Correct answer: D — Use preoperative alpha blockade and volume expansion, adding beta blockade later
Explanation lettering: C = shown as B · B = shown as C · E = shown as D · D = shown as E
E is correct. UK Society for Endocrinology guidance starts alpha blockade at least 14 days preoperatively; phenoxybenzamine often begins 10 mg once or twice daily and is titrated, with salt and fluid expansion. A beta blocker may be added for tachycardia only after effective alpha blockade, typically no earlier than four days, to avoid unopposed vasoconstriction. Same-day preparation, sodium restriction, beta-first therapy and unprepared surgery risk crisis.
