Urine colour turns milky due to presence of:
- A.
Purulent genitourinary track diseases
- B.
Chyluria
- C.
All
- D.
None
Correct Answer
C. AllExplanation
The correct answer is "All". Urine color can turn milky due to the presence of both purulent genitourinary tract diseases and chyluria. Purulent genitourinary tract diseases refer to infections in the urinary system that cause the urine to become cloudy or milky due to the presence of pus. Chyluria, on the other hand, is a condition where lymphatic fluid leaks into the urinary system, giving the urine a milky appearance. Therefore, both conditions can cause the urine to turn milky.Rate this question:

Fruity odour in urine is due to:
- A.
Ketosis
- B.
Glucoseuria
- C.
Bacterial Infection
- D.
All
Correct Answer
A. KetosisExplanation
Fruity odor in urine is due to ketosis. Ketosis occurs when the body starts breaking down fat for energy instead of glucose. This process produces ketones, which are released in the urine and can cause a fruity smell. Glucoseuria refers to the presence of glucose in the urine, which can be a sign of diabetes. Bacterial infection may cause changes in urine color or odor, but it is not specifically associated with a fruity smell. Therefore, the correct answer is ketosis.Rate this question:

Factor III (Tissue Factor) Lead which pathway in cascade theory??
- A.
Extrinsic Pathway
- B.
Intransic Pathway
- C.
Both
- D.
Common Pathway
Correct Answer
A. Extrinsic PathwayExplanation
The correct answer is the Extrinsic Pathway. Factor III, also known as Tissue Factor, is a key component of the Extrinsic Pathway in the coagulation cascade theory. This pathway is activated when there is tissue damage, and Factor III is released from damaged tissue. It then forms a complex with Factor VII, leading to the activation of Factor X and ultimately resulting in the formation of a blood clot. The Intrinsic Pathway, on the other hand, is activated by contact with foreign surfaces, such as exposed collagen, and does not involve Factor III.Rate this question:
