Classifying the Severity of D.R. Asthma Attack According to D.R’s symptoms he would be classified under persistent mild asthma. His symptoms began four days ago, and his peak flow rates have maintained within 65%-70%, staying within the yellow zone. He has experienced three days with nighttime symptoms and albuterol usage has been indicated. Mild persistent asthma is indicated when symptoms have occurred greater than two days per week, nighttime symptoms are greater than two days a month and the utilization of short acting beta agonist such as albuterol is used greater than two days per week (Quirt et al, 2018). Common Triggers The most common triggers for asthma include dust mites, mold, pets, pollen, tobacco smoke, upper respiratory infections, stress, changes in weather or temperature, and exercise (Dlugasch & Story, 2021). In D.R.’s case I would consider the symptoms he is experiencing contribute to an upper respiratory infection such as rhinovirus. Viral infections such as rhinovirus contribute to asthma exacerbations due to the deterioration of epithelial tissue within the throat and nasal passages. This results in increased mucous production that will cause the airway to narrow and the chest to constrict from congestion (Ortega, Nickle & Carter, 2020). These symptoms induce asthmatic episodes and can result in exacerbations. Etiology of D.R.’s Asthma There are many possible etiologies that can be the cause of D.R. being asthmatic. He could possibly have a family or genetic history that predisposes him to having asthma as it has been found that family history combined with environmental factors enhance the likelihood of asthma development (book). It may be related to D.R.s occupational status or environment as exaggerated IGE responses to allergens and irritants such as pollen, smoking, chemicals or dust can cause asthma (Dlugasch & Story, 2021). Case Study 2 Laboratory Values According to Ms.Brown’s laboratory values it can be determined that she has hyperglycemia, hypernatremia, hyperkalemia, hyperchloremia. The ABG results indicate metabolic acidosis. Signs and Symptoms of The Water Imbalances Hypernatremia manifestations include lethargy, headache, confusion, irritability, seizures, coma, hypovolemia, dry mucous membranes, thirst and decreased urine output. Hyperchloremia does not have clinical manifestations but can be seen within the signs and symptoms of metabolic acidosis. Ms.Brown may demonstrate clinical manifestations of hyperkalemia such as hyperreflexia, flaccid paralysis, anxiety, nausea, vomiting, dysrhythmias, cardiac arrest, respiratory depression and respiratory arrest (Dlugasch & Story, 2021). Treatment Due to Ms. Brown’s elevated potassium level aggressive treatment is needed in order to correct the electrolyte imbalance. Multiple treatment courses are available, and they include providing calcium therapy in order to prevent cardiac toxicity. Cardiac gluconate is the initial drug of choice. Calcium chloride can be pr.
