Question

multiple choice question
why are patients who have long - term urinary catheter use at greater risk for catheter - associated urinary tract infections?

patients are unable to urinate into the toilet

bacteria can enter the urinary tract by way of the catheter

the urine is more dilute

the urine is more concentrated

Explanation:

To determine the correct answer, we analyze each option:

• "Patients are unable to urinate into the toilet" is irrelevant to the risk of catheter - associated UTIs. The inability to urinate into a toilet does not directly cause infections.
• "Bacteria can enter the urinary tract by way of the catheter" is correct. A urinary catheter provides a direct pathway for bacteria from the external environment to enter the urinary tract. Over time, with long - term use, this increases the chance of infection.
• "The urine is more dilute" and "The urine is more concentrated" are incorrect. The concentration of urine is not the primary reason for the increased risk of catheter - associated UTIs. The main factor is the introduction of bacteria via the catheter.

Answer:

B. Bacteria can enter the urinary tract by way of the catheter
