You have been asked to help a top nutrition researcher conduct human experiments on vitamin C. As the subjects walk into the laboratory, you distribute all the vitamin C pill bottles to the girls and all the placebo pill bottles to the boys. What should you have done?

  • A. Giving all the boys the vitamin C and the girls the placebo, and telling them what they were getting.
  • B. Distributing the bottles randomly, randomizing the subjects, and telling them what they were getting.
  • C. Telling the subjects which group they were in, but preventing yourself from knowing the contents of the pill bottles.
  • D. Preventing yourself from knowing what is in the pill bottles, and distributing the bottles randomly to the subjects.
Correct Answer: D

Rationale: The correct approach in a scientific experiment is to prevent yourself from knowing the contents of the pill bottles and distribute them randomly to the subjects. This randomization helps to avoid bias and ensures that the results are not influenced by preconceived notions. Option A is incorrect because it introduces gender bias by assigning pills based on gender. Option B is incorrect as it mentions telling the subjects what they are getting, which could lead to placebo effects. Option C is incorrect as it suggests disclosing group information to the subjects, which can also introduce bias.

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.

If a group of people consumes an amount of protein equal to the estimated average requirement for their population group, what percentage of people will receive insufficient amounts?

  • A. 10
  • B. 25
  • C. 33
  • D. 50
Correct Answer: D

Rationale: If a group consumes an amount of protein equal to the estimated average requirement, 50% of the people will receive insufficient amounts. The estimated average requirement is the amount of a nutrient that is estimated to meet the requirement of half the healthy individuals in a particular life stage and gender group. Therefore, 50% of the group will not be meeting their individual needs if they are consuming only the average requirement. Choices A, B, and C are incorrect because at the estimated average requirement level, a higher percentage than those values will receive insufficient amounts.

Following diarrhea, which foods should be offered to the school-age child?

  • A. Apricots and peaches
  • B. Chocolate milk
  • C. Applesauce and milk
  • D. Bananas and rice
Correct Answer: D

Rationale: After a bout of diarrhea, it is important to offer foods that are gentle on the stomach and help in recovery. Bananas and rice are commonly recommended as they are easily digestible and can help firm up stools. Apricots, peaches, and applesauce may be too acidic and fibrous, potentially aggravating the stomach. Chocolate milk is high in sugar and can worsen diarrhea due to its lactose content.

What dietary recommendation should be made to a child with iron-deficiency anemia?

  • A. Increase intake of dairy products
  • B. Include high-iron foods like spinach and meat
  • C. Decrease protein intake
  • D. Avoid all grains
Correct Answer: B

Rationale: The correct recommendation for a child with iron-deficiency anemia is to include high-iron foods like spinach, red meat, and beans in their diet. These foods are rich sources of iron and can help address the deficiency. Choice A is incorrect as dairy products do not provide significant iron content. Choice C is incorrect because protein intake does not need to be decreased; in fact, lean meats are good sources of iron. Choice D is also incorrect as whole grains can be a part of a healthy diet and do not need to be avoided in this case.
