CHAPTER 31: Disorders of Ventilation and Gas Exchange
1. A client with a history of emphysema is experiencing hypoxemia after a taxing physical
therapy appointment. Which of the following physiologic phenomena will occur as a
consequence of hypoxemia?
A) Peripheral vasodilation
D) Increased heart rate
Consequences of hypoxemia include peripheral vasoconstriction, hyperventilation, and
increased heart rate. Mild to moderate hypoxemia does not result in cell death and
2. An elderly client who has been restricted to bed by numerous comorbidities for several
weeks has been diagnosed with a large pleural effusion. Which of the following
treatment modalities is most likely to resolve the client's most recent health problem?
B) Supplementary oxygen therapy
C) Administration of corticosteroids
D) Administration of bronchodilators
With large effusions, thoracentesis may be used to remove fluid from the intrapleural
space and allow for reexpansion of the lung.
Page 13. Pleuritic chest pain associated with respiratory movements is usually described as:
Pleuritis is usually unilateral and tends to be localized to the lower and lateral part of the
chest; pain worsens with chest movements, such as deep breathing and coughing that
accentuate pressure changes in the pleural cavity and increase movement of the
inflamed or injured pleural surfaces. Musculoskeletal pain usually is bilateral and may
occur as the result of frequent, forceful coughing. The pain associated with irritation of
the bronchi usually is substernal and dull. Myocardial pain usually is located in the
substernal area and is not affected by respiratory movements.
