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: Mitigation is not the correct level of the National Response Framework, as it refers to the actions taken to reduce or eliminate the long-term risk to human life and property from natural or man-made hazards. Mitigation activities include implementing building codes, zoning ordinances, land use planning, and flood insurance programs. Mitigation is a continuous process that occurs before, during, and after a disaster.

Choice B reason: Security is not the correct level of the National Response Framework, as it refers to the actions taken to protect the nation from threats or attacks by terrorists, criminals, or hostile states. Security activities include conducting intelligence operations, screening travelers and cargo, enforcing laws and regulations, and preventing cyberattacks. Security is a shared responsibility among federal, state, local, tribal, territorial, and private sector partners.

Choice C reason: Preparedness is the correct level of the National Response Framework, as it refers to the actions taken to plan, organize, equip, train, and exercise to build and sustain the capabilities necessary to prevent, protect against, mitigate the effects of, respond to, and recover from those threats that pose the greatest risk. Preparedness activities include developing emergency plans, conducting drills and exercises, educating the public, and establishing partnerships and coordination mechanisms. Preparedness is a continuous cycle of improvement that involves assessing needs, setting goals, implementing plans, and evaluating outcomes.

Choice D reason: The response phase is not the correct level of the National Response Framework, as it refers to the actions taken to save lives, protect property and the environment, stabilize the situation, and meet basic human needs in the immediate aftermath of a disaster. Response activities include activating emergency operations centers, deploying resources and personnel, providing mass care and sheltering, restoring critical infrastructure and services, and conducting search and rescue operations. Response is a short-term process that aims to restore normalcy as soon as possible.

Choice A reason: Mitral valve disease is not a disorder that makes clients especially vulnerable to ozone effects, as it does not affect the respiratory system. Mitral valve disease is a condition that affects the mitral valve, which is the valve that separates the left atrium and the left ventricle of the heart. Mitral valve disease can cause the valve to become narrow (stenosis) or leaky (regurgitation), affecting the blood flow and oxygen delivery to the body. Mitral valve disease can cause symptoms such as shortness of breath, fatigue, chest pain, palpitations, and swelling of the legs.

Choice B reason: Asthma is a disorder that makes clients especially vulnerable to ozone effects, as it affects the respiratory system. Asthma is a chronic inflammatory condition that causes the airways to become narrow, swollen, and sensitive to triggers such as allergens, irritants, infections, or exercise. Asthma can cause symptoms such as wheezing, coughing, chest tightness, and difficulty breathing. Ozone is a gas that is formed when sunlight reacts with pollutants in the air. Ozone can irritate the lungs and worsen asthma symptoms by causing inflammation, bronchoconstriction, and mucus production. Ozone can also reduce lung function and increase the risk of respiratory infections.

Choice C reason: Nasal polyps are not a disorder that makes clients especially vulnerable to ozone effects, as they do not affect the respiratory system. Nasal polyps are benign growths that form in the lining of the nose or sinuses. Nasal polyps can cause symptoms such as nasal congestion, runny nose, postnasal drip, loss of smell or taste, headache, and snoring. Nasal polyps are usually associated with chronic inflammation or allergies, but their exact cause is unknown.

Choice D reason: Seasonal allergies are not a disorder that makes clients especially vulnerable to ozone effects, as they do not affect the respiratory system. Seasonal allergies are allergic reactions that occur during certain times of the year when pollen or mold spores are high in the air. Seasonal allergies can cause symptoms such as sneezing, itching, watery eyes, runny nose, and sore throat. Seasonal allergies are caused by an overreaction of the immune system to harmless substances in the environment.
