Which of the following is a sign of respiratory distress?

Shallow breathing is a recognized sign of respiratory distress. This condition occurs when the body struggles to get enough oxygen, causing the individual to take shorter, less effective breaths. In respiratory distress, the respiratory rate may not necessarily be elevated, but the depth of each breath is reduced, leading to inadequate ventilation. This can indicate underlying issues such as obstructive airway conditions, respiratory infections, or other problems that impair normal breathing.

In contrast, the other options do not indicate respiratory distress. A slow heart rate generally suggests bradycardia, which is not directly related to respiratory distress. Increased appetite is typically a sign of health or recovery, not distress. A regular pulse signifies stable cardiovascular function, which is usually not associated with respiratory distress either. Understanding these differences is crucial for identifying respiratory distress effectively and appropriate intervention.
