1. What is an essential aspect of managing a child with juvenile idiopathic arthritis (JIA)?

A. Encouraging joint mobility and physical therapy
B. Restricting all forms of exercise
C. Increasing sugar intake
D. Using only oral medications

Correct answer: A

Rationale: Encouraging joint mobility and physical therapy is crucial in managing juvenile idiopathic arthritis (JIA). This approach helps maintain joint function, reduce stiffness, and improve the overall quality of life for children with JIA. Restricting all forms of exercise (Choice B) is not recommended, as appropriate physical activity is beneficial for joint health and overall well-being. Increasing sugar intake (Choice C) is not a recommended practice for managing JIA, as a healthy diet is important for overall well-being and can help reduce inflammation. Using only oral medications (Choice D) may not be sufficient for managing JIA, as a comprehensive treatment plan often includes a combination of medications, physical therapy, and other interventions to effectively manage the condition.

2. What does the term 'essential nutrient' refer to?

A. A nutrient that can be synthesized by the body.
B. A nutrient that is required for proper body functioning.
C. A nutrient that must be obtained from the diet because the body cannot produce it.
D. A nutrient that can be stored in the body for long periods.

Correct answer: C

Rationale: The correct answer is C. An essential nutrient is a substance that is necessary for normal body functioning but cannot be synthesized in adequate amounts by the body, therefore it must be obtained from the diet. Choices A, B, and D are incorrect because essential nutrients are not synthesized by the body, they are necessary for body functioning, and they are not typically stored in the body for long periods.

3. How much energy is required to raise the temperature of one kilogram of water by 1°C?

A. 10 calories
B. 100 calories
C. 1 kilocalorie
D. 10 kilocalories

Correct answer: C

Rationale: The correct answer is 1 kilocalorie. This is the amount of energy required to raise the temperature of 1 kilogram of water by 1°C. Choice A (10 calories) and Choice D (10 kilocalories) are incorrect as they do not represent the correct unit of measurement for this specific scenario. Choice B (100 calories) is also incorrect as it overestimates the amount of energy required. The specific heat capacity of water is approximately 1 calorie/gram °C, which means that 1 kilogram (1000 grams) of water requires 1 kilocalorie (1000 calories) to raise its temperature by 1°C.

4. What is the primary purpose of a placebo in an experiment?

A. To reduce the cost of the experiment.
B. To make the experiment double-blind.
C. To increase the number of participants.
D. To serve as a control for comparison with the treatment group.

Correct answer: D

Rationale: The correct answer is D. A placebo serves as a control for comparison with the treatment group, helping to eliminate bias and ensure the results are due to the treatment itself. Placebos are crucial in research to distinguish the actual effect of the treatment from psychological or subjective factors. Choice A is incorrect because the purpose of a placebo is not related to reducing the cost of the experiment. Choice B is incorrect because while placebos are used in double-blind studies, their primary purpose is not to make the experiment double-blind. Choice C is incorrect because the purpose of a placebo is not to increase the number of participants but rather to serve as a comparison group for the treatment being tested.

5. What is the most common symptom of appendicitis in children?

A. Vomiting and diarrhea
B. Fever and abdominal pain
C. Rash and joint pain
D. Difficulty breathing

Correct answer: B

Rationale: The correct answer is B: Fever and abdominal pain. In children, appendicitis commonly presents with fever and abdominal pain. The pain typically begins around the umbilicus and then moves to the lower right quadrant. Choices A, C, and D are incorrect because vomiting and diarrhea, rash and joint pain, and difficulty breathing are not typical symptoms of appendicitis in children.
