A community health nurse is conducting an educational program on various environmental pollutants. The nurse should emphasize that clients who have which of the following disorders are especially vulnerable to ozone effects?

Mitral valve disease

Asthma

Nasal polyps

Seasonal allergies

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is C

Explanation

Choice A reason: A negative-pressure isolation room is not a suitable room for a client who has scabies. A negative-pressure isolation room is used for clients who have airborne infections, such as tuberculosis or chickenpox. It prevents the contaminated air from escaping the room and infecting other people.

Choice B reason: A positive-pressure isolation room is not a suitable room for a client who has scabies. A positive-pressure isolation room is used for clients who have compromised immune systems, such as those undergoing bone marrow transplants or chemotherapy. It prevents the outside air from entering the room and exposing the client to germs.

Choice C reason: A private room is a suitable room for a client who has scabies. Scabies is a skin infection caused by tiny mites that burrow under the skin and cause intense itching and rash. Scabies can spread easily through direct skin-to-skin contact or sharing personal items, such as clothing or bedding. A private room can prevent the transmission of scabies to other clients or staff.

Choice D reason: A semi-private room with a client who has pediculosis capitis is not a suitable room for a client who has scabies. Pediculosis capitis is an infestation of head lice that feeds on human blood and causes itching and irritation on the scalp. Pediculosis capitis can also spread easily through direct contact or sharing personal items, such as combs or hats. Sharing a room with another client who has pediculosis capitis can increase the risk of cross-infection and complicate the treatment of both conditions.

A. Black tag B. Red tag C. Green tag D. Yellow tag

Correct Answer is B

Explanation

Choice A reason: A black tag is not the appropriate priority tag for this client, as it indicates that the client is dead or has injuries that are incompatible with life. A black tag is used for clients who have no signs of life, such as pulse, respiration, or pupillary response, or who have severe injuries that cannot be treated with the available resources, such as massive head trauma, decapitation, or incineration. A black tag means that no further care or intervention is provided to the client.

Choice B reason: A red tag is the appropriate priority tag for this client, as it indicates that the client has life-threatening injuries that require immediate attention and treatment. A red tag is used for clients who have compromised airway, breathing, or circulation, such as respiratory distress, shock, severe bleeding, chest pain, or head injury. A red tag means that the client is given the highest priority and is treated as soon as possible.

Choice C reason: A green tag is not the appropriate priority tag for this client, as it indicates that the client has minor injuries that do not require urgent care or intervention. A green tag is used for clients who have stable vital signs and can walk or move without assistance, such as abrasions, sprains, fractures, or minor burns. A green tag means that the client is given the lowest priority and is treated after all other clients.

Choice D reason: A yellow tag is not the appropriate priority tag for this client, as it indicates that the client has serious injuries that require observation and treatment within a short time frame. A yellow tag is used for clients who have potential complications or deterioration of their condition, such as abdominal pain, pelvic injury, open wounds, or spinal injury. A yellow tag means that the client is given the second highest priority and is treated within 30 to 60 minutes.
