In OPQRST, which component documents when the symptom began?

• A. Quality
• B. Timing
• C. Onset
• D. Severity

Answer: (C)

The main idea here is how we pinpoint when a symptom starts. In the OPQRST framework, the component that captures when the symptom began is onset. It focuses on the moment the symptom started and whether it appeared suddenly or gradually, which helps gauge urgency and plan next steps. For example, chest pain that begins abruptly may suggest a different priority than pain that started slowly over several hours. Quality describes how the symptom feels (for example, sharp or dull), and timing refers to how long the symptom has lasted or how often it recurs after it begins. Severity is about how intense the symptom is. So onset is the best fit for answering “when did this begin?”
