A nurse is analyzing arterial blood gas results for a client diagnosed with chronic obstructive pulmonary disease (COPD). What abnormal finding should the nurse anticipate?
Increased carbon dioxide.
Increased pH.
Decreased alveolar function.
Increased arterial oxygen.
The Correct Answer is A
Choice A rationale
In a client diagnosed with chronic obstructive pulmonary disease (COPD), an arterial blood gas (ABG) test would typically show an increased level of carbon dioxide (PaCO2)56. This is because COPD affects the ability of the lungs to expel carbon dioxide, leading to its buildup in the blood.
Choice B rationale
An increased pH is not typically seen in COPD. In fact, due to the increased carbon dioxide (which is acidic), the pH may be lower, indicating respiratory acidosis.
Choice C rationale
Decreased alveolar function is a characteristic of COPD, but it is not something that would be directly measured in an ABG test.
Choice D rationale
An increased arterial oxygen (PaO2) is not typically seen in COPD. In fact, due to the impaired gas exchange, PaO2 may be lower.

Correct Answer is C
Explanation
Choice A rationale
A pH of 7.55, PaCO2 of 30 mm Hg, PaO2 of 80 mm Hg, and HCO3 of 24 mEq/L would indicate respiratory alkalosis, which is not typically associated with progressive COPD67.
Choice B rationale
A pH of 7.40, PaCO2 of 40 mm Hg, PaO2 of 94 mm Hg, and HCO3 of 22 mEq/L represent normal ABG values.
Choice C rationale
A pH of 7.30, PaCO2 of 60 mm Hg, PaO2 of 70 mm Hg, and HCO3 of 30 mEq/L are indicative of respiratory acidosis with metabolic compensation, which is commonly seen in patients with progressive COPD67.
Choice D rationale
A pH of 7.38, PaCO2 of 45 mm Hg, PaO2 of 88 mm Hg, and HCO3 of 26 mEq/L would indicate a slight respiratory acidosis, which is not typically associated with progressive COPD67.
Correct Answer is B
Explanation
Choice A rationale
A chocolate milkshake may be soothing, but it is not the best choice for a patient with bacterial pharyngitis due to its high sugar content, which can promote bacterial growth.
Choice B rationale
Chicken noodle soup is a good choice as it is soothing, easy to swallow, and provides necessary nutrients.
Choice C rationale
Vanilla ice cream, while soothing, is not the best choice due to its high sugar content.
Choice D rationale
Fruit-flavored popsicles, while soothing, are not the best choice due to their high sugar content.
