"CF results from a dominant genetic mutation inherited from one parent."

"CF occurs due to the presence of two dominant genetic mutations."

"CF is caused by a recessive genetic mutation inherited from both parents."

"CF is a non-genetic condition caused by environmental factors."

B) Incorrect. CF is not caused by dominant genetic mutations.

C) Correct. CF results from inheriting two recessive genetic mutations, one from each parent, leading to defective CFTR protein function.

D) Incorrect. CF is primarily a genetic disorder with well-established genetic mutations associated with its development.

Correct Answer is C

Explanation

A) Incorrect. Meconium ileus is a complication typically seen in newborns with CF, not in adults.

B) Incorrect. Failure to thrive is a concern in infants and young children with CF but not typically in adults.

C) Correct. Osteoporosis is a common complication in adults with CF due to malabsorption of calcium and vitamin D, chronic inflammation, and reduced physical activity.

D) Incorrect. Rapid growth and development are typically observed in adolescents, not as a complication but as a part of normal growth.

A. "Limit your protein intake to reduce mucus production." B. "Consume a high-fat diet to promote weight gain and calorie absorption." C. "Avoid all dairy products to prevent lung congestion." D. "Increase your intake of sugary snacks for quick energy."

Correct Answer is B

Explanation

A) Incorrect. Protein intake is important for growth and repair but should not be limited in CF. High-calorie intake is more critical.

B) Correct. CF can lead to malabsorption of fat-soluble vitamins and calories, so a high-fat diet is recommended to support weight gain and nutrient absorption.

C) Incorrect. Dairy products are a good source of calcium and calories, and they are generally well-tolerated by CF patients. Avoiding them is not necessary.

D) Incorrect. Increasing sugary snacks is not advisable for CF patients. They need a balanced diet to meet their nutritional needs.
