Questions About The Urinary System Questions
Question 1 of 5
In DCT, following are reabsorbed EXCEPT:
Correct Answer: A
Rationale: DCT reabsorbs Na+, Cl-, and water (ADH-dependent), but secretes K+ not reabsorbed. This distinguishes DCT ion handling, key for electrolyte balance, contrasting with reabsorption norms.
Question 2 of 5
The 'diluting segment' of the nephron is:
Correct Answer: C
Rationale: Ascending limb of Henle dilutes filtrate (NaCl reabsorption, water impermeable) not PCT, descending (concentrates), or collecting duct (ADH-dependent). This specifies diluting site, key for urine formation, contrasting with concentrating segments.
Question 3 of 5
Urethritis is caused by all EXCEPT:
Correct Answer: C
Rationale: Urethritis involves gonococci, Mycoplasma, and Ureaplasma not S. aureus (skin/UTI). This distinguishes urethritis pathogens, key for STD treatment, contrasting with non-urethral bacteria.
Question 4 of 5
A patient with gout has recently been started on allopurinol and is undergoing dose titration. What laboratory test should be monitored at monthly follow-up visits during this period?
Correct Answer: B
Rationale: Allopurinol reduces uric acid; monitoring serum uric acid assesses efficacy not urinalysis (stones), creatinine (kidney), AST (liver), or none. This specifies gout management, key for therapy adjustment, contrasting with renal/liver focus.
Question 5 of 5
Which of the following statements concerning the kidneys is false?
Correct Answer: D
Rationale: Kidneys are retroperitoneal, have 8-15 pyramids, distinct cortex/medulla, but span T12-L3 not L3-L5. This corrects positioning, vital for anatomy, contrasting with true traits.
