Increased effort to breathe.

Increased effort to breathe.

• A. Nasal Flaring
• B. Rales
• C. Labored Breathing
• D. Wheezing

Answer: (C)

Increased effort to breathe is called labored breathing. This describes a state where breathing requires more work, often due to airway resistance, reduced lung compliance, or poor oxygenation. You may see visible signs like use of chest and neck muscles, chest retractions, and sometimes nasal flaring as the body struggles to move air. Rales are crackling sounds heard with auscultation from fluid in the airways or alveoli, not a description of how hard the person is working to breathe. Wheezing is a high-pitched whistling sound from narrowed airways, indicating obstruction but not by itself the level of effort. Nasal flaring can accompany respiratory distress but is a sign rather than the overall description of increased work, which is captured best by labored breathing.
