Final answer:
Introducing antibiotics is not an indicator for a bladder washout; it is a treatment for the underlying infection, such as cystitis caused by bacteria like Escherichia coli. A bladder washout is used to remove physical obstructions like sediment or blood clots. The correct option is 1.
Step-by-step explanation:
The option that is not an indicator for a bladder wash out is to introduce antibiotics. A bladder washout, or bladder irrigation, is a procedure usually performed to remove or reduce the presence of sediment, such as blood clots after prostate surgery, or for symptomatic relief in cases of cystitis. However, introducing antibiotics is a treatment approach for dealing with the underlying infection rather than a mechanical cleaning method like bladder washouts.
Antibiotics are used to eradicate bacterial infections causing conditions like cystitis, which are diagnosed through symptoms and tests that may show the presence of white blood cells, red blood cells, or bacteria in the urine. Gram-negative bacteria, most commonly Escherichia coli, are frequent pathogens.
Introducing antibiotics would not be an indicator to perform a bladder washout but rather a concurrent treatment modality for the infection. Hence, 1 is the correct option.
