Cholera patient is administrated by 'saline drip' because

Options

A. `Cl^(-)` ions are important component of blood plasma
B. `Na^(+)` ions help to retain water in the body
C. `Na^(+)` ions are important in transport of substances across membrane
D. `Cl^(+)` ions help in the formbrane of HCl in stomach for digestion

Explanation

**Step-by-Step Solution:**

1. **Understanding Cholera**: Cholera is an infectious disease caused by the bacterium Vibrio cholerae. It primarily leads to severe diarrhea, which results in significant fluid loss from the body.

2. **Symptoms of Cholera**: The main symptom of cholera is profuse diarrhea, which can lead to dehydration if not managed properly. This is a critical condition where the body loses a lot of water and electrolytes.

3. **Role of Saline Drip**: A saline drip is a medical treatment that involves administering a solution of sodium chloride (NaCl) in water directly into the bloodstream. This is crucial for patients suffering from cholera.

4. **Importance of Sodium (Na+) Ions**: Sodium ions (Na+) play a vital role in maintaining fluid balance in the body. They help retain water in the body, which is essential for preventing dehydration.

5. **Importance of Chloride (Cl-) Ions**: Chloride ions (Cl-) are also important as they are a component of blood plasma and contribute to various bodily functions, including the formation of hydrochloric acid (HCl) in the stomach for digestion.

6. **Mechanism of Action**: When saline (which contains Na+ and Cl-) is administered, it helps replenish the lost fluids and electrolytes. The presence of Na+ ions encourages the body to retain water, thus combating dehydration.

7. **Conclusion**: Therefore, administering a saline drip to a cholera patient is crucial to replace lost fluids and electrolytes, particularly to retain water in the body and prevent dehydration.
