Lesson 25: Substance Misuse and Abuse
You Are the
Emergency Medical Responder
Your emergency medical services (EMS) unit is
summoned to a residence on a report of an
unconscious person. When you arrive and size-up
the scene, you discover an older couple. The wife is
distraught and says that her husband had been
drinking alcoholic beverages heavily earlier in the
day. Shortly after taking his prescribed Valium®, she
says he became drowsy and incoherent, and then
collapsed. Unable to get him to respond, she called
9-1-1. On assessing the patient, you find that he is
unresponsive, his breathing is shallow and slow, his
heart rate is slow and his pulse is weak.
