For a patient receiving volume-controlled mechanical
ventilation, the lower inflection point on a pressure-volume
loop can best be described as:
A. amount of pressure required to keep the alveoli and
small airways open
B. optimal PEEP
C. minimal PEEP
D. upper limit of residual volume - Answer-A.
The lowest inflection point on a pressure-volume ventilator
graphic is an indication of the minimum pressure needed
to keep alveoli open.
The results of a V/Q scan shows poor perfusion with
adequate ventilation. A chest radiograph shows a wedge-
shaped infiltrate over the right lung field. The patient most
likely has
A. fluid overload
,2|Page
B. ARDS
C. a pulmonary embolism
D. pneumonia - Answer-C.
A VQ scan that shows poor perfusion but adequate
ventilation is most closely associated with a pulmonary
embolism. Supportive data is found in the radiological
report of wedge-shaped infiltrates.
The respiratory therapist notes in the medical record of a
65-year-old male that the patient is ordered to receive
bronchodilator therapy with Albuterol. The therapist also
notes the patient is receiving beta-blocker medication. The
therapist should recommend
A. Administer Dexamethasone (Decadron) in place of
Albuterol
B. Add Xopenex to the bronchodilator regimen
C. Replace Albuterol with Beclamethasone (Beclovent)
D. Switch from Albuterol to ipratropium bromide (Atrovent)
- Answer-D.
Because albuterol is a beta-agonist medication, patients
who are taking beta-blockers should utilize other
bronchodilation medication.

A hospital has an extremely low incidence of ventilator-
associated pneumonia. To which of the following reasons
may this be attributed?
A. periodic discontinuation of sedation
B. use of respiratory precautions with the population
C. diversion of infectious patients to other facilities
D. broad use of prophylactic antibiotics - Answer-A.
The incidence of ventilator-associated pneumonia, or VAP,
is lowered by using a closed system suction catheter,
periodically discontinuing sedation, keeping the patient
and semi-Fowler's position, and proper handwashing
among caregivers. All are correct.
A pressure-volume loop ventilator graphic shows no rise in
pressure for the first 200 mL of delivered volume. The
therapist should
A. increase inspiratory flow rate
B. increase PEEP
C. decrease tidal volume
D. decrease inspiratory flow rate - Answer-B.
In this question the description of the pressure volume
loop would indicate a flat bottom as manifested by no rise
in pressure with the first 200 mL of delivered volume. We
, 4|Page
call this a "flat football". The solution is to increase PEEP
to a level that the pressure begins to rise immediately as
volume is introduced.
Which of the following is needed to calculate alveolar
oxygen tension?
A. VD/VT, PAO2
B. BP and FiO2
C. PetCO2 and PaO2
D. QS/QT, deadspace - Answer-B.
Barometric pressure, FiO2, and PaO2 are all included in
the formula (BP stands for barometric pressure)
L/min/m2 is the unit of measure for:
A. Systemic vascular resistance
B. Cardiac output
C. Cardiac index
D. Stroke volume - Answer-C.
A spontaneously breathing patient has the following
arterial blood gas results:
pH 7.38 PaCO2 42 mmHgPaO2 76 mmHgHCO3- 24
mEq/LBE 0 mEq/L
