A client experiencing hypercarbia would exhibit which pattern of breathing?

• A. Hypoventilation
• B. Hyperventilation
• C. Apnea
• D. Cheyne-Stokes

Answer: (A)

Elevated carbon dioxide in the blood comes from not removing enough CO2 through breathing. The breathing pattern that fits this is hypoventilation—breathing that is too shallow or too slow to effectively eliminate CO2. When ventilation is reduced, CO2 builds up, leading to hypercarbia and often a tendency toward respiratory acidosis. Hyperventilation would lower CO2, not raise it; apnea is a complete stop in breathing; Cheyne-Stokes is a specific cyclical pattern with alternating periods of deep and shallow breathing and pauses, not the typical response to just increased CO2.
