Name one key piece of equipment found in an ambulance.

A defibrillator is a crucial piece of equipment found in an ambulance because it is designed to deliver an electric shock to the heart during life-threatening cardiac arrhythmias, particularly in cases of sudden cardiac arrest. It helps restore normal heart rhythm, significantly increasing the chances of survival for patients experiencing these emergencies. In an ambulance setting, quick access to a defibrillator can be the difference between life and death.

While other items like a stethoscope, surgical kit, and blood pressure monitor are important medical tools, they serve different purposes and may not have the immediate life-saving capability of a defibrillator in critical cardiac situations. The stethoscope is primarily used for listening to heartbeats, a surgical kit is usually not needed in an ambulance setting, and a blood pressure monitor assists in assessing a patient's vital signs. These tools play supportive roles in the overall patient care process, but the defibrillator stands out for its direct impact in emergencies involving cardiac events.
