Question 1
Which term describes a stone in the ureter?
Correct Answer:
Ureterolith
Explanation:
In urinary stone terminology, the location determines the name, with lith referring to a stone. A stone located in the ureter is called a ureterolith. This directly identifies the object and its exact location. The other terms describe different things: nephrolithiasis refers to kidney stones or the condition of having them, cystolith is a stone in the bladder, and ureterolithiasis would describe stones in the ureter as a disease state rather than the stone itself. So the term that names the stone itself in the ureter is ureterolith.
Question 2
Acidic urine favors which types of stones?
Correct Answer:
Uric acid and cystine stones
Explanation:
When urine is acidic, the solubility of certain stone-forming substances decreases, making crystal formation more likely. Uric acid is less soluble in low pH urine, so uric acid stones form more readily in acidic conditions. Cystine also has very low solubility in acidic urine, and stones from this amino acid tend to appear when the urine is acidic. In contrast, calcium phosphate and struvite stones prefer alkaline urine, and calcium oxalate stones can form over a wide pH range and are not specifically tied to acidity. Therefore, acidic urine favors uric acid stones and cystine stones.
Question 3
What is the typical presenting symptom of bladder cancer?
Correct Answer:
Painless hematuria
Explanation:
Painless hematuria occurs because bladder tumors irritate and bleed from the bladder lining as they grow, releasing blood into the urine without causing pain. This makes painless visible bleeding (or microscopic blood on urinalysis) the classic presenting sign of bladder cancer. Severe flank pain would suggest obstruction or another issue like a kidney stone or pyelonephritis, not the typical early presentation of bladder cancer. Jaundice points to liver or biliary problems, which are not related to bladder tumors. While some patients may have urinary symptoms such as frequency or dysuria, the hallmark clue that most strongly points to bladder cancer is painless hematuria.
Question 4
Which dipstick parameter is used to detect leukocyte esterase in urine?
Correct Answer:
Leukocyte esterase
Explanation:
Leukocyte esterase on a urine dipstick is the test that detects this enzyme released by neutrophils in the presence of inflammation or infection in the urinary tract. When white blood cells are present in the urine (pyuria), they release leukocyte esterase, and the dipstick reaction is positive. This makes it a direct marker for leukocytes in urine, i.e., a sign of possible a urinary tract infection. The other dipstick parameters measure different things—nitrite indicates bacterial conversion of nitrates, glucose shows glycosuria, and protein reflects proteinuria—so they do not specifically detect leukocyte esterase.
Question 5
What laboratory finding is commonly seen after an infection in acute post-streptococcal glomerulonephritis?
Correct Answer:
Decreased Complement C3 Levels With Nephritic-Range Proteinuria and Hematuria
Explanation:
After a streptococcal infection, acute post-streptococcal glomerulonephritis is driven by immune complex–mediated injury in the glomeruli. Those immune complexes activate the complement system and consume C3, so the typical lab finding is a low C3 level. C4 is usually normal in this setting. Clinically this matches a nephritic picture: hematuria (often with red cell casts), and nephritic-range proteinuria, along with possible hypertension and mild oliguria. The C3 level tends to rebound to normal as the illness resolves over weeks. Therefore, the best answer is a decreased C3 level with nephritic-range proteinuria and hematuria.
