Emergency Medical Technician (EMT) Intermediate Practice Exam

Which of the following is a sign of respiratory distress?

1. Bradycardia

2. Diaphoresis

3. Hypothermia

4. Increased appetite

The correct answer is: Diaphoresis

Diaphoresis, or excessive sweating, is indeed a sign of respiratory distress. In the context of patients experiencing respiratory difficulties, diaphoresis often occurs due to the body's stress response as it attempts to cope with the increased metabolic demands that come from disrupted breathing. When a person's respiratory system is compromised, such as during an asthma attack, pneumonia, or other airway obstructions, the body may react with sweating as it struggles to maintain oxygenation and balance. The other options do not typically indicate respiratory distress. Bradycardia, which is a slower than normal heart rate, may not be associated directly with respiratory issues. Hypothermia, a dangerously low body temperature, can occur due to various factors that are not directly tied to respiratory problems. Increased appetite is generally not related to respiratory distress; in fact, many individuals may experience a reduced appetite when they are experiencing serious health issues. Therefore, diaphoresis stands out as the most relevant sign in this case.
