Which medication should the nurse anticipate being used first in the emergency department for relief of severe respiratory distress related to asthma?
Albuterol nebulizer
Prednisone orally
Ipratopium inhaler
Fluticasone inhaler
The Correct Answer is A
Albuterol is a short-acting beta-agonist bronchodilator that provides rapid relief of bronchospasm and helps to alleviate the symptoms of respiratory distress in asthma. It acts quickly to relax the smooth muscles in the airways, improving airflow and relieving wheezing, coughing, and shortness of breath. In an acute asthma exacerbation, albuterol is often the first-line medication used to provide immediate relief and improve respiratory function. Prednisone is an oral corticosteroid that has anti-inflammatory effects and is commonly used in the treatment of asthma. However, it is typically administered orally and takes time to exert its effects. In the emergency department setting, the focus is on providing immediate relief of symptoms, and oral medications like prednisone may not have an immediate effect. Ipratropium is an anticholinergic bronchodilator that can be administered via inhalation. While it is effective in relieving bronchospasm, it is generally used as an adjunct to albuterol and not typically the first-line medication for severe respiratory distress in asthma. Fluticasone is an inhaled corticosteroid that has anti-inflammatory effects and is used for long-term management and control of asthma. It is not appropriate for immediate relief of severe respiratory distress and is not typically used as a first-line medication in the emergency department.

Correct Answer is C
Explanation
Excessive exposure to UV light, such as sunlight or tanning beds, is a known trigger for SLE exacerbations. It is important for individuals with SLE to protect their skin from the sun by wearing protective clothing, using sunscreen, and avoiding direct sunlight during peak hours. Having a family history of SLE increases the risk of developing the disease. While it is not a trigger in itself, it is an important piece of information for the client to be aware of, as it may indicate a genetic predisposition to the condition.
Acetaminophen is a commonly used over-the-counter pain reliever. While it can help manage pain associated with SLE, it is not typically considered a trigger for exacerbations. Menopause, which marks the end of a woman's reproductive years, does not directly trigger SLE exacerbations. However, hormonal changes during menopause can potentially affect disease activity in some individuals. It is important for the client to discuss any changes or concerns with their healthcare provider to manage their symptoms effectively.
Correct Answer is B
Explanation
Antihistamines primarily work by blocking the H1 receptors, which are the receptors responsible for mediating the actions of histamine in the body. By blocking these receptors, antihistamines prevent or reduce the effects of histamine, such as itching, sneezing, runny nose, and watery eyes. This is the main mechanism by which antihistamines provide their therapeutic effects. "Antihistamines block release of histamine from mast cells and basophils." This statement is incorrect. Antihistamines do not block the release of histamine; instead, they block the histamine receptors to prevent the effects of histamine.
"H1 antagonists can bind to H1 receptors, H2 receptors, and muscarinic receptors." This statement is incorrect. H1 antagonists, or H1 receptor blockers, specifically bind to H1 receptors and do not have significant affinity for H2 receptors or muscarinic receptors. "First-generation antihistamines are more selective than second-generation antihistamines." This statement is incorrect. First-generation antihistamines are generally less selective and can have more sedating and anticholinergic effects compared to second-generation antihistamines, which are designed to be more selective for H1 receptors and have reduced sedative properties.
