The nerve supply of the Adrenal gland is

Correct Answer: A

Rationale: Adrenal medulla receives sympathetic innervation (splanchnic nerves) triggers catecholamine release (e.g., epinephrine). Cortex lacks direct nerves hormonal control (ACTH). Parasympathetic doesn't supply adrenal vagal elsewhere. Medulla's sympathetic link distinguishes it, key to fight-or-flight, unlike cortex or parasympathetic errors.

Correct Answer: D

Rationale: Ultrasound abdomen/pelvis isn't recommended for initial LUTS assessment optional for complications (e.g., hydronephrosis), not routine. IPSS quantifies symptoms essential. DRE checks prostate size standard. Uroflow measures obstruction key. USS's secondary role distinguishes it, critical for guideline-based evaluation, unlike primary tools.

Correct Answer: C

Rationale: 15 mm Hg is standard pneumoperitoneum pressure for robotic/laparoscopic procedures balances visibility and safety (e.g., renal surgery). 5 mm Hg is too low poor exposure. 10 mm Hg suits pediatrics insufficient for adults. 20 mm Hg risks hypercapnia/ischemia excessive. 15 mm Hg distinguishes it, critical for optimal operative field without undue risk, unlike under- or over-pressurized options.

Correct Answer: B

Rationale: Potassium is reabsorbed in exchange for sodium in the distal tubule (Na+/K+ pump), not chloride (co-transported), calcium, or magnesium (different mechanisms). This distinguishes ion exchange, key for electrolyte balance, contrasting with passive processes.

Correct Answer: D

Rationale: Microvilli maximize surface area in the PCT for reabsorption, not loop or DCT (fewer). This specifies absorptive structure, key for efficiency, contrasting with minimal presence elsewhere.
