B. Corticosteroids: Corticosteroids are used for inflammation and immune response modulation but are not effective in preventing motion sickness.

C. Phenothiazines: While phenothiazines (e.g., promethazine) are used to treat nausea and vomiting, they are less commonly used for motion sickness prevention compared to anticholinergics.

Correct Answer is B

Explanation

A. Fats: Restricting fats is not typically indicated in cirrhosis, unless the patient has specific issues like gallbladder disease or pancreatitis.

B. Protein: When ammonia levels rise in cirrhosis (leading to hepatic encephalopathy), restricting protein intake can help reduce the production of ammonia, as proteins are broken down into ammonia in the body.

C. Carbohydrates: Carbohydrates are generally not restricted in cirrhosis. They are important for energy, especially in patients with liver disease.

D. Water-soluble vitamins: There is no need to restrict water-soluble vitamins in cirrhosis unless there is a specific deficiency or malabsorption.
