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. Genetic testing is used to confirm CF but does not directly measure chloride ion concentration in sweat.

B) Incorrect. Chest X-rays may be used to assess lung changes in individuals with CF but are not used to measure chloride ion concentration in sweat.

C) Incorrect. Pulmonary function tests assess lung function but do not directly measure chloride ion concentration in sweat.

D) Correct. The sweat chloride test measures the concentration of chloride ions in sweat and is commonly used to confirm CF. Elevated sweat chloride levels are indicative of CF.

A. "CF primarily causes airway constriction due to inflammation." B. "In CF, the thickened mucus in the airways leads to chronic inflammation, infections, and lung damage." C. "CF results in the overproduction of surfactant, causing respiratory distress." D. "The CFTR protein in the lungs fails to produce enough oxygen for normal breathing."

Correct Answer is B

Explanation

A) Incorrect. While inflammation can be a consequence of CF, it is not the primary cause of airway constriction.

B) Correct. In CF, thickened mucus accumulates in the airways, leading to chronic inflammation, recurrent infections, and progressive lung damage.

C) Incorrect. CF does not result in the overproduction of surfactant, which is a substance that helps reduce surface tension in the lungs.

D) Incorrect. The CFTR protein does not produce oxygen but rather regulates chloride ion and water transport in the lungs
