Which of the following is needed to calculate alveolar oxygen tension?

• 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
• C.
A spontaneously breathing patient has the following arterial blood gas results:

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.
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.
Which of the following findings is most closely associated with increased airway resistance?

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.
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.
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

• 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)
• 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
