Question
Patients with indwelling catheters (long-term tubes inserted into body orifices for drainage, such as through the urethra and into the urinary bladder) are susceptible to infections becauseQuestion 12Answera.their immune systems are weakened.b.biofilms develop on catheters.c.infections can be transmitted from other people.d.injected solutions are contaminated.
Solution
Patients with indwelling catheters are susceptible to infections primarily because biofilms develop on catheters.
Here's a step-by-step explanation:
-
Indwelling catheters are tubes inserted into body orifices for drainage, such as through the urethra and into the urinary bladder.
-
Over time, these catheters can become a breeding ground for bacteria and other microorganisms.
-
These microorganisms can form a biofilm, which is a thin, slimy film of bacteria that adheres to a surface.
-
Biofilms provide a protective environment for bacteria, allowing them to multiply and become more resistant to antibiotics.
-
This can lead to a urinary tract infection, which can spread to other parts of the body if not treated promptly.
-
Therefore, the development of biofilms on catheters is a major reason why patients with indwelling catheters are susceptible to infections.
While it's also possible that their immune systems could be weakened, infections could be transmitted from other people, or injected solutions could be contaminated, the question specifically asks about the role of indwelling catheters, making biofilms the most relevant answer.
