Long Case Viva Defence
Opening statement
"This patient presents with a problem best framed as Beta Blocker AND Calcium Channel Blocker Toxicity. My priorities are to identify red flags, confirm the mechanism with purposeful investigations, start a sequenced management plan, and integrate multimorbidity and follow-up." [1] [2]
Examiner questions
Q1: "What makes this urgent?" [1]
"I look for threats to airway, perfusion, neurology, metabolism, infection or bleeding, and I escalate those before elective work-up." [1] [2]
Q2: "What is your first investigation package?" [2]
"I order tests that change management now, not a scattergun panel." [1] [2]
Q3: "Walk me through treatment." [1]
"Stabilise, treat the mechanism, prevent complications, and plan monitoring." [1] [2] [3]
Q4: "What is the classic trap?" [2]
"Treating a label without confirming the discriminating mechanism, or delaying escalation." [1] [2]
Short case
Counsel the patient on the plan, risks and warning symptoms in plain language. [1] [2]
