Correct Answer is D

Explanation

A) Incorrect. The sweat chloride test is used for CF diagnosis, but it does not analyze genetic mutations.

B) Incorrect. Chest X-rays are used to assess lung changes but do not directly confirm CF by analyzing genetic mutations.

C) Incorrect. Pulmonary function tests assess lung function but do not confirm CF by analyzing genetic mutations.

D) Correct. Genetic testing is a diagnostic procedure commonly used to confirm CF by analyzing the specific CF gene mutations present in an individual.

A. "CF is more common in females than males." B. "Being of African descent significantly increases the risk of developing CF." C. "A family history of CF is a risk factor, as it increases the likelihood of inheriting the mutated gene." D. "CF is unrelated to ethnicity, and anyone can be equally affected."

Correct Answer is C

Explanation

A) Incorrect. CF occurs at a similar frequency in both males and females.

B) Incorrect. CF is not significantly associated with any specific ethnicity, and the risk is not influenced by being of African descent.

C) Correct. A family history of CF increases the risk because CF is an autosomal recessive genetic disorder, and having affected family members increases the likelihood of carrying CF gene mutations.

D) Incorrect. While CF can affect individuals from any ethnicity, it is primarily a genetic disorder, and family history plays a crucial role in the risk of inheritance.
