A client with bacterial gastroenteritis asks the nurse about the mechanism of action of the causative bacteria. What response by the nurse is correct?
"The bacteria release toxins that directly damage the gastrointestinal lining."
"The bacteria invade and destroy the cells lining the small intestine."
"The bacteria induce an immune response leading to inflammation."
"The bacteria disrupt the balance of normal gut flora."
The Correct Answer is A
A) Correct. Many bacteria that cause gastroenteritis release toxins that directly damage the gastrointestinal lining.
B) Incorrect. While invasion of cells can occur with certain bacteria, it is not the primary mechanism of action for all bacterial gastroenteritis.
C) Incorrect. While inflammation is a common response to bacterial infection, it may not be the primary mechanism of all cases of bacterial gastroenteritis.
