The Organism That Most Often Causes Septicaemia Associated with an Intravenous

Question

The organism that most often causes septicaemia associated with an intravenous catheter is
A)Escherichia coli.
B)Staphylococcus epidermidis.
C)Pseudomonas aeruginosa.
D)hepatitis B virus.
E)none of the above because an intravenous catheter is sterile.

Accepted Answer

Staphylococcus epidermidis is a common skin bacteria that can grow on medical devices such as intravenous catheters, causing infections such as septicaemia. Escherichia coli and Pseudomonas aeruginosa can also cause septicaemia, but they are less commonly associated with intravenous catheters. The hepatitis B virus is a bloodborne virus, but it does not typically cause septicaemia. Intravenous catheters are not sterile, as they come into contact with the skin and the environment, so there is a risk of infection.
