Assertion : A cholera patient is given glucose, electrolytes, and water.
Reason: These plasmolyse the disease causing germs.

Answer

  1. Assertion is true, but reason is false.

Explanation:

Cholera is an acute infectious disease which is caused by Vibrio cholerae. The stools and the vomit of a cholera patient are full of cholera germs, and these may get into a healthy person when contaminated food or drink is taken by mouth. Since a large quantity of fluid and salts are rapidly lost through stools and vomit, therefore, the most important treatment is to replace the lost fluid and salts equally rapidly.
