Correct Answer: B

Rationale: The correct answer is B: Contact the elected representative's office by telephone to request support for the bill. This action is the most direct and effective way to influence the passage of the bill. By directly contacting the elected representative, the nurse can advocate for the importance of the bill and provide relevant information to garner their support. This direct communication with the decision-maker holds significant weight in influencing their vote on the bill. A: Explaining the rationale to the school board may be informative, but the school board may not have direct influence on the state legislature. C: Supporting a health advocate to run for election is a long-term strategy and may not have an immediate impact on the passage of the bill. D: Telling all students about the bill may raise awareness but may not directly influence the lawmakers' decisions.

Correct Answer: A

Rationale: The correct answer is A because large doses of calcium causing cerebral plaques to form can potentially mask the atrophy of the brain, which is a common indicator of dementia on imaging studies. This interference could delay the detection of dementia. Choice B is incorrect because excess folic acid would not mask a vitamin B deficiency that could lead to dementia. Choice C is incorrect as hypnotherapy focusing on current thoughts would not necessarily eliminate clues to past cognitive decline. Choice D is incorrect because there is no evidence that the electrical current from magnetic fields interferes with normal brain waves in a way that would cause confusion and inability to concentrate.

Correct Answer: A

Rationale: The correct answer is A: more secure. Electronic Health Records (EHR) typically have built-in security features such as encryption, access controls, and audit trails, making it more secure than paper-and-pencil records. EHRs offer better protection against unauthorized access, tampering, and loss compared to traditional paper records. This is due to the ability to restrict access to specific users, track changes made to the records, and implement authentication measures. Therefore, the security of EHRs surpasses that of paper-and-pencil records. Choices B, C, and D are incorrect because they do not acknowledge the enhanced security measures and advantages that EHRs provide over traditional paper records.

Correct Answer: B

Rationale: The most effective nursing leadership style in a crisis like this is democratic. In this situation, collaboration and input from all team members are essential for quick decision-making and effective communication. Democratic leadership promotes teamwork, empowers staff, and fosters open communication, leading to better coordination and outcomes. Autocratic leadership may hinder staff engagement and morale. Laissez-faire lacks direction and may result in chaos during a crisis. Referent leadership focuses on personal relationships rather than team dynamics, not the most effective approach in this urgent situation.

Correct Answer: B

Rationale: The correct answer is B: Hildegard E. Peplau. Peplau's nursing theory focuses on interpersonal relations, emphasizing the nurse-client relationship. In this situation, the client's anxiety and inability to participate in the diet plan are directly related to the negative interaction with the spouse. Peplau's theory suggests that the nurse can intervene by providing emotional support, facilitating communication, and helping the client manage anxiety. Rogers' theory focuses on the science of unitary human beings, which is not directly applicable here. Nightingale's theory emphasizes environmental factors, not interpersonal relationships. Levine's theory focuses on conservation principles, which are not directly relevant to addressing the client's anxiety and relational issues. Therefore, Peplau's theory best guides interventions in this situation.
