A physician asks a patient, "how long has your issue been going on". The patient's answer is referred to as which of the following? Chief complaint Past medical history History of present illness Review of systems

## Step 1<br />The question is asking for the term that refers to the patient's response to the physician's question, "how long has your issue been going on". This question is part of the patient's medical history, specifically the "History of Present Illness" (HPI). <br /><br />## Step 2<br />The HPI is a detailed, chronological description of the problems prompting the patient's visit. It includes the onset, location, duration, character, radiating/associated factors, context of symptoms, and modifying factors of the symptoms. <br /><br />## Step 3<br />The other options, "Chief complaint", "Past medical history", and "Review of systems", are also parts of the medical history but they do not specifically refer to the patient's response to the physician's question about the duration of the issue.
