A client diagnosed with trigeminal neuralgia is experiencing intermittent, sudden, severe pain on the left side of the face. The nurse identifies which classification of medications is most effective in treating this pain.

Choice A reason: Continuing with the triage process is not an immediate intervention that needs to be taken by the triage nurse, as it may expose more people to the chemical hazard and worsen the situation. The triage nurse should stop the triage process and alert the emergency department staff and management about the potential contamination. The triage nurse should also follow the facility's emergency preparedness plan and protocols for dealing with chemical spills.

Choice B reason: Evacuating the emergency department is an immediate intervention that needs to be taken by the triage nurse, as it helps to protect the safety and health of the staff, clients, and visitors. The triage nurse should assist with evacuating everyone from the emergency department to a safe and designated area, away from the source of contamination. The triage nurse should also ensure that everyone is accounted for and that no one re-enters the emergency department until it is cleared by the authorities.

Choice C reason: Placing the client in a private room is not an immediate intervention that needs to be taken by the triage nurse, as it may not prevent the spread of contamination or provide adequate care to the client. The client who have been exposed to a chemical spill should not be moved to another area of the facility, as they may contaminate other people or surfaces along the way. The client should be kept in a separate and isolated area until they are decontaminated and assessed.

Choice D reason: Treating the client after contaminated items are removed is not an immediate intervention that needs to be taken by the triage nurse, as it may delay or compromise the care of the client. The client who has been exposed to a chemical spill should be treated as soon as possible, as some chemicals can cause serious or irreversible damage to the skin, eyes, lungs, or other organs. The triage nurse should provide basic life support measures, such as airway management, oxygen therapy, or bleeding control while wearing appropriate personal protective equipment (PPE). The triage nurse should also remove any contaminated clothing or jewelry from the client and place them in a sealed bag.

Choice E reason: Sending the client and EMS crew to decontamination is an immediate intervention that needs to be taken by the triage nurse, as it helps to remove or neutralize any harmful chemicals from their skin, hair, or clothing. The triage nurse should direct or escort the client and EMS crew to a designated decontamination area or unit, where they will undergo a thorough washing process with water and soap or other solutions. The triage nurse should also monitor their vital signs and symptoms during and after decontamination.

Choice A: Encourage community members to practice fire drills. This is incorrect because fire drills are a part of the preparedness phase, not the prevention/mitigation phase. The prevention/mitigation phase aims to reduce the risk and impact of disasters, while the preparedness phase aims to enhance the readiness and response capacity of individuals and communities.

Choice B: Identify community members who have disabilities. This is incorrect because identifying community members who have disabilities is also a part of the preparedness phase, not the prevention/mitigation phase. The prevention/mitigation phase focuses on actions that can prevent or minimize the occurrence or effects of disasters, such as installing smoke detectors, reinforcing buildings, or creating evacuation routes.

Choice C: Provide first aid to community members affected by a tornado. This is incorrect because providing first aid to community members affected by a tornado is a part of the response phase, not the prevention/mitigation phase. The response phase involves immediate actions to save lives, protect property, and meet basic needs after a disaster occurs.

Choice D: Assist community members in developing a disaster plan. This is correct because assisting community members in developing a disaster plan is a part of the prevention/mitigation phase. A disaster plan can help identify potential hazards, assess vulnerabilities, establish goals and objectives, and implement strategies to reduce the risk and impact of disasters.
