Final answer:
The maximum acceptable level for water/dialysate culture results is less than 200 CFU/mL for water and less than 2,000 CFU/mL for dialysate in hemodialysis. An unacceptable level would thus be 1000 CFU/mL.
Therefore, option D is correct.
Step-by-step explanation:
The question addresses the topic of water and dialysate quality for medical procedures such as dialysis, where contamination levels must be strictly controlled. In medical environments, and specifically in dialysis, the acceptable level for water/dialysate culture results should not exceed a certain amount of colony-forming units (CFU) per mL to ensure the safety of the procedures.
According to standards set by organizations such as the AAMI (Association for the Advancement of Medical Instrumentation), the maximum acceptable level is less than 200 CFU/mL for water and less than 2,000 CFU/mL for dialysate in hemodialysis. Any dialysis water or dialysate with microbial counts higher than these limits is considered unacceptable, as it can pose risks of infection to patients undergoing treatment.
The answer to the student's question regarding the unacceptable level for water/dialysate culture results would be d) 1000 CFU/mL.
