Which of the following could NOT cause a capnography reading to change from 36
torr to 30 torr?

A 2 y/o child with croup has been intubated for 4 days with a 4mm ID uncuffed ETT.
Heated aerosol at an FiO2 of 30% has been delivered to the patient. The physician
asks the RT to evaluate the pt for possible extubation. Which of the following would
most likely indicate that the pt is ready for extubation?
A. Pt is making normal quiet ventilatory efforts
,B. Negative sputum culture and sensitivity has been reported
C. Pt's ABG are within normal range
D. Breath sounds are heard around the tube on auscultation

D. Breath sounds are heard around the tube on auscultation
Measurement of the PD20% is significant for which of the following?
Give this one a try later!
Airway hyperreactivity
A patient recently underwent a thoracotomy and is now receiving IPPB QID. The
patient's inspiratory capacity has diminished over the past several days and the patient
is becoming increasingly SOB. Chest X-ray shows left lower lobe radio density with a
concave upper border. The ET would conclude that the patient has developed:
A. Pleural effusion
B. Atelectasis
C. Pneumothorax
D. Pneumonia
Give this one a try later!
A. Pleural effusion
What is the air-to-oxygen ratio for an air entrainment device delivering 60% oxygen?

A patient has a tracheostomy tube in place. The measured cuff pressure is 28 torr.
Which of the following statements is/are true of this situation?
1. The pressure is appropriate for minimal tracheal occlusion.
2. This pressure will most likely cause arterial occlusion.
3. At this pressure, only lymphatic flow will be affected.
4. The pressure will cause tracheal necrosis if maintained.
Give this one a try later!
2. This pressure will most likely cause arterial occlusion.
4. The pressure will cause tracheal necrosis if maintained.
A post-op thoracotomy pt is receiving incentive spirometry therapy Q2H. Breath
sounds are diminished in the bases of the lungs with scattered crackles. the pt's
inspiratory capacity has decreased over the past 2 days. A chest X-ray indicates thin-
layered basilar densities. Which of the following has most likely occured?
A. Atelectasis
B. Pneumonia
C. Pulmonary Edema
D. Consolidation
Give this one a try later!
A. Atelectasis
, During mechanical ventilation, a patient initiates the breath and then the ventilator
controls the remaining variables for that breath. This describes a/an:
A. Spontaneous breath
B. Assisted breath
C. Mandatory breath
D. Supported breath
Give this one a try later!
B. Assisted breath
The first parameter to measure when a mechanically ventilated patient is placed on
PEEP is:
A. respiratory rate and cardiac rate.
B. compliance.
C. airway resistance.
D. Pa02.
Give this one a try later!
B. compliance.
While instructing a pt prior to a vital capacity maneuver, the RT should direct the pt to:
A. exhale to RV and inhale to IC
B. inhale to TLC then exhale to RV
C. exhale normally then inhale to TLC
D. inhale normally then exhale to FRC
