1. 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 B.
Barometric pressure, FiO2, and PaO2 are all included in the formula (BP stands for
barometric pressure)
2. L/min/m2 is the unit of measure for:
A. Systemic vascular resistance
B. Cardiac output
C. Cardiac index
D. Stroke
volume C.
3. 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 Which of the following supplemental oxygen levels is
most appropriate?
A. 2 L/min nasal cannula

B. 5 L/min nasal cannula
C. non-rebreathing mask
D. Venturi mask at
30% B.
A patient who is showing signs of hypoxemia should receive supplemental oxygen. If the
patient is not a COPD patient and the situation is not an emergency, then the proper
supplemental oxygen is an adult therapeutic dose, which is 40% to 55%. Of the options
available only 5 L/min nasal cannula will approach this. Other options are either
insufficient or too much.
4. Left heart failure would be manifested in which of the following values?
A. CVP and mPAP
B. mPAP and wedge pressure
C. MAP and SVR
D. cardiac output and wedge
pressure D.
The function of the left heart, specifically the left ventricle, is best assessed
hemodynamically by looking at those values that precede and come after the left
heart. In this case pulmonary capillary wedge pressure and cardiac output (or cardiac
index) are the values found before and after the left heart.
5. Which of the following findings is most closely associated with increased airway
resistance?
A. reduced SpO2
B. accessory muscle use
C. altered P50

D. increased
PetCO2 B.
Of the options given, use of accessory muscles is most closely associated with an increase
in airway resistance. This is especially true with patients who have asthma or other
types of upper airway inflammation or bronchoconstriction.
6. 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 A.
The lowest inflection point on a pressure-volume ventilator graphic is an indication of
the minimum pressure needed to keep alveoli open.
7. 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
B. ARDS
C. a pulmonary embolism
D. pneumoni
a C.
