What genetic disorder is characterized by affecting the respiratory and digestive systems?

• A. Huntington's disease
• B. Cystic fibrosis
• C. Muscular dystrophy
• D. Hemophilia

Answer: (B)

Cystic fibrosis is a genetic disorder caused by mutations in the CFTR gene, leading to the production of thick and sticky mucus in various organs. It primarily impacts the respiratory and digestive systems. In the respiratory system, the mucus obstructs the airways, making it difficult to breathe and leading to recurrent lung infections. In the digestive system, the thick mucus can block pancreatic enzymes from reaching the intestines, resulting in nutrient malabsorption and digestive complications.

This disorder exemplifies how a single genetic mutation can have widespread effects on different organ systems, emphasizing the importance of understanding systemic implications in nursing care. Recognizing the signs and symptoms of cystic fibrosis is essential for early diagnosis and management, which can significantly improve the quality of life for affected individuals.
