Endocrinology Masterclass: 15 High-Yield MCQs

15 high-yield, single-best-response MCQs covering endocrinology end to end — Graves TRAb diagnosis with timed carbimazole, thyroid storm thionamide-before-iodide sequencing, hypothyroidism low-start levothyroxine in cardiac disease, myxoedema coma steroids-before-T4 cover, amiodarone type 1 versus type 2 disease, hypercalcaemia PTH split with fluids-then-bisphosphonate, hypocalcaemia IV gluconate under ECG watch, osteoporosis weekly alendronate with denosumab never stopped cold, adrenal crisis immediate hydrocortisone, Cushing 1-mg DST screening before ACTH, phaeochromocytoma alpha-blockade before surgery, SIADH fluid restriction versus salt-wasting saline, acromegaly IGF-1 with surgery first-line, PCOS Rotterdam with letrozole since 2023, and insulinoma Whipple with 72-hour fast then localisation. Every question is checked against a named primary source — NICE, ATA, Endocrine Society, NOGG, FDA labels — and printed on screen beneath the rationale, so you can verify the claim rather than take it on trust. Where teaching has moved under the author, this video teaches the current guideline and names the retired version: clomiphene-first ovulation induction (pre-2023), iodide-first storm therapy, beta-blocker-first phaeochromocytoma care, and denosumab stopped without a switch plan. Pause on each question, lock your answer before the 6-second timer ends, then read the trap rationale, its source, and the "why the other three are wrong" mini-lesson.
