  d. Patient is not receiving 60 O2.

Question 2

To ensure the prescribed FiO2 for a patient receiving 65 O2, you apply a closed reservoir deliv-ery system with a one-way expiratory valve. What other component must be included in this sys-tem to ensure a fail-safe operation?
 
  a. Water trap
  b. High-pressure alarm
  c. Emergency inlet valve
  d. Low-pressure alarm

Answer to Question 1

ANS: D
As long as mist can be seen escaping throughout inspiration, flow is adequate to meet the pa-tient's needs, and the delivered FiO2 is ensured.

Answer to Question 2

ANS: C
These systems must be equipped with an emergency inlet valve that allows room air breathing in the event of source gas failure.
