Urinary System Mcq Questions Questions
Question 1 of 5
Factor affecting GFR are:
Correct Answer: D
Rationale: Glomerular filtration rate (GFR) is influenced by renal blood flow (perfusion), glomerular capillary hydrostatic pressure (driving filtration), and ureteric obstruction (back pressure reducing filtration) all listed factors. This comprehensive impact distinguishes GFR regulation, critical for kidney function assessment, contrasting with single-factor misconceptions.
Question 2 of 5
Minimal change disease and membranous glomerulonephritis share which of the following characteristics?
Correct Answer: A
Rationale: Both minimal change disease (MCD) and membranous glomerulonephritis (MGN) cause nephrotic syndrome (proteinuria, edema) MGN has IgG deposits, MCD responds to steroids, neither thickens loops typically. This distinguishes shared nephrotic features, key for diagnosis, contrasting with specific traits.
Question 3 of 5
The mesonephros cranial to its junction with the ureteric bud gives the following:
Correct Answer: A
Rationale: Mesonephros cranial to ureteric bud forms male genital ducts (epididymis, vas) not female, paramesonephric (Mullerian), or utricle (sinus derivative). This distinguishes embryonic urogenital development, key for sex differentiation, contrasting with female structures.
Question 4 of 5
Which of the following crystalloids are major constituents in 75-85% of renal calculi plus calcium:
Correct Answer: C
Rationale: Most renal calculi (75-85%) are calcium oxalate or phosphate not cystine (rare), urate (less common), or mixed. This distinguishes stone composition, vital for treatment, contrasting with minority types.
Question 5 of 5
Medications associated with renal calculus formation are all EXCEPT
Correct Answer: D
Rationale: Acetohydroxamic acid prevents stones (inhibits urease in struvite cases), not causes them therapeutic role. Topiramate (anticonvulsant) alkalinizes urine, forming calcium phosphate stones. Triamterene (diuretic) crystallizes directly drug stones. Ephedrine (stimulant) links to stones via dehydration risk factor. Acetohydroxamic's preventive action distinguishes it, critical for infection stones, unlike stone-inducing drugs.
