Pulmonary Function:
D.R. is a 27-year-old man, who presents to the nurse practitioner at the Family Care Clinic complaining of increasing SOB, wheezing, fatigue, cough, stuffy nose, watery eyes, and postnasal drainage—all of which began four days ago. Three days ago, he began monitoring his peak flow rates several times a day. His peak flow rates have ranged from 65-70% of his regular baseline with nighttime symptoms for 3 nights on the last week and often have been at the lower limit of that range in the morning. Three days ago, he also began to self-treat with frequent albuterol nebulizer therapy. He reports that usually his albuterol inhaler provides him with relief from his asthma symptoms, but this is no longer enough treatment for this asthmatic episode.
Case Study Questions
According to the case study information, how would you classify the severity of D.R. asthma attack?
Name the most common triggers for asthma in any given patients and specify in your answer which ones you consider applied to D.R. on the case study.
Based on your knowledge and your research, please explain the factors that might be the etiology of D.R. being an asthmatic patient.
Full Answer Section
Common Asthma Triggers and Potential Triggers for D.R.:
Several common triggers can trigger asthma attacks, including:
- Allergens: Dust mites, pollen, mold, pet dander
- Irritants: Smoke, air pollution, strong odors, cleaning chemicals
- Respiratory infections: Colds, flu, bronchitis
- Physical exercise
- Emotional stress and anxiety
Based on the case study, potential triggers for D.R. could be:
- Upper respiratory infection: His stuffy nose, watery eyes, and postnasal drainage suggest a possible infection triggering the attack.
- Stress: While not mentioned, stress can be a common trigger worth considering.
Etiology of D.R.'s Asthma:
Determining the exact cause of his asthma is difficult without further information. However, several factors contribute to asthma development:
- Genetics: Family history of asthma increases the risk.
- Environmental factors: Exposure to allergens and irritants can trigger inflammation and airway narrowing.
- Immune system dysfunction: Imbalances in the immune response can contribute to asthma.
- Early life factors: Viral infections, childhood respiratory illnesses, and exposure to tobacco smoke can increase the risk.
In D.R.'s case, knowing:
- Family history of asthma: Could point towards a genetic predisposition.
- Occupational exposure: Certain workplaces can harbor triggers like dust or chemicals.
- Smoking history: Smoking is a significant risk factor for asthma.
Knowing these details would provide a more comprehensive understanding of D.R.'s asthma etiology.
