Answer:
The statements that are not true regarding cystic fibrosis are:
Pancreatic enzyme deficiency causes increased mucus glands, increased viscosity of mucus, more secretions and infections, scarring of membranes (a).
Postural drainage is never used as part of the treatment (d).
Step-by-step explanation:
Cystic fibrosis (CF)is an inherited clinical condition, with an autosomal recessive inheritance pattern, characterized by the accumulation of very thick and viscous mucous secretion in organs such as the lungs, liver, intestines and pancreas.
When CF affects the pancreas it limits its exocrine and endocrine glandular function, affecting sugar metabolism and digestion, but it does not cause the mucous glands to produce the viscous secretion characteristic of the disease.
Pulmonary CF can lead to moderate to severe respiratory distress, with a high risk of lung infections. Postural drainage is one of the most widely used therapeutic alternatives to facilitate the expulsion of mucus from the airways.
The specific information above explains why the other options, b and c, are true.
