Which of the following is NOT a symptom of respiratory distress?

Bradycardia, which is a slower-than-normal heart rate, is not typically considered a symptom of respiratory distress. In respiratory distress, the body is usually attempting to compensate for inadequate oxygenation or ventilation, which often results in tachycardia (an increased heart rate) as the heart works harder to pump oxygen to the tissues.

In contrast, tachypnea, or rapid breathing, is a common and direct indicator of respiratory distress, as is agitation, which can arise from the body's response to hypoxia or the stress of struggling to breathe. Hemoptysis, or coughing up blood, can also indicate severe respiratory issues and is often associated with conditions that cause respiratory distress.

Thus, the presence of bradycardia does not align with the typical signs of the body responding to respiratory distress, making it the correct answer to identify as not being a symptom of this condition.
