1. What is the primary goal in managing a child with chronic asthma?

• A. Achieve and maintain symptom control
• B. Avoid all physical activity
• C. Increase dietary sodium
• D. Restrict medication use

Correct answer: A

Rationale: The primary goal in managing a child with chronic asthma is to achieve and maintain symptom control. This helps improve the child's quality of life by reducing asthma symptoms and exacerbations. Choice B is incorrect because avoiding all physical activity is not recommended for children with asthma; in fact, regular physical activity can be beneficial. Choice C is incorrect as increasing dietary sodium is not a primary goal in managing asthma. Choice D is incorrect because restricting medication use can lead to uncontrolled asthma symptoms and complications.

2. What is a key sign of meningitis in an infant?

• A. Increased appetite
• B. Bulging fontanel
• C. Decreased respiratory rate
• D. Elevated blood pressure

Correct answer: B

Rationale: A bulging fontanel is a key sign of meningitis in infants, indicating increased intracranial pressure due to inflammation of the meninges. This can lead to the fontanel bulging. Choices A, C, and D are incorrect. Increased appetite is not typically associated with meningitis in infants; instead, they may have poor feeding. A decreased respiratory rate is not a common sign of meningitis in infants. Elevated blood pressure is also not a typical finding in infants with meningitis.

3. Which of the following is a function of carbohydrates in the body?

• A. They provide insulation and support for organs.
• B. They help regulate body temperature.
• C. They serve as the body's main structural components.
• D. They are the body's primary source of energy.

Correct answer: D

Rationale: The correct answer is D. Carbohydrates are the body's primary source of energy, fueling daily activities and bodily functions. Choice A is incorrect because insulation and organ support are primarily provided by adipose tissue and structural proteins, not carbohydrates. Choice B is incorrect because the regulation of body temperature is mainly controlled by processes like sweating and shivering, not carbohydrates. Choice C is incorrect because structural components like proteins are responsible for building tissues and organs, not carbohydrates.

4. What does a positive correlation between two variables indicate?

• A. One variable causes the other.
• B. Both variables move in the same direction.
• C. Both variables move in opposite directions.
• D. There is no relationship between the variables.

Correct answer: B

Rationale: A positive correlation between two variables indicates that they move in the same direction. This means that as one variable increases (or decreases), the other variable also increases (or decreases). Choice A is incorrect because correlation does not imply causation; it only shows a relationship between variables. Choice C is incorrect as it describes a negative correlation where variables move in opposite directions. Choice D is incorrect as a positive correlation implies a relationship between the variables.

5. What dietary recommendation is essential for a child with phenylketonuria (PKU)?

• A. High-protein diet
• B. Low-fat diet
• C. Low-phenylalanine diet
• D. High-fiber diet

Correct answer: C

Rationale: The correct answer is C: 'Low-phenylalanine diet.' Children with phenylketonuria (PKU) need to follow a low-phenylalanine diet to manage the condition. Phenylalanine is an amino acid found in protein-containing foods, and individuals with PKU have difficulty metabolizing it, leading to neurological damage and other complications. Therefore, restricting phenylalanine intake is crucial. Choice A, 'High-protein diet,' is incorrect because high protein intake would increase phenylalanine levels, worsening the condition. Choice B, 'Low-fat diet,' and Choice D, 'High-fiber diet,' are not the primary focus for PKU patients. The key dietary intervention for PKU is controlling phenylalanine intake, which is best achieved through a low-phenylalanine diet.
