Which of the following statements regarding infection in patients with continuous ambulatory peritoneal dialysis (CAPD) is TRUE?

Correct Answer: D

Rationale: Infection is the most frequent CAPD complication peritonitis (e.g., Staph epidermidis) tops issues, true. Gram-negatives are less common Staph leads. Admission isn't required intraperitoneal antibiotics suffice. Cell count is >100 leukocytes 250 overstates. Frequency distinguishes it, key to CAPD morbidity, unlike organism, treatment, or count errors.

Correct Answer: C

Rationale: Wilms' tumor (nephroblastoma) affects infants, presents as a mass, is bilateral in ~7%, and often metastasizes to lungs not rarely. This corrects tumor behavior, vital for oncology, contrasting with metastasis rarity.

Correct Answer: B

Rationale: In acidosis, kidneys form ammonia, excrete keto-acids, and reabsorb bicarbonate not excrete it (conserved). This defines renal compensation, critical for pH balance, contrasting with bicarbonate loss.

Correct Answer: A

Rationale: Incomplete ureteric bud-metanephric fusion causes double ureter not polycystic, pelvic, lobulation, or horseshoe (fusion anomalies). This defines congenital defect, critical for urology, contrasting with other malformations.

Correct Answer: B

Rationale: Peritubular capillaries stem from efferent arterioles not afferent, intralobular, interlobular, or arcuate. This specifies post-glomerular flow, critical for reabsorption, contrasting with pre-glomerular sources.
