Understanding Gout and Uric Acid Metabolism

What are the two materials that DNA and RNA break down into before becoming xanthine?

• Cytosine and uracil

• Hypoxanthine and guanine

• Adenine and thymine

• Xanthine and uric acid

What is the primary role of the kidneys in relation to uric acid?

• To store uric acid for later use

• To produce uric acid

• To filter uric acid out of the blood

• To convert uric acid into xanthine

What dietary advice is commonly given to patients with gout?

• Increase sugar intake

• Limit meat and alcohol consumption

• Avoid dairy products

• Eat more fruits and vegetables

How does alcohol consumption affect uric acid levels?

• It competes with uric acid for excretion

• It increases uric acid production

• It decreases uric acid production

• It has no effect on uric acid levels

What is the primary cause of primary gout?

• Kidney disease

• Excessive alcohol consumption

• Unknown intrinsic factors

• High meat intake

What is the term used to describe the kidney's inability to filter uric acid effectively?

• Renal deficiency

• Renal efficiency

• Renal insufficiency

• Renal sufficiency

Which disease is characterized by an overproduction of blood cells leading to increased uric acid?

• Diabetes

• Leukemia

• Hypertension

• Arthritis

What is the role of the enzyme HPRT in uric acid metabolism?

• It breaks down uric acid into xanthine

• It converts hypoxanthine and guanine into earlier pathway components

• It increases uric acid production

• It stores uric acid in the kidneys

What is a unique symptom of Lesch-Nyhan syndrome?

• Excessive thirst

• Self-injurious behavior

• Increased appetite

• Frequent urination

Which of the following is NOT a secondary cause of gout?

• Renal insufficiency

• Primary gout

• Leukemia

• Lesch-Nyhan syndrome
