in renal tubule loop of henle is situated between

Correct Answer: A

Rationale: Loop of Henle lies between PCT and DCT, not collecting duct or none. This sequences nephron, critical for concentration, contrasting with misplacements.

Correct Answer: D

Rationale: Glomerular hydrostatic pressure is ~60 mmHg, not 65, 75, or 55. This quantifies filtration pressure, critical for GFR calculation, contrasting with misestimates.

Correct Answer: B

Rationale: Nephron (filtration to excretion) is the functional unit, not glomerulus (part), corpuscle (subset), or calyx (collecting). This defines renal unit, key for physiology, contrasting with components.

Correct Answer: C

Rationale: Renal papilla is the pyramid apex draining into calyces, not calyx or pelvis. This specifies medullary tip, key for urine collection, contrasting with collecting structures.

Correct Answer: D

Rationale: Male cystitis treatment with Augmentin/trimethoprim for 14 days is excessive 7 days suffices (e.g., complicated UTI risk higher, but not this long), inappropriate. Trimethoprim 3 days for female cystitis standard, short-course. Pyelonephritis with IV gentamicin/amoxicillin then 7-day Augmentin reasonable step-down. Nitrofurantoin in pregnancy (dose likely typo, 50-100 mg typical) for 7-14 days acceptable. Male duration overreach distinguishes it, key to guideline-based therapy, unlike appropriate regimens.
