B. flow rate is set at 6 L/min.
C. reservoir bag is fully inflated.
D. patient has reduced tidal volume..
Answer: C. reservoir bag is fully inflated.


◉ Which of the following statements regarding normal gas exchange
in the lungs is correct?
A. The oxygen content in the alveoli is highest during the exhalation
phase.
B. Oxygen and carbon dioxide diffuse across the alveolar walls and
capillaries.
C. The actual exchange of oxygen and carbon dioxide occurs in the
capillaries.
D. Blood that returns to the lungs from the body has a low carbon
dioxide content..

, Answer: B. Oxygen and carbon dioxide diffuse across the alveolar
walls and capillaries.


◉ The MOST significant complication associated with oropharyngeal
suctioning is:
A. oral abrasions from vigorous suctioning.
B. hypoxia due to prolonged suction attempts
.C. clogging of the catheter with thick secretions.
D. vomiting from stimulating the anterior airway..
Answer: B. hypoxia due to prolonged suction attempts


◉ The physical act of moving air into and out of the lungs is called:
A. diffusion.
B. ventilation.
C. respiration.
D. oxygenation..
Answer: B. ventilation.


◉ How does CPAP improve oxygenation and ventilation in patients
with certain respiratory problems?
A. It forces the alveoli open and pushes more oxygen across the
alveolar membrane.
