1. What is a common side effect of the antibiotic tetracycline in children?

• A. Discoloration of teeth
• B. Increased appetite
• C. Elevated blood glucose levels
• D. Decreased bone density

Correct answer: A

Rationale: Discoloration of teeth is a well-known side effect of tetracycline, especially when administered to children below 8 years of age. Tetracycline can bind to calcium ions in developing teeth, causing them to become discolored and appear yellow or brown. Increased appetite, elevated blood glucose levels, and decreased bone density are not commonly associated with the use of tetracycline in children, making them incorrect choices.

2. What role do fats play in the human body?

• A. They provide a concentrated source of energy.
• B. They are the building blocks of enzymes and hormones.
• C. They are essential for brain function and development.
• D. They aid in the digestion of food.

Correct answer: D

Rationale: Fats play various essential roles in the human body, one of which is aiding in the digestion of food. While fats do provide a concentrated source of energy, the primary source is carbohydrates. Proteins are the building blocks of enzymes and hormones, not fats. Essential fatty acids found in fats are vital for brain function and development, but this is not the primary role of fats in the body.

3. What is the recommended treatment for a child with a first-degree burn?

• A. Immediate application of ice
• B. Administration of oral antibiotics
• C. Application of cool, moist compresses
• D. Application of hot packs

Correct answer: C

Rationale: The recommended treatment for a child with a first-degree burn is the application of cool, moist compresses. This helps in reducing pain and swelling without causing further damage to the skin. Applying ice directly to a burn can lead to frostbite and worsen the injury (Choice A). Oral antibiotics are not necessary for first-degree burns as they do not typically involve infection (Choice B). Hot packs should be avoided as they can further damage the skin and increase inflammation (Choice D).

4. How many minerals are known to be essential for human nutrition?

• A. 8
• B. 12
• C. 16
• D. 20

Correct answer: C

Rationale: There are 16 essential minerals required for human nutrition. These minerals include calcium, potassium, iron, and others. Choice A (8) is incorrect as it underestimates the number of essential minerals. Choice B (12) is also incorrect as it does not encompass the full count of essential minerals. Choice D (20) is incorrect as it overestimates the number of essential minerals.

5. What is the term for the study of how diet affects gene expression?

• A. Epigenetics
• B. Nutrigenomics
• C. Genomics
• D. Genetics

Correct answer: B

Rationale: Nutrigenomics is the study of how diet affects gene expression, influencing health outcomes and disease risk. Epigenetics (choice A) involves changes in gene expression or cellular phenotype caused by mechanisms other than changes in the underlying DNA sequence. Genomics (choice C) is the study of an organism's entire genome. Genetics (choice D) is the study of heredity and the variation of inherited characteristics.
