COMPLETE 450 REAL EXAM QUESTIONS AND
CORRECT DETAILED ANSWERS (VERIFIED
ANSWERS) ALREADY GRADED A+| NBRC TMC EXAM
REVIEW 2025 (BRAND NEW!!)


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 - Correct 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 - Correct 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
Which of the following supplemental oxygen levels is most appropriate?

pg. 1

,2|Page


A. 2 L/min nasal cannula
B. 5 L/min nasal cannula
C. non-rebreathing mask
D. Venturi mask at 30% - Correct Answer - 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 - Correct Answer - 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?
A. reduced SpO2
B. accessory muscle use


pg. 2

,3|Page


C. altered P50
D. increased PetCO2 - Correct Answer - 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 - Correct 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
B. ARDS
C. a pulmonary embolism
D. pneumonia - Correct Answer - C.



pg. 3

, 4|Page


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) - Correct
Answer - D.
Because albuterol is a beta-agonist medication, patients who are taking
beta-blockers should utilize other bronchodilation medication.


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 - Correct 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 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.
