Question
![**Homework**
A 14-year-old girl with cystic fibrosis has complained of an increased cough productive of green sputum over the last week. She also complained of being increasingly short of breath, and she is noticeably wheezing on physical examination. Arterial blood was drawn and sampled, revealing the following values:
- **pH**: 7.30
- **pCO₂**: 50 mm Hg
- **pO₂**: 55 mm Hg
- **Hemoglobin - O₂ saturation**: 45%
- **[HCO₃⁻]**: 24 mEq/L
**Answer the following questions:**
1. What causes cystic fibrosis? Describe the pathophysiologic mechanisms of the disease.
2. Discuss the significance of the arterial blood gas values provided and propose a possible treatment plan based on these results.
This information can be utilized to understand the medical challenges associated with cystic fibrosis and guide further study into effective management strategies.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2077ee5b-ff5c-4f39-beec-ae97a8707f06%2Fead685b8-7d12-4e00-b927-123d03cd05e0%2Flztp13l_processed.jpeg&w=3840&q=75)
