1. Which vitamin deficiency is most likely to be associated with increased risk of macular degeneration?

• A. Vitamin A
• B. Vitamin B12
• C. Vitamin C
• D. Vitamin E

Correct answer: D

Rationale: Vitamin E is an antioxidant that helps protect eye health and prevent macular degeneration.

2. What are symptoms of uncontrolled type 1 diabetes?

• A. Depression, anxiety, and fatigue
• B. Increased thirst, urination, and hunger
• C. Weight gain, macrosomia, and food cravings
• D. Poor wound healing, blurred vision, and recurrent infections

Correct answer: B

Rationale: The correct answer is B: Increased thirst, urination, and hunger. Uncontrolled type 1 diabetes typically presents with classic symptoms including polydipsia (increased thirst), polyuria (frequent urination), and polyphagia (increased hunger). These symptoms are often accompanied by weight loss due to the body's inability to properly utilize glucose for energy. Choices A, C, and D are incorrect as they do not align with the typical symptoms of uncontrolled type 1 diabetes. Depression, anxiety, fatigue, weight gain, macrosomia, food cravings, poor wound healing, blurred vision, and recurrent infections are not primary symptoms associated with uncontrolled type 1 diabetes.

3. Which biomolecule is responsible for the storage and transfer of genetic information?

• A. Carbohydrates
• B. Proteins
• C. Lipids
• D. Nucleic acids

Correct answer: D

Rationale: Nucleic acids, such as DNA and RNA, are the biomolecules responsible for storing and transferring genetic information within cells. Carbohydrates, proteins, and lipids do not have this specific function. Carbohydrates are mainly used for energy storage, structural support, and cellular communication. Proteins are involved in various cellular functions such as enzymatic reactions, structural support, and signaling. Lipids play roles in energy storage, cell membrane structure, and signaling.

4. What is the initial major sign of acute renal failure?

• A. Oliguria
• B. Hematuria
• C. Proteinuria
• D. Glycosuria

Correct answer: A

Rationale: Oliguria, or reduced urine output, is often the initial major sign of acute renal failure. This reduction in urine output indicates that the kidneys are not functioning properly. Hematuria (blood in urine), proteinuria (presence of protein in urine), and glycosuria (presence of glucose in urine) are not typically the initial major signs of acute renal failure. While they may be present in certain conditions, oliguria is the most common and critical indicator of acute renal failure.

5. Which vitamin is essential for proper blood clotting?

• A. Vitamin A
• B. Vitamin E
• C. Vitamin K
• D. Vitamin C

Correct answer: C

Rationale: Vitamin K is vital for the synthesis of clotting factors, which are necessary for proper blood clotting. Vitamin A (Choice A) is important for vision and skin health, not blood clotting. Vitamin E (Choice B) is an antioxidant that helps protect cells from damage but is not directly involved in blood clotting. Vitamin C (Choice D) is essential for collagen synthesis and a healthy immune system, but it does not play a direct role in blood clotting.
