While performing manual ventilation with a self-inflating resuscitator bag through a properly
placed endotracheal tube, a respiratory therapist observes no chest rise. To troubleshoot the
problem, the therapist should
A. check for proper function of the air inlet valve.
B. assure the large bore reservoir tubing is connected.
C. adjust the PEEP valve
D. increase the flowrate. - answer✔✔The correct answer is : A
Explanation :
The scenario suggests that the ET tube is properly placed, therefore the problem must be in the
resuscitator. When the therapist squeezes the device, the air is not being delivered to the patient,
which is why there is no chest rise.
Which of the following pre/post bronchodilator pulmonary function test results is the most
meaningful in suggesting that a bronchodilator is indicated?
A. FEV1.0/FVC % increases by 10%.
B. FEF 200-1200 increases by 17%
C. FEV1 increases by 150 mL
D. FVC increases from 2.5 L to 2.6 L - answer✔✔The correct answer is : B
Explanation :
The two primary considerations in pre-and post-bronchodilator studies are (1) whether flows
increased by at least 12% or more and (2) whether the FEV1 increases by at least 200 mL. The
FEF200-1200, indicating the condition of the large airways, increases by well over 12%, and is
therefore the correct choice.

,A patient with known COPD has the following pre and post bronchodilator studies. Based on this
information, what bronchodilator should the physician prescribe?
D. Albuterol 2.5 mg - answer✔✔The correct answer is : C
Explanation :
Combivent is the best choice because improvement is seen across the board. Vital capacity
improves, FEV1 improves, and FEF 25-75 improves significantly. Albuterol is helpful, but a
greater impact is seen with Combivent.
A therapist would expect to see which of the following capnographic data after providing the
first few manual ventilations on a patient who has been apneic for 4 minutes?
A. low PetCO2
B. low PaCO2
C. unreadable PetCO2
D. high PetCO2 - answer✔✔The correct answer is : A
Explanation :
When the patient has not been breathing for some time and is placed on an end-tidal CO2
monitor (a capnograph), the initial end-tidal CO2 reading would be low. This is because the

, patient has not been breathing and therefore CO2 has not crossed the alveolar capillary
membrane. Only when ventilation is occuring does the CO2 began to cross that membrane, fill
up the alveoli with CO2, and then be shown on an end-tidal CO2 monitor.
A postoperative patient for cardiac surgery is to perform sustained maximum inspiration therapy
with an incentive spirometer. Prior to surgery the patient achieved 1600 mL. The respiratory
therapist should use which of the values as a postoperative, initial goal?
A. 800 mL
B. 1800 mL
C. 1600 mL
D. 1200 mL - answer✔✔The correct answer is : A
Explanation :
An initial goal for incentive spirometry postoperatively is one half of the patient's achievement
prior to surgery. In this case, the patient was able to achieve 1600 mL prior to surgery. The initial
goal should be 800 mL. If the patient is unable to obtain that amount or comes far from that goal,
the goal should be lowered to a volume that is closer to the patient's achievement. This will
incentivize the patient keep trying.
A 12-year-old child is receiving IPPB therapy by mouthpiece. The machine continually fails to
cycle on both the inhalation and exhalation phases. The first step the therapist should take to
resolve the problem is to
A. decrease sensitivity
B. utilize nose clips
C. switch to a mouth seal
D. decrease inspiratory pressure
. - answer✔✔The correct answer is : B
Explanation :
Patients who received IPPB therapy by a mouthpiece can sometimes have a tendency to leak at
the corner of the mouth during a positive pressure breath. The solution for this is to switch to a
