Final answer:
Dialysis technicians may administer a certain amount of normal saline for severe hypotensive symptoms before alerting a nurse. The treatment for such symptoms often includes intravenous fluid replacement with saline solution to stabilize blood volume and blood pressure.
Step-by-step explanation:
For severe hypotensive symptoms, dialysis technicians may give up to a specified amount of normal saline and then inform the licensed nurse for further intervention. While the exact amount is not provided in the details given, it is important to note that treatment for hypovolemia often includes intravenous fluid replacement. In cases of significant blood loss or dehydration, initiating an IV with a saline solution can help restore blood volume and stabilize blood pressure. For example, under the assumption of a risk of blood loss of at least 500 ml, appropriate access and fluids would be available for treatment. Moreover, when dealing with hypovolemia, which can be caused by various factors including dehydration and bleeding, using an IV drip with the saline solution at a certain height can provide the necessary pressure for infusion.
