Question 1

Which ventilator waveform finding is most consistent with auto-PEEP (intrinsic PEEP)?

Accepted Answer

Expiratory flow that does not return to zero before the next breath

Answer

Auto-PEEP occurs when expiratory flow is still present when the next breath begins, indicating incomplete exhalation.

Question 2

A patient with a tracheostomy tube has a plugged inner cannula causing acute respiratory distress. What is the FIRST action the therapist should take?

Accepted Answer

Remove and replace the inner cannula

Answer

Removing and replacing (or cleaning) the inner cannula immediately relieves the obstruction caused by secretion plugging.

Question 3

What is the recommended maximum suction pressure for an adult patient during endotracheal suctioning?

Accepted Answer

-100 to -150 mmHg

Answer

AARC guidelines recommend suctioning pressure of -100 to -150 mmHg for adults to effectively clear secretions while minimizing trauma.

Question 4

Which condition is MOST likely to cause a normal chest X-ray in a patient with severe hypoxemia?

Accepted Answer

Pulmonary embolism

Answer

Pulmonary embolism obstructs blood flow without direct parenchymal changes, often leaving the CXR normal or near-normal despite severe hypoxemia.

Question 5

When setting up a 6-minute walk test (6MWT), which criterion would DISQUALIFY a patient from completing the test?

Accepted Answer

Unstable angina or recent MI within 1 month
