A 15 gauge needle can accommodate which blood flow rate?

A 15 gauge needle is designed for hemodialysis and facilitates a blood flow rate (BFR) that is typically higher than that for smaller gauge needles. The range of 350 - 450 BFR is appropriate for a 15 gauge needle as it allows for efficient blood flow during dialysis, promoting optimal treatment outcomes.

This specific flow rate is crucial because higher flow rates enable the removal of more toxins and excess fluid from a patient's blood, significantly improving the efficacy of the dialysis process. Using a needle that can accommodate this flow rate ensures that the treatment is both effective and safe, minimizing the risk of complications associated with inadequate blood circulation during the procedure.

Other options fall outside the typical parameters established for a 15 gauge needle, making them less suitable for achieving efficient hemodialysis. Thus, focusing on the range of 350 - 450 BFR captures the essence of the functionality provided by this size of needle in a clinical setting.
