What is the appropriate intervention for a child with an undescended testicle?
- A. Wait until puberty
- B. Perform an orchidopexy
- C. Administer hormone therapy
- D. Increase physical activity
Correct Answer: B
Rationale: The appropriate intervention for a child with an undescended testicle is to perform an orchidopexy. This surgical procedure is recommended if the testicle has not descended naturally within the first year of life. Waiting until puberty is not advised as early intervention is crucial for optimal outcomes. Administering hormone therapy is not the first-line treatment for an undescended testicle and is typically not recommended. Increasing physical activity does not address the underlying issue of an undescended testicle and is not a suitable intervention.

Your friend Carrie took a daily supplement of vitamin C and tells you that she feels a lot better. Her statement to you is best described as what?
- A. an anecdote
- B. theory
- C. interpretation
- D. conclusion
Correct Answer: A
Rationale: The correct answer is A, 'an anecdote.' An anecdote is a personal account or experience, not necessarily backed by scientific evidence. In this case, Carrie's statement about feeling better after taking vitamin C is based on her personal experience and does not constitute scientific evidence or a generalizable conclusion. Choice B, 'theory,' would imply a systematic explanation based on scientific evidence, which is not the case here. Choice C, 'interpretation,' typically involves explaining or understanding something based on available information, not a personal account. Choice D, 'conclusion,' would be a general statement derived from specific information or facts, which is not applicable in this context.
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.

What is a common side effect of corticosteroid therapy in children?
- A. Increased appetite
- B. Decreased blood glucose levels
- C. Inhibited growth
- D. Mood changes

Option B is incorrect because corticosteroid therapy is more likely to result in increased blood glucose levels. Option C is incorrect because corticosteroid therapy can inhibit growth due to its impact on the endocrine system. Option D is incorrect because corticosteroid therapy can lead to mood changes such as irritability or even mood swings rather than improved mood.

- A. minerals
- B. proteins
- C. alcohols
