Which one of the following choices is an example of an acute condition?

An acute condition is typically characterized by a sudden onset and a short duration, often requiring immediate medical attention. A fracture is an example of an acute condition because it can occur suddenly due to trauma, such as a fall or an accident, and typically results in immediate pain, swelling, and functional impairment. Treatment is often urgent to prevent further complications, such as misalignment of bones or prolonged pain.

In comparison, an earache may indicate a rather sudden onset of symptoms but can sometimes signal an underlying chronic issue if it recurs frequently. Convulsions, while also acute in nature, are a symptom of an underlying condition rather than a standalone acute ailment. Plantar warts, on the other hand, are typically a chronic condition that develops gradually over time due to a viral infection and do not have an abrupt onset, which distinguishes them from acute conditions. Thus, among the options listed, a fracture is the clearest example of an acute condition.
