Correct Answer: D

Rationale: The correct answer is D because prioritizing care based on the greatest chance of survival maximizes the number of lives saved in a mass casualty incident. This approach follows the principle of triage, which aims to allocate resources efficiently. Choice A is incorrect as it pertains to coordination rather than immediate patient care. Choice B is incorrect as it is not the primary role of nurses during a mass casualty incident. Choice C is incorrect as determining a credible threat is the responsibility of security and law enforcement, not nurses.

Correct Answer: A

Rationale: The correct answer is A: Safety. The team of nurses developing algorithms and checklists aims to ensure standardization of procedures, which directly relates to patient safety. Safety is a fundamental competency in healthcare, as it involves minimizing harm to patients. Standardization through checklists helps reduce errors and promote consistency in care delivery. Timely care (B) focuses on providing care promptly, equitable care (C) emphasizes fairness and eliminating disparities, and patient-centered care (D) prioritizes individual preferences and needs. While these competencies are important in healthcare, in this scenario, the team's primary focus on standardization aligns with the safety competency.

Correct Answer: D

Rationale: Step 1: Acknowledge the clinical expertise of the upset nurse - This shows respect for the upset nurse's experience and expertise. Step 2: Clearly explain the expectations for teamwork - Setting clear expectations fosters a collaborative environment. Step 3: Emphasize open, honest communication - Encouraging open dialogue helps address concerns and build trust among the team. Overall, option D is the best approach as it combines acknowledging the upset nurse's expertise, setting expectations for teamwork, and promoting open communication, which are crucial for gaining trust and respect among the nursing staff. Summary of other choices: A: Sending memos excludes the upset nurse and may create further resentment. B: Transferring the upset nurse does not address the issue and may lead to more conflict. C: Assigning the upset nurse to unrelated committees may isolate them and not address the underlying problem of lack of trust and respect on the unit.

Correct Answer: C

Rationale: The correct answer is C. When delegating tasks to an LPN/LVN, the RN must review the state's nurse practice act because each state defines the role and scope of practice of the LPN/LVN. This is crucial as the LPN/LVN scope of practice can vary significantly from state to state. By reviewing the nurse practice act, the RN ensures that the tasks being delegated fall within the legal scope of practice for the LPN/LVN in that specific state, promoting safe and effective patient care. Choice A is incorrect because the role of the LPN/LVN can differ between states. Choice B is incorrect because LPN/LVNs cannot perform all duties of an RN, and additional training does not change their scope of practice. Choice D is incorrect because the Joint Commission does not establish roles for LPN/LVNs; it focuses on accreditation standards for healthcare organizations.

Correct Answer: B

Rationale: The correct answer is B: randomization. Randomization helps ensure improved generalizability by reducing bias and increasing the likelihood that the sample is representative of the population. In this scenario, choosing every third person from an alphabetical list introduces a systematic bias and may not represent the entire population accurately. Triangulation involves using multiple methods or data sources to validate findings, which is not applicable here. Informed consent is a necessary ethical consideration but does not directly impact generalizability. A meta-analysis approach involves combining and analyzing data from multiple studies, which is not relevant to the sampling method in this scenario. Thus, randomization is the best choice to improve generalizability in this study.
