Questions About The Urinary System Questions
Question 1 of 5
Which is not a criterion in International Prostate Symptom Score?
Correct Answer: D
Rationale: IPSS assesses LUTS frequency, urgency, incomplete voiding (storage/voiding symptoms) but not dysuria (pain), which is infection/inflammation-related, not BPH-focused. Frequency (how often), urgency (sudden need), and incomplete voiding (residual) quantify obstruction/irritation. Dysuria's exclusion distinguishes IPSS, critical for symptom scoring, unlike pain inclusion.
Question 2 of 5
Which of these has the highest concentration in the urine?
Correct Answer: C
Rationale: Uric acid concentrates in urine as a waste product, unlike glucose (reabsorbed), sodium (regulated), or phosphate (variable). This highlights excretory priority, vital for purine metabolism, contrasting with reabsorbed substances.
Question 3 of 5
Most tubular re-absorption occurs at the
Correct Answer: C
Rationale: Proximal convoluted tubule (PCT) reabsorbs ~65-70% of filtrate (glucose, Na+), not loop, DCT (fine-tuning), or glomerulus (filtration). This highlights PCT dominance, vital for bulk reabsorption, contrasting with later segments.
Question 4 of 5
The entrance into the kidney is called the
Correct Answer: C
Rationale: The hilum is the kidney's entry/exit point for vessels/ureter, not sinus (cavity), column (cortex), or pyramid (medulla). This defines renal gateway, vital for vascular connections, contrasting with structural terms.
Question 5 of 5
Renal secretion of a compound usually occurs from the into the distal convoluted tubule.
Correct Answer: D
Rationale: Secretion moves substances from peritubular capillaries to DCT, not loop, glomerulus (filtration), or vasa recta (exchange). This defines secretion pathway, vital for drug elimination, contrasting with reabsorption.
