Answer to Question 1

A hematoma behind the ear over the mastoid bone would be documented as Battle's sign and is an indication of head trauma to the temporal bone. This is not a normal finding. Battle's sign is caused by head trauma to the temporal bone and not by sun exposure. Perichondritis is inflamed connective tissue of the ear cartilage.

Answer to Question 2

Cystic fibrosis is an inherited, autosomal recessive disease that is passed on by a defective gene from both parents and not one parent. This disease does not occur because of an extra chromosome. This disease is not an X-linked disorder. Cystic fibrosis is a chronic, progressive, and frequently fatal disease of the body's exocrine mucus-producing glands that primarily affects the respiratory, digestive, intestinal systems, and the pancreas.
