Question 1

An apnea alarm may be activated by which of the following?

Accepted Answer

A)  Secretions 
B)  Auto PEEP 
C)  Loss of PEEP 
D)  Active inhalation 
A)  Secretions 
B)  Auto PEEP 
C)  Loss of PEEP 
D)  Active inhalation

Question 2

A patient with a past medical history of COPD was placed on a ventilator after upper abdominal surgery for a serious wound infection.Although the patient was medically stable,a tracheostomy was performed 2 weeks later because the patient was unable to be weaned from the ventilator.The patient is on VC-CMV,rate = 12,VT = 700 mL,FIO2 = 40%,PEEP = 5 cm H2O,with an HME.The respiratory therapist notes that the patient is assisting at a rate of 18 and has bilaterally decreased breath sounds in the bases.The respiratory therapist suctions a moderate amount of very thick,tenacious yellow sputum from the tracheostomy tube.What action should the respiratory therapist take?

Accepted Answer

A)  The HME should be replaced with an active heated humidifier system. 
B)  No action is necessary,because there seems to be no patient problem. 
C)  The patient should be suctioned on a regular schedule instead of when needed. 
D)  PEEP and the FIO2 should be increased,and diuretic and positive inotropic agents should be administered.

Question 3

The respiratory therapist enters the room of an intubated and mechanically ventilated patient to find the high pressure,low exhaled volume,and low VE alarms active.This situation could be caused by which of the following?

Accepted Answer

A)  Improper flow rate and flow pattern. 
B)  Migration of the ET into the upper airway. 
C)  The patient is out of synchrony with the ventilator. 
D)  The ventilator has an internal malfunction. 
A)  Improper flow rate and flow pattern. 
B)  Migration of the ET into the upper airway. 
C)  The patient is out of synchrony with the ventilator. 
D)  The ventilator has an internal malfunction.

Question 4

The respiratory therapist is performing a patient-ventilator system check on a patient who was in a motor vehicle accident 2 days earlier.The therapist gathers the following information from the flow sheet:   Which condition most likely has produced the changes reflected in these data?

Accepted Answer

A)  Bronchospasm 
B)  Abdominal distention 
C)  Secretion retention 
D)  Mucosal edema
