Answer and Explanation

The Correct Answer is D

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 C

Explanation

A. Mucositis: This refers to painful inflammation and ulceration of the mucous membranes, often without plaques.

B. Canker sores: These are small, shallow ulcers with a yellowish center and red border, not white plaques.

C. Thrush: Thrush is an oral fungal infection (caused by Candida albicans) characterized by white, milk-curd-like plaques on the mucosa.

D. Cold sores: Cold sores are caused by herpes simplex virus and appear as blisters, not white plaques.

A. Lie on the right side after meals. B. Eat only small meals. C. Keep the bed flat. D. Drink three glasses of fluid with each meal.

Correct Answer is B

Explanation

A. Lie on the right side after meals: This position is not effective in reducing regurgitation. Lying on the left side or maintaining an upright position after eating is generally better for avoiding reflux.

B. Eat only small meals: Smaller meals reduce the risk of overfilling the stomach, which helps minimize regurgitation and pressure on the esophageal stent.

C. Keep the bed flat: Keeping the bed flat increases the risk of regurgitation by allowing stomach contents to flow backward into the esophagus.

D. Drink three glasses of fluid with each meal: Excessive fluid during meals may increase stomach volume and the risk of regurgitation.
