A family consumed some undercooked hamburger at a picnic and has since developed bloody diarrhea. The nurse knows which of the following statements listed below is correct regarding the infectious process?

Question

A)
Evasive factors that become more virulent by evading parts of the host's immune system
B)
Exotoxins that damage vascular endothelium causing bleeding and low platelet counts
C)
Adhesion factors that can anchor a pathogen firmly to the host tissue surfaces
D)
Invasive factors capable of destroying the cell membrane by utilization of enzymes

Answer 1

Ans:
B

Feedback:

Exotoxins can allow organisms to produce hemorrhagic colitis, which can be fatal. It is characterized by vascular endothelial damage, acute RF, and thrombocytopenia (low platelet counts). Toxic cell walls are classified as endotoxins. The ability to survive immune responses characterizes evasive factors. Adhesion factors and invasive factors are not involved in this situation.
