Q

Despite your attempts to coach a conscious young female’s respirations, she continues to hyperventilate with a marked reduction in tidal volume. You should:
Select one:
A. ventilate her at the rate at which she is breathing.
B. restrain her and provide ventilatory assistance.
C. explain to her that you will assist her ventilations.
D. insert a nasopharyngeal airway and give oxygen.

A

C. explain to her that you will assist her ventilations.

143
Q

In contrast to inhalation, exhalation:
Select one:
A. requires muscular effort to effectively expel air from the lungs.
B. occurs when the diaphragm lowers and expels air from the lungs.
C. is a passive process caused by increased intrathoracic pressure.
D. is an active process caused by decreased intrathoracic pressure.

A

C. is a passive process caused by increased intrathoracic pressure.

144
Q

Intrapulmonary shunting occurs when:
Select one:
A. any impairment in circulatory function causes a reduced ability for oxygen and carbon dioxide to diffuse across the alveolar–capillary membrane.
B. the presence of pulmonary surfactant causes a decrease in alveolar surface tension, thus impairing the exchange of gases in the lungs.
C. blood coming from the right side of the heart bypasses nonfunctional alveoli and returns to the left side of the heart in an unoxygenated state.
D. a decrease in respiratory rate and depth causes carbon dioxide accumulation in the alveoli and an overall decrease in blood oxygen levels.

A

C. blood coming from the right side of the heart bypasses nonfunctional alveoli and returns to the left side of the heart in an unoxygenated state.

145
Q

Proper technique for suctioning the oropharynx of an adult patient includes:
Select one:
A. suctioning for up to 1 minute if the patient is well oxygenated.
B. continuously suctioning patients with copious oral secretions.
C. removing large, solid objects with a tonsil-tip suction catheter.
D. suctioning while withdrawing the catheter from the oropharynx.

A

D. suctioning while withdrawing the catheter from the oropharynx.

146
Q 
The diaphragm is innervated by the \_\_\_\_\_\_\_\_\_ nerve, which allows it to contract.
Select one:
A. phrenic
B. hypoglossal
C. vagus
D. vestibulocochlear
A

A. phrenic

147
Q 
The leaf-shaped structure located superior to the larynx is called the:
Select one:

B. cricoid ring.
C. epiglottis.
D. thyroid cartilage.
A

C. epiglottis.

148
Q

The MOST significant complication associated with oropharyngeal suctioning is:
Select one:
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.

A

B. hypoxia due to prolonged suction attempts.

149

C. 3,000
D. 2,000
A

D. 2,000

150
Q 
The process of exchanging oxygen and carbon dioxide between the alveoli and the blood of the capillaries is called:
Select one:
A. pulmonary ventilation.
B. external respiration.
C. alveolar ventilation.
D. cellular metabolism.
A
