1. Which nutrient is classified as a micronutrient?

• A. minerals
• B. proteins
• C. alcohols
• D. carbohydrates

Correct answer: A

Rationale: The correct answer is minerals. Micronutrients are required by the body in smaller amounts compared to macronutrients like proteins and carbohydrates. Proteins are macronutrients necessary for growth and repair, not classified as micronutrients. Alcohols and carbohydrates are not classified as micronutrients either.

2. In what position does the Pavlik harness hold a child's femurs for developmental hip dysplasia?

• A. Abduction
• B. Adduction
• C. Flexion
• D. Extension

Correct answer: A

Rationale: The Pavlik harness is designed to position a child's femurs in abduction for developmental hip dysplasia. Abduction helps align the hip joint correctly and promotes proper development in cases of hip dysplasia. Adduction (choice B) brings the legs closer to the midline, which is not the desired position in this condition. Flexion (choice C) refers to bending at a joint, while extension (choice D) is the opposite of flexion. However, in the case of developmental hip dysplasia, abduction is crucial for the Pavlik harness to work effectively.

3. What is one benefit of using a large sample size in an experiment?

• A. Chance variation is less likely to affect the results.
• B. The possibility of a placebo effect is eliminated.
• C. The experiment will be double-blind.
• D. The control group will be similar to the experimental group.

Correct answer: A

Rationale: Corrected Rationale: Using a large sample size reduces the likelihood of chance variation affecting the results, providing more reliable data. Choice B is incorrect because the placebo effect is related to participants' beliefs, not sample size. Choice C is incorrect as double-blind refers to a method of reducing bias, not directly related to sample size. Choice D is incorrect because the similarity between the control and experimental groups is not solely dependent on sample size.

4. Approximately how many milliliters are contained in a half-cup of milk?

• A. 50
• B. 85
• C. 120
• D. 170

Correct answer: C

Rationale: A half-cup of milk is equivalent to approximately 120 milliliters. This conversion is standard and commonly used in cooking and baking. Choice A (50 milliliters) is too low for a half-cup measurement. Choice B (85 milliliters) is also lower than the standard half-cup measurement of 120 milliliters. Choice D (170 milliliters) is too high for a half-cup, making it an incorrect option.

5. What is a common complication of untreated asthma in children?

• A. Delayed puberty
• B. Growth retardation
• C. Chronic sinusitis
• D. Frequent headaches

Correct answer: C

Rationale: The correct answer is C: Chronic sinusitis. Untreated asthma can lead to chronic sinusitis in children due to prolonged inflammation and infection of the respiratory tract. Choices A, B, and D are incorrect. Delayed puberty and growth retardation are not common complications of untreated asthma in children. Frequent headaches may be associated with asthma exacerbations but are not typical long-term complications.
