The nurse is caring for a child who was recently diagnosed with moderate persistent asthma. Which common asthma triggers should the nurse teach the client to avoid?

Cigarettes or tobacco smoke

Air pollution

Any physical activity

Certain cough products

Answer and Explanation

Correct Answer : A,B,D

Choice A reason: Cigarette or tobacco smoke is a major trigger for asthma attacks. Inhaling smoke irritates the airways, leading to inflammation and bronchoconstriction, making it harder for asthmatic individuals to breathe.

Choice B reason: Air pollution, including smog, industrial emissions, and vehicle exhaust, can exacerbate asthma symptoms. Pollutants in the air can trigger airway inflammation and constriction, leading to asthma attacks.

Choice C reason: Physical activity is not a common trigger for moderate persistent asthma if managed properly. Regular exercise is generally encouraged for overall health and can help improve lung function. However, clients should use their prescribed inhaler and follow their asthma action plan to manage exercise-induced asthma symptoms.

Choice D reason: Certain cough products, especially those containing ingredients like menthol or chemicals, can irritate the airways and trigger asthma symptoms. It's important for clients with asthma to avoid using over-the-counter cough products without consulting their healthcare provider.

Correct Answer is B

Explanation

Choice A reason: Sodium bicarbonate is used to treat metabolic acidosis and is not indicated for symptomatic bradycardia.

Choice B reason: Atropine is the first-line medication for symptomatic bradycardia. It works by blocking the vagus nerve's effects on the heart, increasing heart rate. It is commonly used in emergency settings to manage bradycardia until a more definitive treatment, such as pacemaker insertion, can be provided.

Choice C reason: Magnesium is typically used to treat torsades de pointes, a specific type of ventricular tachycardia, and is not indicated for symptomatic bradycardia.

Choice D reason: Amiodarone is an antiarrhythmic medication used to manage various types of arrhythmias, including ventricular tachycardia and fibrillation, but it is not indicated for symptomatic bradycardia.

A. Blood urea nitrogen B. Hematocrit C. Brain natriuretic peptide (BNP) D. Hemoglobin

Correct Answer is C

Explanation

Choice A reason: Blood urea nitrogen (BUN) levels are used to assess kidney function and are not specific to heart failure.

Choice B reason: Hematocrit levels indicate the proportion of red blood cells in the blood and are not specific to heart failure. They are used to assess anemia and other blood disorders.

Choice C reason: Brain natriuretic peptide (BNP) levels are elevated in heart failure. BNP is released by the ventricles in response to increased pressure and volume overload. Monitoring BNP levels helps assess the severity of heart failure and the effectiveness of treatment.

Choice D reason: Hemoglobin levels indicate the oxygen-carrying capacity of the blood and are used to assess anemia but are not specific to heart failure.
