Rationale:
A. Limiting fats is inappropriate for children with cystic fibrosis (CF) because they require a high-calorie, high-fat diet to maintain growth due to malabsorption.
B. Increasing calories by 50% is appropriate, but limiting salt is not recommended; children with CF often require extra salt due to excessive losses in sweat.
C. While vitamins are important, CF patients require fat-soluble vitamins (A, D, E, K) rather than B complex and C specifically.
D. Adding pancreatic enzymes four to five times a day is essential for children with CF who have pancreatic insufficiency. These enzymes aid in digestion and absorption of nutrients, improving growth and nutritional status.

Rationale:
A. Inhaled bronchodilators have limited efficacy in mild bronchiolitis and are not routinely recommended for initial treatment.
B. Over-the-counter antihistamines are not effective for bronchiolitis in infants.
C. Cough suppressants are not recommended in infants due to potential side effects and lack of proven benefit.
D. Supportive care is the mainstay of treatment for mild bronchiolitis, including ensuring adequate hydration, monitoring oxygenation, and providing comfort measures. Most cases are self-limited and resolve without pharmacologic intervention.
