Urine colour turns milky due to presence of:
Correct Answer
C. All
Explanation
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.
5.
Fruity odour in urine is due to:
Correct Answer
A. Ketosis
Explanation
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.

Correct Answer
B. Prehepatic Bilirubin
Explanation
Unconjugated bilirubin is also known as prehepatic bilirubin because it refers to the form of bilirubin that has not yet been processed by the liver. Prehepatic bilirubin is produced when red blood cells break down, and it is transported to the liver where it undergoes conjugation to become conjugated bilirubin. Therefore, the correct answer is prehepatic bilirubin.
15.
Brilliant cresyl blue or new methylene blue are stains used for counting
Correct Answer
B. Reticulocytes
Explanation
Reticulocytes are immature red blood cells that contain remnants of ribonucleic acid (RNA) and are stained by Brilliant cresyl blue or new methylene blue. These stains help in identifying and counting reticulocytes in a blood sample. Howell-Jolly bodies are small fragments of nuclear material that can be seen in red blood cells, but they are not stained by these dyes. Malaria is a parasitic infection that affects red blood cells, but it is not directly related to the staining of reticulocytes. Platelets are blood cells involved in clotting and are not stained by these dyes.
16.
In the formation of urine, the function of the glomerulus is
Correct Answer
B. Simple filtration
Explanation
The glomerulus is responsible for simple filtration in the formation of urine. It acts as a filter, allowing small molecules such as water, electrolytes, and waste products to pass through while preventing larger molecules like proteins and blood cells from entering the filtrate. This process helps in the removal of waste products and excess water from the blood, which eventually leads to the formation of urine.
17.
Which of the following tests is specific for urinary glucose?
Correct Answer
A. Benedict's
Explanation
Benedict's test is specific for urinary glucose because it is a chemical test that detects the presence of reducing sugars, including glucose, in a urine sample. Benedict's reagent reacts with the glucose molecules, causing a color change from blue to green, yellow, orange, or red, depending on the concentration of glucose present. This test is commonly used to screen for diabetes mellitus or monitor blood sugar control in diabetic patients. Clinitest and deep strip tests are also used to detect glucose in urine, but Benedict's test is specifically designed for this purpose. Pandy test, on the other hand, is used to detect proteins in urine.

Polyuria is often associated with increased thirst and frequent urination, and it is important to identify and address the underlying cause of this condition.
25.
Factor III (Tissue Factor) Lead which pathway in cascade theory??
Correct Answer
A. Extrinsic Pathway
Explanation
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.
