Correct Answer: A

Rationale: The correct answer is A: utilitarianism. Utilitarianism is an ethical principle that focuses on maximizing overall well-being and minimizing harm. In this scenario, the decision to provide extended care to the two critical individuals with life-threatening injuries aligns with utilitarianism as it prioritizes saving the most lives and reducing suffering. By choosing to allocate resources to those with the most severe injuries, the healthcare providers are aiming to maximize the overall benefit to society. Summary of why the other choices are incorrect: B: Deontology focuses on following rules and duties regardless of the consequences. In this case, the decision to provide care based on severity of injuries goes against a strict deontological approach. C: Autonomy emphasizes respecting individuals' rights to make their own decisions about their care, which is not the primary consideration in this scenario. D: Veracity pertains to honesty and truthfulness in communication, which is not directly relevant to the decision-making process in this healthcare scenario.

Correct Answer: D

Rationale: The correct answer is D: National Disaster Medical System (NDMS). This system is designed to provide medical care during disasters, including addressing mental health needs like posttraumatic stress syndrome in victims and compassion fatigue in care providers. NDMS coordinates federal medical response resources and personnel to support communities during disasters. A: Strategic National Stockpile focuses on providing medicines, vaccines, and medical supplies, but does not directly address mental health needs or provide medical care. B: Metropolitan Medical Response System (MMRS) focuses on local response capabilities for mass casualty incidents, but does not have the same scope as NDMS in providing comprehensive medical care. C: Commissioned Corps Readiness Force is a team of healthcare professionals within the U.S. Public Health Service, but it is not specifically designated for disaster medical response like NDMS.

Correct Answer: C

Rationale: The correct answer is C: credible threat. In this scenario, a credible threat refers to a specific and tangible indication that a harmful event may occur. The information provided by the FBI about a bomb in possession of a known terrorist group targeting government buildings is a clear example of a credible threat. This term is specifically used in emergency management to indicate a situation where there is a realistic possibility of harm. A is incorrect because an all-hazards approach involves preparing for and responding to a wide range of potential disasters, not specifically a bomb threat. B is incorrect because a biologic event refers to an outbreak of a biological agent, not a bomb threat. D is incorrect because a natural disaster involves events caused by natural forces, not intentional acts by terrorist groups.

Correct Answer: C

Rationale: The correct answer is C: Trager approach. This treatment involves gentle rocking and rhythmic motions to release tension in muscles and joints. The goal is to improve mobility and reduce pain. The other choices are incorrect because: A: Swedish massage focuses on kneading and rubbing muscles, not specifically on rhythmic motions to release tension. B: Rolfing is a deep tissue manipulation technique aimed at realigning the body's structure, not specifically utilizing rocking and rhythmic motions. D: Reflexology involves applying pressure to specific points on the hands, feet, or ears to promote healing, not utilizing rocking and rhythmic motions.

Correct Answer: B

Rationale: The correct answer is B: Informatics. Nurses on the orthopedic unit are demonstrating informatics competency by using PDAs for medication review and accessing video clips for procedures. This showcases their ability to utilize technology to enhance patient care. Patient-centered care (A) focuses on individualized care, teamwork (C) emphasizes collaboration, and quality improvement (D) pertains to enhancing processes. The use of technology in this scenario aligns most closely with the informatics competency, making it the best choice.
