Which of the following is incorrect about re-infusing blood during treatment termination?

The statement regarding staff members leaving the patient's side if the patient is alert is incorrect because during critical procedures like blood re-infusion, maintaining constant supervision of the patient is essential to ensure their safety and respond quickly to any adverse reactions. Patient alertness does not eliminate the potential for complications, and the healthcare team must remain vigilant throughout the process.

In medical settings, particularly during blood re-infusion, patients can have unexpected reactions. For example, complications such as allergic responses, hemolysis, or changes in vital signs may occur. Therefore, even if the patient appears alert and stable, the presence of clinical staff is crucial to monitor the patient's condition closely.

The other statements provide accurate guidelines: arterial blood being returned before venous blood is a standard practice to ensure proper circulation; the blood pump being set at 150 to 200 is within the acceptable flow rate range to facilitate effective re-infusion; and the concern about an empty saline bag leading to an air embolism highlights the importance of proper fluid management during transfusions.
