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.

A. Coughing forcefully B. Controlled breathing exercises C. Huff coughing D. Exercising vigorously

Correct Answer is C

Explanation

A) Incorrect. While coughing is important, huff coughing is a more effective and less strenuous airway clearance technique for CF patients.

B) Incorrect. Controlled breathing exercises may help with relaxation but are not the primary airway clearance technique.

C) Correct. Huff coughing is a technique where the client takes a deep breath and forcefully exhales in short bursts, helping to move mucus from the airways.

D) Incorrect. Vigorous exercise is beneficial for CF patients but should not replace specific airway clearance techniques.
