---

     B. Bulky greasy stools

     C. Moist, productive cough

     D. Meconium ileus

    

    

Correct Answer: C. Moist, productive cough

Noisy respirations and a dry non-productive cough are commonly the first of the respiratory signs to appear in a newly diagnosed client with cystic fibrosis (CF). The other options are the earliest findings. CF is an inherited (genetic) condition affecting the cells that produce mucus, sweat, saliva, and digestive juices. Normally, these secretions are thin and slippery, but in CF, a defective gene causes the secretions to become thick and sticky. Instead of acting as a lubricant, the secretions plug up tubes, ducts, and passageways, especially in the pancreas and lungs. Respiratory failure is the most dangerous consequence of CF.

Option A: A positive sweat test is one of the indications of cystic fibrosis.

Option B: A patient with CF experiences frequent greasy, bulky stools or difficulty with bowel movements as the thick mucus blocks the intestines.

Option D: Meconium ileus is one of the early signs of CF.
