Questions and Answers

1.

Identify the arrowed object. Observe the broken ends of the cast.
- A.
  
  Waxy Cast
- B.
  
  Hyaline Cast
- C.
  
  RBC Cast
- D.
  
  Granualar Cast
Correct Answer
A. Waxy Cast

Explanation
The correct answer is Waxy Cast. Waxy casts are formed when there is stasis or slow flow of urine in the renal tubules. They have a smooth, glassy appearance and are often seen in chronic renal disease. The broken ends of the cast may indicate damage or deterioration of the cast structure.

Identify the arrowed object.
- A.
  
  Waxy Cast
- B.
  
  Granular Cast
- C.
  
  RBC Cast
- D.
  
  WBC Cast
Correct Answer
B. Granular Cast
4.

Choose the correct name.
- A.
  
  Leucine Crystal
- B.
  
  Tyrosine Crystal
- C.
  
  Calcium Oxalate Crystal
- D.
  
  Triple Phosphate Crystal
Correct Answer
C. Calcium Oxalate Crystal

Explanation
Calcium oxalate crystals are a common type of crystal that can form in the urine or in various tissues of the body. They are often found in the urine of individuals with kidney stones or other urinary tract disorders. The crystals are composed of calcium and oxalate, and their presence can indicate an underlying medical condition. Therefore, the correct name for the given answer is Calcium Oxalate Crystal.

5.

Identify the arrowed object.
- A.
  
  Hyaline Cast
- B.
  
  Waxy Cast
- C.
  
  Fiber (exogenous)/fecal contamination
- D.
  
  Parasitic Worm
Correct Answer
C. Fiber (exogenous)/fecal contamination

Explanation
The arrowed object in the image is most likely fiber (exogenous)/fecal contamination. This can be inferred from the fact that hyaline cast and waxy cast are types of casts found in urine samples, while a parasitic worm would have a distinct appearance and would not be classified as a cast. Therefore, the presence of fiber or fecal contamination is the most plausible explanation for the arrowed object in the image.

6.

Identify the objects, regular light (left) and under polarized light (right).
- A.
  
  Starch Granules
- B.
  
  Pollen Granules
- C.
  
  Stain Precipitate
- D.
  
  Fat Droplets
Correct Answer
A. Starch Granules

Explanation
Starch granules can be identified under both regular light and polarized light. When viewed under regular light, starch granules appear as translucent, refractive bodies with a characteristic shape. Under polarized light, starch granules show birefringence, meaning they exhibit different refractive indices in different directions, resulting in a distinct pattern of colors. This property helps in distinguishing starch granules from other objects like pollen granules, stain precipitate, and fat droplets, which do not exhibit birefringence.
