This is a question in the manual (with the answer):
Which of the following statements about cystic fibrosis is true?
a) it is inherited as an autosomal dominant trait
b) it is characterized by a decreased concentrration of electrolytes in the sweat
c) clinical manifestations are caused by obstruction resulting from increased viscosity of musous gland secretions
d) increased fat metabolism occurs
The answer in the manual is a.
The textbook and everywhere I've checked say that CF is recessive.
b is not correct because sodium and chloride are 2 to 5 times the normal range.
c sounds most correct
d is not correct because of the blocked pancreatic ducts, and without digestive enzymes fat, protein, and carbohydrates are poorly absorbed.
Which is the true statement?
And another question - this is True or False question:
Meconium ileus in the newborn is the earliest clinical manifestation of cystic fibrosis.
The manual answer is F.
But the textbook says "Meconium ileus in the neonate is the earliest clinical manifestation of CF."
