Final answer:
Allowing urine to flow back into the bladder from the urinary drainage bag can lead to an increased infection risk, compromising the sterile environment of the bladder and potentially leading to urinary tract infections.
Step-by-step explanation:
If you allow urine to flow back into the bladder from the urinary drainage bag, it could lead to an increased infection risk. The bladder is meant to be a sterile environment, and the urine in the drainage bag may have been exposed to bacteria or other infectious agents. Preventing backflow is essential to maintain sterile conditions and reduce the risk of urinary tract infections (UTIs), which are more common in certain populations such as women, the elderly, and individuals with conditions like prostatitis or kidney stones. Furthermore, indwelling catheters, if not managed properly, can be a significant source of bladder infections. Proper care includes ensuring that urine does not flow back into the bladder to minimize infection risks.
