If the respiratory therapist notices the reservoir bag on a nonrebreather mask is failing to partially
collapse with each breath, the therapist should
A. tighten the elastic straps on the mask
B. obtain a new nonrebreather mask
C. increase oxygen flow to the reservoir
D. remove the one-way valve disk A. tighten the elastic straps on the mask
For a patient who is breathing oxygen through a non-rebreather mask, failing to cause a partial
collapse of the reservoir with each breath is an indication that either the mask is not tight enough
or that the flow to the mask is excessive. It is most likely that the mask requires tightening,
which can be done by pulling on the elastic straps.
A patient is found to have a rhythm on the ECG monitor consistent with asystole. Which of the
following is the best initial action of the respiratory therapist?
A. Defibrillate at 360 joules, unsynchronized
B. Confirm in a second lead

C. Begin chest compressions
D. Defibrillate at 50 joules, synchronized B. Confirm in a second lead
This rhythm is called asystole. When observed, prior to starting chest compressions, the rhythm
should be confirmed in his second lead.
Within 5 minutes of oral extubation, the patient demonstrates mild inspiratory and expiratory
stridor, some accessory muscle use, and an SpO2 of 92% on 40% air-entrainment mask. The
therapist should recommend
A. benzocaine spray to the oropharynx
B. aerosolized racemic epinephrine
C. heated bland aerosol
D. reintubation B. aerosolized racemic epinephrine
The presence of inspiratory and expiratory stridor can be addressed by the therapist through the
administration of racemic epinephrine. This medication is an alpha-1 type drug that constricts
tissue. However, this can only be used when the level of stridor is considered mild or moderate.
In the presence of severe or marked stridor, immediate establishment of an airway is preferred.

A respiratory therapist is alerted by a ventilator alarm of a 62-year-old patient with COPD who
was intubated for bacterial pneumonia. Upon arrival, the therapist notes the activation of the low
PEEP alarm. For which of the following should the therapist investigate to determine the source
of the alarm?
A. pinched inspiratory limb of the circuit
B. occlusion of the ET tube
C. reduced ET tube cuff pressure
D. lung tissue perforation C. reduced ET tube cuff pressure
A low PEEP alarm occurs when there is a continuous leak in the system, disallowing PEEP
pressure to accumulate and hold steady. Of the options given, a reduction in ET tube cuff
pressure could be the only likely cause. A pinched circuit or an occlusion of the ET tube would
trigger a high-pressure alarm. A perforation in the lung tissue could indeed cause a low pressure,
low volume, or low PEEP alarm but it is very unlikely.
A patient is engaged in a smoking cessation program. During a routine visit to the counseling
clinic, the patient describes shortness of breath (dyspnea) after every meal. Which of the

D. increase complex carbohydrate consumption between meals B. eat small meals more
frequently, avoid too many carbohydrates

smaller meals more frequently and to avoid excessive consumption of carbohydrates, which
produce carbon dioxide and place a greater ventilatory load on the patient.
The best way to determine the accuracy of a vane respirometer is a
A. Geizler tube ionizer
B. Douglas bag
C. galvanic analyzer
D. 1.5-liter calibrated syringe D. 1.5-liter calibrated syringe
