The examiner lets you outline your initial plan. Then comes the update: “His blood pressure has fallen, and he is becoming confused.” Your first answer may have been sound. It is no longer enough.
To answer reassessment questions in an emergency medicine viva, state what changed, name the immediate threat, stabilize while gathering focused new information, explain how it alters your differential and plan, then reassess and give the next steps. The examiner is listening for a change in your reasoning—not a longer version of your original answer.
For ABEM candidates, that sequence reflects the board’s published reassessment criteria: obtain information after an unexpected change, analyze its impact, modify care, reassess, describe next steps and consider system factors.
Name the change before naming its cause
Begin with the finding the examiner has just given you. Separate observation from interpretation: “His blood pressure has fallen and his mental status is worsening. I’m concerned he is in shock with impaired perfusion.” This is clearer than jumping straight to a diagnosis that the evidence has not established.
That sentence does two jobs. It shows you heard the new information, and it tells the examiner what risk now comes first. Avoid softening a dangerous change into “I’d keep monitoring him,” or treating it as a reason simply to add more tests. A deteriorating patient needs an immediate response.
Stabilize while you gather the next information
Say what you would do now, not only what you would investigate later. In an unstable patient, repeat a structured assessment of airway, breathing, circulation, disability and exposure; confirm and trend vital signs; call for appropriate help; and start interventions matched to the immediate threats. Use the team so assessment, monitoring and preparations can happen in parallel.
This is not a demand to recite a full resuscitation protocol. The point is to make your priorities audible. “I would send him for imaging” is incomplete if the patient is unstable. Explain how you will support and reassess him while deciding whether he can safely undergo the next investigation. For a broader framework on stating immediate actions, see how to frame immediate management in an oral station.
Show how the new information changes your thinking
Once the immediate threat is addressed, connect the new finding to the differential. A useful sentence is: “This makes me more concerned about X because of Y; I would still consider Z if the next findings support it.” That gives the examiner your reasoning without pretending one new observation proves a diagnosis.
Imagine a 68-year-old being assessed for abdominal pain. He was initially alert and stable; now his blood pressure is 82/54 mmHg, his pulse is 128, and he is pale and confused.
Examiner: What does that change?
Candidate: “He has developed acute hypotension with altered mentation, so I’m concerned about shock and threatened organ perfusion. I would call for resuscitation support, repeat an immediate structured assessment, confirm the observations and begin stabilizing care. While that happens, I’d look for the cause rather than assume the original working diagnosis still explains the whole picture.”
Examiner: What is your differential now?
Candidate: “With abdominal pain and sudden deterioration, significant bleeding is a major concern. I would also consider other causes of shock, including obstructive or cardiogenic causes, and infection if the history and examination support it. I’d use the focused examination, trends and appropriate bedside tests to distinguish these possibilities, and change the treatment plan as the evidence develops.”
The candidate has not listed every cause of hypotension. Instead, the answer shows what moved to the front, what remains possible and how the candidate intends to sort it out. That is the heart of structured clinical reasoning in a viva.
Reassess the patient, not just the answer
A plan to intervene is not the end of the response. Say what you will check after acting: the repeat observations, mental status, perfusion and the patient’s response to treatment. Then state what you will do if the patient improves—and what escalation follows if they do not. Reassessment is a loop: act, check the effect, and adapt.
New information may also rule against your leading explanation. If a bedside finding does not support the cause you suspected, say so. Do not force it to fit. Revise the differential, identify which uncertainty matters next and choose a focused way to resolve it. A negative finding may reduce the likelihood of a diagnosis without excluding it; explain that distinction when it affects your next step.
Finish with a concrete forward plan: which additional assessment or test is now most useful, which specialty or critical-care team you would involve if needed, and whether the patient requires a higher level of care or transfer. Consider practical constraints too: access to blood products, imaging, procedural support or intensive care may change where definitive care can happen. ABEM’s Certifying Exam format guide covers the wider case structure; this article focuses on the spoken reassessment moment.
Avoid the three answers that stall the case
The first is anchoring: repeating the original diagnosis and plan despite a material change. The second is test-listing: naming investigations without saying what danger they address or what you will do while awaiting results. The third is false certainty: claiming that one new sign confirms a cause when it only changes the probability.
A strong answer stays calm and explicit. Name the change. State the threat. Stabilize. Explain what has shifted in your thinking. Reassess and give the next steps. You are not being asked to defend your first plan; you are being asked to show that you can change it when the patient does.
