A nurse providing care at the bedside receives an "alert" that a patient's stat potassium level is 5 and digoxin (Lanoxin) is scheduled. The nurse holds the medication and prevents a possible complication. This feature of the Electronic Health Record is available through which core function of EHR?

Correct Answer: B

Rationale: The correct answer is B: Decision support. In this scenario, the nurse received an alert regarding a potential drug interaction between the patient's potassium level and the scheduled digoxin. Decision support in EHR provides real-time clinical guidance to healthcare providers, helping them make informed decisions to improve patient safety. Holding the medication in response to the alert demonstrates the effective use of decision support to prevent adverse drug events. Choices A, C, and D do not directly relate to the situation described and do not involve the clinical decision-making support provided by EHRs.

Correct Answer: A

Rationale: The correct answer is A because during the relief response phase of a "dirty bomb" disaster, victims are likely to suffer from burns and poisoning due to radiation exposure. Providing treatment for burns and poisoning is crucial to saving lives and preventing further health complications. Choice B is incorrect because emergency plans coordination typically occurs during the preparedness phase, not the relief response phase. Choice C is incorrect as reconstruction usually takes place in the recovery phase, which follows the relief response phase. Choice D is incorrect as collecting food stores is more related to preparedness or immediate response, not specifically during the relief response phase.

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: A

Rationale: The correct answer is A because in a mass casualty incident, triage principles dictate that care should be prioritized to those with the greatest chance of survival to maximize overall survival rates. This ensures that limited resources are used efficiently. Choices B, C, and D are incorrect: B: Using only community resources first may not be sufficient in a large-scale disaster and could delay the response, leading to unnecessary loss of life. C: State assistance may not be automatically available in every disaster situation and is typically coordinated based on the severity and impact of the disaster. D: Emergency operating plans should be tailored to individual facilities' needs and capabilities, as a one-size-fits-all approach may not be effective in all scenarios.
