C Correct answer
Explanation

Hemodialysis is the most common type of dialysis. This process uses an artificial kidney (hemodialyzer) to remove waste and extra fluid from the blood. The blood is removed from the body and filtered through the artificial kidney. The filtered blood is then returned to the body with the help of a dialysis machine.

So, the correct option is 'Uremia'.

  2. Barium chloride

  3. Zinc sulphate

  4. Calcium oxalate

D Correct answer
Explanation
Approximately 70-80% of kidney stones are composed of calcium oxalate and calcium phosphate. Of the rest, 10% are struvite, 10% of uric acid; and less than 1% are composed of cystine or are diagnosed as drug-related stones. Calcium and uric acid stones are more common in men; women have more struvite stones.
So, the correct option is 'Calcium oxalate'.

A Correct answer
Explanation

Kidney stones are also called urine calculi. Urine calculi are small stones which are hard deposit in the kidneys and cause pain when are passed through the urinary stream. They are formed often to do accumulation of calcium oxalate crystals.

So, the correct answer is 'Option A'.

Identify correctly matched pairs.
1. Uremia- Excessive amount of urea in blood
2. Hyperglycemia- Excess glucose in blood
3. Absence of factor VIII- Haemophilia
4. X-linked disorder- Glycosuria

  1. 1, 2, 3 correct

  2. 1, 2 correct

  3. 2, 4 correct

  4. 1, 3 correct
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
1. Uremia is the condition in which there is excess urea present in the body. It occurs when there is decreased excretion of urea in the kidney.
2. Hyperglycemia is the condition of excess glucose in blood. It can occur due to factor like decreased level of insulin in blood.
3. Factor VIII is known as anti-haemophilic factor. Deficiency of this factor causes classical haemophilia in which blood clot formation does not occur and the bleeding continues.
4. Glycosuria is the presence of glucose in urine. This indicates abnormal absorption of glucose in the renal tubules.
Hence, 1,2 and 3 options are correctly matched pairs.
So, the correct answer is '1, 2, 3 correct'.

Black urine disease is due to

  1. Absence of alkapton oxidase

  2. Absence of homogentisic acid

  3. Metabolism of phenylalanine

  4. Metabolism of tyrosine
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Black urine disease, or alkaptonuria, is caused by a deficiency of the enzyme homogentisate 1,2-dioxygenase (alkapton oxidase). This deficiency leads to the accumulation of homogentisic acid, which turns black upon oxidation in urine.

Which of the following disease shows the blockage of kidney tubules and causes severe back pain?

  1. Renal calculi

  2. Kidney failure

  3. Uremia

  4. Nephritis
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Renal calculi is also called as kidney stones. Renal calculi mainly contains calcium oxalate. It also includes cystine stones or uric acid stones. It results in the blockage of kidney tubules by a solid mass of crystals. It causes severe pain in the back, abdomen, flank and groin. 

Thus, the correct answer is option A.
