Absolute contraindications for paediatric renal transplant include all except

Correct Answer: B

Rationale: Uncontrolled infection isn't absolute treatable, transplant possible post-resolution in kids. Uncontrolled malignancy halts transplant active disease risk. ABO incompatibility and positive crossmatch are absolute rejection barriers. Infection's treatability distinguishes it, critical for pediatric candidacy, unlike permanent or immunologic blocks.

Correct Answer: B

Rationale: Alfuzosin minimally affects ejaculatory function less selective for alpha-1a receptors in seminal vesicles/prostate, reducing retrograde ejaculation risk. Tamsulosin and silodosin, highly alpha-1a selective, disrupt emission common side effect. Naftopidil (less studied) also impacts ejaculation similar selectivity. Alfuzosin's broader profile distinguishes it, key to preserving sexual function in LUTS treatment, unlike selective blockers' ejaculatory interference.

Correct Answer: B

Rationale: Proteins are too large to filter into Bowman's capsule, unlike glucose, uric acid, and creatinine (small molecules). This distinguishes filtration selectivity, critical for normal renal function, contrasting with filtered solutes.

Correct Answer: B

Rationale: Angiotensin II targets blood vessels (vasoconstriction) and adrenal cortex (aldosterone release), not nerves, medulla (catecholamines), or nephron directly. This specifies RAAS effects, critical for sodium retention, contrasting with other systems.

Correct Answer: D

Rationale: The renal capsule (fibrous) encases the kidney, not cortex, medulla (inner), or pelvis (collecting). This distinguishes external anatomy, critical for protection, contrasting with internal regions.
