Colorado CNA Practice Exam

Which of the following would NOT be considered an abnormal pattern of respiration?

1. Cheyne-Stokes respiration

2. Kussmaul breathing

3. Orthopnea

4. Regular breathing

The correct answer is: Cheyne-Stokes respiration

The correct choice is regular breathing, as it is the only option that indicates a normal pattern of respiration. Regular breathing refers to a consistent and even rhythm of inhalation and exhalation, which is expected in healthy individuals at rest. In contrast, Cheyne-Stokes respiration, Kussmaul breathing, and orthopnea are all considered abnormal patterns. Cheyne-Stokes is characterized by a cyclical pattern of gradual increases and decreases in breathing, followed by periods of apnea. Kussmaul breathing involves deep, rapid breaths and is often associated with conditions like metabolic acidosis. Orthopnea refers to difficulty breathing that occurs when lying flat, typically alleviated by sitting up. Each of these patterns indicates underlying health issues or respiratory distress, marking them as abnormal compared to regular breathing.
