Emergency Medical Technician (EMT) Intermediate Practice Exam

Epinephrine is classified as a/an:

1. Sympathomimetic

2. Analgesic

3. Anticoagulant

4. Anti-inflammatory

The correct answer is: Sympathomimetic

Epinephrine is classified as a sympathomimetic agent, primarily because it mimics the effects of the sympathetic nervous system. This classification refers to any drug that stimulates the adrenergic receptors in the body, leading to effects such as increased heart rate, bronchial dilation, and elevated blood pressure. These actions are crucial in emergency situations, especially in the treatment of anaphylaxis or severe asthma attacks, where rapid bronchodilation and increased circulation are essential for patient survival. In different contexts, the other classifications mentioned have specific roles: analgesics are used for pain relief, anticoagulants prevent blood clotting, and anti-inflammatory medications reduce inflammation. However, none of these roles accurately describe the primary actions of epinephrine, which primarily works to enhance the body’s fight-or-flight response through stimulation of the adrenergic receptors.
