Final answer:
A clear urine sample is expected to have very little sediment on centrifugation and be transparent. It should not contain red blood cells, significant amounts of sediment, or mucus. Normally, urine has an aromatic odor, with different odors suggesting different conditions, such as diabetes. The correct option is c.
Step-by-step explanation:
In a clear urine sample, one would expect to see very little sediment on centrifugation (option c). Normal urine should be clear and transparent. The presence of any of the following could indicate an underlying health issue:
- Mucus, which may suggest an inflammation or infection.
- Red blood cells (RBCs), which could indicate conditions such as nephritis, trauma, or kidney stones.
- White blood cells, which may indicate an infection such as a urinary tract infection.
- Cloudiness, which might be due to bacteria or too many white blood cells.
Additionally, normal urine has an aromatic smell. A fruity odor in urine can be a sign of diabetes, as it may indicate the presence of ketone bodies due to cells not being able to utilize glucose efficiently.
Finally, the color of urine is also a good indicator of health. A greenish yellow color is normal, but red may indicate hematuria, and a milky color could suggest the presence of pus or protein in the urine. The correct option is c.
