What is the most appropriate intervention for the school nurse to implement to promote a healthy school environment?

Correct Answer: A

Rationale: The correct answer is A: Advocate for nutritious school lunch programs. This intervention promotes a healthy school environment by ensuring students have access to nutritious meals, which are essential for their overall health and well-being. By advocating for nutritious school lunch programs, the school nurse can help improve students' physical health, cognitive functioning, and overall academic performance. This intervention also aligns with the school nurse's role in promoting preventive health measures. Summary: B: Providing care for children with asthma is important but does not address the broader goal of promoting a healthy school environment. C: Developing individualized health plans is beneficial for specific students but may not impact the overall school environment. D: Educating students and families about screening for scoliosis is important for early detection but does not directly contribute to creating a healthy school environment.

Correct Answer: C

Rationale: The correct answer is C because the Nurse Practice Act is a state law that defines the scope of practice for nurses, including school nurses. This law outlines the specific duties, responsibilities, and limitations of nurses in that state, ensuring they practice safely and within legal boundaries. Choice A is incorrect as it doesn't address the legal framework. Choice B is incorrect because the Nurse Practice Act supersedes any job description set by the school district. Choice D is incomplete and irrelevant to the question.

Correct Answer: B

Rationale: The correct answer is B because administering medication for the treatment of hepatitis C falls under tertiary health promotion, which focuses on managing and treating long-term diseases to prevent complications. Teaching rescue inhaler use (A) is more related to secondary prevention. Advocating for low-sodium dietary options (C) and recommending physical therapy (D) are examples of primary prevention strategies.

Correct Answer: D

Rationale: The correct answer is D (A and C). Independent assortment of chromosomes occurs during meiosis when homologous chromosomes separate randomly, leading to genetic variation in offspring. Recombination, or crossing over, also occurs during meiosis when genetic material is exchanged between homologous chromosomes, further increasing genetic diversity. Mutation (choice B) can occur in both sexual and asexual reproduction, so it is not specific to sexual reproduction. Choice D is correct because both independent assortment and recombination are unique mechanisms of genetic change in sexual reproduction, leading to genetic variation in offspring.

Correct Answer: A

Rationale: The genetic code is redundant because different codons can specify the same amino acid. This redundancy provides a buffer against mutations, ensuring that a change in a single nucleotide does not always result in a change in the amino acid being coded for. This redundancy allows for error correction during translation, increasing the robustness of the genetic code. Choices B, C, and D are incorrect because the redundancy in the genetic code is primarily for ensuring accuracy and reliability in protein synthesis, not for developing new amino acids or non-coding signals.
