1. 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.

2. After surgical repair of a cleft palate, what should be used to prevent injury to the suture line?

• A. Straw
• B. Spoon
• C. Syringe
• D. Cup

Correct answer: C

Rationale: The correct answer is C: Syringe. Using a syringe helps in feeding without causing injury to the suture line after cleft palate repair because it avoids direct contact with the suture area. Straws and spoons can potentially put pressure on the suture line, leading to injury. Cups may not provide the necessary control to prevent contact with the suture line, unlike a syringe.

3. What is the most effective therapy for maintaining remission of acute lymphoblastic leukemia?

• A. Surgery to remove enlarged lymph nodes
• B. Long-term chemotherapy
• C. Nutritional supplements to enhance blood cell production
• D. Blood transfusions to replace ineffective red cells

Correct answer: B

Rationale: The correct answer is B: Long-term chemotherapy. Long-term chemotherapy, specifically with methotrexate, is the most effective therapy for maintaining remission in acute lymphoblastic leukemia. Surgery to remove enlarged lymph nodes (Choice A) is not the primary treatment for leukemia. Nutritional supplements (Choice C) may support overall health but are not the mainstay therapy for maintaining leukemia remission. Blood transfusions (Choice D) are used to address anemia in some cases but are not the primary treatment for maintaining remission in acute lymphoblastic leukemia.

4. What dietary modification is important for a child with celiac disease?

• A. Increase dairy intake
• B. Avoid gluten-containing foods
• C. Decrease protein intake
• D. Increase fiber intake

Correct answer: B

Rationale: The correct answer is B: Avoid gluten-containing foods. For a child with celiac disease, it is crucial to eliminate gluten from their diet to manage the condition effectively. Gluten triggers an immune response in individuals with celiac disease, leading to symptoms and damage to the small intestine. Choices A, C, and D are incorrect because increasing dairy intake, decreasing protein intake, or increasing fiber intake are not specific dietary modifications for managing celiac disease.

5. Which statement best describes the composition of most foods?

• A. Most foods contain a mixture of the three energy nutrients, with one or two predominating.
• B. Foods do not typically contain equal amounts of the three energy nutrients.
• C. Most foods contain mixtures of the three energy nutrients, although only one or two may predominate.
• D. Most foods contain all three energy nutrients in varying amounts.

Correct answer: C

Rationale: The correct answer is C. Most foods contain a mixture of the three energy nutrients (carbohydrates, proteins, fats), with one or two predominating. Choice A is correct because most foods do contain a combination of energy nutrients, with one or two types usually being predominant. Choice B is incorrect as foods typically do not contain equal amounts of carbohydrates, proteins, and fats. Choice D is incorrect because most foods contain all three energy nutrients, not just one or two types.
