Correct Answer: B

Rationale: The correct answer is B because in a mass casualty disaster following a terrorist attack, the same ground rules practiced in other settings and during smaller crises will be applicable. This is because the scale and complexity of the disaster require established protocols and procedures to manage the situation effectively. Choice A is incorrect because the response of local hospitals may not necessarily be dictated by the federal government in such situations. Choice C is incorrect because assigning the least experienced nurses to triage patients based on their perceived risk or chances of survival is not ethical or effective. Choice D is incorrect because having multiple incident commanders can lead to confusion and delays in decision-making during a crisis.

Correct Answer: A

Rationale: The correct answer is A because "meaningful use" standards in EHR refer to specific criteria that healthcare providers must meet to receive incentives for using EHR effectively. This includes improving quality, safety, efficiency, and reducing health disparities. By meeting these benchmarks, providers can qualify for funds from Medicare. Choice B is incorrect because "meaningful use" is not just about training competencies but about how EHR systems are used to improve patient care. Choice C is incorrect as it misinterprets the concept of meaningful use. It is not about a specific percentage of patients with data entered, but about the overall impact of EHR on healthcare delivery. Choice D is incorrect because while confidentiality and security are important aspects of EHR, they are not the sole focus of meaningful use standards.

Correct Answer: A

Rationale: The correct answer is A: deployment flowchart. A deployment flowchart is a visual representation that outlines the steps involved in a specific process, making it ideal for the nurse to follow when administering medication at the vastus lateralis site. It provides a detailed, step-by-step guide, ensuring the process is carried out accurately and safely. Explanation of other choices: B: Top-down flowchart - This type of flowchart shows the hierarchy or sequence of steps in a process but may not provide the specific details needed for the nurse's task. C: Pareto chart - A Pareto chart is used to prioritize and identify the most significant factors in a process, not suitable for providing step-by-step instructions. D: Control plot - This term is not related to providing detailed instructions for a process, making it an incorrect choice.

Correct Answer: B

Rationale: The correct answer is B: Level B. In a scenario involving Sarin, a highly toxic nerve agent primarily inhaled, Level B protective equipment is required. Level B PPE includes a chemical-resistant suit, chemical-resistant gloves, chemical-resistant boots, and a full-face respirator with appropriate filter cartridges. The choice of Level B is based on the fact that Sarin is primarily inhaled, indicating the need for respiratory protection. Level A is typically used for the highest level of protection, including protection against highly toxic chemicals in both the air and on the skin, which is not necessary in this scenario. Level C and D do not provide adequate protection against a highly toxic chemical like Sarin.

Correct Answer: B

Rationale: The correct answer is B: National Council of State Boards of Nursing (NCSBN). NCSBN manages the Nurse Licensure Compact (NLC), which allows nurses to practice in compact states without obtaining additional licenses. Nurses can find a list of current compact states on the NCSBN website. NLN (A) focuses on nursing education, not regulation. AACN (C) is an organization for academic nursing programs. CCNE (D) accredits nursing education programs, not regulatory information.
