Practice question · Multiple choice
The classic public-health image is a fence at the top of a cliff against an ambulance at the bottom. Which levels of prevention are those, and what does the picture get right?
Hints
- Place each intervention on the timeline relative to the moment of injury.
- Ask whether a health service could sensibly choose one and abandon the other.
Show the answer
B. Fence is primary and ambulance tertiary; they are not rivals
Why
Fencing acts before anyone falls and the ambulance after, primary and tertiary, separated by when they intervene rather than by how serious they are. The image earns its longevity by refusing the false choice: fencing is far cheaper per life, and a service without ambulances is not a service.
