MULTIPLE CHOICE
1.The body’s mechanism for conducting air in and out of the lungs is known as which of the following?
a. External respiration
b. Internal respiration
c. Spontaneous ventilation
d. Mechanical ventilation
ANS:C
The conduction of air in and out of the body is known as ventilation. Since the question asks for the body’s mechanism, this would be spontaneous ventilation. External respiration involves the exchange of oxygen (O 2) and carbon dioxide (CO 2) between the alveoli and the pulmonary capillaries. Internal respiration occurs at the cellular level and involves movement of oxygen from the systemic blood into the cells.
DIF:1REF:pg. 3
2.Which of the following are involved in external respiration?
a. Red blood cells and body cells
b. Scalenes and trapezius muscles
c. Alveoli and pulmonary capillaries
d. External oblique and transverse abdominal muscles
ANS:C
External respiration involves the exchange of oxygen and carbon dioxide (CO2) between the alveoli and the pulmonary capillaries. Internal respiration occurs at the cellular level and involves movement of oxygen from the systemic blood into the cells. Scalene and trapezius muscles are accessory muscles of inspiration. External oblique and transverse abdominal muscles are accessory muscles of expiration. DIF:1REF:pg. 3
3.The graph that shows intrapleural pressure changes during normal spontaneous breathing is depicted by which of the following?
a.
b.
c.
d.
ANS:B
During spontaneous breathing the intrapleural pressure drops from about -5 cm H 2O at end-expiration to about -10 cm H 2O at end-inspiration. The graph depicted for answer B shows that change from -5 cm H 2O to -10 cm H 2O.
DIF:1REF:pg. 4
4.During spontaneous inspiration alveolar pressure (P A) is about: ________________.
a. - 1 cm H2O
b. + 1 cm H2O
c. 0 cm H2O
d. 5 cm H2O
ANS:A
-1 cm H2O is the lowest alveolar pressure will become during normal spontaneous ventilation. During the exhalation of a normal spontaneous breath the alveolar pressure will become +1 cm H2O.
DIF:1REF:pg. 3
5.The pressure required to maintain alveolar inflation is known as which of the following?
a. Transairway pressure (P TA )
b. Transthoracic pressure (P TT)
c. Transrespiratory pressure (P TR) d. Transpulmonary pressure (P L)
ANS:D
The definition of transpulmonary pressure (P L) is the pressure required to maintain alveolar inflation. Transairway pressure (P TA )
is the pressure gradient required to produce airflow in the conducting tubes. Transrespiratory pressure (P TR) is the pressure to inflate the lungs and airways during positive pressure ventilation. Transthoracic pressure (P TT) represents the pressure required to expand or contract the lungs and the chest wall at the
same time.
DIF:1REF:pg. 3
6.Calculate the pressure needed to overcome airway resistance during positive pressure ventilation when the proximal airway pressure (PAw) is 35 cm H2O and the alveolar pressure (P A) is 5 cm H2O.
a. 7 cm H2O
b. 30 cm H2O
c. 40 cm H2O
d. 175 cm H2O
ANS:B
The transairway pressure (P TA ) is used to calculate the pressure required to overcome airway resistance during mechanical ventilation. This formula is P TA = Paw - PA.
DIF:2REF:pg. 3
7.The term used to describe the tendency of a structure to return to
its original form after being stretched or acted on by an outside force is which of the following?
a. Elastance
b. Compliance
c. Viscous resistance
d. Distending pressure
