Textbook Question
Chapter 23, Problem 4CAL
Use the following to answer questions 2–4.
Michelle, age 45, has been smoking for over 30 years. She now is beginning to have trouble breathing. Her physician sent her to have her respiratory function tested. The results showed that she has emphysema, which is characterized by a decreased surface area for alveolar gas exchange.
4. Blood samples were also taken. Which results might be expected for her blood respiratory gases and blood pH?
- a. decrease in PO2, increase in PCO2, decrease in blood pH
- b. decrease in PO2, decrease in PCO2, decrease in blood pH
- c. decrease in PO2, increase in PCO2, increase in blood pH
- d. increase in PO2, decrease in PCO2, increase in blood pH
