The most reliable clinical sign of Torsion Testes is

Correct Answer: C

Rationale: Absent cremasteric reflex is most reliable for testicular torsion lost ipsilateral reflex (stroke scrotum, no testis rise) signals torsion's nerve disruption. Prehn's (pain relief lifting) is inconsistent variable. Transverse lie suggests torsion less specific. Swelling/oedema/tenderness are late non-diagnostic alone. Reflex absence distinguishes it, critical for acute diagnosis, unlike pain, position, or swelling signs.

Correct Answer: C

Rationale: Juxtaglomerular (JG) cells secrete renin to regulate blood pressure, not the macula densa (senses NaCl), JG apparatus (collective structure), or cortical nephron (unit). This pinpoints renin's source, key for RAAS, contrasting with broader terms.

Correct Answer: D

Rationale: Glucose is fully reabsorbed in healthy kidneys, unlike magnesium, urea, and uric acid (excreted). This distinguishes normal urine composition, key for glycosuria detection, contrasting with waste products.

Correct Answer: A

Rationale: Creatinine is filtered and excreted without a threshold, unlike ascorbic acid, sodium, and citric acid (reabsorbed to limits). This identifies non-threshold excretion, key for GFR assessment, contrasting with regulated solutes.

Correct Answer: C

Rationale: Renal pyramids reside in the medulla, not columns, cortex, or pelvis (collecting). This locates pyramids, key for concentrating urine, contrasting with cortical structures.
