BONUS (from the final, incomplete case in the source packet): A 75-year-old male presents for routine fillings. History: hypertension, prior transient ischemic attacks, hypercholesterolemia; he ran out of his warfarin 2 days ago. Current medications: losartan, warfarin, atorvastatin, daily aspirin 81mg. Today's blood pressure is 208/90. What is the most appropriate course of action?

A systolic blood pressure of 208 mmHg falls within the hypertensive crisis range (systolic ≥180 mmHg), which on its own is a recognized indication to defer elective dental treatment and seek prompt medical evaluation, regardless of the diastolic value. This is further complicated by the patient having stopped his warfarin 2 days ago (creating uncertain anticoagulation status) and a history of TIA — all reasons to prioritize medical management over proceeding with elective restorative treatment today. (Note: the original source document was cut off at this point before showing the actual exam question and answer choices for this case — this question was constructed from the available case information to give you a complete, standalone item to practice on, and may not exactly match the original exam's intended question.)
