If a nephrologist prescribes a 400 BFR for a patient, what else would you expect to find in the physician's order?

When a nephrologist prescribes a blood flow rate (BFR) of 400, it is important to ensure that the appropriate needle gauge is selected for the prescribed BFR. A blood flow rate of 400 ml/min is relatively high, and a 15 gauge needle is typically required to accommodate this flow effectively. This allows for sufficient blood volume to be extracted and returned to the patient without causing undue stress on the vascular access site.

The choice of needle gauge is critical in hemodialysis as it must be compatible with the flow rate to minimize risks such as hemolysis and to ensure that the treatment can be completed within the prescribed time. Using a needle that is too small in diameter may restrict blood flow, potentially leading to complications during the procedure.

While other options may mention aspects like detailed explanations or no additional information required, the most relevant factor when a specific BFR is prescribed is confirming that the appropriate equipment, such as the correct gauge of the needle, is used to achieve that flow rate safely and effectively. This practical application is essential for patient care and ensures that the treatment performed aligns with the physician's orders.
