AIIMS 2019 Botany Bacterial Diseases MCQ Question

Type: MCQ-conceptual-Medium-Class 12

Assertion : Escherichia coli, Shigella sp. and Salmonella sp. are all responsible for diarrhoeal diseases.

Reason : Dehydration is common to all types of diarrhoeal diseases and adequate supply of fluids and electrolytes should be ensured.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If assertion is true but reason is false.

Correct Answer

Option B

Detailed Explanation

Option B is correct because it emphasizes the importance of rehydration in managing diarrhoeal diseases caused by pathogens like Shigella and Salmonella. These bacteria lead to fluid loss, primarily H₂O and electrolytes (e.g., Na⁺, K⁺), which can result in dehydration; thus, replenishing these fluids is crucial for recovery. Other options are not provided, but any alternative that neglects the significance of fluid and electrolyte replacement in diarrhoeal management would be incorrect, as it overlooks a fundamental aspect of treatment. Understanding the role of hydration in gastrointestinal infections is essential for effective patient care.
