1. What is critical for preventing complications in an infant with hypothyroidism?

• A. Excessive growth
• B. Cognitive impairment
• C. Damage to the nervous system
• D. Damage to the urinary system

Correct answer: B

Rationale: The correct answer is B: Cognitive impairment. In infants with hypothyroidism, prompt administration of oral thyroid hormone replacement is crucial to prevent cognitive impairment and other serious complications. Excessive growth (choice A) is not a typical complication of hypothyroidism in infants. While hypothyroidism can affect the nervous system (choice C), cognitive impairment is more specific to untreated cases. Damage to the urinary system (choice D) is not a common complication of hypothyroidism in infants.

2. When an increase in exercise is accompanied by a decrease in body weight, it is an example of what?

• A. variable effect
• B. positive correlation
• C. negative correlation
• D. randomization effect

Correct answer: C

Rationale: When an increase in exercise is accompanied by a decrease in body weight, it demonstrates a negative correlation. This means that as one variable (exercise) increases, the other variable (body weight) decreases. Choice A, 'variable effect,' is vague and does not accurately describe the relationship between exercise and body weight. Choice B, 'positive correlation,' is incorrect because in a positive correlation, both variables would increase or decrease together. Choice D, 'randomization effect,' is unrelated to the scenario described.

3. What is a common treatment for a child with moderate to severe eczema?

• A. Topical corticosteroids
• B. Oral antibiotics
• C. Frequent saline irrigation
• D. High-calcium diet

Correct answer: A

Rationale: Topical corticosteroids are the correct answer for a child with moderate to severe eczema. These medications are commonly used to reduce inflammation and itching associated with eczema. Oral antibiotics (Choice B) are not typically used in eczema treatment unless there is a secondary bacterial infection. Frequent saline irrigation (Choice C) may aid in wound care but is not a primary treatment for eczema. A high-calcium diet (Choice D) is not a standard treatment for eczema and does not target the underlying inflammatory process that causes eczema symptoms.

4. What is the primary goal in managing a child with cystic fibrosis?

• A. Increase dietary fat intake
• B. Prevent lung infections
• C. Increase physical activity
• D. Ensure high protein intake

Correct answer: B

Rationale: The primary goal in managing a child with cystic fibrosis is to prevent lung infections. Cystic fibrosis primarily affects the respiratory system, leading to thick mucus buildup in the lungs, which increases the risk of infections. Preventing lung infections through proper respiratory care, medications, airway clearance techniques, and vaccinations is crucial in managing cystic fibrosis. While dietary interventions like increasing dietary fat intake, ensuring high protein intake, and promoting physical activity are also important aspects of cystic fibrosis management, preventing lung infections takes precedence as it directly addresses a major complication of the condition.

5. 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.
