الإجابة: C. Dexamethasone suppression test, aldosterone/renin ratio and 24-h urinary metanephrines
Every incidentaloma is screened with a dexamethasone suppression test (Cushing) and metanephrines (pheochromocytoma); because she is hypertensive (150/95), an aldosterone/renin ratio is added for primary aldosteronism.
- TSH is not part of the adrenal mass work-up (option D); options A and B each omit a required test.

A
ليش غلط
Misses the Cushing screen: every adrenal incidentaloma is screened for pheochromocytoma and Cushing syndrome, so a dexamethasone suppression test is needed.

Misses the pheochromocytoma screen (metanephrines): every adrenal incidentaloma is screened for pheochromocytoma and Cushing syndrome.

C
ليش صح
All incidentalomas get the pheochromocytoma and Cushing screens, and a hypertensive patient (BP 150/95) also gets an aldosterone-to-renin ratio.

D
ليش غلط
TSH is not in the incidentaloma work-up; its hormone screens are for Cushing syndrome, pheochromocytoma (metanephrines) and, in hypertensive patients, hyperaldosteronism (renin/aldosterone ratio).
