Answer:
Answer is A. Fatty stools.
Explanation:
Cystic fibrosis is a disorder which is caused by a defect in CFTR gene. When this gene is not working as expected, it will cause the formation of thick sticky mucus. this disorder is hereditary.
It should be noted that, the effect of this disorder may cause the thick sticky mucus to block the pancreas, and this will prevent the enzyme produced by the pancreas, which is needed in the digestion of protein , from reaching the intestine where the digestion will takes place. This will automatically prevent the body from accessing or absorbing the required nutrients.
In this case, the administration of a pancreatic enzyme, pancrelipase, will digest the protein and allow the body to absorb the necessary nutrient. This will increase the nutritional status of the infant.
