A nurse is providing education to a client with cystic fibrosis (CF). Which dietary recommendation is most appropriate for the client?

"Limit your protein intake to reduce mucus production."

"Consume a high-fat diet to promote weight gain and calorie absorption."

"Avoid all dairy products to prevent lung congestion."

"Increase your intake of sugary snacks for quick energy."

Answer and Explanation

The Correct Answer is B

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.

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. "You both have a family history of CF, so it is impossible for your child to inherit the condition." B. "Since you both carry a single CF gene mutation, your child has a 100% chance of developing CF." C. "Your child will inherit CF only if both of you pass on a copy of the CF gene mutation." D. "The risk of your child having CF is solely determined by the mother's genetic history."

Correct Answer is C

Explanation

A) Incorrect. Both partners having a family history of CF increases the likelihood of carrying CF gene mutations, making it possible for their child to inherit the condition.

B) Incorrect. Having a single CF gene mutation (carrier status) does not guarantee that a child will develop CF; it requires inheriting two CF gene mutations, one from each parent.

C) Correct. CF is an autosomal recessive genetic disorder, which means that a child will have CF only if they inherit two copies of the CF gene mutation, one from each parent.

D) Incorrect. The risk of a child having CF is determined by both parents' genetic history, not solely the mother's.
