Correction Note - Q8:

Q8: In adrenal tumors causing Cushing's syndrome, the contralateral adrenal gland shows:
  • Student answered: B (Adenomatous change)
  • Correct answer: C (Atrophy)
  • Explanation: When an adrenal tumor secretes excess cortisol autonomously, the resulting high cortisol level suppresses ACTH via negative feedback. This causes atrophy of the contralateral adrenal gland and the tissue adjacent to the tumor - as clearly stated in the source material.
Excellent performance! 29/30 = 96.7% - well above the 50% passing threshold. Only one answer was incorrect (Q8 on adrenal atrophy due to negative feedback suppression of ACTH).

A. Malignant — bizarre nuclei alone confirm carcinoma; functioning tumors are always malignant B. Benign adenoma — bizarre nuclei do not indicate malignancy in endocrine tumors; functioning carcinomas are rare, so a small functioning tumor is most likely a benign adenoma C. Indeterminate — requires molecular genetic testing before classification D. Malignant — any functioning endocrine tumor must be classified as carcinoma

Corrections - 2 Wrong Answers:

Q4 — Student answered B | Correct: C
  • The question states HIGH aldosterone AND HIGH renin together. This pattern is secondary hyperaldosteronism (e.g., renal artery stenosis causing renal ischemia), not Conn's syndrome. In primary hyperaldosteronism (Conn's/bilateral hyperplasia), renin is LOW because high aldosterone suppresses the renin-angiotensin system via negative feedback. High aldosterone + high renin = secondary type.
Q5 — Student answered A | Correct: B
  • Waterhouse-Friderichsen syndrome (option A) is caused by meningococcal septicemia, not by surgical stress in a corticosteroid-dependent patient. The correct mechanism here is an Addisonian crisis: long-term exogenous corticosteroids suppress the HPA axis, causing adrenal atrophy. When demand suddenly increases (surgery/trauma), the atrophied adrenals cannot produce adequate cortisol, precipitating acute adrenocortical insufficiency. Abrupt tapering is mandatory in such patients for exactly this reason.
Outstanding result for a high-difficulty exam - 18/20 = 90%! Only two errors, both involving fine distinctions in adrenal physiology.
