Final answer:
A child with an arm fracture and cystic fibrosis has one acute and one chronic condition. Cystic fibrosis is an autosomal recessive genetic disease affecting the lungs and digestive system, with improved life expectancy thanks to medical advancements.
Step-by-step explanation:
A child with a fractured arm and cystic fibrosis is suffering from two distinct medical conditions. The fractured arm is a temporary condition resulting from an injury to the bone that will heal over time, whereas cystic fibrosis is a chronic, inherited disorder. Cystic fibrosis is an autosomal recessive genetic disease that leads to the production of thick, sticky mucus that can clog various organs, predominantly the lungs and digestive system. Due to advancements in medical treatment, the life expectancy of those with CF has significantly improved, with many living into their 30s and beyond. However, it remains a serious condition that requires ongoing medical care to manage symptoms and maintain quality of life.
