An example of a sympathomimetic response would be:

Decreased heart rate
Increased salivation
Increased heart rate
Constricted pupils

The correct answer is: Increased heart rate

A sympathomimetic response is one that mimics the effects of the sympathetic nervous system, which is responsible for the body's "fight or flight" reactions. This system is activated during stressful situations and typically results in physiological changes that prepare the body for rapid action. Increased heart rate is a classic example of a sympathetic response. The sympathetic nervous system stimulates the heart to beat faster, enhancing blood flow to the muscles and vital organs, thereby equipping the body to respond to stress or danger more effectively. This increase in heart rate also supports heightened alertness and readiness for physical activity. Other responses that are typically associated with sympathetic activation include dilation of pupils and decreased salivation. When understanding sympathomimetic drugs, it's important to remember that they are often used in scenarios like anaphylaxis or cardiac arrest, where increasing heart rate is beneficial for patient outcomes.
