Answer to Question 1

ANS: A
The earliest clinical manifestation of CF is a meconium ileus, which is found in about 10 of children with CF. Clinical manifestations include abdominal distention, vomiting, failure to pass stools, and rapid development of dehydration. History of malabsorption is a later sign that manifests as failure to thrive. Foul-smelling stools are a later manifestation of CF. Recurrent respiratory tract infections are a later sign of CF.

Answer to Question 2

ANS: A
CF is an autosomal recessive gene inherited from both parents and is inherited as an autosomal recessive, not autosomal dominant, trait. CF is found primarily in Caucasian populations. An autosomal recessive inheritance pattern means that there is a 25 chance a sibling will be infected but a 50 chance a sibling will be a carrier.
