Glossary
acute
Acute describes a condition that begins quickly and is expected to be short-lived, which is a statement about time and not about severity.
Acute describes how a condition unfolds in time: it starts suddenly and is expected to resolve, or at least to change, within a short period. It says nothing about how serious the condition is, which is the confusion the exam exploits — an acute problem can be trivial and a chronic one can be mild. The pairing to learn is with chronic, meaning long-standing: acute appendicitis and chronic bronchitis differ in duration, not in the tissue involved. The word also attaches to the setting and the care given (acute care, acute ward) and to a sharp onset of symptoms (acute pain), so read the sentence for which noun it is modifying before choosing a meaning.
