In the OPQRST framework, which letter corresponds to the time course of symptoms?

• A. Onset
• B. Time
• C. Provocation
• D. Quality

Answer: (B)

The time component in the OPQRST framework is all about how long the symptoms have been present and how they’ve changed over that period. It asks you to pin down when the symptoms started and to describe their duration and tempo—whether they began suddenly or gradually, and whether they’ve persisted, diminished, worsened, or fluctuated. This helps you gauge how urgent the situation is and what kind of underlying problem you might be dealing with. In practice, you’d compare what’s happening now to earlier moments to understand the course of the illness or injury. The other aspects describe when it started, what triggers or relieves it, and what the symptom feels like, but the time element specifically focuses on duration and progression over time.
