Mechanical Ventilation Chapter 5 Test Questions and Answers Graded A+
1. A breath that is patient triggered, pressure targeted, A. Assisted breath
and time cycled is which of the following?
A. Assisted breath
B. Spontaneous breath
C. Breath
D. Mandatory breath
2. A dual control mode provides pressure-limited venti- C. Pressure augmentation
lation with volume delivery targeted for every breath. (Paug)
If the desired volume is not met the ventilator will
volume cycle. This describes which of the following
ventilator modes?
A. Pressure-regulated volume control (PRVC)
B. MMV
C. Pressure augmentation (Paug)
D. Airway pressure release ventilation (APRV)
3. A patient, who is nasally intubated, due to facial C. Intermittent mandato-
surgery, has been successful on her spontaneous ry ventilation (IMV) with
breathing trial. She currently has moderate hypox- pressure support venti-
emia, despite a fractional inspired oxygen (FIO2) of lation (PSV) and posi-
40% and positive end-expiratory pressure (PEEP) of tive end-expiratory pres-
5 cm H2O while on volume-controlled continuous sure (PEEP)
mandatory ventilation (VC-CMV). The most appropri-
ate ventilator mode for this patient is which of the
following?
A. Pressure support ventilation (PSV) with positive
end-expiratory pressure (PEEP)
B. Airway pressure release ventilation (APRV)

C. Intermittent mandatory ventilation (IMV) with pres-
sure support ventilation (PSV) and positive end-expira-
tory pressure (PEEP)
D. Continuous positive airway pressure (CPAP)
4. A homecare patient diagnosed with central sleep ap- B. Noninvasive positive
nea would benefit from which of the following modes pressure ventilation
of ventilation?
A. Pressure support ventilation (PSV)
B. Noninvasive positive pressure ventilation
C. Pressure-controlled intermittent mandatory ventila-
tion (PC-IMV)
D. Continuous positive airway pressure (CPAP)
5. A 68-year-old female admitted for congestive heart D. Noninvasive positive
failure is in respiratory distress and is being seen by pressure ventilation (NIV)
the hospital's medical emergency team in her regular
room. The patient is in obvious respiratory distress
and is immediately placed on a nonrebreather mask.
Physical assessment reveals: pulse 138 and thready;
respiratory rate 30, shallow and labored; temperature
37° C; blood pressure 110/68. Breath sounds are bi-
laterally decreased with coarse crackles on inspiration.
EKG shows normal sinus rhythm with widened cardiac
output (QT) interval and an occasional irregular beat.
No coughing is noted. The arterial blood gas on the
nonrebreather mask is: pH 7.34; PCO2 46 mm Hg; par-
tial pressure of oxygen in the arteries (PaO2) is 52 mm
Hg; oxygen saturation is 86%; bicarbonate (HCO) is 24
mEq/L. The patient is diaphoretic. The most appropri-
ate ventilator mode to manage this patient initially is
