The nurse would identify which patient condition as a problem of impaired gas exchange secondary to a perfusion problem?

a. Peripheral arterial disease of the lower extremities
b. Chronic obstructive pulmonary disease (COPD)
c. Chronic asthma
d. Severe anemia secondary to chemotherapy

Question 2

The acid-base status of a patient is dependent on normal gas exchange. Which patient would the nurse identify as having an increased risk for the development of respiratory acidosis?

a. Chronic lung disease with increased carbon dioxide retention
b. Acute anxiety, hyperventilation, and decreased carbon dioxide retention
c. Decreased cardiac output with increased serum lactic acid production
d. Gastric drainage with increased removal of gastric acid

Answer to Question 1

ANS: A
Perfusion relates to the ability of the blood to deliver oxygen to the cellular level and return the carbon dioxide to the lung for removal. COPD and asthma are examples of a ventilation problem. Severe anemia is an example of a transport problem of gas exchange.

Answer to Question 2

ANS: A
Respiratory acidosis is caused by an increase in retention of carbon dioxide, regardless of the underlying disease. A decrease in carbon dioxide retention may lead to respiratory alkalosis. An increase in production of lactic acid leads to metabolic acidosis. Removal of an acid (gastric secretions) will lead to a metabolic alkalosis.
