In the Assessment, the differential diagnosis should be listed in order of what?

• A. Chronology
• B. Likelihood
• C. Severity
• D. Patient preference

Answer: (B)

The key idea is to rank possible causes by how likely they are given the patient’s history, exam, and initial findings. Listing the differential in order of likelihood helps you focus your questions, tests, and next steps on the most probable conditions first, making the assessment efficient and practical. It also keeps you mindful of dangerous but plausible possibilities so you won’t miss a critical diagnosis, especially if red flags appear. Other ways you might think about organizing it, like by chronology (when symptoms started), by severity (how bad the outcomes could be), or by patient preference, don’t best guide the early diagnostic process. Chronology can help with specific patterns, severity matters for urgency but not the overall prioritization, and patient preference influences management more than the initial diagnostic ranking.
